  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of a content transmission device 11 on the broadcast station side in the multimedia broadcast service described in this embodiment. That is, the content transmission device 11 includes an input terminal 12 to which the content for the above-described real-time broadcasting service is input.

  The content input to the input terminal 12 is subjected to compression processing by a moving picture experts group (MPEG) encoder 13 and subjected to PES processing / sectioning processing by a PES (packetized elementary stream) / sectioning processing unit 14. The TS (transport tsream) processing unit 15 performs TS processing, the encryption processing unit 16 performs encryption processing, and then the TS is supplied to the TS multiplexing unit 17.

  In addition, the content transmission device 11 includes an input terminal 18 to which content for storage-type broadcasting service is input. This storable broadcasting service is a service for transmitting content to be automatically stored in a receiving device, which will be described later, by broadcasting, and viewing the content automatically stored by the receiving device at a predetermined timing. As a result, a catch-up service called a push-type service can be realized.

  The content input to the input terminal 18 is subjected to MPEG compression processing in advance, and further subjected to PES processing / section processing. The pre-processed content is encrypted by the encryption processing unit 19, and the content processing unit 20 performs FLUTE processing, IP (internet protocol) packetization / header compression (ROHC) processing, and encapsulation (ULE). ) And the like, and the TS processing unit 21 performs the TS processing, and then supplies the TS to the TS multiplexing unit 17.

  The content transmission device 11 includes an EPG (electronic program guide) data generation unit 22. The EPG data generation unit 22 generates program attribute information such as SI (service information) and PSI (program specific information) for creating an electronic program guide that is a delivery schedule table for content for a real-time broadcasting service. Yes. The program attribute information generated by the EPG data generation unit 22 is subjected to TS conversion processing by the TS conversion processing unit 23 and then supplied to the TS multiplexing unit 17.

  The TS multiplexing unit 17 multiplexes the TSs output from the TS processing units 21 and 23 and the encryption processing unit 16. The TS multiplexed by the TS multiplexer 17 is subjected to encoding processing corresponding to the transmission path by the transmission path encoding section 24, and then supplied to the antenna 26 via the output terminal 25 and transmitted.

  Further, the content for storage-type broadcasting service that has been encrypted by the encryption processing unit 19 is supplied to the input terminal 29 of the network server 28 via the output terminal 27. The network server 28 supplies the content supplied to the input terminal 29 to an HDD (hard disk drive) 30 which is a recording device, and records it on the hard disk 30a. The HDD 30 is connected to a network 33 such as the Internet via a network interface 31 and an input / output terminal 32.

  When the HDD 30 receives a content acquisition request from the network 33 via the input / output terminal 32 and the network interface 31, the HDD 30 reads all or part of the requested content from the hard disk 30a. 32 to the network 33. Thereby, a catch-up service called a communication type service can be realized.

  Further, when the EPG data generation unit 22 creates program attribute information for creating an electronic program guide for the content for the real-time broadcast service, the push-type service and the communication type are included in the content for the real-time broadcast service. For content for which a catch-up service is provided by at least one of the services, flag information for displaying that fact on the electronic program guide is added.

  In addition to the message indicating that the catch-up service is provided, the flag information includes the acquisition destination of the content provided by the catch-up service (push-type service or communication-type service, and the distribution in the case of communication-type service) Information indicating the original network server 28), information indicating the expiration date of the catch-up service, whether the use of the catch-up service is charged or free, and information indicating the fee if charged is also included. ing.

  FIG. 2 shows an example of a content receiving device 34 that is a receiving side in the multimedia broadcasting service. That is, the digital broadcast signal received by the antenna 35 is supplied to the channel selection demodulation unit 37 via the input terminal 36. The channel selection demodulator 37 selects a broadcast signal of a desired channel from the input broadcast signal, and demodulates the TS by performing demodulation processing on the selected broadcast signal.

  The TS output from the channel selection / demodulation unit 37 is supplied to the TS separation unit 38, the TS corresponding to the content for real-time broadcasting service, the TS corresponding to the content for storage broadcasting service, and the EPG It is separated into TS corresponding to the program attribute information generated by the data generation unit 22.

  Among these, the TS corresponding to the content for the real-time broadcasting service is subjected to encryption decryption processing by the decryption processing unit 39, and is converted into PES / section by video and audio by the PES / section separation unit 40. After being divided into contents, the MPEG decoder 41 performs decompression processing on each of the video and audio contents, and then supplies them to the selective multiplexing unit 42.

  The TS corresponding to the program attribute information separated by the TS separation unit 38 is supplied to the program guide creation unit 43 to be used for creating content for OSD (on screen display) for displaying the electronic program guide. Is done. Then, the OSD content corresponding to the electronic program guide created by the program guide creation unit 43 is supplied to the selection multiplexing unit 42.

