In the previous two chapters, we have seen that MPEG video compression is used for contribution and distribution (C&D) applications as well as for statistical multiplexing systems in DTH head-end systems. Today, it is inevitable that video signals undergo several stages of compression and decompression before it reaches the end user, and with the growth of digital television networks, concatenation of compression encoding and decoding is becoming more and more prevalent. In this chapter we will have a closer look at all combinations of concatenation between MPEG-2 and MPEG-4 (AVC).
