PAL/NTSC Video Time/Date Generator

Posted on Aug 25, 2012    3411

The following design is capable of overlaying the time and date onto any existing PAL (or optionally NTSC) composite video signal. It is housed in a very neat and compact standard moulded casing and has standard 75ohm RCA video inputs and outputs. A single +9V to +15V DC supply is used to power the device, which can be taken from an existing camera supply if desired. As a bonus the design is also capable of displaying a 10 character user defined text message along with the time and date.
