3.2 Input Status Monitoring

During automatic input detection (AUTO LED on), the following LEDs provide status

on the composite input signal. When forced mode is on (AUTO LED off), the

following LEDs indicate the selected format. For information on the various

detection modes refer to section 3.3, Input Detection Modes.

NTSC During automatic input detection, this LED turns on to indicate the

ASD-211i/2D has detected a NTSC composite signal connected to

NTSC/PAL IN.

PAL During automatic input detection, this LED turns on to indicate the

ASD-211i/2D has detected a PAL-B,G,H,I composite signal

connected to NTSC/PAL IN.

PAL-M During automatic input detection, this LED turns on to indicate the

ASD-211i/2D has detected a PAL-M composite signal connected to

NTSC/PAL IN.

PAL-N During automatic input detection, this LED turns on to indicate the

ASD-211i/2D has detected a PAL-N composite signal connected to

NTSC/PAL IN.

B&W The B&W LED, located within the set of INPUT LEDs, will turn on

when the ASD-211i/2D has detected a composite signal with no

color burst.

ERR The ERR (error) LED will turn on if no input composite signal is

installed. Also, if a standard is forced, say, PAL and the input signal

detected is other than a PAL signal, the ERR LED will turn on or it

may flash. Make sure the composite input signal is properly

connected to NTSC/PAL IN and verify for any source equipment

errors.

3.3 Input Detection Modes

The ASD-211i/2D supports two modes of detection: automatic input detection and

forced input selection.

3.3.1 Automatic Input Detection

During this mode of detection, the ASD-211i/2D detects the type of input and

automatically switches to that format by loading the decoder with the format’s

parameters. To enable automatic input detection, follow these steps:

1. From the main menu, press SELECT to enable the STD-INPUT menu.

2. To set automatic detection, use the UP(+) or DOWN(-) push-button to move to

the AUTO LED. Automatic detection is ready for selection when AUTO flashes.

3. Press SELECT to store the mode of detection.

4. To return to the main menu, press SELECT until there is no more flashing LED.

3.3.2 Forced Input Selection

This mode allows you to select one of the input formats. During this mode of

operation, the ASD-211i/2D remains configured with the format selected at all times

regardless of the input signal’s format. If the input signal’s format is other than that

selected, the ERR LED will turn on or it may flash. This feature is handy when you

are certain that the input format will not change. To select the forced input for

forced input detection, follow these steps:

1. From the main menu, press SELECT to enable the STD-INPUT menu.

2. To force an input format, use the UP(+) or DOWN(-) push-button to select

between NTSC, PAL, PAL-M, or PAL-N. During forced input selection, the

AUTO LED remains off.

3. Press SELECT to store the mode of detection and the forced input format.

4. To return to the main menu, press SELECT until there is no more flashing LED.

NOTE: During automatic input detection, if the input signal changes while you

are attempting to change the value of a menu function, the ASD-211i/2D exits

from the menu, returns to normal and attempts to locate the correct format.

However, the ASD-211i/2D will not exit the menu if an input format is forced.

3.4 Decoding Filter

The ASD-211i/2D provides several types of decoding filters, as shown in figures

below. The selection of the filter will depend highly on the nature of the input

composite video. Generally, optimal decoding is obtained with 3-line or 2-line filters.

For key and monochrome inputs, select 2-line and B&W filters respectively. The

simplest way to choose a decoding filter is to pass through each one and compare

their performances with the intended source.

Figure 3.3 NTSC decoding selection

Figure 3.4 PAL-B,G,H,I,M,N decoding selection

To select a decoding filter follow these steps:

1. From the main menu, press SELECT twice to enable the DECODING menu.

2. Use the UP(+) or DOWN(-) push-button to select the desired decoder. Figures

3.3 and 3.4 describe the decoder selection sequence for the NTSC and PAL-

B,G,H,I,M,N formats respectively.

3. Press SELECT to store the selected decoder for the current format.

4. To return to the main menu, press SELECT until there is no more flashing LED.

3.5 Automatic Input Calibration

The ASD-211i/2D can perform automatic input calibration reassuring properly

quantized 4:2:2 output signals. This is accomplished by monitoring the pixel value

within the region of the white bar of a color bars input signal. For a 100% color bars

input, the pixel value of white must be 940. If the ASD-211i/2D reads a value other

than 940, it will amplify or attenuate the input signal accordingly. It will repeat this

procedure until 940 is read. To perform input calibration follow these steps:

1. Install a 75% or 100% color bars signal to NTSC/PAL IN.

2. From the main menu, press SELECT three times to enter the CALIB menu.

During this time, the CALIB LED flashes.

3. Press UP(+) or DOWN(-) to begin calibration. The INPUT CALIB LED flashes

quickly as the ASD-211i/2D performs input calibration.

4. If the calibration is successful, the ASD-211i/2D automatically enters the SETUP

menu. To return to the main menu, press SELECT until there is no more flashing

LED. If the ASD-211i/2D failed to properly calibrate the input, the flashing rate

returns to normal and the menu remains in CALIB. Verify your installation and

make sure there is 75 ohm termination on the NTSC/PAL IN loop-through output.

Repeat step 3.

NOTE: The luminance and chrominance gains are reset to a gain of 1 after a

calibration execution. Also, the horizontal phase (position) is centered.

3.6 Setup

A setup range of -15 IRE to +15 IRE may be added to or removed from the input

signal in increments of 0.2 IRE. At all times, the selected setup should be equal to

the setup present on the input signal. When 7.5 IRE setup is selected, the 7.5 LED

is on and when a 0 IRE setup is selected, the 0 LED is on. However, both LEDs are

off if the setup is set to a value that is not 0 nor 7.5 IRE.

Follow these steps to set the setup:

1. From the main menu, press SELECT four times to enter the SETUP menu.

During this time, the 0 and/or 7.5 SETUP LEDs flash.

2. Use the UP(+) or DOWN(-) push-button to set the required setup. For a faster

3.10 V ANC Selection

Incoming vertical ancillary data can be manipulated in four possible ways. Refer to

Table 3.2 for a description of each possible setting and Figure 3.1 for the location of

the V ANC jumper.

Table 3.2 V ANC selections

Jumper position V ANC data

BLANK Incoming V ANC data is removed.

DECODE Incoming V ANC data is decoded.

BYPASS Incoming V ANC data is unprocessed and buffered to the luminance

channel only. Chroma data is set to 0.

USER Incoming V ANC data is modified according to the remote ICP-S

configuration. Refer to the ICP-S on-line help file for the ASD-211i/2D.

NOTE: Normally, V ANC should not be set to USER if there is no ICP-S

communication. However, you may use ICP-S to configure V ANC and download the

parameters to the ASD-211i/2D. This way, you may select USER (without ICP-S

communication) to load the V ANC parameters previously downloaded.
