Includes SDI reclocked oututs, SDI out, compoisite preview, YUV out also. These are in box with back connectors so can be shipped in box or we can install in synpase frame for buyer. NOTE 1 card seems to have problem (doesn't power up correct) but 10 cards are perfect and workingThe ARC20 is a preset based broadcast quality aspect ratio converter. Itfeatures optimized conversion between different aspect ratios such as4:3, 13:9,14:9, 15:9, 16:9 and 21:9 with full 10-bit resolution (20-bitinternal). High quality vertical filtering is reached by using atemporal (3 field), 12-taps FIR filter. The aspect ratios can beswitched using WSS, VI, GPI or manual control. Input and outputs areSDI, 10-bit serial digital video (270 Mb). No genlock reference isneeded because the total delay of the ARC20 is fixed. An analog previewmonitoring output is provided with several comprehensive functions,including a scaling cage. This is the ultimate transmission environmentaspect ratio converter, with an extensive record of key-place usage.
