| I have added Acorn Teletext Adapter support to BeebEm.
The software works in conjunction with a TV capture card in a Windows PC. The idea is to eventually write a piece of software for a Windows PC to act as a networked teletext server. This would constantly capture teletext data from the TV card and sends it via UDP to a copy (or copies) of BeebEm anywhere on the net. I haven't written the network server software yet but I have put together a Direct Show filter using the DirectX SDK which captures raw teletext data to disc files. These disc files can then be used with BeebEm to serve teletext data to the emulator. There are four sample teletext data files in the archive below (txt0.dat, txt1.dat, txt2.dat, txt3.dat). These contain several minutes worth of teletext data from BBC1, 2, ITV and CH4, which was captured on 22 Jan 2006. If you download the archive and copy the four files to your discimg directory, you will be able to view the pages using the *TELETEXT command. I would also recommend downloading the user guide as well so you know how to drive the teletext software.
Here is another sample of teletext data captured on 4th April 2006. |
