    The IQDNC31 provides two channels of multirate downconversion for 3 Gb/s SDI and HD-SDI digital video signals. Using high-quality motion adaptive de-interlacing and flexible scaling technology, the IQDNC31 is a broadcast-quality conversion module ideal for space constrained applications requiring downconversion to maintain SD output feeds.

    IQDNC31 includes frame synchronizers, capable of referencing to a SD bi-level or HD tri-level reference and independent variable aspect ratio converters with frame accurate reading and writing of WSS, VI and 2016 AFD signaling. Audio handling includes audio channel routing, delay adjustment and level controls. Video metadata such as timecode, closed captions and teletext captions can also be passed through the module or processed according to the required output standard.

    To allow the module to be further tailored to system requirements software, options are available to provide noise reduction.
