3.2 About KDS-MP4 Setup
To prepare the KDS-MP4 for operation, you need to:

  • Connect the machine, see Section 4 Connect the KDS-MP4 to play media; connect a USB keyboard to configure the KDS-MP4
  • Configure the machine, see Section 5 Before using the KDS-MP4 you have to configure it. When powering the unit, the machine boots up to the configuration mode if it does not recognize content for playback. At any point, configuration is possible when connecting a USB keyboard
  • Prepare the content and export Use the KDS-MP4 Manager to prepare the content to playback

4 Connecting the KDS-MP4

Always switch off the power to each device before connecting it to your KDS- MP4. After connecting your KDS-MP4, connect its power and then switch on the power to each device.
To connect the KDS-MP4, as illustrated in the example in Figure 3, do the following:

  1. Connect the HDMI connector to an HDMI acceptor (for example, an LCD display).
  2. Connect an amplifier to the 3.5mm mini-jack connector.
  3. Connect a USB mouse to a USB connector.
  4. If needed, connect a memory stick to a USB connector.
  5. Connect the Ethernet RJ-45 connector to the network via a LAN cable.
  6. Connect the power adapter to the 12V DC socket on the KDS-MP4 and to the mains electricity (not shown in Figure 3).

KRAMER KDS MP4 4K Digital Media Player  - Defining 02

If you need to configure the system (see Section 5), connect a USB keyboard to one of the USB connectors (see Figure 3).
The KDS-MP4 identifies only a true USB keyboard. A keyboard that is connected via a PS/2 to USB adapter is not identified.

Configuring the Player

This section describes how to configure the player.
5.1 System Connections
If KDS-MP4 is a media player, connect it to a monitor via an HDMI cable.
If it is a signboard (with built-in screen), no monitor is required. However, a signboard player can still be connected to a monitor via HDMI for larger display area.
When using an HDMI connection, audio is sent along with video over the HDMI cable, so no additional cables are required.

  1. Attach the AC power adapter to power on the unit. After approximately 15 seconds, the booting animation is displayed on screen as shown below:
  2. The boot-up process takes approximately 40 seconds to complete.

Troubleshooting Tips for media players The operation indicators light up, but no video is displayed on screen
Ensure that your video cable (HDMI) is securely connected. When using an HDMI connection, choose high quality, certified HDMI cables or try using shorter length cables
Check if your monitor is turned on and the correct video input source is selected

KRAMER KDS MP4 4K Digital Media Player  - button 15.19 Content Management
The player is designed to work with 3rd party management solutions. Refer to the printed guide for related set up instructions.
5.20 Authoring in HTML5
A major advancement in the player is the ability to playback HTML5 content, which can contain dynamic information. To find out more about using HTML5 for digital signage, visit www.KramerAV.com
5.21 Working with SMIL
The player uses open communications protocols for content presentation and playback control. SMIL-compliance means predictable results across multiple devices, and SMIL’s non-proprietary nature means that your investments are never obsolete.
5.21.1 Introduction check font
Using SMIL (pronounced “smile”), the language created by W3C for multimedia communications, the media player understands the language “spoken” by professional tools from companies such as Adobe, Apple, Microsoft, and Real Networks. What this means is quicker, easier, and better integration of your players into your digital signage networks, opening up avenues of software controls and realizing the full potential of your player hardware down the road.
5.21.2www.a-smil.org for developers
The media player operating system utilizes W3C SMIL as the underlying scripting language, which lends well to customization to your project management needs.
For resources, downloads, and community support, visit www.a-smil.org.

5.22 FAQ

What video format can I play?
Video files encoded in MPEG-4 AVC up to 1920×1080 resolutions and bitrates should play perfectly. If a certain video is not played as scheduled, or if it plays poorly, search the support site for “transcode” instructions.
What should I do if I forgot my password?
Perform a factory reset.
Use the S/W RESET button located at the back of the media player to restore factory settings. This also clears the player’s password.
How do I manage the playback of contents?
The media appliance is designed to be interoperable with leading 3rd party management software solutions or via SMIL open standard commands.
Can the player display Flash or Microsoft PowerPoint presentations?
The player features limited PowerPoint support, but not Flash support.
While PCs can play many formats with varying degrees of success, RISC-based media players are designed to reliably play specific video formats (see spec for details). While Microsoft PowerPoint native files cannot play directly on a RISC- based player, the file can be converted (i.e. Manager Express) into an image format to be played as an image slideshow.
Why won’t some media files play properly?
The video data bit-rate used may have exceeded the recommended bit rate.
The video data bit-rate is the amount of video or audio data used per second to store or play the contents, usually expressed in Mbps (mega-bits per second).
Video encoded with excessive bit-rates does not playback smoothly in the media player, likely due to storage I/O bottleneck.
Visit www.KramerAV.com for compatible media format presets.
The media playback looks different on a PC compared to the media player’s screen. (Wrong aspect ratio)
There are two major aspect ratios (width-to-height ratios) for video content, but many kinds of displays. If you play 4:3 video on a 16:9 display (or vice versa), a circle becomes oval, and the picture takes on a squeezed or stretched look. To avoid this distorted look, adding black bars is a common technique.
The Network Media Player can be configured to automatically add black bars for certain types of displays. You can set the output resolution in the player’s configuration menu to match the native resolution of your display.
Some JPEG images cannot be played in the media player. Progressive JPEG files are not supported. Convert to baseline JPEG for maximum compatibility.
JPEG images can be either of 2 types: baseline or progressive compression.
Baseline JPEG offers greatest compatibility, while progressive JPEGs are suitable for Web site images. Progressive images are downloaded and displayed “progressively,” being rendered more clearly as more data is received over the internet. Progressive images are primarily supported on PCs. For media appliances, make sure to save images as baseline JPEG in your photo editor, or resave them as baseline JPEGs using free tools such as IrfanView ( www.irfanview.com/ ).
Does the media player support video streaming?
No. Media players play files from local storage and do not support real-time video streaming over the network. This delivers an optimum viewing experience free of playback quality issues such as stuttering, blocking, or blue-screens.
The player is not playing. What should I do?
Play list errors and scheduling issues are two major causes of playback problems. To determine if the problem is caused by a bad playlist, just delete the playlist and restart the player. The player should loop through all media files, indicating a fault with the play list. If the playback is scheduled to play at specific time, check to see if the device is set to the right time zone on the world clock. If nothing seems wrong, the time zone setting is often the reason the program is not played.
The video is playing but I can’t hear any sound, what should I do?
Check volume (mute) settings on monitor.
