System Components

Cerify accesses digital media from local storage, such as a local hard drive or DVD, as well as network storage, such as a Windows ﬁle server or FTP server.

A Cerify system can be set up in three basic ways:

The ﬁrst consists of a single self-contained unit which runs all the management and testing processes

of the system.

The second consists of a networked cluster of two or more units, which enables simultaneous

processing of a greater number of ﬁles. The networked cluster contains a single Supervisor and one

or more Media Test Units.

The third consists of a cluster of three or more units with high availability (HA) support. Cerify

Enterprise Cluster with high availability (also referred to as an HA cluster) is a Cerify cluster enabled

with support in the case of a Supervisor system failure.

Cerify Automated Video Content Veriﬁcation System User Manual 5

Getting Started Product Description

License Dongle

The license dongle must be plugged into the USB port on your computer to run the application. In a clustered system, Media Test Units acquire their licenses from the Supervisor.

In the case of an HA cluster, two identical license dongles are supplied. The two dongles need to be inserted in the USB ports of the primary and secondary supervisors. Media Test Units will acquire licenses from the active primary Supervisor.

The license dongle you received should look like one of the dongles shown below.

License dongle

It is possible to navigate the user interface and see previous results when no dongle is installed, but it is not possible to carry out new checks of digital media ﬁles. The license dongle controls:

The types of codecs and ﬁle formats that can be checked

The number of channels that can be used

For demo dongles, when the license will expire

Server conﬁguration (Supervisor, Secondary Supervisor or Media Test Unit, High Availability cluster or not, etc.)

NOTE. In a high availability (HA) cluster, if you unplug a dongle and plug in another dongle, or if the connected dongle is upgraded with a new v2c ﬁle, a restart of Cerify is necessary for the license dongle to work correctly.

When you install a new version of the Cerify software for a high availability (HA) cluster, both of the dongles connected to the primary and secondary Supervisors must be upgraded.

Getting Started Product Description

Networking

In a clustered conﬁguration, network interface on all of the units, including the Supervisor, secondary Supervisor (HA cluster only) and Media Test Units, should be connected to the local area network. This connection is used to access media ﬁles, to service Web clients, and to carry cluster control trafﬁc.

Software Components

Software components include:

A Web-based user interface, which allows users to create and control Jobs, and to view or report the results of these Jobs. This interface is accessed over the network by using a Web browser. All you need to know is the IP address of your unit.

Media test service, which performs media ﬁle veriﬁcationaccordingtotheruleschosenbytheuser.

A database, which provides robust storage of the system entities, including users, Jobs, and Job results.

An XML-based control and reporting API known as CeriTalk. CeriTalk allows interaction with Cerify from within other applications, making it possible to integrate Cerify with other content management, broadcast automation, and workﬂow systems.

A Web application server that provides access to the Web interface and runs the core services for the application.

A license server, which controls the types of ﬁles t hat can be veriﬁed.

The system tray icon and menu, which provides access to the Cerify Web-based user interface and allows the application to be started and stopped. The system tray is not available when Cerify is installed as a Windows service.

Cerify as a Standalone System

A standalone system is a single machine that combines the functions of a Supervisor unit and a Media Test Unit. The process that carries out the media ﬁle testing is known as the Media Test Client (MTC).

Cerify Enterprise Cluster

The Supervisor unit controls the cluster system. It hosts the database and the Web server, allowing multiple users to set up and view Jobs.

Cerify High Availability Enterprise Cluster

The Cerify high availability enterprise cluster (also referred to as an HA cluster) is a Cerify cluster enabled with support in the case of a Supervisor system failure. In an HA cluster, one of the member units of the cluster is conﬁgured as a backup to the Primary Supervisor and is called the Secondary Supervisor.

If Cerify on the Primary Supervisor goes down for any reason (for example, due to a machine crash), the Secondary Supervisor automatically takes over and manages the cluster. All other units (MTUs) now form aclusterwi the Secondary Supervisor and will be ready to take over when the current Supervisor goes down.

The Second and the MTUs in the cluster while performing the job of a Secondary Supervisor.

In an HA cl interface cards on the system. One will be used for the cluster function and the other for communication (Ceritalk/Web). Also, it is mandatory to use static IP addresses for all the units forming the HA cluster.

