Description

  The present invention relates to a broadcast receiver, a broadcast reception method, a broadcast reception program, and a recording medium.

  Broadcast receivers can be selected by assigning physical channels (frequency) to the remote control or numeric keys on the broadcast receiver, or displaying a list of receivable stations on the screen so that users can easily select broadcast station programs to watch. It has a means for registering receivable channel information such as making it possible.

In addition, in digital terrestrial television broadcasting started using the terrestrial UHF (Ultra High Frequency) band in the three large areas of Kanto, Kinki, and Chukyo from December 1, 2003, the numeric keys on the remote control A default number (remote_control_key_id, abbreviated as remote control key ID) for allocation is included in a broadcast wave transmitted from each broadcast station and transmitted, and the remote control key ID instead of the physical channel number becomes a channel number known to the user. ing.
Therefore, it is necessary to hold receivable channel information in the broadcast receiver, and to associate the broadcast station or remote control key ID with the physical channel number (frequency).

As a method for creating receivable channel information, for example, a method for holding receivable channel information in units of regions in a broadcast receiver in advance and using receivable channel information of a region set by a user when the broadcast receiver is installed is used. There is a method of creating receivable channel information by confirming whether or not each physical channel (frequency) can be received by channel scanning.
When a broadcast station is selected by a user key operation or the like, the broadcast receiver selects a physical channel that can receive the selected broadcast station based on receivable channel information.

On the other hand, there are two types of schemes (retransmission schemes) that once receive and transmit broadcast waves at a relay station in the service area. One is an SFN (Single Frequency Network) system, which performs retransmission at the same frequency. The other is an MFN (Multi Frequency Network) system, which performs retransmission at different frequencies.
When channel scanning is performed in an area where the MFN system is operated, the same broadcast station may be found on a plurality of physical channels (frequencies).

  In the receivable channel information when broadcasts of the same broadcasting station can be received by a plurality of physical channels, one physical channel (frequency) is allocated to one broadcasting station in the fixed receiver. For example, when broadcasts from the same broadcasting station can be received by a plurality of physical channels by channel scanning, one physical channel having an excellent C / N or error rate is selected and stored in the receivable channel information (for example, Patent Documents). 1).

  In a fixed receiver, one pattern of receivable channel information may be set when the receiver is installed. However, when a broadcast is received while moving, the physical channel corresponding to the broadcast station that can be received changes according to the position. Therefore, a plurality of preset information is provided for each place, and appropriate receivable channel information is reset at the destination (for example, see Patent Document 2).

In addition, it is intended to group a plurality of related services by a bouquet and to identify the relations concisely (for example, refer to Patent Document 3), and to eliminate inconvenience and dissatisfaction in channel setting. (For example, see Patent Document 4) has been developed.

[Configuration of Example]
FIG. 1 is a block diagram showing an embodiment of a broadcast receiver according to the present invention.
The broadcast receiver 10 shown in the figure includes an antenna 11, a broadcast receiving unit 12, a key input unit 13, a control unit 14, a display unit 15, a voice presentation unit 16, and a receivable channel information holding unit 17. Consists of.

The antenna 11 receives a broadcast wave, and the received broadcast wave signal is input to the broadcast receiving unit 12.
Examples of the antenna 11 include a Yagi-Uda antenna (including a stack antenna), a rod antenna, and a loop antenna in the case of the UHF band.
The broadcast receiving unit 12 receives and demodulates a signal having a frequency corresponding to the channel designated by the control unit 14.
The control unit 14 performs overall control processing in the broadcast receiver 10 such as reception control, decoding of received data (video, audio, etc.) and display control.
The reception data output from the broadcast receiving unit 12 is decoded by the control unit 14 into video, audio, etc., displayed on the display unit 15, and presented to the audio presentation unit 16.
The key input unit 13 is a part that receives instructions regarding broadcast reception from the user such as channel setting, and the input information is input to the control unit 14 and used for reception control and display control.
The receivable channel information holding unit 17 is a part that holds receivable channel information used at the time of channel selection.

[Description of Operation of Example]
FIG. 2 is a flowchart showing an example of a general channel scan operation.
The range and order of physical channels (CH) to be confirmed for reception are determined (set) (step S1).
First, channel selection is performed for the physical channel to be confirmed for reception, and whether or not reception is possible is confirmed (step S2).
Information on the presence / absence of broadcast waves is stored (step S3).
It is determined whether there is a broadcast wave (step S4).
When the broadcast wave cannot be received (step S4 / no), the process proceeds to reception confirmation of the next physical channel. That is, it is determined whether there is a CH to be received next (step S6).
When the broadcast wave can be received (step S4 / yes), necessary information is acquired from the broadcast wave (step S5), and the process proceeds to reception confirmation of the next physical channel (step S6).
If there is a next CH to be received (step S6 / yes), the next CH to be received is set. This is performed for all physical channels for which reception is confirmed (step S7).
Next, when there is no CH to be received (step S6 / no), the process is terminated.

