a. you need a ttx editing software, to produce teletext pages.

you can find this on the internet.

b. rs-232 is very common as a data mean between the pc and your inserter.
some software will produce this interface, other options are parallel or ethernet interface.

c. you can use a video encoder device for the teletext insertion like philips.

Hello

I am interested in construcion of teletext inserter too. I think the best way to make it will be a circuit based ona a FPGA or similar part connected to dual port RAM (I'm regarding IDT7132 chip cause I need only 2 teletext pages to transmit). On the other port of RAM would be any microcontroller to upload pages into memory. That idea is very familiar with that given by pasicr:
