Abstract
Official abstract text for this publication.
A low latency streaming system provides a stateless protocol between a client and server with reduced latency. The server embeds incremental information in media fragments that eliminates the usage of a typical control channel. In addition, the server provides uniform media fragment responses to media fragment requests, thereby allowing existing Internet cache infrastructure to cache streaming media data. Each fragment has a distinguished Uniform Resource Locator (URL) that allows the fragment to be identified and cached by both Internet cache servers and the client's browser cache. The system reduces latency using various techniques, such as sending fragments that contain less than a full group of pictures (GOP), encoding media without dependencies on subsequent frames, and by allowing clients to request subsequent frames with only information about previous frames.
First claim
Opening claim text (preview).
We claim: 1. A computer-implemented method for receiving encoded media fragments from one or more encoders, the method comprising: sending encoder configuration information to one or more encoders that includes parameters to reduce latency for one or more clients watching a live event encoded by the one or more encoders; requesting a media manifest from each registered encoder that describes the media data available from the encoder; receiving an encoder manifest from each en…
