“…Even more, if the high-pass frames are discarded, synthesis is performed purely based on the low-pass temporal frames and motion information. A very efficient codec using MCTF and an intra-band coding technique, called embedded zero block coding (EZBC), was proposed by Hsiang and Woods in [8]. This code is labeled Motion Compensated EZBC or (MC-EZBC) and has been the focus of different investigations [7].…”

We introduce an efficient and flexible framework for temporal filtering in wavelet-based scalable video codecs called unconstrained motion compensated temporal filtering (UMCTF). UMCTF allows for the use of different filters and temporal decomposition structures through a set of controlling parameters that may be easily modified during the coding process, at different granularities and levels. The proposed framework enables the adaptation of the coding process to the video content, network and end-device characteristics, allows for enhanced scalability, content-adaptivity and reduced delay, while improving the coding efficiency as compared to state-of-the-art motion-compensated wavelet video coders. Additionally, a mechanism for the control of the distortion variation in video coding based on UMCTF employing only the predict step is proposed. The control mechanism is formulated by expressing the distortion in an arbitrary decoded frame, at any temporal level in the pyramid, as a function of the distortions in the reference frames at the same temporal level. All the different scenarios proposed in the paper are experimentally validated through a coding scheme that incorporates advanced features (such as rate-distortion optimized variable block-size multihypothesis prediction and overlapped block motion compensation). Experiments are carried out to determine the relative efficiency of different UMCTF instantiations, as well as to compare against the current state-of-the-art in video coding. r

We propose a 4G system for transmission of video from a server at the base station to numerous wireless clients. We employ the latest technology in scalable video compression (3-D wavelet video coding) and in channel coding (punctured turbo codes); for the physical layer, we resort to the multicarrier chip-interleaved system with two-layer interleaving, which achieves high spectral efficiency and is very suitable for downlink applications. We develop fast algorithms for a cross-layer resource allocation that minimize the expected distortion of the reconstructed video averaged over all clients. The algorithms find a near-optimal power, bandwidth, and subcarrier allocation at the physical layer and a source-channel symbol allocation at the application layer. Our experimental results demonstrate that such a cross-layer optimization framework leads to higher quality performance of the overall system
