In the big data age, data is needed to be used for speaking, the screen projection is a very effective data visualization carrier and a transmission tool, the main stream of screen projection solutions mainly comprises DLNA (digital living network alliance), the DLNA supports various devices, meanwhile, the characteristic of pushing data by using a streaming media server also enables the technology not to influence the normal use of control end devices, namely, the DLNA supports non-mirror image screen projection, and the screen projection solution with high use frequency is adopted. The screen-throwing technology of the DLNA mainly comprises three types of equipment, namely a control point, a media server and a media renderer, the DLNA defines equipment interaction specifications on the basis of a UPnP protocol, the equipment is communicated through an HTTP technology, and specification information of the equipment is published to other nodes in an XML mode. The control point is typically a smart phone that does not participate in the media transfer process and is primarily used to coordinate the interoperation functions between the media server and the media renderer. The control point realizes the screen-throwing interaction process as follows: the control point searches the media server and the media renderer in the local area network, automatically detects the media server and the media renderer in the network, acquires multimedia information by calling a content directory service interface provided by the media server, and returns directory and file information including supported transmission protocols and formats. The control point then invokes the interface of the media renderer to obtain the list of transport protocols and supported data formats, and selects both supported protocols and data formats by comparison. The control point selects the multimedia material to be presented, the audio and video transmission service interface of the media server is called to tell the media presenter of the resource storage address, the media presenter downloads the resource from the media server to start screen projection, and when the screen projection is hoped to be finished, the control point calls the interface of the media server to inform the media server to finish screen projection.

If videos and photos on the mobile phone are projected onto a television, convenience of sharing and spreading of multimedia data is improved to a certain extent, advantage complementation of the mobile terminal and a large display screen is effectively improved, however, the existing scheme also has obvious limitations. Firstly, in a network environment, devices participating in screen projection are required to be located under the same local area network or even the same route. In reality, the screen-throwing device may not be in the same local area network, for example, wifi is connected to a television, 5G is possibly connected to a mobile phone, and the situation that the device cannot be found and connected cannot occur due to the screen-throwing scheme of the local area network. Secondly, the existing screen projection scheme manufacturers often customize a private transmission protocol at an application layer, and the equipment participating in screen projection needs to support a specific protocol (such as a connection management protocol in DLNA), which increases the complexity and implementation cost of the screen projection scheme. And then the control end sends private instructions to the media server and the media presenter to control the behavior and state conversion of the equipment. The number of devices that can be mounted on the control side is limited in view of the resource consumption and load pressure for establishing a long connection channel. The screen-throwing connection method in the prior art has the technical problems of high connection requirement, high difficulty and complex realization.