In an HA cluster, identical dongles must be connected to the Primary Supervisor and Secondary Supervisor. When starting an HA cluster, the cluster units should be started in the following order:

1. The Primary Supervisor should be started ﬁrst with one of the two HA dongles installed. At the time the Primary Supervisor is started, the system with the Secondary Supervisor installed should be up and have the matching HA dongle installed. Otherwise, the Primary Supervisor will not start.

2. The Secondary Supervisor should be started next.

3. The Media Test Units should be started one by one after both the Primary Supervisor and Secondary

Supervisor are started.

All of the PCs in the cluster should be able to route to each other. The Supervisor unit and the Secondary Supervisor unit (in the case of an HA cluster) each need to be given a network name that is recognized and resolved by all of the units in the cluster.

You should know the fully qualiﬁed name of the Supervisor unit and the Secondary Supervisor unit and provide these when the installer of the other units in the cluster asks for the names of the Supervisor and Secondary Supervisor units.

In the case of a normal cluster (non-HA cluster), if the Supervisor or Media Test Units have more than one network interfaces, it is better to bridge all the network interfaces together. For instructions on conﬁguring the network bridge, refer to Conﬁguring a Network Bridge

Synchronization between all the units in cluster must be maintained. For example, use an NTP server to synchronize the units in a cluster.

Getting Started Product Description

Clustering Scenarios Which may not Work

Clusters may not work in the following scenarios:

If the Supervisor, the Secondary Supervisor (in the case of an HA cluster), and the Media Test Unit are in different subnets wherein the switch blocks the multicast or UDP trafﬁc.

If any of Supervisor, Secondary Supervisor, or Media Test Unit systems has Windows ﬁrewall running, the Firewall may need some additional conﬁgurations for the cluster to work. Contact your Tektronix representative for more informationonhowtosetupthisconﬁguration.

If a Media Test Unit or Secondary Supervisor cannot resolve Supervisor host name.

In the case of an HA cluster, if the Supervisor can not resolve the host name of the Secondary

Supervisor and vice versa.

If the Supervisor does not have a host name or if the Supervisor has a host name with Japanese or Chinese characters.

If a network has another system with the same host name as the Supervisor (or Secondary Supervisor) system.

If the host name of the Supervisor (or Secondary Supervisor) changes after cluster installation.

If the http port on the Supervisor is conﬁgured to a different port number after cluster installation. In this case, the property cerify.supervisor.httpport in the cerifysystem.properties on the Media Test Units must be changed to the new port number.

If the http port on the Supervisor is conﬁgured differently than that of the Secondary Supervisor.

If the IP addresses of any units in the cluster change after the installation. In this case, the property cerify.jboss.bindaddress must to be changed to the current IP address.

In the case of a normal (non-HA) cluster, if the Supervisor has multiple network i nterfaces connected to the same network and if DNS/WINS are not conﬁgured properly, troubleshoot this problem by doing either of the following:

By adding an entry containing the Supervisor host name and the IP address used by Cerify on Supervisor in "hosts" ﬁle, which can be found in

C:\WINDOWS\system32\drivers\etc in all

the Media Test Units.

By bridging all the network interfaces together.

Clusters might not work correctly if there is momentary network outage in which case the clusters have to be restarted.

This section recommends hardware conﬁguration for some situations in which Cerify is typically used.

Cerify can be installed as either of the following two conﬁgurations on a given computer:

Single channel. A single channel installation is one that is licensed to test a single media ﬁle at a time. Such installations are normally performed on a PC or a laptop computer and are suitable for situations where a low throughput is sufﬁcient and performance is not critical.

Multichannel. A typical multichannel installation of Cerify tests 4-8 media ﬁles at a time on a single unit. Due to the high throughput and performance requirements that are expected from such installations, it is recommended that server class hardware and operating systems be used in such cases.

In addition to the throughput required, the hardware requirements also depend heavily on the mode of operation that will be used. Cerify can operate in two modes:

Streaming mode

In this mode, media ﬁles are read directly from the media server hosting the ﬁle and are not copied to the local hard disk of the Cerify system. This is the default mode of operation and is also the preferred one.

Copying mode

Media ﬁles are copied to the local hard disk of the Cerify system before processing can begin. By default, Cerify will not copy ﬁles to the local hard disk, but it is possible to force Cerify to operate in this mode.

