Abstract
비디오 스트림을 저장하기 위한 버퍼가 오버플로윙 및/또는 언더플로웡하는 것을 방지할 수 있는 MPEG비디오 디코더가 기술된다. 비디오 디코딩 장치는 디코드된 픽처를 생성하기 위해 일련의 픽처를 포함하는 코드된 비디오 비트 스트림을 디코드한다. 비디오 디코딩 장치는 비디오 비트 스트림을 일시적으로 저장하기 위한 비트 버퍼; 디코드된 픽처를 생성하기 위해 비트 버퍼로부터 출력된 비디오 비트 스트링을 수신하고 비디오 비트 스트림을 디코딩하기 위한 디코딩 회로, 및 비트 버퍼내에 저장된 비디오 비트 스트림의 데이타량에 기초하여 비트 버퍼로부터 디코딩 회로에 공급될 비디오 비트 스트림의 양을 제어하기 위한 비디오 비트 스트림 제어 회로를 포함한다.An MPEG video decoder is described that can prevent the buffer for storing the video stream from overflowing and / or underflowing. The video decoding apparatus decodes a coded video bit stream comprising a series of pictures to produce a decoded picture. The video decoding apparatus includes a bit buffer for temporarily storing a video bit stream; A decoding circuit for receiving a video bit string output from the bit buffer to generate a decoded picture and decoding the video bit stream, and to be supplied from the bit buffer to the decoding circuit based on the data amount of the video bit stream stored in the bit buffer. Video bit stream control circuitry for controlling the amount of video bit stream.
