I believe this depends on the implementation. Almost certainly in large (expensive) IPTV installations VQE server is not listed in the SDP - because there is not just one VQE server (due to redundancy), and there are redundant receivers going into redundant encoders and then they go into (in some cases) redundant streamers. They have existed for a few years when you add your first bunch of VQE servers - which run independent on the rest of the hardware.
Probably configuration of which VQE servers are responsible for which channel streams is info transfered to STB during boot process (probably in proprietary way).
Which would be no problem - VQE is UDP based so one could easily use anycast to let the IGP decide which Server to use.
I believe STB buffer has to be big enough. I will have one of the implementations (Edgeware) on test next month, so then I wil be able to see how it's implemented.
The point is the delay - Buffer/Memory is not the problem but broadcast delay. Flo -- Florian Lohoff f@zz.de Professionell gesehen bin ich zu haben ....
