It can be included. Meanwhile, the second content may be a video type content, but is not limited thereto. The processor 130 may receive second metadata and image data corresponding to each of the plurality of second contents through the communication interface 110. According to one example, the first metadata and the second metadata may be text information, but are not limited thereto.

According to one example, the processor 130 may compare the first metadata stored in the memory 120 and the second metadata received through the communication interface 110 for each corresponding type.

For example, the processor 130 identifies at least one second metadata that matches broadcaster information and broadcast channel information included in the first metadata among the second metadata corresponding to each of the plurality of second contents, and , the program information included in the identified second metadata may be compared with the program information included in the first metadata. A specific method of comparing the first metadata and the second metadata will be described in detail with reference to FIG. 4.

According to one embodiment, the processor 130 may identify content that is the same as at least one of the plurality of first contents among the plurality of second contents.

According to one example, the processor 130 may identify content that is the same as at least one of the plurality of first contents among the plurality of second contents based on the similarity between the first metadata and the second metadata. For example, when any one of the second metadata is identified as having a similarity of more than a preset value to one of the first metadata, the processor 130 generates a first metadata corresponding to one of the first metadata. The content and the second content corresponding to one of the second metadata can be identified as the same content.

However, it is not limited to this, and of course, any one of the second metadata may have a similarity greater than a preset value with at least one of the first metadata.

Meanwhile, according to one embodiment, the processor 130 may manage a plurality of first contents and a plurality of second contents based on the identification result. According to one example, if content that is the same as at least one of the plurality of first contents is identified among the plurality of second contents based on the similarity of the first metadata and the second metadata, the processor 130 stores the identified content in at least one of the plurality of second contents. The second metadata corresponding to the identified second content can be updated based on common key information included in the corresponding first metadata.

Here, the common key information refers to identification information for identifying each of a plurality of contents, and has different common key information depending on each of the plurality of contents. For example, when common key information corresponding to specific content exists, at least one metadata corresponding to the specific content may include the same common key information.

According to one example, when any one of the second content is identified as the same content as any one of the plurality of first contents, the processor 130 determines the common content included in the first metadata corresponding to one of the first contents. Key information may be identified, and the second metadata may be updated so that the identified common key information is included in the second metadata corresponding to any one of the second content. This will be explained in detail through FIGS. 5A to 5C.

Figure 3 is a flowchart explaining a control method of an electronic device according to an embodiment.

According to FIG. 3, according to one embodiment, the control method stores second metadata corresponding to each of a plurality of second contents included in a real-time broadcast signal to each of a plurality of first contents provided by at least one content provider. It can be compared with the first metadata (S310).

According to one example, the processor 130 first generates at least one second metadata that matches broadcaster information and broadcast channel information included in the first metadata among the second metadata corresponding to each of the plurality of second contents. can be identified.

For example, assume that the broadcaster information and broadcast channel information included in the first metadata corresponding to one of the plurality of first contents are “Broadcaster 1” and “Channel 1”, respectively. The processor 130 compares the second metadata corresponding to the received plurality of second contents, and selects “Broadcaster 1” and “Broadcaster 1” and broadcast channel information among the second metadata corresponding to the plurality of second contents, respectively. The second metadata, which is “Channel 1”, can be identified.

Subsequently, according to one example, the processor 130 may compare program information included in the identified second metadata with program information included in the first metadata. For example, the processor 130 may obtain similarity between the first metadata and the second metadata by comparing program information included in the identified second metadata and program information included in the first metadata. The specific method for obtaining similarity will be described in detail with reference to FIGS. 5A to 5C.

Meanwhile, according to one example, the processor 130 may preferentially compare each of the broadcast operator information and broadcast channel information included in the first metadata and the second metadata and then compare each program information, but is not limited to this. Of course, any one of broadcasting operator information, broadcasting channel information, and program information may be compared with priority, or broadcasting operator information, broadcasting channel information, and program information may be compared without priority.

Next, according to one embodiment, the control method may identify content that is the same as at least one of the plurality of first contents among the plurality of second contents based on the similarity between the first metadata and the second metadata (S320).

