The invention relates to the technical field of data transmission, in particular to a multimedia data stream transmission method and device, and solves the problems that due to the fact that a multimedia data stream cannot be acquired from a cluster chip in a server by using a point-to-point method and the same path of multimedia data stream may be repeatedly utilized by the server, the redundancy in connection and bandwidth use is caused. The method comprises the following steps: when a master cluster chip in a server receives a multimedia information acquisition request sent by a corresponding slave cluster chip, sending the multimedia information acquisition request and a relay port address of relay equipment to a national standard platform through the relay equipment; receiving a multimedia data stream forwarded by relay equipment based on a chip port address, and forwarding the multimedia data stream to at least one slave cluster chip through a master cluster chip, so that the master cluster chip can receive the multimedia data stream returned by a national standard platform and forward the multimedia data stream to at least one slave cluster chip; therefore, the matching transmission of the multimedia data stream to the slave cluster chip is realized.
Description
Technical field [0001] The present application relates to computer technology, and more particularly to transmission methods and apparatus for multimedia data streams. Background technique [0002] The security monitoring system rely on the camera to obtain real-time dynamics of the monitored object, in order to obtain a more comprehensive monitoring scenario, the number of cameras set in the security monitoring system is increasing. In most scenarios, audio and video information transmission between the camera and the backend processing equipment (including national standard platforms and X86 servers, etc.) is done by the National Standard GB / T28181-2016 (referred to as GB28181) of the People's Republic of China. [0003] GB28181 can meet the streaming requirements of X86 servers, namely, point-to-point transmission. Specifically, the camera transmits the collected multimedia data stream to the national standard platform, and then transmits each multimedia data stream to the n...
