Abstract

채널 변경이나 초기 전원 온시 방송 수신신호가 디스플레이될 동안 사용자가 지루하지 않고 보다 편지하게 시청하기 위한 디지탈 영상 복호화 시스템의 초기 화면 발생회로가 개시된다.An initial screen generating circuit of a digital image decoding system is disclosed for a user to watch a letter more steadily without being bored while displaying a broadcast reception signal when a channel change or initial power-on is displayed.

이러한 초기 화면 발생회로는 압축 부호화된 디지탈 영상데이타를 수신하여 다시원래의 영상 데이타로 복원하기 위해 복호화 하는 영상 복호기와, 상기 복호화된 영상 데이타를 저장하는 주화면 저장부를 포함하는 디지탈 영상 복호화 시스템의 초기 화면 발생회로에 있어서, 상기 이미 복호화된 영상 데이타를 저장한 소정의 영상 데이타를 저장하고, 최초 세트 제조시에 초기 화면을 등폭 및 저장하는 수단과 ; 상기 주화면 저장부에서 출력되는 주화면 영상 데이타 또는 상기 초기 화면 등록 및 저장 수단에서 제공되는 보조 초기 화면의 영상 데이타를 선택하여 출력하는 주화면 및 보조 초기 화면 선택 회로와 ; 상기 주면 및 보조 초기 화면 들중 하나를 선택하도록 상기 주화면 및 보조 초기 화면 선택회로로 소정의 제어신호를 제공하는 화면 선택 로직부를 포함한다.The initial screen generation circuit includes an image decoder which decodes and receives the compressed coded digital image data and restores the original image data. The initial screen generation circuit includes an initial image storage system for storing the decoded image data. A screen generating circuit, comprising: means for storing predetermined video data storing the already decoded video data, and equalizing and storing an initial screen at the time of manufacture of the first set; A main screen and an auxiliary initial screen selection circuit for selecting and outputting main screen image data output from the main screen storage unit or image data of an auxiliary initial screen provided by the initial screen registration and storage means; And a screen selection logic unit configured to provide a predetermined control signal to the main screen and the auxiliary initial screen selection circuit to select one of the main surface and the auxiliary initial screens.
