Abstract :
The general problem of optimized video encoding has received a great deal of attention in recent years. This paper focuses on the optimization of video coding with frameskip. We propose models that estimate the distortion for coded frames as well as non-coded frames. Using these models in conjunction with well-know models that estimate the rate allows us to formulate a rate control problem that trades-off spatial and temporal quality. Simulation results indicate moderate improvements for low motion test sequences
