Processing

The module performs the following operations:

  1. Receiving MPEG-TS stream with DVB-T2 signal
  2. Decoding T2MI (T2-MI) containers
  3. Extracting PLP (Physical Layer Pipe) data
  4. Forming standard MPEG-TS stream for further processing

Supported Formats

The module works with the following data types:

  • DVB-T2 signals
  • MPEG-TS containers
