Video Stream Proxy Replication for Synchronous Screen Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video projection technologies face issues of network pressure and power consumption in VR terminals due to the need for simultaneous video streaming, leading to projection freezes and reduced quality.
Innovation Solution
A proxy server is introduced to replicate and forward video streams between VR terminals, reducing the need for direct streaming and minimizing network pressure and power consumption by synchronizing video playback across terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the VR terminal sends the video stream to the set-top box for projection, then projection functionality is achieved, but network pressure and power consumption of the VR terminal increase excessively
Solution Approach 1:
A proxy server is introduced as an intermediary between the VR terminal and the set-top box. The proxy server receives the video stream from the VR terminal and forwards it to the set-top box, reducing the network pressure and power consumption of the VR terminal while maintaining projection functionality.
2Ease of operation
If the VR terminal sends the video stream to the set-top box for projection, then projection functionality is achieved, but network pressure of the VR terminal increases excessively causing video freeze
Solution Approach 1:
The proxy server acts as a mediator that buffers and manages the video stream transmission. It receives the video stream from the VR terminal and forwards it to the set-top box, preventing network congestion and video freeze while maintaining smooth projection functionality.
3Ease of operation
If the VR terminal sends the video stream to the set-top box for projection, then projection functionality is achieved, but network pressure of the VR terminal increases excessively
Solution Approach 1:
The proxy server is positioned between the VR terminal and the set-top box to manage network traffic. It receives the video stream from the VR terminal and forwards it to the set-top box, significantly reducing the network pressure on the VR terminal while maintaining projection functionality.

AI summary
The present invention discloses a video projection method and apparatus, a computer device, and a storage medium, and relates to the field of video technologies. The method includes: receiving, by a proxy server, a projection proxy request message from a second terminal, where the projection proxy request message carries at least stream information of a first video stream that is being played by a first terminal; and performing matching on a data stream sent by a video server to the first terminal from a received video stream; when finding the first video stream, replicating the first video stream; and sending a video stream obtained through replication to the second terminal. In the present invention, the proxy server finds the video stream that is being played by the first terminal from the received video stream, and sends the video stream corresponding to a video that is being played by the first terminal to the second terminal, so that the first terminal and the second terminal perform synchronous playing. This prevents the first terminal from sending a video stream to the second terminal, reduces network pressure and power consumption of the first terminal, and avoids a video freeze, thereby improving projection quality.
