Abstract: Correction data units for data packets of a data stream are generated. A correction data unit is based on a set of the data packets of the stream. The stream is transmitted over a lossy communication channel. A performance measure to be optimized is selected, which relates to the recovery of lost data packets of the stream. A coding requirement is determined. For the generation of the correction data units, it is determined, within the constraints of the coding requirement and based on previously generated correction data units, which of the data packets in the stream to include in the set on which the generation of the correction data unit is to be based to thereby optimize the selected performance measure. A generated correction data unit is generated based on a respective set of the data packets of the stream. The generated correction data units are included in the stream.

Abstract: Correction data units for data packets of a data stream are generated. A correction data unit is based on a set of the data packets of the stream. The stream is transmitted over a communication channel. A performance measure to be optimized is selected, which relates to the recovery of lost data packets of the stream. To optimize the performance measure, a plurality of correction data vectors are determined, and a plurality of a plurality of non-recovery probabilities, corresponding to the correction data vectors, are initialized. One or more of the correction data vectors are selected that contribute towards a non-recovery probability of an original data packet. The non-recovery probability associated with the original data packet is then minimized based on the selected one or more correction data vectors. The selected one or more correction data vectors are then used to determine which of the original data packets or data correction units to transmit.

Abstract: Methods and systems for controlling a computing-based device based on gestures made within a predetermined range of a camera wherein the predetermined range is a subset of the field of view of the camera. Any gestures made outside of the predetermined range are ignored and do not cause the computing-based device to perform any action. In some examples, the gestures are used to control a drawing canvas that is implemented in a video conference session. In these examples, a single camera may be used to generate an image of a video conference user which is used to detect gestures in the predetermined range and provide other parties to the video conference session a visual image of the user.
