High performance and cost effective DVB-S/DSNG/S2/S2X modulator for product integration.

VYP is a state-of-the-art satellite modulator OEM module designed for applications over satellite in full compliance with the DVB-S, DVB-DSNG, DVB-S2 and DVB-S2X standards. One single hardware platform covers the full L-Band range (950/2150 MHz) and IF Band range (50/180 MHz) from 0.05 to 72 MBaud. It is also able to drive a Block Up Converter (BUC) thanks to its high stability 10Mhz reference available on the L-Band RF output signal.

VYP offers a data rate from 0.25 Mbps up to 200 Mbps and content aggregation of up to 4 MPEG-TS multiplex in one satellite carrier via the Multistream feature as defined in the DVB-S2/S2X standard. Our product is totally compliant with latest Carrier ID requirements defined in ETSI 103 129.

VYP offers some free of charge services as a Push Data Service (DualCast) based on MPE, an ACM Contribution (ContribACM) feature that adapts the modulator MODCOD without any video interruption to allow the video transmission to continue under deteriorating satellite link conditions. VYP proposes a very flexible input redundancy between 4 TSoIP and/or 2 TSoASI. VYP includes the DVBS2X Broadcast and DSNG profiles. It means that VYP supports all new MODCOD & the 64 APSK constellation. The new roll off (from 5% to 15% by step of 1%) are available with any satellite standards.

Performance & Reliability
VYP has been designed to meet all ETSI EN 302 307 requirements: part I for DVB-S2 and part II for DVBS2X. All modes of bit rate adaption are possible: PCR adaptation, Padding Insertion and Dummy PL Frame insertion resulting in VYP’s unique automatic flexible rate adaptation. VYP offers a flexible baudrate (from 0.05 to 72 MBaud) to fully feed a 72 MHz transponder. An internal PRBS generator can be used to generate a RF spectrum without any valid signal input. VYP offers, without option, the possibility to receive the incoming MPEG-TS stream either over ASI or Ethernet inputs.

VYP integrates the core technology required to perform high quality modulation based on TEAMCAST expertise. It provides customers with a best in class performance, providing a high SNR value, excellent shoulder levels and lowest phase noise. VYP provides a high performance channel spectrum and in addition to the standard, roll off from 5 to 35% by step of 1% for the all modulation: DVB-S/DVB-DSNG/DVB-S2 and of course for DVB-S2X. This results gives an efficient transmission in 32APSK (DVB-S2/S2X) and 64APSK (DVB-S2X) with lower power.


The user-friendly Embedded Web Browser ensures ease of use and enables full configuration of the modulator, including signal input management, selection of DVB-S, DVB-DSNG, DVB-S2 and DVB-S2X, modulation type (MODCOD) and control of the mute/unmute conditions for the RF output signal. The GUI also offers monitoring of the input stream (i.e. input format & useful bit rate).
