Release notes

General notes

New f eatures

Dongle reprogramming

This software release includes the following new features:

Support for audio loudness correction and re-multiplexing of corrected audio

Complete Dolby E support

Support for LXF container format

Enhanced PDF reporting capability

Timecode analysis for H.264 and DV video

Analysis of SMPTE302M audio

Support for analysis of closed caption in H.264 video

Apple HLS ABR content testing support

MXF metadata tests

Addition and improvements of video quality tests

Dongles used with Cerify v7.1 or older need to be reprogrammed to be used
with version 7.2 or above. If such an older version of Cerify is being upgraded
to version 7.2 or above, then it is required that users send in their c2v files to
Tektronix to obtain a new corresponding v2c file before installing the upgrade.
This will allow users to program the dongle with the new v2c file before using
Cerify version 7.2 or above.

NOTE. All versions after v7.2 require an update of the license dongle prior to

being able to use the new version. Please make sure to update your Cerify license
dongle before installing v7.5 as your Cerify system will cease to operate on v7.5
with the older license dongle until you get the license dongle updated to v7.5.
Also note, all users with a valid Cerify Annual Software Maintenance contract are
eligible to receive the base features included in this version without any additional
cost. Licensing for the optional Audio Loudness Correction functionality is an
additional cost that is not covered by the Cerify Annual Software Maintenance.
Please call your Tektronix Sales representative if you wish to add Audio Loudness
Correction to your existing Cerify system.

To obtain the license updates needed by your Cerify system to use this new
version, send the c2v file of your Cerify dongle to the following address:
[e-mail].

Cerify demo dongles need to be updated to version 7.5 in order to use new features
such as audio loudness correction and LXF container support.

Users upgrading from older versions do not need to export and re-import the Cerify
database. The upgrade of the database is performed as part of the update install.

For Windows XP machines, loss of network connectivity to the primary NIC ­e.g. removal of network cable, switch failure or hibernation of the PC - a fter

affect Cerify installations on Windows Vista or Server 2008 SE. This problem
will also not be exhibited if the machine is not connected to the network when
the application is started, it only occurs when network connectivity is lost.

The Cerify 6.0 or later software requires the use of a HASP NetTime dongle.
It is not possible to use a HASP Net dongle (as used with Cerify 5.x and
earlier) without updating the dongle firmware. Green HASP Max dongles (as
used with CerifyLite) are no longer supported.

When multiple HASP license servers are available on the network, there is a
chance that the Cerify unit will try to retrieve its license from a wrong server

Tektronix representative for more information on how to do this.

It is possible for the license server to retain handles to license features
that were being used by a Cerify machine that has suddenly lost power or
otherwise failed. As a result of this the Cerify application will not be able
to obtain a license until the license server is restarted. This will only be a
problem when the license dongle is not on the Cerify machine, so in this
configuration we recommend that the lice ns e server machine is restarted when
the Cerify application is restarted.

If Cerify reports license failures after the dongle has been installed, it is
possible that firewall software is interfering with the license service. Please
ensure that port 1947 is open in any firewall software that is in use.

Release notes

Database

Web user interface

It is possible (

but unlikely) that a power failure could lead to database
corruption. Backup the Cerify database regularly (build this backup operation
into your operating procedures).

To speed up backup/restoration of large Cerify databases, it is recommended
that you use the file:// protocol to backup to/restore from a local folder on
the Cerify unit.

Due to a limitation of the MySQL database, which limits the size of a single
instruction to 1GB, it is possible in rare circumstances that Cerify fails to
create a backup of a database when this operation is attempted through the
Web UI. Contact Tektronix support if you encounter this issue.

The latest database backup file should alway

s be checked for integrity before
attempting a product upgrade to ensure that it can be successfully imported
into the system after the upgrade. A tool has been provided to do this. From a
command shell prompt change to the Cerify installation directory and use the
backup checker batch file. For example:

C:\Program Fi les\Tektronix\Cerify> BackupChecker.bat
file://c:/Temp/backup.sql

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 t his occurs, create a new MediaLocation and recreate the
MediaSets that were using the old MediaLocation. Changing the properties
of a 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 these fields are left blank.

When jobs are restored from being archived they will always have a stopped
status. This avoids the restored job cause unexpected processing if the
relevant MediaSet has had media files added since the 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 processing multiple files whose names are identical, even though their
paths may be different (e.g. from Pinnacle servers where all assets are named
'std' and are stored in folders named after an ID), using the copy action in the
action template will result in files being copied over the previous one with
the same name at the target location.

UNC notation is not supported in MediaLocation URLs. For example, paths
of the form \\machinename\dir are not considered valid.

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 adheres to the Apple Quick Time format containing atoms supported by
Cerify (refer to Appendix B of the user manual for details). This includes files
that have interleaved essenc e and those that refer to external essence files.

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 d erived 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
"testduringvideo"and"testatend"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 v ideo is not supported. Detection of test
tones at start and e nd of media playback is supported.

In some cases, video servers 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 calculate the
progress percentage. As a result, Cerify reports the file to be at 0% progress
for the duration of processing. Eventually, when Cerify has stopped receiving

typically seen when processing files from video servers like Grass Valley
