Adaptive M-band hierarchical filterbank for compliant temporal scalability in H.264 standard
The paper presents a solution of temporal scalability for video encoded H.264/MPEG-4 AVC bitstreams. Achieved through the concept of adaptive M-band hierarchical filterbanks, the temporal scalability is performed thanks to the application of a frame shuffling operation which allows backward compatibility with the standard to be kept. Simulation results show that this scalability is obtained with no degradation in terms of subjective and objective quality.
