Abstract: Examples of the present invention provide a method of reducing the latency in streaming live media by a client from a server. The client uses manifest information to determine the “live edge” of the live media stream, where the live edge is represented by the segment from the media stream corresponding to the current time. The client then uses this to identify the next segment, which is the segment in time that will next become available. The client then starts making repeated polling requests for that next segment until the segment becomes available. As a result, the newest possible segment is obtained by the client as soon as it becomes available, and latency is reduced. Further, when adopted by all clients, the latency variation between clients is also reduced.

The operations can include streaming a media stream to a streaming client. While streaming the media stream, an outgoing queue of buffered streaming content to be sent to the streaming client can be monitored.

When a step up condition is satisfied, based at least in part on the monitoring, a switch can be made to a higher bit rate media stream for streaming to the streaming client. The operations are performed without receiving any quality feedback from the streaming client and without measuring bandwidth of the network channel.
