Images stop in applications that
support High bandwidth NDI
• When a personal computer and this unit are connected via a commercially
available USB LAN conversion adaptor, the images may stop due to network
problems on the personal computer side.
→ If this phenomena occurs, firstly disable the network adaptor that is connecting the
personal computer to this unit, then change [Streaming mode] in [Video over IP] to
[H.264]. After this, re-enable the network adaptor that you disabled and the images
will be output when you change the [Streaming mode] to [High bandwidth NDI].
