The Kaleidescape Strato Installation Guide describes how to set up and configure the Strato movie player, and add new components to an existing installation.

Kaleidescape Strato and Strato C Movie Players

The Kaleidescape Strato and Strato C movie players are 4K Ultra HD movie players with high dynamic range (HDR) capability.  Strato includes internal movie storage, while Strato C has a compact form factor without internal movie storage.

A Strato with internal movie storage can store and play up to 180 4K Ultra HD, 330 Blu-ray quality, or 1500 DVD quality movies on its internal hard drive.
Strato C is intended to be used as part of a larger system that includes Strato players with storage, or a Terra movie server.
This document covers the Strato movie player (with storage).  There is a separate installation guide for the Strato C.


Benefits of Strato


Strato is easy to set up, and provides amazing convenience without compromising quality.
Strato enables you to:

  • Download and play 4K Ultra HD movies from the Kaleidescape Movie Store with audio and video quality superior to that found in many commercial theaters
  • Download Blu-ray quality and DVD quality movies with identical fidelity to those optical formats
  • Use the comprehensive Kaleidescape Movie Guide to easily navigate your collection and directly access memorable scenes, songs, and special features

Strato supports easy integration into audio, video, and whole-house control systems.


Supported Configurations


Strato can be used by itself as a complete Kaleidescape system, or it can be used with additional Strato or Strato C movie players and/or Terra servers as part of a multi-zone system.

In a multi-zone system, up to four Strato players with internal storage may be used. This configuration is suitable for installations where one or two movies will be played at the same time in the household.

Beyond four zones, or if more than two simultaneous movie playbacks are required, the system should be built with Strato C players and one or more Terra servers.

Kaleidescape recommends that a large system be designed such that all of its storage is in the Terra servers (i.e., using only Strato C players), because Terra can support more simultaneous playback streams.  However, if circumstances dictate, you can still use up to four players with internal storage, with the important limitation that an individual Strato player with storage can only support two simultaneous movie playbacks (one on the player itself plus one being sent to a remote player, or two remote playbacks).                           

Gigabit Ethernet connections are required for all components in a multi-component system.  100Base-T Ethernet networks are not acceptable because of the bandwidth required for 4K Ultra HD.

Strato players with storage have built-in Wi-Fi, which may be used when Strato is installed as a standalone, single-component Kaleidescape system.

Physical Installation

Planning the Installation

Ventilation and Clearance

Use the following guidelines when installing system components to ensure proper clearance and ventilation. These guidelines apply to all installations including rack mounting.  (Rack-mount hardware sold separately.)
  1. Mount components in a location with adequate ventilation.
  2. Check for proper grounding if installing components in a rack.
  3. Maintain a 2 in. (5 cm) clearance in back and a 1 in. (2.5 cm) clearance in front and on the sides.

Power Requirements

Kaleidescape component power supplies are universal input and operate on any nominal line voltage between 100–240 V, and frequency between 50–60 Hz. Verify that power outlets are grounded, and preferably shielded from power surges and brownouts.
Kaleidescape recommends a grounded outlet with a high-quality surge protector for the power source for players and servers. A UPS is optional.

Network Requirements

A Gigabit Ethernet network is recommended, and is required when Strato is used with any other Kaleidescape components.  Connect Strato using a shielded Ethernet cable.  The built-in Wi-Fi may be used when Strato is used as a single-component standalone system.

Audio and Video components

Before beginning the installation, determine the type of the display and audio equipment that will connect to your Strato.
Strato supports the following outputs:

  • High-Definition Multimedia Interface (HDMI).  HDMI 2.0 and HDCP 2.2 are required for 4K Ultra HD content.  HDMI 2.0a is required for HDR.
  • HDMI (Digital stereo or multi-channel)
  • Coaxial (Digital stereo or multi-channel)
  • Optical (Digital stereo or multi-channel)

Installing Strato

Tabletop / Shelf Installation

1. Choose a suitable location that is sturdy enough to hold Strato.  Strato weighs approximately 15 pounds. 

2. Place Strato onto the tabletop or shelf. Strato ships with feet attached.

3. Installation is complete. You may now proceed to the Audio and Video Connections section below.

Rack Installation

1. Installing Strato in a rack requires the Strato rack-mount kit (KMOUNT-K0509-1), sold separately.
2. Strato requires two rack units of space. Determine a location in the rack to install Strato.
3. Place Strato upside down on a soft, clean surface.
4. Assemble rack sides into front panel as shown:

Audio and Video Connections

User-added image
Connect network, audio and video cables before connecting the AC adapter.

