The present invention relates to a video cassette recorder (hereinafter referred to as a VCR), and more particularly, to a video cassette recorder for processing KBPS (Korea Broadcasting Program System) data using a personal computer.

KBPS converts the program reservation recording data into a digital signal on a television signal and inserts it into any one of the vertical blanking intervals of the video to be transmitted. This signal is demodulated by the KBPS decoder on the receiving side and broadcasted. It is a Korean TV reservation recording method that performs the scheduled recording and automatic time setting function.

In this case, the transmitted data includes standard time information of a broadcasting station, daily program information, information for updating in the case of a continuous program, and information for the case where one additional cancellation / change is preceded. Execution, preservation of scheduled recording data after power failure, automatic time setting function, detailed program information provision, broadcasting program classification, scheduled recording confirmation

1 shows a schematic block diagram of an apparatus for processing KBPS data.

Since data must always be input to the KBPS decoder, a tuner video input is input when the power is turned off, and an image signal passed through the video module is input through the switching unit 1 when the power is turned on. The image signal input through the switching unit 1 is separated from the synchronization unit 2. This separated synchronization signal is sent to the data slicer 3 and the decoder 4, where the data slicer 3 synchronizes to slice the digital data using the synchronization signal, and the decoder 4 synchronizes. The signal is used to synchronize the OSD as described later.

The digital data sliced in the data slicer 3 is decoded in the decoder 4. That is, the decoder 4 gives an address to the EPROM 5 in which a program for decoding KBPS data is stored, and the EPROM 5 gives the decoder 4 data stored at the address again to the decoder 4. ) Will work. At this time, necessary character data is received from the font ROM 6, and the decoder 4 outputs KBPS data decoded digital data when the KBPS data input from the VCR microcomputer 10 and the enable clock signal are applied. A D / A converter 7 is used to convert the digital data at this time into an analog signal, and the analog signaled final output is output through the switch 8. Reference numeral 9 is a storage unit made of DRAM.

As described above, the conventional KBPS device has a problem in that its configuration is complicated, so that the large size and high price of the VCR is caused in order to mount it on the VCR.

The present invention has been made to solve such a problem, and an object of the present invention is to perform a processing of KBPS data as a personal computer, so that a personal computer capable of processing KBPS data without configuring a separate KBPS data processing device in a VCR. It is to provide a KBPS data processing apparatus of a video cassette recorder using.

In order to achieve the above object, the present invention comprises a computer for processing the input image signal and the character signal corresponding to the input KBPS data and display on a computer monitor, and outputs a control signal corresponding to the user's control; A video cassette recorder connected to a computer, the video cassette recorder comprising: a tuner for receiving a broadcast signal of a predetermined channel; a deck capable of selectively recording and reading image signals on a video tape; A processing unit, a slicer that slices KBPS data from a tuner signal and applies it to a computer, a key matrix composed of a plurality of keys, a drive key of the key matrix, and a microcomputer controlling the drive of the tuner and the deck according to control signals from the computer. A video cassette recorder is provided.

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

2 is a schematic block diagram of a KBPS data processing apparatus of a video cassette recorder using a personal computer according to the present invention, where code 10 denotes a VCR and code 20 denote a general personal computer.

In the VCR 10, a tuner 11 is constructed as in the conventional VCR, and the tuner 11 is a predetermined frequency band of broadcast signals of radio frequencies transmitted from broadcasting stations under the control of the microcomputer 12. Receive the signal of.

The signals received by the tuner 11 are applied to the slicer 13, and the slicer 13 slices only KBPS data among the received signals and applies them to the personal computer 20 as in the prior art. In addition, the signal received by the tuner 11 and the video signal of the magnetic tape read out from the deck 14 are applied to the personal computer 20 after being reproduced through the signal processing unit 15.

At this time, the microcomputer 12 drives the above-described tuner 11, the signal processor 15, and the deck 14 by the signal applied from the key matrix 16 and the signal applied from the personal computer 20 described later. To control.

On the other hand, the personal computer 20 is configured with an internal nonvolatile memory device, for example, a CD-ROM, a hard disk, or a floppy disk. The character fonts corresponding to KBPS data are stored in these memory devices. The VCR 10, that is, the character signal corresponding to the KBPS data applied from the slicer 13 can be displayed on the monitor 30. In addition, the personal computer 20 converts the image signal applied from the VCR 10 into a monitor for the computer and displays the image signal received by the VCR 10 or reproduced by the deck 14. And the character signal by the KBPS data is displayed on the monitor 30 connected with the personal computer 20.

The personal computer 20 is configured to apply data corresponding to the information input by the keyboard of the personal computer to the microcomputer 12 of the VCR 10. Therefore, the user can input the reserved recording information for the desired program among the KBPS data displayed on the monitor 30 to the personal computer 20 through the keyboard, and the personal computer 20 inputs the input information to the VCR ( By applying to the microcomputer 12 of 10), the VCR 10 performs reservation recording in accordance with the reservation information input by the user.

The connection and configuration of the personal computer 20 and the VCR 10 are described in the connection control device and method (application number 95-22868) of a computer and a video cassette recorder previously filed by the present applicant. In the specification, detailed descriptions and illustrations are omitted.

As described above, the present invention has the effect of significantly reducing the production cost in implementing a device for processing KBPS data in a VCR by configuring a device for decoding KBPS data using an existing personal computer.
