AJA D5D NTSC/PAL To Serial Decoder User Manual — Introduction Introduction The D5D Serial Digital Decoder provides low-cost all-digital decoding of analog NTSC, PAL or Y/C (S-Video) to 4:2:2 component serial digital. When working in a serial digital environment, the D5D is useful for bringing in video from time-base corrected analog composite equipment. The D5D provides three 4:2:2 component serial digital outputs.
I/O Connections Composite or Y/C Inputs Serial Digital Output 1 Configuration Determined by DIP switch on other side of Converter Serial Digital Output 2 + 5VDC Power Input Serial Digital Output 3 D5D, Side View User Controls The user interface for the D5D is a 4-position DIP switch accessible through a cut-out in the bottom of the unit. Use the DIP switches to configure inputs for Y/C or Composite, set blanking and pedestal, and configure the comb filter.
AJA D5D NTSC/PAL To Serial Decoder User Manual — Installation Switch 3—Configure Pedestal For Composite/Sync BNC : ON OFF 7.5 IRE pedestal for NTSC No pedestal (for inputs without Pedestal) Switch 4—Configure Comb Filter : Input Selection Matrix (2 BNCs) ON OFF Selects a three line adaptive comb filter (one line plus a 1.5us delay) Selects a two line non-adaptive1comb filter (1.5 us delay) The following table shows the combinations of DIP switch settings required to configure the two input BNCs.
