Description

  The present invention relates to a digital broadcast receiving apparatus that records and reproduces broadcast content and reproduces broadcast content on a network.

  Conventional digital broadcast receivers receive broadcast waves such as terrestrial broadcasts, cable television broadcasts, and satellite broadcasts to display broadcast contents. Also, in a conventional broadcasting system, broadcast content related information such as broadcast content name and start time of broadcast content is superimposed on broadcast content data distributed by radio waves from broadcast stations, cable transmission signals from cable broadcast stations, etc. And distributed to each home as electronic data. As a result, in each home, it is possible to confirm broadcast content information as an electronic program guide (EPG).

  On the other hand, with the recent development of broadband environments, there are services that allow viewing of broadcast contents having the same contents as broadcast contents distributed via broadcast waves via a network such as the Internet. Many of these services employ a VOD (Video On Demand) method (hereinafter referred to as VOD). With this VOD, the user can view the broadcast content whenever he / she wants to view it, and can view the desired broadcast content even if he / she misses the broadcast content or forgets to record. However, when the user views the broadcast content, there is a problem that it is necessary to check whether the content is to be distributed later by VOD. In order to solve this problem, there is a technique for displaying the presence or absence of VOD on an EPG (for example, Patent Document 1).

JP 2008-263434 A

  However, when recording broadcast content, even if the presence or absence of VOD is displayed for each broadcast content in the EPG as in Patent Document 1, the user can determine whether or not there is broadcast content redistributed by VOD for each broadcast content. It was necessary to check and determine whether recording was necessary. For example, the user does not need to record broadcast content that is redistributed by VOD, but it is necessary to record broadcast content that is not redistributed by VOD. In general, a broadcast content redistributed by VOD has a viewable time limit (broadcast content distribution period), and the user needs to consider the broadcast content distribution period. For example, when the broadcast content distribution period is short, the user is unlikely to be able to view the broadcast content within the broadcast content distribution period, so the broadcast content needs to be recorded and held for a long time. In addition, when the broadcast content distribution period is sufficiently long, the user is highly likely to be able to view the broadcast content redistributed by VOD, so there is no need to record. In this way, the user compares the broadcast content distribution period with the period during which he / she wants to view the broadcast content, that is, the period when the broadcast content is recorded and stored (broadcast content recording period), and determines whether or not recording is necessary for each broadcast content. There was a need to do.

  Therefore, an object of the present invention is to obtain a digital broadcast receiving apparatus that determines whether or not broadcast content needs to be recorded without considering the broadcast content distribution period.

The digital broadcast receiving apparatus of the present invention includes a first broadcast content distributed by digital broadcast, a second broadcast content distributed via a communication network in a content corresponding to the first broadcast content, and the second broadcast content A broadcast content information receiving unit for receiving a broadcast content distribution period, and among the first broadcast content received by the broadcast content information receiving unit, the recorded content to be recorded and the recorded content are recorded. A recording reservation information receiving unit for receiving a broadcast content recording period indicating a recording period as a recording reservation, and recording of the broadcast content received as the recording reservation based on the broadcast content distribution period and the broadcast content recording period. A broadcast content recording management unit for determining necessity, and the broadcast content recording manager A storage unit that stores the recorded content when it is determined that recording is necessary, and does not store the recorded content when it is determined that recording is not required by the broadcast content recording management unit. And

  The digital broadcast receiver according to the present invention determines whether or not recording of the first broadcast content reserved for recording out of the first broadcast content broadcast on the broadcast wave is based on the broadcast content recording period and the broadcast content distribution period. Since the determination is made, the user can view the broadcast content without considering the broadcast content distribution period.

  First, as a premise of the description of the digital broadcast receiving apparatus according to the first embodiment, a digital broadcast broadcasting system according to the first embodiment will be described with reference to FIG.

  The digital broadcast broadcasting system according to Embodiment 1 includes a digital broadcast distribution device 1, a digital broadcast reception device 2, and a VOD distribution server 3.

