D EPT. OF I NFO. & C OMM., GIST Networked Media Lab.  Q & A 13

D EPT. OF I NFO. & C OMM., GIST Networked Media Lab. Appendix  imCast Setup step  Works for MediaX Library Development  Media Delivery System  OOP 14

D EPT. OF I NFO. & C OMM., GIST Networked Media Lab. 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   Platform : Fedora Core 5  Download latest version uv  tar –xvzf uv june-2.tar.gz (option. x : extract, v : verbose, z : unzip, f : file) Configuration  Sender IP : ,  Cast IP : ,  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

D EPT. OF I NFO. & C OMM., GIST Networked Media Lab. imCast Setup step (cont.)  Jumbo Frame Ping test ping –M do –s 9000 (-s option means mtu size) ping –s 9000 –d –v –M do  routing table setting route add –host dev eth0 route add –host dev eth1 route add –host gw dev eth0 route add –host gw 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 and make run./uv ifstat -b  imCast Cast server (33)../stereocast-kisti2/ultragrid/bin sh./running-stereo.sh ifstat -b 16

D EPT. OF I NFO. & C OMM., GIST Networked Media Lab. 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 Download DeckLink-SDK zip Download DeckLink rc-i386.deb Extract file  sudo unzip DeckLink-SDK zip it will create Black magic DeckLink SDK zip  sudo dpkg –i DeckLink rc-i386.deb (dpkg : debian package) 17

D EPT. OF I NFO. & C OMM., GIST Networked Media Lab.  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

D EPT. OF I NFO. & C OMM., GIST Networked Media Lab.  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 19

D EPT. OF I NFO. & C OMM., GIST Networked Media Lab. OOP(Object Oriented Project)  OOP(Object Oriented Project)  programming paradigm that uses objects  Feature data abstraction encapsulation modularity polymorphism inheritance etc. 20

D EPT. OF I NFO. & C OMM., GIST Networked Media Lab. OOP(Object Oriented Project)  TCP/IP Network Programming  TCP Echo Client/Server  Thread Client/Server  UDP multicast 21 application TCPUDP ICMP, IGMP IP Socket interface

D EPT. OF I NFO. & C OMM., GIST Networked Media Lab. 22  TCPecho Client / Server
