Amimon, the Israel-based company behind the WHDI high-speed wireless standard, has shown a prototype system that uses the 5GHz band to transmit 3D HD video wirelessly. A demonstration transmitted 1080p 3D video at a frame rate of 24FPS, and the company plans to market a system that uses two boxes to send such signals between 3D HDTVs and a 3D Blu-ray player. The only cables required are power cables and HDMI cables that connect the Blu-ray player to the transmitter box and the TV to the receiver box.
The WHDI organization on Monday said it will release a new specification that will back all 3D formats supported the HDMI 1.4a. WHDI 2.0 is due, with full 3D support that includes the next-generation 1080p 60Hz x2 3D format. This will also bring with 4K HD format support that has four times the resolution of 1080p, at 4096x2160. WHDI and Wi-Fi can be integrated and exist on the same channel, along with reduced power requirements for integration with mobile devices will also be included in WHDI 2.0.
The WHDI wireless HD video standard that uses 5GHz, Wi-Fi-based technology has been finalized recently. The technology was found by chip designer Amimon and is one of at least four technologies aimed to bring wireless HD video distribution in the home. The technology will allow sending 1080p HD video at 60Hz refresh rates and 12-bit color depth up to 100 feet away and through multiple walls. Maximum data rates are said to be fixed at 3Gbps using a 40MHz channel.
AMIMON has announced several new chips designed for the Wireless Home Digital Interface (WHDI) standard, the AMN 2120 transmitter and AMN 2220 receiver. Both components work in conjunction with the company's RF transceivers, the AMN 3110 and AMN 3210, and support uncompressed 1080p/60Hz HD video and computer graphics, equivalent to video rates up to 3Gbps. The modems transmit on the 5GHz unlicensed band, which the company claims extends range beyond 100 feet even through walls. Dynamic Frequency Selection (DFS) is designed to reduce interference by automatically switching to the best channel.
Sharp has revealed itself as one of the first TV makers to officially embrace wireless video linkups for its TVs, according to news from DVICE. Upcoming versions of the company's AQUOS X-series HDTVs will include a slot for an Amimon-made WHDI (Wireless High Definition Interface) adapter that accepts both audio and video wirelessly from a matching transmitter; any HDMI devices plugged into the transmitter can broadcast at up to 100 feet away without a sacrifice in quality, including the native 1080p resolution and surround sound.
