• DVTS is an application for sending and receiving DV streams (~30 Mbps)

sender

07/16/08 intERLab 10

Problem in fore-said scenario

• Multicasting is not enabled in many network then

Unicast (one receiver) is only choice

• IPv4 / IPv6 mismatching

• Limited Number of receiving points

DVRelay: Systematic Approach

DVRelay Installations1. Linux Kernel Source

– apt-get install linux-source– cd /usr/src – tar -xjf linux-source-2.6.22.tar.bz2

2. Create Symbolic Links– cd /usr/include– sudo ln –s

/usr/src/linux-source-2.6.22/drivers/ieee1394/dv1394.h

– sudo ln –s /usr/src/linux-source-2.6.22/drivers/ieee1394/ieee1394-ioctl.h

DVRelay Installations3. Libraw1394

– tar -xvzf libraw1394-1.2.0.tar.gz– ./configure– make– make install– make dev

DVRelay Installations4. DVRelay

– tar -xvzf dvrelay0.1f.tar.gz– cd dvrelay0.1.f– ./configure– make– make install

DVRelay Installations• List of parameters• root@dvr~:# dvrelay –H

-v : show version number-6 : use IPv6 (Default)-h hostname : send to host "hostname"-4 : use IPv4-f rate : send full frame by 1/rate-j group : join mulitcast group "group" example, [-j 239.100.100.100]-M ifname : multicast join interface "ifname" example, [-M fxp0]

DVRelay Installations-t ttl : TTL for multicast-T : write RTP seq num in trace file'Relay_RTP_Seq_Trace.txt'

-C : use CBR Q for forwarding packets-P port : RTP port number "port" example, [-P 7990]-s number : number of DIF blocks included in one packet-L : show packet loss-R : don't use RTCP-N : do NOT send video-l number : show packet loss, specify display granularity-H : show this help message-p : use PAL

DVRelay Operation• -f rate : Send reduced picture frame DV

rate of 1/"rate".

Example:

dvrelay -h 202.28.6.9 -f 2 (Half rate video)

• -t ttl : TTL for multicast packets.(default value is 1).

Example:

dvrelay -h 239.100.100.100 -M fxp0 -t 20