The mode of operation that applies to your Cerify installation depends on the ﬁle formats you would like to test and other work ﬂow and connectivity related constraints that might apply to your situation. See the

Modes of Operation

The functional differences between these two modes of operation impact primarily on the disk space availability and disk conﬁguration requireme of disk space and high levels of concurrent read/write performance from the hard drives in order for best overall performance while the streaming mode can derive comparable overall performance with a lesser amount of disk space and lower read/write efﬁciency. Consequently, when possible, the streaming mode should be used in preference to copying mode.

(see page 294) for a detailed discussion on the factors that inﬂuence this.

nts. Speciﬁcally, the copying mode requires a greater amount

The general guidelines that should be followed when selecting hardware are:

Processor: 3 GHz

Cerify is capable of using as many processor cores as available for improved processing performance. While the minimum required conﬁguration is 2 cores per channel, for optimum performance, it is recommended to allocate between 4 and 6 processor cores per Cerify channel. It is also recommended that for best performance, you choose as much on-chip memory cache as possible.

NOTE. Cerif Intel based server platform.

Memory:

It is recommended to use a minimum of 4 GB of RAM per channel and an additional 4 GB for the operati memorythereforeis:4x4GB(perchannel)+4GB=20GB.WhentheexpectedloadinCerifyis likely to be largely composed of huge media ﬁles, more memory per channel may be necessary.

Hard disk drive: 100 GB x 3

For an e Windows and Cerify installation (including database) to achieve fault tolerance in case of disk failure. This logical drive should be at least 100 GB in size. For systems that are expected to support high levels of throughput, it is recommended that you have 500 GB of space on this logical drive.

The amount of additional storage you need depends on the mode of operation that applies to your installation, the average size of the ﬁles you will be processing and the number of channels you will be running.

y is optimized for Intel processor architectures, and therefore it is recommended to use an

ng system and the Cerify database. For optimum performance for 4 channels, the recommended

Streaming mode

Due to the minimal hard disk utilization when operating in the streaming mode, it is sufﬁcient to provide a single dedicated hard disk of 100 GB in size as temporary storage for Cerify.

Copying mode

The minimum hard disk space provided must be greater than the average ﬁle size being processed multiplied by the number of channels. It is recommended that the temporary storage be RAID-ed for better performance.

For help choosing the optimal number of hard disks for your installation and the best RAID levels to use, see Conﬁguring Your Cerify Installation for Best Performance

Network interface: 1 Gbit/s

You might use multiple network interfaces to improve available network bandwidth.

If your machine is not properly conﬁgured or you do not know the name o r IP address information, contact your system ad

Installation Considerations

The DPP Application requires CeriTalk’s IP and port n umber details. In the case of ENT cluster, it should be supervisor’s IP. In the case of HA cluster, it should be CeriTalk’s IP address, which is common for both supervisors.

If the port number of Cerify is changed (from the cerify.properties ﬁle), then the Cerify IP address and port number should be passed as the ﬁrst argument for “DPPApplication.exe” in the Sample “DPP Application” action template. For example, if port number 90 is used on 192.158.11.201,

hen 192.158.11.201:90 should be supplied as the ﬁrst argument.

It is recommended that the Cerify application be installed on a machine where it can be used as the sole running application. Cerify makes intensive use of both CPU and memory and will considerably degrade the performance of other running applications. Similarly, running other applications or services simultaneously will degrade the performance of Cerify and increase the time taken to process amediaﬁle.

Cerify relies on third-party software applications that are packaged and installed with it: JBoss and MySQL. If these applications are already used on the PC, you should remove them before attempting to install the Cerify.

The Cerify license server relies on Sentinel HASP (formerly Aladdin HASP SRM) drivers, which are installed and conﬁgured along with it. It is recommended that other applications that rely on HASP licenses not be used with Cerify on the same machine.

<Installation

The following lists the different situations for standalone installation:

When Cerify is started with no dongle connected, then (irrespective of whether a value has been speciﬁed in the “cerify.processorsperbox” property or not) the number of allowed channels is zero.

When Cerify is started with a perpetually licensed dongle and if the “cerify.processorsperbox” property is not set then the number of allowed channels is controlled by the dongle.

