Overview

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

System Structure

The Render Streaming system consists of the following 3 components.

  • Signaling server
  • Peer 1 (Sender)
  • Peer 2 (Receiver)

Render Streaming System Structure

In Render Streaming a P2P network is created between two peers, and this network sends video/audio/binary data. The Web server enables communication between two peers. This communication is called signaling.

The Signaling Process

The following is an explanation of how signaling works.

Render Streaming Sequence

  1. Peer 1 sends Offer SDP to Signaling Server.
  2. The Peer 2 checks the Signaling Server for unprocessed Offer SDPs and receives any found.
  3. The Peer 2 sends Answer SDP to the Signaling Server.
  4. The Peer 1 checks the Signaling Server for unprocessed Answer SDPs and receives any found.
  5. The Peer 1 sends ICE Candidate to the Signaling Server.
  6. The Peer 2 checks the Signaling Server for unprocessed ICE Candidates and receives any found.
  7. The Peer 2 sends ICE Candidateto the Signaling Server.
  8. The Peer 1 checks the Signaling Server for unprocessed ICE Candidate and receives any found.
  9. The connection establishment between peers are completed and Peer 1 can send streams to the Peer 2.
