Teletext on 4
Utilising the established public perception that a Teletext information service pops onto the TV screen when you press the TEXT button from the days of analogue TV, Teletext successfully secured such a position in the world of Digital TV on Channel 4 (inc. E4, E4 +1, Film Four and More 4) on Freeview and Sky. The main focus of the design for Teletext on 4 was usability, accessibility, and the delivery of relevant content using minimal bandwidth, whilst maintaining commercial viability. These values have been applied cross-platform and cross-application (see
Teletext on ITV) as the business took opportunity to standardise their suite of iDTV applications, to speed up the development process and create a consistent user experience.
