Abstract


In recent years , significantly speeding up the conversion of analog to digital television , herald a new digital TV era is approaching . Therefore, the study of digital TV technology more and more attention has been paid . Digital television signals using MPEG-2 codec standard , and thus the MPEG-2 decoder design has become a popular research direction . In this paper, for the MPEG- 2 standard algorithm , the overall study video decoder circuit design and implementation. In the text , the MPEG - 2 video decoding device of the system structure optimization design study of achieving decoder various sub- module structure and method , and on this basis, design and validation of some of the relevant sub- module circuit improvements of the new method . In this thesis the main work on the study of the MPEG-2 video decoding system as follows: 1 through research the MPEG- 2 video decoder system principle and characteristics of the structure , design an optimized decoder structure , support MPEG-2 standard MP @ ML stream. The decoding system structure using the Verilog hardware description language to describe and verify . 2 . Designed video stream demultiplexing can extract any set of program modules, and analysis to extract video stream video analysis module , which introduces a new variable-length code decoding circuit structure . Design a MPEG - 2 decoder suitable for anti- scanning and anti - the quantization circuit , proposed and implemented a new structure of an optimized IDCT circuit . 4 design suited to the MPEG-2 motion compensation module . Pixel cache unit modules in the module is designed to simplify the prediction unit in the half pixel prediction calculation and prediction efficiency can be improved .
