FOTH Standards Converter Demonstration, Harpenden June 2006
FOTH (Fools on the Hill), is a LINUX based television standards converter using a PC to do the clever bits! It is based on the KNOPPMYTH LINUX distribuition, so with the addition of the relevant interface cards in the PC, is capable of "off-air" conversion from analogue or digital brodacasts, DVD playback, internet video streaming, and web browsing. The PC can aslo be used as a "hard disk" type video recorder.
The hard development work was done by Kat Manton, and first demonstrated at the National Vintage Communications Fair, held at the Warwick Exhibition Centre in the Spring of 2006. I was the test dummy, to see if the results were repeatable.
I was asked to take my system along to the BVWS meeting at Harpenden, in June 2006, to demonstrate the system.
My system consists of a PC with a Pentium 4 processor, 256MB of RAM, 80GB hard drive, DVD / CD drive, 100M LAN, and a Hauppage TV card, running the KNOPPMYTH LINUX package, with modifications to the X-windows mode line. There is a RGB / Synch combiner to Kat's Mk2 design, and I'm using a Philips PM5511B pattern generator as a VHF modulator.

A new op-amp based RGB combiner which I have under development.
