Abstract
A video display unit (VDU) for an inflight entertainment (IFE) system, and a main circuit board and swappable entertainment processor board for use therein. The swappable entertainment processor board detachably engages with the main circuit board, allowing a main circuit board of a single design configuration to be deployed on VDUs throughout an aircraft (or across a fleet of aircraft) with entertainment processor boards of various design configurations that support different IFE feature sets. In addition to facilitating differentiated IFE services, the present invention permits rapid deployment of new technologies through redesign and swapping of entertainment processor boards. Moreover, the main circuit board may be advantageously designed to accept an industry standard entertainment processor board, which allows an entire shipset of VDUs (or a subset thereof) to be upgraded by simply swapping-in an entertainment processor board compliant with the latest version of the industry standard.
