1 ASD-231i NTSC/PAL to 4:2:2 Adaptive Decoder with TBC

L

1.1 Introduction

The ASD-231i is a multi-standard, fully digital, 12-bit decoder with 3D and 2D adaptive decoding
capabilities allowing optimal picture quality with virtually no cross-color or cross-luma artifacts. A
built-in Time-Base Corrector (TBC) supports unstable (VHS) inputs. The TBC mode offers an
auto decoding filter selection which automatically switches between comb and bandsplit filtering
on the luminance path only.

The ASD-231i offers the possibility of connecting a reference input for complete studio
integration; it synchronizes serial 4:2:2 video to a local reference input. If no external reference is
detected, the ASD-231i locks on to the composite input.

If the input signal degrades or disappears, the ASD-231i can be set to freeze on the last error­free field, switch to black, or disable the output 4:2:2 signals.

For those audio users requiring video delay tracking, a video processing delay signal provides
the ASD-231i input-output delay at all times.

The ASD-231i, with its built-in frame synchronizer and Automatic Gain Control supports stable,
unstable, and satellite inputs. All four 4:2:2 serial digital video signals respect the SMPTE 259M­C standard. Also, the serial digital video outputs carry EDH data according to the SMPTE RP165
standard. Additionnally, the ASD-231i has a built-in color bars test signal.

The ASD-231i is a member of the imaging family of digital video modules and therefore requires
the imaging Quartet, imaging Symphonie, or imaging Solo frame for mounting and power.

2.2 ASD-231i Mechanical Installation

The ASD-231i must be mounted within Quartet, Quartet-C, Quartet-M, Quartet-M-A75, Quartet­M-A110, Symphonie (using Symphonie-R-M rear module), or Solo imaging frames in order to
provide power to the module. This section describes how to install the ASD-231i in any of these
frames. It is not necessary to switch off the power from these frames when installing or removing
the ASD-231i.

2.2.1 imaging Quartet Series Frames

To install this module into Quartet, Quartet-C, Quartet-M, Quartet-M-A75 or Quartet-M-A110
follow these steps. For a closer look at module installation and removal, refer to the frame's
Guide to Installation and Operation.

1. Remove the frame's front panel by rotating the thumb screws counter-clockwise. Pull on the
handles.

2. Select an empty slot.

3. Carefully place the ASD-231i between a set of module guides and gently push the module
towards the rear of the frame until the module's edge connector is secured to the backplane.
Pull lightly on the module verifying that it does not move.

4. Replace the frame's front panel. Make sure to rotate the thumb screws clockwise in order to
secure it to the chassis.

2.2.2 imaging Symphonie Frame

To install this module into Symphonie follow these steps. For a closer look at module installation
and removal, refer to the frame's Guide to Installation and Operation.

1. Remove the front panel door by pulling on the door handles and gently lowering it.

2. Select an empty compartment.

3. Carefully place the module between the module guides and slowly push the module towards
the rear of the frame until the module's edge connector is secured to its rear module. A light
pressure to mate the connectors may be required. Pull lightly on the module verifying that it
does not move.

4. Replace the front panel door.

2.2.3 imaging Solo Frame

To install this module into Solo follow these steps. For a closer look at module installation and
removal, refer to the frame's Guide to Installation and Operation.

1. In order to remove the frame's front panel, gently pull on it.

2. Carefully place the ASD-231i between the module guides and gently push the module
towards the rear of the frame until the module's edge connector is secured to the backplane.
Pull lightly on the module verifying that it does not move.

3. Replace the frame's front panel.

2.3 Rear Panel Label

Connector labels have been shipped with the ASD-231i. These labels are to be installed on the
frames’ rear panel in order to identify the module's external connectors.

2.3.1 imaging Quartet Series/Solo Frames

To install the Quartet/Quartet-C/Quartet-M/Quartet-M-A75/Quartet-M-A110/Solo label, follow
these steps while referring to Figure 2.1.

1. Remove the screws associated with the ASD-231i connectors.

2. Carefully apply the label to the connectors.

3. Replace the screws making sure not to damage the label.
