DVB-GSE Encapsulator and Decapsulator

The DVB-GSE encapsulator and decapsulator IP cores close the gap between network protocols like Ethernet and the physical layer of the DVB family of standards.

The DVB-GSE encapsulator performs the encapsulation of the network layer packets, also referred to as Protocol Data Units (PDUs), into one or more GSE packets, adding control information and performing integrity checks when necessary.  Finally, it provides the data as baseband frames (BBFRAMEs) to the Creonic DVB-S2/DVB-S2X modulator. The Creonic DVB-GSE decapsulator performs the decapsulation of BBFRAMEs, containing one or more GSE packets. As a last step, it extracts the PDUs, i.e. the network layer packets, from the GSE packets and provides it to the user.

• Support for Jumbo FramesThe output of the core perfectly matches the  DVB-S2X modulators both in narrowband (M100 and M400) and wideband (M800) versions
• The input of the core perfectly matches the  DVB-S2(X) Decoders and DVB-S2X Wideband Decoder
• Optional insertion of Frame CRC-32 in the encapsulator
• Low-power and low-complexity design
• AXI4-Stream data interfaces for a seamless integration
• AXI4-Lite interface for configuration and retrieval of status information
• Available for ASIC and FPGAs (AMD Xilinx, Intel, Microchip)

• Applications with the need for encapsulation of IP and other network-layer packets over DVB-S2 or DVB-S2X physical layer frames
