This has nothing to do with analog TV. There are several bt8xx, saa713x and cx18 products focused on video surveillance systems. Basically, analog cameras connected to the capture boards using coaxial cables, like those: https://www.camsecure.co.uk/Camsecure_video_capture_cards.html Yeah, those are also being deprecated with time with IP-based cameras, but still there are a lot of such products using analog ones out there. Funny enough, even analog TV seems to still be used on some places. We recently merged some patches addressing some issues with PAL/N' on some drivers. Thanks, Mauro
