Problems solved by technology

[0003] At present, there are many software for network transmission, but most of them can only use a fixed transmission protocol in one or a few network environments, or need to manually select a specific transmission protocol to complete the data transmission process, which is not intelligent enough
Existing software also uses multiple TCP connections to complete data transmission, but they either set a fixed number of links internally, or manually set the numbe

Embodiment 1

[0031] An embodiment of an intelligent and efficient video and audio data transmission method adapted to different network environments, see figure 1 , figure 2 , image 3 and Figure 4 , the method transmits the video and audio data from the video and audio data sender to the receiver through the Internet. The process is to first obtain the real-time parameters of the network environment, obtain the network delay threshold and the network packet loss rate threshold, and judge and select the data transmission strategy according to the real-time parameters ,like figure 1 The flow steps of the method shown are:

[0032] a. The program starts to detect the real-time parameters of the current network environment; that is, the real-time parameters of the network environment are obtained in real time, and the real-time parameters include: network packet loss rate, network delay and path maximum transmission unit;

[0033] b. According to the detected real-time network performan...

Embodiment 2

[0050] A preferred embodiment of an intelligent and efficient video and audio data transmission method adaptable to different environments, see Figure 5 , Figure 6 and Figure 7 , and Embodiment 1, due to adapting to various network environments, and taking into account the use of various transmission protocols, as well as the real-time and sequential requirements of the video and audio data application business, in order to facilitate the upper layer application call, the video and audio data The transport layer and the binary data transport layer are preferably transparent to each other. In view of this, a layered design is adopted in the implementation process. The transmission method is composed of a video and audio data transmission layer and a binary data transmission layer. The layer provides interfaces; the video and audio transport layer is implemented on the basis of the binary transport layer, provides logic directly related to video and audio formats and applic...

Abstract

The invention relates to an intelligent efficient video/audio data transmission method adapted to different network environments, which comprises the following steps of: adjusting the data in real time according to a network state, and when a network packet loss rate is more than a threshold value, adopting a UPD protocol of a path maximum transmission unit to transmit the data; when the network packet loss rate is less than the threshold value and a network delay is more than the threshold value, adopting a TCP+UPD protocol to transmit the data; and when both the network delay and the network packet loss rate are less than the threshold value, adopting a TCP protocol to transmit the data. A layered design is adopted, namely, a binary transmission layer packages all the network transmission details; and a video and audio transmission layer is packaged on the binary transmission layer; all the logics correlated with video and audio are realized in the video and audio transmission layer. Therefore, a caller can realize the transmission of frame levels of the video and audio of a file by only appointing the media file required to be transmitted so as to greatly simplify the use of the superior caller; and a video and audio service intelligently selects a transmission strategy to finish the real-time transmission of video and audio data and to obtain efficient transmission performance according to the real-time characteristics of a network.

Description

technical field [0001] The invention relates to an intelligent and efficient video and audio data transmission method adapting to different network environments. It is a video and audio data transmission method that measures the network status by irregularly sending detection packets and receiving feedback, and timely adjusts the video and audio data according to the current network status. . Background technique [0002] With the rapid development of WAN, the network is widely and deeply used in business application systems, and more and more video and audio business systems will also be deployed and used across WANs. However, different networks such as packet switching networks (Ethernet), wireless networks, 3G mobile communication networks, and some high-speed private networks have significantly different network characteristics. The congestion status of the entire network changes with the current network traffic. The performance of the network service that comes out wil...
