How to schedule recording of a video cassette recorder

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video cassette recorder capable of receiving television broadcasts, and more particularly, to a reserved video recording method of a video cassette recorder for performing reserved recording using broadcast program information transmitted from a broadcasting station.

A video cassette recorder is a video device that records video signals on a magnetic tape by using the magnetism of a magnetic tape, or reads and reproduces a video signal recorded on a magnetic tape. Some video cassette recorders allow a broadcast video signal to be recorded on a magnetic tape by configuring a tuner capable of receiving a broadcast signal therein. In addition, a microcomputer is configured in the video cassette recorder to control the driving of the video cassette recorder, and a model in which a timer is configured in the microcomputer to enable reserved recording has been developed and used. That is, if the user sets the reserved recording start time, the reserved recording end time, and the reserved channel in the microcomputer, the microcomputer checks the current time of the timer and if the current time is the reserved recording start time, the tuner sends the broadcast signal of the reserved channel to the tuner. The received broadcast signal is recorded and the recording operation is stopped if the current time is the reserved recording end time.

On the other hand, reservation recording is performed for a broadcast program desired by a user, and information on the broadcast program is provided through a newspaper or the like. That is, the user views the broadcast program guide information and sets the broadcast start time of the desired broadcast program as the recording start time and the broadcast end time of the broadcast program as the reserved recording end time. However, broadcast programs may be broadcast earlier or later than the scheduled time due to the circumstances of the broadcasting station, and similarly, the broadcast end time may be earlier or later than the scheduled time. In this case, according to the conventional reservation recording method, a problem that a user does not want to record or a desired broadcast may not be recorded may occur.

On the other hand, the inventor of the present application has filed "broadcast program transmission apparatus and method (application number No.)" with the same as the present application. In this application, the present inventor has disclosed an apparatus and method for transmitting information on a broadcast program, that is, a program and a broadcast time to be broadcasted later and information on types of these programs within a horizontal erasing interval of a broadcast signal.

The inventors of the present application have conceived that by using the broadcast program information presented in the present invention, the user can completely record a desired broadcast program.

SUMMARY OF THE INVENTION The present invention has been made in view of this concept, and an object of the present invention is to reserve a video cassette recorder capable of perfectly recording a reserved broadcast program by using broadcast program information contained within a horizontal erasing period of a broadcast video signal. To provide a recording method.

In the reservation recording method of the video cassette recorder according to the present invention, a video signal is transmitted by including information including a program name, a channel and a time that is currently being broadcast in a horizontal erasing interval, and a broadcast program to be reserved by using program information. A reservation recording method of the selected video cassette recorder, comprising: determining whether a reservation recording mode is set; If the reserved recording mode is set, determining whether the current time is a predetermined time from a broadcast start time of the reserved program; Receiving a video signal of a channel corresponding to a channel of the reserved program if the current time is before a predetermined time at which the scheduled program starts broadcasting; Determining whether a current program name in a vertical erasure section of the received broadcast video signal is the same as a reserved program name; If the current program name in the vertical erasure section of the received broadcast video signal is the same as the reserved program name, the received broadcast video signal is recorded until the current program name in the vertical erasure section of the received broadcast video signal is different from the reserved program name. It includes a step.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a video cassette recorder capable of receiving a television broadcast according to the present invention, in which the tuner 1 receives a signal of a channel corresponding to the tuning signal of the microcomputer 2 and applies it to the recording processing system 3. The recording processing system 3 is configured to record and apply the received broadcast signal of the tuner 1 to the deck 4 according to the recording control signal of the microcomputer 2.

The deck 4 is driven in the recording mode when the recording control signal is applied from the microcomputer 2 to record the broadcast signal of the recording processing system 3 on the magnetic tape, and the reproduction mode when the reproduction control signal is applied from the microcomputer 2. And read out the broadcast signal recorded on the magnetic tape and apply it to the reproduction processing system 5. The reproduction processing system 5 reproduces the video signal of the deck 4 and applies it to the OSD unit 7. The OSD unit 7 generates a predetermined OSD character according to the contents of the microcomputer 2 and reproduces the OSD signal. It is mixed with the reproduced video signal of 5) and applied to a monitor (not shown).

On the other hand, the signal received from the tuner 1 is connected to the horizontal erasing section detecting section 6, the horizontal erasing section detecting section 6 detects the horizontal erasing section of the image signal, and the program information contained in the section It reads out and is applied to the microcomputer 2.