Table 1 is an example of scan results in a broadcast receiver that receives terrestrial digital television broadcasts, and lists physical channels that could be received at the time of scanning.

  In the table, the broadcast station name, network_id, remote_control_key_id, and transmission physical channel are information acquired from the broadcast wave at the time of scanning. One network_id is assigned to one transmission master in digital terrestrial television broadcasting, and corresponds to the ID of the broadcasting station. The transmission physical channel is obtained by converting the transmission frequency described in the terrestrial distribution system descriptor in the broadcast wave into a physical channel. In the transmission frequency field, a plurality of frequencies are described when the MFN method is used.

  Using the channel scan result thus obtained, in the present invention, receivable channel information is created by associating a plurality of physical channels that transmit the same broadcast to each broadcast station.

Table 2 shows an example of receivable channel information in the present invention created from the scan results of Table 1.

In the case of digital terrestrial television broadcasting, it can be determined from the network_id included in the broadcast wave whether the broadcast station of the received broadcast wave is the same broadcast station. In this example, since the physical channels 15 and 25 are the same network_id, it is determined that they are the same broadcast, and the physical channels 15 and 25 are stored in the physical channel list for the broadcast station A in the receivable channel information.
Furthermore, in the example of Table 2, not only the physical channels that can be received by scanning, but also the transmission frequencies described in the terrestrial distribution system descriptor are stored in the physical channel list.

  Using the receivable channel information created in this way, the channel selection operation of the designated broadcast station is performed.

FIG. 3 is a flowchart showing an example of a channel selection flow of the broadcast receiver according to the present invention.
In FIG. 3, first, a user designates (selects) a broadcast station to be viewed by means such as operating keys on a remote controller or a broadcast receiver (step S11).
Next, the broadcast receiver refers to the physical channel list of the broadcast station designated from the receivable channel information, and selects the first physical channel in the physical channel list (step S12).
Here, it is determined whether or not there is a broadcast wave that can be viewed (step S13), and it is determined whether or not it is a broadcast wave of the selected broadcast station (step S14). A viewable broadcast wave can be received (step S13 / yes), and if it is a broadcast wave of a designated broadcast station (step S14 / yes), the received physical CH is moved to the head of the physical CH list (step S15). Watch on the physical channel as it is.

When there is no broadcast that can be viewed because the broadcast wave cannot be received, or the playback quality that can be viewed cannot be obtained even if it can be received (step S13 / no), or the broadcast station that the received broadcast has designated When the broadcast is different (step S14 / no), the next physical channel in the physical channel list is selected. This is repeated until a broadcast of the designated broadcasting station is found (step S16, step S17).
When a broadcast of the designated broadcast station that can be viewed is found (step S13 / yes, step S14 / yes), the physical channel selected at that time is moved to the head of the physical channel list (step S15).

  In this way, when the user next selects the broadcast station at the same location, the target physical channel is at the head of the physical channel list. Also, a physical channel that is frequently selected, that is, a physical channel at a frequently visited place comes to the front of the physical channel list. For this reason, it is possible to shorten the time required for selecting a channel in the physical channel list in order and viewing the broadcast of the designated broadcast station.

Next, another embodiment of the broadcast receiving apparatus according to the present invention will be described.
The order of physical channels stored in the physical channel list may be determined in any way. The order may be random, or may be determined according to the reception status of each physical channel at the time of scanning. For example, it may be possible to store the physical channel list in order from the one with the good reception status at the time of scanning.

  In the example of FIG. 3, the physical channel that was actually viewable has been moved to the top of the physical channel list, but the reception status when it was received can be stored together and the physical channel can be received in the past. The order of the physical channel list may be determined based on the order of physical channels having the best maximum value, average value, etc., or the order of physical channels having a large number of receptions.

  The operation when the target broadcast that can be viewed is found is a flow in which the found physical channel is continuously received in the example of FIG. 3, but the physical channel in the physical channel list is received again when the reception situation deteriorates. It is also possible to check the alternative physical channel.

  The operation when the viewable broadcast station is not found even after making a round of the physical channel list is a flow of returning to the head of the physical channel list until the viewable broadcast station is found in the example of FIG. However, as shown in FIG. 4, it is possible to change the operation of the second round and wait until reception is possible on the first channel in the physical channel list.

FIG. 4 is a flowchart showing another example of the channel selection flow of the broadcast receiver according to the present invention.
In FIG. 4, first, the user designates (selects) a broadcast station to view by means such as operating keys on a remote controller or a broadcast receiver (step S21).
Next, the broadcast receiver refers to the physical channel list of the broadcast station designated from the receivable channel information, and selects the first physical channel in the physical channel list (step S22).
Here, it is determined whether there is a broadcast wave that can be viewed (step S23), and it is determined whether it is a broadcast wave of the selected broadcast station (step S24). A viewable broadcast wave can be received (step S23 / yes), and if it is a broadcast wave of a designated broadcast station (step S24 / yes), the received physical CH is moved to the top of the physical CH list (step S25). Watch on the physical channel as it is.

