[. . . ] 8995DNC Downconverter and Frame Sync Key Features ·High-quality downconverter with synchronizer for robust signal handling ·Image enhancement and pixel-level motion adaptive conversion for superb picture quality ·Full video proc. amp functions, including RGB and component color controls, video gain, chroma gain, phase control (hue), Y/C White and Y Black clip level controls, and color space conversion (ITU 601, ITU 709) ·Embedded audio can be adjusted for gain, delay, channel pairing, and output processing, then re-embedded into the video output stream ·Minimum delay (1 frame conversion) for low-latency live applications ·Maximum adjustable delay up to 9 frames ·Fiber-ready ­ accepts an optional SFP fiber device providing optical inputs or outputs ·Optional genlock reference input submodule for reference timing that supports loop-through, Tri-level sync and color black 53 Applications The 8995DNC is a compact, broadcast-quality fiber-ready downconverter. [. . . ] PCM audio processing eliminates the clicks caused by the video synchronizer dropping or repeating frames. This module silences the effects of hot upstream video switching using a V-fade. VITC and closed caption conversion are supported for same frame-rate downconversions, making this an ideal module for playout applications. One of three types of optional SFP fiber optic submodules can be installed in the fiber optic rear cage connector to provide two fiber inputs (Dual Receiver), two fiber outputs (Dual Transmitter), or one fiber input and one fiber output (Transceiver). Refer to the module pinout and block diagram on the next page. ·Where incoming feeds may be in either 1080 and 720 HD video formats ·For live production where low latency conversion is required ·For conversion of signals with embedded audio ·Incoming lines ingest of any signal format into an HD system, including synchronization conversion and proc. amp adjustment Specifications Supported Frame Types GeckoFlex with 8900NET (Net Card) for configuration Ordering Information Synchronizing mode = in minimum delay mode (synchronous input): Nominal: 1 frame (±1 pixel) User-adjustable range: 1 frame to 2 frames minus 5 lines Additional adjustable delay: 0 to 6 additional frames This module can be mounted in a GeckoFlex frame but not in other 8900 series frames, including Gecko-A or Gecko-V frames. As this module has no card-edge controls and in order to configure this module an 8900NET (Net Card) Network Interface module is required.
