I picked up a couple of tidbits in a meeting today and will probably explore them further in the future.
One: In the next several years we’re likely to see operators start increasing their data channels in relation to their video channels. While video channels into the home will still outnumber data channels, the amount of data channels as a percentage of the whole broadband pipe is likely to increase. (Think about all the bandwidth you’ll be using for online applications in a few years.) Switched digital video will help out on that front.
Two: Apparently a big issue in cable modem termination system (CMTS) design is avoiding energy leakage between channels – DOCSIS channels and others. That’s really all I’ve got on that one, but I thought it was interesting.
