Video coding with flexible MCTF structures for low end-to-end delay

Some of the most powerful schemes for scalable video coding are based on the so-called (t + 2D) paradigm and provide coding performance competitive with state-of-the-art codecs. However, the temporal multiresolution schemes used in such codecs introduce a non-negligible delay, preventing their use in applications which require low latency, like video conferencing or video streaming. In this paper, we provide a flexible approach to reduce the end-to-end delay involved in motion-compensated temporal filtering schemes. We show by simulations results the trade-offs observed between coding efficiency and low end-to-end delay.
