Skip protection requires the combination of QuickTime 5 or later client software and QuickTime Streaming Server 3.0 or later, or Darwin Streaming Server 3.0 or later software.
QuickTime 5 client software includes skip protection. To take advantage of skip protection, a QuickTime 5 client must connect to a server that is using QuickTime Streaming Server 3 or Darwin Streaming Server 3 software. The server must also be configured properly for skip protection.
QuickTime users can view content normally when these conditions are not met, but without skip protection.
