Patent number: 8035751Abstract: A system and method for detecting the presence and location of pull-down fields in a video field stream. Various aspects of the present invention may comprise method steps and circuit structure for generating an array of variance indications, each of which represents a degree of variance between two video fields in the video field stream. Various aspects may comprise comparing the array of variance indications to a pattern to detect a pull-down field in the video field stream. Various aspects may comprise comparing corresponding portions of video fields and generating a histogram of differences between the corresponding portions. Various aspects may comprise generating an indication of variance of the histogram and analyzing the indication of variance. Various aspects may comprise analyzing an array of such indications of variance and may comprise comparing the array of such indications to a pattern or plurality of patterns.Type: GrantFiled: September 25, 2009Date of Patent: October 11, 2011Assignee: Broadcom CorporationInventors: Darren Neuman, Joseph Del Rio, Vadim Kochubievski, Craig Zinkievich, Shannon Posniewski, Alexander G.

Patent number: 6356273Abstract: A method and system for processing textures for a graphical image on a display is disclosed. The graphical image includes a plurality of polygons. Each of the plurality of polygons includes at least one fragment. The fragment includes at least one texture and a w-value for the fragment. Each polygon has a plurality of vertices, a display area, and a texture space area. Each of the vertices has a vertex w-value. The at least one texture is associated with at least one MIP map. The MIP map includes a plurality of MIP map levels. The method and system include determining a selection value for each fragment of a polygon of the plurality of polygons. The selection value includes ½ multiplied by the base two logarithm of the texture area divided by the display area and divided by the product of the vertex w-values for each of the plurality of vertices. The selection value also includes 3/2 multiplied by the base two logarithm of the w-value for each of the at least one fragment.Type: GrantFiled: June 7, 2000Date of Patent: March 12, 2002Assignee: Broadcom CorporationInventors: Shannon Posniewski, Vadim Kochubievski, Glenn Nissen, Aleksandr Movshovich, Michael C.
