1.4 System Techniques

1.4.1 IR radiation

Infrared simultaneous interpretation system audio signal is based on modulated infrared transmission.

Infrared is a part of the electromagnetic radiation spectrum. Electromagnetic radiation spectrum include

visible light, radio waves and other components of the radiation wave. Infrared wavelengths is higher

than visible light.

Infrared can not penetrate walls and ceilings to ensure the privacy of conferences and to avoid

eavesdropping and radio interference, in addition, infrared systems have no electromagnetic radiation

and no need radio frequency license.

1.4.2 Carrier wave and channel

GONSIN Infrared simultaneous interpretation system is transmitting within 2-6MHz frequency band. It

can transmit up to 12 different carrier signals(depending on the transmitter type). Carriers 0 to Carrier 11

are according to IEC 61603-7 (see Figure 1.4.2-a, band allocation see Figure 1.4.2-b).

Figure 1.4.2-a Standard band of IR SIS

Figure 1.4.2-b Band Allocation

1.4.3 Aspects of Infrared distribution

A good digital infrared simultaneous interpretation system ensures that all delegates in conference

venue receive the distributed signals without disturbance. This is achieved by using a sufficient number

14

of well positioned radiators, in such a way that uniform IR signal with adequate strength can be received

at any place of the conference venue. When planning an infrared distribution system several aspects

influencing the uniformity and quality of the infrared signal should be considered . These are described in

the next sections.

1.4.3.1 Ambient Light

GONSIN Infrared simultaneous interpretation system is transmitting within 2-6MHz frequency band. It

can be operated without any problem even if fluorescent lamps (with or without electronic ballast or

dimming facility), such as TL lamps or energy saving lamps are switch on.(See Figure 1.4.3.1-a Figure

1.4.3.1-b)

Figure 1.4.3.1 The interference band of the HF driven lighting system(fluorescent lamp)

Figure 1.4.3.1-b The infrared language distribution system using 2-8MHz eliminates disturbance from

high frequency lighting systems

1.4.3.2Objects, Surface and reflections

15

Just like visible light, infrared radiation is reflected from hard surfaces and refracted by hyaloids(glassy

or transparent appearance)objects. Both objects in the conference venue and structure of the walls and

ceilings will influence the distribution of infrared light.

Infrared radiation is reflected from almost all hard surfaces. Smooth, bright or shiny surfaces reflect

well. Dark or rough surfaces absorb a large part of the infrared energy. Normally surfaces opaque to

visible light are also opaque to infrared radiation.

Shadows from walls and furniture will influence the transmission of infrared light. This can be solved by

using a sufficient quantity of radiators. They should be positioned in a manner to provide an infrared field

strong enough to cover the whole conference area.

Take care not to direct radiators towards uncovered windows, or most of this radiation will be lost.

1.4.3.3 The footprint of the radiator

The number of transmitted carriers and the output power of the radiator determine the coverage area of

a radiator. The total radiation energy of a radiator is distributed over transmitted carriers. The coverage

area becomes proportionally smaller if more carriers are used, The receiver requires a strength of the IR

signal of 4 mW/m2 per carrier to work well(resulting in an 80 dB S/N ratio for uninterrupted audio

channels).

The cross section of the 3-dimensional radiation with the reception level of participants is the footprint

(the dark grey area in figure 4.1.3.3-a to 4.1.3.3-b). In this area, the direct signal is strong enough to

ensure proper reception when the receiver is directed towards the radiator. The size and position of the

footprint depends on the mounting height and the angle of the radiator.

Figure 1.4.3.3-a IR radiator and ceiling 15º

installation

Figure 1.4.3.3-b IR radiator and ceiling 30º

installation

16

1.4.3.4 Positioning the radiators

Because infrared radiation can reach a

receiver directly and/or via diffused reflections, it’s

important to take this into consideration when

installing the radiators. For best reception quality,

receivers should pick up direct infrared radiation.

In addition reflections will improve the signal

reception. In big conference halls, infrared signal

will be blocked by the people in front of the

receiver. For that reason the radiator should be

installed at an appropriated height, usually

2.8-4.5 meters.

For concentrically arranged conference venues,

radiators located high up and faced to the centre

from every angle can cover the area very

efficiently. If the direction of the receiver changes,

e.g. changing seat direction, the radiators can be

installed in the corners of the room.

If the the seating is always directed towards the

IR transmitting source, radiators are not

needed to be installed at the back, figure

1.4.3.4-a

Figure 1.4.3.4-a Radiator positioning in a

conference hall with auditorium seating and

podium

If the path of the infrared signals is blocked,

e.g. under balconies, at least one additional

radiators is needed to cover the ‘shaded’

area(see figure 1.4.3.4-b)

Figure 1.4.3.4-b Radiator for covering seats

beneath a balcon

1.5.1 Connection instructions

1. Connecting IR transmitter to interpreter console: the INTERPRETER UNIT interface of the IR

transmitter can be connected to INPUT socket on the interpreter console through a 25-pin cable,

OUTPUT socket to the INPUT socket in the next interpreter console, and so on.

2. Connecting IR transmitter to central control unit: the audio output socket in the central control unit can

be connected to AUDIO IN socket of CH0 in IR transmitter through an audio cable.

3. Connecting IR transmitter to external audio source: the audio output socket in external devices can be

connected to AUDIO IN socket of any channel on IR transmitter through an audio cable.

4. Connecting IR transmitter to IR radiator:

(1) the SIGNAL OUT socket in the IR transmitter can be connected to IN socket in the radiator through

coaxial cable. OUT socket of IR radiator can be connected to the IN socket of the next interpreter

console.

(2) After all connection of devices, turn on the power switch, the power indicator light is on to show the

power is connected.

(3) Turn TEST switch of IR transmitter to ON position, then LEVEL lights in IR transmitter panel are on

to show test tones frequency is transmitted. Please walk around the conference venue under the test

mode of the transmitter, test every position where the signal must be received. If an area is detected as

having bad reception or even no reception at all, please adjust IR radiator angle and power. After testing,

please turn TEST switch of IR transmitter to be Off.

(4) Interpreter console MIC ON, IR transmitter and other audio devices, choose incoming channel to

check receiver receive corresponding audio source.
