Patent number: 9001275Abstract: HDMI is a digital audio and video communications protocol commonly used in consumer electronics. HDMI is particularly synonymous with high fidelity audio and video. Even though HDMI is a digital communications protocol, the audio quality can be impaired by analog signal impairments and distortions even if there are no digital decoding errors. In particular, the very process by which the audio is converted from Digital (HDMI) to human audible “Analog Audio” can be prone to errors. This occurs when the Digital to Analog Converter (DAC) clock, which is derived from the HDMI TMDS clock or HDMI source, is “distorted” due to its jitter, resulting in erroneous sampling or outputting of vital audio samples, thereby reducing the audio quality of the experience. The present invention reduces the jitter on the TMDS clock, and hence the audio DAC clock, resulting in lower audio distortion.Type: GrantFiled: November 19, 2013Date of Patent: April 7, 2015Inventors: Andrew Joo Kim, David Anthony Stelliga

Patent number: 7768520Abstract: In a video application, a method and system provide different sizes of data-fetch where the data transfer rate between a decoder and an external memory (e.g., DDR memory) is extremely high, as for example in HDTV systems. The invention in one form divides a reference frame into different tiles where each tile is hierarchically divided into smaller tiles to a level where the minimum tile size is the same as the fixed burst size of the DDR memory. The method also provides for arranging the biggest tiles into different banks and pages so that even if the block to be fetched falls across tile boundaries, the latency penalty in the tile transition will be minimized. The invention provides advantages also for progressive and interlaced data fetch.Type: GrantFiled: May 3, 2006Date of Patent: August 3, 2010Assignee: Ittiam Systems (P) Ltd.Inventor: Sutirtha Deb

Patent number: 7595844Abstract: One embodiment of the present invention provides a method that facilitates compression of video data in a computer system by performing the time-consuming task of computing the difference between successive frames of video data independently from the central processing unit. This frees the often-overburdened central processing unit from performing this time-consuming compression operation and can thereby improve the handling of video data. Thus, one embodiment of the present invention can be characterized as a method thr compressing video data in a computer system. This method includes receiving a stream of data from a current video frame in the computer system. It also includes computing a difference frame from the current video frame and a previous video frame “on-the-fly” as the current video frame streams into the computer system. The method additionally includes storing the difference frame in a memory in the computer system.Type: GrantFiled: September 11, 2006Date of Patent: September 29, 2009Assignee: Micron Technology, Inc.Inventor: Dean A.

Patent number: 7436891Abstract: An image data decompression apparatus for decoding blocks of motion compensated non-intra coded data uses a memory (14) storing reference picture data. A decoding processor (12) decodes a current block of a generated picture using lines of previously decoded image data from the memory (14) that are selected in dependence upon a motion vector (V1) for the current block. In order to improve access efficiency to the memory (14) the decoding processor (12) concatenates fetches into bursts for different sections of lines of previously decoded data that lie within a predetermined range within the memory addresses of the memory (14).Type: GrantFiled: June 27, 2003Date of Patent: October 14, 2008Assignee: Broadcom CorporationInventor: Mark Taunton
