1. A content receiving node in a digital signage network for receiving content from upstream nodes in a digital signage network, the content receiving node comprising:

  • a content request engine indirectly connected to a content source and configured to generate a subscription request requesting content from the content source via at least one of the upstream nodes that are each directly connected to the content source, the upstream nodes being connected to each other and configured to transmit data between each other;

    a receive queue configured to receive requested content from the at least one upstream node in the digital signage network, wherein all of the requested content having different types of data received by the receive queue is stored in a common data format differentiated on the basis of metadata associated with the content;

    a processor configured to process and aggregate content in the receive queue into aggregated user viewable information;

    a transmit queue in communication with the content request engine and at least one additional content receiving node, the transmit queue configured to transmit the aggregated user viewable information to the content request engine and the at least one additional content receiving node;

    a display configured to receive the aggregated user viewable information from the transmit queue and display the received information; and

    a network discovery tool configured to request, through the content request engine, nodal information from other nodes in the digital signage network, the nodal information including a system configuration of other nodes in the digital signage network and the operational status of elements of the other nodes in the digital signage network,wherein the content request engine aggregates subscription requests for corresponding content receiving nodes connected to the content request engine, and transmits an aggregated subscription request to the at least one upstream node.
