Transportable and Portable Means for Radio Monitoring

ARC-TVRV

Transportable Unattended System of Automated Monitoring of TV and Radio Broadcast

Purpose:

  • Automated monitoring of TV and radio broadcast operated standalone or as a part of fixed means (ARCHA-IN) or automated spectrum monitoring systems (ARMADA, AREAL etc.)

System Provides:

  • Revealing of information component of TV and radio broadcast signals
  • Recording of demodulated TV and radio signals, and geographic coordinates, data and time of the record, 24/7
  • Recording of subtitles of digital channels
  • Simultaneous monitoring up to 16 analogue and up to 20 digital TV and radio channels and recording of content and parameters based on pre-set trigger events
  • Sequential monitoring of arbitrary number of analogue and digital TV and radio channels and recording of frames and parameters based on pre-set trigger events
  • Simultaneous recording of up to 8 arbitrary chosen analogue, digital TV and radio channels
  • Visual and audio monitoring of TV and radio broadcast signals
  • Monitoring of fade and scattering if DTV picture
  • Generation of reports as per operation results.
  • Support of control via (Ethernet) and back-up (3G/4G) communication channel with automatic switch between them
  • Adjustable notifications of the operator about external power interruption, activation of intrusion sensors, communication channel switch
  • Remote diagnostics and system reboot in case of contingency event


When operated as a part of ARCHA-IN, ARCHA-INM stations, ARC-TVRV provides additionally for measuring of technical parameters of TV and radio broadcasts signals (levels, frequency, bandwidth, modulation parameters) At this, for DVB-T2 signals the following functions are provided:

  • Automatic determination of distribution scheme of dispersed pilot signals (PP1; PP2; PP3; PP4; PP5; PP6; PP7)
  • Determination of modulation type (QPSK; 16-QAM; 64-QAM; 256-QAM) of PLP single stream in single stream mode A or PLP selected stream in multistream mode B
  • Determination of relative rate of code with low density of parity checks (LDPC) for PLP single stream in single stream mode A or selected PLP stream in multistream mode B. Relative code rate should correspond to series of allowable values: 1/4; 1/2; 3/5; 2/3; 3/4; 4/5; 5/6.
  • Determination of frame length (16K; 64K) with noiseless coding (FECFRAME)
  • Imaging signal constellation for:
    • Single PLP stream in single stream mode A;
    • Selected PLP stream in multistream mode B;
    • Р1 preamble symbols;
    • L1 signaling
  • Determination of spatial separation mode for transmitting antennae set (SISO; MISO)
  • Determination of per bit error rate before Bose-Chaudhuri-Hocquenghem code (hereinafter, BCH code) decoder
  • Determination of relative amount of erroneous streaming frames (BBFRAME)
  • Determination of relative amount of erroneous packages of transport stream
  • Determination of modulation error ratio for single PLP stream in single stream mode A or selected PLP stream in multistream mode B
  • Measurement of amount of received PLP streams in multistream mode B
  • Analysis of transport stream structure and relevant service information tables (SI/PSI)
  • Measurement of full transport stream rate, actual rate of each transport stream program and each package type having data package identifier (PID), separately
