System and method for processing digital video

Abstract

A computer-implemented method of processing digital video is provided. The method includes determining at least one frame region the contents of which would be rendered substantially invisible, were frames of the digital video to be subjected to a predetermined texture-mapping onto a predetermined geometry; and inserting non-image data into at least one selected frame by modifying contents within at least one determined frame region of the selected frame. Another computer-implemented method of processing digital video is provided. The method includes, for each of a plurality of frames of the digital video: processing contents in one or more predetermined regions of the frame to extract non-image data therefrom; subjecting the frame to a predetermined texture-mapping onto a predetermined geometry, wherein after the texture-mapping the contents of the one or more predetermined regions are rendered substantially invisible; and causing the texture-mapped frame to be displayed. Another computer-implemented method of processing digital video is provided. The method includes for each of a plurality of frames of the digital video: extracting a frame identifier uniquely identifying a respective frame by processing contents in one or more predetermined regions of the frame; and for each of a different plurality of frames of the digital video: estimating the frame identifier based on playback time of the digital video. Another computer-implemented method of processing digital video is provided. The method includes causing frames of the digital video to be displayed; for a period beginning prior to an estimated time of display of an event-triggering frame and ending after the estimated time, causing a frame that is to be displayed prior to the beginning of the period to remain displayed; and after the period, executing at least one event associated with the event-triggering frame and resuming display of subsequent frames of the digital video. Systems and computer-readable media are also provided.
