  • Publication number: 20230343345
    Abstract: A method for audio packet loss compensation processing includes: acquiring time domain signals of a first number of existing audio frames in a case that an audio packet loss occurs; carrying out acoustic feature extraction on the time domain signals of the first number of the existing audio frames to generate acoustic features of the existing audio frames; carrying out semantic feature extraction on the time domain signals of the first number of the existing audio frames, and carrying out semantic understanding based on the extracted semantic features to generate semantic expressions corresponding to the existing audio frames; and predicting a time domain signal of a current audio frame according to the acoustic features and the semantic expressions, for audio packet loss compensation.

  • Publication number: 20210112288
    Abstract: Embodiments of the present disclosure provide network live-broadcasting methods and devices. The method can include: obtaining live-broadcasting data from a server side; obtaining service data from the server side; determining whether the obtained live-broadcasting data contains key information, wherein the key information is inserted by a live-broadcasting side in the live-broadcasting data when predetermined content corresponding to the service data is included in the live-broadcasting data; and outputting, in response to receiving the key information, the service data on a playing interface of the live-broadcasting data, so that the service data is output synchronously with the predetermined content.
