Abstract
Compression efficiency and bitrate scalability are among the key factors in video coding. The paper introduces novel sub-sequence coding techniques for temporal scalability. The presented coding schemes provide a wider range for bitrate scaling than conventional temporal scalability methods and maintain high coding efficiency at the same time. The proposed sub-sequence techniques are adopted into the latest video coding standard, H.264, making it easy to identify sub-sequences and possible to discard them intentionally. As shown by extensive simulations, a wide range of applications, from mobile messaging to consumer electronics, such as digital TV, can benefit from sub-sequences.
