Overview
Welcome in the EVS range of products and thank you for using an EVS XT[2] server . We will do our best to satisfy your video production needs and we look forward to continuing working with you.
The EVS XT[2] series servers are full digital in PAL (625i), NTSC (525i), 720p,
1080i and 1080p standards. These multi-channel, disk-based video servers are ideal for a wide range of broadcast applications, from sports and live production to playout and transmission.
1.1
XT[2] HIGH-RESOLUTION SERVER
The XT[2] server is typically used as a high-resolution server with various third party controllers, applications and automation systems using industry-standard protocols such as Sony BVW75, VDCP, Odetics, DD35, IPDP, or EVS’ AVSP,
EditRec, Linx API. XT[2] series servers can also be controlled by EVS applications:
Live Slow Motion (LSM) for sports production, including replays, highlights editing, and analysis tools like Split Screen to compare 2 synchronized actions side by side, Target Tracking and Painting to highlight a particular detail or provide tactical explanations
IPDirector: a suite of Windows software applications designed to manage networked EVS video servers. Its applications make it possible to control multiple channels within the XNet network, as well as to log an event, to create and manage clips and play-lists with advanced functions, among others to extract clips from a VTR It also provides extensive database search features.

AirBox : a Windows GUI to manage clips and play-lists with various advanced functions like loop playback, conditional transitions, etc.
1.2
XT[2] PROXY SERVER
From Multicam V10.01, a low-resolution option can be set up to use the XT[2] server as a proxy server only. The Proxy servers can be run on large production events as the counterparts of the high-resolution servers. In this case, they need to be included in an XNet network distinct from the high-resolution XNet network.
The XT[2] proxy servers are used for browsing purposes and can be controlled by
IPDirector or EVS’ AVSP protocols.
1.3
UNPACKING
Upon receipt of the equipment examine packing for obvious signs of damage. If damaged, do not unpack and inform the carrier immediately. Check thanks to the included packing list if all the items are present and if they show any mechanical damage. If yes, report damage or the missing parts to EVS or their appropriate representative.

The target bitrate of the encoded video stream can be set by the user within the accepted range: 8 to 100Mbps for standard definition, 40 to 250Mbps for high definition with the exception of Apple ProRes, Avid DNxHD® and DVCPro codecs working with defined bitrates.
The default values are MJPEG 30Mbps for standard definition and MJPEG
100Mbps for high definition.
The code-protected codecs are solely available when the corresponding code is valid.
Up to Multicam 10.01, all codecs used in the EVS Video servers were encoding in
8-bit. From Multicam 10.03, it is possible to perform the encoding process in 8-bit or 10 bit and to write a 10-bit file on selected codecs.

EVS XT[2] servers feature a native implementation of the Avid DNxHD® and Apple
ProRes 422 high definition video codecs. This enables native audio and video file transfers in either direction between the EVS XT[2] servers, and Avid and Apple post-production tools in High Definition. This document explains the impact of using Avid DNxHD® and Apple ProRes codecs on XT[2] servers, on the XNet[2]
SDTI network and on the XFile[2] or XF[2] in terms of storage capacity, number of usable video channels and network transfers.
For details on how to setup a direct connection between an HD XT[2] server and an Avid or Apple server, please refer to the specific documents

Avid DNxHD® is standardized at specific bitrates according to 2 profiles:
1.
Standard profile: 120Mbps in “PAL” (50Hz) and 145Mbps in “NTSC” (59.94Hz)
2.
High Level profile: 185Mbps in “PAL” (50Hz) and 220Mbps in “NTSC” (59.94Hz)
Although Avid DNxHD® is standardized at the specific bitrates mentioned here above, Avid products can seamlessly read DNxHD® files and streams at other bitrates. DNxHD® pictures at other bitrates than those defined by the 2 official
Avid profiles can also be referred to as “VC-3” as defined in SMPTE 1019.
To allow users to determine the best balance between picture quality, storage capacity, number of video channels per server, and network speed, EVS XT[2] servers can generate Avid DNxHD® files and streams at any given bitrate between
20Mbps and 220Mbps. These files and streams should remain compatible with Avid production tools.

