Sorry for the intrusion but what about setting the default value of the "tv:" resource to be the current live tv channel/station/picture whatever it may be for a given household/device. My understanding of current set-top design methodology suggests that the set-top's tuner can be easily 'asked' for its current setting/station. Default would simply be "tv:" with no parameters When I worked at NetChannel with the experimental Navio set-top box we'd designate an image (stream) of type tv by invoking "img src=tv: " .With no parameter this would imply the current picture/station or whatever other source may be applicable (VCR, DVD, VHS etc) When one wanted to select a specific channel (say "6") we used "tv:6" to designate the 'local' channel lineup as determined from the user's geographical location as mapped against the particular cable system that user belonged to. We almost always knew what network/program etc. a given cable channel would be. Given this knowledge it should be a relatively minor issue to find a specific program or network for any given user. The same could be said for a designator of type "tv:nbc" also. One can easily infer from web server environment variables that tv:nbc As far an unique is concerend. The problem could be easily rectified by referring to a simple database of cable channel lineups for a given area. The difference is on what station I might find CBS in my area, this can be determined by simply asking the cable system in question. Sorry if any of this is repeat. Just thought I'd offer a few words. Frey Craig A.