According to one example, the processor 130 selects any one of the second metadata corresponding to a plurality of second contents and has a similarity of more than a preset value to the first metadata corresponding to one of the first contents. When data is identified, either the second content corresponding to any identified second metadata and the first content corresponding to the first metadata can be identified as the same content.

Next, according to one embodiment, the control method may manage a plurality of first contents and a plurality of second contents based on the identification result (S330).

According to one example, if any one of the second content corresponding to any identified second metadata and the first content corresponding to the first metadata is identified as the same content, the processor 130 selects the first content Identify common key information included in the first metadata corresponding to any one of the content, and update the second metadata so that the identified common key information is included in the second metadata corresponding to any one of the second content. there is. Subsequently, the processor 130 may store the updated second metadata in the memory 120 .

According to the above-described embodiment, the processor 130 can identify whether the same content as the content stored in the memory 120 exists among a plurality of content received from a real-time broadcast signal, and based on this, select the same content among the received content. Metadata corresponding to the identified content can be stored in the memory 120. Accordingly, different types of metadata corresponding to the same content can be stored, and the probability that the electronic device 100 can identify duplicate content among received content increases.

FIG. 4 is a diagram illustrating a method of comparing first metadata and second metadata according to an embodiment.

According to FIG. 4, according to one embodiment, the memory 120 includes program information, broadcaster information, and broadcast information corresponding to each of a plurality of first contents provided by at least one content provider received from an external server (not shown). First metadata 400 including channel information may be stored.

According to one example, the first metadata 400 may include a plurality of metadata 401 to 403 corresponding to each of a plurality of first contents received from an external server, and a plurality of metadata included in the first metadata. The metadata may include program information, broadcaster information, common key information, and broadcast channel information, respectively.

According to one example, the program information is at least one of title information (“Title”), description information (“Description”), running time information (“Time”), and information about whether the content is paid (“Free?”) may include. For example, title information included in the first metadata 401 corresponding to content A may be “Title 1”, description information may be “A”, and running time information may be “C”.

Meanwhile, according to one example, the first metadata corresponding to each of the plurality of first contents may include broadcasting operator information and broadcasting channel information. For example, broadcaster information included in the first metadata 401 corresponding to content A may be “Broadcaster 1” and broadcast channel information may be “Channel 1”.

That is, the memory 120 may store first metadata including program information, broadcasting operator information, and broadcasting channel information corresponding to each of a plurality of first contents (e.g., content A to content N). , the first metadata may include a plurality of metadata. Each of the plurality of metadata may include at least one of program information, broadcasting operator information, and broadcasting channel information.

Meanwhile, according to one embodiment, the processor 130 generates a second meta message including program information, broadcaster information, and broadcast channel information corresponding to each of the plurality of second contents included in the real-time broadcast signal through the communication interface 110. Data 410 may be received.

According to one example, the second metadata 410 may include a plurality of metadata 411 to 413 corresponding to each of a plurality of second contents received from an external server (not shown), and the second metadata The plurality of metadata 411 to 413 included may include program information, broadcasting operator information, and broadcasting channel information, respectively. Meanwhile, according to one example, there may be a plurality of metadata corresponding to one piece of content. For example, unlike what is shown in FIG. 4, it goes without saying that a plurality of metadata corresponding to any one content may exist in the memory 120.

According to one embodiment, the processor 130 compares the first metadata and the second metadata to identify content that is the same as the first content corresponding to the first metadata among the second content corresponding to the second metadata. You can.

According to one example, the processor 130 may include at least one piece of second metadata 410 that matches the broadcast operator information and broadcast channel information included in the first metadata 400, respectively, corresponding to each of the plurality of second contents. Second metadata can be identified. For example, the processor 130 compares each of the plurality of metadata included in the received second metadata 410 with each of the plurality of metadata included in the first metadata 400, At least one second metadata matching the broadcast operator information and broadcast channel information included in 400 may be identified.

