DVB-GSE Encapsulator and Decapsulator

Overview

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.

Key Features

Compliant with ETSI TS 102 606-1 V1.2.1 (Annex D, DVB-GSE Lite)
Support for multi-protocol encapsulation (IPv4, IPv6, MPEG, Ethernet, etc.)
Fragmentation of IP datagrams or other network layer packets over baseband frames (BBFRAMEs) to support ACM
Support for single stream systems
Support for VLSNR mode in Narrowband
Support for 3-byte and 6-byte Labeling and Packet Filtering
Support for Jumbo Frames.

Benefits

The output of the encapsulator core perfectly matches the Creonic DVB-S2X Modulators
The input of the decapsulator core perfectly matches the Creonic DVB-S2/DVB-S2X Decoders
Automatic 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 (Xilinx, Intel, Microchip)
