Teletext is used in Europe and other parts of the world to transmit digital data along with a television picture. Teletext data is transmitted in an invisible part of the TV picture called the "Vertical Blanking Interval" or VBI.
Teletext data is normally formatted into pages. A master index is also transmitted which lists the various categories that can be received, and which Teletext page they are being transmitted on. Teletext data must be inserted into the VBI by your TV broadcaster, and can only be received on the WinTV USB if the Hauppauge Teletext decoder is installed.
An example of a Teletext page follows. Each Teletext page has a page number, a date and the current time in the right hand corner:(The time shown in a selected page will only Update if “Update Continuosly is selected- see later, in this section).
VTPlus for WinTV USB is a sophisticated Teletext software application which runs exclusively on the Hauppauge WinTV. VTPlus allows you to view multiple Teletext pages, save or print Teletext pages and create Dynamic Data Links so that Teletext data can be used in other Windows applications. The WinTV application does not have to be active while the VTPlus Teletext application is run- ning.