When there is no broadcast that can be viewed because the broadcast wave cannot be received, or the playback quality that can be viewed cannot be obtained even if it can be received (step S23 / no), or the broadcast station that is specified by the received broadcast When the broadcast is different (step S24 / no), it is determined whether or not the entire physical channel list has been confirmed (step S26).
When it is determined that all the physical CH lists have been confirmed (step S26 / yes), the top physical CH list of the corresponding broadcast station is selected (step S27) and waits until a broadcast wave that can be viewed is found (step S28). ), It is determined whether the selected broadcast station is a broadcast wave (step S29). If it is a broadcast wave of the selected broadcast station (step S29 / yes), the received physical CH is moved to the top of the physical CH list (step S25), and viewing is performed with the physical channel as it is.
When it is determined that the entire physical CH list has not been confirmed (step S26 / no), the next physical CH is selected (step S30), and the process returns to step S23.
If it is not the broadcast wave of the selected broadcast station (step S29 / no), the next physical CH is selected (step S31), and the process returns to step S28.
Even in this case, the same effect as described above can be obtained.

  In addition, the flow is not the flow of continuously receiving the physical channel in which the specified broadcast station is found as shown in FIG. 3, but the reception confirmation is possible for all the physical channels in the physical channel list as shown in FIG. In addition, the flow may be such that the physical channel with the best reception status among the physical channels of the designated broadcast station is the reproduction physical channel.

FIG. 5 is a flowchart showing still another example of the channel selection flow of the broadcast receiver according to the present invention.
A broadcast station to be viewed is designated (selected) (step S51).
Next, the broadcast receiver refers to the physical channel list of the broadcast station designated from the receivable channel information, and selects the first physical channel in the physical channel list (step S52).
Here, it is determined whether there is a broadcast wave that can be viewed (step S53), and it is determined whether it is a broadcast wave of the selected broadcast station (step S54).
A broadcast wave that can be viewed can be received (step S53 / yes), and if it is a broadcast wave of a designated broadcast station (step S54 / yes), the reception status is saved (step S55), and whether or not all physical CH lists have been confirmed. If it is determined that all physical CH lists have been confirmed (step S56 / yes), the physical CH with the best reception status is selected (step 57) and viewed as it is.
If it is determined that the entire physical CH list has not been confirmed (step S56 / no), the next physical CH is selected (step S58), and the process returns to step S53.

  Even in this case, the same effect as described above can be obtained.

  As the storage format of the receivable channel information, the physical channel number is stored in the physical channel list in the example of Table 2, but the frequency may be stored. In the case of terrestrial digital audio broadcasting, frequency information corresponding to a physical channel number is a physical channel number and a segment number, or a physical channel number and a subchannel number.

  In the example shown in Table 2, the transmission physical channel number of the broadcasting station is stored in association with one broadcasting station, but the ID of the affiliated station is further associated with the target broadcast at the time of channel selection. If the station broadcast cannot be received even after going around the physical channel list, or if it is out of the service area of the target broadcast station with reference to location information such as GPS or mobile phone base station information, etc. You may make it move to the reception confirmation of the physical channel list. A plurality of network_ids may be assigned to one broadcasting station, or a plurality of broadcasting stations may be assigned to one remote control number.

As shown in Tables 3 and 4, the relationship between the physical channel of the broadcasting station A and the physical channel of the broadcasting station B at a certain position may be acquired and used when selecting a channel.

  For example, the broadcast station A receives the physical channel list, and when the reception confirmation of 15Ch is received, the broadcast station B can receive, and when the broadcast station A can receive at 18Ch, the channel (15Ch) that can receive the broadcast station B is The channel (18Ch) in which the broadcast station A can be received is associated as the same reception pattern, and when the selection of the broadcast station A is specified while the broadcast station B is being received at 15Ch, the reception confirmation of 18Ch is given priority. Can be considered.

  The method of creating receivable channel information has been exemplified by channel scanning, but without performing channel scanning, receivable channel information for each region is held in advance in the receiver, such as GPS (Global Positioning System) The position information may be used for setting or according to the user's regional setting. Further, the information held in advance may be updated using the scan result or the reception result at the time of channel selection, or may be updated by the user.

  A plurality of broadcast receiving units may be installed. For example, while viewing on a certain physical channel, another broadcast receiving unit confirms reception in the physical channel list, and if a physical channel with better reception status appears, a method of switching to that channel can be considered.

  The example of using the network_id is given as the method for determining the same broadcast. However, the determination may be made by looking at the similarity between broadcast waves.

  The present invention can be used for a broadcast receiver, digital broadcast, analog broadcast, television, and radio that are used while moving.
