The Digital Living Network Alliance (DLNA) recently announced that guidelines for version 4.0 of its technical standard for streaming digital content in the home via smart TVs, set-top boxes (STBs), PCs and mobile devices is available for download.
DLNA 4.0 establishes a blueprint that can be used by manufacturers, supply chain partners, distributors and retailers to assure that their customers’ connected equipment, devices and services are interoperable and adhere to industry-accepted quality standards, DLNA highlights in a press release.
“DLNA 4.0 is designed to raise the bar for enjoyment, energy efficiency and a seamless viewing experience across many different types of consumer products in the connected home,” DLNA VP of technology and strategy Duncan Bees was quoted as saying.
“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.”
DLNA 4.0 addresses the issue of interoperability across home network servers, smart TVs, PCs, STBs PCs and mobile devices by requiring that media servers incorporate transcoding.
In addition, DLNA 4.0 supports the High Efficiency Video Codec (HEVC) video compression standard and IPv6, thereby ensuring home networks continue to perform as the transition to the new IP standard continues.
Higher energy efficiency is another of DLNA 4.0’s touted benefits. Built-in low power modes boost energy efficiency, and hence reduce electricity consumption and costs, of certified DLNA 4.0 home network equipment and devices.
More than 4 billion connected devices have been certified under DLNA 2.0 and 3.0. DLNA 4.0’s backwards compatibility assures earlier devices will continue to operate in a DLNA 4.0 home network environment.
