Embodiment Construction

[0053] The present invention provides a real-time media stream transmission method and system. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] see figure 1 , figure 1 It is a flowchart of a preferred embodiment of the real-time media stream transmission method of the present invention, as shown in the figure, which includes steps:

[0055] S101. The server side judges whether the data frame of the media stream to be transmitted is a key frame. When it is judged that the data frame is a key frame, the data frame is split into data packets and a key frame identifier is added to the data frame to become a key. frame packet;

[0056] S102. Send the key frame packet to the client, and monitor whethe...

Abstract

The present invention discloses a real-time media stream transmission method and system, wherein the method comprises the steps of: judging whether the data frame of the media stream to be transmitted is a key frame at the server end, and when judging that the data frame is a key frame, sending the data When the frame is divided into data packets, a key frame identifier is added to the data frame to become a key frame packet; the key frame packet is sent to the client, and whether the client returns the confirmation information of receiving the key frame packet ; When the server does not listen to the confirmation information returned by the client within a predetermined time, resend the key frame packet to the client. The invention effectively reduces the packet loss rate in the transmission process, ensures the integrity of the key frame, improves the decoding effect of the media stream on the client side, and does not cause too much network load burden at the same time.

Description

technical field [0001] The invention relates to the field of information transmission, in particular to a real-time media stream transmission method and system. Background technique [0002] In current multimedia applications, real-time transmission of media streams is more and more widely used, such as video conferencing, same-screen display and so on. Since real-time media streaming has the characteristics of high bandwidth occupancy rate, low packet loss rate, and high real-time performance, the requirements for the network environment are relatively high. When the network environment is unstable, the user experience is often relatively poor. [0003] The existing process of real-time transmission of media streams is generally: 1. Server side: raw data collection, encoding, and data transmission; 2. Client side: data reception, decoding, and display. In the transmission process, in order to ensure the real-time transmission, it is usually realized by using the method of ...
