1. EVS Software

1.1 INTRODUCTION

The EVS software is used for configuration and maintenance operations. It is also used to select which application to run, since EVS disk recorders have the ability to run various dedicated applications (Video Server, Slow Motion…).

When turning on the EVS mainframe, the first step is the PC boot sequence, followed by the boot of the video I/O boards, and finally the EVS software is started.

If a default application has been previously selected, this application will start automatically after a few seconds if no key is hit.

If a default application has not been defined or if the space bar is hit, the system will remain in the EVS main menu (see snapshot on next page) and wait for the operator's next command.

Dolby Digital or Dolby 5.1 or AC-3, is an audio coding system containing up to 6

discrete channels of sound, with 5 channels for normal-range speakers (20 Hz -

20,000 Hz) (Right Front, Center, Left Front, Right Rear and Left Rear) and one channel (20 Hz – 120 Hz) for the LFE, or subwoofer.

Dolby E is a professional coding system optimized for the distribution of surround and multichannel audio through two-channel postproduction and broadcasting infrastructures, or for recording surround audio on two audio tracks of conventional digital video tapes, video servers, communication links, switchers, and routers.

Case 1: The 5.1 audio signal is carried on 6 discrete PCM audio channels

• Available on an XTnano in all configurations

• The audio can be analog, digital or embedded depending on the configuration

• In AES audio, if the audio is correctly genlocked to the video, the sample rate converter can be switched off.

Case 2: The 5.1 audio signal is coded in the two-channel Dolby E standard

• Dolby E over AES/EBU links o

Set the configuration of the pair of channels carrying the Dolby E signal to

“DY” in the AVCFG. This has two effects :

 It disables the sample rate converter on the input channels

 It forces all transitions to a hard cut.

If the sample rate converter is activated and the audio configuration is a mix between PCM audio over AES and Dolby E over AES, the sample rate converter will only be applied to the PCM over AES signal.

• Dolby E Embedded in the SDI/HD SDI stream o

Set the configuration of the pair of channels carrying the Dolby E signal to

“EY” in the AVCFG. This will force the transition to a hard cut. o

The sample rate converter parameter does not apply to embedded audio.

The Dolby E transitions will be correct as long as: o the configuration is correct o the AES stream containing Dolby E is correctly synchronized with the video

Dolby E transitions will not be correct (2 frames of mute at the transitions) if the

AVCFG is set to E instead of EY or D instead of DY.

Audio effects (scrub, slow motion) are not possible in Dolby E. If they are used anyway, the audio will be muted.

With the 3D feature, two physical cameras will record the same scene with a slightly different angle to mimic the angle difference between the human eyes.

The 3D feature can be used on EVS servers fitted with V3Xnano boards. It is allowed through the code 23. It can be activated in the Channels Configuration

screen via the 3D option. See also the section ‘3D’, on page 10.

A dual-link interface, that is to say two physical channels (recorders or players) seen by the EVS server as a logical channel, is required to use this standard. For each pair of physical channels, only one logical channel is assigned in the

Channels Configuration. Such configurations require the record and playout on synchronous channels.

Note:

The dynamic bitrate management system modifies compression tables for each recorded field to keep the bitrate of the encoded stream as close as possible to the target. A higher bitrate means better picture quality and less storage capacity but a higher bandwidth is required.

NTERPOLATION

Possible values: on or off

This parameter enables or disables the interpolation processes. Select ‘off’ to disable the interpolation process, or ‘on’ to enable the interpolation process selected by the 'Four lines interpolation' parameter. An interpolation process is aimed at reducing the vertical jitter of the pictures that is present during slowmotion replays.

This vertical jitter is actually caused by a violation of the frame parity when playing back the pictures at less than 100 % speed.

20



Issue

10.05.A

The process consists in re-building new frames to produce a more transparent result. These frames have to be interpolated - that is calculated by making suitably weighted averages of adjacent lines. There are 2 interpolation modes: the

2-line interpolator and the 4-line interpolator. The disadvantage of this method is that it reduces the vertical resolution. This is particularly true with the 4-line interpolator.

