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.
