Troubleshooting Tips
39
❏
Video only MPEG files played on the same channel as
MPEG files with video and audio data: Confirm that all
files on a particular channel are either video only, audio
only, or audio/video files. It is recommended to have a
"blank" audio track encoded with all MPEG files--even if
no audio is present on the source material. This allows
system flexibility when adding future MPEG files.
❏
The bit rate of the MPEG files being played exceed the
system capabilities: The Visual Circuit MPEG decoder
boards and digital servers all have a maximum sustained bit
rate that can be delivered. Refer to the system board and
specifications for information. Always, consult your Visual
Circuits representative prior to encoding or designing your
installation if there are any questions.
❏
Unequal elementary streams/uneven video or audio tracks.
Cross channel synchronization requires equal playback
duration and similar timecode starting points of MPEG
files: For cross channel sync all MPEG files must have
equal playback duration. If in a synchronized group of
channels, files vary in length, the driver will attempt to
synchronize these unevenly matched files and cause
"stuttering". It is also recommended to encode files with
equal bit rates whenever possible and files lengths that are
exact. Also the starting point of each MPEG’s timecode
must be the same.
NOTE
Using the timecode provided on the original
source type may not provide the same
timecode starting point for each MPEG file.
Consult your encoding manufacturer's
documentation for information on providing
the same start point for each MPEG encoded.
