Specifically, the photographing control unit 112 receives the address (IP) information of the client terminal through the first communication unit 111. Here, the first communication unit 111 may be a wireless communication module as a configuration for data communication with the management terminal 130. Here, the IP information of the client terminal may be the address information of the client terminal 120 that wants to view the broadcast content provided by the shooting terminal 110, and is hereinafter referred to as the view client IP information.

For example, when an input signal for using the photographing function is received through the operation of the photographer and the photographing function of the photographing terminal 110 is activated, the photographing control unit 112 receives the viewing client IP information through the first communication unit 111 can do. Alternatively, the photographing control unit 112 may acquire the viewing client IP information from the management terminal 130 via the first communication unit 111 before storing the photographing function in the separate memory.

The photographing control unit 112 can acquire at least one viewing client IP information through the first communication unit 111. [ A plurality of client terminals 120 to view the broadcast content provided by the shooting terminal 110 may be a plurality (n), and the shooting control unit 112 may acquire a plurality of viewing client IP information through the first communication unit 111 Can be obtained.

In this specification, it is assumed that the photographing control unit 112 obtains at least one viewing client IP information from the management terminal 130 via the first communication unit 111 when the photographing function of the photographing terminal 110 is activated.

The photographing control unit 112 attempts to pair (connect) with the client terminal 120 having the viewing client IP obtained through the first communication unit 111 so that the client terminal 120 ) Can be directly communicated. If a plurality of (n) pieces of viewing client IP information are acquired through the first communication unit 111, the photographing control unit 112 acquires a plurality of (n) client terminal 120 corresponding to the viewing client IP, Pairing can be connected to the communication.

In addition, when the photographing function is activated, the photographing control unit 112 collects photographing image data for the broadcast contents through the image photographing unit 113. Here, the image capturing unit 113 includes an image sensor that captures an image captured through a lens and converts the captured optical signal into an electrical signal, a signal processing module that converts an analog image signal captured by the image sensor into digital data, . Here, the image sensor may be a CCD (Charge Coupled Device) sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor, and the signal processing module may be implemented by a DSP (Digital Signal Processor), but the present invention is not limited thereto.

The photographing control unit 112 broadcasts photographed image data collected through the image photographing unit 113 to the client terminal 120 through the image transmitting unit 114. [ Here, the video transmitting unit 114 may include a broadcast content transmission solution, and may include a communication module supporting wireless communication with the client terminal 120. [

The photographing control unit 112 may transmit the photographed image data collected through the image photographing unit 113 to the client terminal 120 in real time through the image sending unit 114. [ When the photographing function is activated, the photographing control unit 112 transmits the photographed image data of the image photographed by the photographing unit 113 through the image transmitting unit 114 and transmits the photographed image data to the client terminal 120 do. As another example, when an input signal for using the transmission function is separately received and the transmission function is activated in a state in which the photographing function is activated, the image capturing control unit 112 controls the image capturing unit 113 And transmits the captured image data to the client terminal 120 in real time via the image transmission unit 114. [

If the plurality of (n) client terminals 120 are communicatively connected to each other, the image capturing control unit 112 simultaneously captures the plurality of (n) client terminals 120 communicated through the image transmitting unit 114, Video data can be transmitted.

The photographing control unit 112 may transmit the photographed image data to the management terminal 130 as occasion demands.

Meanwhile, the shooting terminal 110 does not perform a separate encoding operation on the photographed image data, and transmits photographed image data of a file format (format) supported by the photographing terminal 110 among all image file formats such as MP4, To the terminal 120.

When the broadcasting is activated (photographing function activation, transmission function activation, or separate operation input by the photographer), the photographing control section 112 transmits category information on the broadcast contents provided by the photographing terminal 110 to the first communication section 111 to the management terminal 130. Here, the category information on the broadcast content may be information on any one of a plurality of folder format categories managed by the management terminal 130.

The category of the broadcast content of the shooting terminal 110 may be set by the photographer or the category may be automatically set according to the category information of the previously taken broadcast content. For example, the category information may include at least one of a main category, an intermediate category located under the main category, and sub category information located under the sub category. Alternatively, if there is no corresponding category information, category information for creating a new category may be transmitted to the management terminal 130, so that the management terminal 130 can create a folder for the new category.

In this way, the shooting terminal 110 obtains the IP information of at least one client terminal 120 that wants to view its broadcast content from the management terminal 130, and transmits the IP information of the client terminal 120 to the client terminal 120 based on the obtained IP information. And transmits the captured image data to the client terminal 120. The management terminal 130 can transmit the category information for the broadcast content.

