DVB-T/H Modulator Core
 
    Description

The MVD DVB-T/H modulator is a drop-in module that includes the following functions :
  • Input data framer from Microprocessor, MPEG_ASI or MPEG_SPI source (MPEG_TS flow)
  • DVB-T modulator
    • Energy dispersal
    • Reed Solomon encoder
    • Convolutional interleaver
    • FEC convolution encoder
    • Inner interleaver
    • QPSK/QAM symbol mapper
    • Framer with pilots & TPS inserter
    • IFFT and guard interval insertion
  • Flexible Digital Up Converter
  • Modulator for FI output
  • Output for simple DAC (14 bits) or complex DAC (2x16bits)

The MVD DVB-T/H modulator can be customized for specific application. In option, it can include :

  • Hierarchical transmission
  • In-depth interleaving for DVB-H
  • ASI interface core
  • Direct 32 bit CPU interface for configuration parameters and MPEG_TS input flow
