Summary :

This paper describes a design method of stuff synchronization circuit for High-definition Television (HDTV) transmission to reduce stuff jitter, one of the greatest problems in video transmission through plural Synchronous Digital Hierarchy (SDH) networks operating with different frequency sources. First, we determine the quantity of stuff jitter in SDH networks using the pointer mechanism and Administration Unit (AU) pointer bytes. From the results of a subjective test conducted for HDTV, we show that the minimum noticeable jitter is 3.6 nsec in using a color-bar pattern as a test image and a sinusoidal wave as a jitter signal. These results are used to describe the effect of stuff jitter on picture quality. We then introduce a distributed destuffing method at the receiving end, and show that jitter can be reduced by about 32dB in a 622Mbps rate system. Based on these results, we finally show that the cut-off frequency of the clock recovery PLL for distributed destuffing is more than 10 times higher than that required by conventional destuffing. This reduces the pull-in time by more than 99.9%.
