Problems solved by technology

[0005] The above is an example of a monitoring client ordering one live stream. If multiple cameras are performing live ordering services at the same time, STUN detection and STUN traversal need to be repeated. Repeating the STUN detection process will introduce more additional delays. The real-time requirements of the monitoring business are affected, and the efficiency of the monitoring business is very low

Abstract

The invention provides a method and device for playing multiple media streams on demand. The method comprises the steps that a first service link is used for sending a target channel media stream service establishing informing report to a video monitoring client-side, wherein the service establishing informing report carries a private network IP address of video monitoring equipment, an expected private network port number, a public network IP address converted by NAT gateway equipment and an expected public network port number; a service stream guiding report sent to the public network IP address and the expected public network port number by the video monitoring client-side is received and a second service link for the video monitoring equipment and the video monitoring client-side is established, wherein the stream guiding report carries a target channel identifier; the second service link is used for sending media streams of a target channel to the video monitoring client-side. By means of the method and device for playing the multiple media streams on demand, the perforating process of STUN is omitted and the service monitoring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a multi-channel media stream on-demand method and device. Background technique [0002] In order to save the number of public network IP addresses and protect private network security, operators will deploy NAT (Network Address Translation, Network Address Translation) gateway devices at the egress of private networks. The addresses are converted to each other. Among them, the NAT gateway device can convert multiple private network IP addresses into the same public network IP address, and only need to use different port numbers after conversion to distinguish the corresponding private network IP addresses. Such as figure 1 As shown, the NAT gateway device can convert (IP1, Port1), (IP2, Port2), (IP3, Port3) in the private network to (IPA, PortA1), (IPA, PortA2), (IPA, PortA3). [0003] Taking the video surveillance field as an example, the video surveillance client an...
