An Algorithm for Intra-Frame Video Coding Based on Continuous-Valued Syndromes

In current video compression systems the encoder performs computationally demanding predictive coding to exploit temporal correlation between successive frames. In this paper we present a video coder based on the principles of distributed source coding. Each frame is partitioned into blocks which are then transformed into the DCT domain. After introducing the concept of syndrome-based coding in a continuous domain, we simply use continuous-valued syndromes to represent the DCT coefficients that are expected to be highly correlated with side information created at the decoder. The proposed video coder offers an efficient, low-complexity, error-resilient encoding solution which reuses most of the building blocks of standard DCT-based intra-frame video coding.
