Abstract
There are some researches in transmission of high definition image using Internet Protocol (IP) before. Materials for TV stations require lossless transmission by uncompressed real-time transmission. Also high performance camera and display require transmission methods for 4K2K (3,840 x 2,160 pixels) image over HD (High Definition; 1,920 x 1,080 pixels). Especially, projection to huge screen such planetarium requires at least 4K2K resolution. However, uncompressed transmission of both HD and 4K2K require such high bandwidth network as 1.6 Gbit/s and 6.4 Gbit/s, then we prepared dedicated networks such SONET or wide-area VLAN service. Therefore we spent a lot of procedures and costs.
在利用互联网协议(IP)传输高清图像方面,已有一些研究。电视台的资料要求通过不压缩的实时传输进行无损传输。此外,高性能相机和显示器需要传输方式4K2K (3840 x 2160像素)的高清图像(高清晰度;1,920 x 1,080像素)。特别是,像天文馆这样的大屏幕投影至少需要4K2K的分辨率。然而,高清和4K2K的非压缩传输都需要1.6 Gbit/s和6.4 Gbit/s的高带宽网络,因此我们准备了SONET或广域VLAN业务等专用网络。因此我们花了很多程序和费用。
