The AJA D5D Decoder provides all digital decoding of analog NTSC/PAL or Y/C (S-Video) to SDI.
The D5D is useful for bringing video from time-base corrected analog composite equipment into a serial digital environment.
The D5D features a crystal PLL jitter filter/memory to reduce jitter in the SDI outputs. The D5D decodes the full dynamic range of input video. Values below black and above white are not clipped. In the NTSC mode, the removal of the 7.5 IRE pedestal can be enabled by external dip-switch selection.
