Description

  The present invention relates to a broadcast receiver, a program information acquisition method for the broadcast receiver, and a program.

  In terrestrial digital broadcasting, broadcast data (signal) is transmitted along the MPEG-2 system (Systems). The MPEG-2 system is a digital broadcasting multiplex system.

  The broadcast station transmits TS (Transport Stream) data as a broadcast signal. This TS data is stream data configured by multiplexing video / audio / additional data and dividing it into fixed-length packets called TS packets.

  As shown in FIG. 13, the TS packet is composed of three pieces of data: a TS header, an adaptation field, and a payload. The TS header defines a packet identifier for identifying a TS packet.

  The adaptation field stores time information necessary for synchronous reproduction of video / audio. The payload stores video / audio / additional data.

  Data stored in the payload is roughly divided into two types of data: data that requires synchronous reproduction on the receiving device side and additional data that does not require synchronous reproduction.

  Video data, audio data, subtitle data, and the like are stored in the payload of the TS packet in the data format called PES (Packetized Elementary Stream) as the former data that requires synchronous reproduction.

  Data such as EIT (Event Information Table) and data broadcasting is data that does not require synchronous reproduction, and is stored in the payload of the TS packet in a data format called section.

  The EIT is information necessary for configuring the program guide, and the digital broadcast receiver that receives the broadcast data acquires the program information by analyzing the EIT stored as section data in the TS packet.

  Next, in terrestrial digital broadcasting, one channel is divided into 13 segments and transmitted, and among the 13 segments, broadcasting using one central segment is “1 segment (segment) broadcasting”, Broadcasting using 12 segments is called “12-segment broadcasting”.

In 12-segment broadcasting, high-quality data can be transmitted, but since reception stability is low, it is used as broadcasting for fixed receivers, for example. Although 1-segment broadcasting cannot transmit high-quality data, it has high reception stability and is used, for example, as a broadcast for portable receivers.

  EITs for 12-segment broadcasting and 1-segment broadcasting are referred to as H-EIT and L-EIT, respectively.

  The H-EIT includes information such as program title, outline, detailed explanation, broadcast date and time, video and audio data format, limited viewing information and series information as program information for eight days.

  A 12-segment broadcast receiver capable of receiving 12-segment broadcasts uses this H-EIT to realize functions such as program search, recording and viewing reservation, recording content management and search, and so on. It has improved.

  On the other hand, the L-EIT has a smaller amount of information than the H-EIT, and some of the data included in the H-EIT does not include part of detailed information and series information.

  Further, the maximum number of events transmitted by L-EIT is 10, and the broadcasting station transmits only the program information of up to 10 programs thereafter including the currently broadcasted program.

  For this reason, a digital broadcast receiver that can only receive 1-segment broadcasting (hereinafter referred to as “1-segment broadcasting receiver”) can perform content management and search only within the range of this L-EIT. .

  Therefore, the program information received by the 1-segment broadcast receiver and the H-channel received by the 12-segment broadcast receiver can be managed and searched in the 1-segment broadcast receiver in the same manner as the 12-segment broadcast receiver. There is a digital broadcast receiver integrated with EIT (see, for example, Patent Document 1).

  In this digital broadcast receiver, the H-EIT acquired by the 12-segment broadcast receiver is stored in the recording device on the 1-segment broadcast receiver side via the recording medium, or the H-EIT is acquired using a cable. The 1-segment broadcasting receiver integrates program information received by both digital broadcasting receivers.

For this reason, work becomes complicated and program information cannot be integrated in real time.

  The program information combination record management unit 18 determines whether the 12-segment broadcast and the 1-segment broadcast are simultaneous broadcasts based on the 12-segment broadcast program information and the 1-segment broadcast program information supplied from the signal separation unit 13. judge.

  There are various methods for this determination. For example, the first method is a method of comparing program information of 12-segment broadcasting, title data described by text data in the program information of 1-segment broadcasting, performers of the program, and the like.

  The program information combination record management unit 18 determines that the broadcast is a simulcast if the title data matches or the performers of the program match, and if it does not match, it determines that the broadcast is not a simulcast.

