description The invention discloses a real-time live TS stream de-jitter processing method and system. The processing method comprises the following steps: 1, monitoring code stream received by a player and acquiring the code rate of a current program; 2, dynamically pre-applying for data buffer space of a corresponding time length according to the code rate; 3, caching data and decoding; 4, judging whether the amount of data in the data buffer space is less than a preset threshold or not; if so, lowering audio and video rendering rate and increasing the threshold; otherwise, restoring to a normal audio and video rendering rate, and decreasing the threshold; and 5, returning to the step 1 to continue monitoring. Through adoption of the method and the system, the jitter influence of WiFi network transmission can be well eliminated; programs can be broadcast timely; the broadcasting stability is ensured for a long time; and the program viewing experience is improved. 本发明公开了种实时直播TS流的去抖处理方法及处理系统，其中处理方法包括步骤1，对播放器接收的码流进行监控并获取当
