[M4IF Technotes] FGS

[Rob Koenen]

FGS is Fine Grain Scalability. There are many applications, including
delivery of pre-encoded content over networks where the bandwidth is 
unknown a-priori (e.g., IP) and/or can vary in real-time (e.g., mobile).
Another application is statistical multiplexing of pre-eoncoded 
programs for broadcast applications.
FGS adds layers of quality to a base layer, 11 in the case of MPEG-4,
so you can do smooth transitions between different qualities and
bitrates.
In MPEG-4 Audio, it is even possible to add 1 kbit/s layers. 
More information is in the MPEG-4 Overview,
