  • Patent number: 11997366
    Abstract: An adaptive multi-view streaming processing method and apparatus for a multi-view stream is disclosed. Specifically, disclosed herein is a method and apparatus for adaptively processing or transmitting adaptive streaming by reflecting network states and changes in transmission environments in a multi-view streaming service environment where several or more multiple videos are simultaneously transmitted at an arbitrary moment. An adaptive streaming processing method for a multi-view stream may comprise selecting and downloading an i-th segment of a main view stream with a first quality level, inferring a size of an i-th segment of downloadable neighboring view streams based on a download time and transfer rate of the i-th segment of the main view stream, and selecting a second quality level corresponding to the inferred size of the i-th segment of the neighboring view streams and downloading the i-th segment of the neighboring view streams based on the selected second quality level.

  • Patent number: 11984057
    Abstract: A display device includes a display panel, controller configured to generate a second data enable signal and second image data based on a first data enable signal and first image data, and generate an output data enable signal and output image data by performing a black data insertion operation, and data driver configured to provide data signals based on the output data enable signal and the output image data, where the controller obtains a delay time between the first data enable signal and the second data enable signal or the first image data and the second image data, determines a number of subsequent pulses of the output data enable signal during a period from one time point within a frame period to an end time point of the frame period, and adjusts a cycle of the subsequent pulses based on the delay time and the number of the subsequent pulses.

  • Patent number: 7913857
    Abstract: A selective membrane having a high fouling resistance. In one embodiment, the selective membrane is a composite polyamide reverse osmosis membrane in which a hydrophilic coating is applied to the polyamide layer of the membrane, the hydrophilic coating being made by covalently bonding a hydrophilic compound to residual acid chlorides of the polyamide membrane, the hydrophilic compound including (i) at least one reactive group that is adapted to covalently bond directly to the polyamide membrane, the at least one reactive group being at least one of a primary amine and a secondary amine; and (ii) at least one non-terminal hydroxyl group.
