Expand the Receivers (RX) (A) portion of the AoIP menu, revealing the ADD/DEL buttons (B). Clicking ADD generates a new stream with the default settings and name. Clicking DEL deletes the selected individual stream. Each Receiver (C) has its own configuration and status page.

Protocol (D)

Selects the type of AoIP stream. Choices include Livewire, AES67, and ST2110.

Status (E)

  • Session Status - Displays the status of the current session.

  • RTP Status - Displays the status of the Real-time Transport Protocol.

  • Provisional Stream Status - Displays live status information for the stream.

  • Interface 1 and Interface 2 - Displays the RTP status of the individual interfaces.

Note - The fields displayed will vary depending upon which protocol is selected. For example, AES67 and ST2110 will show SDP information, which is not applicable to Livewire. AES67 is shown in Figure 1.

Settings (F)

  • Enable - Enables or disables the stream.

  • Stream Name - Allows for a unique name for the stream.

  • Channel Count - Displays the number of enabled audio channels present in the stream.

  • Seamless Protection Switching - When enabled, specifies the reconstruction of the original stream in case packets are lost in any path per SMPTE 2022-7.

  • SDP - Allows the Session Description Protocol information to be entered (AES67 and ST2110 only). SDP information will be gathered and displayed in the Discovery section and may be copied and pasted here.

Note - For senders that do not support NMOS, you may use the Ravenna2SAP tool available at

The parameters below are available when Show Expert Settings is enabled:

  • Codec - Selects the desired codec (AES67 and ST2110 only).

  • Auto Link Offset - Enables or disables auto link offset.

  • Link Offset - When Auto Link Offset is disabled, allows a specific link offset value to be added to the minimum RTP offset to keep the RTP offset value positive.

  • Ignore RTP Payload Type - When enabled, the RTP payload type will be ignored.

  • RTP Port - Specifies the RTP port.

  • Interface 1 and Interface 2 - Enter the multicast destination address of the receiver in the Destination IP Address field. When the Livewire protocol has been selected, an additional field for the Livewire Channel number appears.

Discovery (G)

The Discovery section shows the senders available via Livewire, AES67, and ST2110. When highlighted, the details of each stream will be displayed. A Filter field provides a means of entering a stream name or keyword to minimize the amount of scrolling required on a large network. Clicking the Apply button will copy the announcement information to the current receiver.
