For details on the STATUS, NOISE, LEVEL, BER, UTILITY, and SYSTEM settings, see the LG

3810 instruction manual.

3.1 SOURCE

For details on the TS FILE settings when Source is set to Internal, see the LG 3810

instruction manual.

Press SOURCE under MENU to display the SOURCE screen.

Figure 3-1 SOURCE screen

Explanation of function keys

• F1 Pattern

Press to select the video pattern, screen size, and audio pattern from those that are

stored in the LG 3810.

See section 3.1.1, “Selecting the Fixed Pattern.”

• 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.

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


5

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 Selecting the Fixed Pattern

On the SOURCE screen, set Source to Fixed Pattern, and then press F1 Pattern to select

the video pattern, screen size, and audio pattern.

You can specify any combination that you want for the pattern, screen size, and audio. The

monoscope becomes different specific patterns depending on the screen size. If you have

set Standard to J.83C on the CODING screen, you cannot specify a monoscope pattern

with a screen size of 1440×1080i.

The TS signals of the patterns that are stored in the LG 3810 support the standards that

you can specify on the CODING screen. Depending on the value that you have specified

for Standard, the number of selectable screen sizes changes.

See section 3.2.1, “STANDARD.”

Figure 3-2 PATTERN screen


• F2 Pattern

Select the video pattern.

Colorbar An eight-color, full-field color bar is used (factory default).

Ramp A full-field ramp is used.

Monoscope A monoscope is used.


6

• F3 Video Format

Select the screen size.

When Standard is DVB-C [ 720×576i / 1920×1080i ]

When Standard is J.83B [ 1920×1080i / 1280×720p / 704×480p /

704×480i (16:9) / 704×480i (4:3) ]

When Standard is J.83C [ 1920×1080i / 1440×1080i / 720×480i (16:9) /

720×480i (4:3) ]

• F4 Audio

Select the audio pattern.

1kHz(L,R) A tone signal (left and right both 1 kHz) is used.

400Hz(L,R) A tone signal (left and right both 400 Hz) is used.

1kHz(L)+400Hz(R) A tone signal (left: 1 kHz and right: 400 Hz) is used (factory

default). 3.1.2 Selecting the PN

On the SOURCE screen, if you set Source to PN, the LG 3810 generates a random signal

(PN23 or PN15).

Figure 3-3 PN selection screen


• F4 PN Pattern

Select the PN pattern.

PN23 PN23 (factory default)

PN15 PN15

• F4 PN Polarity

Select the polarity of the random signal.

Inverted The polarity is inverted.

Normal Error measurement using a general purpose BER measurement

instrument is possible (factory default).

• F4 Packet Type

Select the packet type.

Sync+PRBS Sync (47hex) + 187-byte PN (factory default)

Header+PRBS Sync (47 hex) + 1FFF (hex) + 10 (hex) + 184-byte PN

• F5 Item Select

Select the item that you want use F4 to set.

Depending on the selected item, the string displayed by F4 changes.

PN Pattern The PN pattern will be set (factory default).

PN Polarity The polarity of the random signal will be set.

Packet Type The packet type will be set. 3.1.3 Selecting EXTERNAL SPI or ASI

On the SOURCE screen, set Source to External to generate the TS that is applied to the

SPI or ASI connector.

Figure 3-4 External selection screen


• F2 TS Setting

Press to configure the TS input settings shown below.

You can also configure these settings when you use F3 Source to select Internal.

However, this only applies when Format is set to MPEG-TS.

• Null Packet Filter

• PCR Update

See section 3.1.4, “TS SETTING.”


8

3.1.4 TS SETTING

To display the TS SETTING screen, on the SOURCE screen, set Source to External or

Internal, and then press F2 TS Setting.

Figure 3-5 TS SETTING screen


• F2 Null Packet Filter

This setting is only available when you select an external TS (SPI or ASI) or the

Internal TS (MPEG-TS format). When turned ON, the Null Packet Filter filters packets

that contain the 0x1FFF PID from the TS that is applied to the LG 3810 input connector.

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 turn this setting 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.

[ Off / On ]

Notes regarding configuring TS settings

• You can only configure these settings when the TS input is SPI, ASI, or Internal.

However, if you have selected Internal, you can only configure these settings when

Format on the TS FILE screen is set to MPEG-TS.

• If you have specified Internal for the TS input, the LG 3810 will not display this screen

when a TS file is being played back.

3.2 CODING

Press CODING under MENU to display the CODING screen. Use this screen to configure the

modulation parameters.

Depending on the Standard that you have selected, the settings that you can configure on the

CODING screen vary as shown in the figures below.

Standard = DVB-C Standard = J.83B

Standard = J.83C

Figure 3-6 CODING screen

3.4.2 Program Code Details

This section will explain the program codes from section 3.4.1, “List of Program Codes”

that are unique to this option. For details on how to use GPIB and the program codes that

are shared with the LG 3810, see the LG 3810 instruction manual.

Function Selects or queries the broadcast standard

Syntax SY_n (setting and response)

SY_? (query)

r Audio Pattern

0 L: 1 kHz and R: 400 Hz

1 L and R: 1 kHz

2 L and R: 400 Hz

Example:

PN TS_0,0,1,0 (PN, PN23, Normal, Sync + PRBS)

ASI or SPI TS_1 (ASI)

Fixed Pattern TS_5,1,0,2 (Fixed Pattern, ramp, 1920×1080, 400 Hz)

Internal TS_3 (When performing a setting)

Response returned from TS_? 3,0 (internal HDD)

* You cannot specify a monoscope pattern with a screen size of 1440×1080. This setting

combination will be ignored.

* If the amount of data that follows the n parameter does not match what is expected for the

specified n value, the program code will be ignored.

* If the LG 3810 receives a “TS” command instructing it to set the transport stream while a TS is

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 original sample transport s

treams for checking the LG 3810's operations.

3.5.1 Notes

These transport streams have been created by LEADER to check the LG 3810's

operations. They are 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 these transport streams has been confirmed on representative

receivers that are commercially available, this does not guarantee that they 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 streams

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

streams.

• You are not permitted to:

• Copy, process, or edit these streams without LEADER's permission.

• Decode these streams into PESs or elementary streams.

• Broadcast these streams or make them public for commercial purposes.

• Broadcast these streams or make them available to the general public.

• Transfer these streams to another company or individual.

• Use these streams with a device that has not been manufactured by LEADER.
