What is the Genlock button for?
The Genlock button is for switching screens when you have the optional Genlock video card fitted, As standard the CDTV screen is visable but if a video signal is connected andyou press this button the CDTV’s normal screen will be merged with the external signal, Pressing the button again will display just the external signal and pressing it again will return the display to just the CDTV’s display. A genlock is normally used for adding titles to home videos but special effects are also possiable. When the CDTV’s signal and the external signal are mixed one colour is kept for the genlock, When this colour is displayed by the CDTV the genlock will fill the colour with the external signal (If 1/4 of the CDTV display is the Genlock colour then only 1/4 of the external signal will be displayed, No scalling of the external signal is possiable).
