Method, device and system for transmitting streaming media data in restricted networks

Abstract

The invention discloses a method, device and system for transmitting streaming media data in restricted networks, which relate to the technical field of communications, can be used for transmitting the streaming media data to a destination end in the presence of restricted conditions, have high reliability, and are used to realize the successful transmission of the streaming media data in the restricted networks. The method for transmitting the streaming media data in the restricted networks comprises the following steps: carrying out capsulation on the datagram of a user datagram protocol (UDP) of the steaming media data by an internet client-side to obtain data streams of a transmission control protocol (TCP); sending the data streams of the TCP to an internet server by the internet client-side through a TCP connection between the internet client-side and the internet server; carrying out reverse decapsulation on the data streams of the TCP to obtain the datagram of the UDP by the internet server; sending the datagram of the UDP to a telecommunication gateway device in a telecommunication network by the internet server; and sending the datagram of the UDP to a corresponding telecommunication client-side by the telecommunication gateway device.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission method, device and system for stream media data in a restricted network. Background technique [0002] Streaming Media (Streaming Media) is a technology that uses streaming technology to transmit multimedia files on the network to provide users with online services. Due to the advantages of being able to generate multi-bandwidth audio and video content in real time and being suitable for users with different access methods, the streaming media industry has developed vigorously. [0003] When streaming media data is transmitted on the Internet, a bearer mode based on User Datagram Protocol (User Datagram Protocol, UDP) data packets is usually adopted. [0004] Moreover, with the development of Internet technology applications, the Internet has begun to try to communicate with the telecommunications network; in the current real-time communication tech...

Problems solved by technology

[0005] However, there are also many deficiencies in the existing technology. For example, the existing streaming media data transmission method does not take into account the complexity of the Internet system. For restricted networks with restrictions, such as networks with limited UDP transmission In the network of firewalls or routing devices, when UDP data packets are used for streaming media data transmission in this network, the streaming media data will often be filtered by the network, resulting in the streaming media being unable to be transmitted to the destination, and the transmission reliability is low.
