WorldGate chief executive Hal Krisbergh says the reason WorldGate can do what WebTV cannot - or more likely does not want to do - is because it controls all the Java applications, like all its other applications, at the cable head end
and then serves the interface down to the cable set-top box, which he says is the classic cable television model.
But even with the proper equipment on the network edge, Keynote's Taylor argues that COs and cable head ends
are not ready for the influx of new bandwidth.
As bandwidth for the last mile has increased, it has shifted the bottleneck to the next link in the chain, the uplinks to the Internet--from the cable head ends
and the xDSL points of presence (POP).
