7736CEM & 7736CEM-A4

Component SDI to Composite Analog Video Encoder with Optional Frame Synchronizer

Product ManualManual
  • 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 bar graphs
  • Internal processing to maintain 10-bit digital video quality
  • 12-bit output video digital to analog conversion
  • One monitoring quality video output with OSD text and bar graph graphics
  • User-adjustable output video processing functions: black level (brightness), gain (contrast), hue, and saturation
  • User-selectable luminance and chrominance filters for different applications (i.e. broadcast vs. studio)
  • User-selectable horizontal blanking interval width: narrow, normal
  • One composite analog reference input (NTSC or PAL-B) on BNC 75 watts 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
  • Built-in color bar generator
  • VU/PPM bar graph level Indicators
  • Decodes vertical interval time code (VITC) and "burns" the time code into the picture
  • Decodes PESA format Source ID (eight characters) or Evertz format VITC Source ID (five or nine 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 7800FC VistaLINK® Frame Controller module in slot 1 of the frame
  • Features of "-A4" version are:
  • One group (4 channels) of synchronous 20-bit audio is de-multiplexed from the incoming digital video
  • Two unbalanced AES audio inputs (up to 48kHz, 24 bits) on BNC terminal strip
  • 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
  • Four 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 five seconds
  • Additional audio advance of up to one frame, depending on video delay
  • Loss of video modes: pass audio, mute audio
  • Optional balanced AES audio inputs (+B option)
