T2-MI Input

  – UDP unicast/multicast
  – RTP
  – support of various suppliers
– play-back of recorded T2-MI streams

SAMbuddy-T2MI supports both streams with SI tables (PAT/PMT + PCR info) and without SI tables. For streams without SI tables the needed T2-MI PID can be defined manually.

[1] The entire T2-MI Transport Stream can be streamed to local or remote destinations for further analysis tasks, e.g. MPEG analysis according ETSI TR 101 290.

[2] SAMbuddy-T2MI extracts all PLPs from the current T2-MI Transport Stream and each particular PLP can be streamed to a local or remote destination for further analysis tasks on all technical layers, e.g. MPEG, EPG, Subtitle, Audio/Video …

Cross-Check T2-MI and Modulator RF Output

Service and network providers have to check whether the parameters of the RF output signal of the transmitter corresponds to the parameters of the T2-MI input signal.
With decontis solutions such a check can be realized very easily. The figure on the right shows a typical application. In the head-end a decontis monitoring probe receives the T2-MI signal via IP or ASI interface and in the field one or more decontis monitoring probes receive the DVB-T2 signal via RF receivers. On the field monitoring probes the SAMbuddy-RF application is running and in the head-end probe the application SAMbuddy-T2MI is running. To get the RF parameters from a field monitoring probe, SAMbuddy-T2MI creates IP connections to the corresponding SAMbuddy-RF application(s). Beside the T2-MI parameters, SAMbuddy-T2MI receives and displays the current RF measurements from SAMbuddy-RF, e.g. Rx Level, BERaV, MER, PER …
