Abstract:
In accordance with an example embodiment of the present invention, there is provided an apparatus configured to instruct a redundancy encoder to increase a level of redundancy of a media stream, an error rate determination to determine an error rate of a communication path conveying the media stream with increased redundancy, a comparator configured to compare a bandwidth used to convey the encoded media stream at the increased redundancy level with a bandwidth for conveying the encoded media stream at a second quality level greater than the first quality level, the apparatus being further configured to provide a switching signal to a media encoder to start encoding the media stream at the second quality level responsive to the used bandwidth being sufficient for conveying the media stream encoded at the second quality level and the determined error rate being less than a predetermined threshold value.
