H.264熵解码器的研究与实现
Research and Implementation of H.264 Entropy Decoder
摘要
Abstract
The context-based adaptive variable length entropy decoding quoted in H.264/AVC video coding standard can greatly reduce data redundancy and improve the decoding efficiency, meanwhile the complexity of Context-based Adaptive Variable Length Coding(CAVLC) decoding . Is increased. In this paper, a rapid and effective new entropy decoder which is based on entropy decoding algorithm is proposed. The decoder realizes entropy decoding to video compression streaming. In this process, parallel processing way is imported, and binary tree method is improved. Waveform simulations for the proposed decoder in Quartus II 7.2 and hardware implementation using FPGA prove the correctness of the design for proposed entropy decoder, besides, the proposed decoder has better performance in savings in hardware resources and decoding speed.关键词