As shown in FIG. 4, for example, the processor 130 determines whether the broadcaster information (Broadcaster 1) and the broadcast channel information (Channel 1) of any one of the second metadata 411 are any of the first metadata. By comparing one (401) broadcast operator information (Broadcaster 1) and broadcast channel information (Channel 1), the broadcast operator information and broadcast channel information included in one of the second metadata (411) are among the first metadata. It can be identified as matching the broadcasting operator information and broadcasting channel information included in any one (401).

However, it is not limited to this, and according to one example, the processor 130 divides at least one of broadcast channel identifier information, channel name information, channel number information, channel frequency information, and channel picture quality information included in broadcast channel information into corresponding types. Of course, comparisons are possible.

For example, the processor 130 may identify whether the channel name information of one of the second metadata 411 matches the channel name information of one of the first metadata 401. Or, for example, the processor 130 may send broadcast channel identifier information, channel name information, channel number information, channel frequency information, and channel picture quality information included in the broadcast channel information of any one of the second metadata 411 to the first metadata. It is also possible to identify whether it matches each of the broadcast channel identifier information, channel name information, channel number information, channel frequency information, and channel picture quality information included in the broadcast channel information of any one of the metadata 401. In this case, according to one example, the processor 130 selects the broadcast channel of any one of the second metadata 411 when each of the broadcast channel identifier information, channel name information, channel number information, channel frequency information, and channel picture quality information matches. The information may be identified as matching broadcast channel information of any one of the first metadata (401).

Meanwhile, according to one embodiment, the processor 130 compares the program information included in the identified second metadata with the program information included in the first metadata, and corresponds to the second metadata having a similarity of more than a preset value. The second content may be identified as the same content as the first content corresponding to the first metadata.

According to an example, among the second metadata 410 corresponding to each of the plurality of second contents, at least one second metadata that matches the broadcast operator information and broadcast channel information included in the first metadata 400 Assume the identified case. The processor 130 may compare program information included in the identified at least one second metadata and program information included in the first metadata matched with the identified at least one second metadata for each corresponding type. . Subsequently, the processor 130 may identify the second content corresponding to the second metadata having a similarity greater than a preset value as the same content as the first content corresponding to the first metadata.

For example, the broadcast operator information and broadcast channel information included in any one of the second metadata 411 are identified as matching the broadcast operator information and broadcast channel information included in any one of the first metadata 401. Suppose a case has been made. The processor 130 compares the program information included in one of the second metadata 411 with the program information included in one of the first metadata 401 for each corresponding type, and selects one of the second metadata. The title information (“Title 1”) included in one 411 and the title information (“Title 1”) included in one of the first metadata 401 may be identified as matching. Subsequently, the processor 130 may identify the second content (content A) corresponding to the second metadata as the same content as the first content (content A) corresponding to the first metadata.

Alternatively, according to one embodiment, the processor 130 may identify the first metadata and the second metadata that is greater than or equal to a preset similarity value based on information about whether the content included in the program information is paid. .

According to the above-described example, the electronic device 100 may identify metadata that matches the first metadata stored in the memory 120 among the second metadata corresponding to each of the plurality of received second contents, and Based on this, it is possible to identify content that is the same as the first content among a plurality of second content.

5A to 5C are diagrams for explaining a method of managing first content and second content according to an embodiment.

According to one embodiment, the processor 130 compares the program information included in the first metadata and the program information included in the second metadata to generate second content corresponding to the second metadata having a similarity of more than a preset value. can be identified as the same content as the first content corresponding to the first metadata.

According to one example, the processor 130 may identify the number of matching types by comparing the program information included in the identified second metadata and the program information included in the first metadata for each corresponding type. According to one example, program information may include at least one of title information, description information, and running time information. Here, the title information is title information corresponding to the content, and the description information is text information containing a description of the content. Running time information is information about the playback time of content.

According to one example, if the number of matched types is identified as being greater than or equal to a preset number, the processor 130 may identify the identified second metadata as having a similarity greater than or equal to a preset value with the first metadata. The preset number may be, for example, 1, but it is not limited to this and, of course, may be changed based on user input.