In order to play 4K Ultra HD content with Strato, the display must support HDMI 2.0 and HDCP 2.2. High Dynamic Range (HDR) content requires HDMI 2.0a and an HDR-capable display that supports the SMPTE HDR (“HDR10”) standard.

When the HDMI signal passes through other components before reaching the display (e.g. an audio receiver), all of those components must also support HDMI 2.0 and HDCP 2.2.  Otherwise, Strato will have to reduce the video quality to accommodate the limits of those components.

For this reason, Strato has two HDMI ports.  The primary HDMI port (labeled VIDEO) carries both video and audio information.  The secondary HDMI port (labeled DIGITAL AUDIO) carries audio information only.

User-added image

If the audio equipment does not support the necessary HDMI capabilities, you should connect the display directly to the VIDEO HDMI port, and connect the audio equipment to the DIGITAL AUDIO HDMI port.  This will ensure that you achieve the highest possible video and audio quality.

If using a single HDMI connection, be sure to connect to the VIDEO HDMI port.  The secondary HDMI port does not support video output.

Network Connection

A wired Gigabit Ethernet network connection is recommended, and is required if any other Kaleidescape components are used with Strato (e.g. another Strato player, a Terra server, etc.).  Connect Strato using a shielded Ethernet cable.  If using a single Strato player by itself, you can use the built-in Wi-Fi if a wired connection is not possible.

Power Connection and Startup

After making the audio, video and network connections, make sure your television is set to the correct HDMI input, then connect Strato’s AC adapter.  You should see the Kaleidescape logo on the display, and after a few minutes, the initial setup menu appears.
If you do not see the Kaleidescape logo and the setup menu, first check that Strato has power.  Check the AC adapter’s connection, and make sure that the Kaleidescape logo on the front of the player is glowing.  If it is not, try pressing the power button, located in the lower right corner of the front panel.
If you still see no image, double-check that the correct input is selected on the display.  If there are other devices in the video chain, like audio receivers or switches, ensure that they are configured properly.  You may want to try connecting Strato directly to the display with the supplied cable to rule out compatibility issues with intermediate devices or cables.

Getting the Most out of Strato     

Strato is a high-performance source device, capable of playing 4K Ultra HD content encoded at data rates of 100 megabits per second (Mbps) or higher.  It supports 10-bit color, and high dynamic range (HDR) content.  Taking full advantage of Strato’s capabilities requires careful attention to HDMI connections, cabling, and configuration.
This section discusses background information on HDMI and HDCP, and best practices that will help you to maximize Strato’s performance within the larger A/V system.
In particular, we discuss cases where using the second HDMI port will allow you to achieve maximum video and audio quality, even when audio equipment does not support HDMI 2.0 and/or HDCP 2.2.
We also include some information on ensuring your installation is set up properly for HDR.  We conclude with a brief tutorial covering the use of Strato’s new
Show video capabilities and status tool in the Browser Interface.

About 4K HDR, 4K Ultra HD, HDMI 2.0a, and HDCP 2.2

Achieving Strato’s highest video output quality requires a 4K HDR display capable of receiving and displaying an 18 Gbps HDMI 2.0a signal with HDCP 2.2. 

As well, if Strato is connected to the display via intermediate devices (such as an audio processor, an A/V matrix switch, an active HDMI cable, or an HDMI extender), every device in that chain must support the required HDMI and HDCP versions in order to display 4K HDR and 4K Ultra HD at full fidelity.

The earliest 4K displays may not be able to display 4K Ultra HD content from Strato at all, and other displays may be able to display 4K Ultra HD content, but unable to handle all of the latest features, like HDR.  This section describes the features present in different 4K displays, and how Strato will interoperate with those displays.

First and foremost, HDCP 2.2 copy protection is required to play 4K HDR and 4K Ultra HD content with Strato.  Some early 4K display devices do not support HDCP 2.2, and will not be able to display 4K Ultra HD content when used with Strato.  Consult with the display’s manufacturer to see if an upgrade is available.

