Helix Broadcaster 100 Touch Screen User Guide CHAPTER 2: Inputs

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.
