Abstract

PURPOSE:To easily judge scheduled time for broadcasting a recorded program from date memory data by defining the data, to which a date is recorded to be superimposed to a video signal, as a target value. CONSTITUTION:By the exchange of the data between a decoder 6 and timer circuit 9, the real value of the broadcasting program is compared with the target value, which is set by a user in advance, and when these values are coincident, a VTR starts recording. At such a time, the timer circuit 9 outputs the signal corresponding to the data as the target value and the signal is inputted to a character recording circuit 3. In such a way, the date data to be sent from the timer circuit 9 are superimposed to the video signal to be outputted from a signal processing circuit 2 in the character recording circuit 3 and afterwards, the video signal is recorded through a recording amplifier 4 to a tape 8 by a video head 5 and displayed. Thus, the target value such as the scheduled time for broadcasting the program can be easily judged from the data to which the date is recorded.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is applicable to the recording of broadcast programs such as television broadcasts using a video tape recorder (hereinafter referred to as VTR). The present invention relates to a date recording device configured to record date characters of a program to be recorded.

[Prior Art] Generally, a video program system (Video Program System) is used for reserved recording of broadcast programs.
m: Hereinafter referred to as VPS). This vPS
The outline is as follows.

In other words, comments on each broadcast program are announced via print media such as newspapers and TV texts, and when a viewer views the print media and wants to record a program, the viewer sets and stores data related to that program in the VTR as a target value. let This set target value is compared with the actual value of the vPS code shown in the data string 16 of the video signal, and as long as both values match, the program is recorded.

According to such scheduled recording using a VPS, even if the time of the broadcast program is shifted, the broadcast program set in the VTR as a target value can be recorded without error.

As mentioned above, in the date recording device that records the date character overlappingly on the video signal of the broadcast program recorded by VPS, the conventional one
It is configured to record the current time when the S signal is broadcast and recording starts overlappingly with the video signal.

FIG. 4 is a block diagram showing the configuration of a conventional VPS date recording device. In the figure, (1) is a tuner;
(2) is a signal processing circuit, and (6) is a decoder, which receives the video signal received by the tuner (1) and decodes the PS data of the data string 16. (7) is a timer circuit that controls the receiving frequency of the tuner (1), scans the channel of the program set as the target value, and also controls the V input from the decoder (6).
The value of the PS data, that is, the actual value, is compared with the target value, and when the two values match, the broadcast program is recorded.

(3) is a character recording circuit, and this character recording circuit (3) receives the designation of the date character to be recorded by the control I@ signal output from the timer circuit (7), and duplicates the date character in the video signal. do. 0) is a recording amplifier that amplifies the video signal with duplicate date characters output from the character recording circuit (3) and outputs it to the video tape (5) via the video head (5).
8) Record on top.

Next, the operation of the above configuration will be explained.

In the following explanation, the set target f shift 1, for example, November 26, 1989 (SUN) 10:00-1
A case will be described in which a program on channel 3ch is broadcast from 10:30 at 1:00.

The video signal received by the tuner (1) is input to a signal processing circuit (2) and a decoder (8), respectively. At this time, the reception frequency of the tuner (1) is controlled by a control signal from the timer circuit (7), and the channel of the program set as the target value is scanned.

Next, the VPS data of the data string 16 of the video signal input to the decoder (6) is decoded and input to the timer circuit (7). This value, that is, the actual value, is compared with the set value/target value, and if the two values match, the VTR records this program.

On the other hand, the video signal input to the signal processing circuit (2) reaches the character recording circuit (3). The characters to be recorded here are specified by the control signal from the timer circuit (7). That is, the above-mentioned “89 November 26th (SUN) 10
:30 worth of data is sent and its date characters are superimposed on the video signal. In this way, the video signal with duplicated date characters is input to the recording amplifier 0) and amplified, and then sent to the tape (8) via the video head (5).
) and the date characters are displayed as shown in FIG.

[Problems to be Solved by the Invention] Since the conventional date recording device is configured as described above, since the date recorded overlappingly with the video signal is the current time, it is possible for the program to deviate from the scheduled time. If it is broadcast,
On the user side, it is difficult to accurately determine which target value a recorded program has based on date-recorded data.

This invention was made to solve the above-mentioned problems, and provides a date recording device that can easily determine target values such as the scheduled broadcast time of a program from date-recorded data. The purpose is to

[Means for Solving the Problems] A date recording device according to the present invention compares a preset target value and a broadcasted actual value, and when the two values match, prints the data of the target value as a character. It is characterized in that it is configured to output to a recording circuit.

[Function] According to the present invention, on the user side, the preset target value is output to the character recording circuit as date recording data and is recorded overlappingly with the video signal, so that the recorded date recording data cannot be displayed. This allows you to know target values such as the scheduled broadcast time of the program.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the configuration of a date recording device according to an embodiment of the present invention. In the same figure, the difference from the conventional example shown in FIG. 4 is the function of the timer circuit (8).
