  • Patent number: 10104377
    Abstract: Described are techniques in video coding and/or decoding that allow for selectively breaking prediction and/or in loop filtering across segment boundaries between different segments of a video picture. A high layer syntax element, such as a parameter set or a slice header, may contain one or more indications signalling to an encoder and/or decoder whether an associated prediction or loop filtering tool may be applied across the segment boundary. In response to such one or more indications, the encoder and/or decoder may then control the prediction or loop filtering tool accordingly.

  • Patent number: 9001275
    Abstract: 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.

  • Patent number: 7436891
    Abstract: 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).

  • Patent number: 7298425
    Abstract: 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 for 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.

  • Patent number: 7289170
    Abstract: Disclosed are an apparatus and a method for compensating for an interlaced-scan type video signal for stably displaying the video signal in the LCD panel. An aft part of 264th data of a first field and a fore part of 23rd data of a second field are stored in memories. A present video signal is determined whether the present video signal is a first field signal or a second field signal through an equalizing pulse period. If the present video signal is the first field signal, a fore part of 23rd data is copied to the first data field, and if the present video signal is the second field signal, the aft part of the 263rd data is added to the second field data. In case of a PLA-type video signal, first data represent 23rd data, and final data represent 313rd data.

  • Patent number: 7256790
    Abstract: A video and graphics system includes a video decoding system for processing compressed video data. The compressed video data includes MPEG-2 video data containing SDTV video data or HDTV video data. The video decoding system includes a video decoder for processing the compressed video data to generate displayable video, and a memory controller for transferring the compressed video data to and from an external memory. The video decoder requests to the memory controller to transfer the compressed video data using one of predetermined addressing patterns. The predetermined addressing patterns allow for more efficient transferring of the compressed video data to and from the external memory when compared to sequentially transferring a fixed number of data bytes starting at a fixed address. The use of the predetermined addressing patterns results in reading the compressed video data from the external memory in a predetermined order in a less number of clock cycles.
