A communication device (alternatively, device) includes a processor configured to support communications with other communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other communication device(s) and to generate and process signals for such communications. Such a communication device includes a processor configured to perform codeword builder functionality to generate information that undergoes error checking and correction (ECC) and/or forward error correction (FEC) coding. The processor intelligently selects packets from buffers to generate information blocks that undergo ECC and/or FEC coding and transmission and to meet certain latency constraints in conjunction with a predetermined period of time (e.g., a programmable threshold). Such a communication device may be implemented in a point-to-multipoint communication system that services multiple other communication devices.

Embodiments of a digital up-converter and an N-channel modulator are provided herein. The embodiments of the digital up-converter, in combination with the N-channel modulator, are capable of efficiently filling the spectrum of one or more RF signals with one or more types of information signals. For example, the digital up-converter can fill the spectrum of one or more RF signals with both broadcast and narrowcast video and data signals. In addition, the digital up-converter is capable of flexibly mapping the information signals to one or more channels of the one or more RF signals using a novel, three-level switching architecture.

A system and method demodulate N QAM signals (N being a positive integer equal to or greater than 1) substantially simultaneously using, for example, one or two oscillators, regardless of how many QAM signals need to be demodulated.

System and method for demodulating multiple QAM signals

A network monitor includes means for monitoring downstream traffic from a cable modem termination system (CMTS) to a cable modem (CM), means for monitoring upstream traffic from the CM to the CMTS, and means for identifying a data format used by the CMTS and the CM for bi-directional communication.
