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.

Lite version

z Outputs unencrypted JPEG 2000 encoded video (encapsulated in DCPs) for playback on

the JMP 9600

JPEG 2000 Encoder • Introduction and Installation 2

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.

DCP output.

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.

JPEG 2000 Encoder • Introduction and Installation 3

Software Installation

The JPEG 2000 Encoder application requires Microsoft .NET Framework 3.5 SP1 in order to function. Ensure that your encoding computer is equipped with this version of .NET Framework before installing the JPEG 2000 Software Encoder.
