Cablevision Is Sued Over Its ‘Network DVR’

Hollywood studios and TV networks are asking a federal court to stop a video-on-demand service that Cablevision Systems Corp. planned to start offering next month.

The companies sued Cablevision, the nation’s sixth-largest cable TV provider, in U.S. District Court in New York, saying the service, known as a “network DVR,” violated copyrights.

Cablevision announced in March that it would offer subscribers a way to retrieve recorded shows from the cable company’s system. A Cablevision spokesman said the suit reflected a misunderstanding of Cablevision’s technology and the rights of viewers.
