JPH0744932A - Video tape recorder with correction function, such as delay and change of video recording reservation program - Google Patents

Abstract

PURPOSE:To enable automatic video recording with a video recorder for household by combining a video recording reservation timer of the video recorder for household, a microcomputer which reads the basic signals common to all broadcasting stations which is standardized and of which a part of sound or video channel bands is roded, and operation signals and a microcomputer of a receiver to be exclusively used for sub-codes. CONSTITUTION:Video recording starts at the assigned time but the previous program is broadcast for certain reasons. A signal is transmitted thereto from the broadcasting station. The video recording for household, which reads this signal, once releases the video recording system and stores the fresh start time and end time of video recording designated by the broadcasting station included the signal. A main power source is then turned off. Further, there is no need for resetting the video recording reservation even if the schedule for video recording for the purpose of special program broadcasting is delayed in broadcasting to another time frame after one month as an example of a development type using the sub-codes. The diligent control of the start time and end time of video recording is thus possible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home-use video tape recorder having a recording reservation timer having a correction function such as delay change of recording reservation programs.

[0002]

2. Description of the Related Art Even though a recording reservation timer for a home video tape recorder was set, unnecessary programs were recorded in the first half of the video tape due to the extension of baseball broadcasting and special programs. It was not uncommon that the latter half of the program that I wanted to record was not recorded, or that a completely different program was recorded.

[0003]

When recording a program of the same broadcasting station after the baseball relay on the broadcast day of the baseball broadcast, it is not necessary to bother to stay at home and perform a manual recording operation in real time.

Even when the recording reservation timer is used, it is not necessary to set a long time, and the video tape is not wasted.

Even if the broadcast program itself is postponed for a long term due to an emergency report or the like, the recording reservation is canceled and unnecessary recording is not performed.

In the advanced type using the so-called sub-code in the third channel band, once the recording reservation is set, it goes back before the setting date regardless of the G code recording reservation, the bar code recording reservation, the manual recording reservation, etc. Regardless of when and at what time it will be broadcasted, the home video tape recorder will automatically record as long as the standard signals and operation signals common to each broadcasting station are transmitted.

[0007]

According to the present invention, a recording reservation timer of a home video tape recorder and a standardized standard broadcasting station common basic signal and operation signal which encodes a part of an audio or video channel band are read. A simple system is obtained by combining a microcomputer capable of performing the above or a receiver dedicated to the sub-code and a microcomputer having the above-mentioned function.

In the advanced type using the so-called sub-code in the third channel band, a recording reservation timer having a function of converting the recording reservation into a standardized code and storing it, a receiver dedicated to the sub-code and a microcomputer. It should be combined while continuously energized.

In any case, if it is necessary to revise the Radio Law, a request for revision must be made immediately.

[0010]

[Effect] Even if the scheduled program broadcast time is delayed due to the extension of the baseball relay broadcast, the emergency broadcast, or the like, the audio or video channel band or the third channel is broadcast at the original scheduled program broadcast time.
By transmitting standard signals and operation signals common to all broadcasting stations that have standardized using the channel band, so-called sub-code, the home video tape recorder microcomputer that is turned on at a preset time and enters the recording system The signal is read and automatically changed to the start time and end time of recording specified by the broadcasting station. Also, for those who do not know when it will end, such as baseball relay broadcasting,
Control is possible by sending out standard signals common to all broadcasting stations and standardized operation signals frequently.

Further, in the advanced type using the so-called sub-code in the third channel band, the home video tape recorder stores the recording reservation time after setting and input, and it is also stored as a standardized code, and each standardized code is stored. Broadcasting stations Common base signals and actuating signals are constantly received, so even if the broadcasting date is postponed indefinitely or even if it is broadcast early within the range that does not go back before the set date, each standardized broadcasting station Even if the common basic signal and the actuation signal are transmitted, more thorough control can be performed over the day.

[0012]

EXAMPLE A G code reservation, bar code reservation, or manual recording reservation of a broadcast program is made with a home video tape recorder. Recording started at the designated time, but the previous program is being broadcast for some reason. A signal was sent from the broadcasting station to it, and the home video tape recorder that read the signal temporarily canceled the recording system and set the start and end times of the new recording specified by the broadcasting station included in the signal. Remember, the main power is turned off.

Further, as an advanced embodiment using the so-called sub-code in the third channel band, even if the recording reserved program is postponed to another time frame after one month due to the special program broadcasting, the recording reservation is reserved. There is no need to redo the settings, and theoretically, the start time and end time of recording can be controlled more diligently, so that waste of the video tape can be reduced. Furthermore, the memory circuit of the microcomputer allows a plurality of program recording reservation systems to be continued, and there is no problem with other program recording reservations.

[0014]

As described above, the present invention eliminates waste at the time of program recording reservation recording, and is safe even if the time of program broadcasting is delayed or changed due to extension of baseball broadcasting, express broadcasting, etc. It is a function that you can leave it to the recording reservation timer of your home video tape recorder.

Claims (4)

[Claims] 1. A G code recording reservation, a bar code recording reservation, or a manual recording reservation on a home video tape recorder, when a scheduled broadcast time is delayed due to extension of a baseball relay broadcast, emergency broadcast, or the like.
