motorola-docsis-30-modems-cmts-tx32As cable companies transition to super-fast broadband speeds provided by DOCSIS 3.0, they’re also considering how they can move from providing analog and digital channels via radio frequency the way they do today, and instead transition to an on-demand IPTV model that could offer them more flexibility with their programming options. For consumers, this could mean more channels and even personalized content delivered to their PCs and television, on demand.

Part of DOCSIS 3.0 involves faster downstream Internet speeds, which is what most cable companies are focusing on, says Mike Cookish, a product manager with Motorola. However, DOCSIS 3.0 will play a significant role in the transition to IPTV. Cookish says IPTV is being considered at U.S. cable providers; some multiple services operators (MSOs) in Korea and Japan, meanwhile, have already deployed the technology. “The initial target [for IPTV] is the PC and personalized content, and over time, as IPTV set-top boxes become more available, we’ll see a migration where MSOs simulcast some of the channels,” Cookish says. “But they need to free up the downstream channels first.”

Freeing up the channels means doing things like switching from analog channels to digital channels, because a cable operator can pack more digital channels than analog ones into a single slice of spectrum. This allows a cable operator to provide the same number of channels while freeing up spectrum for IPTV trials. Such programs are underway in the U.S. but the IPTV transition is a little further off. In the meantime, the rollout of DOCSIS 3.0 has helped boost revenue at Motorola and Arris, another cable equipment vendor. Motorola estimates it now has 70 percent of the DOCSIS 3.0 market.

    What about switched digital? Cable companies were talking big a couple of years ago about how this was going to free up lots of bandwidth for them. The real issue with IPTV is that to make good use of ti you really need the cooperation of the content providers and that seems to always lag the technological capability by quite a bit.

  2. A move to IPTV will not lower costs for consumers.

    IPTV is still a linear video product. Yes, more efficient and more flexible, but still the packaging of 100s of channels in a box and selling the box to consumers. It is surprising that cablecos would be moving in that direction at precisely the same point in history when viewers are moving away from linear video and toward the infinite expanse of internet (or over-the-top (OTT)) video.

    Linear video (including IPTV) is to the internet video what AOL was to the world wide web.What better lesson could anyone ask for?
