Problem in display • Many Web pages are too complicated. • Lower display resolution (generally 640x480) ↓ HTML guideline for Web access from TVs is necessary. (Like Compact HTML for small information appliances)
Problem of WWW access via phone line Telephone charges are expensive in Japan. ↓ VBI data broadcasting • Push technology • HTML data is sent to TVs • Access via phone line when detailed information is needed.
VBI data broadcasting Two different ways in Japan • Bitcast (by INFOCITY) TBS, MBS, Fuji TV • ADAMS TV-asahi and 24 ANN stations
VBI data broadcasting • Not related to the TV program broadcast • Need hard disks to save the contents broadcast (for PCs not TVs) • Life of disks are shorter than TVs ↓ • We need VBI data broadcasting tuned for TVs
Conclusion • Easy manipulation by remote control unit • Lower display resolution →HTML guideline for Web access from TVs is necessary. • VBI data broadcasting for TVs is necessary.
