In the market for wireless transmission of high-definition video for consumer and mobile products, three Wi-Fi-based video technologies will outperform two proprietary technologies with narrower application ranges. Intel launched WiDi (Intel Wireless Display), which is a wireless display technology that uses WiFi signals to achieve wireless connection between computers and display devices. I believe that many friends are also exposed to this technology for the first time. How is WiDi implemented? What is the effect? ​​What applications can it achieve? The following article will tell you everything.

  NETGERA Push2TV (PTV1000) Adapter

  Before implementing the WiDi function, of course, some corresponding preparations must be made. First, you must have an adapter that supports the WiDi function, which is the same as the fact that we need to find a wireless router when we use the laptop to surf the Internet wirelessly. The adapter we received for this review is a NETGERA Push2TV (PTV1000) adapter. Since the WiDi technology has just been launched, such a WiDi adapter has not received strong support from network equipment manufacturers. The cheapest price of this adapter is about 800 yuan.

HDMI interface and AV interface

  The NETGERA Push2TV adapter looks almost exactly the same as a common wireless router, with a piano black exterior color and a built-in transmitting antenna. The difference is that in addition to the power interface, the back of the body also includes an HDMI video output interface and an RCA audio and video output port. It relies on the 2.4G 802.11n protocol for video and audio transmission. When the adapter is connected to the power supply, the indicator light on the front is orange to indicate that it is not connected. When the indicator light turns green, it means it is connected.

  Wireless network card models supported by WiDi technology

  The realization of WiDi wireless display function requires the cooperation of the adapter and the wireless network card of the laptop, but not all laptops equipped with wireless network cards can realize wireless display technology. The main reason is that the wireless network card model must meet the requirements of WiDi construction, which also virtually raises the threshold for realizing wireless display technology. The following are the software and hardware requirements for building the platform:

  1. The laptop needs to be equipped with an Intel Core family processor and HM55/HM57/QM57/QS57 chipset. Low-voltage and ultra-low-voltage processors are not currently available. (Current mainstream laptops can basically meet these requirements)

  2. WiDi technology currently only supports three Intel wireless network cards Advanced-N 6200/6300/1000

  3. The laptop needs to be installed with Windows 7 operating system.
