Chapter 1 Overview
VIS-VLI700A-8 8 channel transmitter
VISSONIC independently developed this system,
which applies full-digital modulating technology.
With this system, the translator simultaneously
interpreting the language according to the speaker’s
original voice and the translated languages are
transmitted to the whole meeting hall via modulated
IR and can be received by the delegated with the
earphone and the IR receiver with preferred channel
on the language they understand.
Digital IR Simultaneous Translation System is a
system using IR to transmit voice. Because light
travels in straight lines, there is no signal outside of an
enclosed room, thus, it has very good confidentiality.
Within the room, due to the scattering and diffusion of
the IR light on the surface of the wall, floor, ceiling,
the IR signal will form a compact light net. As long as
it is within the range where the IR light can cover, the
receiver can be allocated randomly.
This system can also be used for other applications,
such as music distribution. It has high precision
working frequency, stability, high confidentiality, and
is interference and eaves-dropping proof. This system
can be applied in international meetings halls from
small to large scale, or in multi-language education
organizations.

System Advantages
Digital IR Language Distribution System
includes transmitter, radiator, IR receiver and charging
box. The transmitter encoding the audio signal,
compresses, modulate it to many carrying waves and
then transmit it to the radiator. The radiator emits the
carrier signal via IR light. The IR receiver receives,
modulates and converts the signal into audio output or
other data. They have the following advantages:
◆
Apply simultaneous interpretation
It is important to allow every delegates hear
clearly in a multi-language conference system, thus,
a simultaneous interpretation system is a
