JPEG2000 based real-time scalable video communication system over the Internet

This paper presents a JPEG2000 based real-time scalable video communication system developed in Sony, named as "BEAM" video system. Two practical objectives are emphasized in this system: scalable video communication and real-time communication. We extend IETF RTP and RTSP streaming protocol to take care of scalable delivery of video data from a single layered coding data to heterogeneous devices and different resolution display such as HDTV, standard TV, PDA and mobile phone. Utilizing an advantage of low coding delay JPEG2000 codec, real-time ARQ (RT-ARQ) is proposed to resolve the QoS issues for real-time applications. In addition to this protocol, various network adaptive control techniques, including rate control and error control, are presented to achieve high quality video transmission.
