Installation

Folded Optics In rear screen applications where space behind the projector is limited, a mirror may be used to fold the optical path, as shown in Figure 3-5.The position of the projector and mirror must be accurately set. If you are considering this type of installation, contact your dealer for assistance.

Audio/Video

Due to its extraordinarily high level of video processing performance, the DHD Controller

Synchronization Issues

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 video displays and A/V receivers introduce additional latency that needs

 

to be compensated for during the installation. Table 3-4shows the amount of possible

 

audio latency given different signal input timings.
