The prospect of a wireless HDMI standard has taken a step closer to reality with the news that Tzero Technologies has partnered with Analog Devices to commercialise an ultra wideband (UWB) HDMI solution.
“Wireless HDMI lets consumers eliminate the cost and complexity of hard-wired connections, for which even short cable runs can cost hundreds of dollars,” explains Mike Gulett, president and CEO of Tzero. “Our offering enables manufacturers to build devices that can take advantage of high-definition content wirelessly and create entertainment networks capable of taking video programming anywhere in the home.”
“We explored several UWB technologies that work with our JPEG2000 video compression technology to enable wireless distribution of DVD-quality and HD video,” says Bill Bucklen, Director of the Advanced Television division of Analog Devices. “We expect to see ultra wideband become the standard for high-definition wireless video.”
Specialist cable and connection company Gefen says it plans on being the first provider of consumer and professional AV to develop products based on the Tzero/AD design: “We have investigated dozens of alternative solutions over the past years, and finally have found one that meets our stringent requirements for wireless HD video distribution,” says Gefn president Hagai Gefen. “We believe wireless HDMI will revolutionize the way people connect their high definition displays, and are fully prepared to harness this technology to enable a reliable extension of high definition video without cables.”
How it works
The wireless HDMI solution consists of a transmitter and receiver. Video data is compressed using Analog Devices’ ADV202 JPEG2000 video codec, combined with audio, then packetized and encrypted, and transmitted via Tzero’s RF chipset.
At the receiver end, the audio/video data with HDMI is decompressed and presented to the display device via the HDMI port. The output to the HDTV is industry-standard HDMI v1.2 and complies with HDCP (High-bandwidth Digital Content Protection).
