I have apple tv but cant stream live tv

How can I watch the mummers parade

On WFMZ.

• If you have an Apple TV box: WFMZ+ Streaming app - App Store preview - Apple (US) (The Apple TV app on smart TVs doesn’t bring an Apple TV App Store to those devices. You will have to choose from the app repository that the manufacturer offers.)
• The WFMZ app is also available on Roku, Fire TV, Android.
• WFMZ also streams through web browsers.

If your cable company provides an app that allows you access, you'll need to download that first. In addition, some major networks have apps that allow for streaming live.
