Description

  The present invention relates to a broadcast receiving apparatus and a broadcast receiving method for receiving broadcast data, and more particularly, to a broadcast receiving apparatus and a broadcast receiving method for receiving broadcast data including data of a plurality of programs on a single channel.

  In recent years, in digital broadcasting using terrestrial, satellite broadcasting, cable networks, or the like, data broadcast on a physical channel related to a specific frequency may be broadcast including data of a plurality of programs. This is called “multi-organization”, “multi-channel”, or the like, that is, it is possible to increase the number of channels by digital broadcasting.

  For example, in terrestrial digital broadcasting, a broadcasting band that can broadcast one high-resolution program is assigned to one physical channel, but this broadcasting band is divided into two to three bands. Then, a plurality of programs with resolutions that can be broadcast in each of the divided bands are broadcast.

  A plurality of programs broadcast on such a specific physical channel are associated with an organized channel which is a channel below the physical channel. Note that a plurality of programs simultaneously broadcast on each organization channel in the multi organization may be the same (that is, the event is shared) or different.

  In addition, the user of the broadcast receiving apparatus can select not only a physical channel received by the broadcast receiving apparatus but also a specific organized channel from a plurality of organized channels below the physical channel.

  For example, a method is generally used in which a reception operation of a specific physical channel or organization channel is assigned to a channel button provided on a remote controller used for operation of the apparatus and used for selection of a reception channel. When assigning a specific physical channel to a channel button, it is common to assign the organization channel having the smallest channel number among the plurality of organization channels of the physical channel.

  That is, the user can select a channel button provided on the remote controller by pressing or the like so that the broadcast receiving apparatus receives a specific physical channel or organized channel.

  However, for example, when a user switches channels in units of physical channels, only a specific organized channel of the switched physical channel is received, so even if a different program is broadcast on each of a plurality of organized channels, it can be used. A person cannot select a program of all organized channels.

  In addition, when the user switches channels in units of organized channels, all the organized channels are received, so even if the same program is broadcast on each of the plurality of organized channels, the same program is selected continuously. Will be.

  That is, since it is difficult for the user to efficiently select the physical channel or the organization channel, a channel selection method that is convenient for the user is desired.

  For example, according to Patent Document 1, when a specific direct channel selection key on a remote controller is pressed, a channel selected for event sharing with a currently selected organization channel is skipped, and channel selection for switching to an organization channel not sharing an event is performed. The method of operation is open to the public.

JP 2008-263534 A (FIG. 4, paragraph 0040)

  However, according to the technique disclosed in Patent Document 1, when a specific direct channel selection key on the remote controller is sequentially pressed, depending on whether or not there is a knitting channel that shares an event with the currently selected knitting channel, the corresponding knitting channel is skipped. Alternatively, since the selection method is used, the presence / absence of event sharing related to the organization channel is gradually notified to the user by pressing the direct channel selection key.

In other words, this is not a technique for conveniently presenting information related to the presence / absence of event sharing related to the organization channel to the user.
Therefore, in order to solve the above-described problems, the present invention has an object to provide a broadcast receiving apparatus and a broadcast receiving method capable of conveniently presenting information related to the presence / absence of event sharing related to an organized channel to a user. And

  In order to solve the above-described problems, the present invention obtains broadcast data provided by multiplexing a plurality of program data broadcasted as a plurality of organized channels in a specific physical channel, and the obtaining unit includes: Output means for outputting a video of a program based on program data of a selected organization channel among the plurality of program data multiplexed with the broadcast data to be acquired, and the selected organization output by the output means A presentation means for presenting information related to the other organization channel simultaneously with the video when there is another organization channel in addition to the selected organization channel when displaying the video of the program of the channel. It is characterized by this.

  Further, in order to solve the above-described problems, the present invention acquires broadcast data provided by multiplexing a plurality of program data broadcasted as a plurality of organized channels in a specific physical channel, and the acquired broadcast data When outputting the video of the program based on the program data of the selected organization channel among the plurality of program data to be multiplexed, and displaying the video of the program of the selected organization channel that has been output, When there is another knitting channel in addition to the selected knitting channel, information on the other knitting channel is presented simultaneously with the video.

In the channel information, numerical information “1” to “12” corresponding to each numeric key is defined as channel selection key information associated with the numeric key of the tuning key 203 such as the remote controller RC. Further, each channel selection key information includes a physical channel number that is a channel number assigned to each broadcasting station, a broadcasting station name, a (transmission / reception) frequency related to the broadcasting of the broadcasting station, Information such as the organization channel number which is the number of the hierarchical channel is associated.

