Satellite DVB-S/S2 DVB-S2X Modulators with RF CID – Carrier ID



Thor Broadcast’s standalone modulator that has been made to abide by DVB-S2X standards
(EN302 307-2) which is a third generation broadband satellite telecommunication standard that
integrates ASI and IP inputs and modulate them into a DVB-S/S2/S2X IF output.
This 1-U IP input Chassis supports BISS scrambling for easy signal distribution. It also comes
standard with 4 ASI inputs (3 ASI are backups) and a 100mb. The S2X modulator can come with
CID, this is optional, and must be ordered as such.
This Modulator is the newest S2X standard used in a wide variety of application like broadcasting,
news services, broadband satellite applications. Fully compliant with DVB-S (EN300 421), DVB-S2
(EN302 307-1) and DVB-S2X (EN 302307-2) standards.

DVB-CID is a digital satellite transmission system that describes the modulation, channel coding and signalling protocol intended for the identification of the host carrier.

The system has been optimized for satellite applications including DVB-S, DVB-S2 and DVB-DSNG, but can be applied to any continuous transmission by satellite.

The DVB-S/S2/S2X modulator also includes the DVB-CID digital signal, each broadcast carrier (one carrier, one DVBCID
signal). The minimum content of the Carrier ID is the DVB CID Global Unique Identifier (GUI). This GUI is unique
for each equipment manufacturer and is generated based on the unique MAC address of the modulator. Thanks to
this GUI value, it is easy to identify the modulator used to generate the interfering carrier and thus to recognize the
cause of the interference. This is an important tool to stop or at least reduce interference between satellite signals.
Additionally, the DVB-CID message may contain other information that is configurable by the user, such as GPS
coordinates, contact phone numbers, etc., to simplify and speed up the process to stop the interference event.
The DVB-CID system has been optimized for DVB satellite applications; however it can be applied to any continuous
satellite transmission. Adding the DVB-CID signal has no impact on the link budget

DVB-S2X – S2 Extensions
Second Generation Satellite Extensions
What is DVB-S2X?
DVB-S2X is an extension of the DVB-S2 specification that provides additional technologies and features. DVB-S2X
has been published as ETSI EN 302 307 part 2, with DVB-S2 being part 1. S2X offers improved performance and
features for the core applications of DVB-S2, including Direct to Home (DTH), contribution, VSAT and DSNG. The
specification also provides an extended operational range to cover emerging markets such as mobile applications.
DVB-S2 has been specified about 10 years ago with a strong focus on DTH. Since then, new requirements have
come up and DVB-S2X provides the necessary technical specifications. This work was done by the DVB Technical
Module sub-group on satellite chaired by Dr Alberto Morello (RAI), who also led the work on DVB-S2. S2X supports
significantly higher spectral efficiency for the Carrier to Noise Ratios (C/N) typical for professional applications such as
contribution links or IP-trunking. It also supports very low C/N down to -10 dB for mobile applications (e.g. maritime,
aeronautical, trains, etc.).
How does it work?
DVB-S2X is based on the well-established DVB-S2 specification. It uses the proven and powerful LDPC Forward Error
Correction (FEC) scheme in combination with BCH FEC as outer code and introduces the following additional elements:

-Smaller roll-off options of 5% and 10% (in addition to 20%, 25% and 35% in DVB-S2)
-A finer gradation and extension of number of modulation and coding modes
-New constellation options for linear and non-linear channels
-Additional scrambling options for critical co-channel interference situations
-Channel bonding of up to 3 channels
-Very Low SNR operation support down to -10 dB SNR
-Super-frame option
-This results in the following spectral efficiencies for DVB-S2X compared to DVB-S2:
