Question about my TIME WARNER/SPECTRUM TV BOX

[pangaia]

I have TIME WARNER Cable for TV ONLY.
I never watch TV so I cancelled the account. They said Keep the "Box." Whatever that thing is called.
Today I get a bill that included $123 for "unreturned equipment." The BOX I assume.

I plan to watch NETFLIX (I get DVDs) and I also BOUGHT an indoor TV antenna that sometimes gets a local station. :&gt )))
Maybe in the future I will want to play streaming things on the TV screen. Youtube, Netflix, etc,. I don't know much about it.


Can I return 'the box' and buy something to replace it? Do I need something to replace it..?
This is what it says on the box.

Many thanks for any help...
