Figure 9-7 Block diagram video processing
"Block diagram video processing" shows the input and output
signals to and from the Trident Video Processor.
During analogue reception, a CVBS signal coming from the
analogue front-end is fed to the video processor via pin
CVBS1. During digital reception, the video signal coming from
the MPEG decoder (MOJO) is fed to the video processor via
pins FS1, PC_B, PC_G and PC_R.
The video processor also interfaces the SCART1 & 2 input,
side AV, EXT4 (HD where applicable) and HDMI1 & 2 and Side
HDMI input. Through the SCART1 & 2 connectors, a monitor
output is foreseen.