When Cerify is started with any valid dongle and a valid number of channels is speciﬁed for the “cerify.processorsperbox” property, then this value would be used if it is less than or equal to the number of channels controlled by the dongle. If the value is greater than the number of channels

ntrolled by the dongle then the number of channels controlled by the dongle takes precedence.

When Cerify is started with any valid dongle and the number of channels speciﬁed for the

cerify.processorsperbox” property is -1, then the number of allowed channels is controlled by the

When the Cerify system is to access media ﬁles from a Grass Valley Proﬁle or K2 server. In this case, the additional network interface should be connected to the control network that runs the Grass Valley AMP service. This enables Cerify to list the contents available on the Grass Valley servers. The ﬁrst network

Limitations with the Web User Interface

Windows style paths (E.g. C:\Temp\ﬁle.text) are now supported the user interface for creating MediaLocations and MediaSets. However, they should not be used in Action Templates, where it is still necessary to use ﬁle:// style ﬁle names.

Altering the URL or user credentials of a MediaLocation that is being used by one or more MediaSets may cause inconsistent behavior in the Web user interface. If this occurs, create a new MediaLocation andrecreatetheMediaSetsthatwereusingtheoldMediaLocation. Changingthepropertiesofa MediaLocation that is not yet being used by any MediaSets does not cause any problems.

When setting up Grass Valley MediaLocations, you must specify the username and password to use to access the Grass Valley server. The system no longer assumes the username "movie" when

When jobs are restored from b eing archived they will always have a stopped status. This avoids the

ored job cause unexpected processing if the relevant MediaSet has had media ﬁles added since the

rest job was archived; this would cause a previously complete job to resume processing. You can restart stopped jobs using the Resume action in the drop-down menu at the bottom of the jobs monitor page.

The use of "<", "?", "&", "#", "%", "+" and "\" characters within media ﬁle name (or name of the folder containing the media ﬁle) will prevent the media ﬁle from being added to a MediaSet. If this occurs, rename the ﬁle (or folder).

The Web user interface has been tested using Microsoft Internet Explorer versions 7 and above and Mozilla Firefox 3.0 and above.

When creating a MediaSet, the Web user interface ﬁle browser will respond slowly if the directory being listed contains many thousands of sub directories. This situation is typical when using Pinnacle servers. During this period, the Web browser will show the message Please Wait. However, in some situations the Web browser will also display a warning dialog message indicating that the page's JavaScript is responding slowly. The message may be safely ignored and the script should be allowed to continue to completion.

You can use action templates to copy and delete single media ﬁles after they have completed processing. For video servers that store assets using directories (for example, Pinnacle servers), or referenced formats (for example, Omneon Quick Time ﬁles), it is not possible to copy or delete the entire media clip asset with this mechanism.

Not all ﬁles that Cerify is able to process can b e played back using VLC. More details can be found in the "Enabling VLC playback" section of the user manual.

Before using the system, you must log in with your username and password credentials. These credentials will have been assigned by a user who has administrator access.

By default, the system is installed with a single predeﬁned user whose name and password are both set to admin. This user has administrator access. It is recommended that this password is changed the ﬁrst time the administrator logs into the system. Administrator access rights allow a user to modify system properties, and in particular to create and modify MediaLocations

Operating Basics Concepts

MediaLocations

A MediaLocation is a local or network ﬁle storage location from which the system can access media ﬁles. Typically, this would be a directory on the hard drive or a video server that provides FTP or Windows ﬁle share access. To create a MediaLocation, a user must supply its URL and the username and password required to access this URL. In addition, you must supply a unique name to be used within the system to identify the MediaLocation.

Only users with administrator access are able to create or modify MediaLocations.

Refer to Admin Page

MediaSets

A MediaSet is a collection of media ﬁles that you want to check.

A MediaSet can be a DropBox. A DropBox is a directory that is continually monitored for new media ﬁles. A MediaSet that is not a DropBox is simply a static collection of media ﬁles manually selected from one or more of the MediaLocations.

If a Job is associated with a DropBox, every ﬁle that appears in the DropBox over time will be processed.

