This standard is an addition to the group of standards GOST R 57870.1, GOST R 57870.2, GOST R 57870.3, GOST R 57870.4, which defines the rules for using content for additional media devices displayed on a TV device. This standard defines mechanisms for synchronizing the timeline between a presentation on one device and associated synchronized content on another device. These mechanisms provide coordinated control of the playback of two independent media streams on two independent players. This standard normalizes the exchange of information between two players through a home network. This standard sets the parameters for the processes of identifying and synchronizing content and triggering events on a television device (TV device) with content presented on a personal device (smartphone, tablet, player). The requirements of this standard should be taken into account when developing, manufacturing and operating DVB devices, as well as when developing, designing and operating software for DVB networks
