Using Vidserve, check the box titled COLOR BARS and
observe if color bars appear on the output.
First, ensure that the cable or breakout box is plugged in
properly and that the video and audio outputs are plugged in
correctly to the display device. Try testing another channel
of the server on the same display. Try using other cables or
breakout boxes.
Verify the jumpers on the board.
Note that the output of the decoder board will not display on
a PC monitor.
Irregular playback on single and multiple channels can be caused
by a number of conditions:
Uneven audio to video track lengths: Confirm the length of
the audio track to the length of the video track. The Visual
Circuits VCC4PRO driver, standard with all Visual Circuits
boards and digital servers, aggressively synchronizes the
audio and video data of the MPEG file to maintain Audio/
Visual (AV) Sync. If the MPEG file's audio and video
tracks are uneven in length, the driver's attempt to
synchronize these uneven tracks will result in poor
performance. Mismatched AV track lengths will result in
overall degradation of system performance. Often a "bad"
file will cause uneven or stuttering playback on other
channels of the system as well.
