The TV video input module is used to interface external TV video decoder chip. It handles VESA
Video Interface Port(VIP) 8-bit/16-bit YC
and double clock edge input RGB data formats. It extracts embedded sync timing and converts data
into RGB color space. All the functions in this module are controlled by the system microcontroller
through I2C registers.
The following table describes the different pin configurations for YUV/RGB digital input.