  The digital broadcast distribution apparatus 1 is operated by a broadcasting station or the like, and multiplexes broadcast content data such as video and audio itself, data of the broadcast content (first broadcast content) and EIT (Event Information Table) information to broadcast. It is distributed to the digital broadcast receiver 2 as a wave. Here, the EIT information is information related to a program, and has, for example, a broadcast content name and a broadcast content start time as data. The EIT information is distributed as SI (Service Information) information together with other information SDT (Service Description Table) information (information on channels) and the like. The digital broadcast distribution apparatus 1 is connected to a communication network 5 such as the Internet via a GW 4a that is a router or the like. Therefore, the digital broadcast distribution apparatus 1 can distribute broadcast content and SI information to the VOD distribution server 3 via the communication network 5. In addition, although the digital broadcast distribution apparatus 1 distributes broadcast content data as a broadcast wave to the digital broadcast reception apparatus 2, the broadcast content data may be distributed by a cable transmission signal or the like. In the following description, distribution of broadcast content using broadcast waves will be described as an example.

  The digital broadcast receiver 2 is a device that receives broadcast waves distributed from the digital broadcast distribution device 1. Similarly to the digital broadcast distribution device 1, the digital broadcast reception device 2 is connected to the communication network 5 via the GW 4b. Therefore, broadcast content (second broadcast content) redistributed by VOD from the VOD distribution server 3 via the communication network 5 can be received.

  The VOD distribution server 3 is a server device that distributes broadcast content redistributed by VOD. The VOD distribution server 3 distributes broadcast content received from the digital broadcast distribution device 1 from the VOD distribution server 3 to the digital broadcast reception device 2 via the communication network 5 and the GW 4c as broadcast content redistributed by VOD. Therefore, the user can view the broadcast content corresponding to the broadcast content distributed from the digital broadcast distribution apparatus 1 using the VOD distribution server 3. Note that the corresponding content here refers to broadcast content having the same content. However, the same contents may not be completely the same, and may be edited if the broadcast content is rebroadcast.

  Next, the configuration of the digital broadcast distribution apparatus 1 will be described with reference to FIG.

  The digital broadcast distribution apparatus 1 includes a video encoding unit 11, an audio encoding unit 12, an SI information generation unit 13, a sectioning unit 14, a Mux processing unit 15, a data distribution unit 16, and a data communication unit 17.

  The video encoding unit 11 encodes a video signal of broadcast content.

  The audio encoding unit 12 encodes the audio signal of the broadcast content.

  The SI information generation unit 13 generates SI information having EIT information based on the broadcast content related information. Broadcast content related information is information related to broadcast content scheduled to be distributed now and in the future, and includes a broadcast content name, a broadcast start time, and the like. In general, the digital broadcast receiving apparatus 2 creates an EPG based on this SI information.

  The sectioning unit 14 performs sectioning to store the SI information generated by the SI information generating unit 13 in a section format SI table.

  The Mux processing unit 15 multiplexes the SI information sectioned into the video signal encoded by the video encoding unit 11 and the audio signal encoded by the audio encoding unit 12 to generate a transport stream. Here, the transport stream is one of multiple signal formats and is a signal format adopted as a multiplexed signal for digital broadcasting. The transport stream can transmit a video signal, an audio signal, and SI information as one stream regardless of the type of transmission path.

  The data distribution unit 16 modulates the transport stream generated by the Mux processing unit 15 and distributes it to the digital broadcast receiving apparatus 2 as a broadcast wave.

  The data communication unit 17 is connected to the communication network 5 via the GW 4a and further distributes the broadcast content to the VOD distribution server 3 via the GW 4c.

  Here, EIT information included in the SI information distributed by the digital broadcast distribution apparatus 1 will be described in detail with reference to FIGS. 3 and 4. FIG. 3 is a diagram illustrating a data structure of EIT information according to the first embodiment. FIG. 4 is an example of VOD redistribution schedule information according to the first embodiment.

  As shown in FIG. 3, the EIT information includes various information related to broadcast content in “Event_information_section ()”, for example, the start time “start_time” of the broadcast content, and the length “duration” of the broadcast content. Etc. Information regarding these broadcast contents is described in association with an identifier “event_id” for identifying the broadcast contents. Further, in the subsequent descriptor area “descriptor ()”, a separately defined descriptor is appropriately inserted, and various broadcast content related information can be additionally described. The digital broadcast distribution apparatus 1 describes the VOD redistribution schedule information in this descriptor area “descriptor ()”. Note that the VOD redistribution schedule information is information related to broadcast content that is redistributed by VOD, and includes a broadcast content distribution period, a contract ID (contract information), and a URI, as shown in FIG. Here, the contract ID is an ID managed by the VOD distribution server 3. Generally, when the user of the digital broadcast receiving apparatus 2 has previously contracted with the administrator of the VOD distribution server 3, a code corresponding to the contract ID is stored in the digital broadcast receiving apparatus 2. Using this code and the contract ID as a key, the user can view the broadcast content redistributed by VOD. Furthermore, the URI is information indicating the location of the broadcast content redistributed by the VOD existing on the Internet, and the URI widely used in the home Internet is a kind of URL.