Hereinafter, the operation of the client terminal according to the embodiment of the present invention will be described in detail with reference to FIG.

3 is a configuration block diagram of a client terminal according to an embodiment of the present invention.

3, the client terminal 120 includes a second communication unit 121, a client control unit 122, an image receiving unit 123, a video encoding unit 124, and a screen display unit 125.

The client control unit 122 may be a microcontroller unit (MCU) for controlling overall functions of the client terminal 120.

The client control unit 122 may transmit information on whether to receive the broadcast content provided by the shooting terminal 110 to the management terminal 130 through the second communication unit 121. [ Here, the second communication unit 121 may be a wireless communication module as a configuration for data communication with the management terminal 130.

If the client (user) is selected to view any one of the broadcast contents of the category managed by the management terminal 130 due to the operation of the client terminal 120 of the client (user) And transmits broadcast content viewing request information including address (IP) information (viewing client IP information) to the management terminal 130 through the second communication unit 121. [ For example, the client terminal 120 may include a real-time broadcast application (application program, APP) for a real-time broadcast system. When a real-time broadcast application is executed by the operation of a client and broadcast content to be viewed is selected, The broadcast content viewing request information including the client IP information may be transmitted to the management terminal 130. [

The viewing client IP information transmitted to the management terminal 130 may be transmitted to the photographing terminal 110 providing the broadcast content desired to be viewed by the client. In this manner, as the viewing client IP information is transmitted to the shooting terminal 110 that provides the broadcast content to be viewed, the shooting terminal 110 receiving the viewing client IP information transmits the viewing client IP information to the client terminal 120 to establish a communication connection (pairing). At this time, the communication connection request information of the photographing terminal 110 may be received through the image receiving unit 123. [

The client terminal 120 and the photographing terminal 110 providing the broadcast contents desired to be viewed by the client can be communicatively connected and the client control unit 122 controls the photographing terminal 110 through the image receiving unit 123, It is possible to directly receive the photographed image data sent out from the camera.

The client control unit 122 receives the photographed image data of the photographing terminal 110 through the image receiving unit 123. [ At this time, the client control unit 122 transmits the photographed image data as it is, without being encoded, to a file format format (for example, MP4 or the like) photographed by the photographing terminal 110, Lt; / RTI >

When a plurality of client terminals 120_1 to 120_n request reception of the same broadcast content, the client terminal 120 may acquire the captured image data transmitted from the corresponding shooting terminal 110 Can be transmitted in real time to all of the plurality of client terminals 120_1 to 120_n through one-to-many (1: n) direct communication.

The client control unit 122 displays the photographed image data received through the image receiving unit 123 through the screen display unit 125 on the screen. At this time, the screen display unit 125 may be a display module implemented in the client terminal 120 or a separate display device connected to the client terminal 120.

At this time, the screen display unit 125 displays and reproduces the shot image data received through the image receiving unit 123 in real time, so that the client can watch the broadcast content provided by the shooting terminal 110 in real time.

In addition, the client control unit 122 controls the image encoding unit 124 to encode the image data received through the image receiving unit 123. At this time, the image encoding unit 124 may encode the photographed image data received through the image receiving unit 123 to generate encoded image data.

In order to encode the photographed image data, it is necessary to use the H.264, H.265, RTSP (Real Time Streaming Protocol), RTMP (Real Time Messaging Protocol), MPEG-TS (Moving Picture Experts Group- An encoding codec capable of compressing and converting a file format can be used. Preferably, the image encoding unit 124 may perform an encoding operation on the photographed image data using an encoding codec set by the developer or the operator in advance.

On the other hand, when there are a plurality of client terminals 120 that view the broadcast content provided by the shooting terminal 110, each of the plurality of client terminals 120_1 to 120_n can encode the received shot image data. At this time, the encoding codec used in each of the plurality of client terminals 120_1 to 120_n is formatted, and each of the plurality of client terminals 120_1 to 120_n can encode the photographed image data using the same encoding codec.

That is, the photographed image data received from each of the plurality of client terminals 120_1 to 120_n is recorded in the same file format (extension), the same image size (resolution), the same bit rate and the same frame rate per second (fps) To be RAW DATA. For example, the extension of the encoded image data generated by the video encoding unit 124 of each of the plurality of client terminals 120_1 to 120_n may be avi, the image size may be 850x480, the bit rate may be 800, and 60 frames per second .

