properly.

If some point about the operation of this instrument is still unclear after you have read this
instruction manual, refer to the contact information on the back cover of the manual to contact
LEADER, or contact your local LEADER agent.
After you have finished reading this manual, keep it in a convenient place so that you can refer
to it when necessary.

This add-in software's features are only enabled after you enter a correct license key into the

For details on the STATUS (top screen), NOISE, LEVEL, BER, UTILITY, and SYSTEM settings,
see the LG 3810 instruction manual.

3.1 SOURCE

Press SOURCE under MENU to display the SOURCE screen.
Depending on the Source setting, the contents of the SOURCE screen differ, as shown
below.
See the following sections for explanations of the different screens. For an explanation of the
settings that are available when you set Source to Internal, see the LG 3810 instruction
manual.

Source = Fixed Pattern Source = PN

3. DETAILED SETTINGS

Source = External

Figure 3-1 SOURCE screen

● Explanation of function keys

• F3 Source

Select the TS input that you want to use.
Fixed Pattern: Videos and audio that are stored in the LG 3810 are

modulated and generated (factory default).
PN: PN23 or PN15 random signals are used.
External<Input:SPI>: The TS that is applied to the rear panel SPI input connector is

used.
External<Input:ASI>: The TS that is applied to the rear panel ASI input connector is

used.

3. DETAILED SETTINGS

Internal: A TS from the internal HDD or an external USB device is

used.

Notes regarding switching the source

• When the TS input is switched (between each fixed pattern, PN, SPI, ASI, and

Internal), the receiver lock is released momentarily to reset the encoding circuit.

• The LG 3810 cannot receive data if an external TS (SPI or ASI) is selected and the

TS IN alarm is lit on the top screen or a TS that exceeds the allowable rate for
encoding is applied.

3.1.1 Explanation of the SOURCE Screen (When Fixed Pattern is selected)

Set Source to Fixed Pattern on the SOURCE screen to display the following screen.

Figure 3-2 SOURCE screen (when Fixed Pattern is selected)

● Explanation of function keys

• F1 Pattern

Press to set the patterns that are stored on the LG 3810.

See section 3.1.2, “Explanation of the PATTERN Screen.”

3.1.2 Explanation of the PATTERN Screen

On the SOURCE screen, press F1 Pattern to display the PATTERN screen. You can use
this screen to set the video pattern, screen size, and audio pattern. You can specify any
combination of these settings.
F1 Pattern is available when you have set Source to Fixed Pattern on the SOURCE
screen.

● Explanation of function keys

• F2 Pattern

Select the video pattern.
Colorbar: An eight-color, full-field color bar is used (factory default).

3.1.5 Explanation of the TS SETTING screen

On the SOURCE screen, press F2 TS Setting to display the TS SETTING screen. You can
use this screen to set the null packet filter and PCR overwriting.

F2 TS Setting is available when you have set Source to External or Internal (only when
Format is set to MPEG-TS) on the SOURCE screen. When Source is set to Internal and a
TS file is being played back, you cannot switch to the TS SETTING screen.

Figure 3-6 TS SETTING screen

● Explanation of function keys

• F2 Null Packet Filter

If you set Null Packet Filter to On, packets that contain the 0x1FFF PID are filtered
from the TS that is applied to the LG 3810. Removing unnecessary null packets
provides you with an increased number of carrier modulation choices. This feature is
not available for broadcast transport streams.
[ Off / On

]

• F3 PCR Update

Converts the external TS to a broadcast TS for broadcast encoding. During this
conversion, because the LG 3810 carries out operations such as rearranging the
packet order and inserting invalid packets, the PCRs must be overwritten. Therefore,
normally set PCR Update to On. For each external TS, the LG 3810 can overwrite up
to 8 types of PCRs. This feature is not available for broadcast transport streams.

being played back from the internal HDD or an external USB device, the TS that is playing will
be stopped.

3.5 Sample TS

The LG 3810 comes with a USB memory device that contains an original sample transport
stream for checking the LG 3810's operations.

3.5.1 Notes

This TS has been created by LEADER to check the LG 3810's operations. It is not
designed to be used for evaluating decoders or as a reference for evaluating videos, image
quality, audio, or audio quality.
While the operation of this transport stream has been confirmed on representative
receivers that are commercially available, this does not guarantee that it will operate on all
receivers.
Please note that the data that is stored on the USB memory device can be deleted easily.

About the sample transport stream

• LEADER ELECTRONICS CORP. holds all copyrights to the videos contained in this
stream.

• You are not permitted to:

• Copy, process, or edit this stream without LEADER's permission.

• Decode this stream into a PES or elementary stream.

• Broadcast this stream or make it public for commercial purposes.

• Broadcast this stream or make it available to the general public.

• Transfer this stream to another company or individual.

• Use this stream with a device that has not been manufactured by LEADER.
