摘要： 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. According to the embodiments of the present invention, when the network time delay changes, time for playing the received media frames may be adjusted by changing number of blank frames in the received but not played media frames, so as to reduce or eliminate the effect on the real-time media service generated by the network time delay characteristics.
