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.

5.5.3 GENERAL PRINCIPLES ABOUT TC FIELDS ON THE GX SERVER

The following general principles are applicable to the various IN, OUT, TC fields and other fields displayed in the Edit GX Clip window and the GX Clips t ab:
• The IN and OUT points, and other TC-related fields defined as general, video
and audio settings for the GX clip refer to the timecodes defined on the raw materials. In other words, the reference timecode is always TC 00:00:00:00 of the raw material.
• The start timecode of the GX clip as it is played out and displayed to the
external controllers is always 00:00:00:00.
• All frames of a GX clip are played out. In other words, a GX clip that lasts 2
seconds will be played f rom TC 00:00:00:00 to TC 00: 00: 01:24 (for 50Hz clips) or TC 00:00:01:29 (for drop-frame 60Hz clips) if the corresponding raw material is played out from start to end.
• The GX clip length corresponds to the length of the longest raw material
(either audio or video), including possible loops.
5.5.4 G

ID8 FIELD
The Id8 field provides the 8-character ID presented to a VDCP client when it obtains a list of GX clips.
It is generated by incrementing by 1 the Id8 of the last file imported to the Raw Materials drive.
IDVAR
The IdVar field provides the variable length ID (up to 32 characters) presented to protocol clients t hat are able to view longer IDs.
It is generated based on the following pattern: [original file
name][first file number]_[final file number].[file extension]_[ID].
IN FIELD
The IN field gives the timecode, on the raw m aterials, at which t he GX clip should start. This is applied to both the video and audio tracks.
The reference timecode (00:00:00:00) corresponds to the beginning of the corresponding video and audio raw materials.
Example
If the IN field value is 00:00:00:10, this means both video and audio tracks of the GX clip will start playing 10 frames after the start of the raw material.

(VIDEO) OUT FIELD
The video OUT field gives the timecode, on the video raw material, at which the GX clip should end.
The reference timecode (00:00:00:00) corresponds to the beginning of the video raw material.
Example
In this example, the video raw material used for the GX clip is 2 seconds. The IN field is 00:00:00:10. The video OUT point defined for the GX clip is on TC 00:00:01:20 of the corresponding raw material.
This means the video track of the GX clip will be played out from TC 00:00:00:10 up to TC 00:00:01:20 of the video raw material.

(VIDEO) RAW DURATION FIELD
The video Raw Duration field gives the total duration of the video raw material used in t he GX clip. This field is not ed itable.
This d uration does not take into account t he following elements:
• the start timecode for the GX clip, d efi ned in the IN field
• the end timecode for the video track of the GX clip, defined with the Video
OUT point
• the loops defined (number of loops and loop length).
(VIDEO) LOOP FIELDS
Loop Check Box
The Loop check box needs to be ticked when the video track or part of it should be played out in loop.
When you t ick the check box, t wo additional f ields are displayed:
• The timecode at which the loop starts ( Loop Point).
• The num ber of times the loop is performed (Loop Recurrence).
Loop Point Field
The Loop Point field allows users to specify the timecode in the video raw material at which the loop will start. The loop will always be performed from that point to the Video OUT field.
The GX server will perform a nested loop if the loop point is set to anything other than the IN frame.
Loop Recurrence Field
The Loop Recurrence field allows users t o specify how many times the loop of the will be performed during playout.
When a loop recurrence is defined, the total duration of the GX clip specified below the video display is automatically adapted.
Note
You will find an example on loops in the section 5.5.9 ‘GX Clip Duration and Tim ecodes’, on pag e 57.

UDIO) OUT FIELD
The audio OUT field gives the timecode, on the audio raw material, at which the GX clip should end.
The reference timecode (00:00:00:00) corresponds to the beginning of the audio raw material.
Example
In this example, the audio raw material used for the GX clip is 3 seconds. The IN field is 00:00:00:10. The audio OUT point defined for the GX clip is on TC 00:00:02:10 of the corresponding raw material.
This means the audio track of the GX clip will be played out from TC 00:00:00:10 up to TC 00:00:02:09 of the audio r aw material.
In the example, the audio track defines the length of the GX clip since it is the longest trac k.

5.5.9 GX CLIP DURATION AND TIMECODES

PURPOSE
Based on an example, this section explains how:
• The protocol duration is calculated
• The timecodes of the GX clip are displayed, compared to the timecode of the
raw materials.
EXAMPLE
In the example, the follow ing settings have been defined:
• The video raw material is 2 s eco nds. T he audio raw material is 3 seconds
• The GX clip starts at TC 00:00:00:10 of the video and audio raw material (IN
field = 00:00:00:10).
• The GX clip stops at TC 00:00:01:20 of the corresponding video raw material
(OUT field = 00:00:01:20).
• A loop is defined on the video track from the loop point 00:00:01:10 to the
video OUT point of the GX clip. The loop should be played 4 times.

Last Frame of Video and Audio Tracks
The last frame of the video track c an be calculated as follows: 00:00:01:20 + 00:00:00:10*4 (4 loops) – 1f = 00:00:03:04. As an IN f ield is defined at 00:00:00:10, t he last frame of t he video track of the GX
Clip is 00:00:03:04 – 00:00:00: 10 = 00:00:02:24. The last frame of the audio t rack of the GX clip is 00:00:03:00 – 00:00:00:10 -1f =
00:00:02:14.
Durat ion of the Video and Audio Tracks
The dur ation of the vi d eo t ra ck in the G X clip can be c alculated as follows: (OUT-IN+1)+#loops*(OUT-Loop+1) = (00:00:01:20-00:00:00:10+1)+4*(00:00:01:20-00:00:01:10+1) = 00:00:01:11+(00:00:00:11)*4 = 00:00:01:11+00:00:01:19
00:00:03:05
Duration of the GX Clip
The GX c lip lengt h always has t he lengt h of the longest track:
• Without the 4 video loops, the GX clip would last 3 seconds since the audio
track would be longer than the video track.
• As 4 video loops have been defined, the video track is longer than the audio
track.
In this case, the duration of the video track, that is 00:00:03:05, is the longest one, henc e gives the length of the GX clip.
