Abstract

The proposed study addresses the inefficiency of traditional manual notice boards and overcomes limitations in prior IoT signage systems, which often rely on small displays, lack multi‑device synchronization, and offer poor update responsiveness. The objective is to develop a network‑based Smart TV notice board using Raspberry Pi 4 connected to an LED TV, with a secure web application and MySQL backend. We implement the system using Embedded C (for display controller) and Python + HTML/JavaScript (for server and web client), enabling real-time communication via WebSocket/MQTT. In prototype testing with 100 sample notices, display latency remains low (2–3 seconds) with 100% successful propagation and CPU utilization under 50%. The result proves the system’s reliability, scalability, and real-time performance. This cost‑effective, energy-efficient solution modernizes campus communication, enabling synchronized notice access on Smart TV, mobile, and laptop devices inviting the research community to further build on its architecture and scalability.
