ITU-R BT.2077-3 PDF

This Recommendation defines Serial Digital Interfaces for UHDTV uncompressed signals with 7 680 × 4 320 and 3 840 × 2 160 pixel counts, various frame frequencies up to 120 Hz, 4:4:4, 4:2:2, and 4:2:0 sample structures, and 10 and 12 bit depths defined in Recommendations ITU-R BT.2020 and ITU-R BT.2100. This Recommendation is divided into four parts. Part 1 and Part 3 are based on 10-bit word containers and Part 2 is based on 12-bit word containers. Part 1 and Part 2 use multi-link 10 Gbit/s optical interfaces and Part 3 uses single link and multi-link 6 Gbit/s, 12 Gbit/s and 24 Gbit/s electrical and optical interfaces – Part 4 defines single fibre operation for 26.73 Gbit/s and 100 Gbit/s, while dual fibre 100 Gbit/s operation is also defined for frame rates greater than 60 Hz.
