Abstract:
1. A method for processing network time delay characteristics, comprising: determining whether network time delay changes; if the network time delay reduces, determining whether at least one blank frame is comprised in received but not played media frames of a real-time media service; if at least one blank frame is comprised in the received but not played media frames of the real-time media service, extracting the blank frame from the received but not played media frames, wherein 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; wherein determining whether the network time delay changes comprises, obtaining a time-delay litter prediction value, wherein the time-delay litter prediction value is a time interval between a time for extracting a media frame for playing and another time for receiving a media frame last time, obtaining a playing duration needed for playing the received but not played media frames, calculating a difference between the time-delay litter prediction value and the playing duration, comparing the difference with the preset first threshold, if the difference is larger than the first threshold, determining the network time delay increases, comparing the difference with the preset second threshold, and if the difference is smaller than the second threshold, determining the network time delay reduces.
