DLNA 4.0, the latest Guidelines from The Digital Living Network Alliance for streaming personal content in the home, provide support for HEVC video compression, opening the way for Ultra HD distribution. They also mandate transcoding on the media server, ensuring all files on server devices can be played on mobile devices, PCs, TVs, set-top boxes or other devices, so overcoming a long-standing complaint from consumers that not all files were accessible.
The new 4.0 Guidelines also support IPv6 to ensure DLNA 4.0 Certified devices will continue to function as more networks transition to this protocol. Power efficiency is improved through low power modes that enable connected devices to work together to cut overall energy consumption in the home.
The DLNA 4.0 Guidelines can be downloaded here.
They have been submitted for adoption as an international standard by the IEC, which has published all previous sets of DLNA Guidelines for content sharing applications and protected streaming across home networks. The DLNA 4.0 Certification Program will join existing DLNA 2.0 and 3.0 Certification Programs, the organisation reports.
“DLNA 4.0 is designed to raise the bar for enjoyment, energy efficiency and a seamless viewing experience across any different types of consumer products in the connected home,” says Duncan Bees, Vice President of Technology and Strategy at DLNA. “With the new Guidelines and logo, consumers will be able to buy products that they know will work together to the highest levels of compatibility while supporting the latest high-definition media formats and energy-saving features.”