The client control unit 122 transmits the encoded image data generated by encoding by the image encoding unit 124 to the management terminal 130 through the second communication unit 121. At this time, the client control unit 122 transmits the encoded image data corresponding to the transmission frame allocated from the management terminal 130 to the management terminal 130. Here, a transmission frame allocated to each of the plurality of client terminals 120_1 to 120_n may be allocated based on the number of client terminals connected to the shooting terminal 110 and data communication. Alternatively, a transmission frame allocated to each of the plurality of client terminals 120_1 to 120_n may be allocated based on the number of client terminals connected to the management terminal 130 and data communication.

Preferably, a transmission frame allocated according to an embodiment of the present invention may be allocated based on the number of client terminals connected to both the shooting terminal 110 and the management terminal 130 and the data communication. Accordingly, each of the plurality of client terminals 120_1 to 120_n can transmit encoded image data of different frames to the management terminal 130 for the same broadcast content.

For example, when three client terminals (first to third client terminals) 120_1 to 120_3 receive photographed video data from the shooting terminal 110, and the video encoding units 124_1 to 120_3 of the three client terminals 120_1 to 120_3 ), It is assumed that encoded image data having 60 frames per second is generated.

In this case, each of the plurality of client terminals 120_1 to 120_n may be assigned transmission frames of the same size. For example, the transmission frame allocated to the first client terminal 120_1 is 1 frame to 20 frames, the transmission frame allocated to the second client terminal 120_2 is 21 frames to 40 frames, based on 60 frames per second , And the transmission frame allocated to the third client terminal 120_3 may range from 41 frames to 60 frames. At this time, the allocated transmission frame can be sequentially allocated according to the pairing order between the client terminal 120 and the management terminal 130, and the allocated transmission frame and period can be set in advance.

Accordingly, the first to third client terminals 120_1 to 120_3 can sequentially transmit the encoded image data of the frame allocated to the client terminal 120_1 to the management terminal 130. [ For example, the first to third client terminals 120_1 to 120_3 may transmit 20 frames of encoded image data to the management terminal 130 every second.

In addition, the allocated transmission frame can be changed from time to time according to the data communication connection state of the client terminal 120. [ If at least one client terminal 120 among a plurality of client terminals 120_1 to 120_n is disconnected from the management terminal 130 or the photographing terminal 110, It is possible to sequentially transmit the allocated transmission frame.

For example, when the first to third client terminals 120_1 to 120_3 transmit the 20 frames of the encoded image data having 60 frames per second to the management terminal 130 and the encoded image data of 5 seconds is transmitted, It is assumed that the data connection of the terminal 120_2 is disconnected.

In this case, after the data connection of the second client terminal 120_2 is disconnected, the first client terminal 120_1 transmits encoded image data of 1 frame to 20 frames from 5 seconds to 6 seconds to the management terminal 130 The third client terminal 120_3 transmits encoded image data of 21 frames to 40 frames between 5 seconds and 6 seconds to the management terminal 130 and the first client terminal 120_1 transmits the encoded image data of 5 to 6 seconds To the management terminal 130. The third client terminal 120_3 transmits the encoded image data from 1 frame to 20 frames between 6 seconds and 7 seconds to the management terminal 130, (130).

In this manner, the client terminals other than the client terminal whose data connection is disconnected can sequentially transmit the encoded image data to the management terminal 130. Each of the plurality of client terminals 120_1 to 120_n transmits the encoded image data for the sequentially assigned transmission frames so that the management terminal 130 can receive the completely encoded image data having 60 frames per second.

In addition, the client control unit 122 can change the environment of the user interface (UIX) of the real-time broadcast application provided to the client. For example, when the user interface change request is inputted through the operation of the client, the client control unit 122 can transmit a user interface change request to the management terminal 130 through the second communication unit 121. [ For example, the client control unit 122 can change (modify) the category of the broadcast content provided by the management terminal 130 according to the operation of the client. At this time, it is possible to change at least one of the major category, the middle category, and the sub category of the category of the broadcast content managed by the management terminal 130. For this, the management terminal 130 may store category information for each client terminal.

For example, it is assumed that the category of the broadcast content provided by the photographing terminal or the broadcast provider by the photographing terminal 110 is set as 'major category-Internet lecture, middle category-high category, and small category-repair area'.

