Introduction and Installation This section gives an overview of the guide and features of the Extron JPEG 2000 Encoder software. Installation is also described. Topics that are covered include: zz About this Guide zz About the JPEG 2000 Encoder zz System Requirements zz Software Installation About this Guide This guide provides detailed information about the JPEG 2000 Encoder software, including software installation and encoding procedure.
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.
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. • 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.
