What is Whdi in the video card?

Whdi (Wireless home Digital Interface, the Wireless Family Digital Interface) sets a new standard for wireless high-definition video connectivity. It provides a high quality, uncompressed wireless connection. The MIMO technology and the OFDM modulation method can achieve up to 3Gbps transmission speed.

Working in the 4.9ghz~5.875ghz band, 20MHz or 40MHz channels, in line with the global 5GHz spectrum, the range is within 30 meters, can penetrate the wall, and the delay is less than 1 milliseconds.

Whdi supports new devices, where consumers connect their A/V devices and consumer content to cover the entire family, Whdi allows users to connect any source in the home to any location display. Using Whdi, the TV in the living room can display the Blu-ray player in the bedroom, the HD DVD player, the kitchen TV can show the content on the Home Office PC, and the game entertainment can play in the basement projector, without the need to move the game machine from the children's bedroom or basement.

Whdi This new standard facilitates the use of uncompressed high-definition video transmission, independent video player, multiple indoor high-definition video connections using a revolutionary video modem approach to support the entire family.

WHDI specifies high-definition video transmission, as well as audio and control. The comprehensive WHDI control protocol will enable users to centrally control all A/V devices from the home, with virtually no latency, users will not encounter problems with voice and video asynchrony, or can use Whdi to connect to network entertainment audio and video games.

Whdi Features

Non-compressed video delivery

The most essential difference between WHDI technology and other wireless technologies is that it is capable of delivering full HD audio and video streaming without any compression. At present, the wireless transmission of video mainly through two ways: one is at the launch end through the compressed audio and video streaming wireless transmission, at the receiving end of the decompression to restore the image, WiFi and UWB technology as the representative. Another way is to transmit the video source output directly through the wireless mode video stream to the receiving end, the output image, to Whdi as the representative. At present, only Whdi technology can be realized in the industry.

Transfer without delay

Because Whdi technology provides enough wireless bandwidth, without compressing the way to transmit, save the video in the compression and decompression process of time spent, so can ensure that the transmission of film and television frequency is completely without delay.

Resolution up to 1080P

Whdi technology supports up to 1920x1080p video resolution. Subsequent upgrades through the software can support the resolution to 2K X 4K. Equivalent to 4 times times 1080P.

Supports 7.1 channels

In addition to being able to transmit Full HD video, Whdi technology can support 7.1 channel (PCM) audio transmission, sampling rate up to 24bit,192khz.

100K Return Channel

In addition to being able to transmit audio and video, the Whdi technology provides a 100K return channel. The purpose of the return channel is to enable the HDCP control protocol to authenticate each other between the transmitter and the receiving end. At present, the domestic WHDI module manufacturer World Alliance Company through the channel has realized the return function of USB keyboard and mouse, that is, UWTC (USB Wireless Transmission Control) technology, at the same time mastered the multi-touch of remote controls technology.

Support HDCP2.0 Technology

The HDCP organization has set HDCP2.0 technical standards for WHDI technology alone. HDCP2.0 can allow users to achieve a one-to-many, Many-to-many HDCP mutual authentication through WHDI technology. That is, HDCP2.0 technology allows a video source with a content protection protocol to be displayed simultaneously at multiple display terminals. This is completely impossible to achieve in the HDMI1.2 standard.
