HIGH DEFINITION ISDB-T/TBMODULATOR
EN-206 I
1 INTRODUCTION
1.1
Description
The EN-206 I which allow audio/video signal input in TV distributions with
applications in home entertainment, surveillance control, hotel Digital Signage,
shops etc. It is an all-in-one device integrating MPEG4 AVC/H.264 encoding and
ISDB-T/Tb modulating to convert input signals to ISDB-T/Tb RF out in the
frequency range of 30~960MHz. The signals source could be from satellite
receivers, closed-circuit television cameras, blu-ray players, and antenna etc. its
output signal is to be received by ISDB-T/Tb standard TVs or ISDB-T/Tb STBs
etc.

Cascade Installation
EN-206 I unit has 1 TV signal to RF output encoded as ISDB-T/Tb Digital TV
signal.
Several EN-206 I units can be cascaded in order to increase the capacity. The
maximum capacity of a series of N units is 1xN incorporated TV signals. To
cascade 2 or more units, connect the RF output of the preceding unit to the TV
input (loop-through) of the next unit (see illustration).
Figure 7.

2 OPERATIONS AND MANAGEMENT
EN-206 I is controlled and managed through the keyboard and LCD display.
Figure 8.
►LCD Display:
It presents the selected menu and the parameter settings. The backlight in
the display is on when the power is applied.
►LED:
These lights indicate the working status.
Power: It lights on when the power supply is connected.
Alarm: It lights on when the there is error, such as the signal
source loss.
Lock: It lights on when the signal source is connected and goes
off when the signal is lost.
►Left/Right/Up/Down buttons:
Use these buttons to turn the screen pages, shift the target items by moving
the triangle, or change the parameter settings in the program mode.
