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 two 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 three 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.

System Installation

This section provides details of hardware, software and user prerequisites for the system and instructions on performing the software installation.

Prerequisites

Hardware Prerequisites

Cerify is designed to be run on a variety of PC hardware. Consequently, the choice of hardware is determined by performance and throughput requirements for your installation.

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

Single Channel Installation. A single channel installation of Cerify 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

e for situations where a low throughput is sufﬁcient and performance is not critical.

suitabl

It is recommended that you use a computer that meets the following minimum requirements for such

lations:

instal

Processor speed: 2 GHz

Cerify is a CPU-intensive application. For better results, choose a dual core system with a clock speed of 3 GHz and as much on-chip memory cache a s possible.

Memory: 2 GB RAM

It is recommended to use a minimum of 1 GB to a maximum of 3 GB per channel and an additional 1 GB for the operating system and the application. For best performance on a single channel install, this would be:

1channelx3GB+1GB=4GB

Hard disk drive: 50 GB of free space

The amount of hard disk storage necessary depends on the average size of the ﬁles that you will be testing and the mode of operation of Cerify that applies to the ﬁle formats that you are testing. Refer to Modes of Operation they impact disk space requirements.

Getting Started System Installation

Multi-channel Enterprise Installation. A typical multi-channel 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 installation

In addition to the throughput required, the hardware requirements for such installations also depend heavily on th

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

s, it is recommended that server class hardware and operating systems be used in such cases.

e mode of operation that will be used.

of Operation

(see page 228) for a detailed discussion on the factors that inﬂuence this.

The functional differences between these two modes of operation impact primarily on the disk space

ability and disk conﬁguration requirements. Speciﬁcally, the copying mode requires a greater amount

avail 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.

For multi-channel installations, the general guidelines that should be followed when selecting hardware (the values given are the minimum recommended for a 4-channel installation) are:

Processor: 3 GHz

Ensure you have twice as many cores as the number of channels. For a 4-channel installation, this

means that you should have eight cores available. It is also recommended that for best performance,

you choose as much on-chip memory cache as possible.

NOTE. The ProRes decoder is capable of using as many processors as available to improve processing performance. If you are processing ProRes media ﬁles, having more processor cores than the recommended two per channel might improve performance.

Memory: 6 GB RAM

Recommend a minimum of 1 GB to a maximum of 3 GB per channel and an additional 1 GB to 4 GB

for the operating system and the Cerify database. For the best performance with 4 channels, this

would be:

4-channelsx3GB+4GB=16GB

Hard disk drive: 100 GB x 3

For an enterprise installation, Tektronix recommends using a RAID on which to place the MS Windows and Cerify installation (including database) to achieve fault tolerance in case of disk failure.

Software Installation

Before installing the Cerify application, your PC must be correctly connected to your local network. This allows:

The Cerify application to test the ﬁles that are available on other machines on the network.

Other m achines to interact with Cerify automatically (for example, using CeriTalk automation clients,

or copying of report ﬁles to network locations).

Multiple users to connect to the Cerify Web user interface from remote computers.

For the last two cases, you need to know the IP address or the network name of the machine that Cerify is installed on. Network settings on the PC are conﬁgured in the usual manner using Windows. If your machine is not properly conﬁgured or you do not know the name or IP address information, contact your system administrator.

Users

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

(see page 121) and MediaLocation Management (see page 122) for more information.

(see page 111).

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

28 Cerify Automated Video Content Veriﬁcation System User Manual

(see page 67).

Operating Basics Concepts

Proﬁles

AProﬁle gathers together a container, video, audio, and action Template, providing a complete set of checks that can be applied when you want to test one or more media ﬁles. Any of the component Templates can be omitted, depending on your requirements. 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.

Jobs

For additional information, refer to Proﬁles

A Job is the term given to an individual testing process 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 deﬁned by a particular Proﬁle 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

The system processes one media ﬁle at a time.

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

Jobs to be run, whereby each Job is scheduled to be processed according to its priority.

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

The video standard concerned (some standards, such as H.264/AVC, take more time to process)

The number of tests selected (performing all the video quality checks can be processor intensive, because it requires the analysis of every pixel in each frame of video)

The bit rate (in general, the higher the bit rate, the slower the processing)

(see page 64).

