SMPTE 2046-1 – Specifications for Safe Action and Safe Title Areas for Television
This Standard defines and specifies Safe Action and Safe Title Areas for 1920 x 1080, 1280 x 720, 720 x 576 and 720 x 480 television formats. This document is intended for application in program production where the image aspect ratio of the acquired essence is the same as that of the display.
The safe areas defined in this Standard differ from past practice; they take into account changes in image acquisition, transmission and display technology. They do not offer guidance in situations where material generated in one aspect ratio may need to be displayed in a different aspect ratio.
