  • Patent number: 8804839
    Abstract: In a method for image prediction of a multi-view video codec, a disparity vector value of a current macroblock is obtained and a corresponding macroblock is searched through the obtained disparity vector value. An intra prediction coding direction value of the searched macroblock is determined as an intra prediction coding direction value of the current macroblock. The current macroblock is coded/decoded through the determined intra prediction coding direction value. The coding efficiency can be increased by reducing a coding amount by omitting a process of obtaining an unnecessary disparity value by using a different-view intra prediction coding direction as a current-view intra prediction coding direction. The coding efficiency can be increased by reducing a coding amount by differentially coding a similar disparity vector. The reliability can be increased through an accurate disparity using multiples of 8 rather than 16, in motion skip for sharing the format of a macroblock.

  • Patent number: 8691142
    Abstract: Zr—Ti—Ni(Cu)-based filler alloy composition having low melting point for brazing titanium and titanium alloys is expressed as: ZraTibNic (Formula 1) where a, b and c denote atomic % of Zr, Ti and Ni, respectively; 47?a?52; 24?b?30; 22?c?26; and 0.3<c/(a+c)<0.35, or ZraTibNicCud (Formula 2) where a, b, c and d denote atomic % of Zr, Ti, Ni and Cu respectively; 48?a?60; 20?b?28; 19?c+d?30; 3?d?12; and 0.12<d/(c+d)?0.5. Including Zr(Ti) solid solution phase as major constituent phase, the alloy compositions have lower liquidus temperature than those of conventional alloys and they include a little amount of Cu or does not include it at all. When the alloy is used as filler alloy for brazing titanium and titanium alloys, brazing can be performed at remarkably low temperature. This can inhibit the microstructure of titanium base metal from changing and being damaged, keeping the titanium base metal preserving inherent properties after brazing.

  • Publication number: 20120299929
    Abstract: The present invention relates to a multimedia-data-processing method which enables a media graph to always be constructed in a “connection without negotiation” manner, on the basis of an already known media graph construction, and thus provides a media framework in which procedures for connecting components are minimized, thereby improving the performance of a system and satisfying the requests of an OS platform builder and a media application developer. The multimedia-data-processing method of the present invention is performed by a multimedia framework, and comprises: (a) a step of receiving component information required for the construction of the media graph and component connection information from a media application; and (b) a step of ensuring that the media graph is constructed by the content received in step (a), and that the media graph waits for a rendering command, thereby eliminating the necessity of permitting the media application to check the construction of the media graph.