If a display does not support HDCP 2.2 copy protection, but does support HDCP 1.x, Strato will down-scale the 4K Ultra HD content and output it at up to 1080p resolution.  4K HDR content cannot be down-scaled.

Strato also requires HDMI 2.0 to properly display 4K Ultra HD content (2.0a for HDR content).  One might expect that a display that supports HDCP 2.2 is also
an HDMI 2.0 display, and vice-versa.  Unfortunately, the situation is more complicated.

Some early HDMI 2.0 displays do not support HDCP 2.2.  Also, some HDMI 2.0 displays only support data transfer at 10.2 gigabits per second (Gbps), rather than the maximum 18 Gbps included in the HDMI 2.0 spec.  The lower speed places some limits on how Strato displays 4K HDR and 4K Ultra HD content.

Note that some equipment describes HDMI bandwidth in terms of frequency rather than data rate.  A 10.2 Gbps connection or cable may also be called 340 MHz, and an 18 Gbps connection may also be called 600 MHz.

The chart below summarizes how HDMI and HDCP capabilities affect Strato playback.

About Bit Depth

Digital images represent each pixel in an image as a series of bits (ones and zeroes).  The number of bits used for each pixel is referred to as the “bit depth,” and is often expressed in terms of the number of bits used for each signal component.  For example, an “8-bit” RGB image uses eight bits of data for red, eight bits for green, and eight for blue, for a total of 24 bits per pixel.

DVD and Blu-ray discs are examples of formats that use 8-bit color.

When more bits are used for each pixel, the digital information can represent more subtle differences between the colors.  Kaleidescape’s 4K HDR and 4K Ultra HD downloads use 10-bit color (30 bits total), which produces images with fewer artifacts, like stair-stepped bands of color visible in images of a blue sky.

About HDR

High dynamic range (HDR) content incorporates both a wider color gamut – meaning that it can display more vivid and lifelike colors – and the ability to display very bright and very dark images simultaneously.  This combination produces remarkably realistic images.

Strato fully supports 10-bit 4K HDR content, at up to 60 frames per second, provided that Strato is connected to a display that supports 4K HDR.  As of 2017, new 4K displays typically all support HDR.  HDR support is less common in older displays.

See the Supported 4K Ultra HD Modes section on page 28 to learn how Strato can help you discover the capabilities of the connected display.

About Chroma Sampling

In addition to bit depth, another factor in how images are displayed is how the color information is represented.  This is usually expressed in terms of three numbers separated by colons, like 4:4:4 or 4:2:0. 

The details of this notation are beyond the scope of this document, but in summary, 4:4:4 has discrete luma (brightness) and chroma (color) information for every pixel in an image. 4:2:0 has discrete luma for every pixel, but the chroma is averaged across 2x2 clusters of pixels.

4:2:0 significantly reduces the amount of data required for each frame, so a 4:2:0 signal requires less bandwidth than a 4:4:4 signal.  In a moving image, the difference in chroma resolution is not perceptible to most viewers.

4K Ultra HD movie content is encoded as 4:2:0 (as are Blu-ray and DVD discs and Blu-ray quality and DVD quality downloads), so a 4:2:0 connection does not compromise video playback quality.

The Kaleidescape onscreen display can be rendered with 4:4:4 color sampling on displays that support it, if the HDMI connection supports 18 Gbps.  This will produce the most detail when looking at images in the onscreen display, such as the Movie Covers view.


HDMI Cables

Carrying an 18 Gbps HDMI signal reliably requires a high-quality cable.  Kaleidescape recommends cables that meet the following specification:
  • HDMI High-Speed cable tested to at least 18 Gbps
  • Double Shielded
  • AWG number for the conductors of 26, 24, 22, or lower
A number of passive cables in lengths up to 15 feet have worked well in our testing.  This includes cables that carry Premium HDMI Cable Certification, and cables that have been given 4K-18G-DC certification by DPL Labs.

For cables longer than 15 feet, it may be necessary to use an active cable (including fiber optic cables) or an extender system. However, in our testing, many active cables and extenders have been unable to reliably support 18 Gbps signals in all situations, despite how they are labeled.

Check the Kaleidescape Knowledge Base for the latest HDMI cable information.

