The hybrid digital-analog (HDA) video transmission scheme can be used to avoid thecliff effectandsaturation effect. However, directly using HDA in 3D video transmission requires too much bandwidth. This paper addresses synthesis-distortion-aware HDA transmission for 3D videos to improve transmission performance. First, a 3D HDA framework that transmits both texture and depth videos in HDA mode is designed. Second, a recursive synthesis distortion estimation model, called RSDE-3D-HDA, is derived, where the transmission errors of both the texture and depth sequences are considered. Third, we optimize the power allocation between digital and analog signals based on the RSDE-3D-HDA. Finally, simulation results show that our model is accurate and the proposed 3D-HDA achieves better performance in terms of synthesis quality than state-of-the-art methods.
