1. Introduction
1.1 GX SERVER PRESENTATION
1.1.1 GENERAL DESCRIPTION
The GX server is a 1U HD/SD fill and key playout server.
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 original format, then transcoded into GX clips on
the GX server.
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 the import of original files, the creation and the playout of GX
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 local network connection.
1. Users configure the server parameters from the web interface on the 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:
oWeb interface on the client PC
oDVD drive on the GX server
oUSB 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
State Disk drive).
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 GX server communicate via a RS 422 link,
by means of a control protocol like VDCP.
Important
The use of the web interface and the transcode operations are not
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 non-
industrial 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.

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 the 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
Adequate ventilation is obviously required for optimum performance. 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.

The original sequences are imported and stored onto the Raw Materials drive
(HDD).
INPUT VIDEO SEQUENCES
The following static files with embedded alpha channels are supported in release
1.0 of the GX server:
•Combined fill & key Targa sequences, i.e. TGA files.
Uncompressed TGA files or RLE compressed TGA files are supported.
•Combined fill & key Tiff sequences, i.e. TIFF files.
Uncompressed TIFF files or LZW compressed TIFF files are supported.
The file formats that include several video frames in a single file are currently not
supported.

The supported input audio files are stereo WAV files of 16-bit depth, 48 KHz,
including from 2 to 16 channels.
2.3.2 GX CLIPS
The GX clips are created in the database. The A/V material is stored onto the GX
Clips drives (SSD):
•The internal video files are stored in internal uncompressed formats, in the
requested video standard.
•The internal audio files are in raw 24 bits samples (per channel) format. They
can contain up to 16 embedded audio channels.
2.3.3 SUPPORTED VIDEO STANDARDS
The fill & key GX clips must have been prepared in one of the video standards
described in the table below:
Num Common

Only online clips having the video standard selected in the configuration
are visible from the control device. In other words, i
f the GX is
configured in 720p59.94, you will not see online clips in 1080i50
standard from the control device
2.3.4 CONTROLLER
The following communication protocols between the GX server and the switcher
are supported for playout:
