Abstract: Systems and methods of generating a synchronized media content presentation using a plurality of media output systems communicably coupled to a respective plurality of network connected platforms are provided. A first network connected platform receives an IEEE 802.1AS master timing signal generated by “Grand Master” timing circuitry disposed in a second network connected platform. IEEE 802.1AS application service circuitry disposed in the first network connected platform determines an offset between a local timing signal and the receive master timing signal. Talker circuitry disposed in the first network connected platform synchronizes a media content presentation to the master timing signal and communicates a media/master timing signal synchronization signal to each of the network connected platforms. The media/master timing signal synchronization signal includes data representative of a media start location and a media start time referenced to the master timing signal.

Abstract: Approaches provide for a voice communications device to control, refine, or otherwise manage the playback of media content in response to instructions, such as spoken instructions. For example, the voice communications device receives input data associated with a command, such as a request to begin media playback. Accounts corresponding to users associated with the command are identified and one or more refinements extracted from the input data are used to filter content, such as from respective content catalogs or via trained models associated with the users. Determined content is generated that includes content from each of the content catalogs or trained models associated with the users. Thereafter, the voice communications device can initiate media playback.
