Overview

The DVB-S2/S LDPC/BCH decoder a silicon proven IP extracted from production chips has an octal input interface and a single output interface. The data coming from the 8 demodulators are multiplexed and decoded by the same engine. After decoding, 8 packet delineators do the demultiplexing and DVB-S2 de-framing before sending data to the output transport stream manager.

For a 258-MHz clock we may have a maximum data rate of 258 Mchannel-bit/s (megaLLRs)at the input to the FEC decoder. Advanced power-saving features have been implemented, the LDPC stops once the solution is sufficiently converged and the various blocks of the IC (tuner, demodulator, LDPC, Legacy FEC, and so on) may be completely shut down if not required. The device also supports Wake-on-network PID.

Key features

  • Multiplexed LDPC/BCH decoder: The DVB-S2 FEC block can simultaneously decode 8 independent input streams. Each input stream has its own input connection. However, the cell only includes one LDPC decoder and one BCH decoder. Thus, the 8 input streams are stored in 8 independent buffers. When a frame is ready, it is processed in the LDPC decoder, then in the BCHdecoder and finally output to the appropriate transport stream.
  • LDPC decoder: The LDPC decoder can decode normal and short frames and all DVB-S2 and S2X Broadcast and Interactive profiles, but not VLSNR.
  • BCH Decoder: The BCH decoder is able to correct up to 12bits for Code rates where more than 192 redundancy bits are available. As such, correction is only possible up to 10bits for 2/3 and 5/6 code rates, and only up to 8bits for 8/9 and 9/10 code rates.
  • Packet Delinter: The packet delineator is used for descrambling, checking the integrity of BBFrame headers, processing the cache and data fields and providing a lock indicator

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.
