Patent number: 9570110Abstract: 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.Type: GrantFiled: December 24, 2010Date of Patent: February 14, 2017Assignee: Korea Electronics Technology InstituteInventors: Byeong Ho Choi, Yong Hwan Kim, Hwa Seon Shin, Choong Sang Cho, Min Seok Park

Method for image prediction of multi-view video codec and computer-readable recording medium thereof
Patent number: 8804839Abstract: 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.Type: GrantFiled: June 25, 2008Date of Patent: August 12, 2014Assignee: Korea Electronics Technology InstituteInventors: Ji Ho Park, Byeong Ho Choi, Je Woo Kim, Yong Hwan Kim, Hwa Seon Shin, Yo Sung Ho
