[M4IF Technotes] Core Scalable Profile

[Santosh Chapaneri]

Hi,
I am doing a implementation of Core Scalable Profile for Mpeg4 Video Encoder.
I have the following doubts:
What is the difference between P-VOP based Temporal Scalability which supports Rectangular and Arbitrary shaped VOPs, and Temporal Scalability (Rectangular) ?
For Object Based Spatial Scalability, spatial scalable shape coding uses Scan Interleaving Algorithm. But the standard does not clearly indicate how to use the algorithm. For example, it says that for Intra mode CAE, first V-SI and H-SI both should be performed before doing CAE. Can anyone explain what is Scan Interleaving Algorithm?
Many Thanks for the timely help.
Thanks and Regards,
