IQMDA40 12G/3G/HD UHD-4K Down Converter & DA

The IQMDA40 also includes a 12G/quad-link SDI 4K UHD frame synchronizer and processing for the downcon­verted channels with powerful picture enhancement tools. High Dynamic Range and Wide Color Gamut support allows S-Log3, HLG or PQ 4K UHD feeds to be integrated into an SDR workflow.

A variable aspect ratio converter with reading and writing of WSS, VI and 2016 AFD signaling, video processor and legalizer are also included.

Audio handling includes channel routing, delay adjustment and level controls. Video metadata such as timecode, SMPTE ST 2020 Dolby, closed captions and teletext captions can also be passed through the module or processed according to the required output standard.

FEATURES
