1. Introduction
BR-101E can serve as a repeater, bridge or gap filler for DVB-T application. The
transmitted (target) channel’s configuration can be either the same or different as the
received (source) channel’s. The flexibility makes BR-101E a handy converter for
frequency, bandwidth, and modulation conversions between the received and
transmitted channels.
Basically, BR-101E receives a DVB-T channel, demodulates it to transport
stream (TS), re-modulate to DVB-T, and transmit to a new DVB-T channel.
BR-101E has built-in 31-way PID filters and PCR re-stamp.

If the RF-in is present and tuned well, the Lock LED will be on.
The factory default settings for RF-in is 474MHz/8MHz BW, and the RF-output
is 666MHz/8MHz BW.
To customize the settings, please refer to the following chapters.

4. Setup PC/NB environment for configuration
DTV Bridge configuration can be set or customized by a tool in PC Windows.
This chapter describes how to setup the tool in PC Windows.
4.1. Run Setup.exe to install configuration software on your PC/NB
In the start menu, a new submenu “DTV Bridge Controller” will be created.
4.2. Remove Jumper J1 for USB configuration mode
4.3. Connect USB port to your PC/NB
4.4. Driver install
In the first time usage, Windows will prompt to install driver. Depending on the
Windows OS type, please specify either 64 bit or 32 bit folder in <Driver>.
You may check if the driver is installed well in Device Manager.
“IT9517 Tx Device” should be listed if the install is successful.

Connect USB port to your PC.
In the start menu, launch “DTV Bridge Controller”.
If device is not found,
Please check,
a. if USB cable is connected well
b. Jumper J1 is removed properly.
c. IT9517 Driver is installed well in Device Manager.
If device is found,

Click on “Connect” to continue.
Click on “Configure” to continue.
Note: If there is any error message as shown below,
Please click on “Init EEPROM” to initialize EEPROM properly. Refer to the chapter
“Tool Usage-Initialize EEPROM”.

1. Read EEPROM
It retrieves current settings from board’s EEPROM.
2. Demodulator and Modulator Settings
For DVB-T to DVB-T, please set as,
Demod Chip: IT9133BX
Modulation Type: DVB-T
3. Receiver channel settings,
Specify the channel frequency and bandwidth for receiver.
The bandwidth supported depends on the jumper J2 of the receiver module.
The I2C address should be 0x3A for BR-101, and 0x38 for BR-100
Jumper J2 OFF: 2/3/4 MHz BW reception supported
Jumper J2 ON: 5/6/7/8 MHz BW reception supported
4. Receiver PID filter settings
PID filter can be enabled to filter out unwanted PID’s.
Two operation modes for PID filter, BLOCK mode and PASS mode.

In BLOCK mode, the PID’s specified will be blocked by the filter.
In PASS mode, the PID’s specified can pass the filter.
By default, it’s recommended to block null-packet (PID=0x1FFF).
5. Modulation Parameters
An IQ table can be specified to optimize the modulator performance, but it’s
optional and can be ignored.
6. PCR restamp and cell ID
DTV Bridge board supports PCR restamp feature to fix PCR jitter while
modulation.
It’s optional to enable it, and three restamp mechanisms are supported. Refer to
IT9510 datasheet for details.
Optionally, users may specifies the Tx cell ID desired.
7. Write EEPROM
Click on “Write EEPROM” for the new settings to take effect.
When configuration is done, set DTV bridge board in normal operation mode by short
Jumper J1. Then, power off and power on to reset.
