Q: www network apple tv 4 gen

I'm sorry but I dont understand your question. If English is not your native language, you might want to post post I your native native language in one of the foreign language forums.

There are normally some hoops you can jump through as you create your iTunes account that workaround the need for a card, otherwise once the account is set up iTunes may still expect you to provide one, which you can subsequently remove. If you don't have or want to use a credit card at this time you can try this method using iTunes on a computer...

1. Enable the menu bar if needed with Ctrl+B (Applies to Windows only)
2. Sign out of the iTunes Store from the Store/Account item on the menu bar
3. Go to iTunes Store home page
4. Go to Quick Links > Redeem
5. Sign in with your Apple ID
6. Go through the screens, accepting the EULA, etc.  You should arrive at a Review Payment screen where one of the options is None - select this and continue. You shouldn't actually need to redeem a new voucher/card.

It is worth noting that one of the functions of the registration is to prove you have a valid billing address in the region whose store you are trying to use.
