  • Patent number: 8189553
    Abstract: A method of encapsulating TDM data into individual data packets for transmission across a packet network includes delineating the TDM data into one or more signaling multiframes, wherein each signaling multiframe includes one period of a periodic signaling pattern. The method also includes appending a header that is associated with the individual data packets to each of the signaling multiframes of TDM data. Further, a method of selecting the number of multiframes of TDM data in the data packet includes calculating the efficiency of the data packet as a function of the number of multiframes, and selecting the number of multiframes so that the efficiency of the data packet increases exponentially as a number of time-slots in the TDM data increases.

  • Patent number: 8160068
    Abstract: A system and method for facilitating communication between a CMTS and a VoIP application server in a cable network. VoIP-enabled customer premises equipment (CPE) generates packets that are sent through a cable modem (CM) to a cable modem termination system (CMTS). A packet is parsed by CMTS and the destination IP address and port number compared to the destination IP address-port tuples received by the CMTS from a datastore. A packet that is directed to an IP address-port tuple on the target list (a “service request packet”) is modified to incorporate CMTS-identifying information and subscriber-identifying information in the packet header. When the VoIP application server communicates with the CMTS to reserve the network resources, the VoIP application server provides the CMTS with the CM MAC and CM IP addresses to facilitate resource allocation, subscriber identification and billing.

  • Patent number: 8155202
    Abstract: A scrolling encoder encodes scrolling elements that are to be scrolled around all or a subset of the frames of a video stream or file with their movement in time and space controlled by a path to produce a video stream or file, without searching previous or subsequent frames of the video stream or file for reference blocks. The scrolling element can be an image, video, text or any combination thereof. The scrolling element is encoded using information about the contents of the scrolling element and information about a path the scrolling element is to take across a screen. The information about the contents of the scrolling element is obtained when the scrolling element is first introduced into a frame. The information about the path of the scrolling element is provided by an external component or is otherwise deduced. Optionally, the path information includes information about how the scrolling element is to change appearance. This information may be used to automatically generate error terms.

  • Patent number: 8072977
    Abstract: An approach is provided for managing network resources and policies. A network resource manager receives an allocation request, over a radio network, for one or more network resources for joining one of a plurality of multicast groups, the one mutlicast group being associated with a quality of service (QoS) level. The network resource manager then determines whether the network can accommodate the allocation request and modifies the network to accommodate the allocation request based on the determination by modifying a local multicast service provider (LMSP) mapping list that associates, respectively, one or more LMSPs with the multicast groups.

  • Patent number: 8064364
    Abstract: Performance data relating to each of multiple network devices distributed in a geographic region is analyzed. That data can include values for various parameters measured automatically by routine polling of subscriber devices and/or network elements serving those subscriber devices. Measured parameter values can then be stored in a database and made available, together with information about subscriber device locations, to one or more analysis servers that analyze different portions of the network. As part of that analysis, groups of devices experiencing performance problems are identified based on device location. Information about those groups is then communicated and can be made available for, e.g., monitoring by service personnel.
