However, in digital broadcasting, the channel selection section takes time to select because of the de-interleaving processing that is unique to digital broadcast signal processing, etc. You have to wait for a reasonable amount of time before you can be.
Techniques for reducing such waiting time have also been proposed. In one proposal, a channel is selected with an RF signal as an input, and a TS (transport stream) of the channel is output, each of which selects a different channel, and outputs of each of the channel selection units A selection unit for selecting one of these and outputting TS, a channel selection storage unit for storing channel selection information selected by each channel selection unit and receivable station information, and operation information from a receiver input The channel selection storage unit, a plurality of channel selection units, and a channel selection control unit that controls the selection unit are configured as a digital broadcast channel selection apparatus.

In this configuration, when switched on, all receivable channels are selected by each channel selection unit. For receivable channels, refer to receivable station information set in the channel selection storage unit, or if receivable station information is not set, information is acquired from data broadcasting and a receivable flag is set. The channel number selected by each channel selection unit and the corresponding information of the channel selection unit are set in a predetermined area of the channel selection storage unit. When operation information related to channel selection is input, the channel number of the channel selection storage unit and the correspondence information of the channel selection unit are referred to, and the output of the channel selection unit that selects the channel is selected by the selection unit. (See Patent Document 1).

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings to be referred to below, for the sake of convenience, the main part that is the subject of the description is exaggerated as appropriate, and other than the main part is appropriately simplified or omitted.
FIG. 1 is a block diagram showing a configuration of a digital broadcast receiving apparatus as an embodiment of the present invention. In the digital broadcast receiving apparatus according to the present embodiment, for example, each RF signal from an antenna circuit or the like is supplied, and channel selection processing related to digital broadcast is performed in parallel at the same time by performing different channel selection. , First channel selection unit 101, second channel selection unit 102,..., N-th channel selection unit (100 + n), a plurality of n channel selection units (representative code 100) are provided.

  A TS (transport stream) is obtained by each channel selection process by the n channel selection units 100. Each TS output obtained by the plurality of channel selection units 100 (101, 102,..., 100 + n) is supplied to the temporary storage management unit 200. In the temporary storage management unit 200, the data broadcast content information part is separated from each TS output supplied from the plurality of channel selection units 100 (101, 102,..., 100 + n), and the separated data broadcast content information part and each The corresponding original TS is stored in a predetermined temporary storage device 210 such as a hard disk device (HDD) for each corresponding channel.

  Channel selection for managing the operation of each of the plurality of channel selection units 101, 102,... (100 + n) and accessing the temporary storage device 210 via the temporary storage management unit 200 to read out the required data broadcast content information or the original TS. A control unit 300 is provided. A digital broadcasting service is provided to the viewer based on the data broadcasting content information read out in this way by the channel selection control unit 300 or the original TS.

  The channel selection control unit 300 is supplied with an operation signal from the operation unit 400 that receives an operation by the user of the digital broadcast receiving apparatus, recognizes the operation corresponding to the operation signal, and issues a command corresponding to the recognition. .., (100 + n) and the temporary storage management unit 200. In this way, the operation from the user (viewer) is recognized by the channel selection control unit 300, and the operation corresponding to this is executed. Note that a timer 310 is attached to the channel selection control unit 300, and a control operation according to a time schedule described later is executed based on the output of the timer 310.

  As described above, the temporary storage management unit 200 separates the data broadcast content information portion from each TS output from the plurality of channel selection units 101, 102,..., (100 + n), and the separated data broadcast content information portion. And the corresponding original TS are stored in a predetermined temporary storage device 210. The storage control is performed by the channel selection control unit 300 managing the temporary storage management unit 200, and the storage mode in the temporary storage device 210 is determined according to the data broadcasting content information portion and the corresponding original information for each corresponding channel. This is done by storing TS.

  Each data broadcast content information part separated from each TS output and each corresponding original TS are temporarily stored, and a ready state that can be used for the next use is prepared according to the machine. In this state, the channel selection control unit 300 is stored for each corresponding channel in the temporary storage device 210 via the temporary storage management unit 200 in response to, for example, a broadcast channel switching operation from the operation unit 400 by the user. The data block of the data broadcast content information portion of each TS that is present is selectively read out. Based on the read data, a prompt service can be provided to the user.

  The case where the broadcast channel switching operation is performed will be described in detail. When a broadcast channel switching operation signal issued from the operation unit 400 is supplied in response to the user performing a broadcast channel switching operation from the operation unit 400, the channel selection control unit 300 recognizes the broadcast channel switching operation. Then, a switching command corresponding to this recognition is issued to the channel selection units 101, 102,... (100 + n) and the temporary storage management unit 200.

