Description

Method of continuous recording of video signals of the same kind of video cassette recorder

The present invention relates to a method of editing a video signal of a magnetic tape using two video cassette recorders. More particularly, the present invention relates to a method of editing a magnetic tape in which a video signal including information on a broadcast program is recorded in a vertical erasure section. The present invention relates to a method of continuously recording a homogeneous program video signal of a video cassette recorder for re-recording only desired broadcast program types among video signals.

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 the case of recording a broadcast signal on a magnetic tape using such a video cassette recorder, the broadcast signals recorded on the magnetic tape are not only related to one program type (i.e. sports, drama or news, etc.) but also various kinds of programs. The broadcast signal is recorded discretely. Therefore, when the user selects only the broadcast signal for the same type of program from among the broadcast signals recorded on the magnetic tape and wants to continuously play and watch the video, the video cassette recorder is driven in a fast forward mode or the like. It was inconvenient to search the section of the magnetic tape on which the program was recorded.

Therefore, some of the users use two video cassette recorders to reproduce the video signals recorded on the magnetic tape with one video cassette recorder, and only the desired video signals of the reproduced video signals are different with the other video cassette recorder. By selecting and recording a magnetic tape, a method of producing a magnetic tape in which only a desired video signal is recorded is adopted. However, in the conventional method using two video cassette recorders, one video cassette recorder must be driven in the playback mode while the other video cassette recorder must be driven sequentially in the recording and stop modes, which is a great inconvenience for the user. It is causing.

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 the present invention, 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 the programs, in a horizontal erasing section of the broadcast signal.

The program information in the disclosed invention is configured to include program type information indicating whether the broadcast program is drama, news, or sports. The present inventors use such program information, and among the broadcast video signals recorded on the magnetic tape, It was conceived that only images of the desired program type could be recorded on another magnetic tape.

SUMMARY OF THE INVENTION The present invention has been made in view of this concept, and an object of the present invention is to select only a broadcast program desired by a user on another magnetic tape by using broadcast program type information in a horizontal erasure section of a broadcast video signal recorded on a magnetic tape. The present invention provides a method of continuously recording a homogeneous program video signal of a video cassette recorder.

In order to achieve the above object, the present invention provides a driving method of a second video cassette recorder which receives a video signal of a magnetic tape from which a video signal including program type information is recorded in a horizontal erasing interval from a first video cassette recorder. Determining whether a playback mode is set; If a reproduction mode is set, determining whether a program type of a video signal is selected; If the program type of the video signal is not selected, recording the video signal of the first video cassette recorder on a magnetic tape; If the program type of the video signal is selected, recording the video signal of the first video cassette recorder on the magnetic tape only when program information identical to the selected program type is detected from the video scene of the first video cassette recorder.

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 television broadcasts according to the present invention, wherein the first video cassette recorder 10 and the second video cassette recorder 20 are interconnected via a line 30.

Here, the first video cassette recorder 10 is a general video cassette recorder capable of recording and reproducing video signals, and the second video cassette recorder 20 is a video cassette recorder capable of carrying out the present invention. The video cassette recorder 20 for carrying out the present invention further has a vertical erasure interval detecting unit as described later. In this specification, the configurations of the video cassette recorders 10 and 20 have been described at the same time.

That is, the tuners 11 and 21 in the video cassette recorders 10 and 20 receive the signals of the channels corresponding to the tuning signals of the microcomputers 12 and 22 and apply them to the recording processing systems 13 and 23, and record processing. The systems 13 and 23 are configured to record and apply the received broadcast signals of the tuners 11 and 21 to the decks 14 and 24 in accordance with the recording control signals of the microcomputers 12 and 22.

The decks 14 and 24 drive in the recording mode when the recording control signals are applied from the microcomputers 12 and 22 to record the broadcast signals of the recording processing systems 13 and 23 on the magnetic tape, and from the microcomputers 12 and 22, respectively. When a reproduction control signal is applied, it is configured to drive in the reproduction mode to read out the broadcast signal recorded on the magnetic tape and apply it to the reproduction processing systems 15 and 25.

On the other hand, the decks 14 and 24 of the present invention are configured to drive in the fast playback mode, the pause mode, or the like according to the control signal from the microcomputer 2.

As shown, the key metrics 17 and 27 are connected to the microcomputer 12, and function keys (channel selection keys (usually composed of numeric keys), power on / off keys, and playback keys of the key metrics 17 and 27) are connected. And the like, and the key matrix 27 in the video cassette recorder 20 of the present invention includes keys for selecting a program type in addition to these keys, for example, a sports selection key, a drama selection key, a news selection key, and the like. The microcomputer 22 performs the operation described below in accordance with the driving of these keys.

