4 Primary Mode and Video Standard

Setting the primary mode and choosing a video standard are the most fundamental settings when
configuring the ADV7604.
There are three main modes of operation on the ADV7604.
• COMP
Analog-component video mode. This includes all video signals that arrive in a YPbPr (or
YUV) analog format. Typical examples are progressive and high definition video signals.
This mode is enabled by setting
• GR
Analog-graphic mode. This mode is intended for RGB input signals with high bandwidth.
This mode is enabled by setting
• HDMI
HDMI mode. In HDMI mode the ADV7604 can receive and decode HDMI or DVI data
throughout the DVI/HDMI receiver front end. Video data from the HDMI receiver is routed
to the DPP and CP blocks while audio data is available on the audio interface. This mode is
enabled by selecting either the HDMI (Graphics) primary mode or HDMI (Comp) primary
mode.
