MPEG2-TS PROCESSING


  • The extracted MPEG2-TS from the COFDM Front-End or from the ASI input is analyzed according to the standard TR 101 290.
  • The services selected in the TS by the user, video PID and audio PID, are decoded.
  • The video  composite signal is supplied  on a BNC connector at the rear of the equipment.
  • Simultaneously the RGB color components are provided on a D-SUB /HD 15 pins (VGA type) connector.
  • The selected audio channels are supplied  on XLR 5 type connector.

MPEG2-TS ANALYSIS-MEASUREMENT


The equipment provides permanently:
  • RF quality measurements: BER (channel BER) before and after Viterbi correction, MER, number of uncorrected packets, RF absolute and relative level, frequency and clock rate offsets, SFN delay (References Inputs for SFN modes: 10 MHz and 1 pps.)
  • Transport stream description: list of services and components (PID) with measured bit rate (minimum, maximum and average values).
  • Analysis according to TR 101 290
  • 1.1 TS synchro Loss /1.2 Synchro Error/1.3 PAT Error/1.4 Continuity Indicator
  • Error/1.5 PMT Error1.6 PID Error/2.1 Error Indicator to 1/2.2 CRC Error …/2.3 PCR recurrence/
  • 2.4 Selected program(s) PCR precision] 2.5 PTS recurrence/2.6 CAT Error/
  • 3.1 NIT Error/3.2 SI SI recurrence/3.4 PID not referred/3.5 SDT Error. 3.6 EIT
  • Error/3.7 RST Error/3.8 TDT Error

ALARMS


  • The equipment provides an alarm for each measurement.
  • The alarm threshold can be set individually.
  • Alarms can be sent through ethernet interface using the MIB parameters
  • 4 synthesis alarms are provided: they allow the combination of 1 or more alarms according to a scheme defined by the user.
  • Access to theses 4 alarms is provided on relay contacts at the rear.
  • On the front panel, 3 pre-defined synthesis alarms (RF, COFDM et MPEG) and 4 user defined synthesis alarms are displayed on 6 LEDS.
  • Alarm status can be accessed through the serial link or remotely

REMOTE CONTROL


  • Through relays: 4 user’s defined synthesis alarms and “power supply on” are available.
  • Remote Reset is allowed by strapping 2 contacts on the “dry contacts”connector.
  • Through RS232 serial link: a console monitor allows access to all functions of the equipment: configuration, measures, alarms.
  • Through an Ethernet PCP/IP proxy board, full remote control is available using HTTP, FTP, SNMP protocols. Web server is embedded.