  In response to this instruction, temporary storage management section 200 reads out a data block of the data broadcast content information portion of the TS related to the broadcast channel newly selected by the broadcast channel switching operation from temporary storage device 210. As described above, since the broadcast service for the user is performed based on the data block of the data broadcast content information part of the TS read from the temporary storage device 210, when the broadcast channel switching operation is performed, it is promptly performed without interposing the standby time. Broadcasting service will be started.

  In the embodiment of FIG. 1, there is provided an output selection unit 500 that selectively outputs one of the output TSs obtained by the channel selection processing of a plurality of channel selection units 101, 102,... (100 + n). Yes. One input terminal of the selection unit 500 has one obtained by a channel selection process in the first channel selection unit 101 as a predetermined channel selection unit among a plurality of channel selection units 101, 102,..., (100 + n). TS is supplied directly.

Also, at the other input terminal of the output selection unit 500, other TSs obtained by the channel selection processing of the other channel selection units 102,..., (100 + n) among the plurality of channel selection units are stored in the temporary storage management unit 200. Under management, the data is temporarily stored in the temporary storage device 210, selectively read from the temporary storage device 210, and supplied indirectly.
As described above, the output selection unit 500 temporarily receives the TS that is directly supplied as the output of the first channel selection unit 101 or the TS that is the output of the second to nth channel selection units 102,..., (100 + n). What is indirectly supplied after being stored in the storage device 210 (TS) is selectively output.

  Since the broadcast service for the user is performed based on the TS selectively output from the output selection unit 500 in this way, the broadcast channel switching operation is performed without any waiting time, and the first channel selection unit 101 Even if there is a situation in which the broadcasting service for the broadcasting channel after switching is not provided, the second to nth channel selection units 102,... Among the ones that are indirectly supplied after temporarily storing the TS, which is the output of the output, temporarily output the TS corresponding to the broadcast channel after the switching from the output selection unit 500, and apparently The broadcast service after switching can be provided promptly.

  In such an operation, in the output selection unit 500, when one TS is continuously obtained from the first channel selection unit 101, one TS is selected as its own output, and the supply of one TS is interrupted. In other words, the operation is performed by selectively outputting another TS that is indirectly supplied from the temporary storage device 210 under the management of the temporary storage management unit 200. When the supply of one TS is interrupted by the broadcast channel switching operation, the other TS is immediately output from the output selection unit 500 instead of this, so the provision of the broadcast service is interrupted even during the broadcast channel switching operation. There is no.

  As described above, the second to nth channel selection units 102,..., (100 + n) up to the time immediately before the broadcast channel switching operation are provided in order to provide promptly the broadcast service after the switching without interruption. The TS that is the output is stored in the temporary storage device 210 for an appropriate period, and prepared to appropriately respond to the read request according to the machine. In this case, even in a simple configuration in which the number of channel selection units is less than the number of broadcast channels scheduled for selection, the content selected by channel switching can be quickly displayed (that is, applicable). In the embodiment of the present invention, the following solution is applied in order to store data in the temporary storage device 210 and prepare it for reading). That is, the channel selection control unit 300 cyclically switches and selects from the second to nth channel selection units 102,..., (100 + n) among the plurality of channel selection units, and temporarily stores the contents of the different broadcast channels. The data is stored in the temporary storage device 210 under the management of 200. At this time, the tuning control unit 300 is configured such that a selection schedule for cyclically switching and selecting broadcast channels can be set as described above.

By appropriately setting this selection schedule, even if the configuration is such that the number of channel selection units installed in the digital broadcast receiving apparatus is less than the number of broadcast channels scheduled for selection. By switching broadcast channels cyclically, an apparatus that can handle the total number of scheduled broadcast channels is realized.
Next, an example of setting such a selection schedule will be described. For example, the channel tour schedule set in the channel selection control unit 300 ranks the channels in descending order of reception time by taking statistics related to the trend of reception time over a certain period of the viewer, etc. Stratification is performed on a plurality of hierarchies (5 layers in this example) as exemplified in the table.

