With the rapid development of multi-view video coding (MVC) and light field rendering (LFR), Free-View Television (FTV) has emerged as new entrainment equipment, which can bring more immersive realistic feelings for TV viewers. In FTV broadcasting system, TV-viewer freely watch a arbitrary view scene generated from number original views. such scenario, ownership should be verified not only on views, but also any virtual view. However, capacities existing watermarking schemes copyright protection methods LFR-based are one bit, i.e., presence or absence watermark, seriously impacts its usage in practical scenarios. this paper, we propose robust multi-bit scheme free-view video. The direct-sequence code division multiple access (DS-CDMA) watermark is constructed according to message embedded into DCT domain each frame. extracted bit-by-bit frame at an view-point with correlation detector. Furthermore, mathematically prove that detected Experimental results show successfully Moreover, proposed method against common signal processing attacks, Gaussian filtering, salt & peppers noising, JPEG compression, center cropping.
