DVB-T2/Lite LDPC Decoder IP

In Digital video broadcasting for terrestrial broadcasting systems, a FEC sub-system is needed.

Overview

In Digital video broadcasting for terrestrial broadcasting systems, 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.
T2-Lite is intended to allow simpler receiver implementations for very low capacity applications such as mobile broadcasting, although it may also be received by conventional stationary receivers.

Key features

  • Irregular parity check matrix
  • Layered Decoding
  • Minimum sum algorithm
  • Configurable number of iteration
  • Soft decision decoding
  • ETSI EN 302 755 V1.4.1 (2015-07) compliant
  • T2-Lite has two more code rates; 1/3 and 2/5 for the short frame length

What’s Included?

  • Synthesizable Verilog
  • System Model (Matlab) and documentation
  • Verilog Test Benches
  • Documentation

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.
