TS-S1631
ISDB-T Frame Sync Signal Switcher
For Terrestrial Digital Broadcasting
マスタ タイトルの書式設定
This unit adjusts the frame phases between individual input signals for the multiple
broadcasting TS signals having a different phase relative to each other, which are compliant
with the ISDB-T transmission scheme and performs system switching with the ISDB-T frame
structure maintained to output the processed TS signal.

Features
Supports maximum three inputs of TS signals
Supports dual-redundant PS
The unit accepts up to three inputs of broadcasting TS
signals and performs system switching with the ISDB-T
frame structure maintained to output the processed TS signal.
The unit supports a dual–redundant configuration for the
power supplies.
Automatic adjustment of frame phase
The unit detects an ISDB-T frame sync signal from each input
broadcasting TS signal, and automatically adjusts the frame
phase difference of each input signal.
Supports seamless switching
By integrating this unit into a complete system with NEC
ISDB-T sync signal generator and NEC MUX unit, you can
switch between the broadcasting TS signals outputted from
the main and standby MUX units with the ISDB-T frame
structure maintained.
