Description

Video cassette recorder that can be connected to a cassette recorder

The present invention relates to a video cassette recorder (hereinafter abbreviated as V-seal), and more particularly, to a V-al in connection with a cassette recorder to record only the audio signal of the V-seal.

V-Cal is a device that records and outputs video and audio signals on video tape or reads and outputs video and audio signals recorded on the video tape by selectively magnetizing the video tape which is magnetic material by using the magnetic head mounted on the rotating head drum. to be.

In recent years, satellite tutoring has become popular among candidates for college entrance. Satellite tutoring is a broadcast program created for the purpose of supplementing school classes and relieving overheated tutoring. It is an advantageous program that viewers can watch later using the above-described recording media such as VRC.

At this time, since the V-seal must be provided in order to watch the recorded tutoring program, there is a disadvantage in that there is no flexibility in viewing. That is, since V-alarms and televisions cannot be moved at all times, there is a problem that the user has to visit the place where V-alal is provided to watch contents recorded on the videotape.

In addition, the busy candidates do not have to watch video and audio simultaneously.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a V-Cal to perform recording of a learning program more efficiently by recording only an audio signal of the V-Cal into a cassette recorder.

That is, the present invention, in the V-Cal which can be connected to the cassette recorder, a tuner for receiving a broadcast signal; An audio signal separator for separating and outputting only an audio signal of a received broadcast signal; An L / R connection unit for connecting and filtering the separated audio signal to the cassette recorder; When the audio-only recording key signal is applied, it controls to output only the audio signal of the received broadcast signal, and provides a VR comprising a control unit for outputting the recording drive signal to the cassette recorder.

The above object and various advantages of the present invention will be described in detail with reference to the accompanying drawings.

1 is a connection block diagram of a cassette recorder 30 and VRC 10 according to the present invention, which includes a tuner 11, a recording processing system 12, a key input unit 13, a microcomputer ( 14), audio signal splitter 15, deck 16, OSD (On Screen Display) 17 and speaker 18, and L / R (left / right) connection 20 connected to V-Cal 10 And the cassette recorder 30, respectively.

As shown, the tuner 11 is configured to receive a broadcast signal of a channel corresponding to PLL data L1, which is a tuning signal of the microcomputer 14, among a plurality of broadcast frequency signals transmitted from the broadcast system. The broadcast signal is output to the recording processing system 12.

The recording processing system 12 processes the video and audio signals provided from the tuner 11 into recordable signals and outputs them to the deck 16 under the control of the microcomputer 14 (L2). Such recording processing system 12 The audio signal separation unit 15 is connected to the.

That is, the audio signal separating unit 15 separates only the audio signal from the above-described video and audio signals and provides it to the external cassette recorder 30.

Meanwhile, the key input unit 13 includes a plurality of function keys for controlling the operation of the V10, such as a power on / off key, and an audio selection key for recording only an audio signal according to the present embodiment (not shown). And a key signal corresponding to a key input, that is, pressed by a user, to the microcomputer 14.

The deck 16 includes a capstan motor and a reel motor for driving the video tape, and a video and audio head for recording and reading video and audio signals, respectively, and according to the control L3 of the microcomputer 14. The video signal of the recording processing system 12 is recorded on a video tape, or the signal of the video tape is read and applied to a reproduction processing system not shown.

The OSD 17 processes the video signal provided from the deck 16 under the control L4 of the microcomputer 14 into a displayable signal and provides a television screen, not shown, and the speaker 18 is provided from the deck 16. It has a function of transmitting the provided voice signal to the outside.

The L / R connection unit 20 according to the present embodiment is composed of an L / R jack and the like, and the cassette recorder 30 performs L / R filtering on the audio signal provided from the above-described audio signal separation unit 15. The cassette recorder 30 records this audio signal on a predetermined cassette tape under the control of the microcomputer 14.

In other words, the cassette recorder 30 has the same configuration as a conventional audio cassette recorder and is driven to record on the basis of the audio recording control signal of the microcomputer 14. In addition, this fact will be readily apparent to those of ordinary skill in the art.

The microcomputer 14 according to the present invention selectively controls the above-described components, and controls to record only the audio signal of the broadcast signal from the tuner 11 in response to the audio recording dedicated key signal from the key input unit 13.

That is, the microcomputer 14 controls the audio signal separating unit 15 to separate only the audio signal among the broadcast signals recorded by the recording processing system 12 according to the audio recording dedicated key signal, and the cassette recorder 30 uses a predetermined cassette tape. Recording control is to record such audio signal in.

As described above, the present invention has the effect of selectively watching the satellite tutoring program by selectively recording only the audio signal of the broadcast signal received by V-Cal using an external cassette recorder.
