Intercommunication technology Riedel Communications was fundamental during the Olympics. He also joined Formula 1 throughout the year. Here we tell you how were the facilities.

After a full year of planning and preparation, Riedel Communications provided a dozen organizations and equipped approximately 40 50 locations with tons of communications equipment during the Summer Games 2004 that were held in Athens.

Topped the list of customers Riedel, the Hellenic Olympic Committee (ATHOC) and the host organization broadcasting Of the games, Athens Olympics Broadcast (AOB). Thomas Riedel, the company's founder, and his team of more than 100 engineers, equipped the locations in Athens, Thessaloniki, Patras, Olympia and Crete with intercom equipment covering all events.

In all, teams Riedel matrix systems used 80, 2.000 over control panels digital intercom, digital transmitters and 3.000 1.000 analog radio; 200 radio interfaces Ri Face, hearing aids and more than 5.500 200 kilometers of cable and fiber. During all competitions, teams were in service Stand by To supply backup units in case of failures.

Athoc gave Riedel the responsibility of all communications related to the sport. At events, Riedel Artist S Matrix systems enabled 1.200 participants to communicate with each other simultaneously. The referees, timekeepers and field assistants were communicated through 1.000 Beltpacks C2 digital, officially presented in the IBC of Amsterdam but successfully tested under real conditions in Greece. The robust and ergonomic package, completely free of noise, has quality Broadcast And is unique in its ability to provide an integrated solution for matrix and style intercom mounts party line. "Our new C2 allows customers to communicate in a similar fashion to analog style systems party lineIncluding networking in daisy-chain and power supply for the same wiring. Additionally, we are able to offer all the advantages of matrix systems Such as route assignment flexible ", said Thomas Riedel, managing director of Riedel Communications GmbH.

AOB - which supplied images for all television stations in the world - used more than 800 analog and digital radio transmitters, including Riedel hearing aids. The Artist S digital matrix system provided the connections between the AOB headquarters and the teams that worked in the different locations. In addition, around 200 interfaces RiFace provided the integration of intercom systems by cable and wireless. Riedel engineers not only installed radio systems for cameramen, sound engineers and directors, but also a complex network of filters to ensure interference-free operation, even under heavy loads caused by other radio operators.

Initially, Riedel became involved with Sports Events 2003, the official tests for the Olympics, when the company worked with its partner Greek systems PTS Pierides Technosystems Ltd. Reliability applications intercom and radio was confirmed and began planning for the supply of the Summer Games.

In addition to the two "Olympic" missions, a significant number of Riedel teams were present at the Greek facility. Alfacam, the largest European truck operator -OB and long-time user of Riedel equipment, was present with its multimedia platform Artist. In Greece, Artist allowed the installation of a huge intercom system for AOB production equipment, consisting of several trucks, taking advantage of his particular ability to connect in a decentralized way through a fiber network.

Many other radio stations around the world also depend on Riedel technology: ARD and ZDF (Germany), BBC (UK), TVE (Spain), ERT (Greece) and NBC (USA) communicate through matrix And, or, Riedel radio systems. Matrix Has also been used at Athens International Airport and by security services.

Two hundred kilometers of cable and fiber
Infrastructure difficulties and the need for high safety standards, including checking each unit relaunched
installation of all systems, which used 200 kilometers of cables and fiber. Marc Schneider, project manager for the Olympics Riedel 2004, commented: "With the Olympic Games 2004 have proven that our systems are 100% reliable and can handle any logistical challenge, even under extreme conditions."

Riedel's extensive experience with logistics challenges, including Formula 1 races, world championships and various Olympic Games, has paved the way for smooth operations.

Riedel will continue to serve global nature events in the future. "We use the events of this magnitude, as a source for our product development. We are not just technology manufacturers intercom, but we are also committed to maintaining the equipment of our customers. Our goal is to develop practical solutions from our practical experience. That is a benefit to all our customers, from the smallest business to the largest, "says Riedel.

The formula used 1 Riedel Artist intercom

In an atmosphere of maximum speed, where bad communication can cost the victory -or a life-, Riedel's Artist intercom matrix has been adopted by the worldwide organization of Formula 1, FIA, and the 1 Formula teams, as the standard communications platform in the 18 races of the 1 Formula World Championship. Artist Riedel's matrix is ​​used in all careers to communicate to employees, staff pits and drivers.

Grand Prix races, geographically dispersed, taking place from early March to late October and are held on five continents. The different climates of places where you run and difficulties in transport conditions, require a robust communications system, capable of operating at its maximum optimum level in extreme weather conditions: rain, excessive heat, cold and moisture.

The system configuration consists of nodes Artist S 16, 50 approximately boards (RCP-1012E, RCP-1028E, DCP-1016E), a digital radio receivers digital and analog radio repeater-all analog receivers equipped with headsets Max and six interfaces for connecting radio channels RiFace digital radios, like analog radios, the Artist.

An Artist node is installed in each pitIn an isolated bad weather shelf, at least one board connected to each node. Additionally, internal radio signals from each team, are connected to these nodes.

the Artist nodes are also used in the mechanical workshops of the FIA ​​and trucks. Also in the control center of the race additional boards and recording systems on hard disks are connected, like data logging. A board is installed on the platform of the starting line, where light signals are activated and start and finish flags shown.

