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 1) (Serial Data
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.
1) SDTI is defined as SMPTE 305M.
