Abstract
Techniques are disclosed for low latency live video streaming. A client can be configured to send a single HTTP request for live video streaming to a server. The server can be configured to push one or more video segments to the client in response to the request, following a pre-defined push strategy. For example, using a so-called all-push strategy, the client sends only one request to the server, and in response, the server sends all of the video segments to the client as soon as each segment is complete. The HTTP 2.0 protocol may be used for pushing the video from the server to the client. This technique eliminates the request explosion problem when small segments are used. Further, the number of segments pushed with each request can be varied, which is to facilitate adaptive bitrate switching.
