Audiovox HDP100 Transmits HDMI Over Existing Powerlines

Redistributes HDMI content throughout home without need for additional cabling.

Audiovox may have found the retrofit Holy Grail for some consumers and custom installers.

The company’s new HDP100 HD Powerlink system is a wireless HDMI transmission system that uses a home’s existing powerlines to transmit audio and 1080p video throughout a home.

Dave Crupi, senior product manager for Audiovox, says the system, shipping under the Acoustic Research brand, offers a solution that can be used in existing and new homes to distribute HDMI without additional cabling.

“In terms of how its packaged, it comes with one receiver, one transmitter, HDMI cables, a wall mount kit, a stand-up kit, a quick-start guide and a full owner’s manual.”

Crupi says the system includes provisions for IR control and, despite its emphasis on the retail channel, the system has been well received by custom installers.

“It was designed and it is marketed to retail, but we are also marketing to various CEDIA dealers,” he notes. “Frankly, at the last CES we showed it to them [custom installers] and they were excited about it because in a retrofit, they can use it instead of crawling on their bellies pulling cables.”

Audiovox took the system into various homes to see how it would operate in different environments. He says while they did find limitations in older homes with deteriorating copper, they’re still comfortable with its performance.

Crupi says the system is being marketed as a single-room solution, but Audiovox realizes it will be used in a number of scenarios, providing it isn’t plugged into a power/surge protector or share space with other PLC (power line carrier) products.

“The basic agreement with Homeplug and Panasonic [the chip maker Audiovox is using] is that they could work together,” says Crupi.

“You may be limited — and they may not interfere — but it puts extra burden on the line in the space PLC system operate on the in the 28MHz to 40MHz range. Also, we do not recommend that people plug these [the HDMI devices] into GFIs, surge protectors and power conditioners.

“These products protect against anything other than 60Hz and you may be sending a lot of your signal to ground. Our boxes are protected with their own surge protection.

“We don’t recommend you plug it into an external surge protector.”

MSRP: $400
