# previousChannelInterstitialViewController(for:)

Asks the delegate for a view controller that describes the layout of the previous channel’s interstitial view.

## Declaration

```swift
optional func previousChannelInterstitialViewController(for playerViewController: AVPlayerViewController) -> UIViewController
```

## Parameters

- `playerViewController`: The player view controller.

## Discussion

Discussion The framework calls this method when the user initiates, but hasn’t yet committed, a change in channel. The framework may call this method while a previous channel’s interstitial view is visible (on screen, or transitioning). important: Only live video streams support channel skipping. This feature isn’t supported for VOD streams or local media.
