KR960019234A - Video recorder that can display video on computer monitor - Google Patents

Abstract

The present invention relates to an image recording and reproducing apparatus capable of displaying an image on a computer monitor. The video recording and reproducing apparatus of the present invention includes a video signal converting means for converting a video signal so that the received video or a video signal reproduced from a recording medium can be displayed on a high resolution computer monitor. The video signal converting means includes a color signal separator, a synchronous signal separator, a clock doubler which increases the frequency of the separated horizontal synchronous signal to match the horizontal frequency used in the VGA monitor, and separate color signals R, G, B) a memory for storing the memory, a memory manager for controlling the writing and reading of the memory so that the color signals stored in the memory coincide with the horizontal scan line of the VGA monitor, a clock generator for operating each component, and horizontal and vertical synchronization with the color signals. It consists of a connector for transmitting signals to the VGA connector.

Accordingly, the present invention provides an effect of displaying the video signal of the video recording and reproducing apparatus on a high resolution computer monitor without the purchase of a separate device.
