Abstract
Approaches to preventing degraded video presentation use reference video quality measurement feedback from a video decoder node that is receiving live action video streams from a video encoder across a cellular network. A reference video stream is encoded along with the live action video streams, and the video decoder node compares the decoded reference video stream with a local copy to determine video quality. The video decoder node provides video encoding parameter feedback for adjusting the encoding and/or provides cellular network feedback for adjusting a transmission parameter for data traffic through the cellular network (from the video encoder node to the video decoder node). Solutions are disclosed for implementation at the video encoder, at the video decoder, and within the cellular network. For example, different compression codecs may be specified, and bit rates, frame, rates, key frame intervals, and/or bit depth may be automatically (immediately) adjusted without requiring human intervention.
