Abstract

An aircraft in-flight entertainment system includes a plurality of seat electronic boxes (SEBs) spaced throughout the aircraft. Each SEB is configurable for passing a registration token along to an adjacent SEB. Cabling connects the SEBs together in a daisy chain configuration. Registration circuitry is connected to the cabling for identifying a location of each SEB based upon passing of the registration token among the plurality of SEBs.

sending registration confirmation to the first SEB, the first SEB then passing the registration token to a next sequentially ordered SEB based upon the received registration confirmation,

polling said plurality of SEBs for the next sequentially ordered SEB having the registration token and receiving a response therefrom, and

repeating the sending of registration confirmation and the polling for the next sequentially ordered SEB until a last sequentially ordered SEB has been registered.

12. An aircraft IFE system according to claim 11 wherein said registration circuitry performs the following before polling said plurality of SEBs for the first SEB:

sending a broadcast command to said plurality of SEBs for clearing any existing registrations in said registration circuitry.

13. An aircraft IFE system according to claim 11 wherein said registration circuitry comprises a memory for storing a seating layout image of the aircraft, and the location of the first SEB is assigned based upon the seating layout image;

and wherein the location of the next sequentially ordered SEB is determined with respect to the assigned location of the first SEB.

14. An aircraft IFE system according to claim 13 wherein said registration circuitry comprises:

a control panel display; and
