Chapter 1. Introduction Digital Congress Network (DCN)

The BOSCH Digital Network System (DCN) provides flexible control facilities for all types of conferences from small discussion groups to international, multi-lingual congresses with hundreds of delegates. Facilities range from basic microphone management, to delegate identification and registration, electronic voting, information distribution and display, up to extensive simultaneous interpretations and automatic camera control. A single operator using a computer with DCN’s application software can control even the largest of congresses. Systems can be expanded by adding more contribution equipment and introducing PC control with DCN’s application software.

The full range of DCN equipment includes:

1.Contribution equipment

2.Central control equipment

3.Simultaneous interpretation and language distribution equipment

4.Information display equipment

5.Application software packages

6.Installation equipment

DCN equipment is also complemented by external equipment such as video and character displays, TV cameras, personal computers, monitors, PA amplifiers, loudspeakers and printers all of which are fully compatible and easily integrated into the DCN system.

1.1Contribution equipment

Contribution equipment describes the units which participants use to contribute to a conference. Depending on the type of contribution unit, delegates can access the DCN’s wide range of facilities to listen, speak, register a request-to-speak, receive screen messages, communicate with other delegates via an intercom and to participate in electronic voting sessions. On insertion of an ID-card dedicated software is required giving much more facilities.

Contribution units can be used free-standing on a table-top, or flush-mounted in desks, seat backs or armrests. Other microphone types such as lavalier and hand-held are also available, allowing contribution from non seated participants such as a guest speaker for example.

1.2Central Control Equipment

The Central Control Unit (CCU) forms the heart of the DCN system.The CCU can operate stand- alone to provide automatic conference control, or it can be accessed by an operator via a personal computer (PC) when more extensive management control is required.

All CCU’s can control up to 240 contribution units. If more capacity is required, slave CCU’s can be connected, each of which increases the system capacity by 240 contribution units. A maximum of 16 slave CCU’s can be connected to a system. Other extension units include an Extension Power Supply unit and an Audio Media Interface unit which extend the systems power handling capacity.

The CCU offers basic microphone management, simultaneous interpretation and electronic voting facilities, as well as digital audio channels, data channels and communication channels.This allows effective unsupervised control of even large or international conferences. The extended CCU offers all the facilities of the basic CCU, but allows operator control via a personal computer (PC).The operator can access the wide range of DCN application software packages, each with a specific function in controlling and monitoring conferences.This includes advanced simultaneous interpretation and microphone management, message generation and display, voting procedures, intercom, creating a delegate data base, attendance registration, audio processing and automatic camera control.
