If the result of the check is not, a receiver that selects the broadcast program by repeating the same process for the service ID of the broadcast program with the next newest selection date / time in the data of the first data table. It is what.
Therefore, by designating the program itself, the program is selected and received.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an example in which the present invention is applied to a DAB radio receiver. In the receiving circuit 10, a DAB broadcast wave signal is received by the antenna 11, and the received signal is supplied to a tuner circuit 12 including a synthesizer type front-end circuit to a demodulating circuit to extract digital data. This digital data is a baseband signal in which digital audio signals of a plurality of channels and various types of data are multiplexed according to the DAB standard.
[0009]
Then, this digital data is supplied to the transmission path decoding circuit 13 to execute processing such as deinterleaving, error correction, and selection of the data of the target program, and the processing result data is sent to the audio decoding circuit 14. Data is decompressed to the original digital audio signal supplied. Then, this digital audio signal is D / A converted into the left and right channel analog audio signals supplied to the D / A converter 15, and these audio signals are supplied to the speakers 17L and 17R through the amplifiers 16L and 16R. Is done.
[0010]
A microcomputer 20 is provided for system control. The microcomputer 20 selects the tuner circuit 12, selects the data of the target program in the decoding circuit 13, and the volume of the audio signal through the amplifiers 16L and 16R. Further, processing such as adjustment of sound quality is executed, and a PAD signal indicating supplementary information of program contents is supplied from the decoding circuit 14 to the microcomputer 20.
[0011]
Furthermore, the microcomputer 20 is provided with routines 100 to 300 shown in FIGS. 5 and 6, for example. The processing contents of the routines 100 to 300 will be described later. These are for selecting and receiving a program when the program is designated.
[0012]
Further, the microcomputer 20 is connected with an operation key 21 and a jog dial 22 for performing various input operations, and an LCD 23 is connected as a display element for displaying information on a received broadcast station, a program, and the like. .
[0013]
Further, the microcomputer 20 is connected to a memory 24 and a clock circuit 25 that measures the current time. In this case, the memory 24 is a ROM capable of electrically writing data, or a RAM backed up by a battery (not shown), that is, the memory 24 is a non-volatile memory. Even when the power is turned off, the written data can be held.
[0014]
The memory 24 is provided with data tables 31 to 33 as shown in FIG. In this case, the data table 31 shows a service selection history. Therefore, the data table 31 includes a data column for an ensemble ID, a service ID, a program type, and a broadcast date and time for a program selected in the past. The data table 32 shows the frequency of program selection and has a program type data column. Furthermore, the data table 33 shows services that can be currently selected, and has data columns for an ensemble ID, a service ID, and a program type.
[0015]
Each time a program is selected, the data of the program and the date and time data indicated by the clock circuit 25 are replaced with the oldest data in the data table 31, and therefore the data table 31 is updated. Further, the data table 32 is rearranged in the order of the frequency of the program according to the data of the selected program, and the data table 33 is also updated.
[0016]
In such a configuration, when a predetermined one of the keys 21 is operated, for example, as shown in FIG. 4A, a menu indicating a program selection mode is displayed on the LCD 23, and the left side of the first item among them is displayed. A cursor 231 is displayed on the screen. When the knob of the jog dial 22 is turned left and right, the cursor 231 moves up and down between the items.
[0017]
In this example, as the program selection mode,
(1) Selection mode with priority on latest history
(2) Selection mode by frequency of program type
(3) This is a case where a selection mode based on time zone / day of the week is prepared. In these selection modes, program selection is performed as follows.
[0018]
(1) Selection Mode with Latest History Priority Turn the jog dial 22 to position the cursor 231 at the first item and press the jog dial 22 as it is, for example, as shown in FIG. 4A. Enter "Selection mode with priority to latest history".
[0019]
In this selection mode, as shown in FIG. 3A, for example, the data in the data table 31 is a set of ensemble ID, service ID, program type, and broadcast date / time data. Rearranged.
[0020]
Subsequently, among the data in the rearranged data table 31 (FIG. 3A), the service ID corresponding to the latest broadcast date and time, that is, the service ID “YYYY” in the first column, is the data table 33. Is checked to see if Since there is no present case, in the data table 31, the service ID corresponding to the service ID “XXXX” in the second column among the data in the data table 31 is the data table 33. Is checked.
[0021]
In this case, since it is in the first column of the data table 33, the program is selected according to this service ID, and the selected state of the program continues thereafter. At this time, for example, as shown in FIG. 4B, information related to the selection is displayed on the LCD 23.
