Abstract:
1. A computer-implemented method executable on a processor for switching between a first bitstream and a second bitstream, wherein the second bitstream provides a higher data rate than the first bitstream, the method comprising: identifying a switching up period associated with the first and second bitstreams, the first bitstream comprising first encoded data for a plurality of frames within a video sequence, the first encoded data being at least partially transmitted in a base layer portion of the first bitstream; establishing a third bitstream during the switching up period, the third bitstream being configured to carry additional data associated with a switch up from the first bitstream to the second bitstream, wherein the additional data is based at least on a difference between a first reconstructed image from the first bitstream and a second reconstructed image from the second bitstream; and switching up from the first bitstream to the second bitstream during the switching up period.
