In this chapter you will learn how to add, connect to, edit and remove Channels in the just:in user interface.

What is a Channel?

A Channel is a virtual representation of a single input of your Video Capture Device. Depending on the number of Capture Devices and the number of inputs each device offers, you may configure one or multiple Channels.

Adding a Channel

1. Open just:in.
2. Open the Connections Window by selecting the menu command Channel → Connections or use the shortcut command + K.
   
3. In the lower area enter the IP Address and the Port of the desired Channel. Press the Add button afterwards.
   
4. The Channel will be added to the Channel List. The actual Channel Name shown in this screenshot is only available once the Channel has been connected to. Before connecting to a Channel a question mark will be shown.
   
5. You may now connect to the Channel by following the steps below.

Using the Port-Autocounter when Adding Channels

When adding multiple Channels they usually have consecutive Port numbers (50000, 50001, 50002 and so on). The just:in Connections Window automatically increases the Port number after adding a Channel to the Channels list.

Connecting to a Channel

1. Open just:in.
2. Optional: if there are multiple Channel Views, first select the View you want to connect to the Channel. You can still reorder Views later by drag & drop, as described in the chapter Managing Views.
   
3. Open the Connections Window by selecting the menu command Channel → Connections or use the shortcut command + K. You can also click on the Connections Window button while hovering above a Channel View.
   
   
4. Press the Connect button of the desired Channel to connect to it.
   
5. The Channel Preview should now be shown and you are ready to use the Channel.
   
6. If you should get this warning, double check your IP-Address and Port as well as the configuration of just:in Engine and the network. Also read the troubleshooting info at the end of this chapter.
   

Disconnecting from a Channel

1. Open just:in.
2. Optional: if there are multiple Channel Views, first select the View you want the Channel to be disconnected from. 
3. Select the menu command Channel → Disconnect or use the shortcut command + shift + D.
   
4. You may now connect another Channel to the View.

Removing a Channel

1. Open just:in.
2. Open the Connections Window by selecting the menu command Channel → Connections or use the shortcut command + K.
   
3. Click on the X button of the appropriate Channel to remove it from the Channel Manager. This cannot be undone.

Pending Channel Connections

When a Channel connection cannot yet be established or has been interrupted, the Connections Window will display Connecting… on the particular Channels. Wait for the Channels to be online or read the troubleshooting information below.

Troubleshooting

Connecting to a Channel may not immediately work when just:in Engine is not properly configured or reachable. There may be other reasons, the most common ones are listed here.

• Wrong IP Address and/or Port: consult your administrator for further information. If you have configured the network by yourself, verify if everything is set up correctly.
• just:in Engine not running and/or Channels not activated in just:in Engine: verify that just:in Engine has been started and that the desired Channels are activated. Also verify that the particular Channels you want to connect to are not occupied by another just:in client.
  
• just:in Engine not reachable: verify if the network connection has been set up properly.
• Unstable Video Preview and/or connection losses: there may be network connection issues. Use a stable and fast network connection between the just:in user interface and just:in Engine. Do not use a WiFi connection.
