Abstract: Methods and systems for achieving a high frame rate video with compatibility for existing receivers without depending bitstream encoding are provided herein. For example, an apparatus comprises: a memory; and one or more processors configured to execute instructions stored in the memory. The instructions comprise: receiving a first bitstream having a first packet identifier (“PID”) and a second bitstream having a second PID; decoding the first bitstream and the second bitstream; and interleaving the decoded first bitstream and the decoded second bitstream to form a high frame rate video signal, wherein the high frame rate video signal has a frame rate equal to the sum of the frame rate of the decoded first bitstream and the decoded second bitstream.

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.
