DAB/DVB

Synchronization clocks for Digital Video and Audio Broadcasting

Transmission of DVB performed via SFN requires systems enhanced with Synchronization! For each time slot, every transmitter must broadcast the same digital data at the same frequency! Quality and Reliability is ensured when every signal is aligned in frequency and time « Mega Frame » data packets and Orthogonal Frequency Division Multiplexing (OFDM) must be synchronized for similar waveforms at each transmitter Avoids cross-talks in the coded OFDM frequencies Control Phase noise and spurious for Phase-shift keying (QPSK) or Quadrature Amplitude Modulation (QAM).The Synchronization plays an important role in DVB (DVB-T, DVB-H): 

  • For Operation Reliability of new Digital Broadcast Deployments 
  • It improves efficiency of MFN (Multi-Frequency Network) 
  • It is mandatory fro SFN (Single-Frequency Network)

Oscilloquartz Solutions are compliant with : DAB, DVB-T, DVB-H, DVB-SH, FLO, T-DMB, DRM, etc.
