Sistema de TV digital: análise da qualidade do sinal de transmissão de vídeo e áudio via mochilink 4g na cidade de Manaus

Abstract

In Brazil, the digital open television signal provides the population with free access to high-quality audio and video. However, open TV faces challenges, particularly due to the rise of streaming services and cable TV, which offer on-demand content and interactivity. Although SmartTVs integrate internet functionality, their interactive experience depends on broadband connections and applications, limiting accessibility for some audiences. Additionally, simultaneous use of mobile devices, such as smartphones and tablets, often distracts viewers, reducing engagement with traditional programming. To address these challenges, 4G mochilink technology has emerged as a strategic solution, especially for communication professionals who require mobility and high-quality real-time transmission. This technology enables external live broadcasts in locations with limited internet infrastructure, particularly valuable in regions like Manaus, with geographical and network coverage challenges. This study proposes an analysis of video and audio signal quality transmitted via 4G mochilink in Manaus, assessing its effectiveness as a mobile transmission alternative for digital open TV. By utilizing mochilink, the aim is to expand open TV’s reach and provide greater accessibility in areas with limited internet infrastructure. The research seeks to provide technical data to optimize 4G mochilink use for live broadcasts, supporting the expansion of digital TV’s reach and quality.
