Abstract: A video- and/or audio-enabled communication system includes a processor, coupled with a camera, the camera acquiring an image of an object of interest during a video communication session involving multiple participants and a computer readable medium comprising instructions that cause the processor to perform automatically an action in response to and related to a sensed context during the video communication session. The action can be one or more of retrieve or provide content of interest to one or more of the participants, join a third party to the video communication session, recommend that a further action be performed by the processor, and schedule an activity involving one or more of the participants.

Abstract: Cost-effective structures and methods that allow an integrated digital-to-analog converter (DAC) to simultaneously achieve wide dynamic ranges and bandwidths through the use of built-in measurement and compensation mechanisms that are primarily digital. The measurements of the DAC's distortions are made with a relatively simple analog-to-digital converter (ADC) that is not designed to accommodate the combination of the bandwidth and the resolution offered by the DAC, but is nonetheless sufficient in determining the characteristics of the DAC's impairments during a calibration procedure. This information is then used in a feed-forward compensation system during the DAC's normal operation to estimate and cancel the distortions in its output signal that could result from the various impairments.