  The second method is a method of analyzing images of both video data of 1-segment broadcasting and 12-segment broadcasting, or analyzing both audio data and comparing the analysis results. If the analysis results match, the program information combination record management unit 18 determines that the broadcast is simultaneous, and if the analysis results do not match, the program information combination record management unit 18 determines that the broadcast is not simultaneous.

  The program information combination record management unit 18 is information that is different from the program information of 1 seg broadcast and is specialized for 12 seg broadcast among the program information of 12 seg broadcast in order to suppress the amount of program information to be stored. Information that is effective for searching and managing 1-segment recorded content recorded in 1-segment broadcasting is combined with the program information of 1-segment broadcasting.

  Information that is effective for searching and managing 1-segment recorded content includes, for example, “extended format event descriptor” and “series descriptor” defined in the program sequence information standard ARIB STD-B10. .

  The program sequence information standard ARIB STD-B10 is a standard used for the digital broadcasting of the Japan Radio Industry Association. The “extended format event descriptor” is information indicating detailed information of a program, and the “series descriptor” is information used for identifying a series program.

  In the present embodiment, the program information combination record management unit 18 includes program information described in the 1-segment broadcast L-EIT, the “extended format event descriptor”, the “series descriptor” of the 12-segment broadcast, Shall be combined.

  However, the program information combination record management unit 18 may combine all 1-segment broadcast program information and all 12 broadcast program information.

  The program information combined record management unit 18 stores the one-segment recorded content and the combined program information in the storage device 14 in association with each other.

  As a method of storing 1-segment recorded content and combined program information in association with each other, for example, there is a method of re-multiplexing 12-segment recorded content and combined program information into MPEG2-TS and storing it as TS data.

  As another method, there is a method of describing the file name of the recorded content in the combined program information. In this case, by referring to the combined program information, it is possible to specify the 1-segment recorded content file.

  As described above, the program information combined recording management unit 18 stores the one-segment recorded content and the combined program information in the storage device 14 in association with each other, and manages the one-segment recorded content using the combined program information.

  The program search unit 19 displays an EPG (Electronic Program Guide) on the monitor 111 and searches for a content desired by the user using a list of recorded program data.

  The program search unit 19 classifies the attributes included in the combined program information to make content search easy, and further stratifies and creates a folder of 1-segment recorded content for each attribute.

  For example, as shown in FIG. 6, the program search unit 19 classifies the attributes into “performers”, “directors”, and “series” with the root point P0 as the highest folder hierarchy, and includes these attributes. A classification folder F11 is created.

  Next, the program search unit 19 subdivides the attribute “performer” of the large classification folder F11 into the attributes “Actor A” and “Actor B”, and includes a small classification folder including these attributes “Actor A” and “Actor B”. F21 is created.

  Then, the program search unit 19 creates a folder for the attribute “Actor A” classified in the small classification folder F21, refers to the combined program information, and performs the actor A appearance as 1-segment recording content in which the actor A appears. Contents 1, 2,..., 5 are arranged in this folder.

  Similarly, the program search unit 19 creates a folder for the attribute “Actor B” classified in the small classification folder F21, and refers to the combined program information, and arranges the 1-segment recorded content in which the actor B appears in this folder. To do.

  Furthermore, the program search unit 19 creates a small classification folder F22 including attributes “director A” and “director B”, which are subdivided attributes “director” of the large classification folder F11, and attribute “series” of the large classification folder F11. A small classification folder F23 including the attributes “drama A” and “drama B” which are subdivided. Then, the program search unit 19 arranges one segment recorded content in each of the small classification folders F22 and F23.

  In this way, by classifying the attributes included in the combined program information, and further creating a folder of one segment recorded content for each attribute, various classification of one segment recorded content becomes possible, and a huge number of segments are recorded. Even when one segment recorded content is recorded, it is easy to search for the content.

  When the “search” operation information is supplied from the user operation unit 113 after the folder having such a configuration is created, the program search unit 19 uses the combined program information to select one segment recorded content selected by the user. Acquire attributes and search each created folder based on the acquired attributes. And the program search part 19 specifies this 1 segment recording content.

  When the one-segment recorded content is specified, the program search unit 19 stores data indicating the storage location of the specified one-segment recorded content in a search result storage area secured in advance in the storage device 14.

