Color Encoding (less than three channels)

When there's only one or two channels / level line, then the colors need to be multiplexed, hence an encoding.

  • NTSC
  • SECAM
  • PAL or PAL/SECAM

SCART plug (multi-signal)

  • plug: SCART 21-Pin RGB / 10-Pin CVBS
  • signals: Composite, S-Video, RGB, YPbPr
  • color encoding: depending on the signal, see below
  • approx resolution: depending on the signal, see below

Composite plug & signal

  • plug: 1 RCA (yellow)
  • signal: single channel CVBS = Color, Video, Blanking & Sync
  • color encoding (single channel): NTSC, SECAM, PAL
  • approx resolution: 480i / 576i

S-Video plug & signal

  • plug: 4-Pin Mini-DIN
  • signal: two channels YC
  • color encoding (two channels): NTSC, SECAM, PAL
  • approx resolution: 480i / 576i

Ref. https://en.wikipedia.org/wiki/S-Video

Component Analog Video (CAV) plugs & signals

Also called Yipper cables

  • either 3 BNC or 3 RCA (red, blue, green)
  • color encoding: none (multi-channel)
  • signal: three channels RGB with sync (RGBS, RGBHV, SoG/RGsB, SoB, SoR, SoC, SoY) or YPbPr (most common)
  • approx resolution: HD ready (analog)
