Distortion Control for Queues with Deadlines
We investigate the optimum transmission strategy that minimizes the overall distortion for delaysensitive but distortion-tolerant data. We consider a set of source symbols residin...

An improved distortion model for rate control of DCT-based video coding
This paper presents a rate control algorithm for the dominant discrete cosine transform (DCT) -based video coding. It is developed based on a more accurate rate-distortion (RD) mo...

Rate-Distortion Optimized Slicing, Packetization and Coding for Error Resilient Video Transmission
This paper presents an algorithm to optimize the tradeoff between rate and expected end-to-end distortion of a video sequence transmitted over a packet network. The approach optim...
