Update on Uncompressed HD Video over IP from GLORIAD-KR Sanggyun Kim GLORIAD-KR HDTV GROUP Sanggyun Kim on behalf of GLORIAD-KR HDTV GROUP
2 BW. RES. 1Mbps 10Mbps 100Mbps 500Mbps 1Gbps 50Mbps 352x288 H x x1080 MPEG2 MPEG4 H.263 MPEG1 DVD DV SD Uncompressed 1080i HD (995 Mbps, 1.3 Gbps, Gbps) Wireless/wired Laptop computer Access Grid IPTV Wired/Wireless Desktop computer HDTV Wired High-performance computer Uncompressed HDTV Multimedia over the Internet Powerful system Bandwidth guarantee Quality
3 Networked HDTV CompressedUncompressed Res.Up to 1920x1080 Bandwidth19.2Mbps1.485Gbps CODECMPEG2- Performance Handle one stream with high performance server (Single CPU) Handle one stream with high performance server (Dual CPUs) Delay En/ Decoding 1~2 seconds0 Buffering dependent on policy Ideally, 0~5 frames (0ms~166ms) Advantage - Low cost - Low bandwidth consumption - high quality -Low delay - Ultra-high quality Disadvantage -High delay - sensitive to packet losses - not fit into interactive applications -High cost -Large bandwidth consumption Killer apps. IPTVBroadcasting
4 One-way delay vs., user perception Will not notice the delay Will not need echo cancellation round-trip-time/2 delay (including Encoding/decoding delay) Recommended upper E2E delay limit May Based on PingER history. ping from the east Asia to the world Domestic (Korea) East Asia North America Russia Europe Middle East Latin America The delay is obvious to all users Will notice slight hesitation Etc. 100ms20ms150ms 200ms 300ms
5 Advantage of networked uncompressed HDTV over Broadcasting-style and its use Advantage - Extremely low processing delay (no codec) - ultra-high presentation quality (no spatial/temporal dependency) - easy access to the application technology - interactivity (1:1, 1:N, small group N:N) Use - Broadcasting industry HD distribution, visualization, authoring, and so forth - Digital cinema (combining with JPEG2000) reduce distribution cost, enhance presentation quality

7 GLORIAD-KR version of UltraGrid 1. Cost-effective system integration and development - Adopt low-cost HD-SDI Interface (AJA’s OEM_HS) - Add internal 24-bit 48KHz HW audio to the system : audio capture, separate audio RTP stream, audio playout - Support dual-port streaming with software packet-striping - SW-based multi-channel audio playout (PC sound card) 2. System Specification - Linux (Mandrake, Suse, Fedora Core 5) - EM64T dual Xeon (at least 2 PCI-X) - Dual-port 1 Gbps or 10 Gbps network interface

12 Partners 5 Sites are using GLORIAD-KR version of UltraGrid in the Globe
Grand Opening for Big GLORIAD(’05.9.5) The first round-the-world high-performance networks jointly established by Korea, China, Unite States, Russia, Canada and Netherlands Improve networked collaboration with e-Science and Grid applications like HEP, Astronomy, Fusion, Geosciences, Medical sciences, and so forth. Global Ring Network for Advanced applications Development (GLORIAD)
14 Demonstrations and Experiments with GLORIAD-KR Version iGrid 2005, Interactive 3D HD Video Transport and Collaborative Data Analysis for e-Science over UCLP. KISTI, GIST C-K Experiments, First C-K Uncompressed HD experiment exploiting GLORIAD network.
