Digital signage network

摘要

A digital signage network employs a common data model and a subscription system to disseminate data gathered from a plurality of data sources to a number of displays. The network nodes interact with each other as content sources, content consumers, or both, with some systems acting as consumers to upstream sources and acting as sources to downstream consumers. The presentation of the data on a digital signage display allows for real-time binding of live data to provide a rich display effect.

1. A digital signage network comprising:
a plurality of content sources, each of the plurality generating content formatted in accordance with a common data model; and at least one distribution node connected upstream to at least one of the plurality of content sources and connected downstream to a plurality of display node devices, wherein the plurality of content sources and the at least one distribution node include a subscription engine for receiving an aggregated subscription request initiated from the plurality of display node devices such that the aggregated subscription request is propogated upstream to the plurality of content sources, and wherein new content corresponding to the received aggregated subscription request is stored in a queue until the new content matches the aggregated subscription request, and when the queued new content matches the aggregated subscription request, the at least one distribution node automatically pushes the new content downstream by at least one of the plurality of content sources from the queue through the corresponding at least one distribution node to the corresponding display node devices, wherein the new content received from said plurality of content sources is divided into ordered content layers, live data is bound to the ordered content layers, threads are created for each of the ordered content layers, and the threads are flattened and rendered by different processors in parallel, and wherein the display node devices are configured to receive and display the rendered, flattened threads.
