Of course, not listed in the table are HDMI video modes. These are a whole other ballgame, but are very similar to XGA
modes and higher.
11.2.3. Composite Color Video Blanking Sync Interface
Composite signals are the most commonly used analog video interface for NTSC/PAL. Composite video is also referred to
as CVBS, which stands for color, video, blanking, and sync, or composite video baseband signal. It combines the
brightness information (luma), the color information (chroma), and the synchronizing signals on just one cable. The
connector is typically an RCA jack. This is the same connector as that used for standard line level audio connections. S-
video of course is slightly cleaner since the analog mixing of chroma and luma does NOT take place. A typical waveform
of an all-white NTSC composite video signal is shown in Figure 11.5.
