» Streaming «

(1) The entire T2-MI Transport Stream can be streamed to a remote destination 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 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 dtvTools 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 …

» PLP Real-Time Analysis and A/V Monitoring «

The content of an extracted PLP can be streamed to the SAMcorder application via IP or IPC. SAMcorder provides a comprehensive real-time service analysis and monitoring on all technical layers:

  • MPEG analysis acc. TR 101 290
  • PID and Program Bit-Rates measurements
  • EPG analysis and monitoring
  • DVB Subtitle analysis and monitoring
  • DVB Teletext analysis and monitoring
  • DSMCC / MHP / HbbTV analysis and monitoring
  • Conditional Access analysis

SAMcorder de-multiplexes the Audio/Video content from the PLP and can stream the A/V data to the Audio/Video wall SAMitor for visual monitoring. That way all TV programs carried within all PLPs within a T2-MI stream can be visualized lively in this video wall.
Additionally SAMcorder can also stream all Audio data to SAMloudio for a professional Loudness and Audio analysis. That way also all Audio services carried within all PLPs within a T2-MI stream can be analyzed/monitored lively right from the T2-MI stream.
