7736CEM & 7736CEM-A4

Component Video D to A with optional Frame Synchronizer, Audio Demux, and Audio DAC

VistaLINK® enabled

The 7736CEM line of component serial digital to composite analog video converters are broadcast quality encoders with an extensive list of additional features. An audio de-embedder with high quality audio digital to analog conversion can be packaged with the encoder to create a video/audio frame synchronizer/conversion package.

The 7736CEM product features various video processing functions such as VITC, closed captioning and SID extraction during the encoding process, as well as monitoring video for black and freeze conditions. The modules feature a clean (asynchronous) and a fast (synchronous) input video lock mode to handle upstream switches. The audio is processed, to extract level information for creating and displaying level and phase bar graphs. In addition, the audio is analyzed for periods of high level, silence, mono, and out-of-phase conditions. All of this status information is displayed on the monitoring analog output via on-screen display (OSD) overlay.

VistaLINK® enables remote monitoring, control and configuration capabilities via Simple Network Management Protocol (SNMP). This offers the flexibility to manage operations including signal monitoring and module configuration from SNMP enabled control systems (Manager or NMS) locally or remotely.

Features

  • One component serial digital input (525 or 625)
  • One re-clocked component serial digital output
  • EDH analysis on SDI input
  • Four composite analog video outputs WITHOUT OSD text or audio bargraphs
  • Internal processing to maintain 10 bit digital video quality

  • One monitoring quality video output with OSD text and bargraph graphics
  • User adjustable output video processing functions: black level (brightness), gain (contrast), hue and saturation
  • User selectable luminance and chrominance filters for different applications (ie. broadcast vs. studio)
  • User selectable horizontal blanking interval width: narrow, normal
  • One composite analog reference input (NTSC or PAL-B) on BNC. 75Ω or high-Z, jumper configurable input impedance
  • One frame video synchronizer (with +S option)
  • Infinitely variable output phase
  • Freeze modes: black, freeze
  • Input video lock mode: clean or fast
  • Adjustable free running frequency
  • VU/PPM bargraph level Indicators
  • Decodes vertical interval time code (VITC) and "burns" the time code into the picture
  • Decodes PESA format Source ID (8 characters) or Evertz format VITC Source ID (5 or 9 characters) and burns the ID into the picture
  • A comprehensive on screen display is available to configure the various features of the module
  • Flexible configuration of the text and audio bar graph information displays
    • An extensive list of error conditions can be monitored and fault conditions can be configured from these conditions
    • On screen messages can be triggered by the configured fault conditions
    • VistaLINK® capable for remote monitoring, control and configuration capabilities via SNMP; using VistaLINK® PRO, CP-2116E or CP-2232E Control Panels. VistaLINK® is available when modules are used with the 3RU 7800FR frame and a 7700FC VistaLINK® Frame Controller module in slot 1 of the frame
    • -A4 Version Features

    • User selects EITHER the de-embedded audio or the input AES audio
    • The selected audio is delayed equivalently to the video delay with the +S option
    • 4 high quality 24 bit audio channels are output (analog) as balanced on 2 removable barrier strips
    • Low impedance outputs (66Ω)
    • Analog audio output levels are adjustable
    • Additional audio delay of up to 5 seconds
    • Additional audio advance of up to 1 frame, depending on video delay
    • Loss of video modes: pass audio, mute audio
    • Optional balanced AES audio inputs (+B option)
