Abstract
A test video sequence for testing quality loss in processed video. When video clips are transmitted, compressed/decompressed, or otherwise processed, measuring the loss of quality that occurs during processing can be improved by inserting specific types of overhead video data into the test video sequence before processing. When the processed test video sequence is compared to the pre-processed test video sequence, the overhead video data enables improvements in the comparison operation. In one embodiment, padded areas such as uniform-color frames are inserted at specified points to absorb some of the quality loss and/or to enable identification of starting and/or ending points of the video clips. In another embodiment, a special color bar is inserted before processing and used after processing to detect changes that should be corrected before comparing the video clips.
