  • Patent number: 8863217
    Abstract: A device for and a method of decreasing the data rate of a digital return path link in a Cable Television Hybrid Fiber-Coax system (CATV system) is disclosed. At the node of the CATV system, the bandwidth of the a digital data stream representative of an analog return signal is limited to a desired frequency band. The bandwidth-limited data stream is then digitally re-sampled at a predetermined multiple of a center frequency of the frequency band. The re-sampled data stream is then separated into two data streams. Then, these separate data streams are digitally decimated to a lower data rate, interleaved and serialized for transmission to a head end of the CATV system. A reverse process reconstructs the original analog return signal's signal components within the desired frequency band at the head end.

  • Patent number: 8826359
    Abstract: System and method to extend the upstream data capacity of an HFC CATV system by extending a “shadow” optical fiber network deeper into the various CATV cable neighborhoods, with coax fiber terminals (CFT) spaced roughly according to the distribution of CATV active devices such as RF amplifiers. The CFT can intercept local upstream data from various neighborhood sub-regions and transform this upstream data into upstream optical data, thus relieving upstream data congestion in the 5-42 MHz CATV frequency region. The system can produce an order of magnitude improvement in upstream capability, while maintaining high compatibility with legacy HFC equipment. The CFT may exist in multiple embodiments ranging from low-cost “dumb” CFT to sophisticated CFT that can additionally provide GigE to the home (GTTH) service. Methods to maintain good compatibility with legacy CMTS devices, and methods to utilize DOCSIS MAP data for more efficient data transmission are also discussed.

  • Patent number: 8806559
    Abstract: Methods for reducing ingress in a neighborhood node of a cable communication system. The node includes an RF hardline coaxial cable plant and multiple subscriber service drops to convey upstream information from multiple subscriber premises over an upstream path bandwidth. A test signal having a frequency falling within the upstream path bandwidth is transmitted proximate to one or more potential points of ingress into the hardline cable plant. Based on signal amplitudes at the test signal frequency representing test signal ingress into the hardline cable plant, one or more faults in the hardline cable plant are specifically identified and remediated so as to significantly reduce a noise power in the node in at least a portion of the upstream path bandwidth below approximately 20 MHz. In one example, hardline plant-related and/or subscriber-related faults are remediated so as to significantly reduce ingress arising from terrestrial short wave radio signals.

    Abstract: A reduced-memory vectored DSL system includes methods and apparatus for reducing the bandwidth and memory storage demands on a vectored DSL system in which FEXT data is transmitted and stored. An upstream-end device such as a DSLAM communicates with a plurality of downstream-end devices such as CPE modems. When test signal data, such as training and/or tracking data, is sent to determine FEXT characteristics of the DSL system, error signals are available for all or substantially all of the upstream and/or downstream frequency band DSL tones used in the system. Dividing a frequency band into sub-bands, only a subset of tones in each sub-band is used for deriving FEXT data, such as a FEXT channel response, FEXT channel coefficients and/or FEXT cancellation coefficients. For tones in the sub-band subsets, full-precision FEXT data values can be derived. For other tones, approximations of the FEXT data can be derived.

  • Publication number: 20130160068
    Abstract: A digital transmitter includes a generic adaptable reconfigurable digital transmitter module; and a reversibly removable module operationally coupled to the generic adaptable reconfigurable digital transmitter module. Configuring a generic adaptable reconfigurable digital receiver having a programmable signal conditioner includes specifying a number of output RF channels; specifying an RF bandwidth of an output channel; and selecting a digital to analog sampling rate of a digital to analog convertor of the programmable signal conditioner as a function of the RF bandwidth of the output channel using a processor/demux of the generic adaptable reconfigurable digital receiver.

  • Patent number: 8464301
    Abstract: An upstream bandwidth conditioning premise device for use as part of a CATV system and for placement on or near a user's premise to reduce noise created on the user's premise that would otherwise be injected into upstream transmission channels and passed into an RF main signal distribution system of the CATV system. The device includes a variable attenuation device, a signal measurement circuit, a memory circuit and an electronic circuit, which is configured to iteratively determine (i) whether an incremental amount of additional attenuation is to be applied and (ii) whether at least a portion of a previously applied incremental amount of attenuation is to be removed. The electronic circuit includes a counting circuit, a threshold comparison circuit configured to compare a peak signal strength to a predetermined threshold, and a peak comparison circuit configured to compare a contemporary peak signal strength to a previous peak signal strength.

  • Patent number: 8458759
    Abstract: A system for locating an impairment in a coaxial cable network comprises an encoder, an impairment detector, and a decoder. The encoder couples to the network at a predetermined encoding point, upstream of the impairment. The encoder automatically encodes an identification code on a signal originating downstream of the encoding point and associated with the impairment. The impairment detector couples to the network at an access point, upstream from the encoding point, and receives signals from the network. The detector is adapted to detect from the received signals the signal associated with the impairment and generate a detected version of the signal. The decoder is adapted to decode the identification code from the detected version of the impairment signal. Once the identification code is determined, the encoder and encoding point are identified, and the location of the impairment is determine to be downstream of the encoding point.

  • Patent number: 8370889
    Abstract: Systems and methods are disclosed for enabling a switched digital video (SDV) client to intelligently generate and transmit reverse request in a SDV system. In this manner, reverse channel traffic is reduced. During rapid channel changes using the up and down keys on a remote control, the SDV client waits a predetermined amount of time before generating a reverse request that is subsequently transmitted upstream to a headend server. By way of example, changing broadcasted channels quickly will not generate a reverse request until the predetermined amount of time is over. In the event that a changed channel is an SDV session, a program select request is immediately generated in order to begin receiving the SDV session.

  • Patent number: 8370886
    Abstract: Provided is a device for use with a headend, a household and an amplifier. The headend is able to provide signals within a high-frequency band fH. The household is able to provide signals within a low-frequency band fL, and to provide signals within a super-high-frequency band fR, where fL<fH<fR. The device includes a splitter, a diplexer and a combiner. The splitter is arranged to receive the signals within the high-frequency band fH and to split the signals within the high-frequency band fH into a first signal portion within the high-frequency band fH and a second signal portion within the high-frequency band fH. The diplexer is operable to pass the second signal portion within the high-frequency band fH to the household, to pass the signals within the low-frequency band fL to the splitter and to pass the signals within the super-high-frequency band fR.
