Embodiment Construction

[0099] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0100] In the prior art, when performing multi-screen interaction, the display device needs to continuously send desktop image frames to the control device. The reception of the desktop image frame may be delayed, or there may be packet loss during the transmission of the desktop image frame, so that the control device may freeze when displaying the desktop image frame. For this reason, the present invention provides the following technical solution, when the display device displays the presentation, the demonstration image corresponding to each demo page in the presentation is sent to the control device; the control device displays the demonstration image, and receives the demo image the demonstration control operation; generate a dem...

Abstract

The invention discloses a multi-screen display method, device and system and belongs to the technical field of a computer. The method comprises the steps of generating a presentation image corresponding to each presentation page in a presentation file when a local presentation file is displayed; sending the presentation image corresponding to each presentation page to a control device; receiving apresentation control instruction sent by the control device; and displaying target presentation pages indicated by the presentation control instruction, and sending page identities of the target presentation pages to the control device, thereby enabling the control device to synchronously display the presentation images corresponding to the target presentation pages according to the page identities. According to the method provided by the invention, the problem that a delay phenomenon occurs when the control device displays desktop image frames is solved. When the control device displays thepresentation file on a display device, all presentation images corresponding to the presentation file are obtained, the data quantity transmitted from the display device to the control device is reduced, and transmission resources are saved.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular to a multi-screen display method, device and system. Background technique [0002] Multi-screen interaction refers to an interactive mode in which operations such as transmission, display, and control of the same multimedia content are performed between at least two devices. [0003] The related technology provides a multi-screen interactive method, the method includes: the control device and the display device adopt VNC (Viittual Network Computing, virtual network computer) technology to establish a remote desktop connection, and the display device uses RFB (Remote Frame Buffer, remote frame buffer) The protocol collects the desktop image frame used to display the desktop display content, and sends the desktop image frame directly to the control device; the control device receives the desktop image frame; since the desktop image frame has not been compre...
