Available multicast content can be identified to gateways serving consumption devices, and the gateways can receive requests for unicast content deliver, but honor the requests with multicast group sessions.

Abstract: An apparatus, method, and system are described for transmitting a television program signal. A portion of a local frequency spectrum may be determined to be free, or relatively unused. A user selection of a television program or broadcast programming channel may be received from a program lineup in an electronic programming guide. The selected program may be selected from a gateway, translated, and transmitted over the portion of the frequency spectrum determined to be free. The translation may include converting a signal from the gateway into a National Television Systems Committee (NTSC) signal or a mobile TV signal.

Abstract: Methods, apparatuses, and software are described for implementing dynamic bandwidth load balancing in a data distribution network that provides a plurality of simultaneous video streams over a plurality of channels arranged as a plurality of bonded groups. Various factors may affect the assignment of bonded groups, from initial client device registration through subsequent video stream requests.

Abstract: Signals may be forwarded to a variety of ports for transmission. The signals may be modulated for transmission. The forwarding of signals to ports may be accomplished by forwarding the signals to one or more signal modulators using a processing unit. The mapping of signals to ports may change responsive to a triggering event.

Abstract: Methods and systems for Interference management are described. Methods and systems can be used for minimizing interference among communication and/or electronic devices. Interference data can be gathered/received from interference sources such as weather and natural patterns, various electronic devices, and one or more network protocols. The interference data can be used to generate interference patterns of each interference source in an interference map. The interference map can be used to determine how a particular interference pattern can affect a system. The interference map can also be used to evaluate a new source of interference (e.g., cordless phones, weather conditions) to determine how a system can be affected. The interference data can also be associated with an interference signature (e.g., an interference pattern, a fingerprint) for an interference source in a database. The database can be used based on the interference signature to identify known and/or unknown interference sources.

Abstract: Aspects of the disclosure relate to signal monitoring at edge of a network domain in a network. A monitoring device can evaluate communication quality of information streams in downstream frequency channels, and operation conditions in a telecommunication network. In one aspect, communication quality can be evaluated at the physical layer level or at a higher-layer level containing payload data. In response to an operation issue, the monitoring device can transmit a notification to a node of a distribution platform of the telecommunication network.

Abstract: A hybrid fiber-coax network may replace an analog forward link with a digital optical forward link between a converged cable-access platform (CCAP) and node, which may allow for improved data-throughput rates on the network. Replacing the analog forward link with the digital optical forward link may allow for a greater distance between a headend and the node. Further, the digital optical forward link may improve link modulation error ratio (MER), which, when combined with advanced headend equipment, may enable a cable modem to support the high-order modulation profiles (e.g., profiles included in DOCSIS 3.1).

Abstract: An apparatus, method, and system are provided for combining and processing broadcast and narrowcast content on a common platform. The broadcast and narrowcast content may be processed, routed, encrypted, and transmitted. In some embodiments, a modulator may be used modulate the broadcast content and the output from that modulator may be coupled to an input of one or more interface cards. The inputs of the one or more interface cards may also be coupled to outputs from a plurality of modulators that may be configured to modulate the narrowcast content. In this manner, a reduction in resources may be obtained.

Abstract: A bandwidth allocation and monitoring method may divide available bandwidth on a shared communication medium into a plurality of discrete tones that can be individually allocated to modems on an as-needed basis. The effective modulation rate that a particular modem can use for each discrete tone can be monitored over time using a schedule of pilot tones transmitted from the modems on different tones at different times. The schedule may define representative pilot tones, in which case effective modulation rates for neighboring tones may be inferred from a determined effective modulation rate of a pilot tone.

Abstract: A modem system may include modems that have multiple upstream transmitters for transmitting signals upstream in a communication network. In some embodiments herein, one or more of those upstream transmitters may be retasked to transmit downstream signals for reception at devices within a modem's premises. The downstream signal may be modulated differently from its original modulation as received by the modem, and may be modulated in a manner that can be received by legacy components on the premises, such as analog televisions.
