The evolution of digital media is moving quickly beyond the PC. Consumers throughout the world are moving to take their music with them wherever they go. As connected and non-connected audio and video devices become more prevalent, it becomes critical to enable new business models that take advantage of consumer demand. Content rights holders are quickly seeking proven, reliable methods to deliver their content securely beyond the PC. To secure the media content that is on consumer devices, Helix DRM for Devices enables chip and consumer electronic device manufacturers to include DRM on their consumer devices and to keep content secure beyond the PC. As part of Real strategic initiatives to deliver media anytime, anywhere, and on any device, the flexibility of Helix DRM means that content rights holders can determine the rules for which they want to deliver content to devices. It also means that device manufacturers can provide a complete DRM solution on their devices that will meet the needs of consumers.
How It Works
Helix DRM 10 for Devices works in two different ways-Primary Device and Secondary Device -thus giving content rights holders and device manufacturers maximum flexibility over their business models.
Primary Device Support
A Helix DRM 10 Primary Device is a network-connected device such as a PC, Set Top Box, Home Media Server, or Mobile Phone. The Primary Device can connect directly to the Internet, and has local storage. Helix DRM 10 Primary Device support requires both the Helix DRM 10 and the Helix DNA client to run natively on the consumer device. In the Helix DRM 10 Primary Device implementation, the consumer acquires the secure media file from a media server, and then attempts to play the encrypted file on their Helix DRM 10 Primary Device. Because a license key is required to decrypt the secure media file, the Helix DRM 10 client running on the Primary Device makes a license request and the Helix DRM 10 License Server generates a license with the license key and the associated business rules defined by the content owner.
Secondary Device Support
Helix DRM for Secondary Devices enables Consumer Electronics Manufacturers to enable Industry Supported, Standards Based, Industry Leading secure media experiences such as subscription & purchase business models on a wide range of consumer, mobile, and portable devices as well as connected home appliances.
A Secondary Device is a device that requires a connection to a Primary Device for the transfer of data and rules for that data.
There are two models for integration with Secondary Devices through our private Helix Device DRM Community:
Secure Memory Device - With the Secure Memory protocol, manufacturers implement device compatibility with stored secure content and enable the transfer of secure content to the device from an application with native Helix DRM 10 support, such as the RealPlayer 10. By enabling the Secure Memory protocol, CE manufacturers will be able to offer secure download services such as the RealPlayer 10 Music Store to their consumers.
Secure Streaming Device - With the Secure Steaming device protocol, device manufacturers allow secure content to be streamed to their devices over a home network. By enabling the Secure Streaming protocol, CE manufacturers can make their devices compatible with premium content services to help drive demand for their device technology.
RealNetworks does plan to enable Secure Streaming via Digital Transmission Copy Protection over Internet Protocol (DTCP-IP). CE manufacturers are encouraged to implement a DTCP-IP sink in anticipation of future releases of RealNetworks' products which include support for DTCP-IP.