  Next, the configuration of digital broadcast receiving apparatus 2 according to Embodiment 1 will be described with reference to FIG. FIG. 5 is a diagram showing the configuration of the digital broadcast receiving apparatus according to the first embodiment.

  The antenna 201 receives a broadcast wave distributed from a broadcast station.

  The tuner 202 performs tuning processing of the broadcast wave received by the antenna 201 and conversion into an IF (Intermediate Frequency) signal. The IF signal refers to an intermediate frequency set between the frequency of the broadcast wave and the frequency of the original video signal or the like.

  The demodulator 203 demodulates the modulated broadcast wave and outputs a transport stream in which video signals, audio signals, and SI information are multiplexed.

  The Demux processing unit 204 separates the video signal, audio signal, and SI information from the transport stream demodulated by the demodulation unit 203. The separated SI information is output to the storage unit 215 described later.

  The decoding processing unit 205 performs processing for decoding the separated video signal and audio signal.

  The video control unit 206 mixes the video signal acquired from the decoding processing unit 205 and the image image acquired from the display screen control unit 207 described later, and outputs the mixed image to the video D / A converter 208.

  The display screen control unit 207 creates an image and outputs it to the video control unit 206. For example, when displaying an EPG screen while reproducing a broadcast wave, the display screen control unit 207 starts the broadcast content name and broadcast content on the display screen control unit 207 based on SI information separated from the transport stream. An image of an EPG screen on which time and the like are displayed is created and output to the video control unit 206. That is, the display screen control unit 207 creates an image of a screen operated by the user, such as a screen for recording reservation by the user (recording content list) and a screen for confirming recording reservation (reservation content list). .

  The video D / A converter 208 performs digital / analog conversion on the video signal or image input from the video control unit 206 and outputs it to the monitor 209.

  The monitor 209 displays the video signal converted into the analog video signal as a video.

  The audio D / A converter 210 performs digital / analog conversion on the audio signal decoded by the decoding processing unit 205.

  The speaker 211 reproduces the sound signal converted into the analog sound signal as sound.

  The communication unit 213 is an interface that performs data communication with the communication network 5 illustrated in FIG. 1. For example, the communication unit 213 receives broadcast content redistributed from the VOD distribution server 3 by VOD.

  The operation receiving unit 214 receives an operation input signal from the user via the remote controller 214a. For example, the operation receiving unit 214 receives signals such as recording reservation, channel change, and broadcast content recording period as operation input signals.

  The storage unit 215 is a storage medium such as an HDD, and stores the SI information separated from the transport stream by the Demux processing unit 204. Further, when the broadcast content of the broadcast wave received by the antenna 201 is reserved for recording, the storage unit 215 stores the video signal and audio signal of the broadcast content reserved for recording as video data and audio data.

  The storage capacity monitoring unit 215a monitors the storage capacity indicating how much broadcast content the storage unit 215 can record.

  The VOD processing unit 216 performs reproduction processing of broadcast content redistributed by the VOD received by the communication unit 213. The reproduction process here refers to a decoding process of broadcast content distributed in a streaming format.

  The broadcast content recording period setting unit 217 sets and manages the broadcast content recording period. The broadcast content recording period setting unit 217 receives the operation content and records the broadcast content recording period in the storage unit 215 when the broadcast content recording period is input to the operation receiving unit 214 by a user's remote control operation.

  The VOD redistribution schedule determination unit 218 determines whether there is broadcast content that is redistributed by VOD. Specifically, when a recording reservation operation is performed by the user, the VOD redistribution schedule determination unit 218 refers to the descriptor area “descriptor ()” of the EIT information included in the SI information read from the storage unit 215. To do. Whether or not the broadcast content is redistributed by VOD is determined based on whether or not the VOD redistribution schedule information descriptor is described in this descriptor area “descriptor ()”. If there is a VOD redistribution schedule information identifier, it is determined that the broadcast content is redistributed by VOD.

