Included are techniques for selectively incorporating promotional messages into rendered video content, monitoring whether promotional messages are rendered or skipped, permitting payment for content upon rendering rather than receipt, controlling rendering of video to include or omit adult-themed sections, confirming a person'"'"'s age by reference to a watermarked identification document, and watermarking digital cinema projections.
