Hybrid low bitrate audio coding using adaptive gain shape vector quantization
—Audio coding at low bitrates typically suffers from artifacts caused by bandwidth truncation. In this paper we present a novel scheme to code audio signals at low bitrates which...

Redundant motion vectors for improved error resilience in H.264/AVC coded video
This proposal presents a new error robust strategy for encoding redundant pictures for the H.264/AVC standard. The method is based on providing motion vectors as redundant data, i...
