Description

  The present invention relates to a playback apparatus, a playback method, and a computer program for generating and playing back content in accordance with information from a network device connected via a network, for example.

  In recent years, the development of AV devices and white goods that can communicate with networks has been progressing. As a protocol for controlling such network devices, UPnP (Universal Plug and Play), ECHONET (registered trademark), and the like are standardized. Network-compatible digital TVs are also appearing, and home networks are spreading.

  On the other hand, diversification of content provision forms is progressing. For example, in a normal television program broadcast form, a user views content in a form in which a program broadcast at that time is selected from a limited channel. On the other hand, in VoD (Video on Demand), a user selects a content of interest from a vast amount of content prepared on a server on the Internet or the like at a desired time for viewing. Similarly, there is a form in which a program is recorded and stored by a program automatic recording device in a home, and the user selects content from the program and views it. In addition to explicitly specifying and viewing the content that the user is interested in, a recording device that presents the user's preferred “recommended program” based on the genre, series, etc. of the program that the user has viewed in the past Many have also appeared.

  As one of the technologies using a playback device that plays back these contents and network devices in the home network, the user views the content with the playback device so that the user can quickly and accurately notify the notification information from the network devices. A method of displaying the contents of the notification information on a display screen is disclosed.

  For example, Patent Document 1 discloses a system that displays on a television a notification of completion of dewatering (occurrence of state change) from a washing machine. In particular, in Patent Document 1, in order to prevent a problem that the user is absorbed in watching TV programs (contents viewing), the dehydration end notification is intentionally overlooked (ignored), and as a result, wrinkles can be formed on the laundry. Refers to an operation of adjusting the dehydration end time by controlling the dehydration start time in consideration of the end time of the program being viewed.

However, in the technique disclosed in Patent Document 1, for example, if it starts immediately, a dehydration operation that is originally completed after 10 minutes may be completed after 1 hour to adjust the dehydration start time. sell.
JP 2006-288853 A

  As described above, in the conventional system for displaying the notification information of the network device while viewing the content, the network device side is adjusted with the content playback end time fixed, and therefore there is an extra waiting time in the network device. Time has occurred.

  Therefore, the present invention makes it possible to perform content playback and notification of occurrence of a state change in the network device so as not to cause an extra waiting time in the network device and to prevent intentional oversight by the user.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 shows a playback apparatus (player) 11 according to the first embodiment, a network device 31 that communicates with the playback apparatus 11 via a network, a scenario database 41, a resource database 51, and a video from the playback apparatus 11. The configuration example of the entire system including a display device 61 that receives and displays a signal is shown.

  The content assumed in the present embodiment is one in which “resources” such as video, audio, images, and text are displayed according to “scenarios” that define playback methods such as display position and display timing. However, the present invention is not limited to this, and various forms of content can be targeted.

  The playback device 11 acquires a scenario and a resource from the scenario database 41 and the resource database 51 through network communication and performs playback.

  For example, in the case of Web content, an HTML file is a scenario, a video file such as AVI, an image file such as JPEG, a text file such as RSS (XML format that describes metadata such as Web site update information) Is a resource.

  In particular, in the present embodiment, it is assumed that the scenario includes a flow of time such as designation of a display period of an image file. Known technical specifications include SMIL (Synchronized Multimedia Integration Language), HTML + TIME, and the like. In SMIL and HTML + TIME, a scenario description with a time designation such as “display image A for 25 minutes and then display image B for 10 minutes” can be performed using a description language such as XML.

  In addition, a scenario description including a complicated process such as “analyze an XML tag included in RSS and display its contents in order of 5 minutes in order for every 10 minutes” by a script description language such as ECMAScript is also possible.

  In the present embodiment, it is assumed that in addition to such description designation, it is possible to designate effects (n-times speed reproduction, fade-in / fade-out) for each resource. Further, as content meta information, data such as names, genres, and keywords indicating the contents, and the length of the content (the time taken from the start to the end when the content is reproduced according to the scenario) are also included as data.