即ち、一回の平均視聴時間と一週間の視聴時間の長さの順位とに注目して、最も受信時間の長い階層をＬ１（定常視聴チャンネル）、これに次いで長い階層をＬ２（単発視聴チャンネル）、更にそれに次ぐ長さの階層をＬ３（非定常視聴チャンネル）、一応選局は可能だが殆ど選ぶことのない階層をＬ４（選局可能チャンネル）とし、チャンネルとしては存在するが契約していない等の理由で当該デジタル放送受信装置では受信されない階層をＬ５（非選局チャンネル）といったようにランク付けを行う。

That is, paying attention to the average viewing time of one time and the ranking of the length of viewing time of one week, the layer with the longest reception time is L1 (steady viewing channel), and the layer with the longest reception is L2 (single viewing channel) ) In addition, the layer with the next length is L3 (unsteady viewing channel), and the layer that can be selected but is almost never selected is L4 (channel that can be selected). For example, the layer that is not received by the digital broadcast receiving apparatus is ranked as L5 (non-selected channel).

For each of the ranked hierarchies, the hierarchy L1 accumulates data broadcasts every time with a circulation frequency of once every five minutes. Hierarchy L2 sets the circulation frequency once every 5 minutes, and stores data broadcasts once every five minutes. Hierarchy L3 goes around once every 5 minutes, and hierarchy L4 goes around once every 15 minutes, and no data broadcast is stored. In addition, data-only broadcasting stores only the top 10 ranks.
Channel selection is controlled according to such a schedule, ST is stored in the temporary storage device 210 under the management of the temporary storage management unit 200, is selectively read out from the ST, and is output at the time of channel switching. Can be provided.

FIG. 2 is a diagram for explaining the operation of the embodiment of the present invention in comparison with a conventional example. FIG. 2A is a diagram illustrating the operation of the device that is a conventional example in Patent Document 1, and FIG. 2B is a diagram illustrating the operation of the device proposed in Patent Document 1, and FIG. These are figures showing the effect | action in embodiment of this invention.

It represents the period. The line labeled “data display” represents the time transition of the information reproduction status by the data of the data broadcast, and the solid line portion represents the display period and the broken line portion represents the display interruption period. Yes.

  In the conventional example of FIG. 2A, a period in which the video is interrupted for a while after the channel switching operation is continued, and during this period, a preparatory operation for projecting the broadcast channel after the channel switching is performed. The video service will be resumed. Regarding the reproduction status of information by data of data broadcasting, accumulation of information sufficient to provide a broadcasting service over a period longer than the period when the video is interrupted (ie, continuing the non-display state) After that, data broadcasting is resumed.

  In the device of Patent Document 1 in FIG. 2 (B), the video service is initially provided based on the TS output from the first channel selection unit, and after the channel switching operation, the broadcast channel after channel switching is selected. The switching operation is performed so as to provide the video service based on the output TS of the selected channel selection unit (in this example, the second channel selection unit). However, in the apparatus of Patent Document 1, there is not always a channel selection unit that selects a broadcast channel after channel switching, and the possibility of such a problem occurring with a probability that cannot be ignored cannot be eliminated.

  On the other hand, in the present embodiment in FIG. 2C, as described above, the video service is initially provided based on the TS output from the first channel selection unit. Corresponds to the broadcast channel after the switching among the TSs that have been temporarily stored in the temporary storage device 210 as the output of the second to nth channel selection units 102,..., (100 + n) until the time immediately before. The TS is selectively output from the output selection unit 500, and apparently, the broadcast service after switching can be provided promptly.

  In order to provide a regular (real-time) video service based on the output of the first channel selection unit 101 while the provision of the video service is continued without any apparent interruption by the data stored in the temporary storage device 210. Preparation operation (accumulation of required data) is continued, and after this preparation is completed, the regular video service is performed again based on the output of the first channel selection unit 101.

  As for data broadcasting, in a similar manner, data broadcasting information that is output from the first to n-th channel selection units 101,..., (100 + n) until the time immediately before the channel switching operation time is temporarily stored in the temporary storage device 210. Information corresponding to the broadcast channel after switching is output under the management of the temporary storage management unit 200, and apparently the data broadcasting service after switching can be provided promptly ( (Section marked “accumulation display” in the figure).

During the period in which the data stored in the temporary storage device 210 is being output, the preparation operation for outputting the data content related to the corresponding broadcast channel is continued, and when the preparation is completed, the data content is output.
As described above, according to the embodiment of the present invention, the data broadcast is also displayed immediately after channel switching, the blank period does not occur, and the number of broadcast channels scheduled to be selected Even if the configuration is so simple that the number of channel selection units is not enough, it is possible to realize a digital broadcast receiving apparatus capable of quickly displaying the corresponding content after channel switching.

It is a block diagram showing the structure of the digital broadcast receiver as embodiment of this invention. It is a figure for demonstrating the effect | action in embodiment of this invention in the comparison with a prior art example.
