Abstract
MPEG-21 Digital Item Adaptation (DIA) provides digital items being adapted according to user preferences and terminal capabilities. This paper considers the implementation of stereoscopic adaptation in the DIA Testbed being composed of a DIA server, a client, and a network interace module. User preferences considered for the stereoscopic adaptation are the types of stereoscopic parallax, the range of 3-D depth, and the interval of a previous frame. Such descriptors are sent to the DIA server in the form of XML. Then, the server adapts the descriptors as well as resources and transmits them to the client. At the server side, MPEG-1 video is converted into stereoscopic MPEG-4 video. Upon receiving the streamed video in RTP, the client displays the stereoscopic video. RTP/RTSP and TCP/IP protocols are used to deliver various types of data between the client and server.
