We are working on a video conversion project and I have purchased a ADV7180 evaluation board for prototyping. The input signal could be either PAL or NTSC and the output signal (BT.656) is connected to a 800x600 mini display. As PAL and NTSC have different lines of resolution (645 vs. 525), how can I use ADV7180 to convert them into a a full screen for 800x600? Or do I need extra component to achieve this task? Thanks!
