Elementary module of a system for distributing an audiovisual content

A processing method executed by an elementary module executing a predefined type of processing in at least one workflow of a system for distributing audiovisual contents stored or produced live by sources to display terminals, each distribution of content taking place in the form of files, referred to as segments, each segment distributed to a terminal having been the subject of a request transmitted by said terminal and resulting from an application of a workflow to a content portion requested by the request, wherein the method comprises:

• receiving at least one request for first data, each request comprising information representing a workflow to be applied to a portion of a content corresponding to a segment requested in a request by a terminal in order to obtain said first data and information representing configuration parameters to be applied to at least one processing unit in order to generate the first data;
• extracting the information representing the configuration parameters contained in said application and transmitting a request for second data to a source or to a unit preceding the elementary module in the workflow determined from the information representing the workflow, said second data corresponding to said portion processed or not by one or more units preceding the elementary module in the workflow;
• determining whether one or more processing units of the elementary module must be allocated or disallocated and allocating and/or disallocating at least one processing unit when necessary according to the request or requests received;
• each processing unit belonging to a plurality of processing units available for executing the processing of the predefined processing type, the elementary module regularly obtaining information representing each processing unit added to or removed from said plurality;
• choosing, for each request, at least one processing unit among the processing units allocated and activating each chosen processing unit so that it applies the predefined type of processing to the second data on reception of the second data, each processing unit taking into account the information representing the configuration parameters corresponding to the processing that it must execute;
• and,
• for each application, transmitting the first data when they are available to a unit that sent the request for said first data;
• each processing unit not keeping any information concerning a processing once the processing has been carried out.

A non-transitory storage medium having stored therein;

• a computer program comprising instructions that, when executed by a processor, performs a processing method, the processing method being executed by an elementary module executing a predefined type of processing in at least one workflow of a system for distributing audiovisual contents stored or produced live by sources to display terminals, each distribution of content taking place in the form of files, referred to as segments, each segment distributed to a terminal having been the subject of a request transmitted by said terminal and resulting from an application of a workflow to a content portion requested by the request, wherein the method comprises:
• receiving at least one request for first data, each request comprising information representing a workflow to be applied to a portion of a content corresponding to a segment requested in a request by a terminal in order to obtain said first data and information representing configuration parameters to be applied to at least one processing unit in order to generate the first data;
• extracting the information representing the configuration parameters contained in said application and transmitting a request for second data to a source or to a unit preceding the elementary module in the workflow determined from the information representing the workflow, said second data corresponding to said portion processed or not by one or more units preceding the elementary module in the workflow;
• determining whether one or more processing units of the elementary module must be allocated or disallocated and allocating and/or disallocating at least one processing unit when necessary according to the request or requests received;
• each processing unit belonging to a plurality of processing units available for executing the processing of the predefined processing type, the elementary module regularly obtaining information representing each processing unit added to or removed from said plurality;
• choosing, for each request, at least one processing unit among the processing units allocated and activating each chosen processing unit so that it applies a predefined type of processing to the second data on reception of the second data, each processing unit taking into account the information representing the configuration parameters corresponding to the processing that it must execute;
• and,
• for each application, transmitting the first data when they are available to a unit that sent the request for said first data;
• each processing unit not keeping any information concerning a processing once the processing has been carried out.
