  • Publication number: 20180084273
    Abstract: Provided is a video encoding/decoding technique for improving the compression efficiency by reducing the motion vector code amount. In a video decoding process, the prediction vector calculation method is switched from one to another in accordance with a difference between predetermined motion vectors among a plurality of motion vectors of a peripheral block of a block to be decoded and already decoded. The calculated prediction vector is added to a difference vector decoded from an encoded stream so as to calculate a motion vector. By using the calculated motion vector, the inter-image prediction process is executed.

  • Publication number: 20170073801
    Abstract: An aluminum alloy has high thermal conductivity without requiring an addition of metal elements such as iron and a method for producing the aluminum alloy. The aluminum alloy is obtained from a semi-solid material with a chemical composition containing 2 to 6 wt % of silicon (Si) and 0.7 wt % or less of magnesium (Mg), with the balance being aluminum (Al) and unavoidable impurities. It has a granular crystalline structure. The aluminum alloy is produced by a heating step of semi-solid material. A forming step is performed with semi-solid material obtained in the heating step S1. After the forming step, a heat treatment step is performed at 190° C. to 290° C. for 1 to 5 hours.
