Abstract

The invention is applicable to the field of streaming media, and provides a streaming media transmission method and a streaming media transmission system. The streaming media transmission method comprises the following steps: a first SIP (session initiation protocol) terminal and a second SIP terminal are registered in an SIP server through an NAT (network address translation) penetrating technology; the first SIP terminal acquires an SDP (session description protocol) containing a second candidate address table and sent by the second SIP terminal so as to generate a candidate address pair table; the second SIP terminal acquires an SDP containing a first candidate address table and sent by the first SIP terminal so as to generate another candidate address pair table; according to candidate address pairs provided by the candidate address pair tables, the communication between the first SIP terminal and the second SIP terminal is tested by an NAT penetrating technology so as to generate a communicating address pair table; according to the communicating address pair table, mutual streaming media transmission is performed.

Description

technical field [0001] The invention belongs to the field of streaming media, and in particular relates to a streaming media transmission method and system. Background technique [0002] The Signaling Control Protocol (Session Initiation Protocol, SIP) works at the session layer. The SIP protocol provides real-time multimedia communication services in the Internet Protocol (IP) network interconnected between networks; and, the SIP protocol has become the next generation It is one of the important standards adopted by the Next Generation Network (NGN), and also serves as one of the key protocols of the softswitch system. In addition, the SIP protocol has good scalability properties, can easily add definitions, and can also be embedded in various user terminals to achieve new functions; therefore, the SIP protocol has strong interoperability, good development and expansion characteristics, while promoting the development of unified communications. [0003] Using SIP to estab...
