If no one in a cable neighborhood is watching one of the 400 channels that no one watches, no bandwidth is consumed.Dave, Switched Digital Video (SDV) has its own interesting attributes, some of which are also potentially anti-competitive. First, I'll note that IPTV systems (like AT&T U-verse) are fundamentally designed to take advantage of distributed architectures. U-verse has its own major problems though -- like the fact that even after the recent upgrades it's limited to no more than two HD streams to a household (plus a number of SD streams) on a single copper pair. While there may be ways to boost this again without compromising video quality too much, AT&T seems to have underestimated the speed with which HD transmissions would themselves become the "normal" fare for most viewers (and indeed, the Comcast/TW bandwidth caps seem to be similarly using standard definition programming as their benchmarks, rather than more realistic HD numbers). But SDV itself has been embroiled in a battle between CableLabs and third-party companies like TiVo who depend on CableCARDs for access to cable company programming. External "tuning adapters" to deal with SDV have just now started becoming available since I wrote (a bit over a year ago): Important Warning Regarding New HD TiVo and Cable System Incompatibilities http://lauren.vortex.com/archive/000273.html and shortly thereafter: The Coax Straightjacket: Stopping Cable Copy-Protection Abuse http://lauren.vortex.com/archive/000310.html Ihe issues of third-party access to VOD/PPV, etc. programming vs. cable industry demands that only *their* software be allowed to access these facilities are still very much in play (the "keyword" in these disputes is "OCAP" - OpenCable Applications Platform). Just ask me if you want more info on these areas.