  The broadcast content recording management unit 219 creates a reserved content management table and a recorded content management table. Here, the reserved content management table is a management table for creating a reserved content list displayed on the monitor 209 when the user confirms a recording reservation. The recorded content management table is a management table for creating a recorded content list displayed on the monitor 209 when the broadcast content reserved for recording by the user is reproduced. Further, the broadcast content recording management unit 219 determines the recording type described in the reserved content management table and the recorded content management table.

  Here, the reserved content management table, reserved content list, recorded content management table, and recorded content list will be described with reference to FIGS. FIG. 6 is a reserved content management table created by the broadcast content recording management unit according to the first embodiment. FIG. 7 shows a reserved content list created by the broadcast content recording management unit according to the first embodiment. FIG. 8 is a recorded content management table created by the broadcast content recording management unit according to the first embodiment. FIG. 9 shows a recorded content list created by the broadcast content recording management unit according to the first embodiment.

  As shown in FIG. 6, the reserved content management table includes Event_ID, date, broadcast content name, recording type, broadcast content distribution period, access destination, and contract ID. For example, when a user makes a recording reservation for a movie “XXX” broadcast on December 3, 2012, the broadcast content recording management unit 219 converts the Event_ID, date, and broadcast content name from the EIT information to the EIT information. The broadcast content distribution period, access destination, and contract ID are acquired from the included VOD redistribution schedule information, and these information are described in the reserved content management table. The date refers to the broadcast date when the broadcast content is distributed from the digital broadcast distribution apparatus 1. The access destination describes the URI when the recording type is “VOD”, and the location where the broadcast content file is stored when the recording type is “recording”. At this time, the access destination is blank in the history building “ΔΔ” in the reserved content management table. This is blank when creating the reserved content management table because the position of the recorded broadcast content file is written after recording. Further, the items of the reserved content management table do not necessarily have to be Event_ID, date, broadcast content name, recording type, broadcast content distribution period, access destination, contract ID, for example, acquired from SI information such as start time of broadcast content Any information can be used.

  As shown in FIG. 7, the reserved content list includes a date on which broadcast content is broadcast and a broadcast content name. In this example, the user can confirm that the movie “XX”, the news at 7 o'clock, and the history hall “ΔΔ” are each reserved for recording. Note that the items in the reserved content list are not necessarily composed of the date and the broadcast content name, but may be items that constitute the reserved content management table.

  As shown in FIG. 8, the recorded content management table includes Event_ID, date, broadcast content name, recording type, broadcast content distribution period, access destination, and contract ID. In the reserved content management table described with reference to FIG. 6, the location of the file described in the storage unit 215 is described as the access destination of the historical hall “ΔΔ” whose recording type is “recording”. In other items, the recorded content management table has the same configuration as the reserved content management table, and thus the description thereof is omitted.

  As shown in FIG. 9, the recorded content list includes a broadcast content name, a date, and a recording type. When the broadcast content recording management unit 219 selects a broadcast content on the recorded content list that the user desires to view, the communication unit 213 accesses the access destination of the selected broadcast content by referring to the recorded content management table. Connect automatically to the destination. Note that the recorded content list does not necessarily include only the broadcast content name, date, and recording type, but may be items that constitute the recorded content management table.

  Here, the recording type determination of the broadcast content recording management unit 219 will be described.

  The broadcast content recording management unit 219 determines the recording type based on the broadcast content distribution period of the broadcast content and the broadcast content recording period set by the user when the user makes a recording reservation for the broadcast content that the user wants to view. Specifically, the broadcast content recording management unit 219 determines to record when there is a broadcast content recording period that is not included in the broadcast content distribution period, and determines VOD otherwise. For example, taking the movie “XXX” in FIG. 6 as an example, if the broadcast content recording period set by the user is “2012/12 / 4-2012 / 12/25”, the broadcast content recording period is broadcast content. It is all included in the distribution period “2012/12/4-2013/2/10”. Therefore, the broadcast content recording management unit 219 determines that the recording type is VOD.

  On the other hand, in the case of the history hall “ΔΔ” in FIG. 6, when the broadcast content recording period set by the user is “2012/12 / 19-2012 / 12/27”, the broadcast content recording period is broadcast content. There is a period “2012/12 / 25-2012 / 12/27” that is not included in the distribution period “2012/12 / 19-2012 / 12/24”.

