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 will not playback smoothly in
the media signboard, likely due to storage I/O bottleneck.
Some JPEG images cannot be played in the signboard.
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. 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 (http://www.irfanview.com/).
The signboard 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 play list, just delete
the play list and restart signboard. The signboard 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. When nothing seems wrong,
the time zone setting is often the reason the program is not played.
