This paper presents an object-oriented unequal loss protection scheme for robust wireless scalable 3D-SPIHT encoded video transmission using product codes. In our proposed OOULP system, the embedded video bitstream of all concerned video objects are packetized independently for transmission over wireless network. The scheme employs regular LDPC codes and Reed-Solomon codes to deal effectively with burst errors over wireless network. For optimal unequal loss protection, a coarse-to-fine strategy has been used to assign unequal rate allocation to each object within the video:(a) coarse allocation: the inter-object rate allocation assign the rate budget among different objects according to their priority level; (b) fine allocation: intra-object rate allocation provides byte-wise protection to the embedded bitstream of each object to minimize its individual mean distortion. Our proposed framework allows the users to independently access and manipulates the objects with their interests. The simulation experiment shows that the proposed framework is robust in hostile network conditions and therefore can provide reasonable visual qualities for different video objects according to their importance.
