Rev 3.00
July 26, 2016 Low Cost Video Format Converter
The TW8809 is a low cost video format converter that can take
either analog CVBS or 24-bit digital RGB format video and
output these signals in ITU-R.656 format. The video sources
can be scaled and deinterlaced, so that the ITU-R BT.656
output is already formatted to the desired resolution and in
progressive format. In addition, the TW8809 has built-in OSD
and image enhancement capabilities.
