Such universal edge-QAMs can provide bandwidth for multiple services, including switched digital video and video-on-demand, whereas traditional QAMs require channels to be dedicated exclusively to one service, like VOD.

Separately, French electronics-maker Thomson earlier this week announced that Comcast has picked it as a supplier of voice-enabled cable modems, in addition to the MSO’s current deal with Arris for such devices.
