1 Super high-resolution video handling system and highly accurate video traffic monitoring technology - Demonstrations at SC NTT Laboratories. * This work is supported by the National Institute of Information and Communications Technology. 1
2 Overview of the demonstrations 1. Over 10-Gbps high-resolution video handling system Video editing work flow of broadcasting station on IP networks 2. PRESTA 10G: 10-Gbps high-resolution network monitoring platform Network measurement for stable transmission of high-quality video streams Integration of multi-layer network monitoring into perfsonar Virtual Network #1 PRESTA 10G Osaka Virtual Network #2 Demo booth Virtual Network #3 IP-Optical network Internet2 SCinet 2 GEMnet2 JGN2plus
3 1. Over 10-Gbps high-resolution video handling system overview Functions: Transferring, recording, playback, and transcoding in real time Video formats: Uncompressed SD/HD/4K/8K-resolution video, compressed HD Video editing Video shooting Media server IP network Media transcoder 3 Video shooting Video editing
4 Components of the video handling system Media server Media transcoder PC-cluster based ultra-high-speed video server Recording/delivery high-quality video stream in real-time through IP network Uncompressed/compressed HD, uncompressed 4K/8K video Also delivery the video as a video file instead of video Maximum video delivery capability: 25-Gbps Equivalent to capability of 16-uncompressed HD video Connecting between video network and IP networks Simultaneously converting two HD-SDI video signals to IP packets and vice versa with ultra-low latency Converting ultra-high resolution video, such as 4K video or SHV using multiple Media Gateways Compress or decompress HD video in real time Transferring high-quality video over various bandwidth IP networks by implementing Media transcoder between Media server and 4
5 2. PRESTA 10G: 10-Gbps high-resolution network monitoring platform Features: Supports 10-Gbps Ethernet LAN-PHY/WAN-PHY and OC-192c POS 10-Gbps wire-rate full-packet capture and generation capabilities 10-ns-order packet time-stamping using external timing source Hardware packet-filtering Highly-accurate streaming traffic playback libpcap compatible API library Existing monitoring tools tcpdump softflowd Libpcap userlibrary Highly accurate traffic measurement tools ps-hra QoSmon SAA PRESTA user library PRESTA 10G Platform 5
6 Application example of PRESTA10G In 10-Gb/s networks, the time resolution at microseconds is necessary especially for measuring the video stream of 1-Gb/s and higher. Disorder of image by packet drop (uncompressed HDTV transmitted by i-visto) Measurement result of bit-rate calculated every 100 milliseconds bit-rate (Mbps) 100 seconds 1.6-Gb/s Time Measurement result of bit-rate calculated every 500 microseconds 500 mill seconds 9.0-Gb/s bit-rate (Mbps) 6 Time
7 Integration of multi-layer network monitoring into perfsonar Layer-7: streaming application header analysis perfsonar with high-resolution extension Layer-3/4: non-sampling Netflow v9 flow-records Layer 2: real-time behavior of traffic bitrate, delays, and jitters in micro-second resolution SAA softflowd tcpdump QoSmon SAA ps-hra tcpdump ps-hra Stream traffic softflowd SAA QoSmon tcpdump ps-hra softflowd QoSmon 7
8 Demonstrations of video transferring on IP networks Tokyo Osaka Video shooting Uncompressed 4K Compressed/Unco mpressed HD Media transcoder Tablet PC HD-Video & transcoder Media server cluster 4K-Video 8 PRESTA 10G Highly accurate traffic monitoring PRESTA 10G
