Live commentaries from the stadiums, editorial and technical communication and many other important tasks will be carried out by MAYAH Centauri / Centauri II Audio Gateway Codecs during the Football World Cup in June and July this year. More than two hundred units of the type CENTAURI and MERK will be used by the main German TV and Radio broadcasters such as WDR (being in charge of ARD, 1st TV Channel and Association of Public Broadcasting Corporations), ZDF and RTL, the largest private TV station. Also many more International radio/TV stations.
Beyond the common applications the TV channels are organising the centralised translations and interpreting live interviews for the foreign guests. The original sound will be transported from the locations to the TV headquarters to haul back the dubbings and then distribute them via traditional channels.
The second channel of German television, ZDF, also plans to deploy the codecs at some external events – football teams trainings, the Opening Gala, a “Fanfest” in Berlin and many others.
Depending on the connection architecture of each broadcaster MAYAH Centauri and Centauri II Audio Gateway Codecs will transmit the signals over X.21 or ISDN networks and secure the best sound quality for the main signal route along with various back-up installations, including the back-up for traditional OB van connectivity. |

 Eurovision Song Contest has been the largest annual pop-music and media event in Europe for exactly 50 years. Current TV audiences for the show average 100 million people. This year the show takes place from 18th to the 20th May at the Olympic Indoor Arena in Athens, Greece.
37 countries will send their best artists to take part in the competition. The scale of the technical preparations made for the project are huge.
To make the difficult job of national commentators and their technical teams easier, and to unify the support workflows, technical supplier of the event TVN (Germany) rented 50 of MAYAH’s Portable Gateway Codecs, MERK II. The desktop devices combine the strengths of a powerful audio codec and a small digital mixer. Up to four professional microphones and headphone sets can be plugged into the MERK II. While still leaving analog and digital AES/EBU inputs and outputs free. MERK II can operate over IP, ISDN or X.21 networks using 15 major professional audio coding algorithms, including the entire MPEG range, Eapt-X and more.
Installed in every commentator’s booth, MERK II will transmit over ISDN networks to the national TV channels broadcasting the Contest. |

MAYAH Centauri II and MERK II go SIP
SIP: Session Initiation Protocol (RFC 3261)
This protocol is developed by the IETF (Internet Engineering Task Force) as an alternative to the H.323 Standard. Together with other protocols it allows to establish, control, terminate and modify point-to-point and multipoint connections.
As a client-server protocol, SIP is similar to HTTP. Its requests and responses are the text strings containing the information about conversation signalling.
SIP is responsible for the whole connection signalling, localisation of users and registration. Quality-of-Service, directory access, as well as description of the session and conferencing are not handled by SIP, rather by other protocols.
Modular structure of the SIP allows smooth co-operation with H.323. So the calling side can localize its partner and signalise, that a communication will be held over H.323 protocol.
Since SIP only provides the session framework (establishment, modification and termination of a connection) a number of protocols can be utilised to support and expand its functionality.
At present time some of the protocols integrated with SIP are:
| - |
RVSP (Resource Reservation Protocol) for reservation of network resources |
| - |
TCP/UDP for transmission of SIP data |
| - |
RTP for transmission of media data |
| - |
RTSP as a support for session establishment |
| - |
SAP for sessions with multiple participants |
| - |
SDP to negotiate the transfer mode |
An integration of telephone networks is provided by the ENUM protocol (Telephone Number Mapping), which enables a transparent connection establishment to and from IP based nets.
The complete separation of signalling and transport layer (i.e. of connection data and media data), as implemented in SIP allows for the user to establish a connection in a unified way without prior knowledge of the exact location of other participants and not depending on the nature of the transferred data.
The constantly growing acceptance of SIP - due to recent developments in fields like Internet telephony and UMTS - guarantees for a steady growth and expansion of infrastructure, which can then be used for other applications.
