1 ASD-111i 4:2:2 Analog to Digital Converter

1.1 Introduction

The ASD-111i is a high-quality 10-bit analog to digital 4:2:2 video converter. A wide
range of component analog video (CAV) inputs are supported including GBR,
SMPTE/EBU, Betacam, and MII. Its microcontroller-based technology simplifies
switching from one standard to another. As an EDH inserter, the ASD-111i will insert
EDH Check Sum and Flag information into the outgoing serial signal. The ASD-111i's
powerful automatic calibration feature can accommodate a non-standard video or
correct a calibration defect in the incoming video signal. Factory set with 11 different
formats, all user configurations are stored in non-volatile memory for ease of use.
The ASD-111i's digital oversampling offers the best signal quality, while digital
processing eliminates the need for analog adjustments. A total of three 4:2:2 serial
digital video outputs are supplied; all 4:2:2 outputs conform to the SMPTE 259M
standard.

The ASD-111i is a member of the imaging family of digital video cards and therefore
requires the imaging Quartet, Quartet-C or Quartet-M, imaging Solo or imaging
Symphonie housing frame for mounting and power.

3.2 Line Format Status and Error Detection

The following indicators provide information on the ASD-111i's line format status.
Refer to Figure 3.1 for the correct indicator location.

• 525

This LED lights up to indicate the ASD-111i has detected a CAV input with a 525
line format.

• 625

This LED lights up to indicate the ASD-111i has detected a CAV input with a 625
line format.

• ERR

This LED lights up to indicate that no sync is being detected. During this time,
the corresponding 525 or 625 line format LED indicates the last valid format. At
all times, make sure that all CAV input signals are firmly installed and that source
equipment is functional. Also, depending on your installation, make sure the
ASD-111i is properly configured for external or sync-on-green synchronization.

3.3 Input Signal Format Selection

The ASD-111i must be informed on the type of CAV input installed. The choices of
CAV inputs, as they successively appear when scrolled through, is shown in Figure

3.3 below. In order to program the appropriate format, use the FORMAT push-button
to scroll through the choices of CAV inputs. In more detail, follow these steps.

1. The current CAV format programmed for the ASD-111i is indicated by the status
of its corresponding LED. The list of LEDs are GBR, SMPTE, BETA, MII and
SETUP. Press the FORMAT push-button to select the next available CAV
format. Use Figure 3.3 as a guide.

2. After each key press, a new CAV format with or without setup is selected. If, for
instance, the SMPTE/EBU format is selected and FORMAT is pressed, then the
BETA LED will turn on and the ASD-111i will be programmed to receive a
Betacam signal without setup. One more key-press will program the ASD-111i
for Betacam with setup. When a format with setup is chosen, the yellow SETUP
LED will turn on.

3. Whenever power is removed from the ASD-111i, the CAV format programmed
prior to the removal of power is recorded. This recorded CAV format is used
when the ASD-111i is re-powered.

3.4 Automatic Calibration with Error Status

The automatic calibration function adjusts the gain and offset levels of the input CAV

signals in order to conform the output 4:2:2 serial digital signal to the SMPTE 259M
standard.

The ASD-111i executes automatic calibration by searching distinct areas in the video

signal for proper sampling. For this reason, it is highly recommended that a 75%,
100%, or SMPTE color bars test pattern be installed whenever performing automatic
calibration. Follow these in order to execute automatic calibration.

1. Install a 75%, 100%, or SMPTE color bars test pattern in the required video
format. If these test patterns are not available, ensure that the input signal has
yellow, cyan, and black situated in the zones as indicated in Figure 3.3.

2. Use the FORMAT push-button to select the video format being processed.

9

3. Depress the CALIB. push-button for more than 2 seconds in order to execute
automatic calibration. For several seconds, the ASD-111i will attempt to conform
the output 4:2:2 signal to the SMPTE 259M standard. During this time, the ERR
calibration LED will flicker. The flickering will stop automatically after a complete
and successful calibration. Both offset and gain levels for the current format are
automatically stored.

4. If a particular parameter of the signal could not be calibrated, it will be indicated
by the ERR LED and the manual calibration LEDs. For example, if automatic
calibration failed to properly adjust Y gain, then the Y GAIN LED will be lit. Press
any push-button in order to cancel automatic calibration. No offset or gain levels
for the current format are stored.

3.5 Manual Calibration of Gain, Offset and Horizontal Centering

The manual calibration interface consists of the SELECT, +,
Y GAIN, Y OFST, B-Y GAIN, R-Y GAIN, and H CENTER LEDs. The list of

adjustable parameters include G/Y offset, gain for G/Y, B/B-Y, and R/R-Y, and
horizontal centering. When a parameter is selected, its corresponding LED lights up.
After manual calibration is enabled, a 1 minute delay with no push-button selection
will automatically disable manual calibration. However, any changes made are
stored.