HDMI Best Practices

To achieve the best possible audio and video performance in a given installation, you may need to use both of Strato’s HDMI outputs, or adjust some of Strato’s settings.  The approach you take will depend upon the capabilities of the display and any intermediate devices like switches or audio processors.

Best Quality, Single Connection

To achieve maximum image quality, Strato must be connected to a display that supports HDMI 2.0a at 18 Gbps with HDCP 2.2.  If the signal is routed through an audio receiver, it must also support both HDMI 2.0a at 18 Gbps and HDCP 2.2.  Such an installation allows for maximum video quality at all 4K Ultra HD frame rates, and fully supports 4K HDR at up to 60 frames per second.

Best Quality, Dual Connection

A common situation is one in which the display supports HDMI 2.0 or 2.0a at 18 Gbps with HDCP 2.2, but the audio receiver either does not support HDMI 2.0 and HDCP 2.2, or supports HDMI 2.0 at only 10.2 Gbps.  You can still achieve maximum video quality in such a system by using the second (audio-only) HDMI port on Strato.

When the display supports HDMI 2.0 and HDCP 2.2, but the audio equipment does not, connect the display directly to Strato’s primary (VIDEO) HDMI port, and connect the receiver or audio processor to the secondary (DIGITAL AUDIO) HDMI port.  This dual connection allows the full video capability of Strato to be delivered to the display, while still providing full fidelity audio to the receiver.


Very Good Quality, Single and Dual Connections

If the display supports HDMI 2.0 and HDCP 2.2, but at 10.2 Gbps, Strato can still output 4K Ultra HD, including 4K Ultra HD at 60 frames per second.  However, at 60fps, video will be limited to 8-bit color, which can produce color banding with some content.

With such a display, configuring Strato to “Allow Display Mode Changes” in the Video tab of the browser interface’s Settings dialog will allow Strato to switch to 24 frames per second for film content.  At 24 fps, Strato can output 10-bit color and HDR content even over a 10.2 Gbps link for displays that support it, so the image for film content is identical to what you would see on an 18 Gbps connection. 

As with the 18 Gbps connection options described above, you can connect the audio equipment to the second HDMI port to if the audio equipment has HDMI or HDCP limitations that the display does not.

Even if the display only supports a maximum of 10.2 Gbps, consider choosing cables that are tested to work at 18 Gbps or higher, especially when cables are run in-wall or in other difficult to replace installations.  This will help to ensure a smoother upgrade path to a new display in the future.


Strato provides a great experience with a 1080p display.  4K Ultra HD content is down-scaled for display at 1080p, and the Kaleidescape onscreen display runs at a full 60 fps.  Using Strato with a 1080p display is a good choice in an installation that has a mix of 4K and 1080p displays, especially if the 1080p displays may be upgraded over time.  If you can use 18 Gbps-capable cables, a later upgrade should also go more smoothly.

Note that while 4K Ultra HD content can be down-scaled, 4K HDR content cannot. This is because 1080p displays don’t support HDR, and Strato cannot convert HDR content for playback on non-HDR displays.


Verifying HDMI Video Performance

Once your Strato has been connected and configured, you should verify that you are seeing the expected video resolution and frame rate.

Strato includes a new tool to help you ensure that things are working as expected.  Go to the system’s Browser Interface, and click on the Settings tab.  You should see the Components page.

In the section for your Strato, click the Settings button:

User-added image

In the window that opens, click the “Show primary HDMI port capabilities and status” button:

User-added image

You will see a new “
Show video capabilities and status” view, divided into three sections:
  • Supported 4K Ultra HD Modes
  • Supported HDMI Features
  • HDMI Video Status
These sections are described below.

Supported 4K Ultra HD Modes

User-added image

This section summarizes the 4K Ultra HD capabilities of the device(s) connected to the primary HDMI port, as detected by Strato.  If Strato is connected directly to the display, then this shows the capabilities that the display is reporting.  If Strato is connected to the display via an audio processor, an HDMI switch or matrix, or other intermediate equipment, then this section shows the capabilities of the combined display chain, including any limitations imposed by the intermediate devices.