How to Read the Following Tables ?
1.
Video Bitrate: value set by the user in the advanced parameters window of the XT[2] server
2.
Fields/Block: number of video fields that can be stored in one disk block of
8MB, taking into account 8 audio tracks.
3.
Actual Bandwidth: this is the actual disk/network bandwidth that is required for the real time record or real time playback of one video stream and its associated audio tracks.
4.
Max. RT Channels: this is the maximum number of video channels (real time record or real time playback) that one XT[2] server can support for a given frame rate and bitrate. Since an XT[2] server can have a maximum of 6 local video channels, any value higher than 6 means that these additional real time access can be used over the XNet[2] SDTI network.
For mixed configuration with standard and super motion channels on the same server, the following rule must be used to ensure that the settings do not exceed the maximum bandwidth of the server : (nbr of standard channels x their actual bandwidth) + (nbr of super motion channels x their actual bandwidth) must be lower than or equal to 150 MB/s.
Example: Can I run an XT[2] server with 2 records (1 super motion + 1 standard) + 2 play (1 super motion + 1 standard) in Avid DNxHD® with a video bitrate of 100Mbps in “PAL” ?
Calculation: 1 standard rec/play at 100Mbps uses 13.3 MB/s ; 1 super motion record/play at 100Mbps uses 40.0 MB/s; 2 x 13.3 + 2 x 40.0 = 126.6 MB/s.
Conclusion : this configuration is supported.
5.
Network transfers: the maximum bandwidth over the XNet[2] SDTI network is approximately 110 MB/s. To determine the number of real time transfers that can occur simultaneously over the network, this number must be divided by the actual bandwidth given in the table for a selected bitrate.
Example: How many real time transfers can I do over an XNet[2] SDTI network
(set at 1485Mbps) if I work with Apple ProRes 422 at 145Mbps in “NTSC” ?
Calculation:
Maximum SDTI bandwidth / Actual Bandwidth = real time transfers:
110MB/s / 18.4MB/s = 6 real time transfers.
Note: This number is the maximum that the network connection can support.
Of course it is also necessary that the XT[2] where the material is stored has enough local disk bandwidth to feed the network accesses, on top of its own local channels (cfr point 4. Max. RT Channels)

The Video Raid uses striping process across 5 disk drives. The video and audio data is striped over the first 4 drives while the parity information is saved on the fifth drive. If one drive is damaged, the Video Raid can use the parity information to recover the missing information, so that operation can continue seamlessly without bandwidth loss.
For more information on online rebuild, refer to the section dedicated to this subject in the XT Technical Reference manual.
1.9.9
I
NTERPOLATION
The playing back of smooth slow motion pictures carries specific issues: since some fields must be repeated at regular interval to provide the video at the playback speed required by the operator, parity violation appears regularly on the output video signal. This issue is specific to interlaced formats (525i, 625i and
1080i) and does not concern progressive formats (720p and 1080p).
If
O
and
E
represent respectively the odd and even fields of a standard video signal (50/60 Hz), we have:
The original video signal:
O E O E O E O E O E O E O E O E
The output video signal at 50% speed:
O E E O O E E O O E E O O E E
The output video signal at 33% speed:
O O E E E O O O E E E O O O E
The output video signal at 25% speed :
O O O E E E E O O O O E E E E
Fields with parity violation are shown in bold, underlined letters. As it appears from the above table, whatever the playback speed (with the exception of the normal 100% playback speed), a number of fields violate the normal parity of the output signal. This parity violation induces a 1-line shift of the field, resulting in a vertical jitter of the picture. The jitter frequency depends upon the chosen playback speed.
To avoid this phenomenon and provide a stable output picture, EVS developed 2 types of line interpolator: 2-line and 4-line interpolators. The interpolation process

