Patent attributes
A computer-implemented method of displaying frames of digital video is provided. The method includes processing contents in one or more predetermined regions of the frames to detect predetermined non-image data. In the event that the predetermined non-image data is undetected within the one or more predetermined regions of a particular frame being processed, subjecting the particular frame to a predetermined texture-mapping onto a predetermined geometry and displaying the texture-mapped frame; and otherwise subjecting the particular frame to cropping to remove the non-image data, flat-projecting the cropped frame and displaying the flat-projected cropped frame. A computer-implemented method of processing digital video is also 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: processing contents in one or more predetermined regions of the frames to detect predetermined non-image data therefrom. In the event that the predetermined non-image data is undetected within the one or more predetermined regions in a particular frame being processed, deeming the particular frame to be the event-triggering frame and executing one or more events associated with the event-triggering frame at the time of display of the event-triggering frame.
