Abstract:
Techniques for preventing circumvention of digital rights management protections on electronic content are provided. A method according to these techniques includes receiving a content stream, obtaining samples from the content stream, generating a histogram based on the samples from the content stream, classifying the content stream as including audio content or non-audio content based on the histogram, and modifying portions of the content stream responsive to classifying the content stream as including non-audio content. The content stream can be modified such that any video content included in the content stream would be rendered unplayable, while audio content included in the content stream remains playable.
