A method and a device for realizing a screen projection service

Abstract

The invention provides a method and device for realizing a screen projection service, and the method comprises the steps: receiving a response message sent by a screen projection server in a network according to an inquiry request message, and determining whether a binding relationship between the screen projection server and a preset configuration exists or not according to an identifier of the screen projection server in the response message; if the binding relationship does not exist, adding the binding relationship corresponding to the identifier of the projection screen server, and addingthe identifier of the projection screen server and the binding relationship into a server resource table; receiving a screen projection service request sent by the terminal; determining a first binding relationship corresponding to the terminal identifier in the binding relationship according to the terminal identifier in the screen projection service request, and determining a first screen projection server table in the server resource table according to the first binding relationship; and sending the first projection screen server table to the terminal, so that the terminal selects the projection screen server in the first projection screen server table according to the first binding relationship. The problem of the accuracy of selecting the projection screen server by the terminal is solved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for realizing screen projection service. Background technique [0002] As corporate office networks become more and more wireless, corporate conference rooms are also developing towards digitization and mobility. Most corporate conference rooms now have abandoned the traditional presentation method of computer host + projector, which is cumbersome to operate. Adopt a more secure and convenient terminal + server + AirPlay screen presentation method. AirPlay is a playback technology added by Apple in iOS4.2 and OS X Mountain Lion, which can transmit the video image on the terminal (requires OS X Mountain Lion) to devices that support AirPlay (such as speakers, Apple TV) play. The use of AirPlay requires iOS4.2 version of the device. Video mirroring requires iOS 5 and OS X Mountain Lion. [0003] At present, in addition to the official screen projection serv...

AI Technical Summary

Problems solved by technology

[0011] The operation of the terminal is complicated, and most of the screen projection servers pushed by the traditional Bonjour Gateway are not within the scope of the user terminal. For example, there is a screen projection server in the meeting rooms on the 1st floor and the 2nd floor. The projection server in the conference room on the first floor is actually a useless service, but it will still be pushed to the selection list of the user terminal; in actual use, there are only 1-3 projection servers within the scope of the user terminal. The screen projection server that is not within the range of the user terminal occupies a large number of terminal selection lists, which is not conducive to user terminal selection, increases operational complexity, and reduces user experience
