Practical video interfacing
Having covered a lot of theoretical ground and described the detail of a number of standards earlier in this book, the purpose of this chapter is to give practical advice in configuring, timing, testing and maintaining digital video interface systems. The techniques and tools needed to test digital interfaces are quite different to the traditional analog approach and will be described here. The great similarity between HD-SDI and SD-SDI means that the same installation and test principles apply. In practice the higher frequency of the HD signal means that the effect of a shortcoming will be more serious in HD.
