Key Outcomes

Increased passenger satisfactionNew revenue models enabledFaster content updates

Business Challenge

Passengers expected a modern media experience even when a vehicle had intermittent or no internet connectivity. Conventional streaming could not guarantee playback in transit, and operators needed a controlled way to prepare, distribute, expire, and report on a changing catalog across onboard systems. The experience also had to remain lightweight on passenger devices and continue to function when the connection to central services disappeared.

Solution Overview

DIATOZ delivered an offline-first infotainment platform that synchronizes an approved media catalog to onboard storage before passengers need it. Lightweight client applications browse and play locally available content, avoiding dependence on a live external connection. An administrative dashboard manages titles, metadata, availability windows, and distribution status, while usage events are retained locally and synchronized when connectivity returns. This separation between central catalog management and onboard delivery supports reliable playback without giving up operational visibility.
