Problems solved by technology

The transmission of streaming media data on the Internet relies on network transmission protocols, including TCP and UDP transmission protocols. If multimedia data is transmitted with a protocol that does not have any sorting, retransmission and congestion control, the network bandwidth will be exhausted rapidly, and with The deterioration of the network status and the increase in the number of lost packets will also affect the transmission quality
The existing congestion control is not suitable for embedded devices with limited hardware conditions. It has not been adjusted according to the characteristics of embedded devices, and cannot meet the real-time and accuracy of streaming media data in embedded devices.
Therefore, for the above-mentioned problems existing in related technologies, effective solutions have not yet been proposed

Abstract

The present invention provides a method for controlling the data transmission rate. The method includes: the streaming media server measures the QoS index and judges the current network congestion situation; Latency controls network throughput. The invention provides a transmission control method aimed at streaming media servers with limited hardware conditions, improves the real-time performance and effectiveness of streaming media transmission, effectively adjusts the transmission rate, and significantly improves QoS.

Description

technical field [0001] The invention relates to network transmission and communication, in particular to a streaming media transmission method. Background technique [0002] In recent years, with the rapid development of the Internet and information technology, as well as the combination of servers and the Internet, how to optimize network protocols, efficiently transmit multimedia data under limited network bandwidth, and avoid network congestion has become an important issue for video and voice One of the development directions of media servers. The transmission of streaming media data on the Internet relies on network transmission protocols, including TCP and UDP transmission protocols. If multimedia data is transmitted with a protocol that does not have any sorting, retransmission and congestion control, the network bandwidth will be exhausted rapidly, and with The deterioration of the network status and the increase in the number of packet loss will also affect the tra...
