Bell ExpressVu TV For Condos is delivered from a head end to a local DSLAM over fibre (aka basement of the condo) and then up the elevator shaft / access shafts via existing twisted pair phone lines, sharing TV, Internet and POTS. Because the run lengths are relatively short, more reliable bandwidth can be assured. The existing VDSL product maxes out at around 15 mbps; the improved version, VDSL2/VDSL2+ with IPTV maxes at around 26 mbps; with pair bonding (using four wires instead of two, and assuming they are available to the suite), pushing out to 40 mbps is possible.
My understanding is the current version about to release -- referenced above -- is the 26 mbps variety. Therefore 1 HD stream (8-10 mbps/MPEG4) + 3 SD streams (3 mbps each) + 6 mbps Internet maxes out the pipe. This leaves no room for a 2nd HD stream; or HD PVR capability. However, most of this "enlightened speculation" since Bell hasn't formally announced the service or hardware specs.
The closest model is believed to be AT&T U-Verse; PVR is available but not HD PVR; only one HD stream is available. The service has had serious scalability problems as was limited to 3000 homes as recently as last December. By late May, AT&T was reporting 20,000 homes subscribing.
