Multiview video coding (MVC) is essential for applications of the
auto-stereoscopic three-dimensional displays. However, the computational complexity
of MVC encoders is tremendously huge. Fast algorithms are very desirable for the
practical applications of MVC. Based on joint early termination , the selection of
inter-view prediction and the optimization of the process of Inter8×8 modes by
comparison, a fast macroblock(MB) mode selection algorithm is presented.
Comparing with the full mode decision in MVC, the experimental results show that
the proposed algorithm can reduce up to 78.13% on average and maximum 90.21%
encoding time with a little increase in bit rates and loss in PSNR.
We propose that nanomaterials can be used for fibers. A novel nano-InP doped fiber has been fabricated by the method of
modified chemical vapor deposition (MCVD).It has been measured that the doping concentration is 0.1%. The
relationship between refractive index and the wavelength is obtained by fitting experimental data to Sellmeier equation.
Dispersion of the fiber has been calculated in the wavelength range 1.2-1.6μm. As the wavelength varies from 1.2μm to
1.60μm, dispersion parameter D increases but is always negative. It has found that the dispersion of nano-InP doped
fibers is strongly changed compared to standard single-mode fibers, due to the nano-InP dopant which lead to a higher
refractive index difference.
As the key of these all optical techniques which would be widely used in the future optical fiber communication, the
stimulated Brillouin scattering (SBS) slow light draws a great of attention and shows several advantages over other slow
light methods. With recent growth of nano-technology, researchers are hoping to improve the nonlinearity of the optical
fiber by using the nano-technology. According to this current situation, a numerical model of the SBS slow light and
three typical experiments are discussed. A novel optical fiber doped with nano material as InP is manufactured and
introduced into the SBS slow light, serving as the nonlinear medium of SBS process. And the numerical simulations are
performed to validate our method. The results show a considerable time delay of the optical light can be achieved
through this novel optical fiber.
