DD RESI DVB-T / ISDB-T SDR modulator V2

The Resi DVB-T / ISDB-T modulator card is used to feed any DVB signal source into an existing 75 OHM coaxial cabling.

The Resi modulator card outputs a DVB-T or ISDB-T compatible data stream. For example, DVB-S/S2 channels fed in or even entire transponders are converted into DVB-T transponders according to your own ideas.

The RESI DVB-T / ISDB-T SDR Modulator V2 is used to feed any DVB signal source (hard disk, DVB-S, DVB-C, etc.) into an existing coaxial cabling system.

  • 14 transponders according to DVB-T / ISDB-T specification
  • Frequency range: 114 - 858 MHz
  • Modulation types: QPSK, QAM 16, QAM 64
  • Signal / noise ratio: 42dB
  • Output power at 14 channels (per channel): 97 dBµV

Other outputs can also be made on the DVB-T / ISDB-T transponders, such as a video stream of a file for the hotel's daily programme (Hotel TV) or the picture from a surveillance camera.

If you install a Common Interface in the system, you can even feed pre-decrypted programmes into the DVB-T / ISDB-T transponders.

With our Common Interfaces with MTD technology, you can decode up to 4 channels simultaneously, even on different transponders! (Please note the regulations of your PayTV provider or the regional public broadcasters).

Possible data sources:

  • DVB-S/S2 (Max S8 / SX8 / SX8 Basic)
  • DVB-C/C2 (Max A8, Max M4)
  • Video stream from a hard disk
  • Network
  • Surveillance camera

Due to its low profile, the RESI FSM fits into low and full profile housings.

The power consumption of the RESI DVB-T / ISDB-T SDR Modulator V2 is 20 watts.

For operation, application software is required, which is not included in the scope of delivery. For application developers, sample programs under Linux available.
