JPEG XS 3rd Edition: The New Temporal Differential Coding (TDC) Profile
The 3rd edition of JPEG XS introduces the Temporal Differential Coding (TDC) profile, further improving the compression efficiency over the XS High profile. TDC adds a wavelet-domain temporal prediction block using a single compressed frame buffer to reduce correlation between successive frames, especially in static regions, without requiring motion compensation or complex algorithms. It preserves JPEG XS's key features: lightweight, fast compression with low latency, near-lossless quality, and low complexity. Experiments indicate that TDC significantly improves detail preservation and edge sharpness, with Peak Signal-to-Noise Ratio (PSNR) gains exceeding 10 dB in graphics, e-sports, gaming, and desktop videos. And, for high-motion content, TDC maintains at least the same performance as XS High. Compatible across Central Processing Units (CPUs), Graphical Processing Units (GPUs), Field Programmable Gate Arrays (FP-GAs), and Application-Specific Integrated Circuits (ASICs), TDC offers a seamless upgrade for existing JPEG XS ecosystems. This paper details TDC's technical aspects and demonstrates its performance benefits, emphasizing that latency and complexity remain unaffected.
