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
