Hereinafter, an embodiment of the present invention will be described by taking as an example an application to a broadcast receiver that is mounted on an automobile and receives a terrestrial digital TV broadcast.
FIG. 1 shows a configuration of a broadcast receiver according to the present embodiment.
As shown in the figure, the broadcast receiver includes an antenna 1, a front end unit (FE) 2, a demodulation unit 3, an MPEG decoder 4, a display device 5, an audio output device 6 including an amplifier and a speaker, a control unit 7, and a memory. 8 and a remote controller 9 having 12 number keys each assigned with a remote control number from 1 to 12.

  In such a configuration, the front end unit 2 receives a frequency channel designated as a reception channel from the control unit 7 and outputs a reception signal to the demodulation unit 3. The demodulator 3 performs demodulation / decoding processing such as OFDM demodulation and Viterbi decoding on the input received signal to restore MPEG2 TS (Transport Stream) and send it to the MPEG decoder 4. The MPEG decoder 4 decodes the organization channel (program) designated by the control unit 7 of the MPEG2 TS. Then, the decoded video signal is output to the display device 5, the decoded audio signal is output to the audio output device 6, and various decoded control information is output to the control unit 7.

Further, the demodulator 3 refers to the reception electric field strength of the front end unit 2 and the like, measures the reception quality of the received signal, and notifies the control unit 7 of the reception quality.
Next, the preset table stored in the memory 8 in the present embodiment will be described.
As shown in FIG. 2a, the preset table has 12 entries in which remote control numbers 1 to 12 are respectively registered, and an entry having a remote control number n includes the frequency channels that can be received at this time. The identifier of the broadcast station of the frequency channel whose Remote_Control_Key_ID is n (broadcast station name, NID: Network_identification, etc.) and the 3-digit channel number assigned to each organization channel included in the frequency channel are registered.

Here, the contents of this preset table are updated by a channel scan process executed by the control unit 7 at predetermined time intervals (for example, 10 minutes).
That is, in the channel scan process, the control unit 7 controls the front end unit 2 to search for a receivable frequency channel, and from each searched frequency channel, information on Remote_Control_Key_ID of the frequency channel, broadcast station, and organization channel information Receive. The information on the organization channel received here includes the service type of the organization channel (television / data broadcasting / partial reception: one segment) and the service number of the organization channel.

  Then, after clearing the contents of each entry in the preset table, for each searched frequency channel, in the preset table, the entry of the same value as the Remote_Control_Key_ID identified by the frequency channel, the broadcast station of the frequency channel, and the frequency Register the three-digit channel number assigned to the channel organization channel.

Further, at this time, the control unit 7 separately registers the frequency channel and other various information of the organization channel, which are necessary for accessing each organization channel assigned with the three-digit channel number, as organization channel access information in the memory. .
Here, the three-digit channel number of each organization channel is
Organization channel service type x 200 + Remote_Control_Key_ID x 10 + service number + 1
Assign by.

  In addition, when a plurality of frequency channels having the same value of Remote_Control_Key_ID can be received, a different branch number is added to the three-digit channel number of each organization channel in the channel scan processing for each frequency channel including each organization channel. . The branch numbers are given in the order of 0, 1, 2,... In order of good reception quality of the reception signal notified from the demodulator 3.

Next, the control unit 7 changes the branch number of the three-digit channel number of each organization channel in the channel preset process every time such a channel scan process performed every predetermined time interval is completed. Details of this channel preset processing will be described later.
Now, in such a configuration, the control unit 7 performs the following process if any one of the number keys 1 to 12 of the 12 keys of the remote controller 9 is operated.
In other words, if the operated number key is different from the remote control number of the preset table entry in which the three-digit channel number of the composition channel currently being received is registered, the remote control of the operated number key of the preset table is performed. Of the knitting channels with the last one digit of the three-digit channel number registered in the number entry, the knitting channel with a branch number of 0 is set as the reception target knitting channel. However, in this case, no branch number is treated as being equal to branch number 0.

