2. DTS Pro Series Network

Encoder Manager’s Guide

2.1. Introduction

The DTS Pro Series Network Encoder system requires periodic attention from a

particular user - the Encoding Service Manager, or the “Manager”.

The Manager is responsible for the administration of resources and Encoder

Users. The Manager’s tasks include periodic maintenance to the DTS Pro

Series Network Encoder database as well as enforcement of policies regarding

disk space usage. The Encoding Service Administrator program

(XencodeAdmin.jar) assists the Manager with the maintenance of the database.

Policy enforcement should be dictated and regulated by the organization that is

using the DTS Pro Series Network Encoder.

2.2. A policy on disk usage

The hard disk where the DTS Pro Series Network Encoder is installed should not

be used as long-term storage for source material and/or subsequent encodings.

While it may contain the base directory for sources and encodings, this space is

not intended to hold these files for extended periods of time. The allowance of

storage for these files should be regarded as strictly temporary. To ensure that

enough free disk space is available at all times; source and encoded files should

be removed from the disk as soon as possible, and properly stored elsewhere.

There is a way to allow the Encoder Users to manage their own files (see the next

topic, User File Management via FTP). If the Encoder Users are managing their

own files, then the Encoding Service Manager’s responsibility in this area is only

to monitor the remaining free disk space, and to encourage the Network Encoder

Users to move their files out of the disk as soon as practical. If the FTP capability

is not used by the Encoder Users then the responsibility for administering the

stored files belongs to the Manager. In either case, database and file

maintenance must be periodically performed by the Encoding Service Manager

using the Encoding Service Administrator program and OS tools.

Manager and User Guide – DTS Pro Series Network Encoder for MAC OSX

1. Terminology

Several terms used throughout this guide need identification.

Types of users

Encoding Service Manager: The user in charge of the day-to-day

administration of the encoding service. This is a regular user, as seen by the OS.

Encoder User: A user of the encoding and related services offered over the

network. This kind of user has no OS-level user account.

SysAdmin: The OS X System Administrator. An OS-level privileged user.

Types of accounts

Administrative account: The OS X account of the SysAdmin.

Encoding Service Manager’s account: A regular OS X user’s account. The

Encoding service resources will be actively managed through this account.

Encoder User’s account: An internal abstraction within the DTS Pro Series

Network Encoder, to provide encoding services to physical users. These users

do not require an OS X user account on the encoding machine. These users and

their accounts are administered through the DTS Pro Series Network

Encoder system.

DTS Pro Series Network Encoder for MAC OSX – Manager and User Guide

To change root directories:

1. Start the Administrator program. A screen similar to the following will display.

Figure 1. Facility administrator initial screen

2. From the Setup menu, choose Set root directory...

Figure 2. Choose “Set root directory”

3. In the dialog box, select the directory you created to designate

it as the Root Directory.

Figure 3. Designate the Root Directory

Manager and User Guide – DTS Pro Series Network Encoder for MAC OSX

2.3. User file management via FTP

Microsoft’s Internet Explorer web browser running on Windows has the ability to

function as a regular file manager over FTP connections. In other words, it is

possible to copy local and remote files into or out of local or remote directories,

and relocate files and directories in a remote location; all using the built-in native

capabilities of the browser. The key requirement is a constant FTP connection to

the remote location using the browser.

Keep in mind that this is a capability of the browser itself. A different browser may

not work.

Please refer to Uploading Packed Files (page 25) for connection details.

2.4. Setting the Root Directory

The DTS Pro Series Network Encoder requires a disk location where the Encoder

User’s files will be stored. In the context of the DTS Pro Series Network Encoder,

this location is called its Root Directory. During installation, the DTS Pro Series

Network Encoder will create a default Root Directory under

/Applications/dts/Facility_Xencode/, and call it DTS_ROOT. Alternatively, you,

the Manager, can create a Root Directory in your OS X user account, and later

notify the Administrator program about which existing directory to use as its

Root Directory.

aNote: You can only specify a new Root Directory if there are no users

registered in the Administrator program. If you are changing the set Root

Directory from one directory to a different one, you will need to delete all

users before the system will allow the change. Deleting a user erases all

information related to that user from the database. See topic Deleting

Users, page 5, for more information on deleting users.

aNote: When setting the Root Directory, avoid folders that have spaces in

their names. The FTP server cannot work with folder names containing

spaces.

aNote: Only an account for which the software was installed has direct

access to the /Applications/dts/Facility_Xencode/ folder and its contents.

If you are specifying a Root Directory other than the default one, it is your

responsibility to set the proper access permissions accordingly.

DTS Pro Series Network Encoder for MAC OSX – Manager and User Guide

Then Click Select

Browse to select root directory

2.6. Adding users

1. Under the User menu, choose Add

Figure 6. Choose “Add”

2. In the dialog box, specify a unique user name and password.

3. (Optional) You may also specify an email address so that the user

can be notified when their jobs are submitted and completed.

Figure 7. Add user dialog

4. Press OK. A directory will be created for the new user under the Root

Directory.

aNote: The maximum number of users is governed by the Network Encoder

adapter key (dongle). When the maximum number has been reached, no

further accounts may be added. Currently, an adapter key for the Network

Encoder permits 99 users maximum.

aNote: User names that include spaces will prevent those users from

accessing their files via FTP.

Manager and User Guide – DTS Pro Series Network Encoder for MAC OSX

The Root Directory is also the storage place for encoding log files. Every time a

user completes an encoding job, a log file with details and outcome of the job

is generated in their folder. A copy is also kept in the Root Directory so that

the Manager has an audit record of all encodings, even if a user deletes their

own copy.

2.5. Configuring email notification (optional)

If you want, you can configure the Network Encoder to send email notification to

users when each of their encoding jobs is submitted and done.

aNote: You will need to have access to an outgoing email SMPT server. Your

network administrator will know this information. If you use Outlook Express

with a POP3 connection, you can find your SMPT server by looking at the

“Server” tab on the account properties page.

Figure 4. Choose “Set email address”

1. Under the Setup menu, choose “Set email address”

Figure 5. Email setup dialog

2. Enter the SMPT server in the top field and enter an Encoder email address

in the bottom field.

aNote: This does not have to be a valid address – the message sent to the

user states that the email is automatically generated and that they should not

reply to it.

You may also need to allow SMPT traffic on the server. Consult with your

System Administrator and refer to Help for OS X.

DTS Pro Series Network Encoder for MAC OSX – Manager and User Guide

3. Under the Job menu, choose Delete.

aNote: This procedure only removes the completed job from the database. It

is still the Manager’s responsibility to manually remove the duplicate log files

from the Root Directory after removing them from the database, to maintain

disk space available in the system.

!Caution: Jobs can only be deleted one-by-one to avoid accidental deletions,

and to enable the Manager to retain a detailed record (elsewhere) of the jobs

that were removed.

2.9. Library handling for local packing

If a user wants to pack a file locally, the user will need to manually obtain a copy

of a necessary library for their platform (Mac or PC) and keep it alongside their

downloaded customized packer. Otherwise the downloaded packer will not be

able to pack the file locally, because it is missing the “Disk Checker”

(DiskChecker.dll for PC, libDiskChecker.jnilib for Mac).

The installer copies both versions of the library (PC and Mac) to the application’s

location (/Applications/dts/Facility_Xencode). The Encoding Service Manager will

need to manually distribute a copy of the appropriate library to each user who

needs it. The user will need to keep the copy of the library and their downloaded

packer together (in the same directory) in order to pack locally.

There are several ways the library file can be manually distributed:

1. Copy the library onto removable media (diskette, CD, tape, etc.) and give it

to the users.

2. The Encoding Service manager can manmually copy the libraries to a

shared location in their local network, where the user may obtain a copy

for their platform.

3. The Encoding Service manager can manually copy the library into a user’s

Encoder account (/Applications/dts/Facility_Xencode/DTS_ROOT/username).

From there, the user can use FTP to copy it to their local machine.

After packing locally, the resulting packed file still must be transferred into the

user’s account at the server before it can be encoded. The user can use FTP

to transfer the file.

Manager and User Guide – DTS Pro Series Network Encoder for MAC OSX

2.7. Deleting users

1. Under the User menu, first choose Refresh audio files to ensure that no

packed audio files are present in the user’s space. You will not be able to

remove the user if there are packed audio files in the user’s directory. Make

sure that the files in the user’s directory are properly archived elsewhere

before removing them and the user from the system.

Figure 8. Choose “Refresh” then “Remove”

2. Under the User menu, choose Remove.

3. In the confirmation prompt, confirm that the user should be removed.

Figure 9. Delete user confirmation prompt

aNote: This procedure does not remove the user’s duplicate log files, or the

user’s folder and its contents from the Root Directory. The Manager should

remove them manually as part of the necessary routine maintenance.

2.8. Deleting Jobs

This is the only way to delete a selected job from the “Completed Jobs” list.

This action removes completed jobs from the database only. Users are not

allowed to delete their own jobs from the database. This ensures that a record of

the encoding job is kept as long as the administrator wants, even if the output

encoded file and log files are removed from the user’s directory and duplicates

are removed from the Root Directory.

1. From the User’s pane, select a username.

2. From the Completed Jobs pane, select a job to delete.

DTS Pro Series Network Encoder for MAC OSX – Manager and User Guide

2. Enter your User name and Password. Then click Log In. The Home

Page will display.

Figure 12. Home Page

aNote: Once logged in, you will remain so until the Log Out button is

pressed, as long as you are using the service. However, you will be

automatically logged out if you do not interact with the server for a period of

five minutes.

From this page, you can do these tasks

1. Click on the Download Packer button.

Manager and User Guide – DTS Pro Series Network Encoder for MAC OSX

3. Network Encoder User’s Guide

3.1. Log on

The Network Encoder is a web browser-based service. You will use it in the

same manner from a web browser on any platform.

aNote: In order to get the full service, your web browser must have

JavaScript installed and running. This is automatically set, if you are using MS

Internet Explorer, on the default web settings level.

