SYSTEMS FOR ALLOWING ANNOTATION IN REAL TIME

摘要

Synchronous content sharing of media assets via an object data model propagated through a star network or a mesh network. Each user device updates a local object data model including information on the status of the media asset delivery, to achieve synchronization with the source data. Updates to the local object data model may be the result of direct connection between a user device and an application server via a network, or the result of indirect connections through peers in mesh networks, where the local object data model is shared through hops between peers in the mesh network if the direct connection is unavailable.

主权项

1. A method for synchronous content sharing, including:
storing in a computing device an object data model representative of a state of a presentation; updating in the computing device the object data model in response to a change in the state of the presentation; through a network connection, sending update information from the computing device to an API server; receiving, at a user device, updates to a local object data model stored at the user device; requesting a star network connection between the user device and the API server; updating the local object data model by periodically pushing updates to the local object data model from the API server to the user device; requesting a mesh network connection between the user device and at least one other user device; when the star network connection fails, updating the local object data model by periodically pushing updates to the local object data model from the at least one other user device in the mesh network, wherein content in the computing device is synchronously shared with the user device.