  Specifically, for example, with respect to the numerical information “1” corresponding to the numeric key “1” of the channel selection key 203, the physical channel number “27” broadcasted with the (transmission / reception) frequency “# 01” [MHz]. Is associated with the broadcasting station name “Broadcasting Station 1”. Since this physical channel has organization channels “011”, “012”, “013” as lower hierarchical channels, the numeric key “1” further includes three organization channel numbers “011”, “012”. "," 013 "are also associated with each other.

  For example, in terrestrial digital broadcasting, one physical channel is a standard that can be multi-organized with a maximum of eight knitting channels as a broadcast program for a television receiver. Therefore, in a specific time zone, there are three broadcasting channels such as “Broadcasting Station 1” and “Broadcasting Station 4”, “Broadcasting Station 2”, “Broadcasting Station 12”, and “Broadcasting Station 1” and “Broadcasting Station 4”. There are simultaneously broadcast stations having organized channels, and broadcast stations having 8 organized channels such as “Broadcast Station 3”.

That is, the number of knitting channels included in each physical channel is different for each physical channel and is not a fixed number.
Next, a program guide based on the channel information shown in FIG. 4 will be described with reference to FIG. FIG. 5 is a diagram showing a part of a specific example of the program guide based on the channel information shown in FIG.

  Note that the program table shown in FIG. 5 shows the programs broadcast from 08:00 to 11:00 on the knitting channels “011”, “012”, and “013” of “Broadcasting Station 1” in time series. It is what was presented.

  Specifically, at the time of 08:10, program 1 (golf) is broadcast on all of the composition channels “011”, “012”, and “013”, that is, the composition channels “011” and “012”. "," 013 "share the event.

  At 09:10, program 2 (soccer) is broadcast on “011”, and program 3 (drama) is broadcast on two channels “012” and “013”, that is, “012” and “013”. "Is sharing events.

  Further, at 10:40, program 2 (soccer) is broadcast on “011”, program 4 (news) is broadcast on “012”, and program 5 (movie) is broadcast on “013”. Does not share events.

  That is, as in the program table shown in FIG. 5, the same program is broadcast (event sharing) or different programs are broadcast on a plurality of organized channels of a specific physical channel. The sharing state changes according to the time zone.

  Next, the non-event shared list that is updated by the composition channel analysis unit 305 and stored in the non-event shared list storage unit 312 will be described with reference to FIG. FIG. 6 is a diagram illustrating a specific example of the non-event sharing list.

  In the non-event sharing list, a plurality of organized channels of a specific physical channel are divided into groups based on the contents of the program currently being broadcast, and a representative channel is determined for each divided group. A list associated with channel numbers. That is, the non-event sharing list is a list in which organized channels that are not sharing events are specified.

  Specifically, FIG. 6 shows a specific example of the non-event sharing list related to the broadcast station name “broadcast station 1” of the physical channel number “27” broadcasted with the (transmission / reception) frequency “# 01” [MHz]. ing. The physical channel “27” (“Broadcasting Station 1”) has three organized channels “011” to “013”.

  FIG. 6A is an example at the time 08:10 in FIG. 5 and shows a state in which the program 1 is being broadcast on the composition channels “011” to “013”. First, the composition channel analysis unit 305 monitors and analyzes the state of event sharing among the composition channels, and divides the three composition channels into groups. Then, the organization channel analysis unit 305 generates a non-event sharing list in which the organization channel with the smallest channel number in the group is the representative channel. In other words, a non-event shared list in which a number is assigned to the organization channel “011”, which is a representative channel of a group composed of three organization channels sharing one program event, is generated and the non-event sharing list storage unit 312 is generated. Is remembered.

  Next, FIG. 6B is an example at the time 09:10 in FIG. 5, in which program 2 is broadcast on organization channel “011” and program 3 is broadcast on organization channels “012” to “013”. It is. At this time, the organization channel analysis unit 305 monitors and analyzes the state of event sharing between the organization channels in the same manner as in FIG. 6A, and analyzes each of the groups of organization channels sharing each event of the two programs. A non-event shared list in which numbers are sequentially assigned to the organization channels “011” and “012”, which are representative channels, is generated and stored in the non-event shared list storage unit 312.

