New York Times reports:

The Supreme Court on Monday delivered a blow to the television networks when it declined to hear a case about a digital video recorder technology, opening the gate for wider use of DVR systems.
The case began in 2006 when Cablevision Systems, the New York-area cable operator, announced plans for what is called a network DVR system. With it, a customer would use a remote control to digitally record a program like “60 Minutes” but instead of storing the show in the customer’s at-home DVR box, the technology would store the show on a faraway Cablevision server.
The technology would let Cablevision convert set-top boxes into boxes with DVR capabilities without requiring an installation or new equipment.
