Introduction SMPTE ST 2081-12 defines the mapping of various source images and associated ancillary data into a Quad-link 6 Gb/s nominal SDI bit-serial interface. The general process for creating a quad-link 6G-SDI is illustrated below in Figures 1 and 2. Deta
13、iled definitions of how this process applies to each of the modes defined in the scope follow in other sections of this document.

20、2081-12:2016 Page 5 of 46 pages The source images are divided to into four or sixteen 1080-line sub images as appropriate to the source image format. The sub images are then mapped on to a 160-bit virtual interface consisting of sixteen 10-bit data streams. Each 10-bit data stream includes timing an
21、d sync words, line numbers, cyclic redundancy codes, ancillary data, including audio, and payload identification packets. Multiplex The 160-bit virtual interface is then multiplexed onto four 6G-SDI 10-bit interfaces. The first four data streams are multiplexed in the order data stream four, data st
