I agree. Additionally, I think I hear that there is some desire for a single scheme to refer to broadcast data AND audio/video programming. It would probably be better to separate these two efforts, and to make a basic and simple scheme that can be built upon later. In my mind, there are a few basic requirements that would solve the problems of content authors for referring to a/v programming: - It should be simple to write a URL that says: "tune into this channel" - And a little bit harder to write a URL that says: "tune into this program" - And it shouldn't matter if I'm watching it on cable, terrestrial or via satellite. To do this, some kind of authority or database will be needed to resolve tuning parameters from channel & program identifiers, just like DNS is needed to resolve IP addresses from domain and host names. Electronic Program Guides (EPGs) are one way to do this, but a more centralized system (or a hybrid) may also be appropriate. -dean ------------------------------- Dean Blackketter WebTV Networks, Inc. 1295 Charleston Road Mountain View CA 94043 <mailto:dean@corp.WebTV.net> Work: (650) 614-5521 VM & Fax: (415) 680-2357 Home: (415) 863-5737 Mobile: (415) 819-6564
