Sequential Colour with Memory (SECAM) Analogue Television Broadcast. Now phased out in most of the world. Replaced by DVB-T. Used Frequency Modulation for transmitting video. Uses CCIRComité Consultatif International pour la Radio (Predecessor of the ITU-R) System B.
Has a Field Rate of 50 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz)., 625 lines per frame, and a Gamma of 2.8.
Format[edit]
Luma: Amplitude Modulation. The amplitude denotes the brightness on each scan line.
Chroma: Used an analog FMFrequency Modulation system, where the frequency denoted the saturation of color, and the phase denoted the hue. This uses the DbDr (YDbDr) color system.
Audio: Standard AMAmplitude Modulation or FMFrequency Modulation modulated audio.
In addition, there are multiple systems of SECAM that are employed.
Frequencies[edit]
All over the VHFVery High Frequency (30-300 MHz) and UHFUltra High Frequency (300-3000 MHz) bands.
