Abstract
Abstract A passenger entertainment system of an aircraft utilized to distribute audio and/or video in a digital format throughout a vehicle. The passenger entertainment system includes an Asynchronous Transfer Mode ("ATM") network interconnected to a high speed, serial distribution network propagating information in a predetermined format. Collectively, these digital networks support the broadcast of audio and/or video in real-time as well as actual "video on demand" services.
