-
Transcoding Servers:
- Connected to the Origin Servers.
- Convert raw video into various bitrates and formats compatible with HLS and MPEG-DASH.
-
Storage Servers:
- Linked to both Origin and Transcoding Servers.
- Store transcoded files, making them accessible for streaming via different protocols.
-
Load Balancer:
- Positioned between the Transcoding Servers and the CDN/Edge Servers.
- Manages traffic to ensure optimal performance and avoid overloads.
-
Edge Servers:
- Located closer to end-users in various global locations.
- Receive media content from the CDN and deliver it to user devices, ensuring faster, more reliable streaming.
-
Streaming Protocols (HLS & MPEG-DASH):
- Processed by the Transcoding Servers and distributed by both the CDN and Edge Servers.
-
User Devices:
- Positioned at the bottom.
- Represent a variety of devices (smartphones, tablets, TVs) accessing content via HLS and MPEG-DASH streams, with content often delivered by the nearest Edge Server.
