Courier electronic devices are used to transport seat video display unit (SVDU) operating system (OS) code updates from a content operation center to onboard a vehicle. The OS code used by the SVDUs is updated based on the OS code update to generate an updated OS code, which is used to curate entertainment content files from a mass storage device for selection among by passengers for their consumption through the SVDUs. Entertainment content files may also be selected by the content operation center based on passenger characteristic information and loaded onto the courier electronic devices for transport onboard the vehicle for transfer to the S VDUs to update the entertainment content that is made available for selection by the passengers. The courier electronic devices may be used to facilitate transportation of other information between the SVDUs in the content operation center.
