1. Analog Reconversion Problem presented by the Motion Picture Association of America to the Analog Reconversion Discussion Group February 12, 2003

2. 2 Analog Output (in the clear) Digital Video Recording Function Digital Video Recorder with Protected Digital Inputs Protected Digital Output (encrypted) Analog-to-Digital Video Converter Device Rendering Protected Digital Content with Usage Rights Information Digital Video Recorder with Analog Inputs Analog Reconversion Problem For legacy analog devices, protected digital video content must be converted to analog video signals.For legacy analog devices, protected digital video content must be converted to analog video signals. Analog video signals can be easily converted to digital without any obligations to preserve the content’s usage rights information.Analog video signals can be easily converted to digital without any obligations to preserve the content’s usage rights information. Since the usage rights are not managed equivalently, the natural transition from analog to an all-digital world is impeded.Since the usage rights are not managed equivalently, the natural transition from analog to an all-digital world is impeded. Rights are NOT managed equivalently Rights NOT Preserved Internet Rights Preserved

3. 3 Analog Reconversion Solution A standardized means for robust signaling of usage rights in analog video signals is needed to provide record control and redistribution control.A standardized means for robust signaling of usage rights in analog video signals is needed to provide record control and redistribution control. Detection of usage rights signaling must occur at the point of analog-to-digital video conversion.Detection of usage rights signaling must occur at the point of analog-to-digital video conversion. Upon this detection, the digital content must be protected with an approved digital output/connection/recording technology that preserves and enforces the usage rights.Upon this detection, the digital content must be protected with an approved digital output/connection/recording technology that preserves and enforces the usage rights. This technical means for preserving and enforcing usage rights needs to work for all devices capable of performing analog-to-digital video conversion.This technical means for preserving and enforcing usage rights needs to work for all devices capable of performing analog-to-digital video conversion.

5. 5 Proposed ARDG Work Plan Review past work and attempt to draw upon the conclusions and agreements reached from previous workReview past work and attempt to draw upon the conclusions and agreements reached from previous work Identify technical elements that require further investigationIdentify technical elements that require further investigation Investigate and discuss those technical elementsInvestigate and discuss those technical elements Co-chairs draft a Technical Report summarizing the work of the GroupCo-chairs draft a Technical Report summarizing the work of the Group

6. 6 Technical Elements requiring investigation 1) Rights signaling methods (e.g., CGMS-A, watermark, etc.) 2) Technical implications of prohibiting tampering with such methods
