imCast Setup step

System operation environment Hardware Installation

2 video cameras should be connected with synchronizer Press the on/off button that will synchronize 2 Cameras 2 video cameras should be connected with 2 connector(AJA) 2 connector(AJA) have to be connected with each xena card

Software Installation Software Download & Install

http://good.kreonet.net/monet/doku.php?id=monet:uncompressed_hdtv:uchd Platform : Fedora Core 5 Download latest version uv-0.3.9.4 tar –xvzf uv-0.3.9.4-june-2.tar.gz (option. x : extract, v : verbose, z : unzip, f : file)

Configuration Sender IP : 210.125.84.18, 210.125.84.19 Cast IP : 210.125.84.33, 210.125.84.34 All files are located at /home/jcp ID : Root, Password : netmedia2848 imCast’s MTU must be set over 9000bytes, generally mtu is stetted 9180 bytes MTU Set : ifconfig eth0 MTU 9180

imCast Setup step (cont.)

Jumbo Frame Ping test• ping –M do –s 9000 <destip> (-s option means mtu size)• ping –s 9000 –d –v –M do <destip>

routing table setting• route add –host 210.125.84.18 dev eth0• route add –host 210.125.84.29 dev eth1• route add –host 210.125.84.29 gw 210.125.84.1 dev eth0• route add –host 210.125.84.33 gw 210.125.84.1 dev eth1

Operation KISTI Project

imCast Sender (18)• ../stereocast-sage/ultragrid/bin• sh ./running-stereo.sh• tip) if it doesn’t work properly (message : uv : symbol lookup error: ./uv:undefined

symbol : xenaGrabList2)• then ../stereocast-sage/ntv2linux-4.1.0 and make• run ./uv• ifstat -b

imCast Cast server (33)• ../stereocast-kisti2/ultragrid/bin• sh ./running-stereo.sh• ifstat -b

Works for MediaX Library Development

DeckLink Hardware Installation Input DeckLink Card to PCI express slot Connect Video camera and DeckLink Card with cable

DeckLink SDK Installation Go to http://www.blackmagic-design.com/support/software/ Download DeckLink-SDK-7.3.2.zip Download DeckLink-7.3.2.rc-i386.deb Extract file

sudo unzip DeckLink-SDK-7.3.2.zip• it will create Black magic DeckLink SDK 7.3.2.zip

sudo dpkg –i DeckLink-7.3.2.rc-i386.deb (dpkg : debian package)

17


Ubuntu version must be Ubuntu 9.04(called jaunty) or Ubuntu 9.10(called karmic). if you use Ubuntu 8.04(called hardy) or below version, it will

not make qformlayout.h so can not compile Some machine can not install Ubuntu 9.10 (Karmic)

if necessary, sudo apt-get update sudo apt-get install g++ sudo apt-get build-essential sudo apt-get dkms

sudo : super user do lib : library apt-get : ubuntu package installer

18


When play Displayer, it needs to be installed QT Libraries for QT install

sudo apt-get install libqt4-core sudo apt-get install libqt4-dev sudo apt-get install libqt4-dbg sudo apt-get install libqt4-gui sudo apt-get install qt4-designer sudo apt-get install qt4-dev-tools Write to .profile(./home/username)

PATH=$/usr/bin:$PATH
