Abstract

With the recent development of wireless communications and multimedia systems, 3D image-based scenes with photo-realistic rendered images and rendering performance have recently received a great deal of interests.In this paper, we focus upon 3D scenes streaming over heterogeneous wireless communication networks, and we propose a real-time transport protocol for streaming 3D scenes based rendered by image morphing. Our approach is based upon 2D images (i.e., subfunction of plenoptic function) which are taken as a representation of 3D scenes while the view morphing is used to render new images. Based on these assumptions, we have designed the real-time transport protocol (RTP) payload format and packetization schemes for streaming 3D image-based scenes. Furtheremore, in order to enhance the robutness of our streaming mechanism, a special packetization scheme has been developed and a feedback mechanism is proposed to deal wih the drastic changes of the wireless network bandwidth using a periodic feedback schema within the Real-time Control Protocol (RTCP).We discuss our proposed protocol and present an extensive set of simulation experiments to evaluate the performance of our protocol using a variery of real world senarios.
