METHOD OF BUFFERING A PIXEL AND BUFFER SYSTEM

摘要

PURPOSE: A method of buffering a pixel and a buffer system of the same are provided to reduce calculation quantity which is consumed by referring a neighboring pixel. CONSTITUTION: A buffering control unit(17) controls a way which buffers a decoded macro block. A frame macro block buffer(15) stores the decoded macro block by frame unit according to the controlled buffering way. A motion compensation/intra prediction unit(12) performs motion compensation and intra predict by referring a value stored in the frame macro buffer about the decoded macro block. An inverse transform/de-quantization unit(13) performs reverse conversion/inverse quantization about the decoded macro block.
