Abstract: A media source, including a sending unit that sends out time-stamped media data packets to one or more receiving media sinks. A timestamp of one of the time-stamped media data packets indicates a time of creation of the one of the time-stamped media data packets. The media source also includes a determining unit that determines a play-out time offset. The media source additionally includes a transmission unit that sends out the play-out time offset to the one or more receiving media sinks once for all time-stamped media data packets of a session.

Abstract: Data transmission system for home-installed data transmission, in particular for home networks or the like, within a building (B) is provided, comprising at least one home-installed data source device or home-installed transmitting device (TD), at least one home-installed data sink device or home-installed receiving device (RD), and at least one home-installed connecting device (CD) for connecting said data source device or transmitting device and said data sink device or transmitting device for data transmission from said data source device or transmitting device to said data sink device or receiving device, wherein home-installed conveying lines/pipes (P) are provided as said connecting device (CD) and wherein said conveying lines/pipes (P) are pre-installed within said building (B).

Abstract: In a digital audio transmission system media data packets (1021, 1022) are sent from a media source (101) to media sinks (e.g. loudspeakers) (1, 2). If a media data packet (1021, 1022) is received by a media sink (1, 2) and contains audio data belonging to an audio signal of e.g. a stereo signal, it is important that this media data packet (1021, 1022) is played-out at the same moment as a media data packet (1021, 1022) containing an audio signal of the same stereo signal received by another media sink (1, 2), i.e. the media data packets (1021, 1022) must be played-out synchronously. To ensure this synchronous play-out of media data packets (1021, 1022) in different media sinks (1, 2), a common play-out time (105) is determined by the media source (101) or the media sink (1, 2) and media data packets (1021, 1022) are buffered in a buffer (1041, 1042) until this common play-out time (105) is reached.

Abstract: According to the present invention, for connecting the different bus systems to each other to build a superior network, a common network layer is provided to which the bus systems are connected for data and/or control exchange via gateway devices. Further, an intelligent gateway according to the present invention is distributed in the network, i.e. on the common network layer to which the gateway devices according to the present invention are connected. So this intelligent gateway can be accessed on all gateway devices. This allows the incorporation of cheap (dumb) gateway devices, which just provide the bus API, i.e. a bus service interface. Device specific (software) modules can run distributed on other intelligent gateway devices or on the intelligent gateway.
