摘要： The disclosure relates to a communication client application for running on a user terminal to conduct calls over a network. The client is configured to access a model which models quality of user experience for calls based on a set of technical parameters of each call. The model itself is based on user feedback indicating subjective quality of multiple past calls as experienced by multiple users, modeled with respect to the technical parameters collected from each of the past calls. The model generates a predicted call quality score predicting the quality of user experience for the call given its technical parameters. Based on this process, one or more of the technical parameters of the call can be adapted to try to increase the quality experienced by the user.

摘要： A method for processing encoded data bits transmitted from a transmitter to a receiver over a lossy communication channel, the method comprising: receiving the encoded data bits over the communication channel, the encoded data bits including redundant data units; decoding the encoded data bits at an error correction decoder, wherein the recovery of lost data is implemented at the error correction decoder using at least one of the redundant data units; determining if at least one data bit is unable to be recovered due to the decoder finding a plurality of candidate bit values for the at least one data bit; receiving information relating to the transmitter; analyzing the plurality of candidate bit values to exclude at least one of the candidate bit values for the at least one data bit using information relating to the transmitter; and resolving the at least one data bit based on the analysis.

摘要： 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.

摘要： 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.
