Scalable video coder combined with multiplexed codes

摘要

Encoding video in scalable formats supports fast and efficient adaptation. Fully scalable video bit-stream requires layered structure of most of its components. However, layered representation requires new entropy coding strategies able to efficiently protecting different layers. In this work, we apply multiplexed codes on a scalable video coding (SVC) scheme with a spatial scalability as well as a temporal scalability. Experimental results reveal a very high error resilience at almost no cost in compression efficiency. Tests indicate that with multiplexed codes, it is possible to ensure auto_synchronisation decoder in the case of corrupt bit-stream, without increasing the bit rate or the complexity of treatment.
