The IQUDC40 is a flexible 4K UHD processing unit able to process and translate both quadrant (square division) and 2SI (2 sample interleave) quad-link formats as well as 12G-SDI single-link signals. Converting to or from 4K UHD to HD/SD allows re-purposing of existing assets, and all common video and audio processing tasks are also covered.
IQUDC40 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 (not available in 4K UHD to 4K UHD mode). Video processing includes powerful picture enhancement tools, including edge enhance, High Dynamic Range and Wide Color Gamut support allowing S-Log3, HLG or PQ UHD feeds to be integrated into an SDR workflow for example. 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 up/down/crossconversion for SDI video inputs including conversion aperture control and cadence insertion, detection and removal (e.g. 1080i/59 3:2 to 4K23)
4K UHD interfacing to translate between 2SI and square division workflows for maximum signal compatibility
Frame synchronizer with HD tri-sync/SD bi-level reference input, up to 8 frames of video delay 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 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, color corrector 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 scene-referred and display-referred conversions for SDR to HDR mapping with enhancement, translation between HDR formats — PQ, HLG, S-Log3 and mapping to SDR
3D user LUT loading with full support for BBC type I, II & III 1.4 version LUTs
Metadata support — Closed caption passing or processing for CEA608/708 and OP42/OP47/WST captions, SMPTE ST 2020 handling, VITC or SMPTE ST 12 timecode translation and SID passing including an ancillary data bridge to allow transfer of up to seven different ANC packet types around the converter
Processing for 16 channels of embedded audio present on the incoming SDI stream with no disturbance during video synchronizer frame wraps or drops
Audio proc features including: channel routing, gain, invert, channel 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 8 user configurable memories
RollCall control and monitoring compatible with standard logging and reporting features
RollTrack triggers available for detected module states including: input loss and reference loss
UHD-4K format converter with HDR support for quad link and 12G-SDI signals. 1 12G-SDI input with loop-through, 2 12G-SDI capable outputs, 4 3G-SDI input and outputs (selectable), external or frame reference, single 12G capable fiber Tx/Rx
