Aspects of a method and system for content selection, delivery and payment may comprise a management entity that coordinates operation of one or more endpoint devices. The one or more endpoint devices may be operable to select one or more parameters associated with a particular content type from the management entity. The particular content type may specify a type of media content that is handled by the one or more endpoint devices. The one or more endpoint devices may be operable to receive configuration information from the management entity based on the selected one or more parameters associated with the particular content type. The one or more endpoint devices may be configured utilizing the received configuration information. The one or more endpoint devices may be operable to pay for the received configuration information.

Method and system for content selection, delivery and payment

Method and apparatuses are disclosed to substantially compensate for various unwanted interferences and/or distortions within a communications receiver. Each of these apparatuses and methods estimate the various unwanted interferences and/or distortions within the communications receiver. Each of these apparatuses and methods remove the estimates of the various unwanted interferences and/or distortions within the communications receiver from one or more communications signals within the communications receiver to substantially compensate for the various unwanted interferences and/or distortions.

Compensating for unwanted interference in a communications receiver

A method of managing traffic in a communications channel includes the steps of receiving a subscriber ID corresponding to a subscriber, performing a spectral analysis on a signal received from the subscriber within a time interval identified by the subscriber ID, and adjusting transmission characteristics of the subscriber based on the spectral analysis.

Receiver having integrated spectral analysis capability

A transmitter for use in a cable modem termination system includes a data processing module that generates a plurality of OFDM symbols from a data packet. A probe symbol generator generates a probe symbol, as one of a plurality of probe symbol types. The probe symbol is selectively inserted within the plurality of OFDM symbols, at a pre-defined probe symbol interval.

Communication system with proactive network maintenance and methods for use therewith

A communication device is configured to perform symbol mapping of bits to generate modulation symbols using one or more modulations. The device may employ a blended modulation composed of bit labels or symbols having different numbers of bits per symbol and different modulations. For example, the device may symbol map bit labels/symbols having first number of bits per symbol to first modulation, and the device may symbol map labels/symbols having second number of bits per symbol to second modulation. The device may be configured to perform forward error correction (FEC) or error correction code (ECC) and coding of information bits to generate coded bits that subsequently undergo symbol mapping. The device may be configured to operate based on different operational modes based on substantially uniform steps of rates, or bits per symbol, and energy per bit or symbol to noise spectral density ratio (E/Nor E/N).

Fine step blended modulation communications

A communication device (e.g., a cable modem (CM)) includes a digital to analog converter (DAC) and a power amplifier (PA) that generate a signal to be transmitting via a communication interface to another communication device (e.g., cable modem termination system (CMTS)). The CM includes diagnostic analyzer that samples the signal based on a fullband sample capture corresponding to a full bandwidth and/or a subset (e.g., narrowband) sample capture to generate a fullband and/or subset signal capture (e.g., of an upstream (US) communication channel between the CM and the CMTS). The diagnostic analyzer can be configured to generate sample captures of the signal based on any desired parameter(s), condition(s), and/or trigger(s). The CM then transmits the signal to the CMTS and the fullband and/or subset signal capture to the CMTS and/or a proactive network maintenance (PNM) communication device to determine at least one characteristic associated with performance of the US communication channel.

Noise localization within cable based communication systems

Many communication systems operate based on orthogonal frequency division multiplexing (OFDM) signaling and/or orthogonal frequency division multiple access (OFDMA) signaling. Within such systems, narrowband interference, which may alternatively be referred to as narrowband ingress, narrowband ingress interference, narrowband noise, etc., may adversely affect one or more subcarriers or tones causing a reduction in performance or even link failure. Such narrowband interference may affect only one or a relatively few tones employed within such communications. When the narrowband interference is identified, a transmission may then be made including one or more information-free tones. A device that receives such a transmission then uses those information-free tones to reduce or cancel the narrowband interference. Such processing may be performed in the frequency-domain, the time domain, or both.

Interference cancellation within OFDM communications

A method and apparatus is disclosed to determine communications receiver parameters from multiple channels of a received communications signal and to configure and/or adjust communications receiver parameters to acquire one or more channels from among the multiple channels of the received communications signal. A communications receiver observes a multi-channel communication signal as it passes through a communication channel. The communications receiver determines one or more communications receiver parameters from the multiple channels of the received communications signal. The communications receiver configures and/or adjusts communications receiver parameters to acquire the one or more channels from among the multiple channels of the received communications signal.

Communication receiver enhancements using multi-signal capture

A transmitter's operation is characterized using components having relatively low cost and low complexity. A device includes comparator(s) that compare a transmitter's analog output to predetermined level(s) to generate count(s) associated with analog output range bin(s). Each of the predetermined levels is associated with a corresponding one of the analog output range bins. A transfer function of the transmitter is generated using the comparison count values associated with the analog output range bin(s). A histogram may be generated from the comparison count values associated with the various analog output range bins. An equalizer is implemented to process data that will be transmitted by the transmitter. The equalizer uses equalizer parameter(s) that are selected based on the characterization of the transmitter (e.g., its transfer function, its histogram, etc.). The equalizer may use default or start up parameters until the transmitter's operation is characterized.

Broadband amplifier linearization using captured histogram data

One or more processors and/or one or more circuits may be operable to configure one or more virtual machines and a hypervisor for controlling the one or more virtual machines. The virtual machines and the hypervisor may be distributed across a plurality of network devices. A sub-hypervisor may be configured within each of the virtual machines utilizing the hypervisor. Load information of the network devices may be communicated to the hypervisor utilizing the sub-hypervisors. The virtual machines may include threads, may be load balanced utilizing the hypervisor, dynamically configured utilizing the hypervisor based on changes in the network devices, and scaled by the distribution of the virtual machines across the network devices. Information from the processing of data may be received in the virtual machines. The network devices may include a plurality of: servers, switches, routers, racks, blades, mainframes, personal data assistants, smart phones, desktop computers, and/or laptop devices.

An error probability may be determined for said received data and retransmission of portions of said data with error probability above an error threshold may be requested. The variable modulation may include single carrier modulation, orthogonal frequency division modulation, synchronous code division multiple access, and/or from 256 QAM to 2048 QAM or greater. The variable encoding may include forward error correction code, which may include low density parity check code.

Method and system for digital video broadcast for cable (DVB-C2)

A new protocol uses a trigger message to identify one or more symbols transmitted between a first and a second communication device. The first device generates and transmits a trigger message to the second device. This process may be initiated based on the first device receiving a measurement initiation message from another device (e.g., such as the second device or another device within the system). Then, the first device transmits a signal that includes those one or more symbols to the second device. Before or during transmission, the first device generates a first capture of those one or more symbols. After receipt of the transmission from the first device, the second device performs a second capture of those one or more symbols identified within the trigger message. Then, any device having the first and second captures can determine a characterization of the communication pathway between the first and second devices.
