The following parameters are defined when you create a new audio device.

To make Lawo VSC easy to configure, most of the parameters are hidden from view and calculated for you from the audio device configuration.

The parameters can be viewed from HOME if HOME integration is configured.

The "Label", "Media Interface", "Protection" and "Max Receivable Channels" fields cannot be modified once a receiver is created.

LabelLink to Label

The Receiver Label identifies the receiver within the network. It cannot be left blank and cannot be edited once you have created the receiver.

The identifier string must not contain the character “/” (ASCII/UTF-8: 47) and must begin with a letter or the lower line character “a”-“z”, “A”-“Z”, “_” (ASCII/UTF-8: 65-90, 97-122 ,95).

Receiver labels must not exceed 28 characters.

Media Interface & ProtectionLink to Media Interface & Protection

These fields determine which interface, or interfaces, will be used to receive the connected stream from the network.

By default, all new receivers are configured to use two network ports in Dual Redundant mode so that they can accept two SMPTE ST2022-7 compatible streams (for redundant streaming). You can choose to receive these streams non-redundantly by choosing either Primary Only or Secondary Only.

If the connected stream's SDP is not SMPTE ST2022-7 compatible, then the "Protection" field is set to Primary Only (by default). In this instance, you can change the receiver port to Secondary Only if needed.

Max Receivable ChannelsLink to Max Receivable Channels

This value sets the maximum number of channels that can be received. Once an incoming stream is connected, if there is a mismatch, then the incoming channels are received on a best-effort basis. For example:

  • If a stereo stream is connected to an 8-channel receiver, then only the first two channels of the receiver are used.
  • If a 64-channel stream is connected to an 8-channel receiver, then channels 1 to 8 are assigned to the receiver and channels 9 to 64 are unused.

Syntonized vs Synchronized ModeLink to Syntonized vs Synchronized Mode

In the current release, Lawo VSC always operates in syntonized mode. 

Please note: If you view the Lawo VSC receiver parameters in the HOME UI, then you will see two options for Syntonized and Delay Relative to Source Timestamp. In the current release, these fields have no meaning for Lawo VSC.
