[Reception History Recording Method for Restricting Items Left in Reception History List: FIGS. 3 to 6] In the above-described receiver 1,
When a program is received, the reception history is stored in the reception history memory 31.
Is recorded in the reception history list,
You can select the program you want to listen to.

However, in order to make the receiver 1 compact and lightweight, the reception history memory 31 is of a relatively small capacity capable of recording reception histories for 10 to 20 programs. Is full, the old history is erased and a new history is recorded.

Therefore, every time a program is received, its reception history is recorded in the reception history memory 31. If the user switches programs one after another in a short time in order to search for a program he wants to listen to, the user will Programs that were not intended to be listened to were added to the receiving history list one after another, and when the user later tried to receive a previously listened program again, the program disappeared from the list. Therefore, there is a high possibility that a previously listened program cannot be searched.

Therefore, in each of the following examples, the programs for recording the reception history are limited to those satisfying predetermined conditions.

(First Example: FIG. 3) In the first example, the program for recording the reception history is limited to the programs continuously received for a predetermined time or more.

FIG. 3 shows an example of a reception history recording processing routine performed by the CPU 21 in this case. In the reception history recording processing routine 61, when starting reception of a program, the CPU 21 firstly starts the reception timer 33 in step 65, and then determines in step 66 whether the received program has been changed.

When the received program is changed,
Proceeding from step 66 to step 67, it is determined whether or not the time Tr measured by the reception timer 33 and continuously receiving the same program up to that time is longer than a predetermined threshold time Tth. , Tr ≦ Tth, that is, when the time Tr for continuously receiving the same program up to that time is equal to or less than the threshold time Tth,
Do not record the programs received until then as reception history,
Returning from step 67 to step 65, the reception timer 33 is started again.

On the other hand, when Tr> Tth, that is, the time T during which the same program was continuously received until then,
If r is longer than the threshold time Tth, step 67
Then, the process proceeds to step 69, where the program received so far is recorded as the reception history in the reception history memory 31, and then the process returns to step 65 to start the reception timer 33.

The threshold time Tth is set to, for example, 30 seconds. Therefore, when the user switches the received program in a short time such as several seconds or ten and several seconds to search for a desired program, the program is not recorded as a reception history, and the same program continues for more than 30 seconds. Only when the program is received, the program is stored in the reception history memory 31 as a reception history.
Will be recorded.

When the power of the receiver 1 is turned off,
As in the case where the received program is changed, the CPU 21 determines whether or not Tr> Tth in step 67, and when Tr ≦ Tth, the program received so far is not recorded as a reception history. When the reception history recording process is completed and Tr> Tth, the routine proceeds to step 69, where the programs received so far are recorded as the reception history in the reception history memory 31, and then the reception history recording process is ended.

As the reception history of the program, specifically, the component name and the component I
Record D (identifier) or program type.

According to this example, when a user switches programs one after another in a short time in order to search for a program to listen to,
The programs that the user did not intend to listen to are not added to the reception history list, and only the programs that the user intended to listen to and that have been continuously received for a predetermined time or more are added to the reception history list. The list significantly increases the probability that a previously listened program can be searched and received again.

(Second Example--FIG. 4) In the second example, the program for recording the reception history is limited to the program of the program type (program type) specified in advance by the user.

In the receiver 1, for example, FIG.
As shown in (B), various program types such as “ROCKMUSIC” are set, and the user displays a list of the program types on the LCD 39 and records one or more of them in the reception history. Can be specified as a program type.

FIG. 4 shows an example of a reception history recording processing routine performed by the CPU 21 in this case. In the reception history recording processing routine 62, when starting reception of a program, the CPU 21 first determines in step 66 whether or not the received program has been changed. When the received program has been changed, the process proceeds from step 66 to step 68a. It is determined whether the program before the change is a program of the specified program type.

If the program before the change is not a program of the designated program type, the program before the change is not recorded as the reception history, and the routine returns from step 68a to step 66, where the program before the change is designated as the designated program type. If the program is a type program, the process proceeds from step 68a to step 69, where the program before the change is recorded in the reception history memory 31 as the reception history, and then the process returns to step 66.

