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.
High-quality downconversion for 12G-SDI quad-link 4K video inputs with conversion aperture control
12G single-link to 3G quad-link output mode with 2SI or square division format selection (also applies to quad-link inputs for SQD <> 2SI translation)
Frame synchronizer with HD tri-sync/SD bi-level reference input, and input loss detection with default output of black/pattern
Aspect ratio conversion including preset ARC maps relative to conversion modes, pan, tilt and size input crop adjustments
Aspect ratio control (signaling reading and writing) using ETSI WSS and AFD Video Index signaling (RP186, SMPTE ST 2016)
Video proc. features include: gain, offset, hue, horizontal and vertical picture enhancement and RGB gamut legalization
Wide color gamut support with BT709 and BT2020 color space conversion including manual and automatic operation
High Dynamic Range support including SDR to HDR mapping with enhancement, translation between HDR formats — PQ, HLG, S-Log3, and mapping to SDR
Metadata support — Closed caption passing or processing for CEA608/708 and OP42/OP47/WST captions, VITC or SMPTE ST 12 timecode translation
Processing for 16 channels of embedded audio present on the incoming SDI stream with audio proc. features including: channel routing, gain, invert, pair delay and internal tone generator
Non-PCM processing features pair level routing and delay compensation. Dolby-E data is passed with a delay to match the video and with co-timed audio frame drop or repeat
Dolby E support — Detection of PCM/non-PCM audio to SMPTE ST 337/338, pair routing and Dolby E header re-alignment
Integrated fiber I/O support via SFP module
Built-in test pattern generator and 16 user configurable memories
RollCall control and monitoring compatible with standard logging and reporting features
RollTrack triggers available for detected module states including input loss
4K UHD downconverter and DA with HDR support for 12G/QL-SDI signals. SDI input and output configurations based on processing mode selection, external or frame reference, single 12G capable fiber Tx/Rx

IQMDA40: 4K UHD SDI Downconverter & Distribution Amplifier Datasheet
The IQMDA40 is a 4K UHD quad- or single-link high-quality downconverter and distribution amplifier able to distribute a 12G SDI input to three outputs, while converting it for HD/SD simulcast or monitoring applications.
The IQMDA40 from Grass Valley, a Belden Brand, 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.
