Baseband Video is an unmodulated video signal that requires a dedicated channel. It’s used in analog CCTV systems and delivers higher quality than RF-modulated signals.
This is the video signal used in CCTV. It is the NTSC or PAL format minus the broadcast frequency modulation and many other embedded signals used in Broadcast TV. It consists of video, horizontal sync and vertical sync. This is all that is required to view a video signal on a monitor.
