GANZ Network camerab and encoder series
RTSP configuration for MULTICAST
NOTE : If you have decided the communication way between multicast and unicast, the option
is applied to both of first stream and second stream on the web page. BUT, each of the 1
nd
stream and 2 stream can be configured with different way by HTTP API. Refer to the NVC
HTTP API manual.pdf in the SDK.
IP Address
In order to get the streaming data from GANZ ENCODER AND NETWORK CAMERA, you should
set the IP address of group which is used for PC to join. '0,0,0,0' is configured as a factory
default and it enables router program to generate the available IP for GANZ ENCODER AND
NETWORK CAMERA automatically. If you want to use any specific address, type the address in
the blank.
NOTE : UDP/RTP multicast is not allowed for streaming even if the address and the port
information is known.
How auto configuration of IP address works?
As the session name for each RTP session is defined already on the server, your PC can get the
stream by the 'rtsp:// rtsp server ipaddress : port / rtp session name' without the manual
decision of IP address on the webpage.
Port
Set the port number used for router to receive the streaming data from GANZ ENCODER AND
NETWORK CAMERA (No need for unicast). '18888' is set for video data of 1st stream and
'28888' is for video data of 2nd stream. Refer to the 'Ports list for GANZ ENCODER AND
NETWORK CAMERA connection' at the end of this section4.5.6.
TTL
Set the TTL value. If you set 1 for TTL, it means the packet will pass only in a subnet (No need
for unicast).
What is TTL?
It's the abbreviation of Time to live. If data is sent out from GANZ encoder via network and
all of the packets are alive permanently on the network, it will cause the big network load.
TTL helps to reduce the network load by controlling the time of staying on network. For
example, if you set the TTL as 50, the data will be deleted after passing by 50 routers.
Packet Size
Select the packet size you want. You should consider the proper packet size according to your
network bandwidth. If your network allows you enough bandwidth for GANZ ENCODER AND
NETWORK CAMERA connection, you can set higher size. The factory default is 1500 bytes.
Session name
Type the session name. The allowed range for the session name is 64 characters with
alphabets, Arabic numbers, and under bar(_).
Session information
Type the session information you want to display.
