COMMENTARY SYSTEM - SYSTEM CONCEPT
Ahead of the game: Networked Commentary System for both Big and Small Broadcast Events
oratis is a premium-class commentary system. Easy-to-use commentator terminals are connected directly to a top-class audio router which also acts as an I/O matrix. The components are networked redundantly over standard Gigabit Ethernet cabling and can also be integrated into an existing infrastructure on a managed network.
oratis allows networks with more than 350 commentator terminals to be set up – each accomodating up to three commentators. Thus, even the largest international events, feeding multiple broadcasters, can be furnished with a uniform commentary system. Operation is simplified and the audience experience enhanced.

The system can be connected to the audio infrastructure through additional interface cards which are available for all standard audio interfaces.
COMMENTARY SYSTEM - APPLICATIONS
oratis systems grow with your needs: They adapt perfectly to any and all requirements.
One of the most common applications of commentary systems is sports events. Today, many large sports venues are already equipped with managed gigabit networks. This enables an oratis commentary system to be installed almost instantly. Only short patch cables from the OB truck to the stadium patch bay and from the stadium network to COM 3 need to be connected. This reduces wiring requirements and system set-up time to the bare minimum!
COMMENTARY SYSTEM - SAFE AND SECURE
With Certainty: oratis is always ready for action
An oratis commentary system will not let you down. From the ground up the design concept embodies maximum reliability, avoiding any single point of failure thanks to distributed intelligence.
The TDM busses on the matrix frames utilise a passive design which offers optimum confidence and security. In addition, all components of an oratis system are actively monitored and any malfunctions are signalled immediately and clearly.
For increased reliability, connections between the commentator terminal and the matrix frame can be made redundant. And even in the worst moments, the integrated breakdown function will not forsake you: in case of total line failure, it supports broadcasting using cell phones. All oratis components are hot-swappable.
Be it a commentator terminal or a full matrix frame – each module can be replaced or even be added during operation. This allows for system extensions and full reconfiguration without the need for a reboot. Even very large oratis systems such as installations for international sport events remain flexible, versatile, and maintainable.
COMMENTARY SYSTEM - COMMENTATOR TERMINAL
Bespoke: The Commentator Terminal
Each oratis COM3 commentator terminal provides a workstation precisely tailored to the application. Up to three commentators can be connected to each terminal – either with headsets or in the traditional manner using separate microphones and headphones.
Each commentator is assigned a dedicated outgoing line and, if required, all three signals can be summed to a combined, mixed commentary.
oratis also supports cell-phone connectivity for mobile use. Extensive monitoring options allow for separate set-ups for each of the three commentators. Nevertheless, operation remains simple since each terminal can be preconfigured over the network using the oratis commentary management software.
Commentator terminal features include:
Integrated talkback function
Integrated foldback function
Three assignable stereo aux signals
Remote configuration over the network
Remote control (technical assistance) over the network
Failsafe fallback mix including cell-phone support
Ready for intercom-module installation
Phantom Plus for Noise Guard headsets (optional)
Toggle Commentary / Translator mode
BNC connectors for two LED gooseneck lamps
COMMENTARY SYSTEM - INTEGRATED SERVICES
The oratis COM 3 commentator terminal incorporates a Gigabit Ethernet switch offering two ports for connecting the terminal over Gigabit Ethernet lines (layer 2 protocol) to an oratis matrix frame. Therefore, redundancy is an intrinsic feature of the system.
The switch also offers four 100-Mbps downstream ports for other services. These ports can be used separately from the oratis system, for example, for displaying instructions from the intranet on a notebook computer, providing web access or for browsing videos at the commentator’s position. oratis COM 3 is a sturdy yet svelte console terminal. It can be powered from an AC outlet or alternatively from a 12V source such as a camera battery. Each oratis COM 3 can also be fitted with an intercom module. Since headphones and a microphone are already present, a simple keypad is sufficient for target selection. DELEC modules and third-party components alike can be used.
COMMENTARY SYSTEM - ADDED VALUE
A Value-added Platform: oratis is the answer to many questions
oratis is more than just a commentary system – it is a universal intercom platform. The product range includes innovative network enabled intercom subscriber panels. These connect to intercom matrix cards, providing access to the entire network. Intercom systems can be built to include up to 4,096 ports, which can all be used simultaneously. The system supports large-scale campus or even country-wide installations with consistent, integrated intercom technology.
The high quality 24 Bit, 48 kHz audio (with internal 32 Bit processing) enables oratis to be used to distribute broadcast signals. This includes not only transparent routing but even the generation and processing of such signals.
