The IQUPC31 provides two channels of multi-rate up conversion for SD-SDI digital video signals. Using high quality motion adaptive de-interlacing and flexible scaling technology the IQUPC31 is a broadcast quality conversion module ideal for space constrained installations, or for applications requiring simultaneous HD snd SD output feeds.
IQUPC31 includes frame synchronizers, capable of referencing to a SD bi-level or HD tri-level reference and independent variable aspect ratio converters with frame accurate reading and writing of WSS, VI and 2016 AFD signalling. Audio handling includes audio channel routing, delay adjustment and level controls. Video metadata such as timecode, closed captions and teletext captions can also be passed through the module or processed according to the required output standard.
To allow the module to be further tailored to system requirements software options are available to provide noise reduction and side-bar keying, and versions are available with SFP cages enabling fiber conversion, or additional electrical outputs on HDBNCs.
High-quality upconversion for SDI video inputs including conversion aperture control
Frame synchronizer with HD tri-sync/SD bi-level reference input and input loss detection
Aspect ratio conversion including preset ARC maps relative to conversion modes, selectable pan, tilt, aspect, size, and output crop adjustments
Aspect ratio control (signaling reading and writing) using ETSI WSS and AFD video index signaling (RP186, SMPTE ST 2016)
Video processing features include: gain, offset, hue, horizontal and vertical picture enhancement, and RGB gamut legalization
Metadata support — Closed caption passing or processing for CEA608/708, and WST/OP42 and OP47 teletext captions, and VITC or SMPTE ST 12 timecode translation
Built-in test pattern generator and 19 character scrolling caption generator
Additional processing options including; noise reduction (adaptive spatial and recursive), side-bar keying and linear frame rate conversion
Processing for 16 channels of embedded audio present on the incoming SDI stream with no disturbance during video synchronizer frame wraps or drops
Audio processing features including: channel routing, gain, invert, delay and 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
16x user memories
RollCall control and monitoring compatible with standard logging and reporting features
RollTrack triggers available for detected module states including: input loss/freeze and reference loss

Conversion Functions (per channel)
Aspect ratio conversion synchronization
Still process: Detects still images and applies an aperture with full (progressive) vertical frequency response
Enhanced still: Adds field motion detection to still process. Prevents artifacts on moving repetitive patterns
Aspect ratio conversion (manual or auto): AFD (SMPTE ST 2016), VI (RP186), WSS (L23)
