Speaking this week at the CableLabs Financial Analyst Conference in New York, Time Warner Cable CEO Glenn Britt said the company's primary thrust in 2006 has been to employ switched digital video (SDV). The technology frees up bandwidth on cable systems by delivering fewer channels to the cable-box, and keeping the rest waiting at the edge router.

A trial of the technology in Austin resulted in bandwidth savings greater than fifty percent, according to Time Warner execs. Out of the 1,000 homes in that trial, 45 out of 170 channels were being simultaneously viewed. The remaining un-used channels still gobbled up network bandwidth while sitting un-viewed.

Time Warner, the most aggressive MSO on this front, says they've deployed this technology in three markets, with four to six planned next year. When asked about the cost of such an initiative, Britt states the MSO rolled out switched digital, digital simulcast and "Start Over" technology in one recent market for about $16 per home.
