Abstract

Digital cinema is a promising application that utilizes high-speed optical networks to transfer super high definition (SHD) images. The networks are primarily used for distributing digital cinema contents in packet data form, and are also used to support new services such as the live streaming of musicals and sport games to movie theaters. While current transfer services offer high-definition (HD) quality video, live-streaming applications will soon shift to providing cinema quality 8K content to both business and movie theaters users. The extra- high-quality 8K format enables a realistic telepresence, and will be combined with special tools such as video editing systems to realize effective remote collaboration

To explore the application range of 8K video beyond digital cinema, we developed a JPEG2000based 8K real time streaming codec system. This codec can compress/ decompress 8K videos: the total bit rate exceeds 12 Gb/s (4 : 2 : 2, 60 frames/s), and the resulting 5001000-Mb/s compressed streams are transferred as IP packets. While digital cinema em- ploys the 24-frames/s movie format to replicate the cinema style, it is believed that at least 60 frames/s is needed for realistic video

8K Format
8K is a new resolution standard designed for digital cinema and computer graphics.
It has following advantages:
1. Higher image definition quality.
2. More detailed picture.
3. Better fast-action.
4. Larger projection surface visibility.

8K format was named because it has 4000 pixels horizontal resolution approximately. Meanwhile, standard 1080p and 720p resolutions were named because of its vertical resolution. The new standard renders more than four times higher image definition than 1080p resolutions for example. This format can’t have
