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

 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
