Embodiment

[0025] The processing method of streaming media buffering in this example adopts the following steps to realize: a. Capture video stream, analyze and obtain video stream code rate and network average rate; By recording the number n and the size of the data packets received in a certain period of time t b, the average network rate of the media stream can be calculated, namely Further, in order to smooth the jitter in the network transmission process, the sliding weighted average method is used to smooth the average network rate of the media stream, namely (0 is the last average velocity; v new is the average rate of the current sample.

[0026] b. Set three thresholds to divide the buffer zone into four intervals. The three thresholds are the lower warning line U1, the upper warning line U2, and the discarding warning line U3 from small to large. Among them, U1, U2, and U3 represent the buffer zone usage rate;

[0027] c. Calculate the maximum length of the buffer through ...

Abstract

The invention relates to web television streaming media technology, in particular to a processing method for streaming media buffer. The invention discloses a processing method streaming media buffer and solves the problem that a signaling feedback mode adopted for processing the synchronization of the streaming media in the prior art increases the burden of a server and affects the quality and efficiency of the video display. The processing method has the technical scheme that the processing method comprises the following steps: a. capturing video streaming, resolving and obtaining video streaming code rate and network average rate; b. setting three threshold values and dividing a buffer zone into four sections; c. computing the maximal length of the buffer zone and the usage rate of thecurrent buffer zone; d. carrying out on decoding play rate adjustment on a decoding playback module according to the section positions of the usage rate of the current buffer zone in the four sections of the buffer zone. The invention has the beneficial effects that the processing method can effectively relieve network time delay and vibration phenomenon and solves the clock drift problem, thus increasing the quantity and efficiency of the video play and being suitable for streaming media play.

Description

technical field [0001] The invention relates to network television streaming media technology, in particular to a streaming media buffering processing method. Background technique [0002] With the rapid development of network technology, the application of network video streaming services is becoming more and more extensive, including VOD (Video On Demand) and IPTV (Internet Television) gradually entering people's lives. These applications have high requirements on Qos (Quality of Service). In order to meet the requirements of playback quality, the end-to-end rate must be able to keep in sync. [0003] At present, for the synchronization problem of IP network media streams, a common solution is to use signaling feedback. The playback terminal sends corresponding "signaling" to the server, and the server adjusts the sending rate according to the received signaling, so as to adapt to the decoding and playback module of the playback terminal for decoding and playback. IPTV i...
