WHDI, or Wireless Home Digital Interface, is a high-bandwidth, low-latency wireless solution that uses the 5 GHz band to move multimedia content between devices. This spec is so robust that it can support uncompressed 1080p video (in multiple rooms) and is virtually latency-free. That means WHDI can handle Blu-ray and 3D games with ease. And because 802.11n uses the same 5 GHz frequency, we could eventually see single chips that combine Wi-Fi and WHDI. WHDI promoters include Amimon, Hitachi, LG, Motorola, Samsung, Sharp, and Sony.
Available Gear: For now you can only get WHDI’s goodness by purchasing a PC-to-TV adapter kit such as the HP Wireless TV Connect ($199; www.hp.com) and the ASUS WiCast EW2000 ($199; us.asus.com). These packages require a dongle that attaches to your notebook and a receiver that connects to your TV.
What’s next: Later this year, ASUS will release the WAVI 3D, which wirelessly streams 3D content from a PC to 3D-capable TVs. By the end of 2011, look for WHDI to be embedded directly in tablets and notebooks, as well as smart phone sleeves. Haier has also signed up to use WHDI in its TVs. By the close of 2012, WHDI will likely be integrated into smart phones.
