90 4 Progressive Fine Granularity Scalable (PFGS) Coding
4.8 Summary
In this chapter, a highly efficient scalable video-coding framework is first presented.
Compared with the FGS scheme in MPEG-4, the PFGS framework tries to use some
higher quality references to improve the coding efficiency, since higher quality refer-
ences make motion predictions more accurate. In order to keep the scalability prop-
erties, such as fine granularity scalability, bandwidth adaptation, and error recovery,
the basic PFGS framework preserves a complete prediction path from the lowest
layer to the highest layer. However, multiple extra picture buffers are needed to save
the reconstructed reference layers in the basic PFGS framework, which increases the
memory cost ...
