Same picture order count (POC) numbering for scalability support

Abstract:

Techniques are described for video encoding and decoding with same picture or count numbering for scalability support. One example involves obtaining a portion of a picture (e.g., a slice, a block, or other portion) and determining if weighted prediction is enabled for the portion of the picture. When weighted prediction is enabled, a zero value picture order count offset indicating a reference picture from a reference picture can be used, though different portion of the picture (e.g., different slices of a picture) can have different picture order count offset values. The portion of the picture can then be reconstructed using the reference picture identified by the zero value picture order count offset. Additional embodiments can use weighted prediction flags and different offset value determinations to support scalability or reference pictures in weighted prediction with a different size than the picture being reconstructed.
