SYSTEM AND METHOD FOR 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 to optimize the encoding process of the source video. The system and method extract content characteristics from the source video by sampling the source video, and then classify the video into one or more content classes based on the extracted characteristics. The content class of the video 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 and determining optimal transitional rates for the plurality of videos. The sampled videos may be used to generate a decision boundary to classify whether a particular video is a good candidate for spatial down-sampling.