  Further, FIG. 6C shows an example at 10:40 in FIG. 5, where program 2 is broadcast on organization channel “011”, program 4 is on organization channel “012”, and program 5 is broadcast on organization channel “013”. It is a state that has been. At this time, similarly to FIGS. 6A and 6B, the organized channel analysis unit 305 monitors and analyzes the state of event sharing between the organized channels, and organizes channels that share each of the three programs. A non-event shared list in which numbers are sequentially assigned to the organization channels “011”, “012”, and “013”, which are representative channels for each group, is generated and stored in the non-event shared list storage unit 312.

  In addition, although the composition channel analysis part 305 demonstrated embodiment which produces | generates the non-event sharing list which numbered each representative channel for every group of the composition channel which is sharing an event in order, numbering is carried out in order. Instead, an embodiment may be used in which a non-event shared list with an identifiable identifier is generated.

  That is, the organized channel analysis unit 305 monitors and analyzes the current event sharing state between the organized channels, confirms whether or not there is event sharing for each organized channel, and updates the non-event sharing list.

Next, with reference to FIG. 7, a process of presenting information related to the organization channel included in the same physical channel as the channel being viewed will be described.
FIG. 7 is a flowchart for explaining processing for presenting information related to the organization channel included in the same physical channel as the channel being viewed.
First, the channel selection unit 301 determines whether or not a specific numeric key of the channel selection key 203 provided on the operation unit 51 or the remote controller RC is pressed (S701). As a result of this determination, if it is determined that the button has been pressed (Y in S701), the channel selection unit 301 refers to the channel information storage unit 311 and displays the currently pressed key on the display 61. It is determined whether or not the physical channel number or the organization channel number that broadcasts the broadcasted program is associated (S702).

  If it is determined by this determination that they are associated (Y in S702), the channel selection unit 301 stores channel information based on the organization channel number that is currently broadcasting the displayed program. With reference to the section 311, a specific knitting channel is selected and switched in a predetermined order from the knitting channels associated with the pressed numeric key (S703). Then, the channel information extraction unit 303 newly extracts channel information from the input data and newly stores, that is, updates in the channel information storage unit 311 (S705).

  On the other hand, if it is determined that there is no channel associated with the pressed numeric key (S702), it is determined that the channel is not associated (N in S702), the channel selection unit 301 is currently displayed. The physical channel associated with the pressed numeric key is specified with reference to the channel information storage unit 311 based on the organization channel number that is broadcasting the program. Further, the channel selection unit 301 selects and switches the main channel that is the organization channel having the smallest channel number among the organization channels of the identified physical channel (S704). Then, the channel information extraction unit 303 newly extracts channel information from the input data, and updates the channel information storage unit 311 (S705).

  As a result of determining whether or not a specific numeric key has been pressed (S701), if it is determined that it has not been pressed (N in S701), the channel information extraction unit 303 broadcasts the currently displayed program. It is determined whether or not the program organization of the current physical channel has been changed (S710). As a result of this determination, if it is determined that the change has not been made (N in S710), a determination is again made as to whether or not a specific numeric key has been pressed (S701). On the other hand, if it is determined as a result of the determination of whether or not the program organization has been changed (S710) (Y in S710), the channel information extraction unit 303 newly extracts channel information from the input data, The information storage unit 311 is updated (S705).

  When the channel information extraction unit 303 updates the channel information storage unit 311 in any one of the processing procedures (S705), the composition channel analysis unit 305 refers to the channel information storage unit 311 and currently displays the display unit. It is determined whether or not the physical channel broadcasting the program displayed in 61 has a plurality of organization channels (S706).

  If it is determined as a result of determining whether or not it has a plurality of organization channels (S706) (Y in S706), the organization channel analysis unit 305 stores the channel information in the channel information storage unit 311. Based on the received channel information and the program related information input from the channel information extraction unit 303, the organized channels sharing the event are distinguished into the same group (S707).

  Then, the composition channel analysis unit 305 newly generates a non-event shared list by specifying a representative composition channel number for each distinguished group, and newly generates this non-event shared list storage unit 312. The non-event sharing list is updated (S708). Further, the organized channel analysis unit 305 reads the non-event shared list with reference to the non-event shared list storage unit 312, and outputs information about the organized channel to the OSD generating unit 304 based on the read non-event shared list. . Then, the OSD generation unit 304 generates an OSD that presents information related to the corresponding knitting channel based on the information related to the knitting channel input from the knitting channel analysis unit 305, and outputs the OSD to the display 61. This OSD is displayed (S709).
