INTEGRUS | Digital Infra-red Language Distribution System en | 5 1 System description and planning 1.1 System overview Integrus is a system for wireless distribution of audio signals via infra-red radiation. It can be used in a simultaneous interpretation system for international conferences where multiple languages are used. To enable all participants to understand the proceedings, interpreters simultaneously translate the speaker’s language as required.
| en INTEGRUS | Digital Infra-red Language Distribution System Infra-red receivers Two multi-channel infra-red receivers are available: N LBB 4540/04 for 4 audio channels N LBB 4540/32 for 32 audio channels They can operate with a rechargeable NiMH battery pack or with disposable batteries. Charging circuitry is incorporated in the receiver. Charging equipment Equipment is available for charging and storing 56 infra-red receivers. It is available for portable or fixed-installation applications.
INTEGRUS | Digital Infra-red Language Distribution System en | 7 1.2 System technology 1.2.1 IR radiation The Integrus system is based on transmission by modulated infra-red radiation. Infra-red radiation forms part of the electromagnetic spectrum, which is composed of visible light, radio waves and other types of radiation. It has a wavelength just above that of visible light. Like visible light, it is reflected from hard surfaces, yet passes through translucent materials such as glass.
| en INTEGRUS | Digital Infra-red Language Distribution System 1.2.3 Quality modes The Integrus system can transmit audio in four different quality modes: N Mono, standard quality, maximum 32 channels N Mono, premium quality, maximum 16 channels N Stereo, standard quality, maximum 16 channels N Stereo, premium quality, maximum 8 channels The standard quality mode uses less bandwidth and can be used for transmitting speech. For music the premium quality mode gives near CD quality. 1.2.
INTEGRUS | Digital Infra-red Language Distribution System en | 9 1.3 Aspects of infra-red distribution systems A good infra-red distribution system ensures that all delegates in a conference venue receive the distributed signals without disturbance. This is achieved by using enough radiators, placed at well planned positions, so that the conference venue is covered with uniform IR-radiation of adequate strength.
| en INTEGRUS | Digital Infra-red Language Distribution System " & Figure 1.6 Polar diagram of the radiation pattern for 1, 2, 4 and 8 carriers The cross section of the 3-dimensional radiation pattern with the floor of the conference venue is known as the footprint (the white area in Figure 1.7 to Figure 1.9). This is the floor area in which the direct signal is strong enough to ensure proper reception, when the receiver is directed towards the radiator.
INTEGRUS | Digital Infra-red Language Distribution System 100% 40% 100% en | 11 80% Figure 1.10 The texture of the material determines how much light is reflected and how much is absorbed Problems caused by shadows from walls or furniture can be solved by ensuring that there are sufficient radiators and that they are well positioned, so that a strong enough infra-red field is produced over the whole conference area.
| en INTEGRUS | Digital Infra-red Language Distribution System Figure 1.13 Combination of direct and reflected radiation Figure 1.14 Combination of several reflected signals For concentrically arranged conference rooms, centrally placed, angled radiators located high up can cover the area very efficiently. In rooms with few or no reflecting surfaces, such as a darkened film-projection room, the audience should be covered by direct path infra-red radiation from radiators positioned in front.
INTEGRUS | Digital Infra-red Language Distribution System en | 13 Figure 1.17 Radiator for covering seats beneath a balcony 1.3.6 Overlapping footprints and multipath effects When the footprints of two radiators partly overlap, the total coverage area can be larger than the sum of the two separate footprints. In the overlap area the signal radiation power of two radiators are added, which increases the area where the radiation intensity is larger than the required intensity.

The height is the distance from the reception plane and not from the floor.
INTEGRUS | Digital Infra-red Language Distribution System en | 15 1.4.3 Cabling Signal delay differences can occur due to differences in the cable length from the transmitter to each radiator. In order to minimize the risk of black spots, use equal cable length from transmitter to radiator if possible (see Figure 1.23). 50m 50m 50m 50m Figure 1.
| en 1.5 INTEGRUS | Digital Infra-red Language Distribution System Setting the radiator delay switches As described in section 1.3.6, differences in the delays of the signals picked up by the receiver from two or more radiators can cause black spots as a result of the multi path effect.

| en INTEGRUS | Digital Infra-red Language Distribution System 1.5.3 System with more than 4 carriers and a radiator under a balcony Figure 1.29 illustrates a situation in which a radiation signal delay occurs and which can be compensated for. For systems with more than four carriers, add one delay switch position per 10 meter (33 feet) difference in signal path length to the radiators which are closest to the overlapping coverage area. In Figure 1.29 the signal path length difference is 12 meter.
INTEGRUS | Digital Infra-red Language Distribution System en | 21 1.6 Testing the coverage area An extensive reception quality test must be done to make sure that the whole area is covered with IR radiation of adequate strength and that there are no black spots. Such a test can be done in two ways: Testing during installation: 1. Check that all radiators are connected and powered up and that no loose cables are connected to a radiator.