Artist allows computers to communicate remotely with race control while receiving information from race director. "One of the main reasons that Artist has been chosen for racing Formula 1 is safety in privacy. It eliminates the possibility of interception and communications are heard indiscreetly. It is impossible to violate the system because all communications are digital proof to be heard by others. If another cable is connected somewhere or cut, an alarm is activated, "said Thomas Riedel.

Max headphones, Riedel, developed especially for Formula 1, are another critical component in the composition of the system. Max hearing aids are designed to allow clear communications, although all race cars pass at the same time for the same place.

The board of each team is also equipped with a flashing light, controlled by the local GPI contact of the board. A call of the control of the race to a team, is indicated by means of this flashing light. Otherwise, an incoming call would be impossible to detect due to competition noise. With the help of logic functions, the system is programmed so that when the race control calls a team (or vice versa), the key flashes and the audio is only transmitted once someone acknowledges the call by pressing a key.

Riedel designs, produces and distributes the most sophisticated radio and intercom technology for customers worldwide, for the communications, professional audio, events, sports and theater industries. The products reflect today's state-of-the-art technology, which extends conventional concepts to tomorrow's applications. The Riedel group of companies also includes a large leasing division, which provides complete radio and intercom services, as well as audio and video transmission systems based on fiber optics. The company, founded in 1987, today employs more than 100 people distributed in five locations in Europe and North America.

Challenges in the words of Riedel
Andreas Hilmer, manager of marketing and corporate communications from Riedel Communications GmbH, answered the following questionnaire TV and Video.

What kind of obstacles did Riedel when he designed and implemented intercom systems for racing and Formula 1 Olympic competition? What were the main differences between the designs of both systems?

-Generally, The process of design and implementation of intercom systems for sporting events, is always quite similar. The difference is the selected architecture, which depends on the event, sport and customer requirements. In Athens, the challenge was mainly to provide logistics services in different competitions in 48 37 events with a maximum distance of 500 kilometers, while in Formula 1 is the complexity of the system.

What are the main factors taken into account when designing an intercommunication system for a major sporting event? What is the functionality that the system is supposed to have? What needs should you fill?

-The requested functionality of the system is based in advance on existing equipment in a Formula 1 team or previous experiences (such as the Olympic Games in Salt Lake or Sydney). For example, the main mission in a Formula 1 team is to ensure pits or pits pilots race. This mission must be perfected through knowledge of the team structure and communication channels within the team, to develop the system design and the basis for programming the matrix. It is important to know that the system can not be mounted once for all. The communications system is a 'living' drive to keep its flexibility along the 18 races of the season. It should be as flexible as the car, the racing driver and equipment, to react to any unexpected circumstances.

In the case of the Athens Olympics, the main structure of the communications system has existed since the Sydney Games. Riedel was the mission of adapting to different locations, changing rules (sports) and new users, including their requirements within a completely new system, which had not been applied before in Olympic Games. Using Artist S as the central matrix, and the new Digital Beltpack C2, allowed the design team of the matrix and engineers, react immediately to the needs and problems of users, simply by programming matrix. This made the wiring changes were obsolete and saved a considerable amount of time.

What are the main technological innovations in intercom systems?

-From Our point of view, the main technological innovations intercom systems are decentralized concepts without master digital matrices which provide increased scalability reduce the cost of cabling and staff and allow the integration of different types of media one platform-, the main link via fiber units which allows to mount these decentralized systems and matrix- beltpack digital, Riedel recently introduced at IBC in Amsterdam. The digitization of BeltpacksFinally takes the audio quality of partyline at the level of Broadcast And, therefore, offers the integration of broadcast and intercommunication applications.

How do you integrate the remote links to your system? Does IP play a role in this?

Artist's main unit provides standard Ethernet to integrate the system into TCP-IP environments. Configuration is done by the Director software, which runs on standard personal computers (PCs). Due to the decentralized structure of the Artist platform, the PC does not have to be connected directly to the desired main unit, but can be connected anywhere in the Artist network. Configurations of any host system can be done from anywhere on the system. IP also plays a role in integrating the matrix with the public network infrastructure. In addition to the Connect Digital Telephone Hybrid, Riedel also offers voice over the IP interface.

Is it possible to integrate these systems to data networks?

- As already mentioned, Riedel provides voice through IP interface, which allows the integration of VoiP-based equipment with the matrix. Another thing: CAT5's existing structured cabling networks can be easily used to connect control panels (eg 1000 series boards) or Beltpacks (The C2) to the matrix. In this way, a CAT5 infrastructure saves time and money in the system wiring.

Do these systems and designs are made for smaller scale events?

-Of course. This matrix system will accommodate any event class. You can consider a basic system working independently, composed of a main unit Artist S and some control panels. As your needs increase, you can link multiple systems via fiber to achieve a huge array system.

Is there support elements and systems of a third party?

No, not directly. No compatibility of components and systems Artist with elements of a third party when you think integrate dashboards or matrices of a third party. This is because Riedel is the only company that provides connections fiber main units, decentralized and no master. To do this, Riedel has developed its own protocols and standards to achieve transmission speeds necessary. But Riedel offers a wide range of interfaces that integrate third-party products with the matrix. For example, with the Artist 1D (which still has not been officially announced), the Artist platform can connect to Yamaha PM1D. Another example: ADT-208 of Adat interface for the main unit S Artist (presented at IBC 2004) provides Toslink input and output for connection to a wide range of digital mixing consoles, routers, multitracks, preamps, etc.
