  1. The streamer uses a video capture device to collect the content of a live stream and uses Push SDK to ingest the stream to Alibaba Cloud points of presence (POPs).

  2. ApsaraVideo Live uses edge ingest to ingest the stream to a specific live center of ApsaraVideo Live. The ingested stream is accelerated by POPs, which ensures the stability of the upstream transmission.

  3. ApsaraVideo Live ingests the steam from the live center to POPs.

  4. The viewers use ApsaraVideo Player SDK to watch the ingested stream.