As shown, the key matrix 7 is connected to the microcomputer 2, and in addition to the function keys (channel selection key (usually composed of numeric keys), power on / off key, playback key, etc.) of the key matrix 7 As described later, a key for performing reserved recording, for example, a reserved recording setting key, etc., causes the microcomputer 2 to operate as described later in accordance with the driving of these keys.

2 shows a flowchart of a program for causing the microcomputer 2 to perform the method of the present invention in the video cassette recorder of the above-described configuration.

Here, in carrying out the present invention, the method for setting information for reserved recording, i.e., reserved channel, reserved recording start time and reserved recording end time, is different from the conventional method. That is, in the above-described configuration, the reservation information about the broadcast program is applied to the microcomputer 2 from the horizontal erasing section detection unit 6, and the microcomputer 2 applies these reservation information to the OSD unit 7 as OSD characters. The user can watch information (program name, broadcast time and program type, broadcast channel, etc.) about the broadcast program to be performed or to be performed on the monitor. This method has been described in detail in the "Applicant program display method (application number No.) of the broadcast signal receiving apparatus" filed by the applicant as the same as the present application, the description is omitted herein.

When the broadcast program is displayed on the monitor as described above, the user can select among the displayed broadcast programs to be scheduled recording using the key of the key matrix 8, and such a technique is generally used in the technical field of the present invention. The detailed description is omitted since it can be easily realized by a person with knowledge of the above. When reservation recording is performed in this manner, the microcomputer 2 stores information about a program to be reserved recording, that is, a name of a reserved recording program, a broadcast start time and end time of the reservation recording program, and the like.

According to the present invention, reservation recording is performed according to the reservation program information set through the above process. That is, the microcomputer 2 of the present invention determines whether the reserved recording mode is set in step 11 as shown, that is, information for reserved recording is stored, and if the reserved recording mode is set, step 13 Proceed to

In step 13, the microcomputer 2 determines whether the current time of the timer is 10 minutes before the predetermined time, preferably 10 minutes before the broadcast start time of the scheduled recording program, and drives the tuner 1 if it is before the predetermined time. Apply a tuning signal that causes 1) to receive a broadcast signal of a channel for receiving the program (step 15).

Accordingly, the tuner 1 receives the broadcast signal of the corresponding channel, and the horizontal erasing section detector 6 reads program information included in the horizontal erasing section among the received signals of the tuner and applies it to the microcomputer 2. Done.

At this time, the microcomputer 2 determines whether the current program information, that is, the name of the program currently being broadcasted, matches the reserved program name among the program information applied from the horizontal erasing section detection unit 6 (17). Proceeding to step 23, the recording control signal is outputted to record the broadcast video signal of the tuner 1 on the magnetic tape, but if it does not match, step 19 is reached.

That is, the broadcast program transmitted from the broadcast station may be canceled due to the circumstances of the broadcast station. In this case, even if the microcomputer 2 continues with step 17, the broadcast program name matching the reserved program name is horizontal. It will not be applied from the erase section detection section 6. Therefore, in the present invention, step 17 may be performed for a predetermined time or more (normally, the delay time of the broadcast is less than 20 minutes, so in the present embodiment, about 30 minutes is preferable). If the matching information is not applied from the horizontal erasure section detection section 6, the reservation recording mode of the reserved recording program corresponding to the current time is canceled and all processes are terminated (step 21).

On the other hand, the microcomputer 2 which has driven the recording processing system 3 and the deck 4 in the recording mode by step 23 proceeds to step 24, and the present of the program information of the horizontal erasing section detection section 6 is present. It is judged whether or not the name of the program being broadcast is different from the name of the reserved program, and if it is different, the driving of the tuner 1, the recording processing system 3, and the deck 4 is stopped to terminate the execution of the recording mode.

That is, the microcomputer 2 ends the performance of the recording mode when the broadcast program received by the tuner 1 is different from the reserved broadcast program.

As can be seen from the above description, in the reserved recording method of the present invention, it is determined by program information included in the horizontal erasing section of the broadcast video signal to determine whether a program currently being broadcast is a reserved broadcast program. Only broadcast programs can be recorded accurately.

As described above, the video cassette recorder of the present invention has the effect that only the broadcast program reserved by the user can be accurately recorded in the magnetic tape.
