The DVB-S2 LDPC-BCH block is a FEC (Forward Error Correction) subsystem for Digital Video Broadcasting via Satellite.

Contact Provider Request Datasheet

Overview

The DVB-S2 LDPC-BCH block is a powerful FEC (Forward Error Correction) subsystem for Digital Video Broadcasting via Satellite. In Digital video broadcasting for digital transmission for satellite applications, a powerful FEC sub-system is needed. FEC is based on LDPC (Low Density Parity Check) codes concatenated with BCH (Bose Chaudhuri Hocquenghem) codes, allowing Quasi Error Free operation close to the Shannon limit.

Key features

  • Irregular parity check matrix
  • Layered Decoding
  • Minimum sum algorithm
  • Soft decision decoding
  • BCH decoder works on GF (2m) where m=16 or 14 and corrects up to t errors, where t = 8, 10 or 12
  • ETSI EN 302 307-1 V1.4.1 (2014-11) compliant
  • Long and short frame lengths
  • No error floor to QEF in Standard
  • Easy to integrate within receiver
  • All code rates and modulation orders
  • Wideband support

Benefits

  • Improved performance
  • Improved efficiency w.r.t. Shannon’s limit
  • Very high data rate

Applications

  • DVB-S2

Practical Considerations of LDPC Decoder Design in Communications Systems

This paper covers some practical aspects of designing the LDPC decoder starting from comparison between different techniques, different decoders parameters or standards, the effect of those parameters on the LDPC performance, also it discusses the algorithm selection process, and floating point implementation process.

Audio Transport in DisplayPort VIP

DisplayPort uses Secondary Data Packets (SDPs), which are transported over the Main-Link that are not main video stream data. This allows it to carry audio and video simultaneously. The VIP supports audio transmission both in the original mode as defined in the specification as well as just as any other SDP being transmitted.