Next, the operation of the digital data receiver 1 according to the first embodiment will be described.
If the user presses and holds down the power key 121 of the user operation unit 113 when the power is off, the user operation unit 113 receives this operation information and the mobile phone 101 turns on the power. That is, the cellular phone 101 supplies a drive current by applying a voltage to the digital broadcast receiver 1 and each unit. The digital broadcast receiver 1 starts operating when supplied with a drive current.

  When the user operates the menu key 123 and the cursor key 124 of the user operation unit 113 and selects “view current broadcast program” shown in FIG. 4, the user operation unit 113 receives this operation information and sends it to the digital broadcast receiver 1. Supply.

The display processing unit 16 supplies the supplied data broadcasting data to the monitor 111, and the monitor 111 performs screen display of the data broadcasting based on the supplied data broadcasting data.

  In the case of 12-segment PES data or 1-segment PES data, the signal separation unit 13 supplies the separated 12-segment PES data or 1-segment data to the AV data reproduction unit 15.

  The AV data reproduction unit 15 sends the reproduced video data to the display processing unit 16 and the audio data to the speaker 112 for the data such as video / audio stored in the 12-segment PES data or the 1-segment PES data. To do.

  The display processing unit 16 sends video data that has been decoded for display to the monitor 111, the monitor 111 displays video based on the sent video data, and the speaker 112 supplies the supplied audio data. Output sound based on.

  When the user operates the menu key 123 and the cursor key 124 of the user operation unit 113 to select “recording” shown in FIG. 4, the user operation unit 113 supplies this operation information to the digital broadcast receiver 1.

  When the operation information is supplied, the digital broadcast receiver 1 reads the program data from the storage device 14 and executes the recording process according to the flowchart shown in FIG.

  The digital broadcast receiver 1 starts 1-segment broadcast recording (step S11). The receiving unit 12 receives and demodulates a broadcast signal of 1-segment broadcasting via the antenna 11 and supplies the generated 1-segment TS data to the signal separation unit 13.

  The signal separation unit 13 demultiplexes the 1-segment PES data and the 1-segment section data from the 1-segment TS data supplied from the reception unit 12, and supplies the separated 1-segment PES data to the AV data recording management unit 17.

  The AV data recording management unit 17 stores the 1-segment PES data supplied from the supplied signal separation unit 13 in the storage device 14.

  In addition, the signal separation unit 13 supplies the L-EIT acquired from the 1-segment section data to the program information combination record management unit 18. The program information combination record management unit 18 accumulates L-EIT as program information of 1-segment broadcasting, and extracts information related to the program being recorded from the L-EIT.

  The digital broadcast receiver 1 starts reception of 12-segment broadcasting on the same channel as 1-segment broadcasting (step S12). Similarly, the receiving unit 12 demodulates a broadcast signal of 12-segment broadcasting and supplies the generated 12-segment TS data to the signal separation unit 13.

  The signal separation unit 13 demultiplexes the 12-segment PES data and the 12-segment section data from the 12-segment TS data supplied from the reception unit 12, and supplies the separated 12-segment PES data to the AV data recording management unit 17.

  In the folder structure as shown in FIG. 6, “Actor A” is arranged in the small classification folder F21, and “Actor A appearance content 1” to “Actor A appearance content 5” are arranged in the folder of “Actor A”. ing.

  As a result of the search, the program search unit 19 identifies “Actor A Appearance Content 1” to “Actor A Appearance Content 5”, and stores this 1-segment recorded content “Actor” in the search result storage area reserved in the storage device 14 in advance. Data indicating the storage locations of “A Appearance Content 1” to “Actor A Appearance Content 5” is stored.

  Further, as shown in FIG. 8A, the monitor 111 displays “Actor A Appearance Content 1” to “Actor A Appearance Content 5” in the search result display column as a list of searched content titles, and below that. Displays the number of hits. Further, the monitor 111 displays program information items on the monitor 111 for each hit content.

  When the user refers to the title list and operates the cursor key 124 of the user operation unit 113 to select “program information” of “Actor A appearance content 1”, the user operation unit 113 accepts this operation information. To the digital broadcast receiver 1.

