Design and Implementation of a Digital Video Broadcasting System Using Software-Defined Radio

Abstract

In this paper, we present the design and implementation of a digital video broadcasting system using software-defined radio. The system aimed to broadcast a live video feed wirelessly from one computer to another. The design made use of a USRP B210 for transmission utilizing GNU radio companion blocks imported into a python script designed to transmit the live video feed and an RTL SDR dongle for the reception which is done using a VLC player. The developed system achieved a 2K mode DVB-T transmission on a 6.587 MHz bandwidth across a maximum range of 20.4 meters. The maximum range was dependent on the power gain of the transmitter, which is the frontend capability of the software-defined radio. Therefore, this makes improvement and future-proofing easy.
