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.

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.

It is possible to navigate the user interface and see previous results when no dongle is installed, but it is not

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.
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).

Clustering Scenarios Which may not Work
Clusters may not work in the following scenarios:
If the Supervisor and the Media Test Unit are in different subnets wherein the switch blocks the
multicast or UDP traffic.
If any of Supervisor or Media Test Unit systems has Windows firewall running.
If a Media Test Unit cannot resolve Supervisor host name.

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.

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
