The proliferation of low-cost DRAM chipsets now begins to allow for the consideration substantially-increased decoded picture buffers in advanced video coding standards such as HEVC, VVC, and Google VP9. At same time, increasing demand rapid scene changes multiple repetitions entertainment or broadcast content indicates that extending frame referencing interval tens minutes even entire sequence...

In this paper, we introduce a highly scalable video compression system for very low bit-rate videoconferencing and telephony applications around 10–30 Kbits/s. The video codec first performs a motion-compensated three-dimensional (3-D) wavelet (packet) decomposition of a group of video frames, and then encodes the important wavelet coefficients using a new data structure called tri-zerotrees (T...
