摘要：
In this paper, 4K & 2K multi-resolution and 60 fps progressive video transmission system is introduced. And its application to the world first bi-directional 4K and 60 fps communication experiments over IP network is discussed. This system implements JPEG 2000 multi-layer scalable coding technology and operates progressively with 60 fps. Its resolution is up to 4096 x 2160 pixels (called 4K), using layer structure concept combined with 2048 x 1080 pixels (2K) resolution. All digital video data are continuously transmitted at up to 700 Mbps over IP networks. This system opens the door to the next generation of CSCW (Computer Supported Collaborative Workspace) over broadband networks.
