Abstract
A system and method of evaluating a decoder under test can include the steps of storing a first segment of a video sequence for creating a first test frame portion including a first image, storing a second segment of video sequence for creating a second test frame portion including a second image, combining the first and second test frame portions into a visualization segment, streaming the visualization segment to the decoder, displaying the resultant output stream from the decoder under test, and determining if a defect exists in the displayed decoded output stream. Determining if a defect exists can include: if the display of the displayed visualization segment shows a steady picture, then determining there is a defect in the decoded picture, and if the display of the visualization segment shows flickering or flashing detail, then determining that there is a defect in the decoded picture.