  As described above, when there is a broadcast content recording period that is not included in the broadcast content distribution period, if the broadcast content recording management unit 219 determines that the recording type is VOD, the user can select “2012/12 / 25-2012”. / 12/27 "cannot watch the broadcast content history museum" △△ "that he / she wants to watch. Therefore, the broadcast content recording management unit 219 determines that the recording type is recording.

  Note that there may be a case where broadcast content redistributed by VOD is distributed in a plurality of broadcast content distribution periods. Also in this case, the broadcast content recording management unit 219 determines that the recording is a recording when there is a broadcasting content recording period that is not included in the broadcasting content distribution period, and determines that it is VOD otherwise. For example, the broadcast content distribution period is “2012/12 / 4-2013 / 2/10, 2013/2 / 15-2013 / 3/25”, and the broadcast content recording period is “2012/12 / 4-2013-3 / 25”. ”, Since there is a period“ 2013/2 / 11-2013 / 2/14 ”that is not included in the broadcast content recording period in the broadcast content distribution period, the broadcast content recording management unit 219 determines that the recording type is recording. To do.

  The broadcast content determined to be recorded by the broadcast content recording management unit 219 is stored in the storage unit 215. The broadcast content stored in the storage unit 215 is decoded by the decoding processing unit 205 and reproduced by the video control unit 206, the video D / A converter 208, the monitor 209, the audio D / A converter 210, and the speaker 211.

  The broadcast content determined as VOD by the broadcast content recording management unit 219 is received from the VOD distribution server 3 by the communication unit 213. Broadcast content redistributed by VOD is streamed by the VOD processing unit 217 and reproduced by the video control unit 206, the video D / A converter 208, the monitor 209, the audio D / A converter 210, and the speaker 211.

  The decoding processing unit 205, video control unit 206, video D / A converter 208, monitor 209, audio D / A converter 210, speaker 211, and VOD processing unit 216 are collectively referred to as a broadcast content playback unit.

  The control unit 212 controls the operation of each component via the internal bus 200.

  Next, the operation of the digital broadcast receiving apparatus 2 according to the first embodiment will be described with reference to FIGS. FIG. 10 is an operation flowchart of the digital broadcast receiving apparatus according to the first embodiment. FIG. 11 shows an example of a broadcast content recording period setting screen according to the first embodiment. FIG. 12 shows an example of broadcast content recording period information according to the first embodiment. FIG. 13 is an operation flowchart for determining necessity of recording by the broadcast content recording management unit according to the first embodiment. FIG. 14 is a diagram for explaining a procedure by which the broadcast content recording management unit according to Embodiment 1 creates a reserved content management table. FIG. 15 is a diagram illustrating a procedure in which the broadcast content recording management unit according to Embodiment 1 creates a recorded content management table. FIG. 16 is an operation flowchart at the time of reproduction of the digital broadcast receiving apparatus according to the first embodiment. FIG. 17 shows an example of a recorded content list according to the first embodiment. In the following description, an example in which “Drama“ XYZ ”” broadcast on December 25, 2013 by the user is reserved for recording will be used. That is, the operation of adding “drama“ XYZ ”” to the recorded content management table in FIG. 8 will be described.

  In S <b> 1, the antenna 201 receives from the digital broadcast distribution device 1 a broadcast wave composed of multiplexed broadcast content data and SI information. At this time, the SI information includes EIT information related to the drama “XYZ” and VOD redistribution schedule information included in the EIT information. The EIT information includes Event_ID “114”, broadcast content name “drama“ XYZ ””, and date “2013/12/25”. Furthermore, the VOD redistribution schedule information includes a broadcast content distribution period “2013/12 / 26-2014 / 2/26”, an access destination URI “http: //www.***”, and a contract ID “1345”. Shall be included.

  Further, the demodulator 203 demodulates the received broadcast wave and outputs it to the Demux processor 204 as a transport stream.

  Further, the Demux processing unit 204 separates the transport stream into broadcast content and SI information. The separated SI information is stored in the storage unit 215.

  In S2, the user selects the broadcast content “drama“ XYZ ”” to be viewed and recorded by operating the remote control 214a from the EPG screen or the like. In the following description, the broadcast content that the user desires to view and records is described as “recorded content”.

