  • Publication number: 20120072962
    Abstract: A method for redirecting video content includes receiving a video signal at the set-top box and decoding the video signal to produce unrendered video data. The unrendered video data is encoded and provided to the remote device via a wide area network. By encoding unrendered, rather than rendered, video data for transmission to the remote device, the need for an encoding device external to the set-top box is obviated.

  • Publication number: 20090172767
    Abstract: A system and method is disclosed for restricting a remote control interface port of a set-top box configured to broadcast multimedia programs over a provider network. A change schedule that changes communication parameters may restrict the remote control interface port. The operating frequency or the code set used to transmit data and commands may be changed at random or at predefined intervals. The set-top box, the remote control, or an external network device may initiate the change schedule. Encryption of communications between the set-top box and the remote control unit may also be performed to protect the set-top box from unauthorized access.

  • Publication number: 20080198754
    Abstract: A multicast test of an Internet Protocol (IP) network is performed with an initial multicast probing frequency. The multicast probing frequency of the multicast test is increased, and an impairment of the IP network based on the multicast test is detected based on the multicast test. Based on detecting the impairment, a unicast test is performed at one or more segments of the IP network. Based on the unicast test, an impaired segment of the IP network is identified.
