POSI

This project was undertaken to build an intelligent dynamic ad delivery platform that delivers real-time optimized marketing messages to consumers through a nationwide convenience store network. TOSKY developed a scheduling engine that maximizes advertising efficiency by precisely targeting ad exposure by region, time, and specific schedules. Considering the unstable network conditions in convenience store field environments, the technical core is the implementation of a 'zero-downtime service architecture' that ensures uninterrupted content playback under any circumstances. The solution flexibly adapts to various Android-based screen specifications and achieves agility through an online update system that enables real-time video and image replacement. Additionally, a self-diagnostic function that checks the operational status of each ad module at second-level intervals was implemented, completing a monitoring environment that enables immediate maintenance through real-time alerts to administrators when anomalies are detected.
