PHeText teletext system
The heart of the PHecap teletext system is the in-house developed USB teletext inserter. This inserter we can deliver in two versions: a single version that is installed in a PCIe slot of a PC and an external version in a separate enclosure. In both cases, the inserter communicates with the PC via the USB interface. The internal version can be directly on the motherboard or connected to an external USB cable.
Along with the teletext inserter PHeTxtServer is the broadcasting station for teletext. PHeTxtServer is software which is installed on the same PC as the teletext inserter. This software allows for the actual update of the teletext pages. The updating takes place via the internet and uses the FTP protocol.
The PHecap teletext system is flexible. We have developed software that allows the creation of the teletext pages can be done in different ways. The PHeText editing and broadcasting software can be installed on the same PC as the teletext inserter but this software can be installed on any other computer also. Additionally PHecap has also developed software where it is possible to edit the teletext pages over the Internet. For example, associations and municipalities can fill the pages assigned to themselves.

A teletext page has a very special construction. Use is made of so-called serial attributes to indicate color, double height etc. See the manual on the download tab.