  The network device 31 is connected to the playback device 11 via a communication network such as a home network. For example, UPnP or ECHONET can be used as a network protocol for communication between the playback device 11 and the network device 31. The playback device 11 and the network device 31 are physically connected by wired such as Ethernet (registered trademark), USB, IEEE1394, or wirelessly such as 802.11a / b / g, Bluetooth.

  In response to a request from the playback device 11, the network device 31 receives state change contents scheduled to occur in the future, and state change occurrence scheduled time information indicating the time until the state change occurs or the state change expected time. Has the function to provide. For example, in the ECHONET compatible washing machine, the current laundry transition state (washing, rinsing, dehydration, etc.) and the remaining time can be acquired by ECHONET communication. For this reason, the reproduction apparatus 11 can know in advance information such as “dehydration of the washing machine is completed after 30 minutes”.

  The display device 61 is a device such as a television that displays the content played back by the playback device 11. The playback device 11 and the display device 61 may be directly connected by a predetermined AV cable or may be connected via a communication network such as a home network.

  The scenario database 41 detects a scenario that matches the search request condition from the playback device 11 and provides the scenario to the playback device 11. As a search condition, not only the genre and the keyword but also the length of the content can be specified.

  The resource database 51 provides resources such as image files requested from the playback apparatus 11.

  The scenario database 41 and the resource database 51 may exist on the Internet like VoD, or may exist in the same home network as the playback device 11 like a recording device. Moreover, even if it exists physically in the same point, it may exist in another point. These are constructed as Web servers that accept, for example, HTTP requests and return scenario and resource files as responses.

  FIG. 2 is a flowchart showing the operation of the playback apparatus 11 according to the embodiment of the present invention.

  As a situation, a situation is assumed in which a certain user tries to close the idle time by viewing some appropriate content until the washing machine is completely dehydrated. Since the user is not trying to view the specific content, the user thinks that it is sufficient if the content for killing time is automatically reproduced.

  First, a case will be described in which content having a length corresponding to the time until dehydration is completed or content having a shorter length is found. The length according to the time to completion of dehydration is, for example, the same or substantially the same length as the time to completion of dehydration. If the time to completion of dehydration is α, the substantially same range is, for example, α− It can also be represented by β1 to α + β2. In this case, a length shorter than the length corresponding to the time until the dehydration is completed can refer to a length shorter than α-β1, for example. Further, the length exceeding the length corresponding to the time until the dehydration is completed can indicate a length longer than α + β2, for example. β1 and β2 are real numbers of 0 or more, and may be the same or different.

  First, the user operates a device (not shown) such as a remote controller in order to notify the playback device 11 that the user wants to view the content.

  The request reception unit 21 determines that “the user wants to view the content” by detecting a signal from the remote controller (S201). When the request receiving unit 21 detects a signal from the remote controller, the request receiving unit 21 notifies the communication unit 22 of the signal.

  The communication unit 22 communicates with the network device 31 connected to the playback apparatus 11 via a network (S202). Through the communication, the state change contents scheduled to occur in the network device 31 and the time until the occurrence are acquired from the network device 31. Here, it is assumed that an ECHONET compatible washing machine is assumed as the network device 31 and data “dehydration completed” as the state change content and “30 minutes” as the time until occurrence are acquired by ECHONET communication.

  The communication unit 22 stores the “dehydration complete” information in the state change content storage unit 23, and informs the search unit 24 of the time “30 minutes” until the occurrence (S203). For example, in the standard specification of a washing machine in ECHONET, it is defined that EPC (ECHONET Property Code) = 0xE1, DATA = 0x43 represents a dehydrated state, and EPC = 0xE6, DATA = 0x1E represents a remaining time of 30 minutes. However, here, it is assumed that the communication unit 22 has in advance data corresponding to the values (character display information, etc.) and the meaning of each value such that DATA = 0x43 is “dehydration”. .

  The search unit 24 requests the scenario database 41 to search for a scenario using the received “30 minutes” as a search request condition (S204). The scenario database 41 searches for a scenario in which the length of content is 30 minutes, approximately 30 minutes, or less than this, and returns it if found. The search unit 24 stores the scenario received from the scenario database 41 in the scenario storage unit 25 (S205). The scenario storage unit 25 notifies the playback unit 26 that a scenario has been found. The search unit 24 includes, for example, content generation means, first connection means, and second connection means of the present invention.

