HEADER AND EXPANSION CODE RECURRENCER WITH MPEG-2

摘要

1. Technical field to which the invention described in the claims belongs;Header and extension code generator that conforms to the MPEG-2 syntax.;2. The technical problem to be solved by the invention;It aims to minimize the number of bits of input data by generating headers and extension codes for each split screen of high definition TV (HDTV) as well as standard TV (SDTV), and sequentially inputting a large amount of data necessary for encoding using a memory.;3. Summary of Solution to Invention;PES sequence caption head processing unit which generates PES header, caption data and other headers and extension codes, and outputs encoded data, effective length, valid time interval and motion vector code, and receives macroblock quant and IBP mode from outside And a slice head processor for generating a header, an effective length, and a valid time interval signal, and means for multiplexing the output of the PES sequence caption head processor and the output of the slice head processor.;4. Important uses of the invention;Used for variable length encoders.