At this time, the client control unit 122 may change the category of the broadcast content managed by the management terminal 130 to the 'major category-Internet lecture, middle category-mathematics, small category-first rank' through the operation of the client. Alternatively, through the operation of the client, the client control unit 122 newly generates a category of the broadcast content managed by the management terminal 130, and transmits the category of the broadcast content to the lecture of the lecture-OOO instructor, the middle class, The category of the broadcast content can be changed to the "sub-category 2-repair area".

In this manner, the client terminal 120 receives and displays the captured image data of the broadcast content transmitted from the photographing terminal 110 through the streaming technique so that the client terminal 120 can view the captured image data, and the encoded image data The video data can be transmitted to the management terminal 130 so that the broadcast content can be managed by the management terminal 130 and the category of the broadcast content managed by the management terminal 130 can be changed and created.

Hereinafter, the operation of the management terminal according to the embodiment of the present invention will be described in detail with reference to FIG.

4, the management terminal 130 includes a third communication unit 131, a management control unit 132, an image processing unit 133, and a broadcast content storage unit 134.

The management control unit 132 may be a micro controller unit (MCU) for controlling overall functions of the management terminal 130.

Specifically, the management control unit 132 receives broadcast content viewing request information from the client terminal 120 through the third communication unit 131. [ Here, the third communication unit 131 may be a wireless communication module as a configuration for data communication with the shooting terminal 110 and the client terminal 120, respectively.

The management control unit 132 may receive the broadcast content viewing request information including the IP information (viewing client IP information) of the client terminal 120 that wants to view the broadcast content through the third communication unit 131. [ The management control unit 132 receives the broadcast content viewing request information from the client terminal 120 through the third communication unit 131 and displays the broadcast content viewing request information to the photographing terminal 110 providing the broadcast content that the client terminal 120 wants to view And transmits the client IP information. If the viewing request information for the broadcasting contents provided by any one of the photographing terminals 110 is received from the plurality of client terminals 120_1 to 120_n, the management control unit 132 transmits the viewing client IP to the third communication unit 131 to the photographing terminal 110.

In addition, the management control unit 132 manages the connection state between the client terminal 120 and the photographing terminal 110. For example, the management control unit 132 frequently checks whether or not communication connection is disconnected between the client terminal 120 and the photographing terminal 110 corresponding to the viewing client IP. If a plurality of client terminals 120_1 to 120_n view the broadcast content provided by any one of the photographing terminals 110, the management control unit 132 controls the plurality of client terminal apparatuses 120_1 to 120_n and the photographing terminal 110 can be checked at any time.

If the connection state between the client terminal 120 and the photographing terminal 110 is stable, the management control unit 132 transmits the encoded image data of the broadcast content to be provided to the photographing terminal 110 to the client terminal 120 via the third communication unit 131, (120). When a plurality of client terminals 120_1 to 120_n view any one of the broadcast contents, the management control unit 132 controls the plurality of client terminals 120_1 to 120_n according to the number of the client terminals 120_1 to 120_n, A transmission frame may be allocated to each of the client terminals 120_1 to 120_n to receive encoded image data of different frames for the same broadcast content.

If a plurality of client terminals 120_1 to 120_n watch one of the broadcast contents, the management control unit 132 allocates an allocated transmission frame in the order of communication with each of the plurality of client terminals 120_1 to 120_n can do. At this time, the communication connection order may be the order in which the broadcast content viewing request information is received.

The three client terminals 120_1 to 120_3 receive photographed video data from the shooting terminal 110 and the video encoding unit 124 of each of the three client terminals 120_1 to 120_3 It is assumed that encoding image data having 60 frames per second is generated.

At this time, the management controller 132 may allocate transmission frames of the same size to each of the plurality of client terminals 120_1 to 120_n. For example, the management control unit 132 assigns a transmission frame of 1 to 20 frames to the first client terminal 120_1 and transmits 21 to 40 frames to the second client terminal 120_2 on the basis of 60 frames per second Frame, and allocates a transmission frame of 41 to 60 frames to the third client terminal 120_3. At this time, the allocated transmission frames can be sequentially allocated to the client terminal 120 according to the pairing order, and the allocated transmission frames and periods can be set in advance.

Accordingly, the management control unit 132 can sequentially receive the encoded image data of the assigned transmission frame from the first to third client terminals 120_1 to 120_3 through the third communication unit 131. [ For example, the management control unit 132 may receive 20 frames of encoded image data every second from each of the first to third client terminals 120_1 to 120_3.

