In an optical waveguide fabrication process, medium weight, relatively stable ions, such as oxygen ions, are implanted, preferably in a multiple-step, multiple-energy level process, into GaAs, InP or other like III-V materials and heterostructures and then annealed by radiant heat, in order to produ.....

Motion compensated prediction (MCP) is the key to the success of the modern video coding standards. With MCP, the video signal to be coded is predicted from the temporally neighboring signals, and only the prediction error and the motion vector (MV) are transmitted. However, due to the finite sampl.....