  Further, the TS corresponding to the content for the storage-type broadcast service separated by the TS separation unit 38 is encapsulated (ULE) decoding processing, IP packetization / header compression (ROHC) decoding processing by the content decoding unit 44, After the FLUTE decoding process or the like, the HDD 45 records (accumulates) the data on the hard disk 45a.

  The content read from the hard disk 45a by the HDD 45 is subjected to encryption decryption processing by the decryption processing unit 46 and decoded into video and audio content by the decoder 47, and then the selective multiplexing unit. 42.

  The selective multiplexing unit 42 selectively multiplexes the video content supplied from the MPEG decoder 41, the program guide creation unit 43, and the decoder 47, for example, for multi-screen display, and displays the video. The video is output to the unit 48 and displayed. The selective multiplexing unit 42 selectively outputs the audio content supplied from the MPEG decoder 41 and the decoder 47 to the speaker 49 for audio reproduction.

  Here, in the content receiving device 34, all operations including the above-described various receiving operations and recording / reproducing operations are comprehensively controlled by the control unit 50. The control unit 50 includes a central processing unit (CPU) 50a, receives operation information sent from the operation unit 51, and controls each unit so that the operation content is reflected.

  In this case, the control unit 50 uses the memory unit 50b. The memory unit 50b mainly includes a ROM (read only memory) storing a control program executed by the CPU 50a, a RAM (random access memory) for providing a work area to the CPU 50a, various setting information and control information. And so on.

  Further, the control unit 50 can generate an acquisition request for desired content to the HDD 30 of the network server 28 via the communication control unit 52. That is, the communication control unit 52 generates an acquisition request for a desired content from the HDD 30 via the network interface 53, the input / output terminal 54, the network 33, the input / output terminal 32 of the network server 28, and the network interface 31. .

  The communication control unit 52 acquires the content read by the HDD 30 from the hard disk 30a based on the content acquisition request via the network interface 31, the input / output terminal 32, the network 33, the input / output terminal 54, and the network interface 53. The data is recorded on the hard disk 45a by the HDD 45.

  This allows the user to view not only a real-time broadcast service for viewing various contents such as broadcast programs and data broadcasts in real time, but also a push-type for viewing various contents transmitted for storage and stored in the HDD 45 at an arbitrary timing. And a communication-type catch-up service for acquiring and viewing necessary content from the network server 28 at an arbitrary timing.

  FIG. 3 shows an example of an electronic program guide displayed on the video display section 48 based on the OSD content created by the program guide creation section 43 to display the electronic program guide. In this electronic program guide, the date and time for a predetermined time (7 hours in the figure) are arranged on the vertical axis, and a plurality of (three in the figure) channels are arranged on the horizontal axis. In the designated display column, the program scheduled to be broadcast at that time is displayed.

  That is, assuming that the current date and time is 17:20 on July 10, programs from 17:00 to 24:00 before that day are displayed. In this case, “Parliamentary broadcast” will be broadcast on the general channel from 17:00 on July 10, “Sumo” on the sports channel, and “** Live” on the music channel will start broadcasting from 18:00 on the same day. “Drama” will be broadcast on the channel, and “Professional Baseball” will be broadcast on the sports channel. “Soccer” will be broadcast on the general channel from 20:00 on the same day. “Basket” is scheduled to start broadcasting, and “Overseas Sports” on the general channel and “Hit Chart” on the music channel are scheduled to start broadcasting from 22:00 on the same day.

  Here, as described above, when the EPG data generation unit 22 generates program attribute information for generating an electronic program guide, the electronic program guide indicates that the content is provided with a catch-up service. Flag information for display on the screen is added. When the program guide creation unit 43 creates the OSD content for displaying the electronic program guide, the content to which flag information is added is set in advance after the broadcast of the content is started. When a predetermined time (for example, 30 minutes) has elapsed, a message indicating that a catch-up service is provided for the content is displayed on the electronic program guide.

  Specifically, a catch-up service is prepared for “drama” scheduled to start broadcasting from 18:00 on the general channel and “** live” starting broadcasting from 17:00 on the music channel. Suppose that Then, in the state where the current time has reached 18:30, as shown in FIG. 4, the catch-up service is respectively displayed in the display column of “drama” of the general channel and the display column of “** live” of the music channel. A “catch-up” message is displayed indicating that it will be provided.

  As for the display column of “** Live” of the music channel, since the current time is assumed to be 17:20 in FIG. 3, it is 30 after “** Live” is broadcast (17:00). Since the minutes have not passed, the message “catch up” has not yet been displayed.

  In the state where the current time has reached 18:30, in the actual electronic program guide, the program before 18:00 is not displayed, and the program display for 1 hour from 18:00 is performed. In FIG. 4, the programs before 18:00 are surrounded by hatching in order to make the explanation easier to understand compared with FIG. 3.

