2.2.12. Color Space Conversion

Although all processing in the ADV8003 is performed in the YCbCr color space, the part is capable of receiving video in the RGB, YUV
and YCbCr color spaces. The ADV8003 provides any-to-any CSC on each of the inputs and on both of the outputs (five color space
converters in all). All CSCs support formats such as RGB, YUV and YCbCr. The front end CSCs on the primary input channel, secondary
input channel and RX input channel run at a maximum clock rate of 162 MHz. The back end CSCs in HDMI TX1 and HDMI TX2
operate at a maximum input clock rate of 300 MHz.
2.2.12.1.

Primary Input Channel CSC

The CSC must be manually configured for each color space conversion. The CSC on the primary input channel can be enabled using the
vid_csc_enable control. The CSC mode on the primary input channel can be configured using vid_csc_mode[1:0]. The CSC mode is used
to define the fixed point position of the CSC coefficients which are located after vid_csc_mode[1:0] in the IO Map for the primary input
channel.
Reference configuration scripts to configure the primary input channel CSC are provided with the evaluation software.
