In this thesis, an all-digital phase-locked loop with large multiplication factor is presented. This circuit can be applied to the video system as a clock generator. It receives the horizontal synchronous signal from the graphics card and then generates a high frequency pixel clock according to the monitor resolution setting to acquire the video signal data. The stability of this sampling clock affects the display image quality directly. If the pixel clock is not stable, the display image will be glittering or jittering.

在本论文中，我们提出一个高频率倍数的全数位式锁相回路，此电路可应用於视讯系统中的时脉产生器，其主要功能是接收显示卡发出的水平同步讯号，并依据使用者设定的萤幕解析度，产生高频像素时脉来撷取视讯讯号资料，取样点的稳定度直接影响到显示画面的品质，若是像素时脉不稳定，则显示画面会闪烁或抖动。

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。
