2 CaptiView Installation Procedure

2.1 Introduction

The CaptiView is an in-theater closed caption viewing system for the hearing impaired.
The system is composed of three key elements: CaptiView license, CaptiView display, and
Captiview transmitter.

The Display Screen is 31 x 3 lines for a total of 93 characters.

Figure 3: CaptiView Display

 CaptiView Display is a portable LCD screen attached to a flexible arm that fits in any

standard cup holder on a theater seat (Figure 3).

Figure 4: CaptiView Transmitter

 CaptiView Transmitter is a custom encrypted wireless dongle that is plugged into a USB

port on a Doremi Cinema Server or into the Doremi Fidelio and AccessLink products
(Figure 4).

Warning: DO NOT flip the switch on the Doremi Cinema side of the transmitter (Figure 4). This
will delete the firmware and lead to the device becoming inoperable.

2.2 How to Set Up the CaptiView System on a Doremi Cinema Server

Ingest

Button

2.2.1 Installing the License

The CaptiView license is required to enable a Doremi Cinema Server to playback the Closed
Caption data contained in the Digital Cinema Package (DCP). The license needs to be installed
before setting up the CaptiView system. Contact your local Doremi support team to receive the
Closed Caption license (Section 0).

 Insert the USB drive that contains the Closed Caption license update into the unit.
 The Ingest Manager GUI window will appear (Figure 5).
 Select the file that contains the CaptiView license and then click on the Ingest button

(Figure 5).

 Reboot the server to complete the ingest process.

Figure 5: Ingest Window

 Once the ingest is complete, check the license information by going to Menu →

Control Panel → License Manager.

 Follow the steps below for configuring the CaptiView System to finalize the set up

process:

D2K.DP.000469.DRM Page 10 of 27 Version 2.1
Doremi Labs

Note: Doremi Cinema Servers (DCP-2000, DCP-2K4, or ShowVault) must have software 2.0.0-

Device

Manager

0 or higher to support the CaptiView. It is recommended to test the CaptiView system to ensure
that it operates correctly before using it in a live theater.

 Plug the CaptiView transmitter dongle into a Doremi Digital Cinema Server USB port

only.

 Go to Menu and then click Control Panel.
 Select and open the Device Manager icon (Figure 6).

Figure 6: Control Panel Window

 From the Device Manager window, click on the Add button.
 The Add Device window will appear.
 Select the Closed Caption device.

Figure 7: List of Devices - Closed Caption Example

 Click the Add button (Figure 7).
 The user will now be back to the Device Manager GUI to finish configuring the device.

2.2.2 CaptiView Configuration

To finish configuring the device, complete the fields in the Closed Caption Configuration window
(Figure 8).

 Check the Enabled box to enable this feature.
 It is recommended to leave the default settings as they are, except for the Auditorium

field.

 In the Auditorium field, choose any channel other than 0. For example, choose 1, 2, 3,

etc., but do not leave the channel set at 0. The number, once saved, will be saved to the
USB transmitter which then must be power-cycled by unplugging and then re-plugging
the transmitter. This applies to software versions 2.0.10 and higher.

Note: To change the current auditorium number while using software versions 2.07 or below,
contact Doremi Technical Support to receive a hot fix. In software version 2.0.10 and higher, the
user can change the auditorium setting from the Device Manager GUI.

 Define the Play Offset, Idle Text, and Idle Time.

o Play Offset: This feature offsets the Closed Captioning data in the form of

milliseconds.

o Idle Text: The default text that is shown on the display.
o Idle Time: The time it takes for default Idle Text to appear after loss of input.

 Click the Save button.

Charging

Cable

Receptacle

Figure 12: Connection Message

Note: If the CaptiView Display is being charged while it is on, it will show as charging even

when it is not charging anymore, until the device is turned off and on again. The charge time will
take approximately 2 hours to complete and will last for 24 hours of playing time.

 Once the CaptiView system is connected, play a Digital Cinema Package (DCP) with

closed captioning to check if it is working properly.

Note: In the event that the Digital Cinema Server does not detect the CaptiView Transmitter,
follow the steps below:

 Shut off the server. Do not reboot or log off.
 Remove all USB devices.
 Power the server back on.

 Plug the CaptiView Transmitter in and the server should detect it.

2.2.4 Charging the CaptiView

To charge the CaptiView, connect the charging cable to the receptacle (Figure 13).

Figure 13: Charging Cable and Receptacle

 Connect the mini USB end into the charging port on the CaptiView (Figure 14). Connect

the other end to a wall outlet.

Figure 14: Charging Port

 When the device is in the On position (Figure 9), the screen will indicate that the device

is charging (Figure 15). When it is in the Off position, the screen will not be visible but it
will continue to charge. After about two hours, the device will be fully charged.

4 Appendix A: SB430-10 Set Up Instructions

Doremi provides two hardware solutions, the AccessLink and CaptiLink, to use the CaptiView
system on Non Doremi cinema servers. Both of these products utilize the SMPTE430-10
protocol. There are two ways to set up these devices via the SMPTE430-10 protocol. The
Ethernet port is the primary way to set up the device. The secondary way is to use the serial
port, which is a backup mechanism if the Ethernet port fails or does not work properly (Figure 17
and Figure 18).

D2K.DP.000469.DRM Page 22 of 27 Version 2.1
Doremi Labs

4.3 Upgrading the SB430-10 Software

There are two ways to upgrade the software on the AccessLink or CaptiLink. One way is to use
an FTP client (e.g., Core FTP or Filezilla) and the other is to use a USB flash drive to perform
the upgrade.

4.3.1 FTP Client

 Make sure that an FTP client is installed on the computer.
 Turn the SB430-10 on and make sure it is able to ping to the network.
 Open the FTP client and connect using the IP of the AccessLink or CaptiLink under port

21. Login as the root user and enter the appropriate password.

 Add the update package (".pkg file") to the folder, "/doremi/etc/rc.once," and then

reboot.

 To check if the upgrade was successful, open an SSH session and type the following

command: 'more /doremi/etc/version' and make sure that the version matches that of
the ".pkg" file.

4.3.2 USB Flash Update

 Create a folder in the USB drive and name it doremi, then inside the doremi folder

create another folder and name it "update." For example, '/doremi/update/.'

 Copy the ".pkg" file to the path of the USB flash '/doremi/update/' then safely unmount

the USB flash drive.

 Put the USB flash drive in place of the CaptiView transmitter. Wait for the light to stop

blinking and then do a reboot or power cycle.

 To check if the upgrade was successful, open an SSH session and type the following

command: more /doremi/etc/version and make sure that the version matches that of
the ".pkg" file.

4.4 Changing the Auditorium on the SB430-10

 Connect to the AccessLink or CaptiLink via ssh session.
 Login as username root.
 Type: echo -n aud_number > /doremi/etc/s430-10/audi.conf and then press the Enter

key.

 Reboot for the changes to take effect.
