About this Guide
This guide provides detailed information about the JPEG 2000 Encoder software, including
software installation and encoding procedure. In this guide, “J2KENC” refers to the
lite version of JPEG 2000 Encoder and “J2KENC-PRO” refers to the full version. Notes
distinguish where the two versions differ.
About the JPEG 2000 Encoder
The Extron JPEG 2000 Encoder is available in two versions on the disc that is shipped with
the JMP 9600 JPEG 2000 Media Player. These two versions are:
z JPEG 2000 Encoder “Lite” — Provided free of charge to all purchasers of the
JMP 9600. This version is the default when the JPEG 2000 Encoder software is first
installed on your encoding computer. The application has basic functionality powerful
enough for situations that require encoding short clips with a single audio (stereo) file.
z JPEG 2000 Encoder “Full” — When the license and activation key are received from
Extron, all functionality of the full version is enabled without further software installation
(the full version is loaded as part of the initial installation on the encoding computer but
is disabled until licensed).
The software runs on Microsoft® Windows® 7 or Windows XP operating systems and
allows you to prepare content for playback on the JMP 9600 without the need for external
encoding services. It constructs visually lossless MXF wrapped Digital Cinema Package (DCP)
files. The DCP includes video, audio, and other associated data encoded to comply with the
DCI (Digital Cinema Initiatives, LLC) requirements for unencrypted content. The DCPs that
are generated by the JPEG 2000 Encoder are subsequently transferred to the JMP 9600 for
playback.
JPEG 2000 Encoder • Introduction and Installation 1
Features
As the time required for encoding a DCP is directly proportional to the number of image
frames and the size of the associated audio files, the full version software is tailored to use
all of the processing power of the encoding computer (see “System Requirements”).
The application can run simultaneously on multiple computers, thereby functioning as an
“encoding array” to significantly increase throughput when processing DCPs. The difference
in processing speed between the two versions is considerable.
NOTES: • Using the lite version for encoding large video clips can take many hours or
days.
• The lite version supports only a single thread (computer processor core), even if
the computer is multi-threaded, and a single stereo audio input.

System Requirements
Ensure that the system hardware to be used meets or exceeds the minimum requirements
listed below. Encoding performance improves when a system more powerful than the
minimum listed here is incorporated.
NOTES: • The encoding computers must be network capable.
Minimum system requirements:
z Intel
z 2 GB RAM
z Windows XP SP3
z Microsoft .NET Framework 3.5 SP1
z 1 GB of available hard disk space on the system drive
®
Pentium® 4, 2.8 Ghz (1 core)
5 GB or more is recommended on the installation drive and 20 percent free space on the
media drive (see the note below) for encoding temporary files (this value depends on
encoder compression rate).
NOTE: The Media drive is the hard disk drive on the local computer reserved for
• It is recommended that the application be used on a computer with superior
processing capacity, speed, and memory to reduce encoding time since the
process can take hours (or days), depending on the length of the video.

z Typical encoding performance: 0.2 frames per second
Recommended system:
z Intel
z 4 GB RAM
z Windows 7 64-bit
z Microsoft .NET Framework 3.5 SP1
z 1 GB of available hard disk space on the system drive
®
Core™ i5, 3.4 Ghz (2 cores, 4 threads) or better
5 GB or more is recommended on the installation drive and 20 percent free space on the
media drive (see the note below) for encoding temporary files (this value depends on
encoder compression rate).
NOTE: The Media drive is the hard disk drive on the local computer reserved for
DCP output.
z Typical encoding performance: 6.0 frames per second
NOTE: It is recommended that a monitor supporting the encoded resolution and
frame rate be used. This is beneficial for production and quality control after
encoding.
