A Distributed Video Processing System for Internet Live Broadcasting Services

Recently, Internet live broadcasting services such as USTREAM, TwitCasting, in which we, as broadcasters, can broadcast videos via the Internet have became popular. In Internet live broadcasting, broadcasters often add video effects to make live broadcasting exciting. However, the computational power of laptops for general users is not enough for complex video processing. So, Available effects are restricted in only simple effects. Moreover broadcasters cannot add video effects at their desirable timings. Although processing time can be reduced by using high processing power computers, they are expensive and difficult for users to get. Hence, in this paper, we propose a distributed video processing system for Internet live broadcasting services. Our proposed system equips high computational power servers owned by service providers. The devices of broadcasters send their recorded videos to one of the servers and the server broadcasts their processed videos to the clients. The broadcasters can add video effects while reducing the processing times for complex video effects. As a result of our evaluations, we confirmed that our proposed system can reduce the video processing time.