Digital audio cards supporting the AES3 or MADI formats are available for transparent routing of studio signals (including Dolby-E signals). Alternatively, the signals can be fed directly to an oratis subscriber panel over an AES3 port; this is useful when using external sources physically located near to a subscriber panel.
The open system architecture and excellent audio quality make oratis a networked, distributed, premium quality audio-routing system with minimal cabling requirements.
COMMENTARY SOLUTION - AUDIO MATRIX
The Audio Matrix: Networking Without Frontiers
The product range includes oratis matrix frames of various sizes. Up to 15 oratis cards per 4-U matrix frame is achievable. Thus, oratis systems are the first choice whenever every inch counts – for example, in an OB truck.
Each matrix frame holds up twelve oratis IF LAN cards, each connecting one commentator terminal. The IF LAN cards can be combined with audio interface and intercom cards and can be supplemented with GPI interfaces used for controlling external devices.
oratis matrix frames can include a line-ident memory used for loop-playing up to 24 idents. This enables the various stations live studio lines to be identified uniquely. As soon as the commentator goes on-air, the line ident is automatically muted.
Studio-standard audio quality – 24 Bit, 48 kHz
32 Bit TDM bus for up to 256 signals
Fully redundant clock distribution
Hot-swap-enabled plug-in cards, matrix frames, and power supplies
External Wordclock input
Integrated line-ident memory (optional)
Integrated Support for SNMP messages (Simple Network Management Protocol)
oratis Matrix Frames Overview
COMMENTARY SYSTEM - LAN INTERFACE
Power behind the throne: oratis IF LAN
The oratis COM 3 commentator terminal can be used as a stand-alone unit. However, its true power becomes apparent when used in conjunction with an oratis matrix frame. Within the matrix frame an IF LAN card acts as a bridge interconnecting two worlds, conventional audio and the oratis network. While providing access to all audio signals on the matrix internal TDM bus, the IF LAN card connects the commentator terminal over redundant Gigabit Ethernet ports to the matrix frame.
The oratis IF LAN also provides a number of convenient functions including computation of a commentator monitor mix, interfaces to intercom systems, the implementation of foldback and talkback features and more.
The built-in Ethernet switch offers four tunnelled 100-Mbps channels to feed other services to the commentator’s position. This can significantly reduce on-site cabling costs.
Benefits of the oratis IF LAN includes:
Connectivity to all audio sources and destinations
Connection over managed Gigabit Ethernet lines
Supports four tunnelled Ethernet lines
Connection to talkback and foldback
Compatible with oratis audio and intercom cards
Integrates third-party components
Broadcast-quality audio output
FPGA: Flexible Signal Pathways
In all new oratis boards, Field Programmable Gate Arrays, (FPGAs), replace conventional signal paths. Instead of designing the signal pathway with copper connections in several layers on a circuit board, the logic modules of the FPGAs calculate the required signal path. The big advantage: Changes can be implemented quickly and at low cost by simply re-programming the software. Expensive and time-consuming design of complex new circuit boards can be avoided.
Thanks to this technology you can be sure that the oratis system can always match future requirements! Internally an FPGA chip is based on parallel processing and can compute many channels simultaneously. This also offers the advantage of further increasing the packing density. The high speed processing with constant and short computation time is also very beneficial. For these reasons, FPGAs are already established as the standard in other hi-tech markets such as telecommunications and the Internet.
COMMENTARY SYSTEM - CONTROL SOFTWARE
Well Matched: Central software-based configuration, support and servicing
oratis Commentary systems of any size can be handled in a simple and clear way using oratis VCMS, short for Venue Configuration and Monitoring Software. VCMS is the perfect tool for configuring, remote-servicing and remote-controlling commentator terminals.
The key to ease of use is the unlimited number of presets that the administrator can create and assign to COM 3 units. These presets store the basic system settings from the routing of microphones to outgoing circuits including phantom-power status and the monitoring setup.
Broadcast signal monitoring is another VCMS function. An expanded scale metering window or a reduced mixer view can be selected, enabling the levels of all outgoing signals to be checked and adjusted at a central position. Thus the signals of each of the twelve COM 3 units, which may be connected to a single matrix frame, can be monitored.VCMS can also be used to remote control the COM 3 terminals partially or fully. Whatever the application, oratis VCMS lightens the commentators workload appreciably during hectic broadcast operation.
Benefits of oratis VCMS:
Configuration of all commentator-terminal parameters
Store any number of presets and projects
Accurate monitoring of outgoing signal levels
Flexible adjustment and full remote control of connected commentator terminals
