WiDi – What is WiDi technology?

WiDi (Intel WirelessDisplay), also known as wireless high-definition technology, connects computers and display devices wirelessly through WiFi signals. After Intel released the Capella mobile platform, WiDi technology has been able to be applied in related products.

In the IT field, there are many devices that support wireless transmission, such as wireless keyboards and mice, wireless network cards, wireless headphones, etc. This also reflects the high demand for wireless devices among consumers. For laptop users, they only need to install the Intel Centrino Advanced-N 6200/6300/1000 wireless network card to wirelessly connect through a wireless receiving adapter and display device.

WIDI supports USB callback function. Whether it’s a TV or a box, there is usually a USB interface, so WIDI can simulate the USB port on the receiving end as a transmitting end, such as the USB port on the PC end. That is to say, insert a USB drive on a TV USB that supports WIDI, and users can access this USB drive on their computer. In the future, you can even plug in a camera on a TV that supports WIDI. This camera will also become a computer client, allowing Skype to be done through the computer,”said Gao Yu. The concept of USB backhaul is very practical.

Not only for consumer products, WIDI’s usage scenarios are also targeted at the commercial market. For example, projectors that support WIDI often require projection by business people, but the cable often cannot be connected, which is very troublesome. Especially after the Ultrabook was launched, many laptops had their VGA ports removed, and many projectors could only connect to VGA. After combining WIDI with a projector, this problem was solved very well. Notebooks that support WIDI can directly support it by pressing two keys.

In addition, INTEL can also provide a set of SDKs on the transmitter, encouraging more software vendors to develop differentiated multi-screen interactive applications. For example, the screen display content of the transmitter and receiver can be mirrored or different. For example, my computer displays a work interface, while the TV interface displays an entertainment interface, so that you can work while others can enjoy videos on your computer through WIDI. Even when playing games, the TV can display the game control interface, while the computer can display other perspectives of the game, which can bring more different gaming experiences. INTEL can provide SDK audio and video experiences that can be fully guaranteed, such as 1080P and 5.1 surround sound, which can achieve cinema level sound enjoyment.
