DVB-C2 (Digital Video Broadcast – Cable 2nd Generation) is an ETSI standard of the second generation for digital data transmission via cable networks. It complements the existing standards DVB-S2 and DVB-T2 for satellite and terrestrial communication and offers a capacity-approaching coding scheme. The Creonic DVB-C2 IP core integrates the forward error correction as defined by the standard (including LDPC and BCH decoder).









  • Digital Video Broadcasting

  • Further applications with the highest demands on forward error correction

Standard Features the Core Supports

  • Compliant with ETSI 302 769 V1.2.1 (2011-04) (DVB-C2)
  • Support for short blocks (16200 bits) and long blocks (64800 bits).
  • Support for all modulation schemes (16-QAM, 64-QAM, 256-QAM, 1024-QAM, 4096-QAM)
  • Support for all interleaving schemes of all modulation schemes.
  • Support for all LDPC and BCH codes as defined by the standard
  • Support for decoding of L1 signalling part 2 data


  Your Benefits


  • Soft-Decision demapper, block deinterleaver, LDPC decoder, BCH decoder, and descrambler included.
  • Based on industry-proven design for DVB-S2
  • Low-power and low-complexity design
  • Burst-to-burst on-the-fly configuration
  • Design-time configuration of throughput for optimal resource utilization
  • Faster convergence due to layered LDPC decoder architecture
  • Early stopping criterion for iterative LDPC decoder, saving a considerable amount of energy

  • Configurable amount of LDPC decoding iterations for trading-off throughput and error correction performance
  • Collection of statistic information (number of modified information bits, number of iterations, decoding successful)
  • Available for ASIC and FPGAs (Xilinx, Intel)
  • Deliverable includes VHDL source code or synthesized netlist, VHDL testbench, and bit-accurate Matlab, C or C++ simulation model
  • The software model includes the corresponding transmitter part
