San Francisco, CA, May 20, 2009 -- Media Vision USA has announced it will demonstrate the TAIDEN
fully digital Infrared wireless microphone discussion and voting systems along with the TAIDEN
language distribution system. The TAIDEN HCS-5300 and HCS-5100 series, with its excellent quality
and design, will be on display and demonstrated at the Media Vision USA booths during the InfoComm
2009 in Orlando, Florida.

The TAIDEN HCS-5300 fully digital Infrared wireless conference system brings the latest in digital
infrared technologies and networking techniques to the conference microphone. The TAIDEN HCS-
5300 Series consists of the Conference Main Unit CMU, Contribution Units (including delegate units,
chairman units, and interpretation units), digital IR transceiver units, and application software. HCS-
5300 system guarantees privacy as the infrared frequencies will not pass through walls or opaque
surfaces. The delegate units are powered by detachable, lithium battery packs that can be charged by
the HCS-5300CHG. The software allows users to quickly set-up, display, and save information about
each conference, and even in stand-alone mode, the HCS-5300 is competent for the management of
various meetings via several basic conference management facilities.

“The advantages of the TAIDEN fully digital Infrared wireless system are boundless, particularly in
complex conferencing settings that demand flawless and accurate delivery and execution,” states
Fardad Zabetian, president of Media Vision USA “We are pleased to offer our customers a
sophisticated and extremely portable conferencing system at very competitive pricing.”

Taiden HCS-5100 digital IR transmitter is capable of distributing a maximum of 4, 8, 16 or 32 audio
channels and able to maintain conference hall privacy as Infra-red is unable to pass through opaque
objects such as walls. During the adjournment, the music mode can be used to feed music to all the
channels. HCS-5100 Digital Infra-red radiator synchronizes with control unit for powering On/Off,
temperature control, and automatic gain control.

Further, the HCS-5100 receivers can display the name of each language on the corresponding
channel, making it easier for participants to locate the appropriate listening channel.

“By taking the Infra-red signal to the digital format, Taiden has dramatically raised the clarity of audio for
the listener,” said Wesley Sutliff, Product Manager of Media Vision USA. “We look forward to
integrating this product into systems that are in need of assisted listening, language distribution, or
both.”

The TAIDEN Digital IR Conference and Language Distribution System will be available throughout the existing Media Vision USA representation network in North America www.mediavision-usa.com/sales.html.
