Abstract
A method, system, and computer program product for adaptive decoding is provided herein. The method includes the steps of receiving a video bitstream, selecting an initial extraction level, and switching to a lower quality extraction level if a decoding rate is less than a rate at which data extracted from the video bitstream is sent to the decoder. The method further includes the step of switching to a higher quality extraction level if the decoding rate is greater than a rate at which data extracted from the video bitstream is to the decoder.
Claims16
An adaptive decoding system, comprising:
- a bitstream extractor configured to extract data including one or more of temporal sub-layers, reference frames, non-reference frames, or Random Access Point (RAP) pictures from a video bitstream;
- a decoder coupled to the bitstream extractor and configured to decode the data extracted by the bitstream extractor;
- a decoding speed monitor configured to determine a decoding rate at which the decoder decodes the data extracted by the bitstream extractor;
- and
- a quality of experience (QoE) selector coupled to the decoding speed monitor and the bitstream extractor and configured to adjust an extraction quality level of the bitstream extractor based on a comparison of the decoding rate and a rate at which the bitstream extractor sends the data to the decoder.
