Application scenarios

  • Scenario I: Copyright Protection Monitoring
  • Scenario II: Advertisement and Music Monitoring
  • Scenario III: Radioplayer
  • Scenario IV: Technical Monitoring
  • Scenario V: Hybrid Broadcasting
  • Scenario VI: New Advertising Forms

Why Radio Monitoring is necessary?

  • Web-streaming and broadcast contents could be different
  • Local and regional stations or regional content inserts are not online
  • Regional restrictions for the content access
  • Significant audio delays on the web-streams ->not acceptable for hybrid radio
  • Different standards and protocols for content access
  • Law-requirements: monitoring should be on the broadcast audio and not on the internet streams
  • Controlling of the regional partners and broadcast signals
  • Radioplayer or aggregator-sites scenario: radio monitoring system cannot be easily blocked or manipulated
  • Innovative radio advertisement monitoring
  • Access to the broadcasting meta-data, e.g. RDS

Our Solution

Scalable multi-channel hardware and software platform for remote broadcasting monitoring of FM broadcast radio stations (87.5…108 MHz band) and DAB+ radio stations (174…240 MHz band). The platfrom can also be configured to support AM, DRM, DRM+, HD, SDR or Microphone Arrays.

Technical characteristics

  • Operating frequency range in FM format, 76…108 MHz
  • Operating frequency range in DAB+ format, 168…240 MHz
  • Built-in multi-channel splitter for use with only one antenna
  • Minimum number of simultaneously received channels in FM/DAB+: 8 channels
  • Maximum number of simultaneously received channels in FM/DAB+: 62 channels (93 or more channels configuration on request)
  • AM, DRM, DRM+, HD support on request
  • SDR, Line-In, microphones or microphone arrays scenarios are possible; unlimited number of channels (on request)
  • All channels sample synchronously; multi-units synchronization is possible
  • Custom configuration, scaling step, 8 channels
  • Depth of audio content encoding 16 bit (24 bits on request)
  • Stereo/mono operation modes
  • Audio Encoding frequency, 48 kHz
  • Program Associated Data (PAD) decoding RDS, RBDS, MOT
  • Compression formats (software installed) mp3, AAC
  • Transmission speed of one broadcast channel over the Internet (set programmatically)
  • Ethernet 100/1000Mbit/s
  • Ethernet port IEEE 802.3, 802.3u, 100/1000Base-TX
