Subscribing to Media Channels

In the Routing View, a blue square at the intersection of an Rx and a Tx channel indicates that is it possible to create a media route between those channels. A grey square indicates that it is not possible to create a route between those channels. This may be because of a mismatch in sample rate between the transmitter and receiver, or because a device cannot route to itself.

When you click a blue square at the cross-point between a transmit channel and a receive channel, a subscription will be created, and a green tick    will appear in the matrix cross point. You may initially see a grey hourglass icon    (usually very briefly) to indicate that the subscription is in progress.

If there is a problem with the subscription, either a warning   or an error icon    may appear. If many devices have been subscribed at the same time, a yellow pending    icon may appear temporarily. Hover the mouse over subscription icons to see a related tooltip (see Subscription Tooltips).

Note:  Subscriptions can also be created in the Device View. This is covered in the Device View section.

Note:  You cannot create new subscriptions to a locked device; however, existing subscriptions can be removed and replaced.

Subscribing to Multiple Media Channels at once

To subscribe multiple channels at the same time, hold down the Ctrl key and click the [-] symbol at the top left corner of the intersection between the two devices. All possible channels will be subscribed at the same time (see the figure in Expanding the Routing View).

Unsubscribing Media Channels

To unsubscribe a media channel, click on the cross-point containing a subscription. The subscription icon will be removed and revert to a plain blue square.

Subscription Status

The symbol displayed at the intersection of the Tx channel and the Rx channel in the Routing View provides information on the status of the subscription or connection, as follows:

	In progress	The subscription is in progress
	Subscribed	Connection is established and fully functional
	Warning	This may indicate that: The subscription is unresolved, possibly because the transmitting device is not visible on the network (for example, because it has been removed, or switched off); or: There is another connectivity issue in the physical network that is affecting a media signal
	Error	An error has occurred - for example, there is insufficient bandwidth to establish the subscription
	Pending	Device is part-way through setting up subscription. Most commonly seen when subscribing many channels at a time

Note:  The status of a subscription can change after it has been initially established, due to changes in the network or changes in other devices.

Additional icons are used for devices that support Media Encryption.
