When an operation for selecting a program is performed, data that matches the service ID of the program at the latest broadcast time out of the data of the first data table. ,
It is checked whether it is in the second data table. If the check shows that there is a program, the program with the service ID is selected. The receiver is designed to select the program by repeating the same process for the service ID of the program having the next newer broadcast time. Therefore, by designating the program itself, the program is selected and received.

[0008]

FIG. 1 shows an example in which the present invention is applied to a DAB radio receiver. Then, in the receiving circuit 10, the DAB broadcast wave signal is received by the antenna 11, and the received signal is supplied to a tuner circuit 12 having from a synthesizer type front-end circuit to a demodulation circuit, and digital data is extracted. This digital data is a baseband signal,
In accordance with the B standard, digital audio signals of a plurality of channels and various data are multiplexed.

The digital data is supplied to a transmission path decoding circuit 13, where processing such as deinterleaving, error correction, and selection of target program data is performed. Circuit 14

The memory 24 contains, for example, FIG.
Are provided as shown in FIG.
In this case, the data table 31 shows the selection history of the service, and therefore has data columns of an ensemble ID, a service ID, a program type, and a broadcast date and time of a program selected in the past. The data table 32 indicates the frequency of program selection, and has a program type data column. Further, the data table 33 shows the currently selectable services,
It has data columns for ensemble ID, service ID, and program type.

Then, every time a program is selected, the data of the program and the date and time indicated by the clock circuit 25 are replaced with the oldest data in the data table 31, so that the data table 31 is updated. In addition, the data table 32 is rearranged in accordance with the frequency of the program according to the data of the selected program, and the data table 33 is also updated.

In such a configuration, when a predetermined key among the keys 21 is operated, a menu indicating a program selection mode is displayed on the LCD 23, as shown in FIG. A cursor 231 is displayed on the left side of the item. When the knob of the jog dial 22 is turned left and right, the cursor 231 moves up and down between the items.

In this example, as the program selection modes, (1) the latest history priority selection mode, (2) the program type frequency order selection mode, and (3) the same time zone service priority selection mode are prepared. In these selection modes, program selection is performed as follows.

(1) Selection mode with the latest history priority Turn the jog dial 22 to position the cursor 231 on the first item as shown in FIG. 4A, for example, and press the jog dial 22 as it is to display the first item. Enter the item "Selection mode with latest history priority".

In this selection mode, the data of the data table 31 is, for example, as shown in FIG. 3A, a set of data of an ensemble ID, a service ID, a program type, and a broadcast date and time, and according to the data of the broadcast date and time. , Sorted by newest.

Subsequently, of the data in the rearranged data table 31 (FIG. 3A), the service ID of the latest broadcast date and time, that is, the service ID in the first column
It is checked whether a service ID matching “YYYY” exists in the data table 33. Since there is no current case, of the data in the data table 31, the service ID of the second newest broadcast date and time, that is, the service ID that matches the service ID “XXXX” in the second column is in the data table 33. It is checked whether it is.

In this case, since the data is in the first column of the data table 33, the program is selected in accordance with the service ID, and thereafter the selected state of the program continues. At this time, information on the selection is displayed on the LCD 23 as shown in FIG. 4B, for example.

Further, at this time, when the jog dial 22 is turned, the next candidate is selected. That is, of the data in the data table 31, the service ID of the third latest broadcast date and time, that is, the service ID “XX” in the third column
It is checked whether a service ID matching "YY" exists in the data table 33. In this case, since the data is in the second column of the data table 33, the program is selected in accordance with the service ID, and thereafter, the selected state of the program continues. That is, the next candidate program is selected.

Thus, when the jog dial 22 is turned,
Subsequent candidate programs are similarly selected. When there is no candidate program, the program returns to the first selected program and is selected.

(2) Selection mode by frequency of program type Turn the jog dial 22 to move the cursor to the second item.
If the jog dial 22 is pressed as it is and the jog dial 22 is pressed as it is, the second item “selection mode by program type frequency order” is entered.

In this selection mode, the data table 32 (which is always rearranged in order of frequency)
, The program type of the program most frequently received, that is, the program type “XX” in the first column
XX "is the same as data table 3
3 is checked. In this case, since the data is in the first column of the data table 33, the program is selected in accordance with the service ID.
The selection state of the program continues.

Further, at this time, when the jog dial 22 is turned, the operation for selecting the next candidate is performed. That is, of the data in the data table 32, it is checked whether the program type of the program having the second reception frequency, in this case, the program type matching the program type "YYYY" in the second column exists in the data table 33. Is done. In this case, since the data is in the second column of the data table 33, the program is selected in accordance with the service ID, and thereafter, the selected state of the program continues. That is, the next candidate program is selected.

Thus, when the jog dial 22 is turned,
Subsequent candidate programs are similarly selected. When there is no candidate program, the program returns to the first selected program and is selected.

(3) Selection mode by priority of service in the same time zone Turn the jog dial 22 to move the cursor 2 to the third item.
If the jog dial 22 is pressed as it is while the position 31 is located, the third item “selection mode with priority on service in the same time zone” is entered.

