SD4260 series products are ClearView’s all-in-one devices which integrate encoding,
multiplexing and modulation to convert V/A signals into digital RF output. SD4260
is also equipped with 1 ASI input for re-mux, and output with 2 ASI ports and 1 IP port.
The signals source could be from satellite receivers, closed-circuit television cameras,
Blue-ray players, and antenna etc. Its output signals are to be received by TVs, STB
and etc with corresponding standard.
With its various inputs available, our SD4260 series products are widely used in
public places such as metro, market hall, theatre, hotels, resorts, and etc for advertising,

monitoring, training and educating in company, schools, campuses, hospital… It’s a

good choice to offer additional info channels..

 4x S-Video/YPbPr/CVBS inputs; 1x ASI input for re-mux; 1x RF input for mix

carefully check before running.

2.5 Grounding Requirement

 All function modules’ good grounding is the basis of reliability and stability of devices.

Also, they are the most important guarantee of lightning arresting and interference
rejection. Therefore, the system must follow this rule.

 Grounding conductor must adopt copper conductor in order to reduce high frequency

impedance, and the grounding wire must be as thick and short as possible.

 Users should make sure the 2 ends of grounding wire well electric conducted and be

antirust.

 It is prohibited to use any other device as part of grounding electric circuit
 The area of the conduction between grounding wire and device’s frame should be no

less than 25 mm2.

output the corresponding program)

3) Modulator Setting

 Bandwidth

There are three possible options provided for selecting bandwidth: 6M, 7M, and 8M.
When the display shows them, user just need swift LEFT and RIGHT key to choose
and repressing ENTER to confirm.

When entering “Modulator” submenu, user can configure the modulating parameters
for the 1 carrier output separately:

Page 8

SD4260 S-Video/CVBS/YPbPr to DVB-T Encoder Modulator User Manual

 Constellation

Four different constellations QPSK, 16QAM and 64QAM will be shown on the LCD
window. User can set constellation type with the same method mentioned above.

 Transmission Mode

When user enters Transmission Mode, the LCD would show the current working
mode. User can move LEFT/RIGHT keys to select and press ENTER key to
confirm. 2K and 8K are the options:

2K: When the device works as current mode, the number of current carrier is 2048
8K: When the device works as current mode, the number of current carrier is 8192

 Guard Interval

In communications, guard intervals are used to ensure that distant transmissions do not
interfere with each other. These transmissions may belong to different users (as in
TDMA) or same user (as in OFDM). The purpose of the guard interval is to introduce
immunity to propagation delays, echoes and reflections, to which digital data is
normally very sensitive. There are four possible options provided to be selected. They
are 1/4, 1/8, 1/16, 1/32. User can shift the LEFT/RIGHT keys to select and press
ENTER to confirm.

 RF Frequency

The RF output frequency range is from 30 to 999MHz with 1K stepping. After
entering the RF frequency setting submenu, users the can press LEFT, RIGHT,
UP, and DOWN buttons to adjust the frequency and confirm by press ENTER
button.

 RF Out Level

The RF attenuation range is from -30~-10dbm (77~97dbµV) with 0.1db step.
After entering this setting submenu, user can shift UP/DOWN/LEFT/RIGHT
key to set the output level and press ENTER to confirm.

 RF On

This interface is to decide whether to enable the RF (carrier A) output or not.

OFF: to disable programs to output through carrier A.
ON: to enable programs to output through carrier A.
