data/video_timings.json names the publication behind each format. The raster figures in 7.3 agree with those publications and, for every row that has a contract entry, with a hardware-verified timing contract, which tests/video_timings_contract.py checks.

Inherited conventions

EIS restates the following conventions in its own words. These pages are not normative references: a change to them does not change EIS. They are cited so that every inherited requirement in the register names its origin.
