2 Normative references
EIS applies the following publications by dated reference; only the editions listed apply. Rack dimensions quotes the figures EIS takes from the IEC publications.

data/video_timings.json names the publication behind each format. The raster figures of 8.3 agree with those publications and, where a row has a contract entry, with a hardware-verified timing contract, which tests/video_timings_contract.py checks.
Inherited conventions
EIS restates these conventions in its own words. The pages are not normative references, and a change to them does not change EIS; they are cited so that every inherited requirement in the register names its origin.
