DTV - PSIP Pro - Electronic Program Guide

DTVi's TSACO-1000 is a fail safe protection switch that automatically prevents TV broadcasters from unexpectedly going off air. The TSACO-1000 enables a broadcast station to automatically switch from a primary transport stream to a backup transport stream in the event the primary fails. The Changeover Switch will accept inputs in either ASI or SMPTE 310.

SIGNAL HEALTH MONITORING
The primary and backup inputs are monitored to determine whether both inputs have valid packet headers sync bytes(47 hex). If the sync byte is not detected on the primary input, the protection switch will automatically switch to the backup transport stream input. Once the fault has been cleared, the broadcaster will be able to manually switch back to the primary input.
