Prescient R-D optimized packet dependency management for low-latency video streaming
We present an improved, prescient, scheme to deliver pre-encoded video streams at very low latency. We dynamically manage the prediction dependency for a group of packets using a ...

Super resolution of video using key frames
— In many video compression systems, the frames are down-sampled before transmission. Also, in many scalable systems, the residual after down- and up-sampling is encoded and tran...

Macroblock-level Reduced Resolution Video Coding Allowing Adaptive DCT Coefficients Selection
—Reduced Resolution Update (RRU) video coding provides a better compression performance than H.264/AVC does. It is implemented by encoding the predicted residuals after downsampl...
