Abstract
(EN)
A broadcast reception apparatus comprises: a broadcast interface for receiving a service including a program, and signaling information, wherein the signaling information includes media time information of the program being reproduced; a companion screen interface for discovering a companion screen device; and a controller for operating the broadcast interface and the companion screen interface, wherein the controller includes a time synchronization service processor for generating service time information providing data related to a time synchronization between the program and a program being displayed on the companion screen device on the basis of the signaling information, and the companion screen interface transmits the service time information to the companion screen device.
