PROVIDING CONTENT AWARE VIDEO ADAPTATION

摘要

A method and system for providing content aware media adaptation are described. Aspects of the invention adaptively down-sample a source video 102 to optimize the encoding process of the source video 102. The system and method extract content characteristics from the source video 102 by sampling the source video 102, and classify the video 102 into one or more content classes based on the extracted characteristics. The content class of the video 102 is used to determine one or more down-sampling settings for the source video. In some aspects, the down-sampling settings are derived by sampling a plurality of videos 102 and determining optimal transitional rates 500 for the plurality of videos. The sampled videos may be used to generate a decision boundary 606 to classify whether a particular video is a good candidate for spatial down-sampling.