LINE

NTERPOLATOR
The 2-line interpolator actually generates a new field, when the original field is in parity violation. Each line of this new field is calculated by a weighted average of the 2 neighbouring lines. This process solves the problem of parity violation and vertical jitter, but the drawback is a reduction of the vertical resolution on the interpolated fields, that appear unfocused. Another by-side effect is the alternation of original fields (perfectly focused) and interpolated fields
(unfocused), resulting in a "pumping" video signal.
4-
LINE
I
NTERPOLATOR
The 4-line interpolator uses a more sophisticated calculation based on the 4 neighbouring lines. By using suitable coefficients for the weight of each line in the resulting calculation, we apply this interpolation to all fields. The final result is a permanently, slightly unfocused picture. The advantage is a stable output signal with no jitter and no "pumping", but the vertical bandwidth is even more reduced.
The interpolator is of course always disabled at 100% playback speed, because there is no parity violation.
EVS use the same techniques with the Super Slow Motion disk recorder, working with all models of Super Motion cameras (150/180 Hz). The only difference between the processing of Super Motion and normal scan (50/60 Hz) signals is that the interpolator is always disabled at 33% playback speed, because the Super
Motion signal does not cause parity violation at this particular speed.
Whatever the choice, the resulting picture is thus always a compromise between stability and resolution. With EVS systems, the operator always has got the choice between any of the 3 above described techniques: no interpolation, 2-line interpolation or 4-line interpolation. Even if the operator chooses to use the interpolation, this process will be automatically disabled when not necessary
(100% playback for 50/60 Hz signal, 33% and 100% playback for 150/180 Hz signal).
Note
All professional VTRs use line interpolation in PlayVar mode to avoid vertical jitters.
Default value is interpolator off for all configurations except SuperLSM configuration in which 4-line interpolator mode is enabled.

CONNECTING MULTIPLE EVS VIDEO
SERVERS ON XNET
The XNet network is composed by several EVS video servers all connected with a
75-Ohm coaxial cable (BNC).
The exchange between systems is operated through the SDTI interface at 540 or
1485 Mbps.
On XT[2] servers there are one pair of SDTI connectors: XNet[2] Non-Relay connectors that can be used at 540 or 1485 Mbps.
The SDTI loop is closed only when the Multicam software is started. It is therefore recommended to use XHub when using Non-Relay connectors to avoid network interruptions.
The XNet requires a network server dedicated to the management of the Database shared among all LSM-EVS video servers. This is assigned to one of the LSM-EVS servers on the network. The EVS server acting as the network server can of course be used for standard LSM/video server operation.

5.
Network Type must be set to “Server” on 1 EVS video server (and only 1 ) on the network. The others must be set to either “Master” (to share clips and view others’ clips) or “Client” (to share clips only).
6.
A different network number must be specified for each EVS video server that you want to connect to the network. If the same network number is assigned to
2 different systems, the second one will not be able to connect and a warning message will be displayed.
7.
All EVS video servers must be connected with a good quality BNC 75Ohm cable to form a closed loop. Connect the SDTI OUT connector of the first EVS video server to the SDTI IN connector of the second one, etc until the loop is closed by connecting the SDTI OUT connector of the last EVS video server to the SDTI IN connector of the first one. The SDTI loop must be closed at all times during network operation. If for any reason the loop is open, all network communication will be interrupted and all systems will automatically switch to stand alone mode. When the loop is closed again, network operation will resume automatically. This problem can be avoided or limited using EVS XHub
SDTI hub.
8.
The distance shown in the table below is the maximum cable length between two active EVS servers, or 2 SDTI reclockers, on an XNet SDTI network, using a single piece of cable between 2 servers or 2 reclockers. Intermediate connectors, patch panels, etc., might degrade these figures. Depending on the number of servers connected on the network, the location of the master server, the presence or not of an XHub SDTI hub, the actual maximum values may be higher than indicated. If longer distances between servers are required, SDTI to Fiber converters can be used, allowing distances over thousands of meters if necessary. EVS has validated the following SDI-Fibre converters:

ROUBLESHOOTING
1.
With the default settings, 10 real-time transfers can be achieved on the network with standard definition pictures in normal conditions, and 3 real-time transfers with super motion pictures. Copy of a clip between 2 servers on the network can be made up to 5 times faster than real time, depending on network load.
With high definition pictures, these numbers are reduced to 3-4 real-time transfers and copy clip 2 times faster than real time.
These performances are also limited by the disk bandwidth available from the
EVS video server where the clips are stored. If the EVS video server “owning” the clips is doing multiple playbacks at the same time, freezes can occur on the remote EVS video server using those clips. Priority levels have been implemented to maximize network bandwidth efficiency: PLAY requests have a higher priority than SEARCH/BROWSE requests, which in turn have a higher priority than COPY requests. Note that “Live” (E2E) mode on a remote record train has the same priority level as a SEARCH/BROWSE request.
2.
Note that when working at 1485Mbps or 540Mbps, only passive SDI routing equipment may be used. The use of active SDI equipment should be avoided, because they could cause additional line delays and prevent the proper operation of XNet.
3.
If the start-up of the network at a specific speed does not work properly and all machines are apparently configured properly and the Multicam is actually started on all of them, this can be due to the fact that the selected cables to connect all EVS video servers together are not suitable or too long to operate at such a speed. You can decrease the speed of the SDTI network on all machines and try working in this mode. The number of simultaneous real-time transfers you can achieve is of course reduced.
4.
While working at 1485 Mbps, if the connection cannot be established, please make sure that all equipments are set to the same speed and connected to the non-relay connectors. All equipments should be started if not connected to an
XHub.
5.
It is recommended to use XHub if the network speed is set to 1485 Mbps.
6.
Once the network has been established, if the system acting as the network server is disconnected or shut down, another system will automatically be assigned to act as a new network server. The switch is automatic. The next machine to be automatically assigned as new network server is the one with the highest serial number in the SDTI network.

