Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic program control device, and more particularly to a data collating method for obtaining an item to be controlled from a time information and control device information designated in control data in a television automatic program control device.

[0002]

2. Description of the Related Art Conventionally, in a data collating method in a television automatic program control device, a control timing is obtained from the transmission start time 8 and the current time designated in the program transmission control data as shown in FIG. The output code to be controlled to is obtained from the control table as shown in FIGS.

This control table is a time collation table 50.
, Control information table 60, and control output table 70
And an output code conversion table 80. The time collation table 50 is composed of a control timing 51 to be controlled, a collation condition 52 indicating whether control is possible at this control timing 51, and an address 53 of a control information table 60 indicating a control item when this condition is satisfied. (See FIG. 8).

Further, the control information table 60 has a control data reference position 61 indicating which item of the program transmission control data is referred to, a processing condition 62 indicating whether the referred contents satisfy a processing condition, and a processing condition 62. It is composed of the address 63 of the control output table 70 indicating the control item when the condition is satisfied (see FIG. 9).

Further, the control output table 70 has a control device code 71 indicating a control device to be controlled, a control item number 72 indicating the number of control items of this control device, and an output condition indicating an output condition in this control device. 73 and the output No. 73 when this condition is satisfied. And 74 (see FIG. 10). In the output code conversion table 80, this output number. The output code to be actually output to the control device is stored in correspondence with 74 (see FIG. 11).

As described above, since the control table has a structure divided according to the control timing, the control output table 7 indicates which control timing the control item controls.
It cannot be judged only by 0. Therefore, it is necessary to go back to the time collation table 50 in order to determine which control timing to control.

Therefore, when changing the control timing of the device or adding a control item, the time collation table 50, the control information table 60, and the control output table 7
0 The contents of each must be changed.

Further, in the conventional control table configuration, all control tables have to be referred to in order to obtain the output code of the device to be output under a certain condition, so that the control table becomes larger as the system scale increases, and the control table becomes larger. It takes time to refer, and the load on the CPU also increases.

[0009]

In the above-mentioned conventional data collating method, since the television automatic program control device controls according to the time, the control information table 60 is set for each control timing in the control tables shown in FIGS. Is defined, and the information is divided for each device in the control output table 70. Therefore, the time collation table 50, the control information table 60, and the control output table 70 can be used to change the control timing of the control item of a certain device. Modifications need to be made to the overall control table represented.

Further, in the control information table 60,
When the control items of the video device control information 9 and the audio device control information 10 of the program transmission control data shown in FIG. 2 increase, the contents of the control information table 60 also increase in proportion to the increase of the control items. Since all the control tables are referred to in the data collation, there is a problem that if the content of the control information table 60 increases, the control time will be affected by the increase of the content of the control information table 60.

Therefore, an object of the present invention is to provide an automatic program control device capable of easily changing and adding control information of each device and reducing the data collation time.

6 and 7 are flow charts showing the data collating process according to an embodiment of the present invention. These Figure 1
The data matching process according to the embodiment of the present invention will be described with reference to FIGS.

In the automatic TV program control device, the data collating process shown in FIG. 6 is performed by the time information interrupted from the time output device 4 every second. That is, the CPU 1 reads the current time from the time output device 4 (step S1 in FIG. 6), and fetches program transmission control data for performing data collation from the memory 2 (step S2 in FIG. 6).

The CPU 1 obtains the control timing from the current time from the time output device 4 and the transmission start time 8 of the program transmission control data (step S3 in FIG. 6), and the video equipment control information 9 designated in the program transmission control data 9 (Fig. 6
Step S4). The CPU 1 collates the control timing and the video equipment control information 9 with the control table (step S5 in FIG. 6).

When the collation with the control timing and the video equipment control information 9 is completed, the CPU 1 obtains the audio equipment control information 10 designated in the program transmission control data (step S6 in FIG. 6). At this time, the CPU 1 determines a match between the audio device specified in the audio device control information 10 and the video device for which the collation is completed (step S7 in FIG. 6). When a match is detected, the control timing and the audio device control information are detected. 1
The collation for 0 is omitted.

If no match with the video device for which the collation is completed is detected, the CPU 1 performs the same processing as in step S5.
The control timing and the voice device control information 10 are collated by the control table (step S8 in FIG. 6).

In the automatic TV program controller, the control process is
Although it is necessary to perform the verification within a second, it is not possible to verify all the program transmission control data registered in one verification process, so the data range to be verified is set in advance.

The CPU 1 checks whether the collation with the program transmission control data within this data range has been completed, and if not, repeats the processing of steps S2 to S9 until the program transmission control data is completed.

In the collation processing of steps S5 and S8 described above, first, the control device list table 20 is collated with the video device control information 9 or the audio device control information 10 (step S10 in FIG. 7), and the video device control information 9 or the audio is displayed. It is checked whether or not there is a device corresponding to the device control information 10 (step S11 in FIG. 7).

If there is a device corresponding to the video device control information 9 or the audio device control information 10, the device control timing is obtained by the control timing obtained from the present time from the time output device 4 and the program transmission control data transmission start time 8. Table 3
0 is compared (step S12 in FIG. 7), and it is checked whether or not there is a timing corresponding to this control timing (step S13 in FIG. 7).

If there is a timing corresponding to this control timing, the system determines that control timing value 31-1.
It is checked whether or not the control conditions 32-1 to 32-n of 31-n are satisfied (step S14 in FIG. 7). If the system satisfies the control conditions 32-1 to 32-n, the device control timing table 30 is collated (step S15 in FIG. 7), and the system outputs the output No. It is checked whether or not the output conditions set for each are satisfied (step S16 in FIG. 7).

The system outputs the output number. If each output condition is satisfied, the output No. The output code designated by is calculated from the output code exchange table 40, and output control is performed at the transmission start time 8 designated in the program transmission control data (step S17 in FIG. 7). When this output control is performed, the process returns to step 6 or step 9.

As described above, by making the control table independent for each device, even if the number of control devices or the system configuration is different, the control device list table 20 in the control table has the same number of devices. Code 2
Since 1-1 to 21-n can be registered and the device control timing table 30 and the output code exchange table 40 matching the control items and conditions of each device can be registered one-to-one with the device,
It becomes easy to create a control table.

Since the table structure is divided for each device, the device control timing table 30 to be compared with the video device control information 9 or the audio device control information 10 of the program transmission control data can be limited.
Unnecessary table collation is eliminated, the data collation time can be shortened, and the system scale is not affected. Therefore, the control information of each device can be easily changed and added, and the data collation time can be shortened.

[0040]

As described above, according to the present invention, the control information of each broadcast transmitting device is stored in correspondence with each broadcast transmitting device, and the time data of the control data for transmitting the video and audio and the present time are stored. When the coincidence with the time is detected, the control information of the broadcast transmitting device corresponding to this control data is read out, and the broadcast transmitting device is controlled based on the control information to change or add the control information of each device. This has an effect that it can be easily performed and the data matching time can be shortened.
