Abstract

본 발명은 디지탈 영상 디스크 플레이어(Digital Video Disc Player;DVDP)의 동작을 테스트하는 장치에 관한 것이다. 본 발명은 디인터리빙부와 에러정정부의 출력단에 멀티플렉서를 구비하여 에러정정여부에 따라 선택적으로 데이타를 출력한다. 따라서, 본 발명은 에러정정을 실시했을 때와 실시하지 않았을 때를 쉽게 구별할 수 있어 효율적인 테스트를 가능하게 하는 효과를 갖는다.The present invention relates to an apparatus for testing the operation of a digital video disc player (DVDP). The present invention includes a multiplexer at the output terminal of the deinterleaving unit and the error correction unit, and selectively outputs data according to the error correction unit. Therefore, the present invention can easily distinguish between when the error correction is performed and when it is not, and thus has the effect of enabling an efficient test.

Description

디지탈 영상 디스크 플레이어 (DVDP)의 동작테스트장치Motion Tester of Digital Video Disc Player (DVDP)

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 의한 디지탈 영상 디스크 플레이어(DVDP)의 동작테스트장치를 나타낸 구성도.2 is a block diagram showing an operation test apparatus for a digital video disc player (DVDP) according to the present invention.

Claims (1)

에러정정코드가 부가된 후 인터리빙(interleaving)되어 디스크에 기록된 디지탈 데이타를 독출하여 재생하는 시스템의 동작을 테스트하는 장치에 있어서, 상기 디스크로부터 독출하여 복조한 디지탈 데이타를 인가받아 디스크에 기록되기 이전의 순서로 정렬하는 디인터리빙부; 상기 정렬된 데이타를 인가받아 에러가 있을 경우 이를 정정하는 에러 정정부; 상기 디인터리빙부와 에러정정부로부터 출력되는 데이타를 인가받아 이중 하나를 선택적으로 출력하는 멀티플렉서; 및 상기 에러정정부를 동작시키는 신호를 입력할 때 상기 에러정정부로부터 인가받는 에러가 정정된 데이타를 출력하도록 제어하고, 상기 에러정정부의 동작을 중단시키는 신호를 입력할 때 상기 디인터리빙부로부터 인가받는 에러가 정정되지 않은 데이타를 출력하도록 상기 에러정정부와 멀티플렉서의 동작을 동시에 제어하는 제어입력부를 포함하는 디지탈 영상 디스크 플레이어(DVDP)의 동작테스트장치.An apparatus for testing the operation of a system interleaving after an error correction code is added to read and reproduce digital data recorded on a disc, wherein the digital data read and demodulated from the disc is received before being recorded on the disc. A deinterleaving unit arranged in the order of the order; An error correction unit that receives the sorted data and corrects an error if there is an error; A multiplexer for selectively outputting one of the data received from the deinterleaving unit and the error correction unit; And outputting data corrected by an error authorized by the error correction unit when inputting a signal for operating the error correction unit, and inputting a signal for stopping the operation of the error correction unit from the deinterleaving unit. And a control input unit for simultaneously controlling the operation of the error correction unit and the multiplexer so as to output data for which an authorized error is not corrected. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
