The UHD World Association has published standard T/UWA 012.1-2023, which mandates the use of JPEG XS compression and MXF OP1a packaging for 8K UHD broadcasting. This standard establishes formal technical requirements for the 'Bai Cheng Qian Ping' public broadcasting initiative in China.
This formal adoption of JPEG XS for 8K delivery marks a transition away from traditional inter-frame codecs like XAVC-I when handling massive UHD data rates. By mandating a visually lossless, low-complexity codec, the UHD World Association is prioritizing multi-generation signal integrity and low-latency playout for large-scale public infrastructure. This move reinforces JPEG XS as the primary mezzanine format for high-resolution IP workflows, bridging the gap between raw capture and final distribution. As 8K production scales globally, watch for other regional standards bodies to adopt similar intra-frame requirements to manage the processing loads of 7680x4320 resolutions without sacrificing quality.
The industry is seeing a broader trend of broadcasters urge FCC to maintain flexibility in technical transitions as new standards emerge.
The UHD World Association has established technical specification T/UWA 012.1-2023, mandating JPEG XS for 8K broadcasting in China. This standard requires visually lossless compression and MXF OP1a packaging to support the 'Bai Cheng Qian Ping' public display initiative, ensuring high-quality, low-latency signal integrity for large-scale 8K infrastructure across more than 100 cities.
The new standard is T/UWA 012.1-2023, which mandates the use of JPEG XS High 444 12 Profile for all 8K UHD program files.
Files must utilize MXF OP1a packaging that is compliant with SMPTE ST 377-2 and ST 379-2 standards to ensure integration into existing broadcast workflows.
The 8K requirement mandates an intra-frame bitrate of approximately 2073.6 Mbps.
The association adopted JPEG XS to prioritize multi-generation signal integrity and low-latency playout, moving away from traditional inter-frame codecs to better handle massive UHD data rates.