For additional information, refer to MediaSets

Templates

To check a media ﬁle, you must deﬁne which checks should be applied when the ﬁle is tested. A Template is a collection of such checks chosen to perform speciﬁc tests that you require. The four types of Te

mplates are:

Container Templates, which apply to the transport/container layer of a media ﬁle

Video Templates, which apply to the digital video content of a media ﬁle

Audio Templates, which apply to the digital audio content of a media ﬁle

Action Templates, which specify actions to be performed as a result of processing a media ﬁle

You can create multiple Templates of the same type for different purposes. For example, you might create a "Movies" Template, which contains a set of rules appropriate for HD MPEG-2 content, and an "on-line content" Template, which contains a set of rules appropriate for lower resolution H.264/AVC content.

For additional information, refer to Templates

For example, it makes no sense to apply any container or audio checks to a media ﬁle that consists solely of a video elementary stream.

You can deﬁne multiple Proﬁles for different purposes. Following on from the previous example, you might create an "on-line content" Proﬁle, which speciﬁes a QuickTime Mov ﬁle wrapper in the container Template, H.264/AVC checks for the video Template, and AAC checks for the audio Template.

Operating Basics Concepts

Jobs

A Job is the term given to an individual testing p rocess that can be run by the system. Each Job can process multiple media ﬁlesorasinglemediaﬁle, depending on the requirements of the user. The set of ﬁles processed by a Job is deﬁned by its MediaSet.

By creating a Job, you request the checks deﬁnedbyaparticularProﬁle be applied to the ﬁles in a particular MediaSet. In addition, you must specify the name and priority of the Job. The system can queue multiple Jobs to be run, whereby each Job is scheduled to be processed according to its priority.

The system processes one media ﬁle at a time.

How long it takes to process a Job depends upon a number of factors:

The resolution of the video being processed (the larger the picture, the slower the processing)

Alerts

Operating Basics Concepts

Archiving

The system allows you to archive entities that are no longer required. MediaSets, Templates, Proﬁles, and Jobs can all be archived.

When an entity is archived, it remains present in the database, and can be recovered if necessary. Archived entities are inactive and usually hidden from view. Inactive entities cannot be used to construct new entities. So, for example, if a Job is archived before completion, it will not process any pending media ﬁles.

For additional information, refer to Active/Archive View Control

Control (see page 46).

Clustering

To increase processing throughput, units can be clustered. Each cluster consists of a single Supervisor unit and one or more Media Test Units.

In a clustered conﬁguration, the Supervisor unit hosts the database and the Web server. The Supervisor unit communicates with the rest of the local network, accessing media ﬁles and serving the Web user

ace. The Media Test Units are allocated media ﬁles to process by the Supervisor unit. The results of

interf this processing are stored by the Supervisor unit into a single database.

Growing File Support

Cerify supports the processing of growing ﬁle on FTP, SMB, a nd File protocols. Cerify can start processing the ﬁle as soon as the ﬁle copy is started. For more information refer to Growing Media Files

Alert Levels

Four different levels of alerts can be reported by Cerify according to the severity of the issue: fatal, error, warning, and info.

Fatal

A fatal ale rt occurs when it is not possible for the system to complete processing of a media ﬁle and the processing is terminated. This might be caused by something in the media ﬁle bitstream, such as a severe syntax error that makes that stream completely unintelligible or an option being present in the bitstream that is not as a license error, or failure to copy a media ﬁle off a video server.

Error

An error alert occurs where the media ﬁle fails a check speciﬁed by one of the Templates that the media is being checked against. Alerts raised by syntax checking will be given an error status if they have the potential to prevent correct decoding of the stream. An example of this is where an out of range value has been used in a bit stream.

Start and End Positions of Quality Alerts

The quality alerts ( video quality (see page 111) and audio quality (see page 131) ) are special in that they can apply to a range of video or audio. This is in contrast to most alerts, which have an instantaneous

ion. Because of this, quality alerts within Cerify contain the following additional information:

posit

The start position of the error condition

The location at which the error condition exceeded its permitted length

The end position of the error condition

Only one alert will be raised for a given error condition sequence, regardless of length.

Example: A rule is set up to disallow more than 5 seconds of black during video. A video clip has an unwanted sequence of 30 seconds of black beginning at 1m 20s. Cerify will generate a single video quality alert with the following information:

Start: 1m 20s - the start of the black sequence

Location: 1m 25s - the point at which 5 second limit was exceeded

nd: 1m 50s - the end of the black sequence

Frame View

The Frame View Page shows a larger thumbnail image of the Frame. This thumbnail is based upon a down sampled version of the full frame, using the top ﬁeld only for interlaced content, so in some cases the detected artifact may not be visible. Red rectangles highlight any areas of the frame that generated alerts.

