Bipin, You need to look at what you want to do in more detail I think. First off I do not think the NI 5431 will be able to take the .trp files in a MPEG-2 format and generate composite video test patterns. You will have to convert the files to the format needed by the 5431. Second to insert teletext you may want to look at a PCI card from Cebra Technology at http://www.cebra.dk/ You can run the output of the 5431 through this card and generate any teletext you want. The board has a SDK that provides an API.

I am looking at NI 5431 Video signal generator card which can test Television broadcast equipments. Also the test signals are in .trp file (MPEG-2) format. Any information on how to insert Teletext using NI 5431 will be of great help. Best Regards Bipin M Application Engineer, Captronic systems Pvt Ltd.