Subsequently, according to one example, the processor 130 may identify the second content corresponding to the second metadata having a similarity of more than a preset value as the same content as the first content corresponding to the matched first metadata. .

According to FIG. 5A, according to an embodiment, the processor 130 combines each of the plurality of metadata 511 and 512 included in the received second metadata 510 into a plurality of metadata included in the first metadata 500. By comparing each of the metadata 501 to 503, identify any second metadata 512 that matches the broadcasting operator information and broadcast channel information included in any one of the first metadata 500 (501). can do. Additionally, the processor 130 may identify another second metadata 511 that matches the broadcaster information and broadcast channel information included in the other 502 of the first metadata 500.

Subsequently, according to one embodiment, the processor 130 may use title information, description information, and running time information included in any one of the identified second metadata 512 and any one of the first metadata 501. By comparing title information, description information, and running time information for each corresponding type, two types (description information and running time information) can be identified as matching. In addition, the processor 130 may use title information, description information, and running time information included in another identified second metadata 511 and title information and description information included in one first metadata 502. And by comparing the running time information for each corresponding type, it can be identified that one type (title information) matches.

Subsequently, according to one embodiment, the processor 130 selects one second metadata 512 and the other second metadata 511 where the number of matched types is a preset number of one or more. It can be identified as having a similarity greater than a preset value with the first metadata 501 and the other metadata 502.

Subsequently, according to one embodiment, the processor 130 combines the second content (content A) corresponding to any second metadata 512 with a similarity of more than a preset value to any one of the first metadata 501. It can be identified as the same content as the first content (content A) corresponding to . In addition, the processor 130 divides the second content (content A) corresponding to any second metadata 511 having a similarity of more than a preset value into the first content corresponding to any one of the first metadata 502. It can be identified as the same content as the content (Content A).

Meanwhile, according to one embodiment, the processor 130 may update the second metadata corresponding to the second content identified as the same content and store it in the memory 120.

First, according to one example, when the second content that is the same as any one of the plurality of first contents among the plurality of second contents is identified, the processor 130 operates the common key (Common key) included in the first metadata corresponding to any one of the plurality of second contents. The second metadata corresponding to the identified second content may be updated based on the Key) information.

According to FIG. 5B, for example, when the second content corresponding to any one second metadata 512 is identified as the same content as the first content corresponding to any one first metadata 501, the processor (130) sets the second metadata 512 so that the common key information (Key A) included in any identified first metadata 501 is included in the second metadata 512 corresponding to the second content identified as the same content. By updating the metadata, updated second metadata 512-1 can be obtained. In addition, when the second content corresponding to another second metadata 511 is identified as the same content as the first content corresponding to another first metadata 502, the processor 130 By updating the second metadata so that the common key information (Key A) included in another first metadata 502 is included in the second metadata 511 corresponding to the second content identified as the same content, Another updated second metadata 511-1 can be obtained.

Subsequently, according to one example, the processor 130 may store the updated second metadata in the memory 120 . For example, the processor 130 may store one of the updated second metadata 512-1 and the other updated second metadata 511-1 in the memory 120.

Accordingly, the processor 130 can obtain updated first metadata 500-1 including a plurality of updated second metadata.

According to FIG. 5C, according to one embodiment, the processor 130 provides updated first metadata and first metadata corresponding to each of a plurality of third contents provided by at least one content provider received from an external server (not shown). 3 By comparing metadata, content that is the same as at least one of the plurality of first contents among the plurality of third contents can be identified. According to one example, the third content may be a video type content, but is not limited thereto. Meanwhile, according to one example, the third metadata may include a plurality of metadata corresponding to each of a plurality of third contents received from an external server, and the plurality of metadata may include program information, broadcaster information, and broadcast channel information. may include each.

According to one example, the memory 120 may store updated first metadata 500-1 including a plurality of updated second metadata 511-1 and 512-1. The processor 130 may receive third metadata 520 corresponding to each of a plurality of third contents provided by at least one content provider through the communication interface 110.

