What Is Live?
HUAWEI CLOUD Live helps you smoothly deliver live streaming content to global audience with low latency.
In a typical live streaming event:
- A user uses a streaming tool to push a live stream to the Live center with uplink acceleration enabled.
- The Live center transcodes the live stream in real time as required.
- The processed live stream is distributed to viewers with downlink acceleration enabled.
- The Live service records the live stream to Object Storage Service (OBS).
