Menu: Decoder / Source

DEC-3

00™ is capable to receive a stream either as a unicast stream or a multicast stream. According

to the entered source IP-address, the decoder will automatically recognize whether it concerns about
a unicast or multicast stream.

Figure 11

shows the ‘Decoder / Source’ page of the DEC-300™ decoder.

Figure 11: 'Decoder / Source' page of the DEC-3

00™ decoder

Table 10

describes the ‘Decoder / Source’ page of the DEC-300™.

Settings:

Description:

Transport Protocol:

Specifies  the  transport  protocol.  You  can  choose  between  the
connectionless  protocol  UDP  and  the  connection-oriented
protocol TCP. If you use TCP, your source must also support the
TCP protocol. Furthermore, no multicast is supported when using
TCP.  If  you  choose  ‘TCP/SERVER’,  your  source  must  be  the
client.  If  you  choose  ‘TCP/CLIENT’,  your  source  must  be  the
server. For more information, please see chapter 4.3 on page 47.

.!.

If network errors occur in your network, we

recommend using TCP protocol.

IP address:

Specifies the stream which should the DEC-3

00™ receive.

If you want to receive a multicast stream:
Please enter in the ‘IP address’ field your desired multicast IP-
address, e. g. 239.252.20.100.
If you want to receive a unicast stream:
Please enter in the ‘IP address’ field the IP-address of the source,
e. g. the IP-address of the ENC-3

00™, see Figure 12.

Or type in ‘0.0.0.0’

Port number:

Specifies the port number of the stream which should DEC-3

00™

receive. Enter here the port number of your desired stream.
