Burst (color burst)
CCTV glossary (глоссарий терминов по видеонаблюдению) |
- Seven to nine cycles (ntsc) or ten cycles (pal) of sub-carrier placed near
- Seven to nine cycles (ntsc) or ten cycles (pal) of sub-carrier placed near the end of horizontal blanking to serve as the phase (color) reference for the modulated color subcarrier. burst serves as the reference for establishing the picture color.
- Сигнал цветовой синхронизации ("вспышка"). от семи до девяти (ntsc) или до десяти (pal) периодов поднесущей размещено на конце строчного гасящего импульса в качестве фазового (цветового) опорного сигнала для модулированной цветовой поднесущей. сигнал цветовой синхронизации служит эталоном для цветного изображения.

Horizontal, английский
- Горизонталь; горизонтальный
- Горизонталь; горизонтальный 287
- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a
Subcarrier, английский
- Поднесущая
- The 4.43 mhz (pal) or 3.59 mhz (ntsc) signal that is used as a carrier for the color information. this subcarrier is modulated in amplitude by the color saturation and in phase by the color hue. a sample of the unmodulated subcarrier is placed before the start of each horizontal line, and is called the color burst.
- Signal which is transmitted along with the main video signal carrier. s can transmit data, color picture information or audio.
