16.0 Video Legalizer This parameter determines the Video Legalizer mode. When set to Off, the Video
Legalizer is not enabled, and the following clip controls are not active. In YUV mode, the
White Clip, Black Clip, and Chroma Clip controls are enabled and clip any luma/chroma
that exceed the set limits. In RGB mode only the White Clip and Black Clip controls are
active and limit the R, G, and B values to those settings. RGB mode requires the video to
pass through the RGB Proc Amp to be converted to and from RGB.
16.1 Legalizer White
Clip
When the Video Legalizer mode is YUV or RGB, this parameter limits the white level so
that it does not exceed the adjusted limit. Limit can be set from +80 IRE to +120 IRE.
16.2 Legalizer Black
Clip
When the Video Legalizer mode is YUV or RGB, this parameter limits the black level to the
adjusted limit. Limit can be set from -10 IRE to +20 IRE,.
16.3 Legalizer Chroma
Clip
When the Video Legalizer mode is YUV, this parameter limits the maximum chroma level
to the adjusted limit. The limit can be set from +60% to +140%,.
AFD
These parameters determines if and where the Video Processor will insert a SMPTE 2016
Active Format Descriptor (AFD) packet into its output video. The inserted AFD code does
not affect the Video Processor's up/down/cross conversion, but it may affect downstream
video processing if the signal is Downconverted.
NOTE: AFD codes are only inserted into HD video outputs.