  On the other hand, when the operated number key is equal to the remote control number of the entry in the preset table in which the three-digit channel number of the organization channel currently being received is registered, and a plurality of broadcasting stations are registered in the entry. Indicates that the last digit of the 3-digit channel number registered in the remote control number entry of the operated number key in the preset table is 1, and is next to the branch number of the 3-digit channel number of the organization channel currently being received. A composition channel having a three-digit channel number to which a large branch number is added is defined as a reception target composition channel. However, if the branch number of the three-digit channel number of the organization channel currently being received is the largest branch number, the three-digit channel number registered in the remote control number entry of the operated number key in the preset table Of the knitting channels whose last one digit is 1, the knitting channel whose branch number is 0 is set as the receiving knitting channel. In this case, no branch number is treated as being equal to branch number 0.

In addition, in response to the operation of the sub-channel selection key provided in addition to the 12 keys of the remote controller 9, the control unit 7 sets the knitting channel having the three-digit channel number whose lower one digit is not 1 as the receiving knitting channel. The processing to do is performed.
Then, the control unit 7 controls the front end unit 2, the demodulation unit 3, and the MPEG decoder 4 based on the organization channel access information of the reception target organization channel, and receives the frequency channel of the reception target organization channel and the reception target organization. Channel demodulation, decoding, and output to the display device 5 and the audio output device 6 are performed.

Next, the control unit 7 controls the reception of the organization channel in accordance with the user operation in this way, and the viewing time for each broadcast station series (program supply series / network) and for each broadcast station. Are managed in relation to the remote control number.
That is, the memory 8 is provided with a viewing time management table having a sequence entry that is an entry for each broadcast station sequence, as shown in FIG. Each series entry is provided with an entry for each remote control number assigned to the broadcasting station in the series of the series entry as a number entry. Each number entry is provided with an entry for each broadcasting station that is a broadcasting station in the sequence entry sequence including the number entry and to which the remote control number of the number entry is assigned as a broadcasting station entry.

  In the broadcast station entry, the period in which the broadcast channel of the broadcast entry of the broadcast entry is output in a state where the remote control number of the number entry including the broadcast station entry is assigned is registered as the viewing time for each broadcast station. In the number entry, the total viewing time for each broadcasting station registered in each broadcasting station entry included in the number entry is registered as the viewing time for each number. Also, in the series entry, the total viewing time for each number registered in each number entry included in the series entry is registered as a viewing time.

  That is, the control unit 7 sets a certain knitting channel as the reception target knitting channel and starts outputting the knitting channel. When the output of the knitting channel is finished, the control unit 7 starts counting time. In the viewing time management table, the viewing time by broadcasting station of the broadcasting station entry of the broadcasting station of the organization channel that was output, the viewing time by number of the number entry including the broadcasting station entry, and the broadcasting station This is added to the viewing time of the series entry including the entry.

The series to which each broadcast station belongs can be acquired from the frequency channel of the broadcast station as a BIT series ID. Alternatively, the correspondence between each broadcast station and the series may be registered in the memory 8 in advance.
Now, the above-described channel preset process will be described.
FIG. 3 shows the procedure of the channel preset process.
As shown in the figure, in this process, the control unit 7 monitors the end of the channel search process described above (step 302). If the end of the channel search process occurs, each remote control number (in the figure, “ The following processing is performed for the entry (abbreviated as “RCN”) (steps 304, 310, and 312).

That is, it is checked whether or not a branch number is added to the three-digit channel number of each organization channel registered in the entry of the remote control number (step 306). If not added, the processing for this entry is terminated. To do.
On the other hand, when a branch number is added to the 3-digit channel number, the viewing time of each broadcasting station registered in the entry of the remote control number is checked from the viewing time for each broadcasting station in the viewing time management table. The branch number of the three-digit channel number of the organization channel of each broadcasting station is changed so that the organization number of the broadcasting station with a longer time becomes smaller (step 308), and the processing for this entry is finished. .

When the processing for all the remote control number entries in the preset table is completed as described above, the process returns to step 302 and waits for the completion of the next channel search.
The embodiment of the present invention has been described above.
As described above, according to the present embodiment, when a plurality of broadcasts are assigned to the same remote control number, when the number key of the remote control number is operated, the remote control is used as a broadcast to be viewed by the user. Of the plurality of broadcasts assigned to the number, the broadcast of the broadcast station that the user most frequently views is selected as the broadcast that is used for viewing by the user. Here, since the broadcast of the broadcasting station that the user is watching most frequently has a high probability that the broadcast content matches the user's preference, according to this broadcast receiver, as a broadcast to be viewed by the user, A highly probable broadcast that matches the user's preference can be selected.

