IQUDC30
Single Channel 3G/HD/SD-SDI Up/Down/Crossconverter
Using high-quality motion adaptive de-interlacing and flexible scaling technology, the IQUDC30 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 IQUDC30 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 audio channel routing, delay adjustment and level controls. Video metadata such as timecode, SMPTE ST 2020 Dolby, closed captions and teletext captions can...

FEATURES