  FIG. 5 shows a flowchart summarizing the processing operation in which the program guide creation unit 43 displays a message to the effect that a catch-up service is provided in the electronic program guide. That is, when the process is started (step S5a), the program guide creation unit 43, when creating the OSD content for displaying the electronic program guide in step S5b, provides a catch-up service for the content of each program. It is determined whether or not flag information indicating that the information is to be provided is added, and the processing is ended (step S5e) for the content that is determined not to be added (NO).

  In addition, for the content for which it is determined that the flag information is added (YES) in step S5b, the program guide creation unit 43, in step S5c, sets a predetermined time (this is set in advance) after the content starts broadcasting. In this case, it is determined whether or not 30 minutes have elapsed. If it is determined that 30 minutes have not elapsed (NO), the process is terminated (step S5e).

  On the other hand, if it is determined in step S5c that the predetermined time has elapsed (YES), the program guide creation unit 43 indicates that a catch-up service is provided in the display column of the electronic program guide for the content in step S5d. The message “catch up” shown is displayed, and the process is terminated (step S5e).

  Note that the processing described with reference to FIG. 5 may be executed when the user operates the operation unit 51 to request display of the program guide, or may be executed periodically (for example, every minute). It may be executed when a change in the program attribute information is detected.

  Here, the control unit 50 of the content receiving device 34 selects and selects a desired program currently being broadcast from the electronic program guide displayed on the video display unit 48 by the user operating the operation unit 51. When viewing of a program is requested, the content of the program is received and operated for viewing.

  FIG. 6 shows a flow chart summarizing the processing operation in which the control unit 50 receives a program selected by the user from the electronic program guide and requested to be viewed for viewing. That is, when the process is started (step S6a), the control unit 50 determines in step S6b whether or not a program is selected from the electronic program guide and requested to be viewed, and when it is determined that no viewing is requested. (NO), the process ends (step S6h).

  If it is determined in step S6b that the program is requested to be viewed (YES), the control unit 50 determines whether or not a catch-up service is provided for the program in step S6c, and is not provided. If it is determined (NO), in step S6d, the program requested to be viewed is received in real time from the current time for viewing, and the process ends (step S6h).

  On the other hand, when it is determined in step S6c that the catch-up service is provided for the program requested to be viewed (YES), the control unit 50 is based on the flag information added to the received program attribute information in step S6e. Then, the OSD content for displaying the service use screen for prompting the user to use the catch-up service is created and displayed on the video display unit 48.

  As shown in an example in FIG. 7, the service usage screen indicates that a catch-up service is provided for a program requested by the user. For example, “This program has already started broadcasting, A message such as “The service is available and can be viewed from the beginning of the program if desired” is displayed.

  In addition, this service usage screen shows the expiration date of the catch-up service, for example, information such as “Available until XX year, month, day, and day”, and whether the use of the catch-up service is charged or free If there is a fee, information indicating the fee is also displayed.

  Further, on this service usage screen, an item “desired” and an item “not desired” for the catch-up service are displayed, and the user operates the operation unit 51 to select and determine one of the items. can do. The service use screen also displays a “return” item. When the user operates the operation unit 51 to select and determine the “return” item, the user can return to the previous display screen.

  Returning to FIG. 6 again, in step S6f, the control unit 50 determines whether or not the user has requested the use of the catch-up service, that is, the item “desired” is selected on the service use screen shown in FIG. If it is determined that it has not been requested (NO), the process proceeds to step S6d.

  If it is determined in step S6f that the user has requested use of the catch-up service (YES), the control unit 50 is included in the flag information added to the received program attribute information in step S6g. Then, based on the information indicating the acquisition destination of the content provided by the catch-up service, the content of the program requested to be viewed is searched for and acquired, and the process is terminated by allowing the program to be viewed by the user from the beginning of the program (step S6h). )

  In the process of step S6g, if the content provided by the catch-up service is content for a storage-type broadcast service stored in the HDD 45, it becomes a push-type catch-up service and is stored in the HDD 30 of the network server 28. For content, it is a communication-type catch-up service.

  Here, the information indicating the acquisition destination of the content provided by the catch-up service is, for example, the URL (uniform resource locator) of the network server 28 that provides the catch-up service, or ARIB (association of the storage control method). This is descriptive language type metadata defined by “ARIB STD-B38” standardized by radio industries and businesses.

  According to the above-described embodiment, when the content transmission device 11 creates program attribute information for creating an electronic program guide, flag information indicating that is added to the content provided with the catch-up service. To send. When the electronic program guide is displayed on the content receiving device 34, a message indicating that is displayed in the program display column for the content for which the catch-up service is provided.

