Integrated error resilient solutions for Motion JP2 video streaming

Abstract

Two of the main challenges and critical issues facing real-time wireless multimedia transmission are packet loss and transmission errors. This thesis has selected Motion JPEG 2000, the newest standard for still image coding, for real time video streaming. JPEG2000 offers a number of qualities of service and revenue strategies that make it a leading contender for image streaming applications. We offer extra protection for the wireless transmission of JPEG2000 code streams due to error prone and changeable wireless channel conditions, and since the baseline JPEG 2000 error resilience tools are not sufficient in the context of wireless transmissions. Also, to accommodate the video streaming, avoid packet loss, and achieve efficiency, a payload format for JPEG 2000 video streams over the Real-time Transport Protocol has been defined. The main contribution of this thesis is adopting the packetization strategies and proposing an unequal error protection approach to improve the error resilience tools in baseline JPEG 2000 utilized in wireless streaming over the RTP. Our unequal error protection solution is directly supplied by a mechanism embedded in the JPEG 2000 syntax. At the end, the proposed approach is evaluated subjectively and objectively against existing wireless imaging techniques to demonstrate the achieved quality.
