The WHDI (Wireless Home Digital Interface) consortium this week announced technical features that will be included in upcoming versions of the WHDI specification. WHDI will release a WHDI 3D spec update with support for all stereo-3D formats required by the latest HDMI version by the end of 2010. In addition, the WHDI 2.0 spec will include support for ultra high-definition (UHD) formats.
The WHDI group will release WHDI 3D specification update that will document WHDI support for all 3D formats required by the HDMI 1.4a specification in Q4 2010. Following the 3D update, the next version of the WHDI standard, WHDI 2.0 that is set to be available in Q2 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 (4096 x 2160 pixels);
- WHDI-Wi-Fi integration and same channel co-existence;
- Mobile device integration through reduced power consumption and footprint.
It is unclear when actual products supporting WHDI 3D- or WHDI 2.0-compliant products are set to become available.
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, providing superior security and digital content protection.
WHDI is the dominant wireless video standard in the market. A recent industry report from West Technology Research Solutions (WTRS), a wireless industry analyst, 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 sharply 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.
