Abstract: This paper presents the design of a fine granularity SNR scalable video coder for low-delay applications. Specifically, temporal prediction is introduced into the FGS layer of closed-loop P-frames. The prediction is formed adaptively from the enhancement layer reference and the base layer reference, utilizing information coded in the base layer. This novel FGS coder can control drift that may occur due to partial decoding of the FGS layer, while at the same time achieving high coding efficiency. Effort is also spent on reducing the complexity of the new solution by using low-complexity motion compensation and by minimizing additional transform operations. With minimal increase in the complexity, the FGS coding performance of closed-loop P-frames can be improved by as much as 4.5 dB for one FGS layer on a base layer coded at QP 42.