  When this operation information is supplied to the digital broadcast receiver 1, the monitor 111 displays combined program information of “Actor A Appearance Content 1” as shown in FIG. 8B.

  This program information includes the program title, summary, broadcast date and time, video / audio data format, limited viewing information, detailed information, and series information. The detailed information and the series information are program information described only in the 12-segment broadcasting H-EIT.

  When the user operates the cursor key 124 of the user operation unit 113 and selects “RETURN”, the monitor 111 displays the keyword search screen shown in FIG. 8A again.

  When the user operates the cursor key 124 of the user operation unit 113 to select “Actor A Appearance Content 1” and select “View Recorded Program” shown in FIG. 4, the user operation unit 113 accepts this operation information. To the digital broadcast receiver 1.

  When this operation information is supplied to the digital broadcast receiver 1, the program search unit 19 stores the specified 1-segment recorded content “Actor A Appearance Content 1” in the search result storage area reserved in the storage device 14 in advance. Stores data indicating the location.

  The AV data playback unit 15 acquires data indicating the storage location of the 1-segment recorded content “Actor A Appearance Content 1” from the search result storage area, and based on the acquired data, the 1-segment recorded content “ Actor A appearance content 1 ”is acquired.

  The AV data reproduction unit 15 decodes the acquired “Actor A Appearance Content 1” and supplies it to the display processing unit 16. The display processing unit 16 supplies the video data to the monitor 111 and the audio data to the speaker 112. To supply.

  The monitor 111 displays the video of the “Actor A Appearance Content 1” based on the supplied video data, and the speaker 112 outputs this audio based on the supplied audio data.

  As described above, according to the first embodiment, when the program information combined record management unit 18 creates combined program information, it also receives 12-segment broadcast program information.

  Therefore, more detailed program information can be easily acquired in real time.

  Also, when recording 1-segment broadcasting, the program information of 12-segment broadcasting that is being broadcast simultaneously is acquired, and items that can be used for the program information of 1-segment recorded content are extracted from the program information. The program information is combined with the program information and the combined program information is created.

  Thus, by omitting information specialized for 12-segment broadcasting from the program information of 12-segment broadcasting, the amount of program information stored in the storage device 14 can be suppressed.

(Embodiment 2)
The digital broadcast receiver according to the second embodiment acquires program information of 12-segment broadcasting before starting recording of 1-segment broadcasting, and creates combined program information.

  In particular, when a plurality of programs are scheduled to be recorded, the 12-segment broadcast program information is acquired by acquiring the 12-segment broadcast program information of the same channel and the same time period before the recording of the 1-segment broadcast is started. Can be acquired in a batch.

  In addition, not only the program information reserved for recording but also the 12-segment broadcast program acquired in advance, the information acquired for searching for the program scheduled to be broadcast can be used.

  Therefore, the program information reception control unit 20 sets the 12-segment broadcast reception channel to the channel CH2 on which the 1-segment program C is broadcast (step S30), and the digital broadcast receiver 1 sets 1 of the channel CH2. The program information of the 12 segment program C in the same time zone corresponding to the segment program C is received.

  When the 1-segment program C and the 12-segment program C are simulcast programs (step S26; Yes), the program information combination record management unit 18 displays combined program information of the 1-segment program C and the 12-segment program C. Generate (step S27).

  The program information combination record management unit 18 stores the generated combined program information of the 1-segment program C in the storage device 14, and stores the information “save” indicating the storage in the reserved channel list as shown in FIG. Registration is performed (step S28).

  Next, when the program information reception control unit 20 refers to the reserved channel list, all program information of 12 segment programs corresponding to 1 segment broadcasting is acquired (step S29; No). Therefore, the program information reception control unit 20 ends this reception control process.

  After the program information reception control unit 20 executes the reception control process in this way, the digital broadcast receiver 1 sets the 1-segment program A at the reservation time 6:00 to 7:00 and the reservation time 7:00, respectively. Record 1-segment program B at -8: 30, and record 1-segment program C at reservation times 9: 00-11: 00.

When the user operates the menu key 123 and the cursor key 124 of the user operation unit 113 to select, for example, the 1-segment program A in the reserved channel list, the user operation unit 113 sends this operation information to the digital broadcast receiver 1. Supply.
