  • Method for providing video streaming service and mobile device for same
    Patent number: 10631030
    Abstract: A technique for providing a video streaming service is provided. A method of a mobile device for providing a video streaming service includes sending periodically location and moving path information of the mobile device to a first server, receiving bitrate information per location predicted according to a moving path of the mobile device, from the first server, determining a bitrate for a current location of the mobile device based on the predicated bitrate information per location of the mobile device, and requesting a second server to send video segments based on the bitrate.
    Type: Grant

    Date of Patent: April 21, 2020
    Assignees: Samsung Electronics Co., Ltd., Seoul National University R&DB Foundation
    Inventors: Hyung-Ho Lee, Taekyoung Kwon, Han-Na Lim, Dookyoon Han, Ji-Cheol Lee, Youngbin Im, Taejoong Chung
  • Method and apparatus for assigning video bitrate in mobile communication system
    Patent number: 9398337
    Abstract: An embodiment provides a method for supporting video transmission and reception in a bitrate selection server of a mobile communication system. The method includes receiving a metadata request of a video from a terminal. The method also includes transmitting the received metadata request to a media server based on the request; receiving a metadata response from the media server. The method also includes storing the received video metadata and transmitting the received video metadata to the terminal. The method also includes requesting subscriber information of the terminal to a Policy and Changing Rules Function (PCRF) and receiving the subscriber information. The method also includes receiving a video segment request of the video from the terminal. The method also includes determining a bitrate of the video based on at least one of the video metadata and the subscriber information.
