Such services allow users to share the virtual reality (VR)world without any geographical restrictions. In order to create a 3D system with two images (left and right) that should be transmitted over a bandlimited mobile channelsimultaneously, a cost-effective MPEG-based wavelet multiresolution coding with an joint motion- and disparity- compensation is developed to reduce a large amount of information contained in the images in order to the meet the low transmission rate limitationof mobile channels. However, the rapidly variable bit rate (VBR) characteristics of the MPEG- based 3D videos seems a weakness to the transmission of such videos via a constantbit-rate (CBR) mobile channel.The ATM technique is especially wellsuited for
