Explanation of function key

• 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). If Standard is set

to DVB-H, you cannot select this setting.
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.

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)

Figure 3-7 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.

3.5 Sample TS

The LG 3810 comes with a USB memory device that contains an original sample transpo
rt 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.
