With this week's Connected Home Global Summit 2011 in London serving as the backdrop, the Digital Living Network Alliance (DLNA) announced the release of new interoperability guidelines.

Developed in conjunction with global cable, satellite and telecommunications service providers, the new interoperability guidelines leverage DTCP-IP Protected Streaming to make service provider content more easily available for playback across digital televisions, Blu-ray disc players, game consoles and set-top boxes.

DLNA is a non-profit coalition of companies that are working together to make it easier for consumers to share content across their home networks and to various devices.

"Our service provider member companies have been instrumental in the development of these interoperability guidelines for playback of premium commercial video on DLNA-certified products," said Nidhish Parikh, chairman and president of DLNA. "Together, we are facilitating advances in the digital delivery of content to the home by building on the Alliance's rich set of technology to store and play content. The release of these interoperability guidelines is the first step in what is a key global strategic objective for DLNA over the next year."  

DLNA has worked with service providers on the delivery of digital content throughout the home since the Alliance's inception. DLNA interoperability guidelines are already in place as a component of the CableLabs tru2way home networking specification and associated open source reference implementation that enables secure transfer of cable content to DLNA-certified devices.

"CableLabs is pleased by the cross-industry effort spearheaded by DLNA to enable the delivery of commercial video to retail consumer electronics devices," said Paul Liao, president and CEO of CableLabs. "With these new DLNA interoperability guidelines, consumers soon will be able to purchase a DLNA-certified product that can access authorized content from any cable operator that provides a set-top box built to tru2way home networking specifications."

Late last year, CableLabs became a DLNA Promoter Member.

In March, CableLabs hosted an interoperability event based on the use of tru2way and DLNA for home networking. Another CableLabs interop, last year, demonstrated the sharing of premium DVR content among multiple tru2way set-top boxes and DLNA-certified devices.

"The new DLNA interoperability guidelines greatly assist Time Warner Cable by defining a common method to deliver our content to various retail consumer electronics devices such as connected televisions, game consoles, Blu-ray disc players, tablets and mobile phones – all securely using DTCP/IP link protection. Throughout our footprint, we continue to deploy more set-top boxes that are able to serve content to DLNA products certified to these interoperability guidelines," said Mike LaJoie, CTO of Time Warner Cable.

Product certifications for the new guidelines start later this year.

In addition to CableLabs, DLNA's Promoter Members include: Access, AT&T, AwoX, Broadcom, Cisco, Comcast, DirecTV, DTS, Dolby Laboratories, Ericsson, HP, Huawei, Intel, LG, Microsoft, Motorola, Nokia, Panasonic, Promise Technology, Qualcomm, Samsung, Sharp, Sony, Technicolor and Verizon.
