1. Introduction

1.1 GX SERVER PRESENTATION

1.1.1 GENERAL DESCRIPTION

The GX server is a 1U H D/SD f ill and key playout s erver. The source graphic and audio files can be imported from the built-in DVD drive,
via the USB or eSata ports on the GX server, or via an Ethernet connection to a PC. They will be imported in their orig inal format, then transcoded into GX clips on the GX s erver.
The GX clips can be published to an external control device through a standard protocol like VDCP, and be played back under the control of these protocols on 2 SDI outputs (key and fill).
The GX server allows the synchronized playout of uncompressed fill and key GX files, and embedded audio. The server is able to handle separate video nested loops, with user-defined loop points.

1.1.2 GENERAL ARCHITECTURE AND WORKFLOW

SCHEMA
The following schema provides an overview on the system architecture and general workflow for t he import of original files, the creat ion and the playout of G X clips on the GX server. The schema is described below.

DESCRIPTION
When the GX server is switched on, the users can control the GX server from a remote PC via a web-based application using a loc al network connection.
1. Users c onfigure the server param et ers from the web interface on t he client PC.
2. Users import the original files (fill and key, audio) to the Raw Materials drive (internal HDD drive) using one of the following methods:
o Web interface on the client PC o DVD drive on the GX server o USB or eSATA connectors on the GX server
3. Users associate the original files, define synchronization parameters, and upload them (switch them online) as GX clips onto the GX Clips drive (Solid St at e Dis k dr ive) .
The files are then ready for playout.
4. When users start the GX server from the web interface, the GX clips that correspond to the requested video standard are published to the switcher.
The operator can then select the requested GX clips and play them out using the switcher. The switcher and the G X server communicat e via a RS 422 link , by means of a control protocol like VDCP.
Important
The use of the web interface and the possible while the GX server is started.

2.2.5 SAFETY, COMPLIANCE, AND OPERATING CONDITIONS

CE MARKING
The CE marking is affixed to indicate compliance with the following directives:
• 89/336//EEC of 3 May 1989 on the approximation of the laws of the Members
States to electromagnetic compatibility.
• 73/23/EEC of 19 February 1973 on the harmonization of the laws of the
Members States relating to electrical equipment designed for use within certain voltage limits.
• 1999/5/EC of 9 March 1999 on radio equipment and telecommunications
terminal equipment and the mutual recognition of their conformity.
POWER SUPPLY
This equipment is equipped with AUTOSWITCH and hot-swappable power supply. Connection to supply: Pluggable equipment Type A (EN60950 §1.2.5): Equipment
which is intended for connection to the building power supply wiring via a non­industrial plug and socket-outlet or a non-industrial appliance coupler or both. Correct mains polarity must always be observed. Do not use reversible power plugs with this equipment.
Class of equipment: Class 1 equipment (EN60950 § 1.2.5): electric shock protection by basic insulation and protective earth.
Rated voltage: 100 to 240Vac (single phase) Rated frequen cy: 47-63 Hz Related Current: 6 A (100 to 120 Vac range) 3 A ( 220 to 240 Vac range) Input connector: CEE22/IEC 320 3-pin male receptacle
Important
The protective earth must be connected to the ground before powering up the unit.
ENVIRONMENTAL CONDITIONS

HOT-SWAPPABLE POWER SUPPLIES
Both power supplies are hot-swappable. The second power supply should be connected to mains to allow automatic power
switching to t he second power supply in the event that the first one fails.
GROUNDING
Ensure the disk recorder unit is properly grounded at all times to avoid electrical shock hazard.
VENTILATION & RACK MOUNTING
Adequat e ventilation is obviously required f or optimum perform ance. As a result of this consideration, ensure no other equipment is located close to the mainframe.
Important
• Remember that fans are used to air cool the equipment and protect
it from overheating.
• Do not block fans intakes during operations.

3.2 CABLING

The GX s erver has to be cabled as shown on the sc hema below to allow:
• Users to im port video sequences and aud io files and to create t he GX clips on
the s erver from the client PC.
• Operators to control the playout via the switcher.
Important
The GX server is connected to the protocol clients through the RS422 port. Once the GX clips are ready for playout, the GX server however needs to be manually started
established. For more information on starting the GX server, refer to the sections
3.3.2 ‘Switching on versus Starting the Server’, on page 13 and 4.2.5 ‘Starting t he GX server’, on page 19.

The schema below shows how the GX server needs to be cabled before switching it on. The table hereafter briefly describes the connections highlighted on the schema:
# Description
1. Connect the power supply t o mains.
Connect the second power s upply to allow automat ic power switching in case of failure.
2. Connect t he VDCP client to the RS422 port on the GX server.
3. Connect the GX server to the loc al area net work via one of the GigE ports.
This will allow users to connect remotely to the GX server via the GX web interface.
4.
Connect the KEY and FILL connectors to the perform the keying of the GX outputs.
5.
Connect the Genlock feed to the GLK connector to make sure the video signals from t he GX server are s ynchronized in your setup.
The mouse, keyboard and VGA connectors at the back of the server also allow users to d irectly connect to t he server, mainly to per form tests and c hecks.

3.3 INSTALLATION

3.3.1 GX SERVER INS TALLATION AND GHOST RESTORE

The EVS staff will perform the initial installation of the GX server before the server is d elivered.
When the server is installed, a g host image of the installed GX ser ver is created in the Restor e folder (R: drive).
If you need to restore the ghost, please contact EVS support.

3.3.2 SWITCHING ON VERSUS STARTING THE SERVER

When the server is properly cabled, you switc h it on using the power switch on the front panel. Switching on the s erver does not mean starting the server.
Once the server is switched on, you still need to start it to allow external controllers to connec t to the GX server and to access the GX clips for playout. For more information, refer to the section 4.2.5 ‘St art ing the GX server’, on page 19.
Before you can start the server, you need t o make sure that:
• The server is proper ly configured for t he external controllers to acc ess the GX
clips.
• The GX clips have been created on the GX server, and are online, ready for
playout.
All these steps are covered in the Installation and Operation sections.

4. GX Web Interface

4.1 CHAPTER O VERVIEW

A dedicated web application, called the ‘GX web application’, makes it possible create and prepare the GX clips from a remote PC. Then you can upload the GX clips on the GX server, and eventually start the GX server.
This chapter gives an overview on the user interface of the web application, and on the general workflow you will follow. It contains the following sections:
