Extron Electronics JPEG 2000 Encoder - Manual (Page 32)

Encoding Across Multiple Computers (Remote Machines)
You can incorporate a number of computers on a network into an encoding array to greatly
expand the throughput of the encoding system. The time required to encode the quantity of
data is reduced. This is significant as JPEG 2000 files can be very large (terabytes).
NOTE: The same (fully licensed) version of the JPEG 2000 Encoder software must be
installed on each computer that makes up the array.
When used in an array, the software behaves as a dual-master system. During the encoding
process, specific computers within the array can be set to encode a different DCP while
the remaining computers continue (albeit with fewer processing cores available) encoding
the specified DCP. Each computer running the JPEG 2000 Encoder is visible by the other
computers in the system, thus status and availability is known by each computer. This allows
you to bring more or fewer computers online for an encoding task.
NOTES: • The source files (frames and audio) must be on a drive mapped with the same
drive letter on both the local and remote machines. This applies to the output
folder as well. For example, if an output folder on the local machine is mapped
to F:, the output folder on the remote machine must also be mapped to F:.
• Actual encoding throughput in an array depends on the network speed more
than the processing speed of the individual computers that make up the array.
Consequently, adding computers may not necessarily increase throughput.
Verify the capacity of your network with your administrator before adding
machines.
• The encoder service is enabled through port 9600 for distributed encoding.
To connect to the JPEG 2000 Encoder on a remote machine with an enabled
firewall, it is necessary to add an exception for this port in the local firewall.
• For Windows 7 users: to enable port 9600, it is necessary to add a rule for TCP
port 9600 in inbound rules as well as outbound rules.
To set a multiple-encoding array:
1. In the Remote Machines section of the JPEG 2000 Encoder main screen, click Add . The
New Remote Machine screen opens.

2. On the New Remote Machine screen, enter the IP address or computer name for a
machine on the network.
