Technical Field
The invention belongs to the technical field of screen projection, and particularly relates to a media resource screen projection method, equipment and system.
Background
The wireless screen projection technology is a technology of projecting the picture of the front-end equipment needing screen projection to the screen-projected terminal equipment for display. When the screen projection terminal plays the video in the browser, the video is played by calling a player of the system. However, when the screen is projected during browsing and playing, the screen projection protocols of the terminal device and the front-end device are different, so that the receiving end cannot implement screen projection playing. Taking the IOS system as an example, when playing a video, the Safari browser of the IOS system calls a system player, and the system player has an AirPlay screen-casting function and can cast a screen to an Apple TV or a receiving-end player with an AirPlay screen-casting protocol for screen-casting playing. However, if there is no Apple TV or no video player receiving AirPlay screen projection protocol on the terminal device, screen projection cannot be realized. Similarly, the Android system browser also needs the same protocol player for the screen projection terminal during video playing, otherwise screen projection playing cannot be realized.

and the screen projection module is used for projecting the media network address to the screen projection terminal.
The information receiving module receives a screen-casting information request and a webpage display request of a user, the address analyzing module analyzes a media network address, and when the screen-casting information request is received, the network address is sent to a screen-casting terminal through the screen-casting module to be subjected to screen-casting playing. By adopting the equipment, the same screen projection protocol with the terminal equipment is not needed, and the problem that the video screen projection in the browser needs protocol matching is solved.
A media resource screen projection device comprises an intelligent terminal, wherein an application program is arranged in the intelligent terminal, and the application program carries out screen projection response according to the method.
