I think you've missed what IPTV is here, Jun. IPTV is a system for service providers to provide television services over high-speed internet connections (Cable Modem or ADSL2, for example). An example would be the UK "HomeChoice" system, where "HomeChoice" provide a DSL line and a STB that connects to it. They then have a smart client on the STB that requests programming from "HomeChoice"'s content servers, which is unicast/multicasted to the STB using TCP/IP over the DSL link. This also enables the STB to make use of the content server's large capacity, by requesting a specific program from a specific time to be streamed, rather than just "Live TV". At least, I hope that's what version of IPTV this thread is about, otherwise I have inserted my foot very firmly into my mouth on this one. :) -- Robert "Anaerin" Johnston _______________________________________________ mythtv-dev mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-dev