According to one example, the processor 130 combines each of the plurality of metadata 521 and 522 included in the received third metadata 520 with the plurality of metadata included in the updated first metadata 500-1. In comparison with each of (501 to 503, 511-1, and 512-1), broadcaster information and broadcast channel information included in at least some (501 and 512-1) of the updated first metadata (500-1); Any matching third metadata 522 can be identified. In addition, the processor 130 generates another third metadata 521 that matches the broadcaster information and broadcast channel information included in at least some of the updated first metadata 500-1 (502 and 511-1). ) can be identified.

First, according to an example, the processor 130 stores title information, description information, and running time information included in any identified third metadata 522 to the matched first metadata 501 and 512-1. The included title information, description information, and running time information are compared for each corresponding type, so that one type (running time information) is matched with any one matched first metadata 501, and the other matched first metadata 501 is matched. It can be identified that two types (title information and running type information) match the first metadata 512-1.

Accordingly, the processor 130 determines that any one of the identified third metadata 522 and the matched first metadata 501 and 512-1 has a similarity value greater than or equal to a preset value. The third content corresponding to one third metadata 522 can be identified as the same content (content A) as the second content corresponding to the matched first metadata 501 and 512-1. Here, the content corresponding to each of the matched first metadata 501 and 512-1 is the same content (content A).

In addition, according to one example, the processor 130 stores title information, description information, and running time information included in another identified third metadata 521 to the matched first metadata 502 and 511-1. By comparing each type corresponding to the included title information, description information, and running time information, two types (title information and running time information) are matched with one matched first metadata 502, and the other type is matched with the first metadata 502. It can be identified that three types (title information, description information, and running type information) are matched with the matched first metadata 511-1.

Accordingly, the processor 130 determines that the third content corresponding to any one of the identified third metadata 521 is the same as the first content corresponding to the matched first metadata 502 and 511-1 ( It can be identified as content A). Here, the content corresponding to each of the matched first metadata 502 and 511-1 is the same content (content A).

Meanwhile, according to one embodiment, the processor 130 updates the updated first metadata and third metadata corresponding to each of a plurality of third contents provided by at least one content provider received from an external server (not shown). When comparing, the comparison can be made excluding the broadcast channel information included in each.

According to one example, when the third metadata corresponding to each of the plurality of third contents provided by the content provider does not include broadcast channel information, the processor 130 selects the program included in the updated first metadata. The program information and broadcaster information included in the information and broadcaster information and the third metadata corresponding to each of the plurality of third contents provided by at least one content provider received from an external server (not shown) are typed correspondingly. By comparing each, any third metadata that matches the broadcaster information and program information included in the updated first metadata may be identified.

Accordingly, even when the third content does not include broadcast channel information, the electronic device 100 can identify content that is the same as at least one of the plurality of first contents among the plurality of third contents.

Returning to FIG. 2, according to one embodiment, the processor 130 compares the program information included in the second metadata and the program information included in the first metadata by corresponding type using text information included in the program information. You can. According to one example, the processor 130 may compare program information included in the second metadata and program information included in the first metadata for each corresponding type through a learned neural network model.

According to one example, the processor 130 identifies the similarity between title information, which is text information included in program information corresponding to first metadata, and title information, which is text information included in program information corresponding to second metadata. , If the similarity is identified as being greater than or equal to a preset value, it can be identified that the title information corresponding to the first metadata and the title information corresponding to the second metadata are matched.

Or, according to one example, the processor 130 identifies the similarity between the text corresponding to the description information included in the first metadata and the text corresponding to the description information included in the second metadata, and sets the similarity to a preset value. If it is identified as being abnormal, it may be identified that the description information corresponding to the first metadata and the description information corresponding to the second metadata match.

Alternatively, according to one example, the processor 130 identifies the similarity between the text corresponding to the running time information included in the first metadata and the text corresponding to the running time information included in the second metadata, and determines the similarity. If it is identified as being more than the set value, it may be identified that the running time information corresponding to the first metadata and the running time information corresponding to the second metadata match.