[0022]
At this time, if the jog dial 22 is turned, the next candidate is selected. That is, it is checked whether or not the data table 33 has a service ID that matches the service ID of the third newest broadcast date / time, that is, the service ID “XXYY” in the third column. In this case, since it is in the second column of the data table 33, the program is selected according to this service ID, and the selected state of the program continues thereafter. That is, the next candidate program is selected.
[0023]
Thus, when the jog dial 22 is turned, the subsequent candidate programs are selected in the same manner. When there is no candidate program, the program is selected after returning to the first selected program.
[0024]
(2) Selection mode by program type frequency order Turn the jog dial 22 to position the cursor 231 on the second item, and press the jog dial 22 as it is, then the second item “Select by Program Type Frequency Order” Enter "mode".
[0025]
In this selection mode, among the data in the data table 32 (which is always rearranged in order of frequency), the program type of the program having the highest reception frequency, that is, the program type “XXXX” in the first column It is checked whether there is a matching program type in the data table 33. In this case, since it is in the first column of the data table 33, the program is selected according to this service ID, and the selected state of the program continues thereafter.
[0026]
Further, when the jog dial 22 is turned at this time, an operation for selecting the next candidate is performed. That is, it is checked whether or not the data table 33 has a program type corresponding to the program type of the second reception frequency program in the data table 32, and in this case, the program type “YYYY” in the second column. Is done. In this case, since it is in the second column of the data table 33, the program is selected according to this service ID, and the selected state of the program continues thereafter. That is, the next candidate program is selected.
[0027]
Thus, when the jog dial 22 is turned, the subsequent candidate programs are selected in the same manner. When there is no candidate program, the program is selected after returning to the first selected program.
[0028]
(3) time zone / day of the week selection mode by turning the jog dial 22 to position the cursor 231 to No. 3 of item by, as it is, and press the jog dial 22, the selected mode by the "time of day / day of the third item "to go into.
[0029]
In this selection mode, as shown in FIG. 3B, for example, the data of the data table 31 is a set of ensemble ID, service ID, program type, and broadcast date and time, and is arranged in a predetermined order according to the broadcast date and time. Be replaced.
[0030]
That is, FIG. 3B shows the rearrangement result when the current day of the week and the time are in the 10 o'clock range on Wednesday. This rearrangement is arranged so that the current day of the week is the highest priority and the day of the week is in order. On the day of the week, the current time zone is arranged in time zone order with the highest priority. At this time, for example, 10:00 and 10:59 are treated as the same 10 o'clock range, and if the "hour" is the same, they are treated as the same time zone.
[0031]
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 in the rearranged data table 31 (FIG. 3B). In this case, since it is in the first column of the data table 33, the program is selected according to this service ID, and the selected state of the program continues thereafter.
[0032]
At this time, if the jog dial 22 is turned, the next candidate is selected. That is, it is checked whether the data table 33 has a service ID that matches the service ID “YYYY” in the second column among the data in the data table 31. In this case, since it is not in the data table 33, it is checked whether the data table 33 has a service ID that matches the service ID “XXYY” in the third column among the data in the data table 31. In this case, since it matches the service ID in the second column of the data table 33, the program is selected according to the service ID, and the selected state of the program continues thereafter. That is, the next candidate program is selected.
[0033]
Thus, when the next candidate selection operation is performed, the subsequent candidate programs are selected in the same manner. When there is no candidate program, the program is selected after returning to the first selected program.
[0034]
As described above , in the receiver of FIG. 1, a program can be selected in the three types of selection modes (1) to (3). Since the program itself is selected based on this, it is easy to select the target program. 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.
[0035]
The routine 100 shown in FIG. 5 is an example of a routine for realizing the “selection mode with priority on the latest history” in the above item (1). That is, for example, as shown in FIG. 4A, when the jog dial 22 is pressed while the cursor 231 is positioned in the selection mode of item (1), the CPU processing of the microcomputer 20 starts from step 101 of the routine 100. In step 102, the pointer is set in the first column of the data column of the data table 31 (FIG. 3A).
[0036]
Subsequently, in step 111, a service ID that matches the service ID at the position of the pointer set in step 102 is searched from the data table 33.
[0037]
Then, when the search result is determined in step 112 and there is a matching service ID, the process proceeds from step 112 to step 113, and in this step 113, the program with the matching service ID is selected, and thereafter In step 115, the routine 100 is terminated.
[0038]
If there is no matching service ID in step 112, the process proceeds from step 112 to step 121. In step 121, whether or not the pointer set in the data table 31 is located in the lowermost column of the data table 31. Is determined. If it is not located in the bottom column, the process proceeds from step 121 to step 122, where the pointer is moved to the next column of the data table 31, in this case, the second column, and thereafter The process returns to step 111.
