Abstract: Embodiments of the present invention provide a method and device for processing network time delay characteristics. The method includes: determining whether network time delay changes; if the network time delay reduces, determining whether at least one blank frame is included in received but not played media frames of a real-time media service; if at least one blank frame is included in the received but not played media frames, extracting the blank frame from the received but not played media frames, the blank frame is a media frame, information amount of which is smaller than a preset first threshold, or difference between the information amount of which and the information amount of a previous media frame is smaller than a preset second threshold; if the network time delay increases, inserting the blank frame in the received but not played media frames.
