AI Technical Summary
Technical Problem
DVB-S2X satellite communication systems face challenges in maintaining network synchronization due to dummy frames generated when input stream data rates are lower than the transmitter's throughput, leading to issues in bidirectional satellite networks.
Method used
A method for a transmitting device that includes distinguishing and storing GSE packets and null packets efficiently within a code buffer using adaptive coding and modulation (ACM) commands, allowing for fast processing and minimizing hardware implementation area.
Benefits of technology
Enables the transmitting device to accommodate various formats while suppressing hardware implementation area and ensuring fast processing, thereby maintaining network synchronization in DVB-S2X systems.

Abstract
A transmission method of a transmitting device in a satellite communication system may include the steps of: acquiring a first adaptive coding and modulation (ACM) command and a first generic stream encapsulation (GSE) packet; checking whether the free space of a code buffer is greater than or equal to the size of the first GSE packet or the size of the first null packet; distinguishing the first GSE packet and the first null packet using the first ACM command based on the check; storing the first GSE packet in a space allocated between the starting address of the GSE packet and an address increased by the size of the first GSE packet; and storing the first null packet in reverse order in a space allocated between the last address of the null packet and an address decreased by the size of the first null packet.
