Patent ID: 8582952

Claim:
A method of identifying chapter markers in a video presentation, comprising the acts of: receiving first video data representative of a presentation comprising a plurality of static images; receiving second video data; combining the first video data and the second video data to form a composite video; extracting a first portion of the first video data representative of a first video frame and a second portion of the first video data representative of a second video frame; determining a difference blend measurement for each of a plurality of pairs of spatially corresponding pixels between the first video frame and the second video frame; evaluating the difference blend measurements for the plurality of pairs of spatially corresponding pixels at least in part through use of a Root-Mean-Square (RMS) analysis; identifying, based at least in part on the analysis, a transition point between the first video frame and the second video frame, wherein the transition point is representative of a transition between consecutive static images in the presentation; and associating a chapter marker with the composite video based, at least in part, on the identified transition point, wherein a positioning of a display of the first video data relative to a display of the second video data in the composite video is adjusted for a specified time period after the chapter marker.
