DVB-H/DVB-T Live Data Processing

SAMcorder is acting as central input/output processor, managing all input/output operations.

SAMcorder is interacting in real-time with almost all dvbSAM components (SAMager Agent, SAMalyzer, SAMbera, SAMbuddy, SAMcover, SAMesg, SAMflute and SAMitor). It interacts with all these components simultaneously, de-multiplexes the transport stream in real-time and provides all these components the data needed for their operation, regardless of which input interface gets used.

It also acts as central data exchange, i.e. it receives analysis results from these components (e.g. ESG data from SAMesg) and provides it to other components for further processing.

SAMcorder's output capabilities are outstanding. It manages dozens of outputs simultaneously, thereby supporting individual configuration of every particular output.

Furthermore SAMcorder performs various RF measurements.

For DVB-H SAMcorder includes its own ISMAcryp engine which enables SAMcorder to descramble ISMAcryp encryped DVB-H video and audio programs based on OMA BCAST DRM and SCP profiles. All programs inside a channel can be descrambled simultaneously and afterwards displayed in a mosaic wall.

SAMcorder attaches a wide range of RF, ASI and Modulator input/output hardware to dvbSAM. Furthermore it manages unlimited input/output via IP, UDP, TCP and Pipes, performs descrambling and comprehensive measurements in DVB transmissions.

Key Attributes:
  • live input of DVB-H/-T/-S/-S2 multiplexes using a wide range of DirectShow BDA compliant RF tuners, various Teamcast and DekTec RF receivers, various ASI/SPI capture devices, IP interfaces and recorded multiplexes
  • live output to various IP streamers, ASI/SPI output devices, OFDM modulator devices and files (recording)
  • supporting various types of IP based output streamers:
    • complete multiplex
    • particular DVB-T/-S/-S2 programs out of the multiplex
    • particular DVB-H services (video/audio/FLUTE/ESG/key streams/...) out of the multiplex
  • number of simultan IP streams is unlimited
  • same data can be streamed to different destinations simultan.
  • support of IP multicast (input and output)
  • comprehensive RF channel scan feature
  • supports various RF receivers for performing RF measurements
  • takes transport stream snapshots on mouse click
  • very detailed and versatile configuration possibilities
  • easy navigation within the programs and services of the multiplex
  • provides comfortable graphical user interface
  • capable of unattended operation at 24/7
