Televés reserves the right to modify the product.The product may be different than shown in the picture.

This transmodulator generates a COFDM multiplex by multiplexing services from up to 3 satellite digital transponders. These services can be extracted either from 2 different satellites (2 independent SAT IF inputs) or from 1 satellite and the input loop-through of the headend itself.

  • Adaptation of the transport stream to the requirements of the DVB-T by:
    • Inclusion of null packets (“Stuffing”) for faster scans of the receiver (STB).*
    • Total or selective deleting of services from the received Multiplexes to avoid being detected (and stored) by the receiver (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.
  • PID filtering, allows you to delete services not interested in a multiplex (exploiting the occupation). Very interesting feature when used with a CAM.
  • 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).*
  • Provides information about the occupation of each service and the total occupation of the COFDM output signal, which allows optimization of distributed services.
  • Edition of S_ID, to avoid retuning of receivers (STB)* when the services of a multiplex are changed at its output.
  • Through its CI interface, and the corresponding CAM module, encrypted satellite channels become free DTT services. According to the CAM used (standard/ professional) it is possible open one or more services for free TV.
