Encoding blades design makes it convenient to change encoding module between any video formats HD SDI, HDMI, YPbPr, CVBS, AES . It is also 1 channel ASI input for external TS pass or multiplexing.
It outputs DVB-S/S2/S2X RF (IF Optional – model specific) and ASI. It supports currently required CID Carrier ID

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.
Background
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. 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:
