Control Panel
Explains key concepts and operation of the cloud-based Control Panel.
The cloud-based Control Panel is designed for remote management of multiple locations of publishers and receivers. Operation is similar to that of VT Publisher and VT Receiver: it is possible to publish feeds, set up a stream between locations, and grab the Web Preview link.
The Control Panel works both with VT Publisher and VT Receiver, but is also capable of working with the UI-less version – VT Server. Although, we do not recommend you to simultaneously run VT Publisher and VT Server on the same machine.
The Control Panel requires a VT license to operate. If you don't have a license, simply follow the signup instructions. Once you've signed up, you can always download your license from the Control Panel.
First, make sure that you have instances of VT Publisher, VT Receiver or VT Server running under your current license.
Go to the VT Control Panel and enter the email and password that you received with your license. Click "Sign in".
The Control Panel will load.
The UI will display all VT instances that are currently running under the same license.

Publishing streams

The "All" panel shows all sources that are available at this location. If you want to transport a source, you must first publish it. To do so, hit "Publish":
Confirm by hitting "Start publishing". With this, the source will move to the "Sources" panel, where you can control it.
Select the stream from the "Sources" panel and hit "Stream to".
Control
Function
Destination
Destination of the stream – this is the location to stream to.
Output name
Select from the available output options (the Control Panel knows what output options are available on the selected receiving side). You can select options: Custom - this is the NDI output option, and you can assign a custom name for the output feed List of the devices - select the device where you want to output your stream
Bitrate
Choose the max bitrate of the stream
Latency
Select the Latency buffer size. More detailed information is available in the VT Receiver documentation.
Configure the settings and click "Stream".
Now, the stream with the specified name is on the "Out" panel on the publishing location and in the "In" on the receiving location.
Stream starting example
A source can be sent to any number of receiving locations. All streams are sent with the SRT-HEVC encoding option.

Configuring transport parameters

Protocol and bitrate can be changed dynamically for each of the active streams:
  • To change the protocol, select it in the control available for the stream in the "In" panel.
  • To change the bitrate, select the new option in the control available for the stream in the "Out" panel.
Bitrate can be changed dynamically for each of the active streams. Just click on the bitrate drop-down list of the stream and select the desired value.
Also, you can select the value called Custom and enter the desired value (counts in Megabits per second)
Example of bitrate setting

Stream monitoring

In the Control Panel, you can preview your stream on the encoder (1 on the picture below) location and on the decoder(2 on the picture below) location.
Two types of preview
On the next picture, you see the Sources section preview thumbnail.

Stream security settings

This menu is summoned by clicking the Key symbol over the Sources section preview thumbnail. Allows you to alter stream security settings. Actually, it is a web counterpart of the Security Settings in VT Publisher. All of the changes that you've made here will be reflected in the apps and vice versa.
Here is how it looks by default:
Stream security settings
The "Allow anonymous access" switch is on by default and you need to switch it off to restrict the stream access to designated accounts.
Let's create a security account.
Click on the "Add" button to create new login credentials to access the stream.
Account add process
The system will automatically suggest the name of the account and generate a random password. You can change it as you will. Then you need to set the start and expiration time. If you will not set a Start time account will be active till the Expiration time. If you will not set Expiration time account will have perpetual access.
Active switch is supposed to enable or disable the account.
The account you've created will appear in the list.
