Video Compression with Intra/Inter Mode Switching and a Dual Frame Buffer
Video codecs that use motion compensation have recently achieved performance improvements from the use of intra/inter mode switching decisions within a ratedistortion framework. A...

Optimal Alphabet Partitioning for Semi-Adaptive Coding of Sources of Unknown Sparse Distributions
Practical applications that employ entropy coding for large alphabets often partition the alphabet set into two or more layers and encode each symbol by using some suitable prefix...

Rate-distortion Optimized Packet Scheduling and Routing for Media Streaming with Path Diversity
We consider diversity for media streaming in a rate-distortion optimization framework. A sender-driven transmission scenario is investigated, where diversity is achieved by using ...

An Error-Resilient Blocksorting Compression Algorithm
A Burrows-Wheeler Compressor breaks input into blocks, quickly makes each more compressible, and compresses the modified block with a simple arithmetic or Huffman compressor. We p...
