ABSTRACT:
Apparatus for and method of sending a video bitstream, including a plurality of high priority segments and associated low priority segments, by transmitting only the low priority segments from a transmitter over a facility to a receiver is disclosed. The transmitter and receiver locations are arranged to use previously agreed-to high priority information (e.g., predefined high priority segments or format for generating same) and, consequently, only the low priority segments of the video bitstream need to be transmitted to the receiver. At the receiver, the high priority segments are obtained (from storage or generated using the agreed-to format) and interleaved in real time with the received low priority segments to recreate an interleaved video bitstream.
