1 DEC-1023 12-Bit Composite to SDI Decoder
1.1 Introduction
The DEC-1023 is a high-quality composite analog video to SDI decoder designed for incoming feed
applications. This 12-bit decoder offers 2D and 3D adaptive decoding filters, video proc-amp functions, VBI
data processing, AGC, input validity and error detection reporting. A frame sync with TBC functions is
optional. When combined with one or multiple audio cards, an operator can select any of the audio channels
to embed into the SDI signal. Each audio output channel can be composed of a mix of any two audio input
channels. New technology includes Thumbnail & ALM (audio level meter) generation and an optional
Waveform/Vectorscope over IP of the output signal, which allows the operator to control and see the
changes made to the signal.
This card operates with the MSB-1121 Monitoring Switching Bridge which allows the output of any module in
the Densité frame to be monitored.
1.2 Features
• Composite analog video differential input with passive loop-through
• Up to five (5) SDI 4:2:2 digital video outputs
• Reference input with passive loop-through
• 12-bit A to D conversion with 2D and 3D adaptive decoding
• Video
processing control
• Ancillary Data Blanking or pass-through
• Automatic user calibration of components based on a known test pattern
• Built-in test signal (Full Field 75% Color Bars with 100% White)
• Audio embedding of 8 channels (when linked with audio card)
• Frame Sync Option provides timing, full phasing and freeze modes
• Thumbnail
generation
• Waveform/Vectorscope over IP option (operates with iControl)
• Provides output to Monitoring Switching Bridge option (MSB-1121)
• Cable equalization for up to 300m.
1.3 Probing option
The DEC-1023 Probing Option integrates several advanced features for monitoring of both video and
embedded audio signals. The Probing Option offers complete real-time measurement and analysis of an
extensive set of signal parameters, as well as flexible alarm thresholds and sensitivity. Once defined, the
DEC-1023 probing settings can be saved along with the rest of the card configuration, in five user-defined
profiles. Using iControl, the DEC-1023 Probing Option can conveniently and remotely be enabled and
configured, on existing Densité-Series DEC-1023 cards.