  The playback unit 26 reads the scenario stored in the scenario storage unit 25, interprets it, and plays back the content (S206). That is, the playback unit 26 communicates with the resource database 51 to acquire and play back resources specified in the scenario as needed. The display is performed on the display device 61. If the content found in S205 has a length of time (30 minutes or approximately 30 minutes) according to the time until dehydration, the story is completed in 30 minutes or approximately 30 minutes, and playback ends (YES in S207). When the reproduction is completed, the reproduction unit 26 performs notification of “dehydration completion”, which is information stored in the state change content storage unit 23, by character display or the like (S208). The reproduction unit 26 includes, for example, reproduction means, presentation means, and third connection means of the present invention.

  If the content found in S205 is shorter than 30 minutes or approximately 30 minutes, it is detected in S207 that “currently reproduced content has ended”, and then the process returns to S204 to repeat the same processing. For example, when the content of “25 minutes” is found in S205 and the user has finished viewing the content, for example, the content having the remaining 5 minutes, approximately 5 minutes, or a shorter length is searched again. When content with a length of “minute” is found, notification of “dehydration completion” is made when the reproduction of this content is completed. If there is no content with an appropriate length, the content longer than 5 minutes or approximately 5 minutes is reorganized to generate content with a length of 5 minutes or approximately 5 minutes according to another case processing example described later. Then, it may be played back. If the remaining time at the end of the content is less than a predetermined threshold, it may be considered that the dehydration has been completed, and a notification of “dehydration completed” may be sent, or “dehydration is completed in the remaining minutes” Notification may be made.

  In S201, the signal received by the request receiving unit 21 may include not only “the playback button on the remote control is pressed” but also “turned on the TV”, “turned the channel”, and the like. .

  In S202 and S203, if it is found that no state change is planned for the network device 31, any content may be searched and reproduced (S209). Further, in the search at this time and also in the search in S204, other conditions such as a favorite genre and keyword set in advance by the user, a past viewing history tendency, etc. may be taken into consideration.

  In S202, one network device with which the playback apparatus 11 communicates may be designated in advance by the user, or the network device that communicates with all connected network devices and has the closest occurrence time. You may make it.

  In S203, it is also possible to store control data such as “we will go to the network device again to acquire the status change contents” without storing the status change contents themselves in the status change content storage unit 23. In this case, after the 30-minute content playback is completed, communication with the network device is performed, and the state change content acquired at that time is displayed. For example, if dehydration is complete, notify “Dehydration completed”, and if there is a delay during the dehydration process, notify “Dehydration completed in the remaining ○ minutes” or “Dehydration process is delayed”. It may be.

  Alternatively, in S203, the state change content itself is not stored in the state change content storage unit 23, but “the specified network device is accessed when the scheduled occurrence time or a certain time before that, and the state change content to be generated is stored there. Control data “notify the state of change when it occurs” may be stored. For example, when a schedule for occurrence of a status change “There is a visitor after 30 minutes” is received from the schedule management device (network device), “Specify detection of visitor if it is within a certain time before the scheduled visit time. Control data may be stored such that a status change inquiry is sequentially made to the network device, and when it is detected that there is actually a visitor until the end of the content, that fact is displayed.

  In S208, the notification of the status change may be made not only by displaying characters but also by using other means such as playing a sound such as “Dehydration is complete”.

  In the above, a case has been described in which content having a length of time corresponding to the time until dehydration is completed or a length shorter than this is found, but in the following, a case in which such content is not found will be described.

  In S205 of FIG. 2, if the search unit 24 searches the scenario database 41 for a scenario whose content length is 30 minutes or approximately 30 minutes or less, but is not found, the search unit 24 determines that the content is 30 minutes or approximately 30 minutes. Search for scenarios that exceed minutes. Next, the reorganization unit 27 adjusts the scenario to a length of 30 minutes or approximately 30 minutes (S210). The reorganization unit 27 stores the adjusted scenario in the scenario storage unit 25, and thereafter performs content reproduction based on the scenario as in the previous procedure. The reorganization unit 27 includes, for example, content generation means of the present invention.

