TiVo and the National Cable and Telecommunications Association (NCTA) have announced a new external adapter that will allow cable operators to roll out switched video
while still playing nice with third-party devices like the TiVo HD and Series3 DVRs. The devices will hook up to a CableCARD
host device via USB and use software to choose channels, eliminating yet another set-top box but giving cable providers a break on bandwidth requirements. The devices will begin shipping to TiVo customers -- and other compatible CableCARD devices -- in the second quarter of 2008.
