DiiVA Consortium Announces Mobile Extensions to the DiiVA Specification

New Features to Unify Wired Video & Data Interface Architectures for CE and Mobile Devices

GUANGZHOU, China — Mobile World Congress 2012 — The Digital Interactive Interface for Video & Audio™ (DiiVA™) Consortium today announced the release of the DiiVA 1.1a specification which adds provisions for a standard low pin-count mobile interface targeted at portable devices such as tablets, smartphones, digital cameras and camcorders.

Current efforts to connect mobile devices to consumer electronics such as television are either video-centric or data-centric interfaces. DiiVA is the first interface which unifies simultaneous transmission of full high-definition video, audio, data for file transfer and charging power in a single low pin-count connector. DiiVA enables space-constrained mobile devices to maximize functionality over a single connector.

“Enabling DiiVA on mobile devices opens the door for new usage models and applications that can marry uncompressed video, data traffic and charging without having to switch cables.” said Steve Yum, president of DiiVA Licensing LLC. “The DiiVA Promoters are offering a technology that will cost-effectively encapsulate multiple protocols and works with the current DiiVA interface standard. The end result is a standard that seamlessly bridges all the ways a mobile device needs to connect to a CE network through a single cable.”

With products based on the DiiVA 1.1a specification, end users will be able to use their mobile devices as both a control point over their home network and as a source of content. DiiVA-enabled mobile devices will be able to simultaneously send 1080p uncompressed video, copy files, receive charging power and launch apps on other devices. Application developers can take advantage of the DiiVA standard to change the way users interact with content–making access to content more natural and allowing users to get to their content faster.

The original DiiVA interface architecture uses four twisted pairs inside the DiiVA cable. Three of the twisted pairs are dedicated to sending uncompressed video at 4.5Gbps per pair. The fourth twisted pair is a half-duplex, bi-directional data channel is capable of simultaneously sending multiple protocols such as high-definition video, audio, USB, Ethernet, commands and content protection.

The mobile extension of the DiiVA specification is a two twisted pair architecture using one twisted pair for video capable of handling full high-definition 1080P at 60 frames per second and one twisted pair for data that is the same as the original DiiVA specification. Under the DiiVA interface all DiiVA products (mobile and non-mobile) will be interoperable with each other. In addition, the micro-DiiVA receptacle is compatible with micro-USB plugs so devices employing DiiVA can be multi-purposed for both USB and DiiVA functionality. Mobile devices equipped with the micro-DiiVA receptacle will be able to receive charging power from either a DiiVA display or a USB host.

“The DiiVA Mobile Extensions will be an important addition to the Chinese CE ecosystem,” said Secretary General of the China Video Industry Association (CVIA), Ms. Weimin Bai. “By using DiiVA technology Chinese manufacturers will be poised to play a large role in the global trend towards convergence of mobile devices with the home entertainment network.”

The first public demonstration of DiiVA 1.1a technology for mobile devices is planned for the Mobile World Congress in February 2012.