In addition, the management control unit 132 may change the transmission frame allocated to the plurality of client terminals 120_1 to 120_n at any time according to the data communication connection state with the client terminal 120. [ If the data connection between at least one of the client terminals 120_1 to 120_n and the client terminal 120 or the photographing terminal 110 is disconnected from the plurality of client terminals 120_1 to 120_n, It is possible to allocate the allocated transmission frame to the client terminal and receive the allocated transmission frame sequentially from the remaining client terminals 120. [

For example, in a state where encoded image data of 5 seconds is received for 20 frames out of the encoded image data having 60 frames per second from the first to third client terminals 120_1 to 120_3, It is assumed that the data connection of the terminal 120_2 is disconnected.

In this case, after the data connection of the second client terminal 120_2 is disconnected, the management control unit 132 transmits the encoded video data of 1 to 20 frames between 5 seconds and 6 seconds to the first client terminal 120_1 And assigns a transmission frame to the third client terminal 120_3 so as to transmit encoded image data of 21 to 40 frames between 5 seconds and 6 seconds. Then, the first client terminal 120_1 allocates a transmission frame from 5 seconds to 6 And transmits the encoded image data of 1 to 20 frames between 6 seconds and 7 seconds to the third client terminal 120_3 by allocating a transmission frame to transmit the encoded image data of 41 to 60 frames do. Accordingly, the management control unit 132 can sequentially receive the encoded image data from the remaining client terminals except for the client terminal whose data connection is disconnected. To the management terminal (130).

Through the above process, the management control unit 132 receives the encoded image data for the transmission frames sequentially allocated from each of the plurality of client terminals 120_1 to 120_n, thereby obtaining the completely encoded image data having 60 frames per second .

In addition, the management control unit 132 may transmit the encoded image data received by the client terminal 120 disconnected from the communication connection. For example, after the communication connection of the second client terminal 120_2 is disconnected, the management control unit 132 transmits encoded video data of 1 to 20 frames, which is received from the first client terminal 120_1, Transmits encoded image data of 21 to 40 frames between 5 seconds and 6 seconds received from the third client terminal 120_3 to the second client terminal 120_2, Transmits encoded image data of 41 to 60 frames between 5 seconds and 6 seconds received from the terminal 120_1 to the second client terminal 120_2 and transmits encoded image data of 6 to 7 seconds received from the third client terminal 120_3 To the second client terminal 120_2, encoded image data of 1 to 20 frames.

Accordingly, the second client terminal 120_2 disconnected from the communication connection can display the encoded video data received from the management terminal 130, thereby providing the broadcast content provided by the shooting terminal 110 without interruption to the client .

The management control unit 132 can process the encoded video data of the broadcast content received from the plurality of client terminals 120_1 to 120_n through the video processing unit 133 to generate broadcast content data. At this time, the image processor 133 may generate a plurality of encoded video data received from the plurality of client terminals 120_1 to 120_n that watch the same broadcast content, as one broadcast content data by arranging them in time and frame order . For example, the image processing unit 133 sequentially combines transmission frames received for 20 frames from the plurality of client terminals 120_1 to 120_n to generate complete broadcast content data.

In addition, the management control unit 132 stores the broadcast content data generated by the video processing unit 133 in the folder of the corresponding category of the broadcast content storage unit 134. [ At this time, the broadcast content storage unit 134 may store the broadcast content data according to predetermined categories, and may be a large capacity server.

Here, the folder of the category for the broadcast content data may be set according to the category information received from the shooting terminal 110. For example, when an arbitrary category is set in the category information received from the shooting terminal 110, the management control unit 132 stores the broadcast content data in the folder of the category. If no category is set in the category information received from the shooting terminal 110, a new category and a folder for the new category are created, and the broadcast content data is stored in the created new folder.

In addition, the client-specific user interface information may be stored in the broadcast content storage unit 134 or in a separate memory. The management control unit 132 can change and delete the category of the category of the broadcast content data, the category of the middle class that belongs to the major category, and the category of the middle class that are classified based on the user interface change information received from the client terminal 120.

For example, it is assumed that the category of the broadcast content received from the photographing terminal 110 is category information set as 'major category-Internet lecture, middle category-high category, and small category-repair area'.

