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.

ASD-111i COMPONENT ANALOG VIDEO TO 4:2:2 CONVERTER

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.

Figure 3.3 CAV format selection

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.

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, +,

- push-buttons and the

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.

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 push-

button 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.

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 ASD-

111i, 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.

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.
