Patent ID: 7830958

Claim:
A run-time method for increasing a data rate of a video bitstream during bitstream playback, comprising: identifying a switching up period for switching between a first bitstream and a second bitstream, wherein the second bitstream provides a higher data rate than the first bitstream; establishing a third bitstream during the switching up period, the third bitstream to carry additional data associated with a switch up from the first bitstream to the second bitstream; and switching up from the first bitstream to the second bitstream during the switching up period; wherein the first bitstream includes 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; wherein the second bitstream includes second encoded data for the plurality of frames within the video sequence, the second encoded data being at least partially transmitted in a base layer portion of the second bitstream; and wherein the first encoded data transmitted in the base layer portion of the first bitstream are based on reconstructed frame data using at least the second encoded data transmitted in the base layer portion of the second bitstream.