In this selection mode, as shown in FIG. 3B, for example, as shown in FIG. 3B, the data of the data table 31 is a set of ensemble ID, service ID, program type, and broadcast date and time. Sorted in order.

That is, FIG. 3B shows a rearrangement result in the case where the current time is on the 10 o'clock on Wednesday. In this rearrangement, the current day of the week is given the highest priority and arranged in the order of the day. On the same day of the week, the current time zone is prioritized and arranged in time zone order. Also, at this time, if the time is the same, for example, 10:00 and 10:59 are treated as the same 10:00 unit, they are treated as the same time zone.

Subsequently, it is checked whether the data table 33 has a service ID that matches the service ID "XXXX" in the first column among the data of the rearranged data table 31 (FIG. 3B). You. In this case, since the data is in the first column of the data table 33, the program is selected in accordance with the service ID, and thereafter, the selected state of the program continues.

Further, at this time, turning the jog dial 22 selects the next candidate. That is, in the data of the data table 31, the service ID “YY
It is checked whether a service ID matching "YY" exists in the data table 33. In this case, since the data is not in the data table 33, it is checked whether or not the data in the data table 31 has a service ID that matches the service ID “XXYY” in the third column. In this case, since the service ID matches the service ID in the second column of the data table 33, the program is selected in accordance with the service ID, and the program selection state continues thereafter. That is, the next candidate program is selected.

Thus, when the operation of selecting the next candidate is performed,
Subsequent candidate programs are similarly selected. When there is no candidate program, the program returns to the first selected program and is selected.

As described above, in the receiver of FIG. 1, the program can be selected by the three types of selection modes (1) to (3).
Since the program itself is selected based on the past reception history, the target program can be easily selected.
In addition, since a learning function is provided, it is possible to select a program that suits the user's preference without performing complicated settings.

The routine 100 shown in FIG.
It is an example of a routine for realizing the “selection mode with latest history priority” in the section (1). That is, as shown in FIG. 4A, for example, when the jog dial 22 is pressed while the cursor 231 is in the selection mode of the item (1), the processing of the CPU of the microcomputer 20 is changed to the routine 100.
Starting from step 101 of step
, A pointer is set in the first column of the data column of the data table 31 (FIG. 3A).

Subsequently, in step 111, the service I at the position of the pointer set in step 102
A service ID matching D is searched from the data table 33.

Then, the search result is determined in step 112, and if there is a matching service ID, the process proceeds from step 112 to step 113,
In this step 113, the matched service I
The selection of the program D is executed, and then the routine 100 is ended in step 115.

If there is no matching service ID in step 112, the process proceeds from step 112 to step 121. In this step 121, the pointer set in the data table 31 is located at the bottom column of the data table 31. Is determined. If it is not located at the bottom column, the process proceeds from step 121 to step 122. In this step 122, the pointer is moved to the next column of the data table 31, in this case, the second column. ,
The process returns to step 111.

Therefore, after that, steps 111 to 122 are repeated until the service ID in the data column from the second column of the data table 31 onwards is obtained from the data table 33 until the service ID corresponding to the service ID is obtained from the data table 33. If there is a service ID, step 11
3, the program with the service ID is selected.

When the pointer is located at the bottom column of the data table 31 in step 121, the process proceeds from step 121 to step 115,
This routine 100 ends.

Thus, according to the routine 100, (1)
The item “selection mode with latest history priority” is realized.

The routine 200 shown in FIG. 6A is an example of a routine for realizing the "selection mode by priority of service in the same time zone" of the above item (3). That is, when the jog dial 22 is pressed while the cursor 231 is in the selection mode of the item (3), the processing of the CPU of the microcomputer 20 starts from the step 201 of the routine 200. The data in the table 31 is rearranged in chronological order by comparing the hours of the hour.

Subsequently, in step 203, the data table 31 rearranged in step 202
, The current time and day of the week are prioritized and rearranged. Then, thereafter, in step 204, the data table 31 of the result of step 203
And the data table 33 are used to execute the same processing as that of the routine 100 to select a channel.
Terminates the routine 200.

In this case, step 203 can be configured, for example, as a routine 300. That is, in the routine 300, the processing is performed in step 30.
1, the data of the current time and the day of the week are obtained from the clock circuit 25 in step 302, and subsequently, in step 303, the data table 3
1 (FIG. 3A), in the “hour” data column that is the same as the “hour” of the current time acquired in step 302,
The pointer is set.

Next, in step 304, of the data in the data table 31, from the first column to step 30
The data located up to the data column before the pointer set by 3 is moved to the end of the data table 31. Then, in step 305, the data of the data table 31 processed in step 304 are rearranged in the order of the day of the week so that the current day of the week acquired in step 302 comes before the data having the same "hour". After that, the routine 300 ends in step 306.

Thus, according to the routines 200 and 300, the "selection mode by priority of service in the same time zone" of the item (3) is realized.
