The information may be of use to other people, so I hope you don't mind me
posting this reply.

Try the SAA1043 "Universal Sync Generator" (not sure of the manufacturer).

The part appears on page 416 of the Maplin Electronics catalogue.

It writes "The IC generates the synchronising waveforms required in all types
of video source equipment e.g. video cameras, film scanners, video games,
computer displays etc. The device is programmable to suit standards
SECAM1, SECAM2, PAL/CCIR, NTSC1, NTSC2 and PAL-M; the video game 624 and
524 line standards; and can be synchronised to an external sync signal".

It is a 28 pin device, and costs 9 pounds (about 15 dollars).

Disclaimer - I have never used this device, but it sure sounds suitable.

Maplin Electronics is a mail order company which supplies a wide range
of electronic components to the hobbyist. They started off small, and 
grew large as a result of good service. They now have several retail
outlets around the country (in the larger cities such as Bristol). These
outlets are very good (as compared with T*ndy/R*dio Sh*ck), and have an
enormous selection of components/kits/books/tools etc. Their catalogue
is over 600 pages in size and costs 2 pounds 50 pence. It is now available
from most reputable newsagents (no US translation :-) ). They do accept
overseas orders. They also run a bulletin board type service, over which
you can order parts and pay by credit card.

Note: I am not connected in any way with this company - just a satisfied
customer.

Other video related parts they currently sell: LM1881 "Sync Separator" ;
TEA2000 "PAL Colour Encoder" (RGB digital to PAL video - NTSC also
supported) ; ZNA234E "TV Pattern Generator" (generates crosshatch/dots/
greyscale test patterns in PAL/NTSC video standards). 

Maplin also produce their own electronics magazine, and their projects
tend to feature devices which they sell. They recently had projects
on both the TEA2000 and ZNA234E parts, and so PCB's and kits are
available.

Please mail me directly if you require any more details. I believe another
poster may be interested in the TEA2000.
