发明名称 Method and apparatus for memory efficient compressed domain video processing
摘要 A method for reducing the memory requirements for decoding a bit stream is provided. The method initiates with receiving a video bit stream. Then, a frame of the bit stream is decoded into a discrete cosine transform (DCT) domain representation. Next, non-zero coefficients of the DCT domain representation are identified. Then, a hybrid data structure is assembled. The hybrid data structure includes a fixed size array and a variable size overflow vector. Next, the non-zero coefficients of the DCT domain representation are inserted into the hybrid data structure. A computer readable media, a printed circuit board and a device configured to decode video data are also provided.
