Digital Cinema over optical network - Status of super HD development -

摘要

Digital Cinema is a promising application that utilizes high-speed optical networks to transfer super high definition images. The networks are primary used for distributing packet data of digital cinema contents, and are also used to support new services such as the live streaming of musicals and sports games to movie theaters. While current transfer services offer HD quality video, live streaming applications will soon shift to cinema quality 4K to both business and movie theaters users. The extra-high quality 4K enables a realistic tele-presence, and will be combined with special tools such as video editing systems to realize effective remote-collaboration for business workspaces. This paper introduces current research on super high definition image transmission and its application especially in digital cinema and relevant application fields.
