Abstract
An inflight entertainment system includes video display units that communicate with user terminals through Bluetooth signaling and include a network interface communicating with a content server and a satellite network interface and/or a ground network interface. A time reference message is received which contains a master time reference from the satellite network interface and/or the ground network interface. A local time generator is updated based on the master time reference. Rate request messages are received from the user terminals containing indications of time broadcast rates requested by the user terminals. A scheduled time broadcast rate is determined based on the indications of the time broadcast rates requested by the user terminals. The video display unit transmits, through a Bluetooth transceiver at time instances which are determined based on the scheduled time broadcast rate, broadcast time messages that each contain an indication of a present local time of the video display unit.
