DVB-T signal distribution with precise time synchronization in SFN network
The DVB-T link example describes the combination of DVB-T traffic transport with precise time (1PPS) and frequency (10MHz) remote synchronization which was especially designed for SFN broadcasting networks. This example is established from WAVEFORM HS system. Optionally 1+1 protection mode can be configured for such DVB-T application.
Description and Advantages
The DVB-T link is established from WAVEFORM HS IDU and connected EMM-ASITSI module. The TSI extension ensures precise time (1PPS) and precise frequency (10MHz) synchronization over link from remote side thus eliminates either GSM signal or expensive external packet based synchronization units necessity for such synchronization. It is important especially for SFN broadcasting networks.
- optional precise time (1PPS) and precise frequency (10MHz) synchronization
- built in holdover feature with long time stability during link down event
- optional 1+1 protection
- universal EMM-ASITSI for Tx and Rx direction
- optional simplex link configuration
