These settings adjust the streaming mode, parameters and tables.
Own Name
You can enter the name of the Annuncicom IC here. This name will be returned when using the DISCOVER command (see technical documentation)
Default setting is "".
Streaming mode
"send always" will stream always
"send on TALK" will stream if the TALK button (command) is pressed
"send on Level" will stream if the incoming audio signal is above the Trigger level
"auto answer" will stream back for the Post Trigger Play duration after a stream has been received
"receive only" can receive a stream but will never send one
Default setting is "send on TALK".
Trigger level
Is only used when Streaming mode is "on Level".
Set to a value between 0 and 32767.
Open the Device status page and look for the Input peak value to get a hint for the trigger value. This page refreshes itself every second.
Default setting is "1000".
Pre Trigger Start
Pre Trigger Start can be adjusted to prevent cut offs when audio should be sent earlier than detected. It defines the duration of the stream used before the actual trigger occurred.
This feature is normally used in combination with the send on level feature.
However, this parameter has a further use, to determine the receive stream strategy.
If 0, a minimum audio delay strategy is chosen at the receive side. Otherwise a minimum audio loss strategy is chosen.
Default setting is "0" milliseconds.
Post Trigger Play
Post Trigger Play can be adjusted to prevent cut offs when audio should be sent longer than detected. It defines the amount of time that the device will continue streaming after the actual trigger has been cleared. This feature is normaly used with the send on level feature.
When Streaming mode is set to "auto answer" this defines the duration the device will stream back after a stream has been received.
Default setting is "0" milliseconds.
Buffer Underrun Mode (TCP)
The Buffer Underrun Mode (TCP) defines the action if a TCP stream is slower than the real stream from the encoder. In this case the output streaming buffer underruns and cannot hold older data anymore. The device can then "disconnect" the TCP connection or it can "skip" the stream directly to the encoder stream without disconnecting TCP.
Default setting is "disconnect".
Background Stream TCP Flow Control
The Background Stream TCP Flow Control defines data receiving strategy of stream interrupted by a priority stream (so called background stream). If a priority stream is played, data in original stream can be either accepted and thrown away or the TCP connection can be stopped.
Use throw away data if your streaming source is streaming in real time (e.g. Annuncicom). Use stop stream when the streaming source is sending data as fast as possible (e.g. when sending a file from a PC).
This setting is only for receiving data and does not affect UDP streams.
Streaming Strategy
The Streaming Strategy defines how a packet is built and sent. On "lowest latency" the encoded data will be sent directly after the encoding. On "optimal package" the packet will be filled up before sending.
Default setting is "lowest latency".
Non MP3 Packet Size
The Non MP3 Packet Size defines with how many bytes a non MP3 packet will be filled up before it is sent.
Set to a value between 1 and 1200.
Default setting is "1200".
Play Buffer
Defines the amount of bytes that will be stored before playing the received stream. Lower this value to minimize delay, increase this value to prevent dropouts.
Default setting is "4096" Bytes.
Receive Timeout
Defines the amount of time between the end of a received stream and switching to being able to send.
Default setting is "200" msec.
TCP Priority Rx Port
Enter the port number for receiving a priority TCP stream. This stream always takes precedence.
Set to a value between 0 (disabled) and 65535.
Default port is "0".
UDP Priority Rx Port
Enter the port number for receiving a priority UDP stream. This stream always takes precedence.
Set to a value between 0 (disabled) and 65535.
Default port is "0".
Priority Message Minimum Volume
This is the guaranteed minimum volume for the priority message (received through UDP or TCP Priority Streaming Listen Port). If the current volume is less than this and priority message begins, the volume is set to this volume and reset back to original value when the message ends.
Default: "25%".
UDP Receiver Port
Enter the port number for receiving a UDP stream.
Set to a value between 0 (disabled) and 65535.
Default port for UDP is "3030".
UDP Tx Source Port
This setting is only used when working with a custom software application. Enter the source port number to be used when sending a UDP stream. Set to a value between 0 and 65535. When set to 0 the port defined in the Stream table destination entry is taken. Or if Stream destination is set to "origin source" then the UDP Receiver Port is used.
Default setting is "0".
Radio Path
Enter a radio path to listen to the transmitted stream of this Barix Annuncicom IC using a device that is able to play MP3 radio stations (also PC software like WinAmp).
The URL to connect is http://x.x.x.x/p. Where x.x.x.x is the IP address of this device and /p is this Radio path.
Example: http://192.168.0.24/xstream
The device can serve up to 6 radio streams.
Default setting is "/xstream".
Relay While Audio
Activate relay when sound is coming out of the analog output and deactivate when not. Default setting is "OFF".
Stream
Choose if the stream should be sent to the defined entries in the table or to the last calling station (to the device where the last communication came from).
Table
The numbered links will allow you to configure several tables which can be selected over the command interface during operation.
Trap Target IP Address
Enter the IP address of the SNMP trap destination.
Default setting is "0.0.0.0".
Low Audio Level
Define the low audio level for the trap generation. A trap will be generated as soon as the audio level goes below this value (and the silence timeout is run out).
Default setting is "0".
High Audio Level
Define the high audio level for the trap generation. A trap will be generated as soon as the audio level goes above this value.
Default setting is "0".
Trap Repeat
Define the repeat interval for the SNMP trap sending. The trap will be repeated if the values are still according to the defined trap stages after this repeat time.
Default setting is "0".
Silence Timeout
Define the time that has to run out before a trap is sent when the audio level is below the defined low audio value.
Default setting is "0".