  The length adjustment is performed by the reorganization unit 27 by shortening the display time of each resource or reducing the number of processing repetitions specified in the original scenario. A specific example of scenario reorganization will be described below with reference to FIGS.

  FIG. 3 shows an example of reorganizing a scenario such as “display image B for 10 minutes after video A is displayed for 25 minutes”. In this case, the content is originally 35-minute content, but the reorganization unit 27 rewrites this into a scenario such as “display image B for 5 minutes after video A is displayed for 25 minutes”, so that the content is 30 minutes. . The image B is a still image, and even if this is shortened from 10 minutes to 5 minutes, there is no significant effect on the content display.

  FIG. 4 is an example in which a scenario such as “analyze an XML tag included in RSS and display the contents in order for 10 minutes in order for 10 minutes” is reorganized. For example, it is a scenario where RSS of news sites is analyzed and news headlines are displayed in order. In this case, the content is originally 50 minutes, but the reorganization unit 27 rewrites the content into a scenario such as “analyze an XML tag included in RSS and display the contents in order for 3 minutes in order of 10”. The content is 30 minutes. Also in this case, the displayed content is text information in the XML tag, and even if one display time is shortened from 5 minutes to 3 minutes, there is no significant influence on the content display. Another modification may be 30 minutes of content by “analyzing XML tags included in RSS and displaying their contents in order for 5 minutes in order of 6”.

  Further, the reorganization unit 27 may add an effect instruction to the scenario to reduce the uncomfortable feeling at the time of content reproduction accompanying such a change in the resource display time. Such an example is shown in FIGS.

  FIG. 5 is an example of reorganizing the same scenario as FIG. 3, such as “Display image A for 25 minutes and then display image B for 10 minutes”. Unlike FIG. 3, the reorganization unit 27 rewrites this into a scenario such as “display video A for 20 minutes at 1.25 × speed and then display image B for 10 minutes”. Since the video A is a moving image, if the display period is shortened as it is from 25 minutes to 20 minutes, the last 5 minutes will disappear. Therefore, an instruction such as “display at 1.25 times speed” is added to the scenario, so that the last scene of the video A is displayed even for 20 minutes.

  FIG. 6 shows an example of reorganizing a scenario such as “3 pieces of music each having a length of 11 minutes are played in order”. I don't want to play music like n-times playback. Therefore, without changing the playback speed, the end of playback of the first song is not set to 11 minutes, which is the original length of the song, but is finished in 10 minutes and rewritten into a scenario for moving to the second song. At this time, in order to prevent content that suddenly switches between songs, fade out the first song from the 10 minute point (slowly decrease the volume) and fade in the second song (slowly increase the volume). An effect instruction such as starting is given to the scenario. That is, adjacent resources are overlapped for one minute, and the crossfade process is performed for the overlapped period. As a result, it is possible to reproduce the shortened content with relatively little discomfort.

  Up to this point, an example has been shown in which the reorganization unit 27 arbitrarily modifies a scenario. However, the scenario includes reorganization policy and restriction information (restriction conditions for using resources). There is also. In the following, an example of revising such a scenario is shown.

  FIG. 7 shows an example of reorganizing a scenario such as “image A is displayed for 5 minutes, moving image 1 for 10 minutes, image B for 5 minutes, moving image 2 for 10 minutes, and image C for 5 minutes in order”. Since the total length is 35 minutes, if the display time of any of images A, B, and C is 0 minutes, it is 30 minutes. At this time, for example, it is assumed that the image A and the image C are images that are necessarily displayed, such as credit information of the content creator. In this case, the content creator attaches restriction information (restriction condition) such as “image A and image C cannot be omitted, and image B can be omitted” to the scenario. In accordance with the restriction information, the reorganization unit 27 rewrites the scenario with a scenario in which the display time of the image B is set to 0 minutes, so that the scenario has a length of 30 minutes.

  The reorganization policy and restriction information (restriction conditions) included in the scenario are not limited to such omission / impossibility. For example, for a certain resource, “if it can be displayed for 10 minutes, it will not be shortened to 5 minutes. If it is not possible, a completely different scenario may be defined in accordance with time, such as “display a substitute image (instead of double-speed playback of a moving image)”.

