另外,作者对RTP模块的功能也进行了扩展与完善,包括:传输DTMF事件和静音压缩包。
Besides, I also expand and perfect the RTP module, including transmits DTMF event and sid.
这些算法应用于语音中的静音期间以进一步降低传输速率和提高信道利用率,是为G.729研究的最佳静音压缩方案。
These algorithms are used during silence periods of speech to reduce ratio of transmission and improve ratio of use in signal channel. It's a best silence compression scheme for G. 729.
以此类推tp552就是指有2个55 0瓦压缩机头的静音无油空压机。
By analogy TP552 is to point to have two 550 watts of compressed with quiet oil free compressor.