According to this example, since only the program of the program type designated by the user in advance is added to the reception history list, as in the first example of FIG. The probability of retrieving a program that has been heard and re-received is significantly increased.

(Third Example: FIG. 5) In the third example, a program for which a reception history is to be recorded has a program type (program type) designated by the user in advance and has been continuously received for a predetermined time or more. Restrict to

FIG. 5 shows an example of a reception history recording processing routine performed by the CPU 21 in this case. This reception history recording processing routine 63 is executed until the determination in step 67 is completed.
Is the same as the first example.

At step 67, if Tr ≦ Tth,
That is, when it is determined that the time Tr during which the same program has been continuously received up to that time is equal to or less than the threshold time Tth, the program received so far is set as a reception history, as in the first example of FIG. The process returns from step 67 to step 65 without recording.

On the other hand, at step 67, Tr> T
th, that is, when it is determined that the time Tr for continuously receiving the same program up to that time is longer than the threshold time Tth, the process proceeds from step 67 to step 68a, and the program received so far is designated as the designated program. It is determined whether or not the program is a program of the specified program type. The rest is the same as the second example in FIG.

(Fourth Example: FIG. 6) In the fourth example, the program for recording the reception history is limited to the program that the user instructed to record while receiving the program.

When the user intends to record the reception history of the program for later retrieval during the reception of the program, the user instructs to that effect by operating the operation unit 35.

FIG. 6 shows an example of a reception history recording processing routine performed by the CPU 21 in this case. In this reception history recording processing routine 64, instead of step 68a in the reception history recording processing routine 62 of the second example of FIG.
In step 68b, it is determined whether or not the user has performed a recording operation during the reception of the program before the change. If the recording operation has not been performed, the program before the change is not recorded as the reception history. Returning to step 66, when a recording operation is performed, the process proceeds from step 68b to step 69, where the program before the change is recorded in the reception history memory 31 as the reception history, and then the step 6 is performed.
Return to 6.

[Receiving history recording / reproducing method for facilitating program selection: FIGS. 7 to 16] In the present invention, a program received by a user in the past by using a past receiving frequency for a program ID or a program type is used. To easily and quickly select and receive a desired program. The specific method will be described below.

The following reception history recording / reproducing method can be used together with the reception history recording method shown in FIGS. 3 to 6, but it is also possible to perform only the following reception history recording / reproduction method without using the same. Good. When used together, the reception history recording processing in each of the following examples is performed as the processing of step 69 in the reception history recording processing routines 61 to 64 in FIGS.

(First Example: FIGS. 7 to 9) In the DAB, a component name and a component ID are added to each service component, and when the component name is selected by the user in the receiver 1, the component The component is searched by the component ID corresponding to the name, and is selectively received. However, the component ID is the same, and the component name may be changed.

Therefore, in the first example, the reception history is recorded by a method as shown in FIG. That is, in the reception history recording process 71 of FIG. 7, it is first determined in step 72 whether or not the component ID of the received program is recorded in the reception history memory 31. If not, the process proceeds from step 72 to step 74a. To the component name and component ID of the received program
Is recorded in the reception history memory 31 as frequency 1.

FIG. 9A shows a component name and a component ID for three programs.
Indicate the states recorded in the reception history memory 31 as the frequency 1 respectively.

If the component ID of the received program is recorded in the reception history memory 31, step 7
The process proceeds from step 2 to step 73 to determine whether or not the component name of the received program is the same as that recorded in the reception history memory 31. If not, the process proceeds from step 73 to step 74b and the reception history memory The component name recorded in 31 is rewritten to the component name of the received program, and the frequency is incremented by one.

In the state of FIG. 9A, as shown in FIG. 9B, the component ID is the same as that recorded in the reception history memory 31, and the component name is recorded in the reception history memory 31. When a program different from the received program is received, the component name recorded in the reception history memory 31 is rewritten to the component name of the received program, as shown in FIG. The frequency is increased by one.

When the component name of the received program is the same as that recorded in the reception history memory 31, the process proceeds from step 73 to step 74c, where the same component name as the received program recorded in the reception history memory 31 is stored. Add 1 to the frequency of the name and component ID.

