Source Coding

In earlier chapters we discussed the rich media multiplex. How do we capture the
properties of wideband audio, image, and video and preserve the properties of the rich
media mix as we move across the radio layer—into and through the network? Source
coding is arguably the single most important process to address when we look at capturing
and preserving complex content value. It effectively dictates how we dimension
and prioritize our radio layer and network layer resources. In particular in this chapter
we want to review how the evolution of MPEG-4 will influence future handset software
functionality.