At this time, if a category change request for the broadcast content is received from the client terminal 120, the management control unit 132 changes the category of the broadcast content according to the received category change request, and stores the broadcast content data in a folder of the changed category Can be moved. For example, when the client terminal 120 is requested to change the category of the broadcast content from "main category - Internet lecture, middle category - mathematics, small category - first lecture", the management control part 132 ' Math, small category, first class' category information. Alternatively, if the category of the broadcast content is requested from the client terminal 120 to create a new category as "main category - OOO lecturer, middle class - competence against the test, sub category 1 - 3 mockery solving, sub category 2 - The management control unit 132 moves the broadcast content data stored in the other folder to a folder having category information of 'lecture-class lecture, classroom lecture-lecture performance, small class 1 - 3 mockery solving, small class 2 - .

In this manner, the management terminal 130 manages the communication connection state between the client terminal 120 and the shooting terminal 110, and divides the encoded video data for one broadcast content into a plurality of client terminals 120_1 to 120 - And the received encoded video data is collected and stored as one piece of broadcast content data to construct a broadcast content database. In addition, the management terminal 130 can manage a plurality of broadcast contents by predetermined categories, and can store broadcast content data for a plurality of broadcast contents in a folder to construct a broadcast content database.

Furthermore, the real-time broadcasting system according to the embodiment of the present invention may further include a cloud server. The cloud server can confirm the address (IP) of the management terminal 130 and manage the IPs of the plurality of client terminals 120_1 to 120_n connected to the management terminal 130. [ At this time, the cloud server can manage the IP information of the plurality of management terminals 130 and the IP information of the plurality of client terminals 120_1 to 120_n connected to the plurality of management terminals 130, respectively. This is because the management terminal 130 and the client terminal 120 use the floating IP for the communication connection.

If the IP of at least one of the plurality of management terminals 130 and the plurality of client terminals 120_1 to 120_n is changed, the cloud server receives and stores the changed IP information from the management terminal 130. [

As described above, according to the embodiment of the present invention, the photographed image data of the broadcast content photographed by the photographed terminal is directly transmitted to each of the plurality of client terminals in real time, and the photographed image data received from each of the plurality of client terminals is outputted The client can watch the broadcast content provided by the shooting terminal in real time.

According to the embodiment of the present invention, each of the plurality of client terminals encodes the received shot image data to generate encoded image data without performing an encoding operation on the shot image data at the shooting terminal, The time for providing the broadcast contents to the client can be reduced as compared with a technique in which the server encodes the shot video data and provides the encoded video data to the client terminal.

In addition, according to the embodiment of the present invention, each of the plurality of client terminals transmits encoded image data for a transmission frame assigned to the client terminal to the management terminal, collects a plurality of encoded image data received from the management terminal, It is possible to generate broadcast content data.

5 is a flowchart illustrating an overall operation of a real-time broadcasting system according to an embodiment of the present invention.

First, when the client terminal 120 receives a broadcast content viewing request of any one of a plurality of broadcast contents managed by the management terminal 130 due to the operation of the client (user) (S501) And transmits broadcast content viewing request information including information to the management terminal 130 (S502). For example, the client terminal 120 may include a real-time broadcast application (application program, APP) for a real-time broadcast system. When the real-time broadcast application is executed by the operation of the client and the broadcast content to be viewed is selected, The broadcast content viewing request information including the IP information (viewing client IP information) of the broadcast content viewing request information may be transmitted to the management terminal 130.

Upon receiving the broadcast content viewing request information from the client terminal 120, the management terminal 130 transmits the IP information (viewing client IP information) of the client terminal to view the broadcast content to the shooting terminal 110 (S503). The management terminal 130 may transmit the viewing client IP information to the shooting terminal 110 that provides the broadcast content that the client terminal 120 wants to view.

The imaging terminal 110 receiving the viewing client IP information from the management terminal 130 requests communication connection (pairing) with the client terminal 120 corresponding to the received viewing client IP (S504). At this time, if the number of received viewing client IPs is a plurality (n), the shooting terminal 110 can pair with each of a plurality of client terminals 120_1 to 120_n having a plurality of viewing client IPs for communication connection.

In addition, the shooting terminal 110 captures the broadcast content (S505). When the photographing function is activated by the photographer or the broadcast provider, the photographing terminal 110 photographs the image of the broadcast content desired to be provided by the photographing terminal or the broadcast provider.