When a program is selected, a reception history list is displayed on the LCD 39 by a method as shown in FIG. That is, in the reception history reproduction processing 75 of FIG. 8, first, in step 76, the reception history data (component name, component ID, and frequency) is read from the reception history memory 31, and then, in step 77, the reception history data is
Sorted in descending order of frequency, then step 78
Then, the reception history data after sorting (component name)
Is displayed on the LCD 39.

Therefore, when the program is selected and the reception history recorded in the reception history memory 31 is as shown in FIG. 9C, the component is displayed on the display screen 39a as shown in FIG. 9D. The first name is displayed. That is, a program (component name) with a component ID having a higher reception frequency in the past is displayed at the top of the display screen 39a. Those having the same reception frequency are displayed, for example, in descending history.

Therefore, the user does not need to scroll the display screen 39a greatly when finding a program received in the past, and can easily and quickly select and receive a desired program from programs received in the past. Can be.

(Second Example: FIG. 10 and FIG. 11) In the second example, at the time of recording the reception history, the component name and the component ID of the received program are not attached to the reception history memory 31 without frequency. To record.

For example, while the reception history (component name and component ID) is recorded as shown in FIG. 11A, the component ID is recorded in the reception history memory 31 as shown in FIG. Even when a program having the same component name and a different component name from that recorded in the reception history memory 31 is received, as shown in FIG. Is added to the reception history and recorded.

When a program is selected, a reception history list is displayed on the LCD 39 by a method as shown in FIG.
That is, in the reception history reproduction processing 85 of FIG. 10, first, at step 86, the reception history data (component name and component ID) is read from the reception history memory 31, and then, at step 87, the component ID is If the component names are the same but have different component names, the component names are rewritten to the latest ones, and the frequency is calculated for each component ID. , Then step 8
In step 9, the rearranged reception history data (component name) is displayed on the LCD 39.

Therefore, when the program is selected and the reception history recorded in the reception history memory 31 is as shown in FIG. 11C, the component is displayed on the display screen 39a as shown in FIG. The first name is displayed. That is,
A program (component name) with a component ID having a higher reception frequency in the past is displayed at the top of the display screen 39a. Those having the same reception frequency are displayed, for example, in descending history.

Therefore, as in the first example, when searching for a program received in the past, the user is required to display the display screen 39.
It is not necessary to scroll a a large amount, and it is possible to easily and quickly select and receive a desired program from programs received in the past.

(Third Example: FIGS. 12 to 14) The third example is a case where a program is selected according to a program type. In this case, various program types are prepared in advance in the reception history memory 31, and when the receiver 1 is shipped,
Alternatively, when the frequency is preset by the preset button 44, the frequency for each program type is set to zero.

In this example, the reception history is recorded by a method as shown in FIG. That is, in the reception history recording process 91 of FIG. 12, in step 92, the frequency of the program type of the received program is increased by one.

Therefore, in the state where the frequency for each program type is recorded as shown in FIG.
If the program type is "R ..." (for example, "ROCK
MUSIC "), the frequency of the program type is increased by one, as shown in FIG.

When a program is selected, a reception history list is displayed on the LCD 39 by a method as shown in FIG.
That is, in the reception history reproducing process 95 of FIG. 13, first, at step 96, the reception history data (program type and frequency) is read from the reception history memory 31, and then, at step 97, the reception history data is converted to the one with the higher frequency. The program types after the sorting are displayed on the LCD 39 at step 98.

Therefore, when the program is selected and the reception history recorded in the reception history memory 31 is as shown in FIG. 14B, the program is displayed on the display screen 39a as shown in FIG. The type is displayed. That is,
A program type having a higher receiving frequency in the past is displayed at the top of the display screen 39a. Those having the same reception frequency are displayed, for example, in the order of a preset number.

Therefore, the user does not need to scroll the display screen 39a greatly when finding the program type received in the past, and can easily and quickly select and receive the program of the program type received in the past. .

(Each search mode and reception history list: FIG. 1)
