Method for memory requirement reduction in a video decoder

摘要

The RAM requisite for temporarily storing a stream of digital data blocks in a coding/decoding system of information transferable by blocks may be significantly reduced by compressing and coding the data by blocks through a tree search vector quantization (TSVQ), storing TSVQ compressed and coded data in the RAM and decoding and decompressing during the subsequent reading of the data stored in the RAM thus reconstituting the stream of digital data blocks. <IMAGE>
