Emerging Applications • Ultragrid • iHDTV • CineGrid 4k
Emerging Applications • Ultragrid: 1920x1080 compressed video, 8kHz 2 channel audio (64Kbps), 250 Mbps – 1.5 Gbps
• iHDTV: 1920x1080 uncompressed video, 24bit/48kHz 2(+) channel audio, 1.5 Gbps
• CineGrid 4k: 4096×2160 JPEG 2000 video, 24bit/48kHz 16 channel audio, 6 Gbps
Ultragrid •
Laboratory of Advanced Networking Technologies at Masaryk University in Brno, Czech Republic
Ultragrid Bandwidth usage: 250 Mbps – 1.5 Gbps
Ultragrid • Video: 1920 x 1080 (1080i), full or reduced color space, uncompressed or compressed
• Audio: Uses RAT “Robust Audio Tool”, 8kHz, G.711 compression, max 64 Kbps
• Latency: Low when uncompressed (~80ms), higher when compression used
iHDTV Bandwidth usage: 1.5 Gbps
iHDTV • ResearchChannel along with the University of Washington
iHDTV • Video: 1920 x 1080 (1080i), full color space, uncompressed
• Audio: 24bit/48kHz 2(+) channel audio • Latency: Low (~80ms)
iHDTV • 2 PCs per endpoint: Xeon or Core 2 Duo • 2 gigabit ethernet cards per PC • Capture: Blackmagic Decklink Extreme PCIe
• Decode: AJA Xena HS
iHDTV
iHDTV
• 1080i video camera with component or SDI output
• Component -> HDSDI converter (as necessary)
• AES audio encoder • HDSDI audio embedder • HDSDI audio disembedder • HDSDI -> component converter (as necessary)
iHDTV
• Cost per endpoint: ~$10,000 USD
