What does 'Delivered', 'Opened' and 'Video Views' represent?

The results screen shows for each recipient of the email, what they did with it. 
'Delivered' means that AutoPlay's email server was successfully able to send the email to the customers email address. 
'Opened' means that the recipient opened the email in their inbox (if images are downloaded), or in the web page. 
'Video Views' represents the number of AutoPlay Virtual Demos the recipient watched. 
Note - these are all currently tracked in iOS and the old Silverlight Studio, but have been renamed here for improved clarity.