The user can choose between 3 modes:

no interpolation: maximize the vertical bandwidth of the picture but a vertical jitter appears in “SloMo”. [set 'Vertical Interpolator' to ‘off’, whatever the value of

'Four Lines Interpolation']

2-line interpolator: reduce the vertical jitter but the vertical bandwidth is reduced. [set 'Four Lines Interpolation' to ‘off’ and 'Vertical Interpolator' to ‘on’]

4-line interpolator: the picture is perfectly steady but the vertical bandwidth is even more reduced. [set both 'Four Lines Interpolation' and 'Vertical Interpolator' to ‘on’]

Note:

All VTRs use interpolation in PLAY VAR mode.

When a disk is disconnected, it is orange and the RAID status section displays the percentage rebuilt at the position of the RAID number. When a disk is disconnected but new media is still being recorded on the disk array, this number will decrease until the disk is replaced and the rebuild process starts. The rebuild is complete when this number reaches 100%.

ROCESS

The XTnano server is capable of performing a rebuild process of the SCSI RAID.

This process can happen either while the Multicam application is not running

(offline process – rebuild is faster) or while the Multicam application is running

(online process – rebuild is slower).

Disconnection process

As explained in the previous section, the software will disconnect a disk that does not behave as expected.

Two options are available for the operator:

• Replace the disconnected disk and restart the server o

Start the Multicam application. The rebuild process will start automatically. o

Start a hardware check from the EVS menu and launch the rebuild. The process starts offline. The operator can wait for the rebuild to be completed or cancel it (that is to say postpone it) and start the Multicam application, in which case the rebuild carries on in online mode.

• The operator can also force the disk to be reconnected by starting the rebuild process in the hardware check. The process starts offline. The operator can wait for the rebuild to be completed or cancel it and start the Multicam application, in which case the rebuild carries on in online mode.

Maximum duration for on-line rebuild with SCSI disks:



• 5x300GB : 66h

• 10x300GB : 133h

• 15x300GB : 200h

Off-line rebuild time with SCSI disks takes about 6h for 5x300GB disks.

Issue

10.05.A

Note

If errors are detected during the rebuild process, a message appears after the rebuild is complete to warn the operator, and the raid is not considered as properly rebuilt. In this state, the system will keep working on 4 disks (SCSI disks or ‘4+1’ SAS disks configuration) or on 5 disks

(‘5+1’ SAS disks configuration). If you want to run on 5, or 6, disks again, you can try replacing the disk again and perform another rebuild, or clear all clips.

If you don’t need to retrieve the clips or the record trains, you don’t need to rebuild the RAID. In this case, select the “Clear All Clips” answer when the message with this option appears in the Hardware Check.

If you don’t rebuild the RAID array or if you don’t clear clips, the XS will keep running on 4, or 5, disks only, and you will see a warning message appearing every time you start or close the Multicam application. Normal operation can be achieved on 4, or 5, disks, but then, if another disk fails, the system will hang and all video and audio data will be definitely lost.

Important

By default, the online rebuild process takes up 10% of the disk bandwidth. If you want to change this, contact EVS support.

R

ETRIEVING

L

OGS

If you suspect that the drive disconnection in operation was not due to a severe disk failure, but perhaps to the server being too prompt to disconnect a drive, you must run a hardware check immediately after ending the session during which the disk was disconnected.

Don’t rebuild the RAID, but press simultaneously the ALT+L keys to generate the log file C:\LSMCE\DATA\LOG\SCSI.LOG, and send this file to EVS for detailed analysis. Note that this procedure is only valid if the drive is disconnected during operation, not for a drive being disconnected when booting the system.

2.3 READING THE CONFIGURATION FILE

After the disk initialization sequence, the system reads the configuration file stored on the disk. This file contains the parameters that guarantee the coherence of main parameters of the system from session to session. Those parameters are: diskBlockSize and operationalDiskSize.

The message "Reading configuration file… please wait" is displayed during process.

If the Configuration File is Found on Disks

The parameters are displayed:

Configuration of user block size xxx kBytes on disks yyy kBytes nbr of blocks aaa bbb

This table shows the parameters stored on the system ('on disks' column) and the ones from the EVS advanced parameters ('of user' column).

The values from both columns must be identical to use properly the system. If not, the system displays a warning message:

"A parameter incoherence has been detected" "Would you l i k e t o f o r m a t t h e s y s t e m

".

Answer ‘Yes' to format the A/V data saved on disks.

Answer 'No' to go back to EVS main menu.

Important:

If you answer ‘Yes’ and decide to format the system, all clips will be cleared. This operation is instantaneous.

