Problems solved by technology
However, before the video call is established, there is a problem that the video image of the IP extension terminal cannot be viewed in advance, which is not conducive to precise command and dispatch
For example, when multiple IP extension terminals call the IP audio and video dispatching station at the same time, when the IP audio and video dispatching station has not yet connected to the video, because the video images of the IP extension terminals cannot be viewed in advance, it is not possible to arrange priority connection video call
Another example is that when the IP audio and video dispatching station broadcasts the IP extension terminal, if no one connects to the IP extension terminal, the IP audio and video dispatching station cannot view the video image of the IP extension terminal, and cannot view the surrounding scene information of the IP extension terminal.
These problems will affect communication scheduling, which is not conducive to safe production

Embodiment Construction
[0012] The drawings in the embodiments of the present invention will be combined below. See figure 1 , A method for viewing terminal video based on SIP video call. The video call system adopts C / S architecture model. The main functional modules include IP audio and video dispatching station, multimedia communication platform and IP extension terminal, IP audio and video dispatching station and IP extension terminal The SIP protocol stack module, audio and video acquisition module, audio and video transmission processing module, and audio and video playback and rendering module are integrated inside; when the IP extension terminal initiates a video call to the IP audio and video dispatching station, the SIP protocol stack module sends INVITE messages, And process the PRACK message to realize the establishment of an early one-way audio and video media stream session with the IP audio and video dispatching station; the IP extension terminal initializes the local video acquisition f...

The invention discloses a method for viewing terminal video based on a SIP video call. The video call system adopts a C / S architecture model. When an IP extension terminal initiates a video call, the SIP protocol stack module sends an INVITE message and processes a PRACK message to realize Establish an early one-way audio and video media streaming session with the IP audio and video dispatcher. According to the SDP information, the IP extension terminal displays the video image through the audio and video playback display module, and the IP audio and video dispatcher can view the extension video in advance. The present invention is beneficial to the precise scheduling of the IP audio and video dispatching station. Regardless of whether the dispatching station is the calling party or the called party, before establishing a two-way conversation between the two parties, the video code stream of the incoming terminal is directional obtained at the IP audio and video dispatching station end, so that it can be viewed in advance. The video image of the incoming terminal is convenient for the IP audio and video dispatching station to give priority to connecting the call line according to the number and importance of incoming calls to achieve precise dispatching.
Description
Technical field [0001] The invention relates to the field of multimedia communication dispatching, in particular to a method for viewing terminal video based on SIP video calls. Background technique [0002] Video call is a conversation method that can realize simultaneous voice and video communication with multiple people. Through video calls, users in multiple different locations can speak face-to-face and view the other party's video images, quickly convey voice and video image information to the other party, and improve communication efficiency. Due to the inherent advantages of video calls, this technology has been widely used in various fields. Of course, the requirements of various industries on the quality of audio and video communication and communication effects are becoming more and more stringent. [0003] SIP (Session Initiation Protocol) is a multimedia communication protocol that can be well supported and applied to multimedia communication sessions such as voice, v...
