Audio/Video
Synchronization Issues
Due to its extraordinarily high level of video processing performance, the DHD Controller
may distribute video signals with a perceptible level of audio latency. In order to easily
solve this issue, Runco recommends using the DHD Controller with a high-quality audio
receiver that has the ability to effectively synchronize audio and video signals.
Most mainstream audio receiver/switchers have the ability to synchronize the audio and
video to the Advanced Television Systems Committee (ATSC) prescribed tolerances.
According to the ATSC, the sound program should never lead the video program by more
than 15 milliseconds, and should never lag behind the video program by more than 45
milliseconds.
In addition, many A/V receivers introduce additional latency that needs to be
compensated for during the installation. Table 3-1 shows the amount of possible audio
latency given different signal input timings.
Do not store or transport the CineWall on its side! It should only
be placed on its side if absolutely necessary during loading and
unloading.
