Audio and
video are not
synchronized
If both the audio and video are being sent through the unit to the TV, be sure your firmware is fully updated, later
versions of firmware may have lip sync corrections.
If you are feeding the audio directly from the source into a distributed (whole house) audio system and not
through the ZeeVee unit, it will arrive to the speakers before the video arrives to the HDTV. This happens
because the video is being encoded into a digital signal, modulated by the unit and then demodulated at the
HDTV. Each of these steps adds latency that will not be reflected in the audio because it is traveling a shorter
path.
To work around the issue, you can try one of the following:
Use an audio delay device that allows you to add a delay to the audio stream before it reaches the sound
system.
Feed the audio to the ZeeVee unit and send it to the HDTV with the video. Then take the audio out from an
HDTV or external tuner (such as the ZvSync) and connect it to your audio system. The audio should have a
similar amount of delay since it has gone through the encoding and decoding process just as the video did.
IP Stream not
received and
displayed at
television
Check configuration parameters in Maestro. Check network parameters to make sure Ethernet switches are set
to locally forward multicast traffic (if employed). As a debug step, try connecting a PC running VLC directly to
the ZvPro Ethernet port and configure it to receive the stream.
