Input Interface
In the
Input Interface
drop-down, choose which Helix Broadcaster Ethernet connection receives
the stream. Typically this is the
WAN
port, which is the main IP address. If you have configured
the secondary Ethernet port using the browser interface (see page 7), you can choose the
LAN
address or
All
to monitor both the
WAN
address and the
LAN
address.
Note:
Typically you do
not
use the
Local Adapter
setting for network input. This
is the loopback address (
127.0.0.1
), which can be used only for a stream that
originates on the Helix Broadcaster machine.
Input Type (Unicast or Multicast)
For a UDP or RTP input, select
Unicast
or
Multicast
as the
Input Type
depending on the IP
address where the stream is directed. If you choose
Multicast
, the
Multicast IP
field appears. Tap
this field and use the virtual keyboard (see page 6) to enter the multicast address in the range
from
224.0.0.0
to
239.255.255.255
.
Note:
Receiving a multicast stream requires that Helix Broadcaster resides on a
multicast-enabled network.
Buffer Size
The input buffer size sets the number of milliseconds of input data that is buffered before it is
encoded. The default value is
300
milliseconds. For low-latency encoding and delivery, set a
value of
200
or
100
.
For More Information:
For details about low-latency encoding, refer to “Low-
Latency Encoding Values” on page 18.
Input Port
For a UDP or RTP stream, tap the
Input Port
field and use the virtual keyboard to set the Helix
Broadcaster port that receives the remote server stream. If the stream is multicasted, select the
port on the multicast address where the stream is sent. The remote server that initiates the
stream must be configured to send the stream to this port.
HTTP, RTSP, and RTMP Input
If you choose
http
,
rtsp
, or
rtmp
for
Input Protocol
, you specify the network address where Helix
Broadcaster acquires the stream.