  For this reason, when the user looks at the electronic program guide, the user can easily recognize which program is provided with the catch-up service, and thus the user can easily use the catch-up service. As a result, it is easy to use for the user and the convenience can be further improved.

  In the above-described embodiment, the catch-up service is provided for a content for which the catch-up service is provided after a predetermined time (in this case, 30 minutes) has elapsed since the broadcast of the content is started. A message indicating that is displayed on the electronic program guide.

  However, the timing for displaying the message indicating that the catch-up service is provided on the electronic program guide is not limited to this. For example, the broadcast station provides the catch-up service from the start of broadcasting for each program. It is possible to appropriately set the time until the message indicating that the message is displayed. This can be easily realized by including in the flag information added to the program attribute information information specifying the time from when the program starts broadcasting until a message indicating that the catch-up service is provided is displayed. Can be made.

  Specifically, as shown in FIG. 8, a catch-up service is displayed in the “Pro Baseball” display field of the sports channel that has been broadcast from 18:00 with the current time reaching 20:30. A “catch up” message is displayed indicating that is provided. That is, a message indicating that the catch-up service is provided after two hours or more have elapsed from the start of broadcasting is displayed.

  In the state where the current time has reached 20:30, in the actual electronic program guide, the program before 20:00 is not displayed, and the program is displayed for 7 hours from 20:00. In FIG. 8, the program before 20:00 is shown in hatched for easier understanding of the explanation than FIG. 4.

  Further, when the communication type catch-up service is performed, for example, when the network server 28 cannot be dealt with due to a large number of content acquisition requests, the communication type catch-up service is currently stopped. It is also possible to transmit a message indicating this to the user by broadcasting.

  That is, on the transmission side, information indicating whether the communication type catch-up service is currently being provided or stopped is included in the flag information added to the program attribute information and broadcast together with the program attribute information. Can do. In this way, the user can be informed whether the communication type catch-up service is being provided or stopped without using a network line.

  FIG. 9 shows whether a communication-type catch-up service is currently provided from the broadcasting station side when the control unit 50 receives a program selected by the user from the electronic program guide and requested to view the program. The flowchart which put together the process operation | movement when the information which shows whether it has stopped is transmitted is shown.

  That is, when the process is started (step S9a), the control unit 50 determines whether or not a program is selected from the electronic program guide and requested for viewing in step S9b. When it is determined that the program is not requested for viewing (NO), the control unit 50 ends the process (step S9j).

  If it is determined in step S9b that the program is requested to be viewed (YES), the control unit 50 determines whether or not a catch-up service is provided for the program in step S9c, and is not provided. If it is determined (NO), in step S9d, the program requested to be viewed is received in real time from the current time and is used for viewing, and the process ends (step S9j).

  On the other hand, if it is determined in step S9c that the catch-up service is provided for the program requested to be viewed (YES), the control unit 50 includes the flag information added to the received program attribute information in step S9e. Based on the information indicating whether the communication type catch-up service is currently being provided or stopped, it is determined whether or not the communication type catch-up service is currently being provided.

  If it is determined that the communication-type catch-up service is currently being provided (YES), the control unit 50 determines whether or not the user has requested use of the catch-up service in step S9f, and requests the request. If it is determined that it has not been performed (NO), the process proceeds to step S9d.

  If it is determined in step S9f that the user has requested use of the catch-up service (YES), the control unit 50 is included in the flag information added to the received program attribute information in step S9g. Then, based on the information indicating the acquisition destination of the content provided by the catch-up service, the content of the program requested to be viewed is searched for and acquired, and the process is terminated by providing it to the user viewing from the beginning of the program (step S9j). )

  On the other hand, when it is determined in step S9e that the communication type catch-up service is currently stopped (NO), the control unit 50 determines in step S9h that the communication type catch-up service is currently stopped. A message to be displayed is displayed on the video display unit 48.

  Thereafter, in step S9i, the control unit 50 displays information indicating whether the communication-type catch-up service is currently being provided or stopped, which is included in the flag information added to the received program attribute information. Based on this, the provision of the communication-type catch-up service is started, that is, the display of the message indicating that the communication-type catch-up service is currently stopped is terminated, and the process of step S9d is performed. To be migrated.

  Even if the communication-type catch-up service is stopped, if the push-type catch-up service can be provided, the push-type catch-up is not stopped. It is also possible to deal with by providing only services.

  Further, when the user starts watching the program using the catch-up service, if the playback position of the program content catches up with a position corresponding to the current time by performing fast-forward playback, the catch-up service starts real-time playback. Can be automatically switched to a broadcast service. In this way, when a communication type catch-up service is used, it is not necessary to use a network line or a network server after switching to the real-time type broadcast service, and the burden can be reduced.
