, England. Singapore was the first country in the world to launch an interactive information service to the public which included photographic images. The service started trials during late 1987 using specifically designed terminals. Controlled trials had been conducted since 1987 as the infrastructure was installed and trialed successfully. It finally went into full public service in 1991. Subscribers connected to the Teleview, now-defunct, service by SingTel, via a dial up connection initially by 1200–2400 bit

to a UHF TV transmitter fitted with Full Field Teletext inserters. Transmission of lower level protocol data and user terminal management control was via telephone V22 modem. High level data such as geometric and photographic displays sent exclusively by full field teletext with interchange control and handshaking via V22 modem. The service profile is based upon extensions to the existing CEPT Videotext Services Recommendations T/CD 6-1, as defined in Teleview Videotext Service Profile and Data Standard Ref; 7630/DS/1 1987.


Terminal

The terminal was based upon two Motorola 68000 processors: one as a general main computer and control and the other as a video processor interfaced to VRAM video memory with
