Input docsis

Input docsis will read DOCSIS packets from a DVB-C or a ATSC/QAM card.
It it optimised for DOCSIS packets in several ways :

  • It will read only MPEG packets with the DOCSIS PID from the DVB card using hardware filtering
  • DOCSIS packets will be reassembled on the input level, making it faster for the core to process them
  • Both DVB-C and ATSC/QAM cards are supported and the correct DOCSIS version will be used accordingly
  • Less configuration parameters are required since DOCSIS have mandatory symbol rate
