Patent number: 9729817Abstract: A device for multiple-quality level video processing includes a primary tap configured to receive prime-quality video content from a source and to provide the prime-quality video content to a primary path and to a secondary tap. The primary tap may be operable in a prime-quality mode. The secondary tap may be disposed after the primary tap and may be coupled to a number of secondary paths. One or more dithering modules may be disposed after the primary tap. The dithering module(s) may be configured to convert the prime-quality video content provided by the primary tap to lower-bit precision and/or lower pixel-rate video content for use in one or more of the secondary paths.Type: GrantFiled: December 4, 2013Date of Patent: August 8, 2017Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE.

Patent number: 8942295Abstract: Herein described is a method and system of vertically filtering a graphics image such that an enhanced image is provided to a display. Filtering of the graphics image may be accomplished by using one or more window descriptors. The method may be implemented by computing a weighted average of one or more pixel intensities. The system may comprise a memory, a processor, and a graphics engine. The graphics engine may comprise a graphics blender. The graphics blender may comprise one or more multipliers and one or more adders. The processor may execute software resident in the memory, such that the one or more window descriptors may be used to compute the weighted average.Type: GrantFiled: March 29, 2011Date of Patent: January 27, 2015Assignee: Broadcom CorporationInventors: Chengfuh Jeffrey Tang, Steven (Yao-Hua) Tseng

Publication number: 20050039102Abstract: Provided is a system and method for performing CRC analysis in a video test bench. An exemplary system includes a memory configured for storing a required number representative of the data fields to be analyzed. A module is coupled at least indirectly to the memory and configured for (i) receiving an input data stream, (ii) performing cyclic redundancy check (CRC) analysis of the received data stream, and (iii) producing an output representative of an actual number of received data fields analyzed. The input data stream includes synchronization markers defining boundaries of each of the received data fields. Next, a comparator is configured for (i) comparing the required number and the actual number and (ii) producing a disabling signal when the actual number matches the required number.Type: ApplicationFiled: August 25, 2003Publication date: February 17, 2005Inventors: Darren Neuman, Chengfuh Tang, Yao-Hua Tseng, Guang Shih, Wen Huang

Publication number: 20050035975Abstract: Provided is a method and system for performing color look-up table (CLUT) and gamma correction for video pixel data. A system includes a memory configured for storing CLUT parameters and gamma correction parameters therein. Also included is an input matrix coupled to the memory and configured to receive first and second type pixel data. The memory receives the first type pixel as an address to the stored CLUT parameters and receives the second type pixel data as an address to the stored gamma correction parameters.Type: ApplicationFiled: August 14, 2003Publication date: February 17, 2005Inventors: Chengfuh Tang, Yao-Hua Tseng, Hsien-Chih Tseng
