Instant Replay for Normal 2D Cameras
The following configurations of the Mira 8-Channel and Mira 4-Channel servers allow video channels to operate with “Normal 2D cameras”
(meaning non-3D cameras) record/play transports for use during live instant replay applications. Each replay playback transport will have
one RS422 serial control port. The camera input record channels also have their own RS422 serial control ports, but they are not used
during live instant replay—only the replay channels require RS422 serial control.
Furthermore, the “ISO2,” “ISO3,” “ISO4,” “ISO5” and “ISO6” video channel configurations respectively allow Mira to record two, three, four,
five, or six normal 2D cameras into a single clip ID—with anywhere from two to six video “tracks.” An external control panel such as the
DNF Controls “DMAT-AB” can switch between the input camera tracks on the replay video channels during live instant replay operations.
With Mira configured for any “ISO” record operation, the set of two to six 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.
