Thank-you for contacting Slingbox Forum. Slingbox can be connected to cable boxes and other audio visual devices.
Here is a link to help you see the hook-up possibilities. Some cables come with the Slingbox. Some you may need to get.
At this link, you will need to pick the specific Slingbox you may have and follow the product to the hook-up and set-up of the Slingbox options.
Hope this helps with your issue!
Have a great day!
