Abstract

In this work we present an efficient video compression scheme which supports a fast bit rate adaptation independent of the encoder. The proposed scheme generates an embedded bitstream for each frame or, by appropriate multiplexing, for each group of picture. This rate-scalability is supported by an embedded bitstream which allows decoding at multiple rates, or to be more specific at virtually any rate. This video codec is successfully combined with an unequal erasure protection scheme to reduce the effects of packet losses. An optimized rate allocation scheme to trade-off source rate and redundancy is presented. Experimental results show the potential of the presented combination.
