A Location-free Commentary Adding System for Live Streaming Using a Cloud Infrastructure

摘要

In this paper, we present a commentary adding system for http-based live streaming that can add audio of running commentaries to existing streaming video from any place using only internet access and a PC. We also propose the use cases of this simple commentary adding system for live streaming and explain how to implement additional audio in synchronization with the original stream. This system enables the location-free, internet-based remote production of running commentaries and also shows promise to be used in OTT services that are spreading rapidly in recent years.
