Devices, systems and methods that arrange a plurality of cable modems into one or more clusters so that a plurality of bitloading profiles may be determined, by which data may be communicated to and from the cable modems, after allocating the plurality of the bitloading profiles among the cable modems.

Bitrate optimized clustering for OFDM/OFDMA profile generation

Systems and methods to support switching of virtual cores.

Method to support redundancy switching of virtual MAC cores

Systems and methods for aggregating samples of Proactive Network Maintenance (PNM) data representing state information of a communications network. Each sample may be associated with one of a plurality of different frequency ranges, where the samples are aggregated over a temporal range and aggregated over a frequency range. The data aggregated in this manner may then be used to configure the network.

Data aggregation for communications network optimization

Systems and methods to support flexible scaling and dynamic resource allocation for virtualized cable data plane applications. The system includes a head end together with a node to provide data to customer devices. A container operating that includes a data plane application that provides packets of data for transmission to the node. The data plane application is instantiated with at least one of a virtual networking function and a computing resource function.

Automated lifecycle management with flexible scaling and dynamic resource allocation for virtualized cable data plane applications

A cable distribution system includes a head end connected to a plurality of customer devices through a transmission network that includes a remote fiber node that converts digital data to analog data suitable for the plurality of customer devices, where the head end includes at least one server each of which includes a respective processor.

Availability and redundancy for vCores

A system includes vCores and a messaging system to receive IPDR data. The IPDR data from the messaging system is transmitted by an IPDR exporter to an IPDR collector.

IPDR communication system for virtualized core sources

Systems and methods for managing interference groups in a full duplex transmission network.

Systems and methods for sounding in a full duplex CATV architecture

In one embodiment, a head end is connected to a plurality of customer devices through a transmission network includes a remote fiber node that converts received data to analog data suitable to be provided on a coaxial cable for the plurality of customer devices. The head end includes vCore instantiated on one of the servers of the head end configured to provide services to the plurality of customer devices through the transmission network.

Management system for vCores

Systems and methods for analyzing network parameters in a data communications network so as to maintain a desired Quality of Experience (QoE) of at least one subscriber.

QoE-based CATV network capacity planning and upgrade system

Systems and methods can operate to deliver video information over IP networks on a best-effort basis. Best-effort implies that information is delivered without any guaranteed quality of service. During the encoding of video transport streams into video frames, a decoding time stamp (DTS) can be generated that can be used by a video decoder to determine when to begin decoding the video frame data. Information from one or more video frames can be encapsulated in an IP packet. Using the DTS, video encoding rate and video frame size, a time constraint value can be calculated and can provide an indication of the relative transmission priority for the best-effort IP delivery of IP packets containing encapsulated video information.

Video delivery over IP packet networks

Systems, apparatus and methods can operate to generate frame aligned digital video streams encoded at different bitrates from a common digital video stream. To provide uninterrupted playback of video content when a device switches from one stream encoded at one bit rate to the same digital video stream encoded at another bitrate, the video frames of the digital video streams can be aligned. To provide for proper frame alignment between fragments representing the same frame of a digital video stream encoded at different bitrates, video encoding device(s) can mark decoded digital pictures for subsequent encoding at different bit rates when the division of a program reference clock value by the fragment period approaches an integer value.

Video frame alignment in adaptive bitrate streaming

This disclosure describes cooperatively transcoding an input signal to one or more output signals. The software and/or hardware logic modules are designed to work cooperatively in ways that can reduce the number and/or complexity of logic modules implementing a plurality of related transcodings of signal formats. By advantageously determining dependencies and sub-functions in transcoding an input stream to multiple output streams, hardware and/or software logic can be reduced. Reduced logic to implement multi-format transcoding improves the costs and/or capacity of systems for transcoding large numbers of streams and signals.

Cooperative transcoding to multiple streams

Systems and methods of this disclosure can operate to provide audio level normalization in multimedia streams. In some implementations, audio level normalization can include partially decoding audio frames included in a multimedia stream, calculating an average energy level of the partially decoded frames, comparing the average energy level of the partially decoded frames to a nominal energy level, modifying a dialnorm setting associated with the multimedia stream, and reencoding the partially decoded audio frames for inclusion as a modified audio stream corresponding to the video stream.
