语音同步器

The first idea to deal with the packet loss is the new proposal of multitask ATM cells and the required new ADPCM encoder. This scheme combines three tasks together, namely, reducing cell packeting delay, avoiding breakdown of speech decoders due to one lost cell, compensating or replacing the lost information segment, by dividing the cell payload field into two parts——main and additional information fields, the latter again consists of synchronization information and the coded speech information contained in the last cell.

首先以ATM网络为例，提出了新的信息分组多任务装配法，以及对应此方法的新型ADPCM语音编码系统，这种方法中，利用特殊设计的编码器，使ATM信元负载信息域，由主要和附加用户信息两部分组成，后者又由同步信息和前一个信元语音段信息组成，通过选择和调节信元中两部分信息域的比例，实现了小的分组装配时延、高的分组丢失补偿质量、强的阻断误差传递功能三者的结合。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
