Problems solved by technology

[0006] In the existing technology, the user still needs to remotely transmit the projection data to the projector, and the operation is relatively complicated; at the same time, the computing and storage resources of the network projector itself are limited. Resources will be insufficient and cannot be adjusted dynamically or in real time; under special conditions such as conference room changes or projector replacements, data switching and copying of network projectors is required, which is complex and lacks flexibility; in addition, users need to transfer projection data to Into the projector, lack of security in terms of user data and corporate data management

Abstract

The embodiment of the invention discloses a projecting method, which comprises the following steps: a projector accesses a storage space corresponding to a user to acquire projecting data pre-stored in the storage space, wherein the storage space corresponding to the user is positioned outside the projector; and the projector converts the projecting data into a corresponding projecting signal, and projects and displays the corresponding projecting signal according to the projecting signal. By adopting the embodiment of the invention, the operation flow of the user is simplified, and the safety of the projecting data is enhanced. The embodiment of the invention also discloses a device and system for applying the method.

Description

technical field [0001] The present invention relates to the field of data technology, in particular to a projection method, device and system. Background technique [0002] With the advent of the information age and the rapid development of multimedia technology, the application of projectors is becoming more and more extensive. More projectors currently used include ordinary projectors and network projectors. Wherein, when using ordinary projectors, the projector must be directly connected to a certain computer through a data cable supporting a VGA (Video Graphics Array, video image array) interface. On the computer, the location of the projector is restricted. At the same time, users need to operate and configure projection switching, which is inconvenient for users to operate and use, and the projection cannot be displayed in the case of hardware conflict or incompatibility, and the wear and aging of the VGA cable interface often make the projection display abnormal. ...
