Wireless television: WHDI technology promises wireless video throughout the home
Wireless audio has become more and more popular over the last few years, as technology has finally brought sound quality comaparable to wired systems. Unfortunately wireless video has lagged behind, leaving those of us yearning for a truly wireless home theater experience unfulfilled.
Hopefully, all of this is going to change in the next few years. Amimon, an Israel-based semiconductor company has developed the Wireless Home Digital Interface (WHDI), which promises to deliver high-quality wireless video throughout your home.
WHDI uses the 5GHz unlicensed band to transmit 1080p video at 60Hz with a latency of under 1 millisecond. It can transmit video at distances of over 100 feet. The transmission uses Hollywood approved HDCP 2.0 copy protection, which means that it should get the green light from movie producers who have been concerned in the past about all that copyrighted material being flung around wirelessly.
Currently, the chip is priced at $25, but as production increases, the price per unit is likely to drop. At such a low price, the WHDI chip is likely to get included in HDTVs, projectors, AV receivers, game consoles, computers, and basically anything else that uses or produces a video signal of some kind.
Imagine being able to watch wireless television from your wireless home theater system in your kitchen or bedroom at the same time, or even being able to watch the same video from every room in your house!
While the chipset is unlikely to be found in mass produced electronics for the next few years, the WHDI technology is likely to be available in outboard dongle-type devices within the year.
