SYNOPSIS

dvsend [ -v64NLH ] [ -h hostname ] [ -f rate ] [ -M ifname ] [ -t ttl ] [ -I 1394if ] [ -P port ] [ -s number ] [ -d port ]

DESCRIPTION

dvsend is part of the DVTS(Digital Video Transport System). dsend receives DV/IEEE1394 packets and sends DV/RTP packets.

OPTIONS

The options are as follows:
-v Show version number of dsend
-6 Use IPv6 for sending DV/RTP packets. (default)
-4 Use IPv4 for sending DV/RTP packets.
-L Show the packet loss state at the receivers. Packet loss information at the receivers are sent to the dvsend using RTCP. By using this option, the packet loss information gained from the RTCP RR messages are displayed.
-H Show the help message.
-h hostname
  Send DV/RTP packets to "hostname".
Example) dvsend -h ff02::1
dvsend -h 10.0.0.10
dvsend -h dest.domain.mydomain
-f rate Send reduced picture frame DV/RTP stream. The DV/RTP stream will be sent by the rate of 1/"rate".
Example) dvsend -h dest.domain.mydomain -f 2
(Half rate video)
-M ifname
  Use interface "ifname" for sending multicast packets.
Example) dvsend -h 239.100.100.100 -M fxp0
-t ttl TTL for multicast packets. (default value is 1). Example) dvsend -h 239.100.100.100 -M fxp0 -t 20
-I 1394if
  Use device "1394if" for IEEE1394 output. (default value is "ohci0").
Example) dvrecv -I ohci0
-P port Use port for sending DV/RTP packets. (default value is 8000).
Example) dvsend -P 8100
-s number
  Pack multiple DV DIF blocks in one DV/RTP packet. DV data consists of multiple 80 byte long DIF blocks. Using large "-s number" will decrease number of DV/RTP packets, and decrease routing table lookup cost at the routers. (default value is 17).
Example) dvsend -h dest.domain.mydomain -s 17
-d port Send DV audio data using different UDP port. (default disabled). Example) dvsend -h dest.domain.mydomain -d 8030
