1. A SimulRecord operation also known as transfer while record involves recording of media and transferring of the same over the network From an AirSPACE system perspective 1 SimulRecord is a two stream operation a record and a transfer For instance if you have three SimulRecord operations in progress using DV25 media the AirSPACE cannot reliably process any other play or record channels at the same time For DV50 equal to twice the rates of aDV25 stream if you have two 2 SimulRecord or SimulPlay operations in progress you cannot play or record any other channels at the same time If the number of SimulRecord or SimulPlay operations or any stream combination is more than the specified number a streaming error may occur resulting in the SimulRecord operation being terminated If the number of SimulPlay operations is more than the specified number the play out may be staggered and audio loss may occur The SimulPlay stream must play out at real time speed e Minimum Clip Length 5 seconds gt 5 seconds when back to back play out e Realtime streams 8 DV25 6 DV50 IM X e SimulRecord SimulPlay operations 3 DV25 2 DV50 IMX Future software versions may present different operating parameters and performance Read each software version s release notes for the latest updates Contact your Avid Sales representative if you have any configuration related questions User Interface The metadata handling by AirSPACE can2. e The Ethernet port located on the Single Board Computer does not comply with FCC regulations If it is to be used it will require 2 ferrite beads attached to the RJ 45 M anufacturer Ferrite Bead M odel Number Fair Rite 0443164251 Fair Rite 0461167281 To purchase ferrite beads contact Forbes Engineering at 978 777 9100 e Taiwan EMC Regulations BSMI Class A EMC Warning ELPA S HEP RATA ALERARERP i Ay VRPT ReATH Aunan FF QAFTHELRRL ARE HG Conversion to IMX or back to DV e f changing A CVs between IMX and DV format is done incorrectly the system will not boot due to incompatible programming between the cards When hardware is upgraded to from IM X DV ACV cards different codecs are changed the format must also be changed otherwise when the system boots it cannot program the l O card dueto a format mismatch and becomes an inoperable system Follow these steps to ensure a successful transition to from a new IM X DV format 1 Goto the Setup menu 2 Select the Media Format screen 3 Select the new format to match the new ACV cards 4 Savethe format this will reset the UI and the system will not boot until the new cards are installed 5 You must now power off the system replace the I O ACV cards 6 Power on If you are still having problems or missed a step you may need to follow these additional steps Stop the framework by pressing Enter when it prompts you to do so Login to theAi
