Overview

The following is an explanation the general concepts of the Render Streaming system.

System Structure

The Render Streaming system consists of the following 3 components

• Unity (Editor or Application)
• Web server
• Web browser

In Render Streaming a P2P network is created between Unity and the Web browser, and this network sends data via UDP/IP. The Web server enables communication between the Web browser and Unity. This communication is called signaling.

Warning

Currently does not support the following features.

• Streaming video from the browser to Unity
• Streaming audio from the browser to Unity

The Signaling Process

The following is an explanation of how signaling works.

1. Web browser sends Offer SDP to the Web server.
2. Unity checks the Web server for unprocessed Offer SDPs and receives any found.
3. Unity sends Answer SDP to the Web server.
4. Web browser checks the Web server for unprocessed Answer SDPs and receives any found.
5. Web browser sends ICE Candidate to the Web server.
6. Unity checks the Web server for unprocessed ICE Candidates and receives any found.
7. Unity sends ICE Candidateto the Web server.
8. Web browser checks the Web server for unprocessed ICE Candidate and receives any found.

Package Structure

The Render Steraming package includes the following.

• WebRTC package
• Sample code / assets
• Web application

WebRTC Package

This provides the WebRTC C# API. See the WebRTC package documentation for details on the API.

Sample Code / Assets

This is a template project containing an HDRP template sample which also incorporates Render Streaming.

Web Application

Includes a client side and server side sample. Also provides the signaling server features. For details, see the documentation. For information on signaling protocols, see Documentation.
