Panasonic Corp prototyped an audio-visual equipment that supports "WirelessHD," a specification for wirelessly transmitting uncompressed HDTV video, and demonstrated it at CEATEC JAPAN 2008.

The company wirelessly transmitted uncompressed 1080p HDTV content stored on a Blu-ray disc by using 60GHz band milliwave. The maximum data transmission speed reaches 4Gbps.

Panasonic exhibited this system at IFA 2008, which took place in Germany in August. But this is the first time that the company has showcased it in Japan.

The company prototyped a PDP TV mounted with a WirelessHD receiving module, a tuner part equipped with a WirelessHD transmitting module, a home theater system and a Blu-ray Disc recorder. The company transmitted content from the Blu-ray Disc recorder to the tuner via HDMI and wirelessly transmitted it from the tuner.

Also, a Nintendo Wii, a home game console of Nintendo Co Ltd, was placed in Panasonic's booth because the company plans to demonstrate a collaboration with a video game by using the Wii. The company aims to highlight that, when used for applications like games, the WirelessHD causes little lag because of its uncompressed transmission.

On the module displayed at the exhibition site, a dedicated network processor and an RF transceiver IC integrated with an antenna were embedded. The network processor seemed like a product of SiBeam Inc of the US. On the RF transceiver IC, minute antenna elements are arranged in a grid pattern, realizing an adaptive beamforming.

Panasonic has already announced that it will commercialize an audio-visual equipment supporting the WirelessHD within 2009, and the company confirmed this plan. It displayed the prototypes to emphasize the concept of the equipment, making a strong effort like setting up an area dedicated for the equipment in its booth.