Hardware performance of the PC on which Cerify is installed

For additional information, refer to Jobs

(see page 55).

Alerts

Alerts announce any checks that fail as a Job executes. Each alert indicates the severity of the failure, as well as where and why the check failed. The system gathers alerts associated with a particular Job, so that you can access the results from the top level and easily navigate to the details, such as which individual frames have Alerts.

The system organizes and summarizes any alerts raised against a particular Job, so that, at the top level, a single processing result status can be assigned to the Job. To view more detailed information, you can drill down through the interface, revealing (for example) which individual frames have raised alerts.

Reports provide you with a way to query the system database and obtain information in a predeﬁned format. A Job report presents the results of a particular Job in tabular form.

For additional information, refer to Reports

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

Processing Result

The Processing Result page provides information on the alerts raised by a particular media ﬁle. This page also displays the stream information for the media ﬁle concerned. Stream information is grouped into three separate sections: Container Info, Video Info, and Audio Info. Where there are multiple audio tracks in the stream, all track information is displayed. You can select the extent of stream information that gets displayed on this page using the stream information display

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.

Info

The quality alerts ( video q uality (see page 84) and audio quality (see page 97) ) 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 position.

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

Transport Stream). This check is mandatory and cannot be disabled.

Trying to treat a container format wrongly, for example processing an MPEG-2 Transport Stream as MXF, will almost certainly lead to spurious alerts. Cerify will raise an alert and cease analysis immediately in the event of a mismatch between observed and expected container format.

Checks the syntax and integrity of the container layer; that is, the problems in the wrapper ﬁle, but not in the elementary streams.

NOTE. Cerify does not perform full syntax checks for container layers, and is limited to reporting

serious errors that prevent the correct interpretation of the stream. This check is mandatory and cannot be disabled.

Alerts may be suppressed individually by entering the alert ID into the text ﬁeld titled Suppress alert IDs. Note that fatal alerts can never be suppressed. Suppressed alerts will not count towards any of the

alert limits set by the Alert limit or Individual Alert limit.

This rule can be used to limit the number of container alerts raised. It is not possible to switch off this check; however the value can be set to a maximum of 10,000.

Clicking the "Terminate processing if limit is exceeded" checkbox causes ﬁle processing to stop if the alert limit is exceeded. In this case, certain stream properties that require the whole ﬁle to be processed (such as length of stream) are not reported. Similarly, end of stream test cases will not be executed. If the checkbox is not checked, processing will proceed to completion but any further container alerts will be suppressed and not shown. In either case, an alert will be raised, indicating that further alerts have been suppressed. If the alert limit has been exceeded, fatal alerts will still be displayed.

Note that the Individual Alert limit canbeusedtopreventtheresults being swamped by a particular container alert.

This rule can be used to limit the number of container alerts with the same ID number. This prevents the results being swamped by a particular container alert. It is not possible to switch off this check; however, the value can be set to a maximum of 10,000. This value should be kept lower than the Alert limit value, since the latter takes precedence.

Checks the size of the input ﬁle in bytes. For container layers that support external references (for example MXF and QuickTime ﬁles) this does not include the sizes of the external ﬁles.

Checks the stream play time, deﬁned as the maximum play time of all decoded audio and video streams.

This tests the bit rate for the stream, calculated as the ﬁle size divided by the play time, as deﬁned above.

Multiple sets

This tests the number of video elementary streams contained within the container layer.

This tests the number of audio elementary streams contained within the container layer.

Checks that the audio stream duration is longer than the video stream duration by a minimum amount but not by more than the maximum speciﬁed amount.

Checks the packet size used by the MPEG-2 Transport Stream. This can be 188, 192, 204, or 208 bytes. Packet size is deﬁned as the separation between sync_bytes in the MPEG-2 transport stream. This is a check on the separation of the ﬁrst pair of sync_bytes only. If the packet size varies later in the stream, it will be reported as a synchronization error.

This tests against some of the requirements of CableLabs Video-On-Demand Content Encoding Proﬁles Speciﬁcation (MD-SP-VOD-CEP-l01-040107). The checks are: that the transport stream contains a single Program only; that audio streams must have stream type equal to 0x81 (Dolby Digital); that video streams must have stream_type equal to 0x02 (MPEG-2); that an MPEG-2 video stream is on PID 0x1E1; that a Dolby Digital audio stream is on PID 0x1E2, and any other audio streams follow on consecutive PIDs; that the Program Clock Reference (PCR) occurs in PID 0x1E1 (the video stream).

