Exam 4: Synchronizing Signals

Horizontal and vertical synchronizing pulses are part of the analog composite signal so they can easily be fed to any piece of equipment that requires a sync reference signal.

The interval is comprised of approximately 45 lines of (non active) video and is used for synchronizing information. Signals such as VITS, VIRS, closed captioning, commercial insertion and satellite data can be inserted into these (non active) video lines.

Vertical synchronizing pulses appear at the beginning of each line of video.

A sync generator not only creates horizontal and vertical synchronizing

Digital signals do not require blanking, vertical and horizontal sync signals. Instead each line has two short data bursts called SAV & EAV.

In analog television, the was the reference signal

The heart of a sync generator is an oscillator that puts out a signal called the color subcarrier.

A cross pulse display is a visual image of what is represented electronically on a waveform monitor. This display can be observed on a professional video monitor.

The master house sync generator provides signals to devices that have their own sync generator circuits. Devices that slave to that master signal are

What types of synchronizing pulses appeared at the beginning of each line of analog video?