Meanwhile, according to one embodiment, the processor 130 obtains a similarity value through a learned neural network model and compares the program information included in the identified second metadata with the program information included in the first metadata to obtain a similarity value. The second content corresponding to the second metadata having a similarity value greater than or equal to the similarity value may be identified as the same content as at least one of the plurality of first contents.

Artificial neural networks may include deep neural networks (DNN), such as Convolutional Neural Network (CNN), Recurrent Neural Network (RNN), Restricted Boltzmann Machine (RBM), Deep Belief Network (DBN), Bidirectional Recurrent Deep Neural Network (BRDNN) or Deep Q-Networks, etc., but are not limited to the above examples.

According to one example, the memory 120 may store a neural network model learned using first metadata for learning and second metadata for learning that matches the first metadata for learning as learning data. According to one example, the processor 130 receives first metadata corresponding to each of a plurality of first contents provided by at least one content provider received from an external server (not shown) and the communication interface 110. When the second metadata corresponding to each of the plurality of second contents included in the real-time broadcast signal is received, the learned neural network model can be obtained by inputting it into the neural network model.

According to one example, the processor 130 receives first metadata corresponding to each of a plurality of first contents provided by at least one content provider received from an external server (not shown) and the communication interface 110. A reference similarity value may be obtained by inputting a plurality of metadata including second metadata corresponding to each of a plurality of second contents included in the real-time broadcast signal into the learned neural network model.

According to one example, the processor 130 identifies the similarity between the title information corresponding to the first metadata and the title information corresponding to the second metadata, and when the identified similarity is identified as being equal to or greater than the obtained reference similarity value, the processor 130 It can be identified that the title information corresponding to the first metadata and the title information corresponding to the second metadata match.

Alternatively, according to one example, the processor 130 identifies the similarity between the description information corresponding to the first metadata and the description information corresponding to the second metadata, and when the identified similarity is identified as being equal to or greater than the obtained reference similarity value, It can be identified that the description information corresponding to the first metadata and the description information corresponding to the second metadata match.

Accordingly, the electronic device 100 can identify whether program information including title information, description information, and running time information included in metadata matches through the obtained standard similarity value.

Figures 6A to 6C are diagrams to explain a control method when broadcast channel information does not match, according to an embodiment.

According to FIG. 6A, according to one embodiment, the processor 130 identifies that the broadcast channel information included in the received second metadata 610 and the broadcast channel information included in the first metadata 600 do not match. If so, broadcasting channel information corresponding to the second metadata 610 can be obtained from video data included in the real-time broadcasting signal using a preset algorithm.

According to one example, the processor 130 stores broadcast channel information (“Channel 3”) included in the received second metadata 610 and broadcast channel information (“Channel 1”) included in the first metadata 600. and “Channel 2”) are identified as not matching, broadcast channel information of content corresponding to the video data can be obtained from the video data through an optical character recognition (OCR) algorithm. The Optical Character Recognition (OCR) algorithm is an algorithm that extracts text information by analyzing image-type data.

According to FIG. 6C, according to an example, the processor 130 may receive image data corresponding to each of a plurality of second contents included in the real-time broadcast signal received through the communication interface 110. If the processor 130 identifies that the broadcast channel information included in the received second metadata 610 and the broadcast channel information included in the first metadata 600 do not match, the processor 130 uses an OCR algorithm to retrieve the image data. Broadcast channel information 60 corresponding to the second content can be obtained.

For example, the processor 130 may obtain “Channel 1”, which is text information corresponding to the broadcast channel information 60 of the second content, using an OCR algorithm, and the acquired broadcast channel information 60 is included. If possible, the second metadata 610 can be updated. However, the present invention is not limited to this, and according to one example, the processor 130 may obtain title information corresponding to the second content from image data using an OCR algorithm.

In this case, according to one example, the processor 130 uses an OCR algorithm that allows image data corresponding to the relatively upper side of the received image to have a greater weight, and selects broadcast channel information 60 corresponding to the second content from the image data. ) can be obtained. As shown in FIG. 6C, broadcast channel information or title information often exists relatively on the upper side of the video, and the processor 130 uses an OCR algorithm to give video data corresponding to the relatively upper side a greater weight. Broadcast channel information 60 corresponding to the second content can be obtained from.

