QLs were previously extended to slain and multiple-view scalable video for efficient transport of 3DTV over the Internet. However it is not possible to use the QL method in applications that require real-time encoding since the :priority determination process assumes the availability of the whole video sequence. In this work a trellis-based online rate adaptation is proposed far: real-time scalable stereo video coding with a delay of I group of pictures (GoP). The delay can be controlled by selection of the GoP size according to the application, such as 16 frames for live broadcast or 8 or 4 frames for videoconferencing. In addition the joint optimization of layer extraction for scalable multiview coded stereo video is also proposed. It is assumed that the encoder/extractor is aware of the available dynamic: network bandwidth in order to perform rate-distortion optimized medium-grain fidelity scalability layer selection for each GoP. Experimental results show that the performance of the proposed online :method is very close to that of QLs that would require the whole video sequence.Englishinfo:eu-repo/semantics/openAccess3DTV, dynamic rate allocation, quality layers, scalable video coding, scalable multiview video coding, trellis-based optimizationQUALITY LAYERS, BIT ALLOCATION, COMPRESSIONScalable Multiview Video CodingDynamic Rate AllocationMühendislik, Elektrik Ve ElektronikBilgisayar Bilimleri, Teori Ve MetotlarQuality Layers3DTVScalable Video CodingTrellis-Based OptimizationArticle
