Telidon — ‘knowledge at your fingertips!’ (1981) CBC – Watch it here

Videotex article in the swedish magazine ‘Mikrodatorn’ nº5 (1983)

Viditel was a Dutch videotex standard, launched in 1980. With a special vidimodem and a homecomputer, you reached out in the world in teletext style. There were about 30,000 users. More info here and here.

Obscure C64 textmode software from 83/84. Microtel 600 was for videotex (Viditel in the Netherlands) and telesoftware (software that you download through teletext). Com-In seems to be for radio communication (RTTY) and other things. The software at the top (PA3ASM) is some sort of assembler or machine code monitor?

Pics from here. Thanks to Akira for the suggestion.

Some teletext/videotex standards offer more than alphanumerical characters. Like the Canadian Telidon, which used vector graphics. These are Telidon images, made by Jacques Palumbo in 1986.

Meanwhile in Japan, videotex was more complex: it was alphaphotographic. That is a combination of text and hi-res photos. It supposedly worked like a fax machine for the TV. See Captain.

Telidon (1978) was a Canadian videotex service with both text and vector graphics. It could be used for mass communication on TV, or two-way communication using modems. Telidon required more complex decoding than its competitors, normally using Z80 or 6809 processors. Via.
