  • Understand how to work without time code and video/audio reference signals
  • Understand PTP (Precision Time Protocol) and RTP synchronisation

Target Audience

Technical staff working with high bitrate broadcast technologies who need to become familiar with the specific methods, concepts and terminology used in this field.
