Camera Synchronous

In this project i designed a board to synchronous the camera output signal with the reference signal.

This project used in places that more than one camera are capturing together and director wants to switch between one camera to other immediately and lively for example in live news TV studios.

Issue:

If cameras not sync together , when switched from one camera to other the output maybe like this:

TV_NOT_SYNC

Solution:

This project used in places that more than one camera are capturing together and director wants to switch between one camera to other immediately and lively for example in live news TV studios.

One board need for each cameras to sync with reference signal,usual reference signal is outputted from one main camera or studio main monitor or edit tables.
