To toggle between two scope variables within a view when one is not defined

In my application, I am utilizing two scope variables: $scope.banner and $scope.defaultBanner.

The banner is fetched using a service, but in cases where the banner file does not exist, the variable will be empty as the service returns nothing.

My goal is to display the defaultBanner if $scope.banner is undefined. However, the priority is always to show the banner from the service if available.

Is there a way to achieve this?

UPDATE

I am specifically looking for an angular solution or any technique that can be implemented directly within the HTML view.
