编码解码器

短语

1
文中提出应用数字信号处理器和微控制处理器ARM9核的MPEG-4视频简易框架和高级音频编码解码器的实时嵌入式设计。
A real-time embedded design of MPEG-4 visual simple profile and advanced audio coding decoder using Digital Signal Processor and ARM9 core are presented in this paper.
2
为了压缩数据，LZ 77算法使用对匹配数据的引用来取代数据部分。匹配数据已经通过编码器和解码器传递。
To compress data, the LZ77 algorithm replaces portions of the data with references to matching data that has already passed through both the encoder and the decoder.
3
只要预测到符号是独特的，就不需要对其进行编码，因为解码器从DTD生成相同的模型，从而可以生成独特的预期符号。
Whenever the predicted symbol is unique, there is no need to encode it as the decoder generates the same model from the DTD and thus can generate the unique expected symbol.
