SIGNAL & NETWORK
Bandwidth Calculator
Uncompressed and compressed AVoIP planning estimator.
Use this as a planning estimator only. Real multicast design also depends on codec choice, switch overhead, PTP/QoS, multicast control and vendor architecture.
AV-over-IP bandwidth estimator
Enter values and calculate.
AVIXA raw video data-rate estimate: R = H × V × bit depth × chroma factor × 1.25 × FPS × 3 color channels.
PCM audio = channels × sample rate × audio bit depth.
For compressed systems, use the selected product's documented maximum/worst-case bitrate whenever available. A generic compression ratio is only an estimate.
WORKED EXAMPLE
Example — 4K60 4:4:4 stream
The diagram shows the video parameters that drive bandwidth: resolution, frame rate, bit depth, chroma and stream count. Compression can reduce transport requirements significantly.