  Incidentally, step 308 of the channel preset processing in the above embodiment may be performed as follows. That is, the viewing time of the series to which each broadcasting station registered in the entry of the remote control number i in the preset table belongs is checked from the viewing time of each series entry in the viewing time management table, and the broadcasting station of the series having a larger viewing time is checked. You may make it change the branch number of the three-digit channel number of the organization channel of each broadcasting station so that an organization channel may become smaller branch number.

Here, since the broadcast contents of the same series of broadcast stations have high program identity, even in this way, a broadcast that matches the user's preference can be selected as a broadcast to be viewed by the user. .
Alternatively, step 308 of the channel preset process may be performed as follows. That is, for each series to which each broadcast station registered in the entry of the remote control number i in the preset table belongs, it is a broadcast station in that series, and the viewing time of the broadcast station to which the remote control number i is assigned. The total is obtained from the viewing time by number of the number entry of the remote control number i of the sequence entry of the sequence of the viewing time management table, and the broadcast channel organization channel of the broadcasting station of the sequence having the larger viewing time by number is obtained. The branch number of the three-digit channel number of the organization channel of each broadcasting station may be changed so that becomes smaller.

  In this way, a plurality of broadcasts assigned to different remote control numbers of the same series of broadcast stations while selecting a broadcast with a high probability that matches the user's preference as a broadcast to be viewed by the user. Can be received, it is possible to prevent the broadcasts of the same program providing series from being selected redundantly in response to the operation of the number key of each remote control number.

In the above embodiment, the channel preset process shown in FIG. 3 may be performed as follows.
That is, the control unit 7 manages the viewing time for each program type such as sports and movies using a viewing time management table as shown in FIG.
That is, the control unit 7 monitors the change of the program of the organization channel being output and the program type of each program during the output of the organization channel, and views the time when the program before the change was viewed each time the program changes. This is added to the viewing time of the program type entry of the program before the change in the time management table. Here, it is possible to identify the program type of the program being broadcast on each organization channel, the EPG information provided in the SI format or other format by the broadcast, and the like.
Then, the channel preset process is performed as follows.
That is, in this process, the control unit 7 monitors the end of the channel search process described above (step 402). If the end of the channel search process occurs, the control unit 7 (for each remote control number entry in the preset table ( Steps 404, 410, 412), the following processing is performed.

That is, it is checked whether a branch number is added to the 3-digit channel number of each organization channel registered in the entry of the remote control number (RCN) in the preset table (step 406). The process for this entry is terminated.
On the other hand, when a branch number is added to the three-digit channel number, for each broadcast station registered in the entry of the remote control number (RCN) in the preset table, the service number 0 of the broadcast station is organized. The program type of the program being broadcast on the channel is identified, and the viewing time of the program type identified from the viewing time management table is acquired. Then, the branch number of the three-digit channel number of the broadcast channel of each broadcast station is changed so that the branch number of the broadcast channel with the longer viewing time acquired becomes smaller (step 408). Terminate the process.

  When the processing for all the remote control number entries in the preset table is completed as described above, a timer having a predetermined timeout time (for example, 3 minutes) is set (step 414), and the channel search processing is performed. The occurrence of termination (step 416) and the occurrence of timer timeout (step 418) are monitored. If any of them occurs, the processing from step 404 is repeated.

  According to such channel preset processing, when a plurality of broadcasts are assigned to the same remote control number, when the number key of the remote control number is operated, the remote control number is used as a broadcast to be viewed by the user. Among the plurality of broadcasts assigned to the broadcast, the broadcast that is broadcasting the program of the program type that the user most frequently views is selected as the broadcast that the user views. Therefore, it is possible to select a broadcast having a high probability that matches the user's preference as a broadcast to be viewed by the user.

  Note that the viewing time managed in the viewing time management table shown in the above embodiment may be a broadcast viewing time within a certain past period.
