7.22 Color Space Information Sent to the DPP and CP Sections

The HDMI section sends information regarding the color space of the video it outputs to the DPP and
the CP sections. This color space information is derived from the DVI/HDMI status of the input

from the input stream.
The color space information sent by the HDMI section to the DPP and CP sections can be read via
the HDMI_COLORSPACE.
