Abstract: A method includes: receiving a request to identify a video within a video stream; identifying a plurality of frames associated with the video stream; adjusting respective frames of the plurality of frames based in identified changes in angular motion between the respective frames of the plurality of frames; identifying a plurality of candidate edges using the video stream captured by the first device; responsive to identifying the plurality of candidate edges, selecting edges enclosing a display area in the video stream corresponding to a second device; creating a fingerprint for the video based on content included in the display area; identifying video information based on the created fingerprint; and transmitting instructions to display the video information.