Meanwhile, according to FIG. 6B, according to one embodiment, the processor 130 compares the acquired broadcast channel information (“Channel 1”) with the broadcast channel information included in the first metadata 600, and determines the obtained broadcast channel information. The second metadata 610-1 including (“Channel 1”) can be identified as matching the broadcast operator information and broadcast channel information included in any one of the first metadata 600 (601). .

Subsequently, according to one embodiment, the processor 130 selects a plurality of first contents from among the plurality of second contents based on the similarity between one of the first metadata 601 and the updated second metadata 610-1. It is possible to identify content that is identical to at least one of the content, and manage a plurality of first content and a plurality of second content based on the identification result.

Accordingly, even when the first metadata among the second metadata and the broadcast channel information do not match, the processor 130 uses the video data to identify content that is the same as at least one of the plurality of first contents among the second content. You can do it.

7A to 7C are diagrams to explain a control method when the similarity is less than a preset value, according to an embodiment.

According to one embodiment, the processor 130 compares the program information included in the identified second metadata with the program information included in the first metadata, and if it is identified as having a similarity less than a preset value, performs a preset algorithm. Using this method, title information and description information corresponding to the second metadata identified from the video data included in the real-time broadcast signal can be obtained. According to one example, the processor 130 compares the program information included in the identified second metadata with the program information included in the first metadata, and if the number of matching types is less than one, uses a preset algorithm. Thus, title information and description information corresponding to the second metadata identified from the video data included in the real-time broadcast signal can be obtained. However, it is not limited to this, and of course, the similarity may change depending on user input.

According to FIG. 7A, according to one example, the processor 130 first identifies any one first metadata 701 that matches the broadcast channel information and broadcast operator information included in the received second metadata 710. You can. Subsequently, according to one example, the processor 130 may compare program information included in the identified second metadata 710 with program information included in any one of the first metadata 701.

Subsequently, according to an example, the processor 130 includes program information including title information, description information, and running time information corresponding to the identified second metadata 710 in any one of the first metadata 701. By comparing the program information and the corresponding type, it is identified that the number of matching types is 0, and the program information included in the identified second metadata 710 is not included in any one of the first metadata 701. It can be identified as having a similarity lower than a preset value with the included program information.

Subsequently, according to one example, the processor 130 may obtain program information of content corresponding to the image data from the image data through an optical character recognition (OCR) algorithm.

According to FIG. 7C , according to an example, the processor 130 may receive image data corresponding to each of a plurality of second contents included in a real-time broadcast signal received through the communication interface 110. If the program information included in the received second metadata 710 and the program information included in any one of the first metadata 701 are identified as having a similarity less than a preset value, the processor 130 performs an OCR algorithm. Title information 70 corresponding to the second content can be obtained from video data using . Alternatively, although not shown in FIG. 7C, the processor 130 may obtain description information corresponding to the second content from image data using an OCR algorithm.

For example, the processor 130 may acquire “Title 1”, which is text information corresponding to the title information 70 of the second content, using an OCR algorithm, and create a second content to include the obtained program information 70. 2 Metadata 710 can be updated. However, it is not limited to this, and according to one example, the processor 130 obtains description information corresponding to the second content from the image data using an OCR algorithm, and creates the second metadata 710 to include the obtained information. You can also update it.

In this case, according to one example, the processor 130 extracts program information 70 corresponding to the second content from the image data using an OCR algorithm that allows image data corresponding to the relatively upper side of the received image to have a greater weight. can be obtained.

Meanwhile, according to FIG. 7B, according to one embodiment, the processor 130 compares program information including at least one of the obtained title information or description information with program information included in the first metadata, The second content corresponding to the second metadata having similarity may be identified as the same content as the first content corresponding to the first metadata.

