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. TS IN1 TS IN2 TS OUT1 Phase Adjust TS OUT2 Phase Adjust TS OUT3 TS IN3 Phase Adjust Clock System Select TS OUT4 Transmit Clock Gen STC/GOP/ISDBT Sync Signal GOP Sync Gen Control Alarm Control 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.
