I am setting up one 4D cinema with an DSS200 server.We always use the LTC output to sync the Film and 4D effects. All the server LTC output I used before this server all work well without any setting for LTC.But this time the server seem do not send the LTC signal.Does it need some setting to enable it?
FYI:I have measure the LTC output voltage,only 0.1V.Seemed it should be about 0.5V

What version software are you running on the DSS200? Also, have you contacted Dolby?

Steve，the system version is 4.3.5.9
Dolby engineer are not sure about this but give the advise to update the system.

Already update server to 4.6.1.Still the same. [Confused]

LTC should be working since 4.3.5.7...additional frame rates were added in 4.7.0.42. I don't work with it but that is from the release notes. There is no mention of having to activate it.

I'd definitely consult with Dolby on this one.

If HDMI is the golden standard, why it hasn't replaced all the existing professional video standards on the planet?

If you ask video prefessionals, I think they'll tell you that HDMI is not a professional connection, and they hate it with a passion. Mostly, it must be admitted, because of HDCP, which is the bane of vidiots lives. And HDMI doesn't travel well, HDMI cables are short, and to get an HDMI signal over any sort of distance it needs to be electrically converted to something else.

Ethernet might be a bit of a special beast, but that doesn't automatically disqualify it. While most of those interconnection technologies allow you to use TDM channels between devices, Ethernet only supports packets as its lowest addressable transmission payload.

There are audio technologies (AES50, HyperMAC) that use the Ethernet MAC layer protocols but not the normal Layer 2 upwards withernet stuff. Thus the manufacturers and end users have access to all the (relatively) low cost ethernet compatible stuff like chipsets and wiring standards.
