For my application I am looking for the composite video blue screen source chip.
Currently for this purpose I’m using the Sanyo OSD chip. The problem I experiencing with this chip, that it generates standard NTSC composite signal and simplified PAL. I need to replace this chip and the first idea is to use ADU7171 video encoder. Unfortunately I can’t find evaluation board and without that I can’t verify if 7171 generates standard NTSC/PAL signals.
Does anybody has any idea how this chip is performing and maybe there is another non expensive solution for the “blue screen” generator?
