Abstract

The embodiment of the invention discloses a screen projection method and apparatus. The screen projection method and apparatus are used for displaying display content on display equipment and a user terminal. The method provided by the embodiment of the invention comprises that: a gateway receives display content sent by a server, and the gateway sends the display content to a display device and auser terminal. The server only sends one piece of the display content to the gateway, and the gateway can send the display content to the display device and the user terminal without sending the display content to the display device and the user terminal respectively, so that synchronous display of the display content by the display terminal and the operation terminal can be realized under the condition that only one flow is consumed.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a screen projection method and device. Background technique [0002] Virtual reality VR terminals are personal wearable devices. Individuals can wear VR terminals to watch VR videos or play VR games. However, if you want to display VR content (such as videos or games) to others, you need to cast the VR content. Screen projection means that A device (such as a mobile phone, tablet or notebook) transfers the displayed pictures or images to B device (such as a monitor, digital TV or projector) through a wireless-fidelity (Wireless-fidelity, WiFi) network or wired connection. to display. Since VR content has the characteristics of strong interaction and real-time, high bandwidth requirements, high resolution, and high bit rate, the current projection of VR content on digital TV requires the cooperation between VR terminals, digital TV, and set-top boxes. accomplish. ...
