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. |

1. A method, comprising:
a content provider causing one or more media programs that are not intended to be retransmitted over one or more communication networks to be determined; the content provider causing one or more characteristics of the one or more media programs that are not intended to be retransmitted over the one or more communication networks to be determined, the one or more characteristics comprising at least one of: one or more presentation times of the one or more media programs, one or more presentation channels of the one or more media programs, one or more estimated or actual durations of the one or more media programs, and one or more broadcast areas of the one or more media programs; and the content provider causing one or more data feeds to be transmitted over the one or more communication networks to a placeshifting device, wherein the one or more data feeds comprise the one or more characteristics of the one or more media programs that are not intended to be retransmitted over the one or more communication networks, wherein the one or more media programs are received at the placeshifting device separately from the one or more data feeds comprising the one or more characteristics of the one or more media programs, wherein the one or more characteristics of the one or more media programs are determined so as (i) to identify that the one or more media programs are protected such that the one or more media programs are prevented from being retransmitted over the one or more communication networks and (ii) to identify the one or more media programs to the placeshifting device such that the one or more media programs are prevented from being retransmitted over the one or more communication networks by the placeshifting device, and wherein all media programs belonging to a certain category are prevented from being retransmitted over the one or more communication networks in response to receiving a threshold number of data feeds indicating that the certain category is protected. |
