Abstract
A method is provided for tagging a quality metric in adaptive bitrate (ABR) streaming, which allows a client to intelligently select a variant bitrate stream using the tagged quality metric. The method includes encoding multiple streams of video data at variant bitrates, each bitrate stream having a plurality of chunks, computing a quality metric for each chunk of each stream, and tagging the quality metric with each chunk of each stream.
