IQUDC32

3G/HD/SD-SDI Up/down/crossconverter with AES I/O

Using high-quality motion adaptive de-interlacing and flexible scaling technology, the IQUDC32 is a broadcast-quality conversion module able to handle a wide variety of common applications such as upconversion for SD content repurposing on HD channels, or downconversion to maintain SD output feeds.

The IQUDC32 includes a frame synchronizer, capable of referencing to a SD bi-level or HD tri-level reference and a variable aspect ratio converter with reading and writing of WSS, VI and 2016 AFD signaling. Audio handling includes eight user-configurable AES inputs or outputs, audio channel routing, delay adjustment and level controls. Video metadata such as timecode, closed captions...

FEATURES

  • High-quality up/down/crossconversion including conversion aperture control
