PHeText teletext system

Important announcement
Unfortunately, teletext inserters can no longer be supplied. The current USB inserter can no longer be produced because essential components are no longer available. As the demand for teletext equipment continues to decline, we have had to decide not to develop a new inserter.

PHecap has a unique teletext system developed consisting of an in-house developed inserter card and a user-friendly software package. Our low-cost system is specially designed to meet regional and local broadcasting teletext. The editing and the broadcast can be done from a single computer, but our system can be arranged so that editing and managing the pages can take place at a distance, including via the Internet. We help you to find the perfect solution.

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.

Editing Software
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.

Hardware Features
  • Plug & Play PCIe card or external version.
  • Processor on board, teletext transmission continues as long the PC power is on.
  • 2Mb page memory, over 2000 pages in transmission.
  • Very fast loading of pages, over 250 pages per second, so 2000 pages in less then 8 seconds.

  • All above mentioned settings are stored in non volatile ram on the card (EEROM). So after a power failure all the settings are maintained.
  • Test pages in ROM on the card. So after power on you have always a transmission.
  • Display of sub pages.
  • Display of "rolling header".

USB Teletext Inserter

There are two versions of this newly developed inserter, one version for mounting in a PCIe slot internal in a computer and one version in a separate housing.  The internal version is powered by means of a drive power connector (12 V). The external version is powered with a external plug in adapter. Both versions communicate with the computer via the USB interface, the internal version can either be connected with a flat cable to the motherboard or with a external USB-cable. New features of the USB Teletext Inserter:
  • Bypass relay, the video signal is fed through at a power failure of the inserter.
  • Internal sync generator, at the absence of a video input signal the internal sync is switched on.
  • TV test pattern, checkerboard selectable 3:4, 16:9 letterbox or amorphous.
  • WSS-signal, selectable 3:4, 16:9 letterbox or amorphous.
  • Supported by all 32 and 64 bits Windows versions from XP to Windows 10.
