A computing system implemented method is disclosed for distributing data objects in a network of computing nodes. Each node has stored thereon subscription rules defining characteristics of data objects that the particular node may require during processing. The nodes exchange their subscription rules with other nodes in the network. Each node then compares the rules received from other nodes with the attributes of data objects stored on the particular node. Where a rule set matches the attributes of a data object stored thereon, the node marks the particular data object for copying to the node from which the particular rule set was received. The marked data object is then copied to the appropriate node.

An elementary module of a workflow of a system for distributing audiovisual contents is disclosed. Content is received as a succession of segments which are distributed following a transmission of a request and are obtained by an application of a workflow to a portion of a content. The elementary module executes a processing operation of a predefined type of the workflow and comprises: a variable plurality of processing units available for executing the processing operation of the predefined type, the elementary module regularly obtaining information representing each processing unit added to or removed from the plurality, an allocation module able to manage allocations or disallocations of processing units of the plurality according to requests for first data received; and a load management module able to choose, for each request received, at least one processing unit among the processing units allocated for processing second data in order to obtain first data requested.

A media system replaces content in a first sequence of media content. The media system presents the first sequence of media content to an end-user and generates a fingerprint of the sequence of media content. The fingerprint is for comparison with a plurality of reference fingerprints so as to identify the first sequence of media content and determine a reference position within the first sequence of media content. The media system sends a request for a replacement sequence of content to a content replacement system, and receives replacement media content selected based on the identified first sequence of media content. The media system presents the replacement media content to the end-user instead of the first sequence of media content. Presenting the replacement media content begins at a position in the first sequence of media content that is determined based on the reference position.

A content delivery system comprising one or more one management servers comprising one or more processors for executing a code of one or more management agent instances. The code comprising code instructions to monitor a plurality of delivery servers of a distributed network to update dynamically a content record listing a plurality of content objects according to availability parameter(s) of each delivery server, code instructions to receive a content request from (user) client device to retrieve requested content object(s), code instructions to select preferred delivery server(s) from the delivery servers to provide the requested content object(s) to the client device according to analysis of the availability parameter(s) of each delivery server and code instructions to provide the client device with an IP address of the selected delivery server(s) to allow the client device to retrieve the requested content object(s) via a transmission session established with the selected delivery server(s).
