  • Patent number: 11044119
    Abstract: A router device in a subscriber domain receives communications from a communication device. The communications are destined for delivery over a first network operated by a corresponding service provider to a destination in a second network such as the Internet. To convey communications, the router device maps a network address obtained from the first communications to a corresponding marker assigned to the communication device. The router device then tags the communications from the communication device with the corresponding marker and forwards the tagged communications (with the marker) over the first network to the second network. The first network operated by the service provider conveys the tagged communications in accordance with a data delivery policy as indicated by the corresponding marker in the forwarded communications.

  • Patent number: 9736511
    Abstract: Particular embodiments use a network device, such as a gateway, as an interface between a first network, such as a hybrid fiber coax (HFC) network, and a second network, such as a home network. The first network includes a frequency spectrum that may be considered “high split”, and the second network has a frequency split that is used by legacy set-top box boxes. A head-end sends a network downstream signal that includes the out of band downstream signal in the downstream frequency band using the HFC network's frequency split. The out of band downstream signal may be represented by digital data. The gateway can then determine samples from the digital data, which are then used to reproduce the out of band downstream signal at the desired frequency for the home network. That is, the out of band downstream signal may be recreated in the frequency range of 70-130 MHz.

    Abstract: Distributed CMTS device for a HFC CATV network serving multiple neighborhoods by multiple individual cables, in which at least some and often all of the QAM modulators that provide data for the individual cables are remote QAM modulators ideally located at the fiber nodes. A CCAP set of IP/on-demand data is transmitted to the nodes using an optical fiber, often using digital protocols such as Ethernet protocols. Optionally a basic set of legacy CATV QAM data, transmitted using RF waveforms transposed to optical frequencies, may also be transmitted to the nodes using either the same or different optical fiber. The nodes extract the data specific to each neighborhood, and inject this data into unused cable QAM channels along with any optional legacy CATV QAM waveforms as desired, thus achieving improved data transmission rates through finer granularity.

A cancellation circuit is coupled to the forward pathway and the return pathway. The cancellation circuit separates and isolates the forward signal from the return signal.

  • Patent number: 9602775
    Abstract: A system and method for the automatic discovery and provisioning of a video set top box within an IPTV network is provided. When first connected to a residential gateway, the set top box requests the address information of the residential gateway. The set top box then sends a request to a video operations and support server (VOSS) with the identifying information for the set top box and the residential gateway. Once the VOSS determines that the residential gateway is authorized for video service, the VOSS associates the residential gateway with the set top box. The VOSS then communicates the authorization to a middleware server, which downloads client software and encryption keys to the set top box, enabling the set top box to request and receive video content. The set top box may be reconnected to any port on the residential gateway and receive video service without being re-provisioned.

  • Patent number: 9584869
    Abstract: Distributed and software reconfigurable remote CMTS (CMRTS) device, based on MAC and PHY units with FPGA and DSP components, for a HFC CATV network. The various CATV RF modulators, such as QAM modulators, may be located entirely at the fiber nodes if desired. Although a basic set of CATV QAM data waveforms may optionally be transmitted to the nodes using a first fiber, in a preferred embodiment, all data may be transmitted to the nodes using other protocols such as Ethernet protocols. The nodes will extract the data specific to each neighborhood and inject this data into the cable portion of the system as RF waveforms, such as RF QAM channels. A computerized “virtual shelf” control system for managing and reconfiguring the FPGA and DSP based CMTRS units, as well as a new type of edge router based all-digital virtual head end (virtual converged cable access platform) is also disclosed.

  • Patent number: 9451655
    Abstract: An apparatus includes a first port and a second port operably coupled to a format conversion module each of which is at least partially disposed within a housing. The first port is operably coupled to a cable configured to transfer a first data unit having a first format associated with a first communication medium to the first port. The format conversion module receives the first data unit from the first port and converts the first data unit from the first format to a second format associated with a second communication medium to produce a second data unit. The second port is operably coupled to a wireless access point that is physically distinct from the housing. The second port is configured to receive the second data unit and send the second data unit to the wireless access point.

    Abstract: A method for presenting a custom content in a set top box and a set top box are disclosed. The method includes checking a display cache and a flash memory of a set top box after the set top box is powered on, writing a custom content in the flash memory into the display cache if the display cache and the flash memory of the set top box are checked correct, controlling the custom content written into the display cache to be presented to a user on a video terminal, and, after the custom content written into the display cache is controlled to be presented to the user on the video terminal, checking a hardware device other than the display cache and the flash memory in the set top box, starting an operating system of the set top box, and performing network authentication.

  • Patent number: 9325515
    Abstract: Distributed CMTS device for a HFC CATV network serving multiple neighborhoods by multiple individual cables, in which at least some and often all of the QAM modulators that provide data for the individual cables are remote QAM modulators ideally located at the fiber nodes. A CCAP set of IP/on-demand data is transmitted to the nodes using an optical fiber, often using digital protocols such as Ethernet protocols. Optionally a basic set of legacy CATV QAM data, transmitted using RF waveforms transposed to optical frequencies, may also be transmitted to the nodes using either the same or different optical fiber. The nodes extract the data specific to each neighborhood, and inject this data into unused cable QAM channels along with any optional legacy CATV QAM waveforms as desired, thus achieving improved data transmission rates through finer granularity. A computerized “virtual shelf” control system for this system is also disclosed.

  • Patent number: 9298732
    Abstract: Embodiments relate to searching a cloud-based file storage system using a set of expandable probes. Platforms and techniques are provided to search for a file whose location in cloud storage resources is recorded in a consistent hash ring structure. In a hash ring, a file name can generate a hash output corresponding to a position around a circle. The closest clockwise node to that location can contain the file itself, or a link to another location containing or leading to the file. When a link has become obsolete and no longer points to the file, it may be necessary to search for that file. Embodiments perform a graduated search for the missing file, starting one node from the original node, then trying two adjacent nodes, then four adjacent nodes and so forth in expanding fashion, until the file is found or the hash structure is exhausted.

  • Patent number: 9270472
    Abstract: A system and method for assigning a service flow classifier to a device. A MAC address of a device is extracted from a DHCP discover message. A DHCP server constructs a key from the device MAC address and an IP address assigned by the DHCP server. The key identifies a record of attributes of the device. A configuration server uses the key to access the attribute record and to generate a boot file for the device. The boot file includes one or more service flow classifiers that determine a service flow for packets destined for the device.
