Javascript - Detect when user switches to another application

Question

I am working on a web application that plays videos. I need to detect when the user switches to another application so that I can pause the video.

Eg the browser is still open in the background but the user is now busy in Skype or some other app.

You should only detect that your app is losing focus that should be enough for you to pause the player.
