Systems and methods for changing broadcast channels using channel change requests to, and channel change responses from, an SDV server. In some embodiments, the channel change request is made after determining that broadcast tuning parameters are otherwise not available from memory and/or a broadcast system.

Distributed and highly software reconfigurable 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 divided between QAM modulators located at the cable plant, and remote QAM modulators ideally located at the fiber nodes. A basic set of CATV QAM data waveforms may optionally be transmitted to the nodes using a first fiber, and a second set of IP/on-demand data may be transmitted to the nodes using an alternate fiber or alternate fiber frequency, and optionally using other protocols such as Ethernet protocols. The nodes will extract the data specific to each neighborhood and inject this data into unused QAM channels, thus achieving improved data transmission rates through finer granularity. A computerized “virtual shelf” control system for managing and reconfiguring the FPGA and DSP based CMTRS units is also disclosed.

At least one aspect is directed to managing policies to control network assets in real-time by dynamically enforcing policies based on a variety of detected conditions including service quality, subscriber usage, network performance, bandwidth, and events. The systems and methods described herein can enforce policy actions using the PacketCable Multimedia (PCMM) protocol, which is supported by Cable Modem Termination Systems (CMTS). The present solution can monitor IPDR usage data and SNMP network utilization data to determine conditions about the network and provide PCMM instructions to a CMTS to control network resources on an individual subscriber level. By providing PCMM instructions to a CMTS, the present solution can make service changes to individual modems without modifying the modem's configuration file, requiring a modem reboot, or the installation of additional hardware in the operator's network.

An integrated network receiver includes a first universal resource identifier for a first channel and an input suitable for receiving a first input video content from the Internet based upon the first universal resource identifier. The integrated network receiver provides the first input video content for the first channel to a head end connected to a plurality of customer devices through a transmission network. The integrated network receiver updating the first universal resource identifier based upon data obtained from a video address server.

Premises apparatus and methods for providing aggregated high-bandwidth, low-latency, data service over a content delivery network including existing wireline infrastructure. In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 3GPP and IEEE Std. 802.11 services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Premises apparatus are used to support multi-service integration (e.g., aggregation of mobile wireless, premises, and other services), as well as incipient IoT applications and technologies.

Methods and apparatus for enhancing connectivity for a device backhauled by a wireline communication network. In one embodiment, the device comprises a small-cell or other wireless base station that is backhauled by a DOCSIS system within a managed HFC network, and the method and apparatus enable enhanced connection of user devices serviced by the base station (such as 3GPP UE or CBRS FWA) to a core entity for e.g., authentication and packet session establishment. In one implementation, enhanced Cable Termination System (CMTS) and cable modem (CM) devices coordinate to allocate prioritized service flows to traffic sourced from the base station. These service flows can selectively bypass extant DOCSIS protocols which might otherwise increase connection latency (including connection failure) such as AQM (active queue management) and packet dropping algorithms. In some variants, upstream service flow data rates can also be enhanced through temporary utilization of higher-order modulation and/or coding schemes.

A distributed CATV system capable of removing jitter of upstream IP packets from distribution nodes over a packet distribution network is described. The headend of the CATV system has a jitter buffer that temporarily stores each upstream packet until a scheduled time that is computed to equalize the delays among the different distribution nodes. Each packet is associated with a timestamp, and the scheduled time to remove the packet from the jitter buffer is computed based on the packet's timestamp and the equalized delay. The distribution node that sends the packet upstream to the headened also inserts the timestamp into the packet.

A network element of a cable television (CATV) network, comprising one or more amplifier units for amplifying downstream signal transmission into one or more output channels; a temperature sensor configured to detect one or more of the following: ambient temperature of the network element, and/or one or more of components of the network element; a memory configured to store a predetermined correlation between the detected ambient temperature and a corresponding correction of a bias current for said one or more amplifier units; and a processing unit configured to control the bias current of said one or more amplifier units to be adjusted based on the predetermined correlation.

The present disclosure describes a monitoring device for determining one or more characteristics of one or more scheduled programs within one or more packetized elementary streams of one or more transport streams. The monitoring device receives the one or more transport streams from a service provider system and de-encapsulates the one or more packetized elementary streams from the one or more transport streams. The monitoring device determines the one or more characteristics of the one or more scheduled programs from the one or more packetized elementary streams. The one or more characteristics can be used by the monitoring device to adapt on a dynamic, real-time, or near real-time, basis to changes to the one or more transport streams.

The apparatus or device for the cable modem comprises interface circuitry/communication means for communicating with transceiver circuitry/transceiving means of the cable modem, and processing circuitry/processing means. The processing circuitry/means is configured to determine information on a power level of received transmissions at a plurality of points in time in a plurality of frequency bands of an upstream spectrum via the transceiver circuitry, to determine, for each of the plurality of frequency bands, numeric information on an occurrence of one or more power levels of the received transmissions in the respective frequency band, and aggregate the numeric information on the occurrence of the one or more power levels of the received transmissions by frequency band.
