Abstract
A base station includes a tuner and teletext decoder 32 which outputs baseband video, audio and raw text data at 36, 37 and 39, along a cabling infrastructure 40. A remote PC 41 has a capture card to receive and display the video picture and assemble the text data into a picture which is stored and displayed as required. The PC also displays a control application window which, by pointing and clicking with a mouse 45, allows control signals to be sent to the tuner 32 to select channels and pages via a microcontroller 34. The text information is subjected to an error checking and re-transmission protocol at the PC.
