3D Coming to WHDI Wireless Specification

WHDI LLC announced the technical features that will be included in upcoming versions of the Wireless Home Digital Interface (WHDI) specification.

According to the statement, WHDI LLC plans release in Q4 2010 a WHDI 3D specification update that will document WHDI support for all 3D formats required by HDMI 1.4a. Following the 3D update, the next version of the WHDI specification (WHDI 2.0), targeted for release in Q2 of 2011, will include the following:

* Full 3D support (in addition to all HDMI 1.4a required 3D modes, WHDI will support the next generation 1080p 60Hzx2 3D format)

* Support for the next generation 2Kx4K HD format with four times the resolution of 1080p (4,096 x 2,160 pixels)

* WHDI-Wi-Fi integration and same channel co-existence

* Mobile device integration through reduced power consumption and footprint

A recent industry report from West Technology Research Solutions (WTRS) stated that WHDI technology will grow from nearly 70% of the 2010 market share for wireless video products to over 75% of the 2015 market. This contrasts with other technologies that could be used for wireless video such as WiDi, WirelessHD and WiGig, where WTRS projects marginal uptake in the wireless video market.

WHDI is a specification for the wireless distribution of HD (full 1080p/60Hz) video, enabling the ability to connect HD sources (STBs, Blu-ray players, PCs, mobile devices, game players, etc.) to TVs throughout and across the home. WHDI enables an HD wireless ecosystem for service providers, CE manufacturers and consumers. With WHDI, consumers can wirelessly connect all of their CE devices: WHDI delivers wireless PC and mobile phone to TV connectivity, and wireless whole home/multi-room DVRs and media centers.

The WHDI specification currently supports a high-quality, wireless link which can deliver uncompressed 1080p/60Hz in a 40MHz channel in the 5GHz unlicensed band, conforming to worldwide 5GHz spectrum regulations. Range is beyond 100 feet, through walls, and latency is less than one millisecond. WHDI supports HDCP revision 2.0 to provide security and digital content protection.
