Abstract:
1. A computer-implemented method of encoding partial-frame video segments to allow different partial-frame video segments to be merged into a full-video frame, said method comprising: defining by a processor a full-screen template by dividing said full-video frame area into non-overlapping, rectangular regions, wherein said rectangular regions have a length and width that are each a multiple of 16 pixels; obtaining discrete partial-frame video segments from a digital library to be inserted into at least one of said rectangular regions; determining by the processor a target VBV buffer size for said discrete partial-frame video segments for a selected rectangular region, said target VBV buffer size substantially proportional to a full frame VBV buffer size based on a relative size of said rectangular region to a full frame size; and independently encoding said discrete partial-frame video segments for insertion by the processor into said selected rectangular region using said determined target VBV buffer size, creating encoded discrete partial-frame video segments capable of being spatially seamlessly stitched into the non-overlapping rectangular regions of a full frame prior to decoding.
