Section 27 Video Display Controller 3
27.1 Overview
The video display controller 3 provides the following four functions. Note that the video display
function and video recording function cannot be used together.
1. Video display function: Reduces the size of the input video, buffers the resultant video data in
the memory, and then displays the video on the panel.
2. Video recording function: Stores a specified number of input video fields in on-chip large-
capacity RAM or SDRAM.
3. Function for overlaying graphics images (two planes) on the input video.
4. Function for outputting the control signals for the TFT-LCD panel.
