Appendix A FAQ
Even though the player conforms to leading industry standard video formats, some-
times the videos you acquire may fall outside the compatibility matrix.
If the files can play on your PC but not on your player, you should recompress the file
to ensure playback. For greatest compatibility, we recommend outputting high defini-
tion content to the WMVHD format (8Mbps bit-rate). You can recompress unplayable
video files with recommended file formats and 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.
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 DSA-2102 can be configured to automatically add black bars for certain types of
displays. You can set the output resolution in DSA-2102's browser configuration
page 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 compati-
bility.
JPEG images can be either of 2 types: baseline or progressive compression. Base-
line 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. Dedicated
devices using local storage 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 my media player support video streaming?
No, all media files are designed to play from local storage (HDD or internal CF card).
During content and schedule sync, contents are transferred to player°Øs local stor-
age 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 valu-
able "air time" and losing your audience's attention.
Could the media player be controlled by external input devices or interfaces?
No, unless specifically developed for.
Touch panel, bar code scanner, and motion sensors are popular input devices for PC
based digital signage media players, but RISC based players require considerable
effort to develop special hardware drivers for each I/O device.
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°Øs knowledge and experi-
ence with the specific media player. First check the on screen message and stats