  3 to 7 show examples in which the search unit 24 searches for a scenario having a length longer than the original desired length, and shortens the scenario. However, the search unit 24 has a shorter length than originally desired. A scenario having a length (for example, 25 minutes) may be searched for and reorganized so that it is extended to a length (for example, 30 minutes) that the reorganization unit 27 originally desires. As an example of extension, it is possible to extend the display time of each resource, increase the number of processing repetitions, add resources, or reduce the display speed. In addition to extending a single scenario, for example, the search unit 24 searches for a scenario having a length of 25 minutes and 5 minutes, and the reorganization unit 27 connects it to a new scenario having a length of 30 minutes. It is good also as.

(Second Embodiment)
In the first embodiment, an example is shown in which a scenario is searched and reorganized when a user starts viewing content. Since the scenario is interpreted at any time according to the time designation by the playback unit 26, the scenario may be dynamically changed from the middle. In this embodiment, an example in which a scenario is reorganized in the middle of such content reproduction is shown.

  FIG. 8 is a flowchart showing an operation flow of the playback apparatus according to the present embodiment. The block diagram of the playback apparatus according to the present embodiment is the same as that in FIG. 1, and only the extended processing will be described below.

  It is assumed that the user is viewing a certain content having a length of 50 minutes (S801). The communication unit 22 periodically communicates with the network device 31 connected to the playback device 11 (S802), and checks whether there is a plan for occurrence of a state change (S803). Here, it is assumed that a state change schedule such as “dehydration is completed in 15 minutes” is added when, for example, another user operates the washing machine when viewing for 15 minutes.

  The playback unit 26 calculates whether or not the scenario stored in the scenario storage unit 25 and currently being played back is completed in the time until the state change occurs (S804). Here, since the scenario originally has a length of 50 minutes, if it is left as it is, dehydration completion occurs during content reproduction. Therefore, the reorganization unit 27 rewrites the remaining part after the scenario part that has been interpreted up to that point so as to have the same or substantially the same length as the remaining time until the occurrence of the state change (S805).

  FIG. 9 shows an example of such dynamic reorganization. In this example, in a scenario having an original length of 50 minutes, “Display up to 10 texts in sequence for 5 minutes”, when 15 texts are displayed and up to 3 texts are displayed, the remaining 7 texts are 15 In order to display in minutes, it is rewritten as “display every 2 minutes”.

  After the rewriting, the playback unit 26 continues to play back the content. When the playback ends (YES in S807), the “dehydration complete” notification, which is information stored in the state change content storage unit 23, is displayed as text or the like. (S808).

  As described above, according to the above-described embodiment, the content can be reorganized in accordance with the scheduled time of occurrence of the state change from the network home appliance and presented to the user. Therefore, when the user has just finished viewing the content, You can know the state change information from. Since the content has already ended, the notification such as completion of dehydration is ignored and the content is not continued to be viewed.

  The processing of this embodiment can also be applied to the first embodiment. In other words, in the first embodiment, once the network device is notified of the scheduled change occurrence time, the content is only generated and played back according to the planned time. However, depending on the network device, the initial scheduled time is advanced. Or a situation such as slowness is assumed. When such a change notification is acquired from the network device, the scenario may be rewritten according to the scheduled time after the change according to the present embodiment.

  Note that the playback device described above can also be realized by using, for example, a general-purpose computer device as basic hardware. That is, the request reception unit, the communication unit, the reorganization unit, the search unit, and the playback unit in the playback device can be realized by causing a processor mounted on the computer device to execute a program. At this time, the playback apparatus may be realized by installing the above program in a computer device in advance, or may be stored in a storage medium such as a CD-ROM, or distributed through the network. The program may be implemented by appropriately installing it in a computer device. In addition, the scenario storage unit and the state change content storage unit appropriately include a memory, a hard disk or a storage medium such as a CD-R, a CD-RW, a DVD-RAM, a DVD-R, or the like incorporated in or externally attached to the computer device. It can be realized by using.

  Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
