DVB-T2

DVB-T2 is the world’s most advanced digital terrestrial transmission system offering higher efficiency, robustness and flexibility. It introduces the latest modulation and coding techniques to enable highly efficient use of valuable terrestrial spectrum for the delivery of audio, video and data services to fixed, portable and mobile devices.

  • KEY FACTS
    • OFDM (Orthogonal Frequency Division Multiplex) modulation
    • Large range of modes: 5Mb/s to 50Mb/s
    • Efficient channel coding based on LDPC (Low Density Parity Check code) combined with BCH (Bose-Chaudhuri-Hocquengham)
    • Service Specific coding based on Multi-PLP (Physical Layer Pipes)
    • Configurable Time interleaving depth enabling optimization of signal coverage
    • MISO (Multiple Input Single Output) method known as Alamouti coding
    • Rotated constellation method
    • Advanced clipping functions Peak to Average Power Reduction (PAPR) techniques
    • Improved signal quality and amplifier efficiency
  •  KEY ADVANTAGES OF DVB-T2 MIGRATION
    • Up to 50% and more capacity gain are achieved
    • Up to 6 HDTV multiplexed programs
    • Service specific robustness enabling new revenues for program regionalization, program diversification and in band mobile applications
    • Enhanced SFN performances for spectrum saving
    • DVB-T2 standard is built for IP or Transport stream distribution network
  • KEY BENEFITS
    • Offering of 3D or HD services
    • New efficient business models based on additional revenues from new services
    • Switching directly to DVB-T2 is a real opportunity to save spectrum transmitting the same services