The photographing terminal 110 transmits the photographed image data of the photographed broadcast contents to the client terminal 120 (S506). At this time, the photographing terminal 110 can transmit photographed image data for the broadcast contents in real time to the client terminal 120 communicably connected according to the viewing client IP. At this time, the shooting terminal 110 does not perform a separate encoding operation on the photographed image data, and transmits the photographed image data of a file format (format) supported by itself to all of the image file formats such as MP4, Lt; / RTI >

If the number of the client terminals 120 communicating with each other is plural (n), the photographed image data can be transmitted to all of the plurality of client terminals 120_1 to 120_n in real time through one-to-many (1: n) direct communication .

The client terminal 120 displays the photographed image data received from the photographing terminal 110 on the screen (S507). At this time, the client terminal 120 displays and reproduces the shot image data received from the shooting terminal 110 in real time, so that the client can watch the broadcast content provided by the shooting terminal 110 in real time.

In addition, encoded image data is encoded to generate encoded image data (S508). In order to encode the photographed image data, it is necessary to use the H.264, H.265, RTSP (Real Time Streaming Protocol), RTMP (Real Time Messaging Protocol), MPEG-TS (Moving Picture Experts Group- An encoding codec capable of compressing and converting a file format can be used. Preferably, the image encoding unit 124 may perform an encoding operation on the photographed image data using an encoding codec set by the developer or the operator in advance.

 If there are a plurality (n) of client terminals 120 viewing the same broadcast content, each of the plurality of client terminals 120_1 to 120_n may encode the received captured image data. At this time, the encoding codec used in each of the plurality of client terminals 120_1 to 120_n is formatted, and each of the plurality of client terminals 120_1 to 120_n can encode the photographed image data using the same encoding codec.

The management terminal 130 allocates a transmission frame in consideration of the number of the client terminals 120 viewing the broadcast content provided by the shooting terminal 110 in operation S509 and transmits the transmission frame allocated to the client terminal 120 Information is transmitted (S510). The transmission frame allocated according to the embodiment of the present invention can be allocated based on the number of the client terminals 120 connected to both the shooting terminal 110 and the management terminal 130 and the data communication.

If a plurality of client terminals 120_1 to 120_n view any one of the broadcast contents, the management terminal 130 allocates an allocated transmission frame in the order in which the plurality of client terminals 120_1 to 120_n are communicatively connected with the client terminal 120_1 to 120_n can do. At this time, the communication connection order may be the order in which the broadcast content viewing request information is received.

The three client terminals 120_1 to 120_3 receive photographed image data from the photographing terminal 110 and each of the three client terminals 120_1 to 120_3 has 60 frames per second It is assumed that encoded image data is generated.

At this time, the management terminal 130 can allocate transmission frames of the same size to each of the plurality of client terminals 120_1 to 120_n. For example, the management terminal 130 allocates a transmission frame of 1 to 20 frames to the first client terminal 120_1 and transmits 21 to 40 frames to the second client terminal 120_2 on the basis of 60 frames per second Frame, and allocates a transmission frame of 41 to 60 frames to the third client terminal 120_3. At this time, the allocated transmission frames can be sequentially allocated to the client terminal 120 according to the pairing order, and the allocated transmission frames and periods can be set in advance.

In addition, the management terminal 130 may change the transmission frames allocated to the plurality of client terminals 120_1 to 120_n from time to time according to the data communication connection state with the client terminal 120. [ If at least one client terminal 120 of the plurality of client terminals 120_1 to 120_n is disconnected from the data terminal of the client terminal 120 itself or the photographing terminal 110, It is possible to reassign the allocated transmission frame to the client terminal and transmit the transmission frame information allocated to the remaining client terminal 120. [

For example, in a state where encoded image data of 5 seconds is received for 20 frames out of the encoded image data having 60 frames per second from the first to third client terminals 120_1 to 120_3, It is assumed that the data connection of the terminal 120_2 is disconnected.

In this case, after the data connection of the second client terminal 120_2 is disconnected, the management terminal 130 transmits the encoded video data of 1 to 20 frames between 5 seconds and 6 seconds to the first client terminal 120_1 And assigns a transmission frame to the third client terminal 120_3 so as to transmit encoded image data of 21 to 40 frames between 5 seconds and 6 seconds. Then, the first client terminal 120_1 allocates a transmission frame from 5 seconds to 6 And transmits the encoded image data of 1 to 20 frames between 6 seconds and 7 seconds to the third client terminal 120_3 by allocating a transmission frame to transmit the encoded image data of 41 to 60 frames do.

