    Abstract: A multimode battery charger circuit supporting switch mode and linear mode charging operations. In various embodiments, the multimode battery charging circuit includes mode control circuitry, a linear gate driver, a pulse width modulation (PWM) control circuit, a programmable constant current control loop circuit, and a programmable constant voltage control loop circuit. In operation, the mode control circuitry receives a charge mode indication signal corresponding to a desired charge mode. Based on this signal, the mode control circuitry enables either the linear gate driver or PWM control circuit to provide control signals to output transistors coupled between an adapter power port and a battery pack, thereby supporting a plurality of charging modes. In some embodiments, one or more of the output transistors are formed on a common substrate with the multimode battery charger circuit.

    Abstract: 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.

    Abstract: A device and method for providing an adaptive bit rate (ABR) proxy is disclosed. An ABR proxy determines an optimal data format to receive content segments for an audio/video (AV) content item from a source ABR server, and generates, based on that format and/or current network conditions, one or more local AV representations for providing content segments for the AV content item to locally connected devices. A local client device selects a local AV representation, and the ABR proxy provides the content segments for the AV content item to the local device in accordance with the selected local AV representation.

    Abstract: An outer encoder encodes input data signal to generate a first encoded signal. An inner encoder encodes a subset of the input data to generate a second encoded signal, wherein the inner encoder has a different forward error correction (FEC) than the outer encoder. A symbol mapper processes the first encoded signal and the second encoded signal to generate a sequence of discrete-valued modulation symbols.
