PowerPoint native files could not play directly on a RISC-based player, the file is converted through
other software (i.e. Signage Manager Express) into an image format to be played as an image
slideshow.
Why won’t some media files play smoothly?
The video data bit-rate may be higher than 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
will not playback smoothly in the media player, likely due to storage i/o bottlenecks. You can try
recompressing unplayable video files at lower bit rates using the free and open source Handbrake
tool at http://handbrake.fr/. Once you have found the right output settings for size and quality, save
them in Handbrake profiles for future use. Then you can easily recompress any unplayable files you
encounter in the future.
Why won’t some media files play at all?
Despite our best efforts to adhere to video format standards, video compression introduces many
variables, and sometimes the videos you acquire may not be playable on all players. In this case, you
should check your compression settings (bitrate, audio codec, and other parameters) and use a
compatible setting.
If the files can play on your PC but not on your player, you should re-encode the file to ensure
playback. For greatest compatibility, we recommend outputting to the WMV format (VC-1 codec, 3
to 5 Mbps bit-rate) using Windows Live Movie Maker, available free from Microsoft for Windows
Vista PCs. Simply drag your file into the Movie Maker timeline, then choose Save Movie As a 720p or
1080p video file to begin the re-encode. If you are using Windows XP or creating a video for the
NMP-200U, please use any of the available free or commercial video editing products for best results.
The media playback looks different on a PC compared to the media player’s screen. (Wrong
aspect ratio)
There are 2 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 are 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 NMP-550 ’s configuration menu to match the native
resolution of your display.
Some JPEG images cannot be played in the media player.
Progressive JPEG are not supported. Please 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. Devices with local storage such as the CF/Network Media Player are usually
incompatible with the latter type. Make sure to save images as baseline JPEG in your photo editor,
or resave them as baseline JPEGs using free tools such as Paint.net (http://www.paint.net/).
Does the media player support video streaming?
No, all media files are designed to play from local storage (HDD or CF card).
During content and schedule sync, contents are transferred to player’s local storage before being
presented on screen. This ensures the best possible presentation and fluid delivery of your video
message. Video streaming raises many playback quality issues such as image freezing, blocking, or
blue-screens, costing you valuable “air time” and losing your audience's attention.
The media player is not playing. What should I do?
Check the player’s messages on the display (OSD, or on screen display) for status information.
Since RISC-based media player usually lack input devices such as keyboard or mouse like PCs,
troubleshooting is usually based on user’s knowledge and experience with the specific media player.
First check the on screen message and stats reports. Bad play list and timing issues are two major
causes of playback problems. To determine if the problem is caused by a bad play list, simply delete
