As HD and UHD video content continues to grow, streaming over mobile networks faces significant quality challenges. To improve the delivery of compressed video, it’s crucial to enhance the compression of the coded video bit stream without losing information—known as lossless recompression.
We introduce a novel lossless recompression technique designed to address statistical redundancy in the coded video bit stream. This approach enhances the probability of continuous "0" or "1" sequences by rearranging the binary symbol sequence through value mapping and position aggregation. Specifically, our method employs a Fibonacci-based mapping rule to convert the original sequence into one with more extended runs of "0" or "1." We also aggregate identical symbols to further amplify repetitive patterns.
Our algorithm and asymptotic lossless compression scheme produce a compact representation of the reorganized symbol sequence, with formal syntactic structures ensuring a deterministic return to the original bit stream. Experiments with compressed H.264/AVC and H.265/HEVC video data demonstrate that our approach significantly reduces streaming video bit rates.
Oneall Streaming leverages this advanced lossless recompression technique to achieve efficient and high-quality video streaming.
