    The IQDNC34 provides two channels of multirate downconversion for 3 Gb/s SDI, and HD-SDI digital video signals along with both composite and analog audio outputs suitable for monitoring applications where space is of the essence.

    IQDNC34 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 with audio monitoring outputs selectable from either video channel. 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.