If the Configuration File is not Found

A warning message appears:

"Your system is not formatted" "Would you like to f o r m a t t h e s y s t e m ?

".

Answer ‘Yes’ to format the A/V data saved on disks.

Answer ‘No’ to go back to EVS main menu.

If Errors Occur While Reading the Configuration File

The following message appears:

"Error reading configuration file – status = [Err]".

The type of error [Err] can be:

1. Block error A disk error occurred while loading the configuration file to disks. In this case, the disks have to be replaced by new ones.

2. Cache overflow error No more memory blocks are available from the memory cache.

3. Checksum error This error might occur when a disk has been replaced but the data of this disk is not restored.

For solving the problem, start the Rebuild data process.

4. Signature error The signature of the configuration file is modified or the file format is modified and then the file is not compatible with the microcode. In this case, select the Format command to correct the error.

If the loading duration of the configuration file is too long, a time-out error message appears:

"READ CONFIGURATION ERROR: TIMED OUT – state = [ST]".

In this case, reset the system and start again the application.

45

Issue

10.05.A



2.4 FORMATTING THE CONFIGURATION FILE

If the operator answers 'Yes' to the message "Would you like to format the system", the system generates a new configuration file on disks. The following message appears:

F o r m a t : c r e a t i n g a n e w c o n f i g u r a t i o n f i l e . b l k s i z e = n u m b e r o f b l o c s = x x x k B y t e s a a a

F o r m a t t i n g … p l e a s e w a i t .

If an error occurs, the message is displayed: "FORMAT ERROR: TIMED OUT – state = [ST]". In this case, reset the system and start again the application.

When format is completed successfully, the message "Format completed" is displayed and the system read the configuration file to be sure everything is in order.

Important:

If you answer ‘Yes’ and decide to format the system, all clips will be cleared. This operation is instantaneous.

2.5 INITIALIZING THE MICROCODE

The final step is the initialization of the microcode.

If the first line of the application is flashing with the message "Disk #x has been disconnected in operation", the system will display the message: "Disk to be disconnected: x". The system will work on 4 disks. Raid function is turned off.

The message "Init board: nb blocks of size kBytes. Audio:aud DiskUse:use%" is displayed. where nb size aud use is the number of blocks used on the system is the size in kBytes of a block on a disk is ON/OFF is the operationalDiskSize in %

If the system must load tables (no clear clips done in EVS main menu), the message "Loading tables …" will appear.

When the initialization is complete, the system displays the message "HCTX board initialized" and the system is ready. If an error occurs, the message "ERROR

(0xErr): HCTX board not correctly initialized" is displayed. The error (Err) are detailed in the following section.

Possible Errors

If an error is detected while loading tables, the following message is displayed: "

LOAD <TAB>LE ERROR – state = [St]" where ‘St’ can be:

1. Block error

2. Cache overflow error No more blocks available in cache. Algorithm problem. Contact EVS.

3. Checksum error

A disk error occurred while loading the table on hard disks. Maybe a disk failure. Replace disks.

This can occur if a disk has been replaced and data not rebuilt on it. Rebuild data on the disk to clear the message. If no disk has been replaced, try to re-start the server to clear the error message. If it does not resolve it after a few restart, a clear clip will be necessary.

4. Signature error The signature on the table file is not found in the header file. Try to re-start the server to clear the error message. If it does not resolve it after a few re-start, a clear clip will be necessary.

If the message "INIT ERROR: TIMED OUT – state = [St]" is displayed, it means the initialization is not complete. ‘St’ refers to a position in the code.

Note:

Never forget that to start Multicam, the bootwins must successfully initialize the microcode. In that case, the message "HCTX board initialized" is displayed. In all other error case, the boot sequence or initialization phase is cancelled and Multicam cannot be started.

2.6 DISK DATA RECOVERY

When Multicam is started, it sometimes happens that the application does not succeed in reading the data stored on the disks. However, the data is still available on the disks.

The EVS Disk Doctor has been developed to address this issue. This tool allows reconstructing the data (trains and clips) stored on the disks.

The tool scans each data block, identifies the recorder on which the data has been created and reconstructs the whole audio and video material.

The clips will also be recovered. However several overlapping clips will be recovered as one single long clip. This means that, in the schema below, the clips

CD, EF and GH will be recovered as one single long clip for which the IN point will be C and the OUT point will be H.
