Abstract :
In this paper, the autocorrelation-based frame lossless recompression algorithm (AFLR) is proposed. The AFLR can save the memory bandwidth of video coding systems and preserves the visual-quality. The AFLR consists of two core techniques: (1) Correlation-based prediction technique, (2) Correlation-adaptive Golomb-Rice code. Furthermore, the relative block-based memory addressing (RBMA) is also proposed to provide AFLR with memory random access. The experiment result reveals that the memory bandwidth can be saved up to 38% on average.
