  • Patent number: 11450437
    Abstract: The present disclosure provides a method, an apparatus, and a system for health management. The method includes: receiving, from a graphical interface of a first user terminal, login information of a first user account, the first user terminal having a memory, a processor, and a measurement sensor; obtaining, by the first user terminal, physiological data of a user based on a measurement value detected by the measurement sensor; storing the physiological data into a medical record corresponding to the first user account; and sending, by the first user terminal via a server, the physiological data to a second user terminal associated with the first user account remotely.
    Type: Grant
    Filed: December 13, 2017
    Date of Patent: September 20, 2022
    Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITED

  • Patent number: 8861372
    Abstract: The present invention discloses a method and a device for fast pushing a unicast stream in a Fast Channel Change (FCC), and relates to the field of Internet Protocol Television (IPTV). A server obtains a multicast join delay of a terminal, determines a minimum value of a data amount between a starting position of a fast unicast stream and a latest packet position according to the multicast join delay of the terminal, a decoding rate, a unicast push rate, and a lowest buffer data amount required for decoding, judges whether a latest I frame completely arrives according to a packet buffer state; and fast pushes the unicast stream starting from the latest I frame if the latest I frame completely arrives, and an arrived data amount starting from the latest I frame is greater than or equal to the minimum value.
