Transmodulator DVBS / S2 – COFDM
KSh187,174.00
Transmodulator that generates a DTT multiplex from services whose origin is a TVSAT transponder in either DVBS (QPSK) or DVBS2 (QPSK /8PSK) modulation formats.
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
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.
