Abstract: A method is provided for a computer to measure performance. The method includes capturing frames of at least a portion of a video on the computer and detecting timestamps on the captured frames, and determining a frame rate of the video playback based on the timestamps. Each timestamp includes data elements of first and second colors that are spaced apart from each other and set against a background of a third color so adjacent data elements are separated by areas of the third color.

Abstract: A method is provided to measure a relative frame rate of a remote desktop on a first computer and accessed by a second computer. The method includes playing a video timestamp on the remote desktop at the first computer where the video timestamp includes unique timestamps, screen capturing the remote desktop at the first computer and the second computer, determining a first frame rate at the second computer based on the screen capturing the remote desktop at the second computer, determining a second frame rate at the first computer based on the screen capturing the remote desktop at the first computer, and determining the relative frame rate as a ratio between the first and the second frame rates.

Abstract: A method is provided to measure an overall image quality score for a remote desktop on a first computer and accessed from a second computer. The method includes playing a video timestamp on the remote desktop at the first computer where the video timestamp includes unique timestamps, screen capturing first computer frames of the remote desktop at the first computer and second computer frames of the remote desktop at the second computer at the same time, determining a frame image quality score for each second computer frame by comparing the client screen to a corresponding baseline first computer frame, and determining the overall image quality score for the remote desktop from frame image quality scores of the second computer frames.
