VIDEO DATA STREAM EVALUATION SYSTEMS AND METHODS

摘要

A machine-controlled method of evaluating a video data stream having multiple broadcast channels can include selecting at least two video frames for a particular channel, extracting the selected video frames from the video data stream, decoding the extracted video frames, comparing at least one of the decoded video frames to the other decoded video frame(s) or a previously stored video frame, and preparing an evaluation of the video data stream based on the comparing.
