A growing number of cable operators are deploying switched digital video (SDV) technology, which frees up bandwidth on cable systems by delivering fewer channels to the cable-box, keeping the rest waiting at the edge router. In current cable systems, all channels are consistently made available to the set-top box, using up valuable bandwidth even if your TV is off. Unfortunately, the new two-way SDV technology prohibits one way CableCARDs from working, so TivO and the cable industry have been working on a new adapter since last year.

A Cox Communications rep has stopped by our forums to note that they’re now offering TiVO turning adapters in their Arizona market (they’re already available in Cox’s Fairfax County, VA and Fredericksburg, VA markets). “Tuning Adapters are now available and are being offered to Cox Arizona Digital Cable customers with a CableCARD in a TiVo Series 3, TiVo HD and TiVo HD XL digital video recorders at no charge,” says a Cox technician.

Both Time Warner Cable and Cox were fined by the FCC by making the switch to SDV in a number of markets before a solution for TiVO customers was made available.
