Method of capture A delay at the source because of the capture workflow of the publisher’s environment. For example, a video publisher may have pre and post processing requirements which cause the stream to be delayed before being sent to the receiving endpoint. 2. Encoding It takes time for an encoder to receive the stream, process it, and output the new stream for delivery. Encoding can take place at the source of the capture or in the cloud, both cases will produce some delay. 3. Method of delivery A traditional CDN will need to cache live stream segments on a global network before they are able to be delivered to viewers over HTTP, this will generally add 30-60 seconds of latency to a live stream. Specialized network deployments are required to deliver sub-second latency streaming at scale.
