We've been hearing about wireless streaming of HD content for some time now but so far – besides a few Wi-Fi based solutions that require some sort of compression – few products that can actually handle it have trickled out to the market. Now, a group of consumer electronics and wireless technology developers have partnered to jointly develop yet another industry standard
for wireless high-definition video.
Wireless Home Digital Interface, or WHDI, is based on technology from an Israel-based company called Amimon which makes the wireless chipset driving the technology. Theoretically, it can support data rates of up to three gigabits per second, which is enough to send uncompressed high-definition video signals over the unlicensed 5-Gigahertz band.
WHDI will being going up against other technologies designed to stream high-definition signals such as WirelessHD
. A major difference between the two, however, is that the former can go through walls and keeps bandwidth usage low. According to Amimon, WHDI-enabled TVs should be available next year costing around $100 more than a set without the technology. And in three to five years (or when shipping volumes reach 10 million) it should only cost $10 extra to have the technology inside a variety of devices.
