- DSCP : audio DSCP (34: RTP AES67 / 46: RTP Ravenna)
- RefClk PTP traceable: This feature is useful when you want to connect a stream through Internet (e.g. with two PTP Masters (GPS) at each locations), it allows to make connections with devices locked to different traceable PTP Masters.
See also Ignore refclk GMID - accept source locked to any PTP master on the Session Sinks section below. - Channels :
Channel count : number of channels in the stream. The drop down menu allows to select specific channels if the number of channels is smaller than the selected module channel capability (limitation : channels must be contiguous)
The URL of the SDP of this session is : allows to save the Session Description into a file (useful for specific third party devices if manual SDP has to be provided).
Note : Devices in 2022-7 mode will produce a 2022-7 SDP, containing both interfaces session parameters.
If you load such SDP in a non-2022-7 device, only the session parameters from interface1 will be used.
SESSION SINKS
Configuration
- Create session button : create a new session sink
- IO : select the physical output (when applicable)
- Label : Sink name
- Source : drop down menu to select a source (both sap and bonjour advertised sources are listed).
Manual : allow to manually enter a SDP - Delay (samples) : playback delay.
0 is automatic delay (automatic delay works for Merging Technologies devices).
For non-Merging devices, if set to 0, the playout delay is calculated based on the SDP a=framecount value.
In any case, the frames must be time aligned; all devices must run an integer number frames from time zero (epoch). - Ignore refclk GMID - accept source locked to any PTP master : This feature is useful when you want to connect a stream through Internet (e.g. with two PTP Masters (GPS) at each locations), it allows to make connections with devices locked to different traceable PTP Masters.
See also RefClk PTP traceable on the Session Sources page. - Ignore refclk Domain - accept source locked from any PTP master : This feature is useful when you want to connect a stream through Internet, it allows to make connections with devices locked to different PTP domains.
- Relaxed check - accept source with lower channel count : allow to connect to a source that have less channels.
- Channels : Channel count : number of channels in the stream. The drop down menu allows to select specific channels if the number of channels is smaller than the selected module channel capability (limitation : channels must contiguous)
Note: Supported RTP ports : 1024 to 65535 (Multicast) / 32767 (Unicast)
