Abstract

본 발명은 배속재생을 위한 가변비트율 디스크재생시스템에 관한것으로서, 디스크상의 소정 트렉에서 재생되는 RF 신호를복조하는 RF재생부; RF 재생부에서 복조되는 데이타를 해당하는 포맷에 맞게재생하여, 소정의 크기에 해당되는 데이타블럭이 준비되면 데이타준비신호를 출력하는 CD/SD 재생부; 바로 이전에 재생하였던 마지막 블럭 및 VBR 버퍼의 상태를 조사하여 CD/SD 재생부로부터 입력할 블럭의 크기를 인식한 후, 인식된 블럭의 시작번지 및 블럭크기에 대한 명령을 CD/SD재생부로 인가하고, 배속재생시 데이타 요구량이 CD/SD 재생부의 데이타 공급량보다 클 경우 VBR 버퍼에 저장된 데이타량에 따라 배속재생혹은 보통재생에 해당하는 속도로 절환하여 출력하는 가변전송부; 화면재생속도에 따라 가변전송부로 데이타 요구신호를 출력하며, 데이타 요구신호에 따라 가변전송부에서 출력되는 영상 혹은 음성신호를 디코딩하여 외부로출력하기 위한 AV 재생부; 및 픽업이 디스크상에서가변전송부에서 인식한 블럭이 들어있는 트랙으로 이동하도록 제어하는서보부로 구성된다. 따라서, 배속재생시 AV 재생부에서 요구하는 데이타양이 CD/SD 재생부에서 공급할 수 있는 데이타양보다 클 경우 배속재생 중에 발생하는 시청자가 감지가능한 정지화면을 시청자가감지불가능한 소화면으로 나누어 배속재생화면 중에 삽입함으로써 배속재생화면을 질을 획기적으로 높일 수 있다.The present invention relates to a variable bit rate disc reproduction system for double speed reproduction, comprising: an RF reproduction unit for demodulating an RF signal reproduced at a predetermined track on a disc; A CD / SD reproducing unit for reproducing the data demodulated by the RF reproducing unit according to a corresponding format and outputting a data preparation signal when a data block corresponding to a predetermined size is prepared; After checking the status of the last block played just before and the VBR buffer, the size of the block to be input from the CD / SD player is recognized, and the command for the start address and block size of the recognized block is applied to the CD / SD player. A variable transmission unit for switching at a speed corresponding to double speed playback or normal playback in accordance with the amount of data stored in the VBR buffer when the data demand amount during the double speed playback is larger than that of the CD / SD playback unit; An AV playback unit for outputting a data request signal to the variable transmission unit according to the screen reproduction speed, and decoding and outputting the video or audio signal output from the variable transmission unit according to the data request signal; And a servo unit for controlling the pickup to move to the track containing the block recognized by the variable transfer unit on the disc. Therefore, if the amount of data required by the AV playback unit is greater than the amount of data that can be supplied from the CD / SD playback unit during double speed playback, the user can detect the still picture that can be detected during double speed playback by dividing it into small pictures that the viewer cannot detect. By inserting it into the screen, the playback speed of the double speed playback screen can be dramatically improved.

Claims (2)

디스크상의 소정 트랙에서 재생되는 RF 신호를 복조하기 위한 RF 재생부, 상기 RF 재생부에서 복조되는 데이타를 해당하는 포맷에 맞게 재생하여, 소정의 크기에 해당되는 데이타블럭이 준비되면 데이타 준비신호를 출력하기 위한 CD/SD 재생부, 바로 이전에 재생하였던 마지막 블럭 및 VBR 버퍼의 상태를 조사하여 상기 CD/SD 재생부로부터 입력할 블럭의 크기를 인식한 후, 인식된 블럭의 시작번지 및 블럭크기에 대한 명령을 상기 CD/SD 재생부로 인가하고., 배속재생시 데이타 요구량이 상기 CD/SD 재생부의 데이타 공급량보다 클 경우 상기 VBR 버퍼에 저장된 데이타량에 따라 배속재생혹은 보통재생에 해당하는 속도로 절환하여 출력하는 가변전송부, 화면재생속도에 따라 상기 가변전송부로 데이타 요구신호를 출력하며, 상기 데이타 요구신호에 따라 상기 가변전송부에서 출력되는 영상 혹은 음성신호를 디코딩하여 외부로 출력하기 위한 AV 재생부; 및 픽업이 디스크상에서 상기 가변전송부에서 인식한 블럭이 들어있는 트랙으로 이동하도록 제어하는 서보부를 포함하는 것을 특징으로 하는 배속재생을 위한 디스크 가변전송 재생시스템.An RF reproducing unit for demodulating an RF signal reproduced on a predetermined track on a disc, and reproducing the data demodulated by the RF reproducing unit according to a corresponding format, and outputting a data preparation signal when a data block corresponding to a predetermined size is prepared. The size of the block to be input from the CD / SD playback unit by checking the state of the CD / SD playback unit, the last block played just before, and the VBR buffer, and then the start address and block size of the recognized block. Command to the CD / SD playback unit, and if the data demand during the double speed playback is greater than the data supply of the CD / SD playback unit, the speed is switched to the speed corresponding to the double speed playback or normal playback according to the amount of data stored in the VBR buffer. A variable transmission unit for outputting a data request signal to the variable transmission unit according to the screen reproduction speed, and according to the data request signal. AV playback unit for decoding the video or audio signal outputted from the substation to transmit the output to the outside; And a servo unit for controlling pickup to move on a disc to a track containing a block recognized by the variable transfer unit. 제1항에 있어서, 상기 가변전송부는 상기 VBR 버퍼에 단위버퍼하한선 및 단위버퍼상한선을 설정하고, 배속재생명령을 수행하다가 상기 AV 재생부의 데이타 요구신호에 따라 출력되는 데이타가 단위버퍼하한선에 이르면 소비된 상기 VBR 버퍼의 데이타를 충당하기 위하여 소정 시간동안 보통재생명령으로 전환하고, 보충되는 데이타가 다시 단위버퍼상안선에 이르면 다시 배속재생명령으로 전환하여 단위버퍼하한선까지 데이타를 출력하는 것을 특징으로 하는 배속재생을위한 디스크 가변전송 재생시스템.The apparatus of claim 1, wherein the variable transfer unit sets a unit buffer lower limit and a unit buffer upper limit in the VBR buffer, executes a double speed playback command, and consumes when data output according to the data request signal of the AV playback unit reaches a unit buffer lower limit.
