Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
LG Electronics, Matsushita Electric (Panasonic), NEC, Samsung, Sibeam, Sony and Toshiba have formed a special interest group to develop wireless technology to enable high-definition audio video (A/V) streaming and high-speed content transmission between consumer electronics devices.
They are developing a wireless high-definition digital interface (WirelessHD or WiHD) (www.wirelesshd.org) that they hoped wil be adopted throughout the industry, and expect to have this completed by Spring 2007. The group intends to promote the rapid adoption, standardisation and multi-vendor interoperability of WirelessHD technology worldwide.
"WirelessHD will provide a high-speed wireless digital interface that will enable customers to simply connect, play, transmit and port their HD content in a secure manner," said John Marshall, chairman of WirelessHD.
As iTWire noted just last week, service providers are presently opting for either broadband over powerline of proprietary high speed variants of WiFi to overcome the need to run wires around a home to deliver video services from the point of entry to the preferred viewing location. However the WirelessHD technology is designed more to replace the short range cable technology used to connect devices together. According to Brian O'Rourke, a senior analyst with In-Stat/MDR, "WirelessHD will provide consumers wireless flexibility and ease of use while preserving the benefits traditionally associated with popular wired alternatives for point-to-point display, such as HDMI and DVI."
Justifying the move, WirelessHD notes that "The migration to high-definition content along with the proliferation of digital source devices has intensified consumers' desire to simply and flexibly connect to highest quality, high-definition displays and consumer electronics systems." In-Stat notes that global sales of devices with a high-speed digital A/V interface is expected to grow from 60 million units in 2006 to 495 million units in 2009.
WirelessHD will operate in what the group says is the unlicensed, (class licensed in Australia) globally available 60GHz frequency band and is expected to be built into HDTV's as well as a wide range of audio video (A/V) devices, both fixed location and portable. It is being billed as the first and only wireless digital interface to combine uncompressed high-definition video, multi-channel audio, intelligent format and control data, and Hollywood approved content protection.
The first generation of the technology is data rates from 2Gbps to 5Gbps for the CE, PC, and portable device segments. However its core technology is claimed to support theoretical data rates as high as 20Gbps, permitting it to scale to higher resolutions, colour depth, and range. The WirelessHD platform is designed to operate cooperatively with existing, wireline display technologies. No indication has so far been given as to the range over which it will operate, or the number of devices a single system wil support.
