Abstract: Embodiments of a system and method for low-latency content streaming are described. In various embodiments, multiple data fragments may be sequentially generated. Each data fragment may represent a distinct portion of media content generated from a live content source. Each data fragment may include multiple sub-portions. Furthermore, for each data fragment, generating that fragment may include sequentially generating each sub-portion of that fragment. Embodiments may include, responsive to receiving a request for a particular data fragment from a client during the generation of a particular sub-portion of that particular data fragment, providing the particular sub-portion to the client subsequent to that particular sub-portion being generated and prior to the generation of that particular data fragment being completed in order to reduce playback latency at the client relative to the live content source.

Abstract: In various implementations, a server is configured to execute instructions stored in storage that when executed perform operations that include receiving a hypertext transfer protocol (HTTP) request to stream a video segment of multimedia content to a client device. The video segment is of a video sub-stream of the multimedia content. The operations further include sending the video segment and an audio segment to the client device based on the HTTP request for the video segment. The sending pushes the video segment and/or the audio segment to the client device. The audio segment is of an audio sub-stream of the multimedia content. A plurality of segment sets may be pushed based on the HTTP request for the video segment. Each segment set can include an additional video segment and an additional audio segment that correspond to at least partially concurrent portions of the multimedia content.
