1.- INTRODUCTION TO THE DIGITAL COMMENTARY SYSTEM

The AEQ broadcaster digital commentary system was specially designed for

radio and television reporting. Its flexibility makes it versatile enough to be

used in most remote program situations.

The digital commentary system engineering and operational design meets

international broadcasters standards and requirements, making it very easy to

operate while preserving a high level of maintainability. Unit configuration and

functional changes are by software, and are centralized in the venue technical

control room and therefore can be accomplished in a very short time. It is also

possible to carry out these functions, via a modem, from the Program Control

Ccenter (PCC) or similar, located in the International Broadcasting Center

(IBC).

The controls of each Commentary Unit (CU) are easily accessible and their

number has been reduced to a minimum in order to simplify “on air” operation.

Controls are clearly identified by color and visual displays.

Normally at each venue the signal comes to each Commentary Unit (CU)

through a Commentary Control Unit console (CCU) consisting of ten

commentary modules and one associated monitor unit. Both units are

interconnected by digital cable.

A Commentary Control Unit (CCU) is not used at smaller events, the

commentary unit operates as a STAND ALONE, sending and receiving signals

through the analog inputs and outputs, while keeping remote control

capabilities through the built-in serial port.

Both, the CU and the CCU, accepts in-system programming, which insures an

easy and inexpensive way of system upgrading up to the latest available

version.

1.1.- General description

Each Commentary System consists of ten commentator units (CU) connected

to a commentator console (CCU) through 4 pair data transmission STP or FTP

shielded cables used in data transmission.

The signals carried are as follows:

•Audio and control signals. There are two pairs for carrying digital data

related to audio feeds from commentators to the different output circuits, as

well as input signals to be monitored at the commentator’s side. Also

included are remote control signals, call signaling etc. The system includes

remote on field programming of the CU´s operational parameters (filtering,

AGC, compression etc.) and CU permanent software upgrade capabilities.

•Power supply. There is a dedicated pair for remote CU powering from the

CCU. CUs can also be powered locally, using a external DC power supply.

•Auxiliary line. The system offers one pair for direct auxiliary line connection,

thus avoiding supplementary wiring costs.

Each commentator position at the venues will be equipped with a commentator

unit that can be used by up to three commentators and a guest announcer

simultaneously. The position of the guest announcer can also be used to

playback a pre-recorded tape. The Commentator Units have been designed to

provide the commentators with their own commentary circuit and easy access

to all their coordination talkback circuits.

Through their microphone headset combination, commentators have access to

the following circuits:

Their own commentary output circuit (Program).

•A choice of incoming signals such as International sound TV from the venue,

International sound Radio from the venue, Public Address (P.A.) system,

cues from the venue mobile producer, a local cue, beeping signals and an

optional feed from another commentator or cue circuit.

•Two-way communications with the venue technician responsible for the

commentary system and with the IBC or their home studio.

1.2.- Commentary unit (CU)

The main function of this unit is to provide access to a combined microphone

headset for the broadcast of commentary or communication with a studio at the

IBC or the home country. The unit provides several operational possibilities,

which will vary in relation to the technical and operating criteria forecast for

each event, and in general are:

•The use of a microphone for commentary broadcast.

•Talkback from the producer at the IBC, studio or country to the commentator

at the venue.

•Commentator communication to the IBC studio or country producer.

•A return feed of the studio program output to the commentator.

•A feed which gives the results from the venue P.A. system.

•A two - way communications circuit between the commentator and the

operator at the Commentary Control Room (C.C.R.).

•Cue and venue information from the mobile producer.

•Cue information from additional organizations.

•Beeping signals of T’Back circuit.

•The option of disposing to listen the IS signal (preselected as the television

one or the radio one). from the competition site while broadcasting.

•The option of selecting a signal from the commentator GUIDE and an

auxiliary input (AUX) as a listening reference for the commentator to obtain

a data source for his commentaries.

All these functions are remotely controllable according to the technician’s

choice.

1.3.- Commentary Control Unit (CCU)

The Commentary Control Unit (CCU) is designed to control and monitor up to

ten commentator signals from the commentator units, as well as provide the

required remote powering.

Each of the ten modular control sections has:

•a level meter for the PRG output

•an output selector (oscillator, ID, program)

•a digital mixing section, where the selected IS can be added to the

commentary signals to get the PROG/IS feed. The IS signal can be

upgraded by the Digital Level Processor (DLP). Audio parameters

associated with the DLP are fully programmable under the control software.

•A section to enable the AUX and GUIDE signals to the commentator

•A section for the routing and aperture of CUE 1 and CUE 2 signals to the

commentator

•An individual remote control and configuration section for each of the four

CU channels (COM 1, COM 2, COM 3 and MIC/LINE)

•A section for switching and signaling talkback calls

•A line identification section (ID) for the program and coordination circuits.

The monitor unit provides the operator with access to all program and cue

circuits for listening via a built-in speaker or set of earphones. A precision dB

meter is provided to measure absolute levels on all circuits. The unit also has

intercommunication functionality with the program and coordination circuits.

The monitor allows access to the local talk back circuit or a connection to the

external 4 wire circuit.

The power supply section, located on the rear panel, consists of two

independent modules, giving the redundancy level required for these types of

events. Each one of the modules is thus able to fulfill the power requirements of

the CCU and the associated CUs. The power supply design includes advanced

techniques like power factor correction, input voltage autoranging, high

efficiency switching conversion, etc.

1.4.- Control software

The control software is a native 32 bits application, designed to run under

Windows 95 or Windows NT operating systems. It performs the following tasks:

•Can work in direct connection to a single CU, through the serial port, for

upgrading, setting audio parameters and real time remote controlling of the

unit.

•Can be used in a network configuration, carrying the full control of a given

number of CCUs and their associated CUs. Up to 32 CCUs (320 CUs) can

be controlled in this way.

•Performs real time supervision of the Commentary Control Network, using a

standard RS 485 (2 wire) interface. The required hardware is included in the

CCU as a standard option.

•Enables the user to define off-line configurations of the venue commentary

system, including audio and operational pre-settings. These pre-settings can

be downloaded to the real venue Commentary System. The setup time and

presetting tasks are dramatically reduced.
