English

Subject field(s)
  • Video Technology
  • Television (Radioelectricity)
  • Computer Display Technology
CONT

The horizontal synchronizing signals at the rate of 15,750 per second for each scanning line provide horizontal synchronization.

OBS

horizontal sync; horizontal synchronization : terms officially approved by the Lexicon Project Committee(New Brunswick).

Record 2 2010-01-28

English

Subject field(s)
  • Television (Radioelectricity)
CONT

The horizontal and vertical sync pulses that form part of the composite video signal are separated in the sync separator. The composite video signal is either taken from the video detector output or after one stage of video amplification. A sync separator is a clipper that is suitably biased to produce output, only during sync pulse amplitude of the video signal. In some receivers, a noise gate precedes the sync separator. This suppresses strong noise pulses if present in the video signal.

Record 3 2006-12-05

English

Subject field(s)
  • Television (Radioelectricity)
  • Video Technology
DEF

A signal which consists of 8 to 12 cycles of the chrominance subcarrier(3. 579545 MHz) added at the end of the horizontal sync signal of the TV signal.

OBS

This burst signal is exactly the in-phase and same frequency as the chrominance subcarrier being transmitted and it becomes the reference for phase comparison during reception (amplitude for chroma, phase fo rhue determination) in generating the continuous carrier necessary at the time of deriving the color signal.

Key term(s)
  • colour sync signal
  • colour burst

French

Domaine(s)
  • Télévision (Radioélectricité)
  • Vidéotechnique
DEF

Signal composé d'une rafale de huit à douze cycles dans la sous-porteuse couleur (3,579545 MHz) qui est ajouté à la fin du signal de synchronisation horizontal du signal télé.

OBS

[La salve de synchronisation de chrominance] synchronise la phase de l'oscillateur de chrominance de 3,58 Mhz du récepteur.
