MPEG2音频压缩及编码的硬件实现方案

The Scheme of MPEG2 Voice-Frequency Compress and EncodeImplemented by Hardware

介绍了MPEG2标准的分层选择原则、音频压缩及编码过程;分析了MPEG2音频增强功能;提出了在芯片上实现MPEG2音频编码的解决方案。

ln this paper,the compresslayering selection principle,the process of voicefrequency compress and encode based on MPEG2 standard is introduced briefly. The strengthen functions of voicefrequency are discussed in detail.The solution to MPEG2 Voicefrequency code using a single chip is presented.
