METHOD, SYSTEM AND APPARATUS FOR PARSING MULTILAYER DATA STREAM

摘要

The present invention provides a method, a system and an apparatus for parsing a multilayer data stream. According to the technical solution provided by the present invention, a scheduler allocates and initializes a pre-parser, a deep-parser and a shared memory; the pre- parser pre-parse a frame in the multilayer data stream into data slices and put the pre-parsing result to the shared memory; the deep-parser gets one of the data slices from the shared memory and deep-parse the data slice into data macro-blocks. The case will not exist that the latter frame is parsed before the former frame. It is also optimized as to the storage capacity requirement and complexity of data transmission. In addition, the variability of the number of the parser makes it possible to improve the use efficiency of the parsers while keeping the parsing speed.