The client terminal 120 transmits the encoded image data of the transmission frame assigned to the client terminal 120 to the management terminal 130 (S511). For example, when three client terminals (first to third client terminals) 120_1 to 120_3 watch broadcast content, the first to third client terminals 120_1 to 120_3 sequentially encode the frame allocated to them And transmits the image data to the management terminal 130. For example, the first to third client terminals 120_1 to 120_3 may transmit 20 frames of encoded image data to the management terminal 130 every second.

Accordingly, the management terminal 130 can sequentially receive the encoded image data of the assigned transmission frame from the plurality of client terminals 120_1 to 120_n.

The management terminal 130 collects a plurality of encoded video data received from the plurality of client terminals 120_1 to 120_n, and generates and stores any one of the broadcast content data using the collected encoded video data (S512).

The management terminal 130 can acquire the fully encoded image data having 60 frames per second by receiving the encoded image data for the transmission frames sequentially allocated from each of the plurality of client terminals 120_1 to 120_n.

Accordingly, the management terminal 130 can process the encoded video data of the broadcast content received from the plurality of client terminals 120_1 to 120_n to generate broadcast content data. At this time, the management terminal 130 may generate a plurality of encoded video data received from the plurality of client terminals 120_1 to 120_n that watch the same broadcast content, as one broadcast content data, in a time and frame order . For example, the management terminal 130 sequentially combines transmission frames received for 20 frames from a plurality of client terminals 120_1 to 120_n to generate complete broadcast content data.

In addition, the management terminal 130 stores the generated broadcast content data in a folder of the corresponding category. At this time, the management terminal 130 may store broadcast content data by predetermined categories. Here, the folder of the category for the broadcast content data may be set according to the category information received from the shooting terminal 110. For example, if an arbitrary category is set in the category information received from the shooting terminal 110, the management terminal 130 stores the broadcast content data in the folder of the category. If no category is set in the category information received from the shooting terminal 110, the management terminal 130 generates a new category and a folder therefor, and stores the broadcast content data in the created new folder.

In addition, the client terminal 120 receives the user interface change request through the operation of the client (S513). When the user interface change request is input, the client terminal 120 transmits the user interface change request information to the management terminal 130 (S514). At this time, the user interface change request information may include category change request information of the broadcast content provided by the management terminal 130. [ For example, the user interface change request information may include information for changing (correcting) at least one of a category major category, a middle class category, and a minor category for the broadcast content managed by the management terminal 130.

The management terminal 130 changes the category of the broadcast content data according to the received user interface change request information (S515). To this end, client-specific user interface information may be stored in a separate memory. The management terminal 130 can change and delete categories of the broadcast content data, the middle class of the large class and the small class of the middle class according to the user interface change information received from the client terminal 120.

For example, it is assumed that the category of broadcast content preset by the photographing terminal 110 is category information set as 'major category-Internet lecture, middle category-high category, small category-repair area'.

At this time, when the category change request for the broadcast content is received from the client terminal 120, the management terminal 130 changes the category of the broadcast content according to the received category change request, and stores the broadcast content data in a folder of the changed category Can be moved. For example, when the client terminal 120 is requested to change the category of the broadcast content from "major category - Internet lecture, middle category - mathematics, small category - first lecture", the management terminal 130 ' Math, small category, first class' category information. Alternatively, if the category of the broadcast content is requested from the client terminal 120 to create a new category as "main category - OOO lecturer, middle class - competency against competence, subcategory 1 - 3 mockery solving, subcategory 2 - The management terminal 130 moves the broadcast content data stored in the other folder to the folder having the category information of 'lecture class, OOO lecturer, middle class, lecture class, small class 1 - 3 mockery solving, small class 2 - .

As described above, according to the embodiment of the present invention, the photographed image data of the broadcast content photographed by the photographed terminal is directly transmitted to each of the plurality of client terminals in real time, and the photographed image data received from each of the plurality of client terminals is outputted The client can watch the broadcast content provided by the shooting terminal in real time.

According to the embodiment of the present invention, each of the plurality of client terminals encodes the received shot image data to generate encoded image data without performing an encoding operation on the shot image data at the shooting terminal, The time for providing the broadcast contents to the client can be reduced as compared with a technique in which the server encodes the shot video data and provides the encoded video data to the client terminal.

In addition, according to the embodiment of the present invention, each of the plurality of client terminals transmits encoded image data for a transmission frame assigned to the client terminal to the management terminal, collects a plurality of encoded image data received from the management terminal, It is possible to generate broadcast content data.
