  1. An error detecting method which can prevent the decoding error affecting the next video packet head is used, and a restoration measure for b frame based on the mv prediction which can improve the visual quality has been studied. 3. a novel marking algorithm for ip diffserv based on the transmission condition and the different importance of video streams for decoder has been introduced

    2實現了mpeg - 4的差錯檢測、可逆變長解碼rvld和差錯掩蓋方法:對i或p幀紋理區的差錯先用rvld進行解碼，然後對殘留的差錯用空間插值或運動補償方法進行掩蓋，而對p幀的運動矢量mv ，利用圖像的空間平滑特性進行恢復; 3針對b幀差錯的復原，我們還提出了一種基於運動估計的方法。
  2. The first scheduling algorithm used in unbuffered crossbar supporting variable length packet is ip - pim which is based on voq. when a matching of a head - of - packet cell is made, this matching is maintained until all cells of that packet have been transferred

    本文首先研究了不帶緩存的crossbar中的變長調度演算法，這些調度演算法都是在定長調度演算法的基礎上發展而來。基本的思想都是保持一個完整的數據包傳送完畢，再改變該通道交叉開關的狀態。
