Abstract

PROBLEM TO BE SOLVED: To record only desired information without setting time by providing control means for controlling a recording start or stop in a recording medium based on the result of comparison made by a comparing means. SOLUTION: A signal inputted from a device 11 which receives images or voice signals is compared with the recorded content of a storage device 12 for storing images or voice signals by a comparing device 13. When a program to be recorded by a user is started, a title or an announcement stored beforehand by the user is broadcast, the starting of the program to be recorded by the user is detected by the comparing device 13 and then the program is recorded in a device 3 for recording/ reproducing images or voices.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus, and more particularly to a video tape recorder for recording images and sounds of a broadcast program.

[0002]

2. Description of the Related Art At present, many video tape recorders are widely used in consideration of user's convenience and are multifunctional.
Hereinafter, an example of a conventional video tape recorder will be described with reference to the drawings.

FIG. 2 is a block diagram for explaining the operation of a conventional video tape recorder. In FIG. 2, 1 is a recording start timer, 2 is a recording end timer, and 3 is a recording / reproducing device (video tape recorder).

The operation of the video tape recorder configured as described above will be described below. First,
The user sets the time to start recording in the recording start timer 1. Subsequently, the user sets a time to end the recording in the recording end timer 2.

When the time to start recording comes, the recording / reproducing apparatus 3 starts recording by a signal from the recording start timer 1. Thereafter, when the time to end the recording comes, the recording / reproducing device 3 ends the recording by the signal from the recording end timer 2.

[0006]

However, in the above-described configuration, if the reference clock is out of order for some reason, for example, when recording a broadcasted program, the broadcast time may be reduced due to the convenience of the broadcasting station. If it is changed, the image or sound desired by the user cannot be recorded correctly.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. For some reason, when the reference clock is out of order or when a broadcasted program is recorded, for example, It is an object of the present invention to provide a recording / reproducing apparatus which can correctly record a program desired by a user even when the broadcast time is changed for convenience.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a means for receiving an image or sound signal, a means for storing an image or sound signal, the received image or sound signal, and the storage. Means for discriminating the difference between the input and output signals. When it is determined that the input image or audio signal is the same as the stored signal, the signal recording is started or terminated, thereby providing a reference clock. Provided is a recording / reproducing apparatus capable of correctly recording a program desired by a user even when the broadcast time is changed or the broadcast time of a broadcasted program is changed due to a broadcast station.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below.

FIG. 1 shows one embodiment of the present invention.
It is a block diagram of a recording / reproducing apparatus. As shown in FIG.
The recording / reproducing apparatus according to the present invention includes a device 11 for receiving an image or audio signal, a storage device 12 for storing a signal input from the device 11 for receiving the image or audio signal, and a device for receiving the image or audio signal. A comparison device 13 for comparing a signal input from the device 11 with a storage content of a storage device 12 for storing a signal input from the device 11 for receiving an image and a sound signal; and a device 3 for recording and reproducing an image and a sound. ing.

Generally, when a specific program starts, a fixed screen (title) or an announcement is broadcast. The user can specify the title and announcement of the program that the user wants to record,
It is stored in advance in a storage device 12 that stores a signal input from a device 11 that receives an image or an audio signal. The signal input from the device 11 for receiving the image and the audio signal is compared by the comparing device 13 for comparing the content of the storage device 12 for storing the image and the audio signal. When the program that the user wants to record starts, the title and the ounce that the user has stored in advance are broadcast, and the comparison device 13 detects that the program that the user wants to record starts, and the device 3 that records and reproduces images and sounds The program is recorded.

As described above, the present invention can record a program desired by a user regardless of the presence or absence and accuracy of a clock in a recording / reproducing apparatus, and even if a broadcasting station changes the broadcasting time. .

The signal to be stored in the storage device 12 may be a signal from which the features of the title or the announcement are extracted or thinned out. A signal that is not displayed or output as an image or sound may be added to the broadcast signal and stored in the storage device 12.

The comparison may be made by the comparing device 13 and the recording may be started with a judgment other than a perfect match. Any program that can detect that the user wants to record the program may be used.

[0015] The present invention can also be applied to end the recording of a program by a user. Further, signals recorded in the present apparatus are not limited to image and audio signals. For example, the present invention can be applied to any signal as long as it is distributed using a broadcast such as a computer program and text information.

[0016]

According to the recording apparatus of the present invention, only desired information is recorded without setting time in an information distribution system such as a broadcast where transmission start and stop cannot be controlled on the receiving side. It becomes possible.
