  • Patent number: 10741186
    Abstract: Embodiments of the present disclosure provide a decoding method and a decoding apparatus. The decoding method includes: in a case in which it is determined that a current frame is a lost frame, synthesizing a high frequency band signal; determining subframe gains of multiple subframes of the current frame; determining a global gain of the current frame; and adjusting, according to the global gain and the subframe gains of the multiple subframes, the synthesized high frequency band signal to obtain a high frequency band signal of the current frame. A subframe gain of the current frame is obtained according to a gradient between subframe gains of subframes previous to the current frame, so that transition before and after frame loss is more continuous, thereby reducing noise during signal reconstruction, and improving speech quality.

  • Patent number: 10739863
    Abstract: A mobile terminal detects a gesture on a touchscreen; when a pressure value of the gesture exceeds a first threshold P1, starts to record change information of the pressure value of the gesture; when the pressure value is lower than a second threshold P2, stops to record the change information of the pressure value; parses the recorded change information of the pressure value; when the parsing of the change information indicates that the gesture includes at least two consecutive effective screen presses, determines that the gesture matches a first instruction; and in response to the first instruction, presents a first graphical user interface on the touchscreen. In this manner, press gesture identifying precision can be improved, and a problem that it is difficult for the touchscreen to distinguish a long press from the press gesture can be avoided.
