Publication number: 20240137585Abstract: In some embodiments, a method sends a set of first requests for a set of first segments of a video in a playback session. A first protocol from a plurality of protocols is specified in at least one of the set of first requests. The set of first segments is received. The method determines whether to switch from using the first protocol to a second protocol in the playback session based on receiving the set of first segments. When switching to the second protocol, the method sends a second request in the playback session, wherein the second request indicates the second protocol is to be used to send a second segment of the video.Type: ApplicationFiled: January 2, 2024Publication date: April 25, 2024Applicant: HULU, LLCInventors: Tongyu Dai, Lan Xie, Wenhao Zhang, Deliang Fu, Chao Li, Qiang She, Yuting Gui, Yicheng Liu, Yanping Zhou, Xizhi Xu

Patent number: 11956460Abstract: In some embodiments, a method selects a first template of pixels that is outside of a first block and a second template of pixels that is outside of the first block. Then, the method selects a first region of pixels that are inside the first block and a second region of pixels that are inside the first block. A first weight is calculated based on the first template of pixels and the first region of pixels and a second weight is calculated based on the second template of pixels and the second region of pixels. The first weight and the second weight are used in a motion prediction search for a second block.Type: GrantFiled: August 29, 2019Date of Patent: April 9, 2024Assignee: HULU, LLCInventors: Wenhao Zhang, Deliang Fu, Chen Liu, Xiaobo Liu

Patent number: 11930196Abstract: A method includes transcoding a first block from a spatial region. The first block is associated with a first block tree pattern defining a structure of splitting a block into smaller blocks. A bit string of bits for the first block tree pattern is included in an encoded bitstream. The method determines a location of the first block in the spatial region when the first block tree pattern of the first block can be reused for a second block tree pattern of a second block. The spatial region includes blocks and the location is based on the first block being in the spatial region. Information for the second block is included in the encoded bitstream that indicates the location of the first block in the spatial region. The location allows the bit string for the first block tree pattern to be retrieved for use to decode the second block.Type: GrantFiled: February 3, 2023Date of Patent: March 12, 2024Assignee: HULU, LLCInventors: Wenhao Zhang, Deliang Fu, Min Gao, Juncheng Ma, Chen Liu

Patent number: 9347152Abstract: A frictional false twister is disclosed. The twister has a plurality of rotating friction plates located between the nip of the front rollers and the yarn guide. The friction plates are staggeringly arranged for rubbing a twisted yarn. The spinning direction of the twisted yarn is opposite to the rotating direction of the friction plates. Through the action of the frictional false twister, the twist of the yarn between the false twisting device to the front nip can be increased, shortening the twisting triangle height, and increasing the spinning strength. As the yarn and the outer surface of the friction plate make relative sliding and rubbing, the friction damping force correspondingly reduces the spinning tension in the twisting triangle.Type: GrantFiled: February 16, 2012Date of Patent: May 24, 2016Assignee: Shanghai Wool & Jute Textile Research InstituteInventors: Lei Fang, Deliang Zhang, Linyao Wang, Xihui He, Wenhua Zhou, Yun Song, Shimin Liao, Ziyi Dai, Hongyan Lan, Genda Hua, Xiaoyan Wan

Patent number: 6264719Abstract: Titanium based metal matrix composites reinforced with ceramic particulate are well known, based on a blend of titanium alloy powders with ceramic powders, e.g., aluminum oxide powders, utilizing a low energy ball milling process, followed by cold compacting and sintering to produce an appropriate composite. This prior art process is disadvantaged from the point of view that there are virtually no particles in the blend below the micrometer size range, which lack has a deleterious effect on the subsequent processing of the composite. This problem has been overcome by utilizing dry high energy intensive milling in the process, which has the effect of providing the necessary number of small particles below the micrometer size range as well as enhancing the reactivity of different particles with one another.Type: GrantFiled: February 16, 2000Date of Patent: July 24, 2001Assignee: Titanox Developments LimitedInventors: Deliang Zhang, Martyn Rohan Newby