The frame time is displayed in “HH:MM:SS:FF” format in the case of non-drop frame timecode and “HH:MM:SS;FF” format in the case of drop frame timecode.

Media Processing Limitations

Cerify can process many kinds of video media. Consider the following limitations before processing video ﬁles:

Some video servers (e.g. Omneon) put a lead-in at the start of a stream with a different VBV buffer size to the rest of the content in the stream. Cerify always reports the ﬁrst VBV buffer size it encounters, making it possible for the reported buffer size to not match the expected value for the stream.

Some AVC streams do not indicate a video frame rate. For these streams a frame rate check, if selected in the video template, will fail. Video template tests that can be checked over a user-speciﬁed length of time (e.g. black frame or blockiness checks) will calculate the length of time to check based upon the <number of frames> / 25; i.e. a frame rate of 25 frames per seconds is assumed. If this assumption is not correct the user should specify the length of check based upon number of frames rather than length of time.

Cerify does not support in-stream changing of frame size. Cerify will terminate processing of a ﬁle if the frame size changes.

Audio streams with varying sample rates/SBR information are not supported.

The system template "Omneon QT" can be used to process any type of ﬁle that ad Quick Time format containing atoms supported by Cerify (refer to Appendix B of the user manual for details). This includes ﬁles that have interleaved essence and those that refer to external essence ﬁles.

VC-1 streams that do not contain a header at the start of the ﬁle will not be decoded correctly.

When processing media ﬁles, you can limit the number of alerts so that processing will terminate after the limit is reached. In this situation, the reported length of stream - and any derived stream properties, for example, bit rate - will be calculated on the basis of the length of stream actually processed, and not the complete stream. Also, checks that depend on the end of stream being found such as a check for black frames at the end of the stream will not be carried out. An alert is raised that warns the user of this fact.

The ﬁle size of referenced / non-embedded wrapper formats (such as some Quick Time and MXF ﬁles) is reported as just the size of the wrapper ﬁle and not the sum of all the referenced ﬁles. Care should be taken when using stream properties or checks (e.g. bit rate) for the system template. Stream properties and checks for referenced audio or video content can still be reliably used.

The detection of poster frames and the execution of black frame tests are only supported for 8-bit video.

When running black frame tests and silence tests, there may be a conﬂict if "test during video" and "test at end" checks are used in combination. If the former is set to check black frames during video, while the latter test requires black frames at the end of the video, an alert will erroneously be raised during the end period due to the former check. No alerts are missed so this behavior is still fail-safe.

Detection of audio test tones during video is not supported. Detection of test tones at start and end of media playback is supported.

heres to the Apple

Test coverage of the MPEG-4 main proﬁle video codec is limited.

When the Loss of Chroma or Pillar-box tests are set-up to ignore more than two seconds at the end of the stream, it is possible for the system to raise an alert without a video/audio thumbnail associated with it. The alert itself is legitimate and should be considered valid.

In some cases, video ser vers do not report up front a size for the ﬁle being transferred to Cerify for testing. In such cases, Cerify has no way of sensibly reporting the progress since Cerify requires the ﬁle size to cal for the duration of processing. Eventually, when Cerify has stopped receiving ﬁle data from the server, it considers the ﬁle-end to have been reached and accordingly moves the progress percentage from 0% to 100%. This is typically seen when processing ﬁles from video servers like Grass Valley servers that dynamically create the ﬁle for processing on request and with servers like Nexio that maintain a virtual ﬁle system.

Apple ProRes and Generic QuickTime Video decoding functionality are not available on Windows XP 64 bit and Windows Server 2003 64 bit as the QuickTime Player is not supported on these platforms.

After installing QuickTime Player, it is recommended to restart the system before running Cerify.

Automatic reprocessing of ﬁles within a DropBox may not work as expected, if the video server does not supply the ﬁle properties like ﬁle size and last modiﬁed time correctly.

Automatic reprocessing of ﬁles is not supported for DropBox created using GVG protocol.

Automatic reprocessing of ﬁles based on ﬁle size will not work c orrectly if vqual.io.ftp.ﬁlesizeunknown property is set to true in cerify.properties.
