Problems solved by technology

However, UDP transmission is an unreliable network transmission method without links
Its non-connectivity has caused its link instability during the transmission of a large amount of data, and the packet loss rate is extremely high, resulting in a decrease in transmission speed, low quality of streaming data, frequent packet loss during network transmission, and lack of video images. Many problems with frame phenomenon

Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] figure 1 It is a flow chart of the streaming media data transmission method according to the first embodiment of the present invention. like figure 1 As shown, the transmission method includes: S102, the sender saves the sent streaming media data in the sending queue while sending the streaming media data to the receiver; S104, the sender sends the streaming media data to the receiving party periodically Send all streaming data held in the queue.

[0021] Specifically, in figure 1 In the method shown, the sender first establishes a sending queue during the P2P streaming media data transmission process. Then, each time the sender sends a piece of streaming media data to the receiver, the sent streaming media data is inserted into the sending queue at the same time. Wherein, all streaming media data in the sending queue ...

Abstract

The invention discloses a method and a system for transmitting streaming media data. The transmitting method includes: a transmitting side transmits streaming media data to a receiving side, in the meantime, the transmitted streaming media data is saved in transmitting queue; the transmitting side transmits all streaming media data saved in transmitting queue to the receiving side by using first time as period. The method and system provided by the invention reduce packet loss condition in user data message protocol transmitting process, keeps transmitting speed of user data message protocol, ensures whole efficiency of received data, consequently, fluency and stabilization of video streaming media in playing process can be ensured.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a streaming media data transmission method and system. Background technique [0002] Most of the existing P2P streaming media live video and video-on-demand products use the Transmission Control Protocol (Transfer Control Protocol, TCP for short) to transmit data in streaming data transmission. Although the TCP protocol can ensure that the data reaches the terminal completely, the transmission speed on the Internet is relatively slow. More importantly, at present, 80% of the Internet users are in the intranet or firewall, and it is difficult for users to connect with each other through P2P. If users want to watch videos, they must be transmitted through the server, which cannot achieve the effect of P2P. A large amount of bandwidth of the server causes the server data to be blocked and the speed is slow, and the viewing effect of the client is not ideal, such as...
