Newly launched DLNA CVP-2 guidelines remove the multiscreen device fragmentation roadblock

Last week, the DLNA announced the official publication of the new CVP-2 guidelines, which were developed by service providers in conjunction with some of the world’s largest CE manufacturers and technology suppliers including Comcast, Cox and Samsung. The aim of the new guidelines, which we discussed in January, is to enable operators to launch truly interoperable multiscreen services, responding to an increase in consumer demand for TV Everywhere. In light of the staggering number of DLNA certified products (336 million DLNA Certified smartphones expected to be sold in 2014 according to the DLNA), it is clear that the official launch of the guidelines comes at the right time. DLNA Certified Device growth is due to reach 7.32 billion by 2018, providing exciting opportunities for operators.

CVP-2 preserves content provider rights and ensures interoperability through protected streaming by leveraging DTCP-IP, which allows access to subscription TV throughout the home and across all enabled devices. This unique specification ensures that content can be shared securely between devices in a user’s home. However, it also ensures third parties outside of this network cannot access it. By providing ‘studio confident’ security, operators enable content owners and copyright holders to remain in control of the media sharing experience.

From a consumer perspective, it enables the seamless streaming of content to a multitude of compatible devices, allowing them to enjoy the full range of high quality content including HD programmes, movies, DVR content, channel guides, and other premium features on any screen in the home. Consumers now want the ability to watch premium content while moving from one room to the next, allowing technologies supporting HTML5 to come to the fore as they offer remote user interfaces that fit every screen. This enables operators to deliver a seamless experience across all screens, meaning that the user can start watching content on the living room screen and enjoy it as the consumer moves from one room to the next. The new guidelines, backed up by one of the most efficient standardisation organisations in the industry, empower operators by enabling them to deliver services that comply with both content providers’ and consumer demand.

CVP-2 provides many advantages for operators, which can be utilized to deploy multiscreen. These include:

– leveraging standardised technologies such as HTML Remote User Interfaces (RUI), HTTP adapted delivery and authentication to combine with current DTCP-IP Link Layer Protection
– ensuring that networked devices are green and conserve energy in line with power regulations and DLNA’s own voluntary initiatives. There is a built in mechanism for DLNA devices to display energy management functionalities for each of its network interfaces
–  catering for remote diagnostics and optimises the consumer viewing experience by including support for MPEG-DASH, an adaptive delivery technology for high-quality streaming which can deal with any bandwidth variation on the home network. It can support the adaptive delivery of content based on MPEG-2 TS and MP4 formats as well as for 3D video media format profiles and the modifications needed to allow the smooth insertion of advertisements.

ACCESS will demonstrate CVP-2 integration on the CableNET booth at the Cable Show in San Francisco (April 29th – May 1st).