[0039]
Therefore, thereafter, steps 111 to 122 are repeated for the service IDs in the data column after the second column of the data table 31 until a service ID matching the service ID is obtained from the data table 33. If there is, the program with the service ID is selected in step 113.
[0040]
In step 121, when the pointer is positioned in the lowermost column of the data table 31, the process proceeds from step 121 to step 115, and this routine 100 is terminated.
[0041]
In this way, according to the routine 100, the “selection mode with priority to the latest history” in the item (1) is realized.
[0042]
A routine 200 shown in FIG. 6A is an example of a routine for realizing the “selection mode by time zone / day of the week ” in the above-mentioned item (3). That is, when the jog dial 22 is pressed while the cursor 231 is positioned in the selection mode of the item (3), the processing of the CPU of the microcomputer 20 starts from step 201 of the routine 200, and then in step 202, the data The data in the table 31 is rearranged in order of time by comparing the “hour” of the time.
[0043]
Subsequently, in step 203, the data table 31 rearranged in step 202 is further rearranged with priority given to the current time and day of the week. Thereafter, in step 204, the same processing as in the routine 100 is executed using the data table 31 resulting from the step 203 and the data table 33, and channel selection is performed. In step 205, the routine 200 is terminated. .
[0044]
In this case, step 203 can be configured as a routine 300, for example. That is, in the routine 300, the processing starts from step 301. Next, in step 302, the current time and day of the week data are obtained from the clock circuit 25. Subsequently, in step 303, the data table 31 (FIG. 3A) is acquired. In the data column, a pointer is set in the “hour” data column that is the same as the “hour” of the current time acquired in step 302.
[0045]
Next, in step 304, of the data in the data table 31, data located from the first column to the data column before the pointer set in step 303 is moved to the end of the data table 31. In step 305, the data in the data table 31 processed in step 304 is rearranged in order of day of the week so that the current day of the week acquired in step 302 comes before the data having the same time “time”. Thereafter, the routine 300 is terminated by step 306.
[0046]
In this way, according to the routines 200 and 300, the “selection mode based on time zone / day of the week ” in section (3) is realized.
[0047]
7 and 8 show an example of the jog dial 22. That is, a printed wiring board 43 is fixed to the rear portion (right side in the figure) of the chassis 41, a rotary encoder 51 is provided on the board 43, and an input shaft (operation shaft) 52 is connected to the receiver through the through hole 42 of the chassis 41. It is located on the front side. The input shaft 52 has a hexagonal cross section, for example.
[0048]
The joint 61 is made of a metal or plastic material and has a cylindrical portion 62 and a flange portion 63 at the end of the cylindrical portion 62, and is integrally formed. For example, it is a hexagon. The input shaft 52 is gently inserted into the cylindrical portion 62 with the flange portion 63 on the rotary encoder 51 side.
[0049]
Further, at this time, a coil spring 65 is provided concentrically with the input shaft 52 between the flange portion 63 and the chassis 41, and the joint 61 is away from the rotary encoder 51, that is, in the forward direction of the receiver (see FIG. To the left). The cylindrical portion 62 is exposed to the front surface of the panel 45 through the through hole 46 of the front panel 45, and a knob 67 is inserted into the tip thereof, for example, and is fixed by bonding.
[0050]
The chassis 41 is provided with a micro switch 55, and an actuator (operation part) 56 of the micro switch 55 is opposed to the flange part 63.
[0051]
According to such a configuration, the knob 67 is fixed to the cylindrical portion 62 of the joint 61. Further, the cylindrical portion 62 is gently inserted into the input shaft 52 of the rotary encoder 51. However, since the cylindrical portion 62 and the input shaft 52 have a hexagonal cross section, they are rotationally rotated. Will be joined.
[0052]
Therefore, when the knob 67 is turned, the input shaft 52 is also rotated together through the joint 61, and a signal that changes in accordance with the rotation direction and the rotation angle of the knob 67 is output from the rotary encoder 51. Therefore, the movement of the cursor 231 displayed on the LCD 23 or the change of the selection mode can be executed by this signal as described above.
[0053]
When the knob 67 is pushed in the rear direction of the receiver, the joint 61 is displaced in the rear direction. At this time, the flange portion 63 of the joint 61 pushes the actuator 56 of the micro switch 53. Therefore, when the knob 67 is pressed, a switch output is obtained from the microswitch 55, and thus, the selection mode can be determined as described above.
[0054]
Thus, according to the jog dial 22, the selection of the selection mode can be executed by turning the knob 67, and the selection of the selection mode can be executed by pressing the knob 67.
[0055]
Although the selection mode is selected and determined by the jog dial 22 in the above description, it can also be performed by key operation.
[0056]
【The invention's effect】
According to this invention, 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.