The Gigabit connection makes it possible to transfer video and audio material from the XT servers to external systems via the TCP/IP network.
The external systems can be the following:
• A storage system or an archiving system, such as XStore or XF[2].
• A non-linear Editing system, such as Xedio, Apple Final Cut Pro or Avid.
However, the external systems cannot read the raw files coming from the XT[2] servers. For this reason, XTAccess is used as a “gateway” between the XT[2] and the IT world. It takes up the role of gateway used so far by XFile/XStream as it creates file formats compliant with external systems.
XT Access is directly connected to the XT[2] servers through the Gigabit network via an FTP client. It runs on an XP workstation and is mainly controlled by the external systems (no user interface) via XML files or other processes.
The Gigabit connection fulfill the following functions in relation with the XT[2] servers:
• Backup of clips from an XT[2] server
• Restore of clips to an XT[2] server
The sections below briefly present the backup and restore of clips through the
Gigabit connection. Please refer to the XTAccess technical manual for full information about the possible workflows with third-party systems.

Workflow (Restore via XML File)
1.
An external system (which can generate XML files for restoring clips, for example MediaXChange or IPDirector) sends an XML file to XTAccess to request the restore (copy) of clips from an archiving or backup system to a given XT server.
2.
XT Access processes the XML file: a.
It gets the clip file to restore from the external system. b.
It restores, i.e. copies, the clip on the XT server specified in the XML file.
Workflow (Restore via Folder Scan)
1.
Based on the parameters defined in XTAccess, this application scans specific folders on external backup or archiving systems.
2.
When a clip file has been completed written to the scanned folder, XTAccess creates a copy of the clip on the XT server specified in the XTAccess parameters.
The restored clip receives a new UmID and LSM ID: o
Multicam automatically assigns a UmID to the restored clip. o
A start LSM ID is specified in XTAccess and incremented as defined for each new clip that is restored in order to find an empty location on the XT server.
The restored clip contains the clip metadata.
3.
The restored clip is moved from the scanned folder to one of the following subfolders on the external archiving or backup system: o
\Restore.done\: folder where the files are moved to when they are successfully restored. o
\Restore.error\: folder where files are moved to when they failed to restore.

The HP Procurve 2510G-24 and Cisco Catalyst 2960G-24TC can be used for small setups where no inter-VLAN routing is needed.
On larger setups, both GbE ports of the XT[2] servers or/and several ports on the
XF[2] are often used to increase the bandwidth or to allow redundancy. Since both
GbE ports of an XT[2] server cannot be used on the same sub-network, virtual
LANs need to be created. To allow the transfer of packets between the virtual
LANs, layer 3 switches are required. You need to select a layer 3 switch that is able to route jumbo frames.
A switch of the Cisco Catalyst 3750E series should be used on larger setups as they support jumbo frames, allow traffic to be routed between different VLANs and provide stacking capabilities.

HP switches have a lifetime guarantee with next-business-day advance replacement with no additional contract purchase.
HP switches are not compatible with Cisco's proprietary protocols (ISL, PagP,
PVST, etc.) which could be a problem for integration in some legacy Cisco environment. However, such a case is quite unlikely to arise and most of the time workarounds can be found.
The stacking possibilities of the Cisco 3750E series permit to have fully active

REDUNDANT IPDP SERIAL LINK
The IPDirector communicates with the XT[2] server via one serial link. If that link fails, the XT[2] server can no longer be controlled by any IPDirector.
From Multicam version 10.01, a failover mechanism has been put into place. This mechanism will switch the IPDirector link from one port of an XT[2] server to another port on another XT[2] server.
To ensure the failover, the backup links between IPDirector workstations and the
XT[2] servers need to be physically cabled to a second RS422 port, as shown on the following schema:
42
The serial link redundancy will ensure that there is no single point of failure in the setup. However, you need to put into place a thoroughly thought through IPDP configuration for the SynchroDB to continue working correctly. This can be achieved, for example, by defining an IPDirector workstation in Network mode.

