Features

The DSM-T1 Digital Satellite Modulator modulates
analog video and audio input signals into digital
signals. This modulator enables an SNG (Satellite
News Gathering) system in combination with the
DSM-R1 Digital Satellite Demodulator.
The following are some of the features of the DSM-T1.

Easy Installation

The DSM-T1 provides easy connection with an
existing SNG system via IF OUT (Intermediate
Frequency output).

High quality compression algorithm

MPEG2 4:2:2 profile at Main Level (4:2:2 P@ML)
ensures superior picture quality at 18 MHz
transmission bandwidth.

Direct digital transmission at up to twice
real time

The DSM-T1 enables transmission at up to twice real
time speed at 36 MHz transmission bandwidth with
connection of a DNW-A100/A100P digital video
cassette recorder through the SDTI
Transport Interface). This feature contributes to
increase of news gathering productivity.

Optional interface boards available

The BKSM-T101 SDTI Input Board, the BKSM-T102
SDI Input Board, and the BKSM-T103 Analog Input
Board provide flexible choices of installing one or two
boards to this unit.

Two-program Transmission

Two multiplexed video and audio signals can be
transmitted simultaneously at 36 MHz transmission
bandwidth. This contributes to lower transmission
costs.

Locations and Functions of Parts and Controls

4 INPUT SEL (input selection) indicators

IN1: Lights up when input signals from the optional

board in the IN1 section are transmitted from the
IF OUT connector.

IN2: Lights up when input signals from the optional

board in the IN2 section are transmitted from the

IF OUT connector.
When input signals from both optional boards are
simultaneously transmitted, both indicators light up.
To select from which optional board section input
signals are transmitted, select “01: INPUT SELECT”
in the menu.
When no signals are supplied to the selected board
slots, the indicator flashes. If the destination address
of the input signals and the address selected in the
menu are different when the BKSM-T101 SDTI Input
Board is installed, the indicator also flashes.
To select the address of this unit, select “43: My
ADDR-1”“53:MY ADDR-2” in the menu.

For more information, see “Menu Setup” (page 10).

5 AUDIO SEL indicators
IN1 indicators

CH1/2: Lights up if input signals from the optional

board in the IN1 section are transmitted when;

-The FEC RATE is 7/8

or

-The FEC RATE is 3/4 and IN1 AUDIO CH is
CH1/CH2.

CH3/4: Lights up if input signals from the optional

board in the IN1 section are transmitted when;

-The FEC RATE is 7/8

or

-The FEC RATE is 3/4 and IN1 AUDIO CH is
CH3/CH4.

When the BKSM-T103 Analog Input Board is
installed and 3-pin XLR connectors are used, the
indicator does not light regardless of the FEC

RATE selection.
To select the FEC rate, select “12: FEC RATE” in the
menu.
To select the audio channels for the optional board in
the IN1 section, select “47: IN1 AUDIO CH” in the

board in the IN2 section are transmitted when;

-The FEC RATE is 7/8
or

-The FEC RATE is 3/4 and IN2 AUDIO CH is
CH1/CH2.

CH3/4: Lights up if input signals from the optional

board in the IN2 section are transmitted when;

-The FEC RATE is 7/8

or

-The FEC RATE is 3/4 and IN2 AUDIO CH is
CH3/CH4.

When the BKSM-T103 Analog Input Board is
installed and 3-pin XLR connectors are used, the
indicator does not light up regardless of the

selection of the FEC RATE.
To select the FEC rate, select “12: FEC RATE” in the
menu.
To select the audio channels for the optional board in
