Abstract

본 발명은 비데오 카세트 레코더의 고속탐색장치에 관한 것으로서, 2헤드 비데오 카세트 레코더를 이용하여 고속탐색시에 깨끗한 화질을 제공하기 위하여 제2비데오 헤드에 의해 검출된 제1트랙의 영상신호를 스위칭하는 제1스위칭수단과, 제1스위칭수단을 통하여 인가된 제1트랙의 아날로그 영상신호를 디지탈 영상 신호로 변환하는 아날로그/디지탈 변환수단과, 아날로그/디지탈 변환수단에 의해 디지탈형태로 변환된 제1트랙의 영상신호를 저장하는 메모리수단과, 메모리수단에 저장된제1트랙의 디지탈 영상신호를 아날로그 영상신호로 변환하는 디지탈/아날로그 변환수단과, 디지탈/아날로그 변환수단으로부터 인가된 제1트랙의 영상신호와 제1비데오 헤드로부터 인가된 제2트랙의 영상신호를 반복 교차되어 출력되도록 하는 제2스위칭수단, 및 제1 및 제2스위칭수단의 스위칭동작을 제어함과 동시에 메모리수단으로부터 저장된 데이타가 출력되는 것을 제어하는 제어수단을 구비하였다.The present invention relates to a high speed search apparatus of a video cassette recorder, comprising: switching a video signal of a first track detected by a second video head to provide clean image quality during a high speed search using a two-head video cassette recorder; 1 switching means, analog / digital converting means for converting the analog video signal of the first track applied through the first switching means into a digital video signal, and of the first track converted into a digital form by the analog / digital converting means. Memory means for storing the video signal, digital / analog converting means for converting the digital video signal of the first track stored in the memory means into an analog video signal, video signal of the first track applied from the digital / analog converting means, and Second switching means for repeatedly outputting the video signal of the second track applied from the first video head; Control means for controlling the switching operation of the first and second switching means and controlling the output of the stored data from the memory means.
