Encoding Blocks for Digital Video of DVB-S2 Standard with Drone-based Communications

Digital video information has continuously become a dominant portion of data types in the Industrial Revolution 4.0., whose general objectives are securing the information, transmitting with high efficiency, and building real-time system. Among different types of broadcasting standard, the Digital Video Broadcasting - Satellite Second Generation (DVB-S2) is considered a single, very flexible standard, covering a variety of applications for satellite-based communications. Being compatible with multiple input protocols makes it possible to handle many kinds of data such as voice and video. In this article, a design of the encoding blocks for the DVB-S2 system is implemented using the hardware language Verilog. Nonetheless, due to complexity of performing the whole video broadcasting system, only the channel encoding blocks are conducted as being one of the cores of the model. Specifically, three blocks: Cyclic Redundancy Check 8 (CRC8), Scrambling and Bose-Chaudhuri-Hocquenghem (BCH) is conducted. In order to verify the results generated by Verilog, we also use online generator tool as well as C-written code to compare. The time for generating CRC8 and BCH code are 149ns and 388814ns for input of 72 bits and 38688 bits, respectively. In addition, our team also build a drone model to mount board onto it. The results demonstrates that DVB-S2 is suitable for broadcasting in real-time. � 2019 IEEE.
