As a broadcast engineer for the company who provides the technical facilities to ESPN/Turner for the broadcasts of NBA games, I can say this network is only used for the statistics data.
the live webstream is generated by an entirely separate entity who derives their video from our cameras, but as for their transmission, i believe they transfer from site to NBA.com offices via the house WAN (typically t3 trunks)..
networking in television production trucks, while rather basic, employs some pretty interesting technologies... the EVS machines (basically really advanced dvr's that allow for "live slowmo", and creation of clips from the incoming video signals instantaneously, for all those instant replays) transmit all audio/tvideo to a proprietary dataserver located inside the truck by use of a proprietary coaxial network (called sdti)
as for your hd broadcasts, those still go out the old fashioned way, via satellite...
and i gotta tell you.. if you own an hdtv, you're getting hosed by your service provider. it's crazy how bad the signal you get at home is in comparison to what gets beamed to/from that satellite.
