Program Navigation

In a first analysis of the received Transport Stream all announced program services and their corresponding PIDs are listed in a tree view. Additional information are provided, e.g. information about the Video and Audio encoding.

Via simple double click on a program entry an appropriate IP streamer for this program can be created, see also the section ‘Streaming’ below.

RF Measurement

On the RF layer SAMcorder provides simple signal checks which are provided by the BDA driver of the used RF receiver:

  • Signal Present
  • Signal Locked
  • Signal Strength
  • Signal Quality

Note: For DVB broadcasts. i.e. for DVB-T/-T2, DVB-S/-S2 and DVB-C, there is a dedicated dtvTools application named SAMbuddy-RF which provides detailed RF measurements (RX level, BER, MER and many more), including the display of constellation diagram, read more…

MPEG Layer - TR 101 290 Monitoring

The  in-depth MPEG monitoring according ETSI TR 101 290 specification is divided in three parts:

  • Prio1
  • Prio2
  • Prio3

Individual thresholds for upper and lower limit can be defined for each single parameter.

PID Bitrate Measurement

Each particular PID of the multiplex gets listed in a tree view and additional information to an appropriate PID are displayed.

The Current Bitrate and the Average Bitrate for each particular PID are measured.

Individual thresholds for upper and lower limit can be defined.

PID Bitrate Measurement

Program Bitrate Measurement

For each program the bitrate can be measured and monitored, i.e. the overall bitrate of all PIDs which belong to the appropriate program service.

Individual thresholds for upper and lower limit can be defined.

SAMcorder de-multiplexes the current received Transport Stream and  supports streaming via IP/UDP. Various types of IP streamers are possible:
  • complete multiplex (TS)
  • particular DTV programs out of the multiplex
  • particular PID or PIDs out of the multiplex
  • particular Audio service out of the multiplex

The number of simultaneous IP streamers is not limited. Data duplication is possible, i.e. same data can be streamed to different destinations simultaneously. Beside IP streaming to remote locations, the data can also be streamed into a local file, whereby the file streaming can be configured regarding time and size thresholds.
