The device is able to encode the video signals and generate synchronization signals STV format for NTS and PL standards and TV format for 480p,576p,720p and 1080i. nalog R output and composite SY signal are also supported. The device accepts different data formats including R and Ybr (e.g. R565, R666, R888, ITU656 like Ybr, etc.). 16Mbit SRM is embedded in package. rame rate conversion and Image rotation are possible.