This section is divided into NTSC, PAL and Film sections.  The icons provide a quick summary of the display’s capabilities for each of these formats.  The paragraphs in the right column give more detail.
Note that when you see “30 bit” or “24 bit”, this refers to the number of total bits of color information.  These same modes are often called “10 bit” and “8 bit”, which refers to the number of bits for each color component.  Since the signal has three color components, 10 bits per component equals 30 bits, etc.

Supported HDMI Features

User-added image

HDMI Video Output Status

User-added image

This section shows the output status of the HDMI port, as of when the window was opened or refreshed.  It works when displaying the onscreen display, and while playing content, so you can use it to confirm that 4K Ultra HD content is being displayed at full resolution, that 1080p content is being up-scaled, and that the expected frame rates and color information are being output.

The colored indicators show whether content is being passed through in its native format, if it is being up- or down-scaled, or if there is a problem.  The status text gives more details.

Click the Refresh button at the bottom of the window to easily update the status information, for example when trying different types of content.

The example above shows Strato connected to a 4K projector, displaying the onscreen display.  This particular projector does not support 18 Gbps HDMI 2.0, so the onscreen display is being rendered at 60 frames per second with YUV 4:2:0 color sampling and 8-bit color.

Here is another example:

User-added image

The example above shows Strato playing 4K Ultra HD film content on the same projector.  Strato has been set to minimize display mode changes, so it is converting the 24 fps film content to 60 fps.  At 60 fps, this projector is not able to accept deep color, so Strato is sending standard 24-bit (8 bits per component) color to the display.  Note the yellow indicator indicating a reduction.

With this projector, the installer should consider configuring Strato to allow display mode changes when starting movie playback.  This would allow Strato to switch to 24 frames per second on film content, which would in turn allow Deep Color information to be passed to the display.

One final example:

User-added image

In the example above, Strato is taking full advantage of an 18 Gbps connection to play a 60 fps 4K HDR movie on a display that supports the maximum possible HDMI 2.0a connection.  Note how HDR content shows differences in the Colorspace and Dynamic Range lines compared to the examples above.


About Lossless Audio

Strato supports advanced, lossless audio formats including Dolby TrueHD, DTS-HD MA, Dolby Atmos, and DTS:X.  Strato sends these formats as a bitstream over HDMI to a compatible audio processor. 

In order to enjoy lossless audio output from your Strato, you must enable bitstream audio output in the player’s Browser Interface Settings page.  Go to the system’s Browser Interface, and click on the Settings tab.  You should see the Components page.

In the section for your Strato, click the Settings button:

User-added image

In the window that opens, click the Audio tab, then select Bitstream pass-through.  Click OK to save the setting.

User-added image

Bitstream audio can be output from one HDMI port at a time.  Strato sends the bitstream audio to the DIGITAL AUDIO HDMI port if it detects a connection on that port.  Otherwise, it sends the bitstream audio to the VIDEO HDMI port.

Troubleshooting HDMI Connections

If Strato is connected to a display using high quality cables that satisfy the specification given earlier in this document, and if all components support HDMI 2.0 and HDCP 2.2, problems should be rare.  However, if they do occur, here are some things you can try.

Check HDMI Port Capabilities

Some display devices and A/V components do not support 18Gbps HDMI 2.0 and HDCP 2.2 on every port.  This includes certain Sony displays.  Ensure that you are using an HDMI port that supports 18Gbps HDMI 2.0 and HDCP 2.2.

Check Device Settings

Some display devices modify their HDMI behavior based upon user settings.  For example, some Samsung displays have an “HDMI UHD Color” setting that must be enabled before the display will accept an 18 Gbps signal, and some Sony displays have a similar “HDMI signal format” setting.

Check Device Software/Firmware

4K Ultra HD – especially at at 18 Gbps data rates – is a new and demanding format.  Some displays, audio processors, or other components may need software or firmware updates to handle it properly.  Check with manufacturers to ensure that the software in all of your components is up to date.

Use the Show video capabilities and status Tool

Use the Show video capabilities and status Tool described in the previous section.  Verify that the “Supported 4K Ultra HD Modes” and the “Supported HDMI Features” match the published specifications of your display device.  If they do not, the display may be incorrectly reporting its capabilities, or an intermediate device (audio processor, active HDMI cable, etc.) may not match the capabilities of your display.  Double check the intermediate devices, and consider temporarily connecting Strato directly to the display to help isolate the problem.  You can also consider using the Advanced Video Settings (described below) to override some features.

