A system and method for distributing digital content on-demand in a common carrier environment, such as an airplane, are disclosed. The present invention employs a combination of low power RF (e.g., WLAN/Bluetooth) and digital data broadcast (e.g., DVB-T) technology to distribute digital content to passengers in an airplane cabin. In an advantageous embodiment, a mobile multimedia terminal (or, alternatively, a fixed seat-back terminal), with a WLAN or Bluetooth link to a content server aboard the plane is used by a passenger to request digital content such as movies, music, games, etc. In response, the server transmits the requested content to the passenger's device via a DVB-T connection. The elimination of a wired connection for each of, for example, 400+ passengers in a Boeing 747, decreases the overall weight of the system and thus reduces fuel costs. A mechanism is also disclosed for quickly updating content in the airplane's server via a DVB-T connection while the plane is at a gate receiving flight and operational data for its next flight.
