DVBS/S2 Transmodulator with CI - COFDM Televes

Equipped with CI. The transmodulator receives a SAT transponder in DVBS (QPSK) or DVBS2 (QPSK /8PSK) modulation and demodulates it, producing an MPEG-2 transport packet. The MPEG2 transport packet is subsequently modulated in COFDM and converted into the output channel (UHF or VHF, with a 7/8 MHz bandwidth), using an agile up-converter. Televes 563301

DVBS/S2 Transmodulator with CI - COFDM Televes

€673.87 €1,036.73 Save 35%

Equipped with CI. Transmodulator that generates a DTT multiplex from services whose origin is a TVSAT transponder in either DVBS (QPSK) or DVBS2 (QPSK /8PSK) modulation formats.
Once extracted the MPEG2 TS, it is re-modulated in COFDM format to obtain an output channel (7/8 MHz bandwidth) in VHF/UHF by means of a agile up-converter.
Settings of operation parameters can be performed by means of the programming unit (ref. 7234): input frequency, output channel, modulation format and adaptation of services, mainly.

Features

  • Equipped with CI.
  • Total or selective elimination of services received, so that they cannot be detected (and stored) by the STB*.
  • Edition of TS_ID to facilitate detection of programs / services in the receiver (STB).*
  • Edition of Network_ID, Original Network_ID and Cell_ ID to control network IDs.
  • Allows you to assign an LCN (Logical Channel Number) to the services present in the output, which facilitates the management of channels in the receiver (STB).*
  • Edition of S_ID, to avoid retuning of receivers (STB)* when the services of a multiplex are changed at its output.
