Premium VOD Presentation APOWG Update Civolution Watermarking and De-Coding March 3, 2011 Content Protection Intelligence Center PRIVILEGED AND CONFIDENTIAL

Civolution VOD Watermarking • NexGuard-PayTV watermarking technology also used in post-production and digital cinemas • Watermarks imperceptible to consumers • Watermark payload embedded either locally by STBs or prior to delivery by VOD servers – Includes Operator ID (Satellite/Cable provider, ISP), User ID (consumer ID), and Date/Time • Millions of devices already deployed and ready to be activated with software push 2 PRIVILEGED AND CONFIDENTIAL

Civolution VOD Recovery Process 1. ID the Operator • Studio downloads pirate content and uses Civolution’s Packer to ‘compress’ file for testing – Packer completely spoils video making it unwatchable (removes color, resolution, etc.) but retains payload – Reduces testing sample size to ~15-20MB • Studio uploads sample to Civolution detection portal • Automated detection returns Ticket #, Operator ID, and Date/Time 3 PRIVILEGED AND CONFIDENTIAL

Civolution VOD Recovery Process 2. ID the Consumer • Studio (or CP vendor) sends Ticket # to Operator • Operator references Ticket # to Civolution detection portal • Automated detection returns User ID to Operator 4 PRIVILEGED AND CONFIDENTIAL
