Using HDMI Input Signals to Insert Text (EFFECT Mode)
Luminance key patterns are used when inserting text with EFFECT mode.
Luminance keying is a compositing technique that involves removing components in the overly video (B)
signal based on brightness (luminance) differences, and overlaying the video on the background video
(A). Typically, bright colored text is created on a black background to be used as a key.
Luminance keying is supported for HDMI input signals assigned to inputs 3 and 4.

Creating the text on the computer
