Systems and methods for high availability HTTP streaming

摘要

According to some embodiments, systems, methods, apparatus, and computer program code are provided to process video source data to generate a high availability segmented video stream for delivery to client devices. Pursuant to some embodiments, the video source data is packaged into a first segmented video stream and a second segmented video stream, and a first stream manifest file for the first segmented video stream and a second stream manifest file for the second segmented video stream are generated. A high availability stream manifest file is generated based on the first stream manifest file, the second stream manifest file and information associated with the availability of individual segments of the first and second segmented video streams. The segmented video stream data is then provided via the high availability stream manifest file to one or more client devices over one or more network connections.

主权项

1. A method comprising:
receiving, at a processing system, video source data; packaging the video source data into a first segmented video stream and a second segmented video stream; generating a first stream manifest file for the first segmented video stream and a second stream manifest file for the second segmented video stream; identifying one of the first and second segmented video streams as the currently active one of the streams, wherein the currently active stream is the stream currently being received by a user; generating a high availability stream manifest file based on the first stream manifest file, the second stream manifest file and information associated with the availability of individual segments of the first and second segmented video streams; and providing the high availability stream manifest file to a client device over a network connection.
