Patent number: 10542280Abstract: A video encoder is configured to determine whether to enable or disable an integer motion vector precision restriction and whether to enable or disable an illumination compensation (IC) tool by: for a large search range in a reference picture, performing first motion estimation tests, wherein performing the first motion estimation tests comprises performing motion estimation tests only with the IC tool disabled and the integer motion vector precision restriction disabled and with the IC tool enabled and the integer motion vector precision restriction disabled; based on the first motion estimation tests, determining a small search range, wherein the small search range is smaller than the large search range; for the small search range, performing second motion estimation tests; and based on the second motion estimation tests, determining whether to enable or disable the integer motion vector precision restriction and whether to enable or disable the IC tool.Type: GrantFiled: January 8, 2018Date of Patent: January 21, 2020Assignee: QUALCOMM IncorpatedInventors: Yu-Chen Sun, Wei-Jung Chien, Li Zhang, Yi-Wen Chen, Nan Hu, Marta Karczewicz

Patent number: 10534571Abstract: A presentation system is described herein. The system can include a room for playing a scene and can be made up of a collection of displays. The system can also include media players to manage the playing of content on a corresponding display of the collection of displays. The system can also include a server to distribute objects to the media players. The scene can include the objects, which may be selectively played on the displays when the scene is played on the room. The media players can receive the objects and can determine whether the objects are intended to be played on the corresponding displays as part of the scene to be played. If so, the objects can be rendered on the corresponding displays on which the objects are intended to be played, which can bypass the rendering of the scene as a whole by the system.Type: GrantFiled: February 16, 2017Date of Patent: January 14, 2020Assignee: Xevo Inc.Inventors: Ryan Anderson, Satoshi Nakajima

Patent number: 10536730Abstract: A method for processing video frames, a video processing chip, and a Motion Estimation/Motion Compensation (MEMC) chip are provided. The method performed by the video processing chip includes obtaining multiple video frames and adjusting each video frame from a first resolution to a second resolution. The method also includes inserting at least one invalid frame into the multiple video frames according to a second frame rate, so that a frame rate of a transport frame stream is the second frame rate; and sending the transport frame stream to an MEMC chip. The video processing chip and the MEMC chip may perform transmission of a frame stream according to an interface frequency corresponding to a resolution and a frame rate that are agreed upon.Type: GrantFiled: July 3, 2017Date of Patent: January 14, 2020Assignee: Huawei Technologies Co., Ltd.Inventor: Lijuan Tan

Patent number: 10531103Abstract: A video coder includes a processing resource and a non-transitory storage device containing instructions executable by the processing resource to compute a weighted ? frame based on a saliency map and a ? frame. The saliency map is to indicate the relative importance of each pixel in a current frame based on its perceptual significance. The ? frame is to include differences between corresponding pixels in a current frame and a motion predicted frame.Type: GrantFiled: October 16, 2014Date of Patent: January 7, 2020Assignees: Purdue Research Foundation, Hewlett-Packard Development Company, LP.Inventors: Mark Shaw, Jan P.

Patent number: 10530387Abstract: A system orders a set of objects to be optimally compressed using techniques such as delta encoding which compress data by saving differences between sequential objects. In one embodiment, the system determines transition costs associated with transitioning from each object in the set to each other object in the set. The system determines an ordering of the objects that minimizes a total of all the transition costs and compresses the set in the determined order. In another embodiment, the system determines an estimated optimal ordering for data compression. The system extracts feature values from the objects and applies a projection function to the feature values to generate scalar representations of the objects, for example, by projecting the feature values onto a space filling curve. An ordering of the scalar values for the objects determines an ordering for compressing the objects.Type: GrantFiled: October 22, 2018Date of Patent: January 7, 2020Assignee: Uber Technologies, Inc.Inventor: Bob Hansen

Patent number: 10522241Abstract: Methods and systems for accelerated input data conversion include partially parsing an input data set to convert the data set from a first format to a second format in an intermediate output having at least one unparsed portion to quickly perform a majority of the conversion. The partial parsing operates on portions of the input data set having a size less than a threshold size and leaves portions of the input data having a size greater than the threshold size unparsed. The intermediate output is parsed to convert at least one unparsed portion from the first format to the second format in a final output to complete the conversion such that a combined parsing time of the partial parse of the input data set and the parse of the intermediate output is accelerated relative to a single-stage parsing.Type: GrantFiled: September 8, 2016Date of Patent: December 31, 2019Assignee: International Business Machines CorporationInventors: Safa Messaoud, Takeshi Ogasawara
