Time Base Corrector

The integrated Time Base Corrector avoids unsynchronized distorted images of VHS tape recorders
or any other unstable video source. It is a true one field TBC and will solve many synchronization
problems occurring with digital video projectors and especially the new LC-or TFT-Displays, which
require a very stable sync signal for proper operation.
