composite-video - Computer Definition
An analog video color format that combines all three YUV video signals into one channel. The first video signal to include color, composite video transmits brightness/luma (Y) and colors/chroma (U and V) over one cable. NTSC, PAL and SECAM television sets have composite video inputs. Most analog TVs also include S-video and component video connections, which provide a sharper image than composite video. See YUV, S-video and component video. Back to the 1950s Composite video was created when color was added to black & white TV in 1954. The color signal was multiplexed with the monochrome signal and transmitted in the same TV channel (see NTSC).