Checks that the Program Map Table associated with the decoded video stream includes a PID with Closed Caption data. Such a PID must include a VBI_data_descriptor (as described in ETSI EN 301

775) containing a closed_captioning_data_ﬁeld() element.

Checks that the Program Map Table associated with the decoded video stream includes a PID with Teletext data. Such a PID must include a teletext_descriptor (as described in ETSI EN 301 468).

Subtitle data. Such a PID must include a subtitling_descriptor (as described in ETSI EN 301 468).

Checks the syntactic integrity of the ﬁrst subtitle/teletext PID found in the transport stream.

Checks that the number of languages for subtitles carried in the transport stream matches with the user speciﬁed value.

Checks that the decoded video stream was found on a speciﬁc PID or PIDs. Multiple PIDS can be speciﬁed using a comma-separated list, and/or PID ranges. For example, "128-130,481" checks that the video stream is on any of PIDs 128, 129, 130 or 481. Hexadecimal PID numbers can be given by using the '0x' preﬁx.

Checks that the decoded audio stream was found on a speciﬁc PID or PIDs. Multiple PIDS can be speciﬁed using a comma-separated list, and/or PID ranges. For example, "482-484,4098" checks that the video stream is on any of PIDs 482, 483, 484 or 4098. Hexadecimal PID numbers can be given by using the '0x' preﬁx.

If this rule used on a ﬁle which contains no audio stream, an alert will not be generated. To catch this case, use the "Number of audio streams" rule.

Checks that the decoded text stream (teletext or subtitle) was found on a speciﬁc PID or PIDs. Multiple PIDS can be speciﬁed using a comma-separated list and/or PID ranges. For example, “128-130,481” checks that the text stream is on any of PIDs 128, 129, 130, or 481. Hexadecimal PID numbers can be speciﬁed by using the “0x” preﬁx.

These checks enforce or prohibit a certain duration of black at the beginning and end of the sequence, or to prohibit periods of black in the middle. The Black level tolerance ﬁeld determines what luma level is considered to be black by the test. If the Black level tolerance is N, then any pixels in the bottom N % of the signal range are considered to be black. An N value of 0% corresponds to a luma value of 16 and 100% corresponds to a luma value of 235. The Ignore failures for up to...% of picture area parameter allows a percentage of the screen area to exceed the threshold yet for the frame to still be considered black. This is typically used to disregard small amounts of analog noise and/or channel logos.

This check can detect a sequence of repeated frames. The Maximum allowed duration parameter gives the length of a frozen sequence above which an alert will be generated. Sequences of frozen frames equal to or shorter than this duration will not lead to an alert. For example: entering "2 identical frames" will allow two consecutive identical frames to pass, but will generate an alert if three consecutive identical frames are encountered.

The Ignore monochromatic frames option allows frames which are predominantly a single color (such as black) to be ignored and so not cause freeze frame alerts.

Frames are considered "repeated" if every 16x16 block of luma samples differs by less than a given root mean square error from the corresponding block in a previous frame. The Frames differ at ...% or more of luma range parameter controls this sensitivity. If you are getting frozen frame alerts for sequences with signiﬁcant movement, lower this value. If frozen sequences are not leading to an alert being raised when you think they should, raise this value.

(if the chroma components of the decoded video fall to zero or nearly so). The Maximum allowed duration parameter gives the maximum number of video frames or seconds that are permitted to be monochrome before an alert is triggered. The parameter Ignore failures for ﬁrst...at start allows the test to skip over a certain amount at the beginning of the video stream, without generating alerts. Similarly, the Ignore failures for last...at end parameter skips over a given amount at the end. These parameters are typically used to skip over monochrome title and credit sequences. The Chroma level tolerance percentage gives the signal level below which the check will trigger an alert. 0% will alert on Cr and Cb values of 128, while 100% will alert on any value from 16 to 240. The Ignore failures for up to...% of picture area speciﬁes the amount of the picture area that may contain color information without causing the check to trigger an alert. These last two parameters are typically used to disregard small amounts of analog noise and/or channel logos.
