  • Publication number: 20120079554
    Abstract: A system for providing television (TV) service including high definition television (HDTV) service, and for providing verification that a subscriber has connected an HDTV to the system includes a TV service provider headend and a set top box (STB). The HDTV may have an HDTV digital video interface (DVI) interconnect. The STB may be electrically coupled to the headend and have an STB DVI interconnect. When the HDTV DVI interconnect is initially electrically coupled to the STB DVI interconnect, the HDTV generally presents a data signal to the STB and the STB generally presents the data signal to the headend.

  • Publication number: 20120047196
    Abstract: A media server is hosted in a service provider's network so that media content can be stored from or rendered to a private network such as a Digital Living Network Alliance (DLNA) network. Media content may be stored directly by accessing the media server or by downloading the media content to the media server. A server platform may support a set of media servers, where each media server is connected to a corresponding DLNA network. A multicast group may be established among the set of media servers so that media content may be shared with members of the multicast group. Media content may be aggregated for media content for the multicast group based on content characteristics, where the content characteristics are indicative of media content that can be shared with members of the multicast group.

  • Patent number: 8121033
    Abstract: A method of traffic regulation in a packet communication network involves a token bucket associated with a subscriber. Packets arriving at the regulator are handled in accordance with the token bucket configuration. The method involves measuring a demand placed on the network by the subscriber. The token bucket configuration is dynamically adjusted based on the demand. Another method of traffic regulation handles packets arriving at the regulator in accordance with first and second token bucket configurations. The first token bucket regulates packet rate while the second token bucket regulates data rate. Another method of traffic regulation involves handling packets in accordance with a token bucket configuration, where the amount of tokens to be removed is based on the amount of the flow and is further based on a classification of the flow. Packet-level devices for traffic regulation are also contemplated.

  • Publication number: 20120036184
    Abstract: Automated booting of a client for a subscriber is provided for clients that are for use in interactive user sessions that involve multimedia. A subscribe message is sent from the client to a proxy server. The proxy server authenticates the subscribe message, and sends the subscribe message to the configuration server. A notify message is sent to the client from the configuration server. The notify message is sent through the proxy server, and contains a location of a profile for the client. The profile is downloaded to the clients. This arrangement allows the persistence of profiles in a centralized place.

  • Publication number: 20120017234
    Abstract: A method of initializing, provisioning, and managing a cable modem and a customer premise equipment device includes, prior to receiving the configuration file for the cable modem, providing an equipment identification message containing a description of the customer premise equipment device connected to the cable modem. In the case where the cable modem has yet to be provisioned, the configuration file received from the network server is a particular access-limiting configuration file that is selected from a group of access-limiting configuration files. The selection of the particular access-limiting configuration file is based on the description of the customer premise equipment device in the equipment identification message. This allows different devices to have different network restrictions or different walled gardens.

  • Publication number: 20120013443
    Abstract: A security system that can be used in a home, office, or other building in order to generate alarms or take other actions depending on conditions within the building. The security system may rely on sensors within the building which sense various conditions and collect other data. The information learned from the sensors can be communicated to a location outside the building for processing, such as, but not limited to, processing associated with a need to instigate an alarm.

  • Patent number: 8099508
    Abstract: Tokens and policy descriptors are used for dynamic on demand session management in a distributed and scalable architecture for on demand sessions and resource management. The architecture includes an on demand client, a purchase server, and a session manager. A purchase token is generated at the purchase server and assigned to the on demand client. The purchase token represents at least one requested asset. In response to an on demand session set-up request corresponding to the purchase token from the on demand client to the session manager, the purchase token is expanded to generate at least one dynamic policy management descriptor for the on demand session. This provides token-based purchase authorization and policy management for on demand services.

  • Publication number: 20110228942
    Abstract: A controller receives an encrypted media stream (“EMS”) and an identifier indicative of a selected content key from a headend. The EMS is encrypted with an encryption key and can be decrypted with a corresponding decryption key which is determinable from the selected content key. The controller receives indexes and content keys from the headend prior to receiving the EMS. Each index respectively corresponds to an identifier with one index corresponding to the identifier indicative of the selected content key. The content keys correspond to the indexes with one content key corresponding to the index corresponding to the identifier indicative of the selected content key. The controller selects the index corresponding to the identifier indicative of the selected content key upon receiving the EMS, determines the selected content key from the selected index, determines the decryption key from the selected content key, and decrypts the EMS with the decryption key.
