Figure 7 shows the time flow of the operation of the viewing situation survey device related to this embodiment. First, the 'Differentiator 213' will start to calculate the horizontal synchronizing pulse passing through the MPU252, such as the synchronous separation circuit 205, in the form of a passing pulse (pulse 03). In addition, those pulses that are input to the calculator 213 via the data selector i 2 2 and are to be calculated are increased by 4 times the subcarrier 4 times the transmitter 2 09 to increase the frequency to 4 times (^ 31818 MHz) Subcarrier.

As a result, when the signal of the channel of ⑻ and input 2 is input, the MPU252 will select the signals for the different transmission plural channels to the τν tuner via the I2COM transmission wheel & (Figure 4). This, and the comparison of the synchronization signal is performed continuously, from the first week to the next frequency channel appears. Or, you can get the same frequency for all J :, and repeat the same action. For the channel 11 or part of the channel, during the scanning period, t = the channel will be performed from these complex channels, and the horizontal synchronization pulse is compared with the vertical synchronization pulse. The channel is consistent. On the other hand, when the channels with the same frequency are the same, there is still a number of channels for viewing. The maximum or minimum value of the difference value is used to determine the strains that meet the same channel. The time of ^ + rush is 0. 0 698 " S f under the main situation ° and 疋 * send the calculator 21 3 pulse integer, in篦 nf must satisfy the calculator 213 respectively: the number of the calculator 213 (such as: 30) and 91 η / of the second fixed number (such as: 91). The integer of the calculator 213 is within the specified range (such as: If it is within 3 ～ 0 ~ Evening and Early / and 910), it is determined that the channels are different. Another example of Niu Gu is 5 children. The reason why the channel consistency is more than 91 0 is because in the digitally processed VCR, the picture signal from STB is equal to the daytime signal break. During the horizontal scanning period When it is Η, the loop processing is general as shown in the following formula, and there is a delay. 1 (H) △-(63.5 # S-0 to 2 // S) This value can be changed as appropriate. Fig. 8 is a view showing the behavior of the viewing situation investigation device related to this embodiment.

Workflow. In this flow, it is mainly explained that the comparison section 2000 comparing the horizontal and vertical synchronization signals described above. First, the comparison unit 200 can determine whether the power of the TV 118 is turned on by the power ON / OFF determination unit 253 (S301). Secondly, the TV tuner 101 can set the TV broadcast channel that can be accepted by STB through MPU252. Furthermore, the MPU252 determines which of the analog switches of the analog / data selector 1 1 0 is in the terminals I N 2 to 4 (S 3 0 5). The daytime signal transmitted to the TV 1 1 8 via the analog switch of the analog / data selector 11 0. If the STB is transmitted to the TV 118, the comparison unit 200 will not operate. On the other hand, in MPU252, when the analog switch of the analog / data selector 1 10 is in terminals IN 2 ~ 4 in stage S3 05, it will give the TV tuner 1 001 channel selection signal, and then the signal starts. Scanning of all channels (S307). In addition, the MPU2 52 will also send the horizontal synchronization pulses from the synchronization separation circuit 205 and the synchronization separation circuit 20 7 to the pulse 0 03 and the pulse 0 2 respectively, and then start the horizontal synchronization pulse for the channel. Phase difference comparison (S3 0 9) ° MPU252 will store the comparison results, such as: the channels determined to be consistent, stored in the memory section 2 5 4. Secondly, MPU252 will refer to the memory unit 254, and determine whether there is a consistent channel at the result of stage S30 9 (S 3 11), and when there are consistent channels, it will again determine whether the consistent channels are plural. (S313). When there is one consistent channel in the step S313, the Mpu252 judges this channel as a video channel, and transmits the recording data related to the viewing status to the memory section 254 (S315). In addition, in phase S3U, if there is no consistent channel, MPU252 repeats the operation of phase 8305 again.

9L Case No. 90113001 _η Revision V. Description of the Invention (15) On the other hand, when the consistent channel is plural in stage S3 1 3, the MPU252 will send a channel selection signal to the TV frequency selector 101 and set the plural consistency Channel (S317). In addition, the MPU252 will also send the vertical synchronization pulses from the synchronous separation circuit 2 05 and the synchronous separation circuit 2 07 to the pulses 0 0 3 and 0 02 respectively, and then start the phase difference comparison of the vertical synchronization pulses for the channel. (S31 9). Secondly, MPU252 will determine whether there is a consistent channel (S321). If there is no consistent channel, Mpu252 will repeat the operation of stage S305 again. On the other hand, when there are coincident channels in stage 3321, the MPU252 determines whether the coincident channels are plural (3323). If there are no coincident channels, the MPU252 performs the operation of stage S3 15 and ends the above processing. In addition, when there is a plurality of consistent channels in stage 3323, the maximum or minimum value of the calculated value is used to determine the viewing channel, which is stored in the memory section 254, and then the predetermined number of stages S3 is repeated again. Future assignments. In addition, in the above-mentioned flow, the comparison of the ^ flat synchronization pulse is performed first, but in the phase 3307 ~ ^ 13, the comparison of 7 vertical synchronization pulses is performed, and then in the phases S 3 1 9 to S 3 The comparison of 2 3 'ίΓίΛ flat synchronization pulses is actually okay. FIG. 9 is an explanatory diagram of recorded data stored in the memory unit 254.

[Invention effect] If According to the present invention, the day-to-day audio signals are viewed and compared synchronously, such a check. In addition, when the operation of the present invention is used to grasp the power of a TV, it will be achieved together with the viewing record. Say

Correct the personal data, or the record input section 2 5 5 that the individual has watched, and enter them. It is also counted in the items where data is recorded. In addition, the measured value is also input into the viewing time column. As explained above, for the actual positive signal and the sound signal of the picture received through it, you can correctly adjust the viewing status for another purpose. By confirming the CRT motion of the TV, when there is no daytime It can be projected on the CRT to register the audiovisual OFF status.