1. Access the service. Type the following address into the address bar of your

browser, then send the request:

http://[localhost]:9006/Xencode/main (the address is case-sensitive)

When browsing from a remote host, substitute the IP address of the

Network Encoder host for [localhost] in the above URL.

For example, if the Network Encoder’s IP address is 172.16.0.1, then the

access URL for all clients is:

http://172.16.0.1:9006/Xencode/main

1. Select channel mapping L C R for the front channels. See Table 1, page 18.

2. Select Ls Rs channel mapping for the back channels. See Table 1, page 18.

3. LFE is set to ON. See Table 1, page 18.

Manager and User Guide – DTS Pro Series Network Encoder for MAC OSX

A File Download screen will appear, prompting you to choose how

to handle the file dtsPacker.jar.

Figure 13. File Download screen

2. Save the downloaded file to your local system.

A typical “Save As” dialog will display, prompting you to identify the

destination folder for the downloaded file.

After saving, a Download Complete dialog may prompt you to Open

the file (or open the folder).

3. Activate the .jar file that you just downloaded. (This starts the File Packer.)

3.3. Using the file packer

Start with the File Packer. The purpose of the File Packer is to bring all the source

files together into a single file. The File Packer checks the length of the files and

their sample rates, to ensure that you are supplying the encoder with source files

that are compatible with it.

Upon starting the program, the File Packer initial screen will display.

9. (Optional) Add your company name, project name, or other details here.

10. Frame rate: If the audio track is intended to sync with video, be sure to

match its frame rate. If the video reference is “drop frame”, you MUST select

“drop frame” here.

29.97 (drop or non-drop)

If it is important to match the start of the audio track to some specific point in the

video, enter the Start time here, in hours:minutes:seconds:frames (hh:mm:ss:ff)

format. The End time will be calculated automatically, based on the length of the

Input Files and the selected frame rate.

11. The Input Files section of the screen is where you select the individual

source file to be assigned to each encoded channel. (See the “Special Case”

following step 12.)

Click the cursor on the left-hand column (the “L…” in this example) to open a

file selection window (shown below).

Browse for an input file for the L channel, then select it.

Manager and User Guide – DTS Pro Series Network Encoder for MAC OSX

4. Sample rate is set to 48 kHz. The Sample rate here must match the sample

rate of the source files. See note 1, after step 12, page 16.

5. 3 dB Rear channel attenuation is left OFF.

3 dB rear channel attenuation is used in cases where you have a theatrical

master that has not been remixed or repurposed for DVD, and the rear

surrounds (right and left) are typically 3 dB higher than they should be for

home theater.

6. Determine the location for the output files.

Choose Local to pack a file locally. Then go to step 7.

or Choose Network to pack files straight to Network Encoder.

The User Name field will display your user name. Go to step 8.

7. This field only displays if Mode is set to “Local” meaning that the output file

will be placed on your local computer.

Identify the directory where the output files will be located.

Click Browse and navigate to the parent (the next higher directory) of the

desired directory.

Click the target directory name to select it, then click Select.

aNote: To pack locally you will need an additional library. See 2.9 on page 9.

Keep your personalized packer and library together.

8. Type a name for the packed file that you will produce.

DTS Pro Series Network Encoder for MAC OSX – Manager and User Guide

1514

aNote 1: If the sample rate of the input file does not match the sample rate

you have chosen for the output file, a red outline will appear around the input

file’s sample rate, as shown in this example.

Input file sample rate does not match the selected output sample rate. In this

case, you must change the output sample rate to match (step 4) or provide

inputs of the proper sample rate.

aNote 2: If the duration (length) of an input file does not match the duration of

another input file, a red outline will appear around the input file’s duration, as

shown in this example.

The duration of all input audio files must be the same.

13. Next, choose Pack remote file or choose Pack local file (if you are going

to pack the file now but it will be encoded later – see page 20). Choose

Close, if you do not want to continue. (Your selections so far will

be discarded.)

Click “Pack remote file” to generate the packed .agm file at the server.

(If the output file already exists, packing will be aborted.)

You will be prompted to re-enter your password at this time.

This prompt will display when the packing is finished. (See Encoding

Immediately after Packing, page 19).

If “Pack local file” is selected, this prompt will display when the packing is

finished. (If the output file already exists, you will be prompted to overwrite it.)

Manager and User Guide – DTS Pro Series Network Encoder for MAC OSX

To select, double-click on the file in the list or highlight the

file and click Open.

12. Repeat step 11 for the other channels.

Input files have been selected for all channels. For each input file, the sample

rate, bit depth, and duration is identified. See note 1, below.

Use the duration information to check that the input files are identical in

length. See note 2, below.

At bottom left, the estimated file size is displayed.

Make sure there is enough space in your output directory to

store a file of this size.

aSpecial Case: This packer will accept a stereo source file to assign to a

single channel.

The pulldown on the right is to select channel 1 or channel 2 from a

stereo source file.
