Abstract
본 발명은 음향기기나 영상기기의 오디오신호를 제어함에 있어서, MPEG 디코더의 비트 스트림에서 에러가 발생되었을 경우 해당 프레임을 발생시켜 발생된 에러를 정정하기 위한 MPEG 디코더의 출력 버퍼장치에 관한 것으로, 저장된 프레임 신호를 디지탈 신호로 출력하는 프레임저장부(10)와, 상기 프레임저장부(10)에서 출력 되는 비트스트림을 디코딩하여 프레임신호의 주파수 영역에 대한 데이타를 발생시키는 데이타변환부(20)와, 상기 데이타변환부(20)에서 변환된 데이타를 필터링하는 필터(30)와, 상기 필터(30)에서 입력된 데이타를 이용하여 설정하고자 하는 동기신호를 맞추고 비트 스트림을 정정하는 출력버퍼(40)와, 상기 출력버퍼(40)에서 출력되는 디지탈 신호를 아날로그 신호로 변환하여 출력하는 D/A 변환부(50)가 구비된 MPEG디코더에 있어서, 상기 데이타변환부(20)에서 변환된 데이타가 에러발생시 각각의 메모리(61~63)에 저장된 데이타를 이용하여 프레임을 재생시켜 에러를 정정하여 필터(30)에 출력하는 메모리부(60)를 더 포함하여 MPEG 디코더의 비트스트림에서 에러가 발생되었을 경우 메모리부에 저장된 다수개의 데이타를 이용하여 해당 프레임을 발생시켜 발생된 에러를 신속하게 정정할 수 있는 것이다.The present invention relates to an output buffer device of an MPEG decoder for correcting an error caused by generating a corresponding frame when an error occurs in a bit stream of an MPEG decoder in controlling an audio signal of an audio device or a video device. A frame storage unit 10 for outputting a frame signal as a digital signal, a data converter 20 for decoding the bitstream output from the frame storage unit 10 and generating data for a frequency domain of the frame signal; A filter 30 for filtering the data converted by the data converter 20, an output buffer 40 for matching a synchronization signal to be set using the data input from the filter 30, and correcting a bit stream; In the MPEG decoder provided with a D / A converter 50 for converting the digital signal output from the output buffer 40 to an analog signal and outputs it, When the data converted by the data conversion unit 20 is an error occurs further includes a memory unit 60 for reproducing the frame by using the data stored in each of the memory (61 ~ 63) to correct the error and output to the filter 30 Therefore, when an error occurs in the bitstream of the MPEG decoder, a corresponding frame can be generated quickly by using a plurality of data stored in the memory unit.
