Synchronizing a map to multiple video formats

摘要

A method comprising comparing a frame rate of a source video program to a frame rate of a target video program to generate a conversion factor between the two sources; retrieving a target frame and retrieving, responsive to a location of the target video frame within the target video program, and responsive to the conversion factor, a source video frame from within the source video program; determining, by means of an image comparison, equivalence between the target frame and the source frame; and synchronizing, responsive to the determining, the target frame and the source frame, the synchronizing enabling a set of non-sequential segments of the target video program to be equivalent to a set of non-sequential segments of the source video program.

1. A method comprising the steps of:
comparing a video frame rate of a source video program to a video frame rate of a target video program to generate a conversion factor between the source video program and the target video program; retrieving a target video frame from within the target video program; storing in a memory, as a bitmap, the target video frame; retrieving, responsive to a location of the target video frame within the target video program, and responsive to the conversion factor, each of a plurality of source video frames from within the source video program; storing in a memory, as a bitmap, each of the plurality of source video frames; determining equivalence between the target video frame and each of the plurality of source video frames; the determining being responsive to a comparison of bits of the bitmap of the target video frame and bits of the bitmap of a source video frame; and synchronizing, responsive to the determining, the target video frame and one of plurality of source video frames, the synchronizing enabling a set of non-sequential video segments of the target video program to be equivalent to a set of non-sequential video segments of the source video program.
