This is a sink element. It is used to generate SRT (Secure Reliable Transport) streams. This is a modern IP streaming protocol that offers higher reliability and security than conventional transport options.
| ! | SRT Caller Mode and Listener Mode |
|
SRT offers different modes to establish a connection between peers. In aixtream, caller mode and listener mode are supported.
|
| L | SRT parameters |
| This article references SRT parameters. More details on these can be found here. |
| E | Cautious configuration recommended |
| The SRT sink element includes many options that require an in-depth understanding of IP technology and network routing to configure properly. This is especially true of the Expert view options. Caution is advised when configuring these options. For most applications it is enough to set the desired Port and Host and leave the other options untouched. |
| Element | Description |
|---|---|
| Port |
Sets the target port to stream to. “7001” is the default SRT target port. |
| Host |
Sets the target IP to stream to. If this field is left empty, the SRT sink operates in listener mode. |
| Network interface | Dropdown: Selects the network interface to stream from. |
| Local Port | Sets the local port to stream from. |
| Passphrase |
Sets the passphrase to decrypt the stream. If this field is left empty, no encryption is used. |
| Latency | Sets additional latency to the stream in miliseconds. This may be used to ensure compatibility with some remote systems. |
| Bandwidth limit |
Sets the maximum bandwidth usage in kilobytes per second. Corresponds to the SRT parameter maxbw. |
| MTU size |
Sets the Maximum Transmission Unit size in bytes. This is the maximal size for a data unit that may be sent. Corresponds to the SRT parameter mss. |
| Payload size |
Sets the size of the payload in bytes. Corresponds to the SRT parameter payloadsize. |
| Bandwidth overhead |
Sets the overhead in percentage. The higher the percentage, the more reliable the connection will be, but the more bandwidth is required. Corresponds to the SRT parameter oheadbw. |
| Receiver buffer size |
Sets the buffer size in bytes on the receiver side. A higher buffer increases transmission quality but increases output delay. Corresponds to the SRT parameter rcvbuf. |
| Sender buffer size |
Sets the buffer size in bytes on the sender side. A higher buffer increases transmission quality but increases output delay. Corresponds to the SRT parameter sndbuf. |
| Statistics interval | Sets the time in seconds after which current SRT statistics are retrieved. |
| Payload | |
| Payload dropdown |
Dropdown: Selects the payload muxing.
|
| Call profile | Dropdown: Sets the Call Profile to use for this connection. |
| NTP header extension (RFC 6051) |
Toggles NTP header extension “On” or “Off”. See RFC 6051 for details. |
