I don't think this is correct. From what I understand about DOCSIS, the video-related channels and Internet-related channels are completely separate frequency ranges on the coax line. The reason your bandwidth is reduced during peak usage hours is because you're sharing something like a 10gbps fiber line with hundreds of other people.

Yes, that's why they can use band pass filters to enable and disable specific services and packages. i.e., specialty channels that are part of a premium package are grouped together in certain frequency ranges, and they use equipment to block or allow signals at varying frequencies on each consumer connection.

But doesn't their VOD service use a DOCSIS packet connection?