Check HDCP Status

If the onscreen display works properly, but you get video dropouts or no picture at all when playing a movie, the problem may be related to HDCP copy protection.  The onscreen display does not require HDCP, but movie playback does.  The Show video capabilities and status Tool should give you an indication of HDCP status during movie playback (click Refresh if necessary).  Sometimes a marginal cable will pass a video signal, but be unable to maintain the HDCP connection.

Try Alternate Cables

Problems with signal integrity, such as signal loss in a long cable, may also affect Strato’s ability to detect display capabilities and achieve an HDCP connection with the display.  Try connecting Strato to the display using a different cable, or try temporarily relocating Strato and using a shorter cable that meets the requirements in this document to see if the problem goes away.

Reduce HDMI Speed

Intermittent problems are almost always related to signal integrity.  The display and intermediate devices may all support 18 Gbps connections, but the cable may be unable to carry that speed reliably.  You can try temporarily forcing Strato to use 13.5 Gbps or 10.2 Gbps instead.  This can help to identify whether the problem is related to signal transmission.

To force Strato to use a lower speed connection, go to the system’s Browser Interface, and click on the Settings tab.  You should see the Components page.  In the section for your Strato, click the Settings button:

In the window that opens, scroll to the bottom and click “Show Advanced Video Settings”:

Scroll down to the “4K Ultra HD Support” section, and click the radio button next to HDMI 2.0 13.5 Gbps or HDMI 2.0 10.2Gbps, then click OK.  Try 13.5 Gbps first, since this imposes fewer limitations on how content is displayed.

Once you’ve clicked OK to save the setting, stop your content if it was playing, and then try playing your content again.

The advanced settings can also be used to compensate for problems that arise when a display or intermediate device does not correctly report or pass EDID information.

Changes in the HDMI Display Chain During Playback

In certain installations (typically involving an HDMI matrix switch), it is possible for an HDMI device to join the display chain while movie playback is occurring.  For example, a second zone may select the same video source.

If the first zone supports HDMI 2.0 and HDCP 2.2 but the newly added zone does not, the addition of the second zone will cause the HDCP 2.2 link to become invalid.  Video in the first zone will go blank, and the second zone will also see no video signal.  If playback is stopped and then resumed, Strato will have an opportunity to reconfigure the HDMI output and playback may be able to proceed (although at reduced resolution for 4K Ultra HD content).

Try to avoid situations in which different HDCP and HDMI versions may come and go to avoid disruptions to the viewing experience.


Control Systems

There are several Kaleidescape options available for controlling Strato.

•       Kaleidescape Remote (included)
•       Kaleidescape App for iPad (free download)
•       Kaleidescape Child Remote (optional purchase)

Strato can also be controlled by several types of third party control devices.

•       Infrared (IR) remotes
•       Home control systems (which may include touch panels, handheld remotes, mobile apps, etc.)

Kaleidescape provides control modules along with touch panel templates and sample programs for most leading control systems. Kaleidescape also provides databases and IR codes for popular IR remotes.

For specific product support including modules and reference manuals, go to and click on Control Systems


A control device can communicate with Strato with IR, or by using a simple text-based protocol over the network.

For more information on control connections, refer to the Kaleidescape System Control Protocol Reference Manual at and the IR Hex codes at

Kaleidescape Control Devices

Kaleidescape Remote

Strato comes with a backlit IR remote control. It features one-button access to features such as Intermission and Shuffle, while the Movies button User-added imagetoggles views between List, Covers and Collections. The Music button User-added image provides quick access to the Songs collection.

The Volume and Mute buttons can be programmed to control the volume on the TV or other audio device:

1. Press and hold the Info and Pause buttons at the same time. When the indicator light at the top of the remote begins blinking, release the buttons. The indicator light stays on. The Kaleidescape Remote is now in programming mode.

Place a remote that already controls the volume flat on a table with the Kaleidescape Remote about 6 inches (15 cm) away.