VIDEO AND REFERENCE BOARDS
3.2.1
COHX B
OARD
The COHX board is divided in 3 parts: COHX base (centre front and back), COD A module (front left), and COD B module (front right).
COD A and COD B modules are the actual CODEC modules, each of them being able to be configured by software either as an encoder (for a record channel) or as a decoder (for a play channel). There are 3 hardware versions of COD modules:
SD only, HD only, or HD/SD. They are clearly identified by the sticker at the front of the board.
There are 2 versions of the COHX base: one with genlock, one without genlock.
The genlock model can easily be identified by the presence of 3 quartz synthesizer at the back of the board, on the right-hand side, and by the presence of the GLK and PSU OK LEDs on either side of the DIN connector at the centre front of the board. Note that a COHX board with genlock must be installed as
COHX #1 in first position (slot 2) in an XT[2] system (6U or 4U). A COHX board with genlock can never be installed in any other slot, and thus cannot be used instead of COHX #2 or #3. Doing so will result in conflicting electrical signals inside the system.

An XT[2] server cannot work simultaneously with an internal RAID array
(MT5D) and an external RAID array (XT-HDX). When an XT[2] server is equipped with the XT-HDX external disk storage, the MT5D internal
RAID is replaced by the MT5D_LNK board. This replacement has to be done by EVS staff.

When starting from a clean disk array (after a “Clear Video Disks” from the EVS maintenance menu), the XT[2] server is recording first on
RAID #0 until this one is full, then on RAID #1 and finally on RAID #2.
It is therefore normal to see activity only on 5, 10 or 15 disks depending on how much material (clips and record trains) is stored on the server.

The function of the PC board is mainly the control of the Video hardware via the software and to interface the peripheral equipment (i.e. remote controller) with the
Video hardware.
Two types of MTPC boards can be used:
•

•
A 2 / A 4 with COMMEL HS870 motherboard and a new time code management module (with bootable USB)
In standard configuration the PC hardware is composed by:
• One mounting PC board, with serial ports, LTC reader and generator, is controlled by the motherboard.
• IDE System Hard disk: the IDE disk drive is used for storing the EVS software and the DOS operating system. Neither audio nor video data is saved on this disk. The capacity of this drive may vary depending on market availability, but the system partition is always set to 1GB. The remaining capacity of this drive is not used.
• 64/128MB SDRAM modified. The SDRAM used has been modified to suit the system requirements. Please contact EVS support for RAMs upgrade. Do not use standard PC RAM modules.

HPOL, VPOL and ENVS are used to configure the composite sync generator used in LSM TV mode (no effect if LSM is only used with a VGA monitor).
The HPOL jumper can be used to invert or not the VGA HS signal (Horizontal
Sync) to generate the composite output signal (TV mode)
The VPOL jumper can be used to invert or not the VGA VS signal (Vertical Sync) to generate the composite output signal (TV mode)
The ENVS jumper can be used to enable or not the presence of the VGA VS signal
(Vertical Sync) in the composite output signal (TV mode)
If the LSM TV mode is used, these jumpers must be set-up according to EVS recommendations, which depend on LSM software version and CPU board model/revision:
With MPTC board A2/A3 or A2/A4, set up the jumpers as follows:
• HPOL=On; VPOL=Off; ENVS=On
REMOTE RESET jumpers are available to designate the remote(s) from which the RESET command can be sent.
This command resets the whole system: PC and video hardware.
In standard configuration only Remote one (on RS422 port 1) is allowed to reset the system.
Important
This jumper should be removed if the device connected to the RS422 port is NOT an EVS controller. Maximum voltage on pin 5 of an RS422 port of the XT server should not exceed 5 Volt when the corresponding jumper is engaged. Applying a higher voltage on pin 5 when the corresponding jumper is engaged will result in permanent electronic damage to the board.
