Abstract
Aspects of the disclosure are directed to a novel approach for content protection. Specifically, various embodiments employ data feeds to continuously or periodically inform placeshifting devices of protected content. The placeshifting devices then filter or otherwise block the protected content from being re-transmitted over a network based on this information. In some embodiments, the data feeds take the form of Really Simple Syndicating (RSS) or Atom feeds. These data feeds may carry information about the protected content, such as the time, the title, and the channel of specific audio/video protected content. Based on this information, the placeshifting device can determine which content is protected and not eligible for re-transmission.
