The Video Gross Error Detection methodology is designed to provide a platform independent, automated way to measure content delivery and quantify the video playback experience.
GED operates directly on the video file itself, instrumenting each frame with visible identifiers. These identifiers are composed of an array of color blocks that encodes an ordinal which represents the intended presentation order. To perform a GED measurement, the video is played through the system under test and the results captured. By examining the capture file, the GED can compare the observed results with the expected ordinal sequence to determine if any frames have been dropped, repeated or presented out of sequence.
