The IQDNC34 provides two channels of multi-rate down conversion for 3Gbps SDI, and HD-SDI digital video signals along with both composite and analog audio outputs suitable for monitoring applications where space is of the essence.
IQDNC34 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 signaling. Audio handling includes audio channel routing, delay adjustment and level controls with audio monitoring outputs selectable from either video channel. 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 down conversion for SDI video inputs with composite 12-bit encoded and analog audio monitoring outputs
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 (signalling reading and writing) using ETSI WSS and AFD Video Index signaling (RP186, SMPTE 2016)
Video proc. 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 SMPTE12M timecode translation
In-built test pattern generator
Additional processing options including; noise reduction (adaptive spatial and recursive) and side-bar keying
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, 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
