Calculate bandwidth and data transfer requirements for video streaming.
Streaming bandwidth refers to the data transfer capacity needed to deliver video content to viewers in real-time. Both upload bandwidth (for broadcasters) and server bandwidth (for hosting platforms) are crucial considerations.
| Quality | Bitrate per Viewer | Use Case |
|---|---|---|
| 240p | 0.5 Mbps | |
| 360p | 1 Mbps | High-quality gaming, sports |
| 480p | 2.5 Mbps | Mobile devices, slow connections |
| 720p | 5 Mbps | HD streaming, most viewers |
| 1080p | 8 Mbps | Full HD, standard streaming |
| 1440p | 16 Mbps | |
| 4k | 35 Mbps |
Total Bandwidth Required:
Total Bandwidth = Bitrate per Stream × Number of Viewers
Example: 100 viewers watching 1080p (10 Mbps):
10 Mbps × 100 = 1,000 Mbps = 1 Gbps total bandwidth
Data Transfer Calculation:
Data Transfer (GB) = (Bandwidth in Mbps × Duration in seconds) / 8 / 1024
Important factors when planning streaming infrastructure:
Typical CDN and bandwidth costs:
| Monthly Transfer | Typical Cost Range | Use Case |
|---|---|---|
| 100 GB | $1-5 | Small podcast or blog |
| 1 TB | $10-50 | Medium streaming channel |
| 10 TB | $80-400 | Popular streaming service |
| 100 TB | $500-2,000 | Large-scale platform |