According to one example, when the second metadata 710-1 is updated so that at least one of the obtained title information or description information includes updated program information, the processor 130 operates the updated second metadata 710-1. By comparing the program information in 1) by type corresponding to any one of the first metadata 701, it can be identified that the number of matching types is 1 (title information). Accordingly, the processor 130 may identify the updated second metadata 710-1 as having a similarity greater than or equal to a preset value with any one of the first metadata 701.

Subsequently, according to one example, the processor 130 may determine the similarity between any one of the first metadata 701 and the updated second metadata 710-1 to be greater than or equal to a preset value. It is possible to identify the corresponding second content as being the same as the first content corresponding to any one first metadata, and to manage a plurality of first contents and a plurality of second contents based on the identification result.

Accordingly, the processor 130 may identify content that is the same as at least one of the plurality of first contents among the second content using the image data even when the first metadata and the program information among the second metadata do not match. It becomes possible.

Meanwhile, according to one embodiment, the processor 130 may identify the same content using image address information corresponding to the content. According to one example, the memory 120 may further include image address information corresponding to each of the plurality of first contents. Here, the video address information refers to address information through which video data corresponding to the first content can be obtained, including URL (Uniform Resource Locator) information where the video data of the content is stored. However, the present invention is not limited to this, and trailer image data corresponding to each of a plurality of first contents may be stored in the memory 120 . Here, according to one example, the trailer video data may be video data (or teaser video) with a running time less than a preset size corresponding to the content.

According to one example, the second metadata 710-1 containing at least one of title information or description information obtained using a preset algorithm is less than the preset value of any one of the first metadata 701. We assume a case identified as having a degree of similarity. If the second metadata 710-1 is identified as having a similarity less than a preset value, the processor 130 compares the video data included in the real-time broadcast signal and the video data obtained based on the video address information to identify the second metadata 710-1. It is possible to identify whether the second content corresponding to the second metadata is the same content as the first content corresponding to the first metadata.

For example, the processor 130 obtains image data of the first content corresponding to one piece of first metadata 701 based on the image address information stored in the memory 120, and converts it into second metadata ( Is the second content corresponding to the second metadata 710-1_ identified by comparing with the image data corresponding to 710-1 the same content as the first content corresponding to any one of the first metadata 701? According to one example, the processor 130 extracts an image frame from each image data, compares them, and determines that the second content corresponding to the identified second metadata is the first metadata. 1 It is possible to identify whether the content is the same as the content.

Figure 8 is a diagram for explaining a method of providing UI according to an embodiment.

According to FIG. 8 , according to one embodiment, the processor 130 may provide a UI in which information about content identified as the same content is not repeatedly provided based on the identification result.

According to one example, the processor 130 determines that the second content corresponding to the second metadata is converted into the first content corresponding to the first metadata based on the program information, broadcasting operator information, and broadcasting channel information included in the second metadata. If the content is identified as the same content, a UI that does not overlap the second content and the first content can be provided.

As shown in the upper diagram of FIG. 8, the second content 80-1 corresponding to the second metadata is identified as the same content even though the first content 80-2 corresponding to the first metadata is the same content. There may be cases where this does not work. In this case, a UI 80 in which the first content 80-2 and the second content 80-1 are displayed may be provided, and the user may be exposed to the same content overlappingly, which may reduce satisfaction. .

Meanwhile, according to an example, the second content 80-1 corresponding to the second metadata is the first content corresponding to the first metadata based on the program information, broadcasting operator information, and broadcasting channel information included in the metadata. When the same content (80-2) is identified, as shown in the lower diagram of FIG. 8, the processor 130 determines that the first content (80-2) and the second content (80-1) identified as the same content are single content. The UI 800 indicated by 810 can be provided.

In this case, according to one example, if the identified first content 80-2 and second content 80-1 include different broadcast operator information or broadcast channel information, the processor 130 A UI 800 containing information about a single content 810 and broadcaster information 810-1 and 810-2 corresponding to each content can be provided. That is, the processor 130 may provide a UI that includes at least one of broadcast operator information or broadcast channel information corresponding to a plurality of contents identified as the same content.

Accordingly, users can select content by considering broadcasting operator or broadcasting channel information, and user satisfaction can be improved.
