AWS Elemental MediaLive improves input switching for live channels
You can now use the AWS Elemental MediaLive schedule feature to prepare a MediaLive channel input prior to switching to it. In the context of live video streaming, this functionality is also known as an ‘input cue’. Preparation of an input in advance of a switch helps reduce the latency of the scheduled switch action. For example, you may need to switch to an input for a postgame press conference that could start at any time. If the MediaLive schedule feature is used to prepare the input, you can switch to it with only a few seconds of latency.
