Abstract:
1. A system for generating a list of content-based scene transitions within a stream of video data, the system comprising: a video decoder engine configured to receive the video data and to generate a plurality of video frames based on the video data; a frame buffer for storing the plurality of video frames; a frame correlation engine configured to generate at least one correlation coefficient based on a comparison between at least two video frames in the plurality of video frames, wherein the at least one correlation coefficient is used to determine whether a scene boundary exists between any of the at least two video frames; and a data transport engine configured to transfer the at least one correlation coefficient to a playback application executing on a central processing unit (CPU) to allow the playback application to determine whether a scene boundary exists between any of the at least two video frames based on the at least one correlation coefficient and to generate an entry in a list of scene transitions when a determination is made that a scene boundary exists.
