INTRODUCTION TO VIDEO SIGNAL TIMING
The video signal contains a large amount of information.
In addition to
basics such as hue, brightness, and saturation, the television video signal
includes horizontal, vertical, and color timing information.
Other
information may be in the vertical blanking interval, vertical interval test
signals (VITS), vertical interval reference signals (VIRS), time code,
closed-captions, teletext, etc.
Therefore, if optimum results are to be
achieved, the timing relationships between the signals must be carefully
maintained.
A critical step in any teleproduction facility is the system
timing.
The final end product will reflect the quality of the system
design. This subcourse will also define subcarrier and horizontal phase and
explain how to maintain SC/H phase.