On the other hand, signals reproduced by the reproduction processing systems 15 and 25 are output to the modulator 18 28, and the modulators 18 and 28 transmit these signals to frequency signals of predetermined channels (typically three or four channels). Is modulated and output.

In addition to the above-described configuration, the video cassette recorder 20 of the present invention is connected with a horizontal erasing section detector 26 for inputting a received signal of the tuner 21, and the horizontal erasing section detector 26 is a horizontal signal signal. The erase section is detected, and program information included in the section is read out and applied to the microcomputer 22.

2 shows a flowchart of a program for the method of the present invention performed by the microcomputer 22 in the video cassette recorder 20 having the above-described configuration.

In this case, in order to carry out the present invention, the video signal of the magnetic tape loaded in the deck 14 of the video cassette recorder 10 is a recording of a signal transmitted from a broadcasting station. It should be apparent to those skilled in the art that the information on the broadcast program should be included in the horizontal erasing section from the following description. In addition, the video cassette recorder 10 is driven in the playback mode, and the deck 14 reads out the video signal from the loaded magnetic tape and applies it to the playback processing system 15, which plays the video. The signal is reproduced and applied to the modulator 18. The modulator 18 is in a state in which the reproduced video signal is modulated as a broadcast signal of a predetermined channel and applied to the video cassette recorder 30 as described above.

In addition, the video cassette recorder 20 of the present invention records the signal received by the tuner 21 in the recording mode. In this embodiment, the channel received by the tuner 21 is modulated by the modulator 18 and output. It is assumed that the channel is, but the scope of the present invention is not limited to this manner will be readily understood by those skilled in the art from the following description.

In the video cassette recorder 20 of the present invention, the microcomputer 22 determines whether the recording mode is set by the key driving of the key matrix 27 (S1). If the recording mode is set, the process proceeds to step S3. Program selection keys (sports selection key, drama selection key, news selection key, etc.) of the key matrix 27 are driven to determine whether one type of program is selected (S3).

As a result of the determination in step S3, if the program selection key is not driven, the microcomputer 22 causes the video cassette recorder 20 to operate in the normal recording mode so that the tuner 21 receives the signal of the modulator 18 channel. The recording processing system 23 records the received signal of the tuner 21 and applies it to the deck 24, and the deck 24 records the signal of the recording processing system 23 on the magnetic tape ( S5).

However, as a result of the determination in step S3, when the program selection key is driven, the microcomputer 22 inputs the program information of the video signal received from the vertical erasure section detection section 26 to the tuner 21, and this program information. If it is determined that the program type of the broadcast video signal currently being received is the same as the program type selected by the program selection key, the process proceeds to step S9 and, if it is the same, to step S11.

In step S9, the microcomputer 22 continues the tuner 21 and the recording processing system 23 to continue the above-described recording mode, while the deck 24 performs the temporary stop mode to stop the recording mode. The type of program not selected by the user among the signals received at 21 is not recorded on the magnetic tape in the deck 24.

However, in step S11, that is, when the signal of the program type selected by the user is received by the tuner 21, the microcomputer 22 is a video cassette recorder, that is, the tuner 21, the recording processing system 23 and the deck 24. ) Is recorded in the recording mode by recording the signal of the tuner 21 on the magnetic tape.

However, the process of recording on the magnetic tape only for the program type selected by the user by such steps S7, S9, and S11 ends when the user drives the program type deselection key of the key matrix 27. That is, the microcomputer 22 determines whether the program type selection key of the key matrix 27 has been driven in step S15, and when the program type selection key is driven, the user returns to step S3 so that the user can make a new program. You can select only the type to record on the magnetic tape, or select the normal recording mode.

However, when the program type selection key is not driven in step S13, or when the recording stop key of the key matrix 27 is pressed in step S5 (S15), the microcomputer 22 performs step S17. In step S17, the recording process is terminated in the normal recording mode or the selected program type, and the drive of the tuner 21, the recording processing system 23, and the deck 24 is stopped (S17). )

That is, when the first video cassette recorder reads and reproduces the video signal of the magnetic tape, and the second video cassette recorder records the reproduced video signal on the magnetic tape, the program information included in the vertical erasing section of the reproduced video signal is recorded. Therefore, the second video cassette recorder can selectively record only the video signal of the program type selected by the user.

As described above, the present invention has an effect that the process of re-editing only the video signal of the desired type among the video signals recorded on the magnetic tape can be easily performed.
