  • Patent number: 9038119
    Abstract: A handheld leakage detector for finding digital signal leaks in a HFC network, comprises a radio receiver, a leakage receiver, leakage sampler, a correlator, and a display. The radio receiver receives samples of the digital signal taken from the HFC network, called “reference samples.” The leakage receiver receives a leakage signal, which is a leaked version of the digital signal from the HFC network. The leakage sampler samples the leakage signal to form leakage samples. The correlator performs a cross-correlation of the reference samples and the leakage samples, to produce a correlation function. An optimizable value is determined from the correlation function. The value generally becomes more optimized as the detector approaches the leak. The leak is sought by iteratively changing the position of the detector until the value becomes substantially optimized or the leak is found.

    Abstract: “Cradle-to-grave” treatment of leaks begins with technicians logging leakage signal strengths and GPS latitude and longitude coordinates in technicians' vehicles as the technicians go about their daily assignments. Leakage signal strengths and GPS latitude and longitude coordinates are then uploaded to a leakage server. The server calculates leak latitude and longitude coordinates and signal strengths. The system sends the leakage signal strengths and/or calculated leak latitude and longitude coordinates to technicians' vehicles, for example, as components of, or attachments to, work orders. The latitudes and longitudes are converted by GPS navigators in the technicians' vehicles to turn-by-turn directions to the calculated leak locations. The technicians drive to the leaks, identify and repair them, and close the work orders.

  • Publication number: 20150020129
    Abstract: A dual-port testing apparatus is provided for testing a cable network at two test points. The testing may comprise demodulation of a same data packet at the test points, decoding the data packet, performing spectral analysis of the signal, etc. Testing results may be correlated with one another, both visually and by using pre-defined test metrics comprising a weighted sum of demodulation and decoding parameters such as modulation extinction ratio and a codeword error.

  • Publication number: 20150020128
    Abstract: Non-disruptive sweep measurements using low power coherent signals overcome the limitations of prior art frequency response systems for cable networks. Modulated or unmodulated, e.g. continuous wave (CW), test signals are transmitted into the network at a first or input point (input point is in the head end for forward sweep; input point is in the field for reverse sweep). The test signals are transmitted continuously at multiple frequencies, so as a composite they form a wideband, OFDM-like (orthogonal frequency-division multiplexing) waveform. A receiver at a second or output point generates power reading measurements, from which the frequency response of the network is produced.

  • Patent number: 8931023
    Abstract: An approach for providing feedback based on monitoring of channels at a customer premise is described. A digital signal representing a plurality of channels transported over a media broadcast network is received at a set-top box apparatus. A determination of whether one of the plurality of channels satisfies a predetermined criterion relating to performance of the media broadcast network is performed. A network feedback signal based on the determination is generated, at the set-top box apparatus, for transmission to a network monitoring node of the media broadcast network.

  • Patent number: 8931022
    Abstract: A user may purchase in a retail outlet a host device for receiving cable services. The cable operator needs to provide a point-of-deployment (POD) module for insertion into the host device to realize out-of-band communications, and provide conditional access to premium subscription channels. Security measures are implemented to detect removal of the host device from its connection to a broadband communications system. If its removal is unauthorized, the service area in which the host device is located may be identified when it is reconnected to the system. In addition, a transmission device in the host device may be activated to transmit detectable signals to help recover the host device.

  • Patent number: 8904460
    Abstract: A leak defined by coordinates is located in a network. A signal emitted from the leak is detected at first, second and third points having first, second and third sets of coordinates, respectively. Propagation delays t1, t2 and t3 of the signal are measured, which include the propagation delays between the leak and the first, second and third points, respectively. The time difference ?t12 between delays t1 and t2 and the time difference ?t23 between delays t2 and t3 are calculated. The approximate location of the leak is determined by solving for the coordinates of the leak in at least two hyperbolic equations, where the equations are defined by the time differences ?t12 and ?t23, and by the first, second and third sets of coordinates.

  • Patent number: 8898688
    Abstract: The invention provides systems and methods to identify local market media content utilizing a disturbed system and to determine what additional content is relevant in a self-aware, automatic way. A central location stores identification information and related content so in the future it is available if and when another user watches the same content. Therefore, the next time local market media content is played, it can be identified and additional related content can be quickly (e.g. in real time) made available.

  • Patent number: 8898714
    Abstract: Systems and methods for identifying which video segment is being displayed on a screen of a television system. The video segment is identified by deriving data from the television signals, the derived data being indicative of the video segment being displayed on the screen. This feature can be used to extract a viewer's reaction (such as changing the channel) to a specific video segment (such as an advertisement) and reporting the extracted information as metrics. The systems and methods may further provide contextually targeted content to the television system. The contextual targeting is based on not only identification of the video segment being displayed, but also a determination concerning the playing time or offset time of the particular portion of the video segment being currently displayed.

    Abstract: The invention relates to a method of determining maintenance priority for different portions of a CATV network. By calculating a health score for each node of the network based on a plurality of measurements performed downstream from the nodes, the nodes and the downstream segments of the network may be ranked according to their health score values, and the maintenance of the network segments may be prioritized based on the health ranking of the corresponding nodes. The health score for a node may be computed based on a plurality of tilt- and modulation-normalized frequency scans of the network signal.

  • Patent number: 8872978
    Abstract: Provided herein are methods and systems that provide automatic compensation for frequency attenuation of a video signal transmitted over a cable. In accordance with an embodiment, a system includes an equalizer and a compensation controller. The equalizer receives a video signal that was transmitted over a cable, provides compensation for frequency attenuation that occurred during the transmission over the cable, and outputs a compensated video signal. The compensation controller automatically adjusts the compensation provided by the equalizer based on comparisons of one or more portions of the compensated video signal to one or more reference voltage levels. One or more values indicative of one or more levels of compensation provided by the equalizer are stored in memory and/or registers for each time, of a plurality of times. A monitor monitors for changes in the cable and/or the video signal transmitted over the cable based on the stored values.