  The broadcast content recording period setting unit 217 displays a broadcast content recording period setting screen on the monitor 209 in response to selection of the recorded content “drama“ XYZ ””. The broadcast content recording period setting screen is a screen for the user to set a broadcast content recording period. For example, FIG. 11 shows a broadcast content recording period setting screen displayed at the time of recording reservation, in which the broadcast content recording period “30 days” is registered. The broadcast content recording period can be changed depending on the type of broadcast content. For example, the user can freely set the broadcast content recording period on the broadcast content recording period setting screen, such as 60 days when the broadcast content is a drama and 40 days when the broadcast content is a movie. The broadcast content recording period setting screen shown in FIG. 11 includes a storage unit 215 for 60 days from the broadcast date of the broadcast content for dramas, 40 days from the broadcast date of the broadcast content for movies, and 30 days from the broadcast date for broadcast content other than dramas and movies. This means that the recorded content is stored in In the following description, it is assumed that the value of the broadcast content recording period is calculated from the next day of the broadcast date.

  Also, the broadcast content recording period setting unit 217 creates broadcast content recording period information shown in FIG. 12 when the broadcast content recording period is set by a remote control operation from the user. The broadcast content recording period information is information in which the broadcast content recording period set by the broadcast content recording period setting unit 217 is associated with the type of broadcast content. Broadcast content recording period setting section 217 outputs broadcast content recording period information to storage section 215.

  Further, the storage unit 215 receives and stores the broadcast content recording period information.

  In S3, the broadcast content recording management unit 219 determines whether or not recording is required for the recording content reserved for recording. Here, with reference to FIG. 13, the operation of determining whether or not recording is necessary by the broadcast content recording management unit 219 in S3 will be described in detail. FIG. 13 is an operation flowchart for determining necessity of recording according to the first embodiment.

  In S31, the broadcast content recording management unit 219 confirms whether or not the scheduled recording content “drama“ XYZ ”” is scheduled to be distributed to the VOD redistribution schedule determination unit 218 with “Event_ID” of “drama“ XYZ ””. Is output.

  The VOD redistribution schedule determination unit 218 refers to the SI information in the storage unit 215 based on “Event_ID” of “drama“ XYZ ””. In addition, the VOD redistribution schedule determination unit 218 refers to the descriptor area “descriptor ()” of the EIT information included in the SI information. When there is a VOD redistribution schedule information descriptor in the descriptor area “descriptor ()”, the VOD redistribution schedule determination unit 218 determines that “drama“ XYZ ”” is redistributed in VOD. Further, the VOD redistribution schedule determination unit 218 acquires VOD redistribution schedule information and outputs it to the broadcast content recording management unit 219.

  The broadcast content recording management unit 219 acquires the VOD redistribution schedule information of “drama“ XYZ ”” from the VOD redistribution schedule determination unit 218, and stores information on “Drama“ XYZ ”” (Event_ID, date, (Broadcast content name, broadcast content distribution period, access destination, contract ID) are registered. In this example, as illustrated in FIG. 14, the broadcast content recording management unit 219 performs Event_ID “114”, date “2013/12/25”, broadcast content name “drama“ XYZ ””, broadcast content distribution period “2013”. / 12 / 26-2014 / 2/26 ", URI" http: //www.*** ", and contract ID" 1345 "are registered in the reserved content management table, and the process proceeds to S32. If there is no VOD redistribution schedule information, the broadcast content recording management unit 219 determines that “drama“ XYZ ”” is not redistributed by VOD, and proceeds to S4.

  In S <b> 32, the broadcast content recording management unit 219 refers to the contract ID from the VOD redistribution schedule information acquired from the VOD redistribution schedule determination unit 218, and “Drama“ XYZ ”” has been contracted in the digital broadcast receiving apparatus 2. It is determined whether or not. In this example, it is assumed that the contract has been made (including free of charge), and the process proceeds to S33. If the contract has not been completed, the process proceeds to S4.

  In S33, the broadcast content recording management unit 219 determines whether the broadcast content distribution period is included in the broadcast content recording period. The broadcast content recording management unit 219 acquires the broadcast content recording period from the storage unit 215 and compares it with the broadcast content distribution period registered in the reserved content management table. In this example, since the broadcast content distribution period is “2013/12 / 26-2014 / 2/26” and the broadcast content recording period is “60 days” from the day after the broadcast date “2013/12/25”, “2013/12” / 26−2013 / 2/23 ”, and the broadcast content recording period is included in the broadcast content distribution period, the broadcast content recording management unit 219 replaces the recorded“ drama “XYZ” ”. It is determined that “drama“ XYZ ”” redistributed by VOD is suitable, “VOD” is registered in the recording type of the reserved content management table of FIG. 14, and the process proceeds to S5.

