[M4IF Technotes] FGS and frequencies

[Roland Bengtsson]

Is it correct to say that the baselayer on FGS contain the lowest 
frequencies in a frame and the enhancement layer contain higher frequencies 
in bitplanes? The highest bitplane contain the highest frequency and will 
be removed first if a degration of quality is done.
Is FGS in MPEG-4 the same as signal-to-noise scalability?
I would be thankful if someone would clarify this for me.
Regards Roland
