ABSTRACT:
An encoded bitstream is generated for playback scalability in terms of both bitrate scalability and decode scalability. During encoding, at least one component plane of each video frame is transformed into two or more bands of data. Each band is then encoded independent of the other bands and the resulting encoded bands are embedded in an encoded bitstream. At least one band sequence is encoded using interframe encoding.