  If the broadcast content recording period is not included in the broadcast content distribution period, the broadcast content recording management unit 219 determines that “drama“ XYZ ”” redistributed by VOD is not suitable as an alternative to recording. It is determined that there is, and “recording” is registered in the recording type of the reserved content management table, and the process proceeds to S4.

  If the process proceeds to S4, the broadcast content recording management unit 219 notifies the control unit 212 of the recording type “recording” registered in the reserved recording list at the broadcast start time of “drama“ XYZ ”” reserved for recording. Further, the control unit 212 accesses the Demux processing unit 204 and causes the storage unit 215 to store the video signal and the audio signal of the broadcast content “drama“ XYZ ”” separated in S1.

  In S <b> 5, the digital broadcast receiving apparatus 2 receives an operation from the user and executes playback of the recorded content determined to be recorded or VOD. Hereinafter, the reproducing operation will be described with reference to FIG. FIG. 16 is an operation flowchart at the time of reproduction of the digital broadcast receiving apparatus 2 according to the first embodiment.

  In S51, the user selects the recorded content reserved for recording from the recorded content list. For example, when the user selects “drama“ XYZ ”” in the recorded content list of FIG. 17, the broadcast content recording management unit 219 manages the recorded content corresponding to “drama“ XYZ ”” selected by the user. It detects from a table (FIG. 15).

  In S52, the broadcast content recording management unit 219 determines “VOD” or “recording” with reference to the recording type of “drama“ XYZ ”” detected from the recorded content management table. In this example, since the recording type of the detected recording content is “VOD”, the process proceeds to S53. If the recording type of the detected recording content is “recording”, the process proceeds to S54.

  In S53, since the recording type of the detected recorded content “drama“ XYZ ”” is “VOD”, the broadcast content recording management unit 219 sets the access destination of the line “drama“ XYZ ”” in the recorded content management table 232. The described URI “URI: http: //www.***” is output to the control unit 212. The control unit 212 causes the communication unit 213 to access the storage location of the VOD distribution server 3 indicated by the URI. Further, the communication unit 213 receives “drama“ XYZ ”” redistributed by VOD. In addition, the VOD processing unit 216 acquires data of recorded content redistributed by VOD from the communication unit 213, and starts a reproduction process of recorded content redistributed by VOD.

  Note that if the recording type of the detected recorded content is “recording”, the broadcast content recording management unit 219 accesses the access destination described in the “drama“ XYZ ”” line of the recorded content management table in S54. Is output to the control unit 212. The control unit 212 causes the broadcast content reproduction unit to reproduce the broadcast content stored in the storage unit 215 using the access destination.

  Note that the storage unit 215 deletes the stored recorded content when the designated broadcast content recording period has passed. With the above operation, the operation of the digital broadcast receiving apparatus 2 according to Embodiment 1 is completed.

  Note that the broadcast content recording management unit 219 according to Embodiment 1 may determine the necessity of recording based on information in the storage capacity monitoring unit 215a.

It may be. With this configuration, the digital broadcast receiving device 2 according to Embodiment 1 records all recorded content when the storage capacity of the storage unit 215 is sufficiently large, so that more VOD redistributed content than necessary. Communication costs can be reduced, and the use of the communication network 5 can be restricted to reduce the communication cost.

  In the digital broadcast receiving apparatus 2 according to the first embodiment, when the broadcast content recording management unit 219 is configured to determine whether recording is necessary based on the information of the storage capacity monitoring unit 215a, the recording of the recorded content is performed. It is also assumed that the storage capacity of the storage unit 215 is insufficient. In this case, among the recorded contents currently recorded in the storage unit 215, the recorded contents whose broadcast content recording period is included in the broadcast content distribution period can be deleted. With this configuration, it is possible to record the recorded content even when the storage capacity is insufficient during recording.

  Furthermore, in the digital broadcast receiving apparatus 2 according to Embodiment 1, there may be a case where the broadcast content distribution period is divided into a plurality of times during the broadcast content recording period. Normally, in such a case, the broadcast content recording management unit 219 determines that the recording type is “recording”, but the broadcast content recording management unit 219 once records the recording content to be recorded, and redistributes it by VOD. It is also possible to configure such that the recorded content is deleted when the broadcast content can be viewed. Thereby, the user can prevent the recorded content from being overlooked. Furthermore, the storage capacity of the storage unit 215 can be used effectively.

