Abstract: A method includes determining a data capacity of a first network device of a plurality of network devices that provide content to a set-top box device. In response to the data capacity satisfying a first threshold and a second threshold, sending a first command to the first network device. The first command instructs the first network device to store media content associated with a particular channel corresponding to a predicted channel change request at the first network device. In response to the data capacity satisfying the first threshold and failing to satisfy the second threshold, sending a second command to the first network device and sending a third command to a second network device. The third command instructs the second network device to store the media content associated with the particular channel.

Abstract: A system and method is disclosed for detecting distribution of multimedia content. The volume level of data traffic is monitored for a plurality of users to select any users with high-bandwidth usage. The time of day and the day of the week may be considered when determining whether a user is a high-bandwidth user. Upon selecting a user as one with high-bandwidth usage, such user may be subject to packet inspections of data traffic streams. In some embodiments, content identification parameters or watermarks are added to one or more packets in a data traffic stream carrying multimedia content.

Abstract: A method includes inspecting a packet stream sent from a set-top box device via a network. The packet stream includes video content that is divided into a plurality of subsections. The method includes generating a plurality of signatures by applying a wavelet transform to each of the plurality of subsections, and determining a match between the video content and protected video content based at least in part on a comparison of the plurality of signatures to one or more stored signatures generated based on the protected video content.
