Abstract
본 발명은 엠팩-2의 레이트 및 버퍼 제어방법에서의 수식의 구조를 개선시켜 양자화 파라메타(QP)를 보다 효과적으로 적용할 수 있도록 엠팩-2의 레이트 및 버퍼 제어장치에 관한 것으로, 이를 해결하기 위하여 영상신호의 프레임을 DCT와 양자화기 및 VLC에 의거하여 부호화하여 부호화된 신호가 버퍼를 통해 출력되며, 상기 부호화된 프레임을 복호화하여 복원된 영상신호의 프레임을 이전 프레임으로 제공함과 아울러 움직임을 예측하며, 이전 영샹에 이용된 비트량과 이전 영상의 부호화된 양자화 파라메타에 의한 타켓 비트를 할당하는 타켓 계산부(5)를 포함하는 부호화 장치에 있어서; 버퍼의 충만상태와 상기 타켓 계산부의 타켓 데이터에 의거하여 양자화 파라메타를 계산하는 양자화계수 계산부(20); 입력되는 영상신호의 프레임에 대한 복잡도를 계산하는 복잡도 계산부(10)와; 상기 복잡도 계산부(10)로부터 제공되는 복잡도 데이터와 상기 양자화 계수 계산부(20)로부터 제공되는 양자화 파라메타를 근거로 하여 얻어지는 양자화 파라메타로서 양자화기를 제어하는 제 1 파라메타 계산부(30)로 구성으로써 부호 화시에 행하는 양자화를 보다 효과적으로 양자화할 수 있고, 구조를 개선에 따른 비용 감축 효과가 있다.The present invention relates to an apparatus for controlling the rate and buffer of MP-2 to improve the structure of equations in the MPEG-2 rate and buffer control method so that the quantization parameter (QP) can be applied more effectively. The encoded signal is encoded through the DCT, the quantizer, and the VLC, and the encoded signal is output through the buffer. A coding apparatus including a target calculating unit (5) for allocating target bits based on the amount of bits used in a previous picture and the coded quantization parameter of a previous picture; A quantization coefficient calculator 20 for calculating a quantization parameter based on a buffer full state and target data of the target calculator; A complexity calculator 10 for calculating a complexity of a frame of an input video signal; As a quantization parameter obtained based on the complexity data provided from the complexity calculator 10 and the quantization parameter provided from the quantization coefficient calculator 20, the first parameter calculator 30 controls the quantizer. The quantization performed at the time of painting can be quantized more effectively, and the cost reduction effect by the improvement of the structure is provided.
