Thanks, Alan, for posting this (I have read this and many other pages at the intercast site looking for technical specifications, but to no avail...) > >From the Intercast FAQ at http://www.intercast.org/info/info08.htm : > > Q5.

I think one should read between the lines... since here in europe we have Teletext almost everywhere since the early 80's, and at least in Italy (but I am sure in many many countries) major broadcast companies sell "pages" for commercial purpose (from advertising to software distribution), I have a hard time believing that there are technical or legal impedements to the deployment of something like intercast outside the US. Probably it's merely a question of whether or not there is a sufficiently large market to encourage companies to license the intercast approach as opposed to using public specifications such as Teletext, or proprietary encodings (which is what many are doing now). > Intel is investigating > the internationalization of the Intercast technology. ... As an aside: my TV unit (bought in 1992 but probably designed a couple of years before) has a browsing mode for teletext pages which is almost the same as Lynx, and when I bought the TV I had not seen yet a www browser! Intercast just adds some stronger FEC protection to data (teletext only has a very weak protection) so that graphics and HTML pages can be sent, and the use of a larger cache for "pages" (typical teletext decoders use a small SRAM as a cache, which can only hold a few (1..32) pages).
