本論文主要目的在於研究數位視訊廣播系統中對 MPEG-2
Transport Stream 的各種特性. 所提出的演算法有兩個目的, 在
第一個部份是要讓所有的頻道的負擔能夠盡量平均. 而在第二個部份則是
經由緩衝器將 Transport Stream 的尖峰分開以提高頻道的使用率.
此外, 我們亦提出一個選擇延遲流 (delay stream) 績效評估標準.
實驗的結果顯示, 我們的演算法可以提高頻道中頻寬的使用率, 並且能夠
平均頻道的負載, 充份顯示了足夠的潛在可使用性.

The thesis is dedicated to the study of an algorithm for
MPEG-2 transport stream multiplexing in digital video
broadcasting systems, which isa branch of network traffic
improvement. The MPEG-2 transport stream characterizations for
digital video broadcasting systems are presented. In the
algorithm part I, we show that the channels can be
loadedbalance. And in the part II, we show that we can use the
delay buffer toprevent the channel overloading from dividing the
transport stream peaks. Furthermore, a new delay stream
evaluation criterion is proposed. Thehigh volume, low sensitive
is popular to be delayed. Experimental results show that
the new algorithm for transport stream multiplexing are
potential for use.
