It says consumers have long complained that there are files on their servers that they cannot play on their mobiles, PCs, TVs, set top boxes or other devices. DLNA 4.0 solves this problem by mandating transcoding on the media server.
“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,” said 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.”
Power efficiency is improved through low power modes that enable connected devices to work together to cut overall energy consumption in the home. Consumers also can now enjoy Ultra HD content streamed throughout the home via a media gateway or set top box because DLNA 4.0 supports the High Efficiency Video Codec (HEVC) video compression standard. The Guidelines also support IPv6 to ensure DLNA 4.0 Certified devices will continue to function as more networks transition to this protocol.
DLNA 4.0 Guidelines have been submitted for adoption as an international standard by the International Electrotechnical Commission (IEC), which has published all previous sets of DLNA Guidelines for content sharing applications and protected streaming across home networks.
