Abstract
A method for reducing the RAM requirement for temporarily storing a stream of data blocks in a coding/decoding system of information transferable by blocks, includes the steps of: 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 in a subsequent reading of the data stored in the RAM the coded and compressed data, thereby reconstituting the stream of digital data blocks. The method may include fixing a certain scanning path of each data block of the stream to be decomposed into vectors of preestablished dimensions; coding the first vector of the scanning of a certain block of data in an unmodified manner; generating a replica vector of the last coded vector and calculating a prediction error vector; quantizing according to a binary search in a table of read-only quantized vectors the prediction error, by coding its address in the table; and repeating several of the steps for all the vectors of the scanning of each input data block.
