OVERVIEW

The 7735CEM 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 or AES inputs/outputs can be purchased with the encoder to create a video/audio
frame synchronizer/conversion package. In addition, Evertz fault monitoring processing will analyze and
report video and audio problems via an On-Screen-Display (OSD), or remotely via VistaLINK
The 7735CEM 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 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.
The features of all 7735CEM's are:
•
One component serial digital input (525 or 625).
•
EDH analysis on SDI input.
•
One composite analog video output WITHOUT OSD text or audio bargraphs.
•
Internal processing to maintain 10 bit digital video quality.
•
10 bit output video digital to analog conversion.
•
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.
•
One composite analog reference input (NTSC or PAL-B) on BNC. 75 Ohm or high-Z, jumper
configurable input impedance.
•
One frame video synchronizer (with +S option).
•
Infinitely variable output phase.
•
Freeze modes: black, freeze.
•
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.
•
Two GPI inputs are available to modify the display characteristics.
•
Two GPO output to indicate user definable fault conditions.
•
GPI/Os are available on a DB9 connector.
