Audio Alignment Level
The Audio Alignment radio buttons provide a means to select from EBU for standard
European transmissions or SMPTE, the standard for North American transmissions.
The ranges in dBm are shown below:
• EBU [0dBm = -18dBFS]
• SMPTE [+4dBm = -20dBFS]
Network Confi guration
IP Type
The Internet Protocol Type drop-down entry fi eld provides the choice of either Static or
DHCP [Dynamic Host Confi guration Protocol] to confi gure the NewStream transmitter.
Internet Protocol addresses are assigned to a host either at the time of booting, or
permanently, by fi xed confi guration of its hardware or software. Fixed, or persistent
confi guration uses a Static IP address.
DHCP is a network protocol used to confi gure network devices to communicate on an
IP network. A DHCP client uses DHCP protocol to acquire confi guration information,
such as an IP address, a default router and one or more DNS server addresses from
a DHCP server. The DHCP client then uses this information to confi gure its host. Once
the confi guration process is complete, the host is able to communicate on the Internet.
IP Address
The Internet Protocol Address that is displayed for the
NewStream transmitter can
be modifi ed. Click within the fi eld and type the value of the address that you want to
modify. Click Save Changes to retain the IP Address. When NewStream uses the
DHCP type, this fi eld displays the IP address received by the DHCP server.
Net Mask
A sub-network, or subnet, is a logical subdivision of an IP Network. All computers that
belong to a subnet are addressed with a common, identical, most-signifi cant bit-group
in their IP address. This results in the logical division of an IP address into two fi elds: a
network or routing prefi x and the rest fi eld or host identifi er. The rest fi eld is an identifi er
for a specifi c host or network interface. Special gateways called routers exchange
traffi c between sub-networks. Such routers constitute the logical or physical boundaries
between the subnets.
To change the Net Mask address, type the new value and click Save to retain the
Subnet Mask. When
NewStream uses the DHCP type, this fi eld displays the Subnet
Mask received by the DHCP server.
