Abstract

Techniques for low latency streaming, for example in a broadcasting environment, are described herein. In some examples, a playlist may include both currently encoded segments, which are segments that are fully encoded at or before playlist generation, and also future encoded segments, which are segments that have not yet been fully encoded at playlist generation. In some cases, the inclusion of future encoded segments in a playlist may result in a player requesting a segment that has not yet been fully encoded at the time that the request is received by the server. In some examples, even though the segment is not yet fully encoded, the server may nevertheless save and process the request, for example by transmitting encoded portions of the requested segment as those portions are made available by the encoder.
