9、in Recommendation ITU-R BT.2020. This Recommendation is divided into three 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
10、 Gbit/s and 24 Gbit/s electrical and optical interfaces. Keywords Serial Interface, UHDTV, Optical Interface, Sub-Image, Real-Time The ITU Radiocommunication Assembly, considering a) that Recommendation ITU-R BT.2020 defines UHDTV studio signals with 7 680 4 320 and 3 840 2 160 pixel counts, various
11、 frame frequencies up to 120 Hz, 4:4:4, 4:2:2, and 4:2:0 sample structures, and 10 and 12 bit depths; b) that a whole range of equipment based on these signals requires digital interfaces for broadcasting chains and industrial applications; c) that digital interfaces for UHDTV studio signals should
12、support all formats permitted in Recommendation ITU-R BT.2020; d) that digital interfaces for HDTV (HD-SDI) specified in Recommendation ITU-R BT.1120 were originally designed to transport 4:2:2, 10 bit HDTV signals at a frame frequency of up to 30 Hz or a field frequency of 60 Hz; e) that practical
13、optical interfaces supporting a data rate of around 10 Gbit/s are available, and practical electrical and optical interfaces supporting data rates of 6 Gbit/s and 12 Gbit/s and 24 Gbit/s are available, and those interfaces supporting higher data rates will become possible in the future, recommends t
