Low-Cost remote monitoring station from standard ISDB-Tb of DTT using SDR

Abstract

This paper analyzes the design of a low-cost remote station for the monitoring of the digital terrestrial television channels of the Brazilian Japanese ISDB-Tb (Integrated Services Digital Broadcasting) using software-defined radio and HD decoding hardware (High Definition). The purpose of this station is monitoring the quality of the digital radiofrequency signal received according to the values obtained in the EVM measures (Error Vector Magnitude), BER (Bit Error Rate), MER (Modulation Error Rate) and Reception Power of the remote station, these parameters will help to determine errors in transmission, audio quality and HD video of the digital signal transmitted by the local TV channels. This system will allow operators of local television channels, the state telecommunications regulatory agency, and researchers in general to acquire valuable information through public access in the internet cloud to view the real-time reception quality of an HD channel and the digital radiofrequency parameters of DTT (Digital Terrestrial Television).
