  • Publication number: 20240089165
    Abstract: A domain manager configured to manage and/or configure an audio-video (AV) system but not directly participate in networked media transmission or clock synchronization. The domain manager may include a database; an endpoint manager configured to communicate with the database, the endpoint manager being configured to setup and maintain secure connections to and from media devices and controllers; and at least one management module configured to communicate with the database and provide services to the media devices and controllers. In embodiments, the at least one management module may include at least one of a manager for managing credentials and grouping devices into domains, a device directory for managing device registrations and lookup, and an access controller for managing and/or evaluating access control policy.

  • Publication number: 20230370185
    Abstract: In certain aspects, the present disclosure is related to devices, methods, systems and/or computer-readable media for use in an isochronous media network in which media devices connected to a network employ one or more synchronization signal to regulate or facilitate the transmission of media signals through the network. In certain aspects, the present disclosure is also related to devices, methods, systems and/or computer-readable media for use in a larger unified, or substantially unified, isochronous network created from aggregating local isochronous media networks in which media devices connected to a network employ a one or more synchronisation signal distributed from a local master clock to regulate or facilitate the transmission of media signals.

  • Patent number: 11764890
    Abstract: A networked system is provided for transporting digital media packets, such as audio and video. The network includes network devices interconnected to send and receive packets. Each network device can receive and transmit media signals from media devices. A master clock generates a system time signal that the network devices use, together with a network time protocol to generate a local clock signal synchronised to the system time signal for both rate and offset. The local clock signal governs both the rate and offset of the received or transmitted media signals. The system, which can be implemented using conventional network equipment enables media signals to be transported to meet quality and timing requirements for high quality audio and video reproduction.
