Error resilient, low latency video coding for interactive video applications requires progressive intra coding of macroblocks (MBs) to contain the error propagation. Both refresh MB selection (RMS) and refresh rate selection (RRS) impact the subjective video quality in the presence of packet losses. Joint source-channel rate distortion optimization methods attempt to find the best trade-off between...
Low bit-rate live encoding and streaming of video over wired or wireless channels, as utilized in place-shifting applications, need to adapt the frame rate and bit-rate according to content and channel conditions. Typical rate control schemes work with a given target frame rate and can result in irregular frame skips that are induced by buffer conditions and quantizer saturation. Prior methods proposed...
Motion compensated prediction of video results in decoder-side error propagation (EP) in the presence of channel losses. Progressive intra-refresh methods control the EP, but lead to a drop in coding efficiency (CE). Error-resilient video coding schemes using multiple reference frames have been proposed earlier to achieve a better CE. Some schemes (e.g. ACK-based) tend to be conservative at the expense...
