Abstract
Methods and systems for pre-conditioning a video stream are provided herein. For example, an apparatus comprising a memory and one or more processors configured to execute instructions stored in the memory are provided. The instructions: identify packets of a first bitstream in a transport stream, such first bitstream corresponding to a base layer; identify packets of a second bitstream in the transport stream, such second bitstream corresponding to an enhancement layer; identify an initial packet corresponding to an ith picture in the first bitstream; identify an initial packet corresponding to the ith picture in the second bitstream; and reorder packets in the transport stream such that the initial packet corresponding to the ith picture in the second bitstream occurs after the initial packet corresponding to the ith picture in the first bitstream.
