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
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
