• real-time monitoring of the complete DTV + MDTV multiplex on MPEG-2 layer acc. ETSI TR 101290
• monitoring ATSC DTV PIDs and Program bitrates incl. error indication according configured thresholds
• real-time monitoring of all MDTV specific IP/Port bitrates incl. error indication according configured thresholds
• real-time monitoring of the RTP sequence counter continuity
• real-time monitoring of M-EAS services
• EPG monitoring – all tables, current/next event, program preview
• monitoring ATSC, QAM and ATSC-M/H Closed Captions (CC) for CEA 608, 708 and SCTE-20 CC’s
• individual configuration of error and warning thresholds for each particular real-time analyzed parameter
• de-multiplexing of all programs within the channel/multiplex for both all DTV and MDTV programs simultaneously
• streaming of the de-multiplexed programs via IP to other destinations for both all ATSC and MDTV programs simultaneously
• de-scrambling of ATSC-M/H services

atscSAM ESG Monitoring

• supports OMA BCAST standard
  

  atscSAM ESG Monitoring

• supports UDP unicast and multicast
• automatic creation of all IP listeners according to the ESG content
• supports single and multiple transport mechanism
• stores all ESG content (XML’s, SDP’s, images, …)  into separate directories
• handles ESG updates automatically
• includes versatile features for performing a permanent real-time monitoring of all ESG’s within a multiplex
• performs comprehensive consistency checks
• ESG cycle timing monitoring
• ESG update timing monitoring

atscSAM A/V Monitoring Wall

• simultaneous playback of DTV and MDTV video and audio services,
  also arbitrarily mixed

A/V Monitoring

• support of all video and audio formats used in these broadcast technologies (MPEG-2, MPEG-4, H.264…)
• comprehensive realtime transcoding and streaming features for seamless streaming of regional ATSC and ATSC M/H programs over network at a low bandwidth into a remote operation center for visual monitoring
• support for regular TV image snapshot creation and streaming (provides visual monitoring at ultra-low bandwidth)
• provides audio bars for visual monitoring of audio channels
• adjustable number of monitor columns and tiles
• adjustable monitor sizes to optimal fit to the available screen size
• support of IP multicast
• monitoring A/V freeze, A/V signal loss, audio silence
• recording of single A/V services

atscSAM Loudness Measurement and Monitoring

• Integrated Loudness according ITU-R BS.1770.3, EBU R-128 and ATSC A/85 for monitoring e.g. CALM act compliance

SAMloudio Analysis Tile

• Momentary Loudness (400 ms integration time, 75% overlapping, 10 measurements per second)
• Short Term Loudness (3 seconds integration time)
• True Peak Level (TPL) measurement of every sub-channel
  (incl. 4-times oversampling for enhanced accuracy, 10 measurements per second)
• Loudness Range
• Live Meter (60 seconds, scalable, more than 100 live meters can be displayed on a single 4k screen)
• Solution is CPU efficient, it can analyze/monitor the loudness of more than 100 audio streams on a recent Core i7 CPU incl. all measurements and visualizations
• can be used along with arbitrary MPEG, AAC and AC3 audio codecs
• supports Digital TV and Mobile DTV
• can be used stand-alone or integrated with atscSAM and dvbSAM

Monitoring Summary Window

• all parameters like target loudness, warning and error thresholds, loudness scales etc. are configurable individually for every audio stream
• fully integrated into decontis SNMP tool chain for automated 24/7 SNMP based monitoring
• for any audio stream a live playback is possible, even for several streams simultaneously, if required for any reason

atscSAM NRT Analyzer

• in-depth analysis of data carousels transmitted via FLUTE/ALC protocol
  within DTV/MDTV multiplexes
• processes several FLUTE carousels simultaneously
  

  NRT/M-EAS Monitoring

• extracts and stores all FDT instances
• extracts and stores all transmitted files
• display of announced and actually received files, file sizes, TOIs, encodings…
• measurement of carousel cycle times
• calculation of the file transfer bitrate for each carousel
• decoding of XML, ESG and announcement files
• endless archive of all received files ever transmitted within a data carousel
• supports UDP unicast and multicast
• can act as independent FLUTE client, thus can be used standalone

atscSAM MDTV Real-Time Descrambling

Key Management

• automatic access to 3^rd party monitoring extensions
• this instance attaches a 3^rd party Conditional Access System for analyzing, SNMP based monitoring and also for playback of IPsec protected ATSC-M/H video services
• that way the atscSAM monitoring solution works also on scrambled content, e.g. thereby:
  • detects Video Freeze, Audio Freeze, Audio Silence and Audio/Video Signal Loss for all video/audio services
  • enables SNMP based monitoring of hundreds of parameters for ATSC-M/H multiplexes
    

    Real-Time Descrambling

• provides comfortable graphical user interface
• capable of unattended operation at 24/7
