Embodiment 1

[0034] Such as figure 2 As shown, in the embodiment of the present invention, the process of obtaining streaming media cache parameters is as follows:

[0035] S101. Obtain the video packets of the media stream, and calculate the throughput of the video packets during the transmission process;

[0036] In this embodiment, the executor is the network quality assessment platform located on the IP network side.

[0037] S102. Calculate streaming media cache parameters according to the throughput and the acquired video duration.

[0038] When the header of the video packet includes a time stamp, it is necessary to analyze the time difference recorded by the time stamp in the header of the video packet, and obtain the time difference recorded by the time stamp in the transmission control protocol TCP confirmation packet, and the time difference is respectively Indicates the corresponding time difference from the first to the last of the video packets at different time stamps. W...

Embodiment 2

[0046] image 3 is a flowchart of an embodiment of the present invention, such as image 3 As shown, the process of the embodiment of the present invention is as follows:

[0047] S201. Obtain a streaming media package;

[0048]The network quality evaluation platform obtains the streaming media package sent by the server by communicating with the streaming media server.

[0049] S202. Determine whether the time stamp can be parsed;

[0050] The network quality assessment platform analyzes the received streaming media packets and judges whether the time stamp can be resolved.

[0051] If there is a video playback timestamp in the video protocol header, or a timestamp set in the audio content for audio and video synchronization. Use these time points to mark the content of each package with a relative time point. For example, the arrival time of the first packet is T1, and the arrival time of the nth packet is Tn.

[0052] Since the streaming media packet is transmitted th...

Embodiment 3

[0076] Image 6 It is the structure diagram of the CSFB server, such as Image 6 shown, including:

[0077] An acquisition unit 301, configured to acquire video packets of media streams;

[0078] In this embodiment, the executor is the network quality evaluation platform located on the IP network side.

[0079] The calculation unit 302 is configured to calculate the throughput of video packets during the transmission process, and calculate streaming media buffer parameters according to the size of the throughput and the acquired video duration.

[0080] When the header of the video packet includes a time stamp, the calculation unit 302 needs to analyze the time difference recorded by the timestamp in the header of the video packet, and obtain the time difference recorded by the timestamp in the transmission control protocol TCP acknowledgment packet, so The time difference respectively represents the corresponding time difference from the first to the last of the video pack...

Abstract

The invention relates to a method for obtaining streaming media caching parameters. The method includes that a video package of media stream is obtained, and throughput capacity of the video package in a transmission process is calculated; and the streaming media caching parameters are calculated according to the throughput capacity and obtained video duration. Correspondingly, a network quality evaluation platform is provided, a problem of being large in difficulty in obtaining the streaming media caching parameters is solved, and the obtaining precision of the streaming media caching parameters is improved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a method and device for acquiring streaming media cache parameters. Background technique [0002] Streaming Media (Streaming Media) is a continuous audio / video data stream transmitted and played by streaming technology on the network. Streaming technology means that the server parses the entire multimedia file into multiple compressed packets through a specific compression method, and then transmits them sequentially or in real time to the user through IP, and the client opens up a buffer to receive the compressed packets. [0003] The streaming media system refers to a system that can provide streaming media services to end users through streaming technology. The basic architecture of the streaming media system consists of three levels: [0004] Streaming media production and server layer: provide streaming media live / recorded / on-demand content collectio...
