The Digital Living Network Alliance (DLNA™) is a consortium of companies from the Personal Computing, Consumer Electronics and Mobile industries.

The organization's mission is to promote interoperability of products in the digital home. There are more than 220 member companies spanning more than 20 countries.

 

LNI and the DLNA™ CTT

LNI has worked extensively with DLNA™ for the past four years to develop and promote the DLNA™ Certification and Logo program. LNI’s conformance test tools are the only tools used around the world by DLNA™ Certification Labs to verify compliance to the DLNA™ Guidelines, DLNA™ Enhanced Guidelines and DLNA™ Link Protection Guidelines.

Service Offerings

LNI is available for the purpose of streamlining DLNA™ product development. The Conformance Test Tool (CTT) includes thousands of tests to ensure compliance with the DLNA™ guidelines. Product development and resolving compliance failures is time consuming and expensive for DLNA™ companies. LNI offers specification knowledge and familiarity with the test tools to work with clients to best prepare devices for certification and upcoming Plugfests.

Link Protection Technologies

With more are more premium digital media flowing from content providers directly to end user’s home PC’s and entertainment systems, a need has emerged to protect that content from theft during transit.  Digital media is most vulnerable to theft during electronic transport – easy to use software is freely available on the internet which gives the user the capability to copy and reconstruct files from network traffic.  However, premium digital media is not the only target for data theft.  Personal emails, documents, and other sensitive data could be stolen from your home network by simply viewing the network traffic.   On the forefront of the initiative to secure home network links are the technologies of DTCP-IP and WMDRM-ND.

DTCP - IP:

Digital Transmission Copy Protection for Internet Protocol. This technology is a relatively simple, but extremely powerful system to authenticate and share data between devices.  It uses uniquely signed device certificates for authentication, and AES-128 Data Encryption to protect transmitted data.  The technology is content agnostic, which means that it can be used as a “pipe” to deliver any data the user wishes, and be assured that the data was secure during transport.

WMDRM - ND:

Windows Media Digital Rights Management for Networked Devices.  This technology also implements Device Certificates, and AES-128 Data Encryption, but takes Link Protection one step further and implements Digital Rights Management.  This allows content providers to issue licenses along with delivered content which specify usage rights.  Unlike DTCP-IP however, this technology is currently only suited for digital media.

 

LNI and Link Protection

The DLNA™ Link Protection Test Tool (LPTT) is a complete test suite developed for the certification and development of DLNA™ Media Devices which implement Link Layer Protection.
