Abstract: The present disclosure relates generally to media streaming, and in particular to devices (1, 2,3) and methods (4, 5) effecting a collaborative delivery of correlated media streams. Inter alia, a synchronizing node (1) is provided, comprising a processor (11) being configured to: establish (41) a synchronization of one or more source nodes (2) with respect to the synchronizing node (1) based on a heartbeat; receive (42) one or more packets from a number of the one or more source nodes (2) in accordance with the established synchronization; process (43) the one or more received packets in dependence of a compliance with the heartbeat; and maintain (44) the compliance with the heartbeat. This provides a collaborative delivery scheme enabling correlated media streams/packets to be delivered and to arrive at their destination "together" to meet the application requirement, without relying on global clock synchronization of all nodes and with minimum delay.

Abstract: An electronic controller of a restraint control system for a vehicle comprises an electronic control unit including a first serial interface. The electronic controller also comprises a communications controller including a second serial interface and a plurality of PSI5 (Peripheral Sensor Interface 5) digital communications interfaces. Each of the first and second serial interfaces are Serial Peripheral interfaces (SPI) in direct communications with one another, and the digital communications interfaces are each configured to communicate with a remote sensor. The communications controller is configured to transmit a voltage sync pulse to each of the remote sensors via the PS15 digital communications interfaces in response to a synchronization command received from the electronic control unit via the serial interconnection. The voltage sync pulses on each of the PSI5 interfaces may be staggered and non-overlapping to reduce EMI production and to reduce the current load of the electronic controller.