To manually calibrate the ASD-111i refer to the following steps.

- push-buttons and the

10

1. Make sure the ASD-111i is programmed for the type of input CAV signal being
processed. Use the FORMAT push-button to make any modifications. Refer to
the note following this procedure.

2. Depress the SELECT push-button. The Y GAIN, B-Y GAIN and R-Y GAIN LEDs
light up. Using the +/- push-buttons, a grouped gain calibration can be
performed.

3. Depress the SELECT push-button. The Y GAIN, B-Y GAIN and R-Y GAIN LEDs
turns off and the Y GAIN LED lights up. The +/- push-buttons may now be used
to adjust the output G/Y gain.

5. Depress the SELECT push-button. The Y GAIN LED turns off and the Y OFST
LED lights up. The +/- push-buttons may now be used to adjust the output G/Y
offset.

6. Depress the SELECT push-button. The Y OFST LED turns off and the B-Y
GAIN LED lights up. The +/- push-buttons may now be used to adjust the output
B/B-Y gain.

5. Depress the SELECT push-button. The B-Y GAIN LED turns off and the R-Y
GAIN LED lights up. The +/- push-buttons may now be used to adjust the output
R/R-Y gain.

6. The next parameter to be adjusted is horizontal centering. Horizontal centering
is the timing difference between the active video and the horizontal sync.
Depress the SELECT push-button. The R-Y GAIN LED turns off and the H
CENTER LED lights up. Use the +/- push-buttons to adjust the horizontal
centering which has an adjustment range of -8 to +6 pixels by steps of
approximately 1 ns. Alternatively, depressing and holding the FORMAT push­button while using the +/- push-buttons allows to make steps of 1/2 pixel.

7. Depress the SELECT push-button once again in order to store the new changes
and to disable manual calibration.

Note: You cannot adjust the Y GAIN for a format with setup if you do not have a

75%, 100%, or SMPTE color bars input CAV signal. This is due to the
fact that during manual calibration of the Y GAIN an automatic black level
correction is performed and therefore requires a signal with the correct
sampling zones. Refer to Figure 3.3. However, this constraint is not
applied when a non-setup format is employed because the automatic Y
OFST correction samples in the blanking region.

3.6 Recalling Default Values

In order to recall default values of the current video format make sure you are out of
manual calibration mode. Then, simultaneously press the +/- push-buttons. This
action will erase any changes made to the parameters by the user and recall the
default factory-set parameters. However, this procedure does not recall the H
CENTER parameter.

11

In order to recall the default value of the H CENTER, you must enable manual
calibration by depressing the SELECT push-button until the the H CENTER LED
lights up. Finally, depress the +/- push-buttons simultaneously. This action will
erase any changes made to the the H CENTER parameter by the user.

3.7 Vertical Ancillary Data Masking

Any vertical ancillary data found on the CAV input signal lines listed in Table 3.2 may
be masked by the V ANC jumper. Perform the following steps in order to mask
vertical ancillary data or to allow it to pass through the ASD-111i.

1. Locate the V ANC jumper situated on the left side of the ASD-111i (refer to figure

3.2 for location).

2. To buffer through any vertical ancillary data set the jumper in the ON position. To
mask vertical ancillary data set the jumper in the OFF position.

3.8 Sync Selection

The ASD-111i can be synchronized to external equipment using an external
reference signal or sync information on the G/Y CAV input. In order to select
between the two modes of synchronization, refer to the following steps.

1. Locate the SYNC jumper (LK1) situated at the top right corner of the module
(refer to figure 3.2 for location).

2. If you are planning to use the studio reference signal to synchronize the ASD­111i, set the jumper in the REF position. Make sure the studio reference signal
is connected to the REF IN connector on the rear panel.

3. In order to synchronize the ASD-111i to the G/Y CAV input signal set the jumper
to the G position. Make sure the G/Y input signal contains sync information.

3.9 Coring Selection

Coring reassigns any digital data points situated about the blanking level of the B/B-Y
and R/R-Y inputs, which do not have exact blanking levels, to true blanking levels.
This prevents any unwanted color modulation throughout the video signal during
reconstruction of the 4:2:2 output into NTSC or PAL.

12

1. Locate the CORING jumper (LK2) situated on the left side of the ASD-111i (refer
to figure 3.2 for location).

2. To enable the coring function set the jumper in the ON position. In order to
remove the coring effect, set the jumper in the OFF position.
