Instant Replay for Stereoscopic 3D Cameras
The following configurations of the Mira 8-Channel and Mira 4-Channel servers allow video channel pairs to operate as a Stereoscopic 3D
(3D) transport, with each paired transport having one RS422 serial control port.
Furthermore, the “3D ISO2” and “3D ISO3” video channel configurations respectively allow Mira to record two or three 3D cameras with
discreet L and R video signals into a single clip ID. An external control panel such as the DNF Controls “DMAT-AB” can then switch
between the two or three cameras on the replay channels during live instant replay operations.
With Mira configured for any “ISO” record operation, the set of record channels act as a single transport (ChA always controls all record
channels); the “ISO” inputs continuously record the input cameras without interruption—while the output channel(s) provide the live instant
replay playback.
If you wish to use Mira for “Stand-Alone” 3D operation (not instant replay), then please use the procedure “
” on page 179 above.
IMPORTANT NOTE:
The following tables detail the channel pairing for 3D channel configuration, with RS422 serial control. The shading
highlights channels that are paired together for 3D operation.
