Abstract: A live media processing and streaming service provides a content provider with media processing and distribution capabilities for live events. The service provides capabilities for capturing a live event, configuring programs from the live event, formatting the programs into a mezzanine format suitable for streaming, storage of the presentation manifest and fragments corresponding to a program into a cloud storage, and distribution of the presentation manifest and fragments to media consumers in real time.

Abstract: Audio tracks may be added to a live video stream using one or more mixers that may decode the audio from a video stream, mix an additional audio stream, and encode the mixed audio stream. The system may make the new audio stream available for live download by consumers. The mixers may include a video playback mechanism to view the live video stream, as well as an audio capture and mixing system that may create a new audio track that may be synchronized with the video stream using timestamps. A consumer device may download and consume the video with the new audio track on a slight delay from the live video stream.