  Although the digital broadcast receiving apparatus 2 according to Embodiment 1 receives broadcast content redistributed by VOD by the communication unit 213, the digital broadcast receiving apparatus 2 is not limited to VOD but via a communication network 5 such as the Internet. Any broadcast content may be distributed.

  Further, the digital broadcast receiving apparatus 2 according to Embodiment 1 has shown an example in which the VOD redistribution schedule information is described in the EIT information. However, the present invention is not limited to this, and information that can describe the broadcast content distribution period such as SDT information. If so, the VOD redistribution schedule information may not be described in the EIT information.

  Furthermore, in the digital broadcast receiving apparatus 2 according to the first embodiment, the example in which the VOD redistribution schedule information is composed of Event_ID, date, broadcast content name, broadcast content distribution period, URI, and contract ID is shown. Not limited to this, it may be composed only of a URI. For example, the digital broadcast receiving apparatus 2 describes only the URI that is the access destination of the broadcast content redistributed by VOD in the EIT information, and broadcasts the broadcast content redistributed by VOD by accessing this URI. A content distribution period or the like may be acquired.

  The digital broadcast receiving apparatus 2 according to Embodiment 1 has a configuration in which the antenna 201 and the communication unit 213 (the antenna 201 and the communication unit 213 are collectively referred to as a broadcast content information receiving unit) are provided inside. May be provided.

  In the description of the broadcast content recording management unit 219 according to the first embodiment, the reserved content management table and the recorded content management table are composed of Event_ID, date, broadcast content name, broadcast content distribution period, URI, and contract ID. However, any information included in any of SI information, EIT information, and VOD redistribution schedule information can be additionally managed. For example, it is possible to add a start time, a broadcasting station name, or the like. The reserved content list and the recorded content list can also be added as long as they are information included in either SI information or EIT information VOD redistribution schedule information.

  Furthermore, in the digital broadcast receiving apparatus 2 according to Embodiment 1, the broadcast content recording period is configured to be designated according to the type of recorded content to be recorded in advance on the broadcast content recording period setting screen. The present invention is not limited to this, and it is also possible to configure so as to be specified in detail for each recording content to be reserved for recording. The format of the broadcast content recording period setting screen is not limited to this, and a specific date may be input.

  In the digital broadcast receiving apparatus 2 according to the first embodiment, the broadcast content recording management unit 219 compares the broadcast content recording period with the broadcast content distribution period, and the broadcast content recording period not included in the broadcast content distribution period. When it exists, it was determined as recording, otherwise it was determined as VOD. The present invention is not limited to this, and the broadcast content recording period may be determined to be recorded when the number of days in the period not included in the broadcast content distribution period is equal to or less than a predetermined threshold. For example, the broadcast content recording management unit 219 compares the broadcast content recording period with the broadcast content distribution period, and records the recorded content if the broadcast content recording period is not included in the broadcast content distribution period within 5 days. Instead, it is possible to reproduce the broadcast content redistributed by VOD.

  In the digital broadcast receiving apparatus 2 according to the first embodiment, the broadcast content distribution period is managed by date, but is not limited to this, and may be managed by time. For example, the broadcast content distribution period may be expressed by adding time such as “2012/12/4 15: 00-2013 / 2/10 17:00”.

  Further, the digital broadcast receiving apparatus 2 according to the first embodiment receives the broadcast content redistributed by VOD in the streaming format, but is not limited thereto, and may be received in the download format. When the digital broadcast receiving apparatus 2 receives the data in the download format, the storage unit 215 stores the broadcast content data redistributed by the VOD received from the communication unit 213.

  As described above, in the digital broadcast receiving apparatus 2 according to Embodiment 1, the broadcast content recording management unit 219 determines that the recording is a recording when there is a broadcast content recording period that is not included in the broadcast content distribution period. In this case, it is determined as VOD. Therefore, the user can select recording of the recorded content or VOD without considering the broadcast content distribution period.

  In the digital broadcast receiving apparatus 2 according to the first embodiment, the broadcast content recording management unit 219 determines that the recording is performed when there is a broadcast content recording period that is not included in the broadcast content distribution period, and otherwise. Since it is determined as VOD, the amount of data for storing the recorded content in the storage unit 215 is reduced, and the storage capacity can be used effectively.
