To the high definition wireless …

A new standard is on the horizon. Six giant electronics (LG, Matsushita best known for its Panasonic brand, NEC, Samsung, Sony, Toshiba) and a semiconductor manufacturer, SiBEAM, have formed an alliance to define the specifications of the Wireless HD. A technology that should enable to connect sources of High Definition (HD DVD players, Blu-ray players …) screens (LCD, plasma, projectors …), all wireless.

In itself nothing new, there are already wireless systems to transfer sound and image. But they compress the signal so that it can pass through the “pipes” available. The quality suffers. Currently, it is unthinkable to apply these techniques to HD and maintain quality. The Wireless HD proposes to use the radio frequency of 60 GHz to transmit 5 gigabits of data per second. This will have the same level of quality as HDMI and DVI connections. In comparison, the current wireless transmission technologies using frequencies ranging from 2.4 to 5 GHz, and therefore are more limited in the amount of data can be transmitted.

The scope of this new standard is limited to 9 meters. He clearly intended to make life easier for users, removing the headache that is now the proliferation of cables. The aesthetic is far from negligible, with the complete disappearance of these unsightly son. The specifications are still far from being arrested. The first version should be released in spring 2007 and should respect the digital content protection criteria. precondition for its adoption. The Wireless HD should not be confined to the home theater, and should also be found in laptops, camcorders …

The Wireless HD is however not alone. Other technologies such as Wireless USB (Wireless USB), Wireless HDMI or the Wi-Fi developments will seek to impose. With the format war (HD-DVD against Blu-ray), high definition is definitely a popular battlefield.