User-added image

3.     The following steps have to be repeated for the Mute button and both Volume buttons.

•       Check that the indicator light is still on. If it is off, repeat Step 1.
•       Press and release the button on the Kaleidescape Remote for the function you want to program.
•       Press and hold the button for the same function on the remote that already controls the volume for two seconds.
•       The indicator light on the Kaleidescape Remote blinks twice to indicate success. If the indicator light blinks four times, try again.
4.     When finished, press the OK button on the Kaleidescape Remote. The indicator light blinks twice to confirm programming is complete.

Kaleidescape App for iPad

The Kaleidescape App for iPad provides an immersive experience for browsing and searching your collection of movies. The app extends the Kaleidescape experience to the iPad, displaying your movie collection with vivid high-resolution cover art, synopses, and other details.

The Kaleidescape App for iPad includes volume controls and a Return button for integration with other control systems. The following is a typical use case for the Return button:

•       The user is running a home control app on an iPad and wants to use their Kaleidescape System.
•       The user chooses the Kaleidescape source within the home control app.
•       The controller app configures the A/V equipment for use with the Kaleidescape System, and launches the Kaleidescape App for iPad by opening a specific URL.
•       The user can browse movies and music, play any selection, and control the Kaleidescape System from within the Kaleidescape app.
•       When the user is finished with the Kaleidescape app, they can tap the Return button and a message appears containing an option to return to the controller app.
•       The user taps the popover option to return to the controller app.

The home control app must use the special URL in order to enable the Return button.  For help, refer to Integrating with the Kaleidescape App for iPad.

Kaleidescape Child Remote

When the Child Remote is used, the onscreen user interface automatically switches to the simplified child user interface, eliminating all text-based menus in favor of pure graphical navigation of movie covers.

In addition to the preprogrammed Kaleidescape Child Remote, the child user interface commands can be sent to any programmable controller. Refer to IR Control Hex Codes for Kaleidescape Systems or the Kaleidescape System Control Protocol Reference Manual.

Third Party Control Devices

Kaleidescape provides a wide range of templates, modules, and sample programs for control systems from several manufacturers.

Some manufacturers also provide templates, modules and IR libraries to control Kaleidescape systems.

Control devices can be simple IR remotes or touch panels.

IR Remote Control

The simplest control device is a generic IR remote control for a DVD player.

IR Code Sets

The Kaleidescape movie player supports two major infrared remote control code sets.

•       Code set used by Toshiba DVD players and other manufacturers including Philips, Magnavox, Zenith, Onkyo, and Marantz
•       Code set used by Kenwood DVD players

Types of Remotes

IR remotes (other than the Kaleidescape Remote) fall into the following basic categories:

•       Pre-programmed
•       Learning
•       PC Programmable

Pre-programmed Remotes

Pre-programmed remotes only require setting the remote to control a Toshiba or Kenwood DVD player. Custom buttons that jump directly to Kaleidescape menu selections are not available.

Learning Remotes

Learning remotes can be used two ways: as a general remote with a Toshiba or Kenwood code set, or set to accept (learn) Kaleidescape-specific commands from a device that can generate these commands (for example, the Kaleidescape Remote).

PC Programmable Remotes

PC Programmable remotes can support commands specific to the Kaleidescape interface and provide a more complete experience. The manufacturer provides software that allows the remote to be programmed via a computer. This type of programming often allows IR codes to be imported in hex format (usually copying and pasting the codes into a text box), or from a Philips CCF file.

For a list of all IR codes (in hex) or CCF format available from Kaleidescape, or for the CCF file, go to

Templates are available for download for RTI, URC, and Elan remotes. Kaleidescape is also included in IR code database libraries for URC, Logitech Harmony and Opus.

Touch Panels

Kaleidescape supports several variations of touch panel control, including:

•       Onscreen Display with Video
•       Onscreen Display without Video

Onscreen Display with Video

Onscreen Display with Video (OSD Video) displays the Kaleidescape onscreen display on the touch panel, along with other controls, by using a video window on the touch panel. Touching the video display makes selections or navigates menus. OSD Video provides the richest user experience and is the implementation suggested by Kaleidescape whenever possible.

User-added image

Onscreen Display without Video

Onscreen Display without Video (OSD No Video) provides supplemental information with text-based details for content. The touch panel replicates the details pages for movies while browsing the onscreen display.

User-added image

When selecting the touch screen for an installation, consider whether a video display is present and the technical capabilities of the touch panel. Installations can require more than one type of touch panel interface to provide the best control for every zone.
