Transmitting full HD video shot with a camcorder to a thin-panel TV via radio easily allows it to be enjoyed on a large screen. Matsushita Electric Industrial Co Ltd demonstrated such a system at a keynote speech on the opening day of 2008 International CES.

Toshihiro Sakamoto, who is president of Panasonic AVC Networks Company and delivered the keynote speech, conducted the demonstration himself and transmitted video from a camcorder to a TV without using complicated wirings, showing before a crowd of audience that it was easy to enjoy video on a large screen just after shooting it.

After introducing the company's 2.47cm-thick slim PDP and 150-inch PDP, Sakamoto started to talk about the advent of a time, where HD video can be transmitted via radio. He demonstrated wireless transmission of video from a BD player to a large screen display at first.

Then a woman with a camcorder in her hand came onto the stage and started shooting Sakamoto. A man holding a bundle of wire and a huge pair of scissors appeared next. Receiving the huge scissors from the man, Sakamoto dramatically cut the bundle of wire. At that instant, the room was filled with laughter.

I did not recognize it at the time, but the woman holding the camcorder was shooting these actions all the while. Receiving the video recorder from the woman, Sakamoto placed it on a wagon, in which a BD recorder was housed. Then the video that had just been recorded was transmitted and archived to the BD recorder right below the camcorder.

When Sakamoto attempted to replay the video using a remote controller, video was transmitted to the large screen display from the BD recorder via radio just like the demonstration at the beginning. And Sakamoto receiving huge scissors and dynamically snipping off the bundle of wire was displayed on the large screen. The audience burst into laughter again and the room was filled with excitement.

The HD video wireless transmission system demonstrated this time is based on "WirelessHD" radio data transmission technology using 60GHz band milliwave. Using the 60GHz band, which can be internationally used without license, the technology can transmit data via radio at up to 4Gbps.

The system can exchange uncompressed full HD video between AV equipment including TVs and BD players, without degrading video quality. Matsushita named this technology "Beam Steering Technology," claiming it enabled the system to stably transmit data even if obstacles including humans are interfering radio between the transmitter and the receiver.

Matsushita is demonstrating the wireless data transmission system at the CES exhibition site as well. The company demonstrates wireless transmission of video from a BD recorder to a 2.47cm-thick 50-inch wall-mounted PDP, which was unveiled for the first time at this CES. Matsushita plans to commercialize the wireless transmission system in 2009.
