CLAIMS

1. A domain manager comprising:

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;

wherein the at least one management module includes 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.

2. The domain manager of claim 1 , wherein domain manager is configured to manage and configure an audio-video (AV) system but does not not directly participate in networked media transmission or clock synchronization.

3. The domain manager of claim 1, wherein the domain manager is virtualized and/or provided as a service delivered by cloud technology.

4. The domain manager of claim 1 , wherein the domain manager enables one or more of networked media distribution over routed networks, management of large scale media networks, and fault tolerant media networks.

5. The domain manager of claim 1, wherein media flows and clocking are maintained even if the domain manager is temporarily unavailable because the system is configured to detect and switch to another unicast-capable master clock (from the previously selected candidates) even if the domain manager is not present.

6. The domain manager of claim 1 , wherein the domain manager incorporates a device metadata database and associated processes that are reactive to changes in device metadata.

7. The domain manager of claim 1 , wherein the domain manager provides prompt notification to controllers and other devices when media devices are connected and disconnected from the network, or when media device metadata changes.

8. The domain manager of claim 1, wherein the domain manager allows controllers to discover a subset of the media devices in a large network, where that subset is defined using flexible queries based on device metadata.

9. The domain manager of claim 1 , wherein the domain manager facilitates network management by centralizing information and/or control of devices in a networked media system.

10. The domain manager of claim 1 , wherein the domain manager is implemented in software and is configured to manage clocking configuration and media configuration

11. The domain manager of claim 1 , wherein the domain manager provides the ability for a network administrator to define access control policies.

12. The domain manager of claim 1, wherein the domain manager provides the ability for a network administrator to assign access control policies to security principals (for example users (e.g., with associated passphrases/keys), device keys (for controller embedded within media devices), and/or controller API keys (e.g., for controllers that do not support the ability for user login - such as a wall mounted controller)).

13. The domain manager of claim 1, wherein the domain manager provides the ability to evaluate access control policies on the domain manager by forwarding configuration messages via the domain manager to permit complex, fine grain access control policies to be enforced.

14. The domain manager of claim 1, wherein the domain manager provides the ability for access control policies to be pushed from the domain manager to media devices so they can be cached and evaluated on the device without requiring the configuration message to be forwarded via the domain manager.

15. The domain manager of claim 1 , wherein the domain manager provides the ability to manage a database of users, passwords, roles, and/or access keys that can be used to assign access controls.

16. The domain manager of claim 1 , wherein the domain manager provides the ability to connect to an external sign-on service such as active directory to authenticate and manage users.

17. The domain manager of claim 1 , wherein the domain manager improves the collection and display of statistics and performance information in one or more of the following manners: acting as a centralized storage for this information; collecting both live and historical information; interfacing via appropriate APIs with external data analytic services to better analyze and visualize this information; using appropriate data storage architectures such as time series databases so that the data can be easily analyzed and aggregated; generating alerts in the event of errors or performance information reaching particular thresholds; and converting alerts to a form such as simple network management protocol (SNMP) so they can be received by third party network management tools.

18. The domain manager of claim 1 , wherein a single domain manager can manage multiple domains.

19. The domain manager of claim 1 , wherein the domain manager may be able to handle both legacy and domain-aware devices.

20. The domain manager of claim 1 , wherein the domain manager further comprises a component that can re-time media signals between two clock domains and generate a tie line packet stream.

21. The domain manager of claim 1 , wherein the domain manager of a first domain is configured to assume responsibility for configuring a tie-line source, including which media signals are included within the tie line.

22. The domain manager of claim 1 , wherein the domain manager manages the creation and deletion of domains, generation of credentials and/or grouping of devices into domains.

23. The domain manager of claim 1, wherein the domain manager configures non-domain-aware device's clock domain to match the systems domain's clock domain using an insecure connection

24. The domain manager of claim 1 , wherein the domain manager is a high availability domain manager.

25. A method for providing automated configuration of multi-subnet synchronization systems as described herein.

26. A method for providing active management of a large scale media system as described herein.

27. A method for providing fault tolerant operation of a large scale media system wherein a central management server may not be present, (e.g. devices sensibly caching and operating with known good parameters etc.) as described herein.

28. An apparatus/system for providing automated configuration of multi-subnet synchronization systems as described herein.

29. An apparatus/system for providing active management of a large scale media system as described herein.

30. An apparatus/system for providing fault tolerant operation of a large scale media system wherein a central management server may not be present, (e.g. devices sensibly caching and operating with known good parameters etc.) as described herein.
