Distributed implementation design of full software real-time encoder applicable for super high definition video
Sei Naito, Shuichi Matsumoto · 2009
Super high definition video such as 4 K digital cinema is expected as the quite attractive video application. With regard to the video transmission, recent compression coding standards are applicable for 4 K digital cinema. However, the typical implementation approach of a commercial video encoder is based on hardware architecture. As the limitation of hardware base implementation, once the equipment has been completed, further improvement such as supporting higher resolution video or adding unsupported coding tools would be pretty difficult. On the other hand, distributed computing by utilizing several PC platforms has become more typical as the approach for developing a high performance computer system. With regard to the real time application where precise timing control is required, the practical example of distributed computing system has not been existing yet. From this perspective, this paper describes the key technology necessary to realize full software implementation of real time video encoder by utilizing distributed computing technology.
