3. using a real-time monitoring audio and video streaming RTSP URL (realRtspURL) address, a voice talkback RTSP URL (audioRtspURL) address and a clientID as parameters, and initiating a monitoring platform gateway task (as a task) to a gateway service;
in this embodiment, the gateway service logic includes:

4. using the audioRtspURL address to initiate a voice talkback request to the video monitoring platform, sending a conference audio stream to the monitoring platform, and sending the received audio stream to the conference system;
in the embodiment of the invention, the gateway uses the RTSP URL address of the real-time monitoring audio and video stream to send a request for acquiring the real-time monitoring audio and video stream to the video monitoring platform; after the real-time monitoring audio-video stream is obtained, the audio stream is discarded, and the obtained video stream is sent to a conference system in the mode of simulating the identity of a terminal; the gateway initiates a voice talkback request to the video monitoring platform by using the voice talkback RTSP URL address, sends the conference audio stream to the monitoring platform, and sends the audio stream received from the monitoring platform to the conference system. The real-time monitoring audio and video streaming RTSP URL address and the voice talkback RTSP URL address of a monitoring camera in a monitoring platform are used as parameters of the same gateway task and are accessed by using the same simulation terminal, so that the real-time monitoring audio and video streaming access and the two-way voice call of the monitoring camera are realized; the voice talkback uses an independent channel for transmission, so that the real-time performance of the voice talkback is ensured; the method solves the problem that the transmission of the video stream can influence the audio stream and can not realize the logic of 'audio priority' when the audio and video stream is transmitted in one channel. The other ideas are as follows: an RTSP URL address corresponding to a monitoring camera can be adopted to correspond to a simulation terminal device in a video conference, a video conference participant is simulated, and a one-to-one mapping relation is formed. Therefore, when a monitoring camera provides an RTSP URL address for pulling real-time audio and video streams and an RTSP URL address for voice talkback, how to realize conference control becomes a difficult problem. Or the other realization method is that two RTSP URL addresses of one monitoring camera can be adopted to correspond to two simulation terminals in the video conference to simulate two conference participants. At this time, conference control (e.g., turning off the camera and turning off the speaker) for one monitoring camera in the conference system becomes very troublesome, and user experience is poor.
The embodiment of the invention effectively overcomes the two problems. In the monitoring platform of the embodiment of the invention, in order to ensure the voice talkback effect, the platform respectively uses different addresses for acquiring the audio and video stream and initiating the voice talkback, so that the two-way call with the monitoring camera is realized while the monitoring video stream is acquired, and the technical trouble caused when the video conference system is in butt joint with the monitoring platform and uses two addresses is overcome.
Specifically, a large number of monitoring cameras are managed in the video monitoring platform, and most of the monitoring cameras can acquire monitoring videos and can perform voice talkback. In order to ensure the voice talkback effect, the monitoring platform of the embodiment of the invention provides two RTSP URL addresses, wherein one RTSP URL address is used for pulling the real-time monitored audio/video stream, and the other RTSP URL address is used for the voice talkback of the camera and comprises one path of uplink audio stream and one path of downlink audio stream. The receiving and sending of the voice talkback audio stream are based on the independent network channel, the video stream can be prevented from influencing the sending of the audio stream, and the timeliness of the voice talkback is improved.
Therefore, the embodiment of the invention realizes the butt joint of a plurality of RTSP URL addresses of one monitoring camera of the monitoring platform in the conference system, pulls the real-time monitoring audio and video stream of the monitoring platform into the conference system, and simultaneously realizes the bidirectional communication with the monitoring camera. Two RTSP URL addresses of the monitoring camera correspond to one participant of the conference system, so that the conference system is convenient and natural to control, and the user experience is greatly improved. And the independent RTSP URL address and the monitoring camera are used for voice talkback, so that the implementation of an audio priority strategy is ensured, and the conference conversation quality with the monitoring camera is ensured.
Of course, the present invention may also be applied to other electronic devices with video functions, such as a tablet, a mobile phone, and the like, and the electronic devices with video functions are within the protection scope of the present invention as long as the electronic devices can separate audio and video streams into two independent channels for transmission.
