A method for processing a media stream is proposed, which includes, at a media distribution unit including a processor and first and second memories for storing media data. The first memory stores media data chunks of the media stream which are separately addressable media data objects for memory read in the first memory. The second memory store media data fragments of the media stream which are separately addressable media data objects for memory read in the second memory, the fragments respectively including one or mode media data chunks: receiving a request related to media data, determining, based on the received request, a descriptor of data to be generated to serve the request, based on the descriptor, retrieving first data from the first memory, and second data from the second memory, and generating data to be generated to serve the request based on the first data and the second data.

Systems, apparatuses, methods, and software for using a network to efficiently distribute media content assets from a virtually unlimited content library and/or other storage to a plurality of client devices, as well as bi-directional local content sharing between head ends, and dynamic distribution and generation of media content assets within the network.

An elementary module of a workflow of an audiovisual content distribution system, each content being received by a terminal in the form of a succession of segments, each segment being distributed to the terminal following transmission of a request by terminal and being obtained by an application of a workflow to a portion of content. The elementary module executes a processing of a predefined type and comprises: a variable plurality of processing units available for executing said processing; a scaling module, able to determine, using a first model, a number of processing units to be allocated for an implementation of a set of processing operations requested of said elementary module; and a load management module able to choose, using a second model, for each processing operation requested, one processing unit among processing units allocated by the scaling module for performing processing, each model being a neural network of the deep learning type.

A content provider in a content distribution system may be configured to reduce latency in a content distribution system by storing multiple frames from a sequence of frames in different buffers and encrypting, in parallel, the frames stored in the different buffers. For example, the content provider may encrypt each buffer via a different instruction pipeline of a processor.

A distributed video management system that allows for monitoring a camera allocation parameter and dynamic reallocation of video cameras to available camera nodes in response to detecting a change in the allocation parameter including selectively dropping at least one camera from the system based on a priority of the camera. The change in allocation parameter may be due to a number of potential contexts including a change in availability of camera nodes, a change in the nature of the video data captured, a change in computational load, or other change that results in a change in allocation parameter. The disconnection or “dropping” of a camera may be temporary in response to an increase in computational load on the system. The use of priority values of the cameras may allow for sufficient camera coverage to be provided by the system while maintaining processing of video data from higher priority cameras.

In various embodiments, domain name system (DNS) servers are implemented on a content distribution network (CDN) infrastructure in order to facilitate centralized control of traffic steering. Each server appliance in the CDN infrastructure acts as both an authoritative DNS nameserver and a dynamic request proxy, and each such server appliance is assigned to one of multiple cloud computing system regions. The assignment of server appliances to cloud regions is based on latency measurements collected via client application probes and an optimization that minimizes an overall latency experienced by the client applications subject to constraints that the maximum traffic to each cloud region is less than a capacity constraint for that region, the maximum deviation of traffic to each cloud regions at any point in time is less than a given percentage, and the maximum deviation of traffic between direct and indirect paths is less than a given percentage.

In general, embodiments of the present invention provide systems, methods and computer readable media for a universal relevance service framework for ranking and personalizing items.

Some embodiments relate to a content matching system (101) comprising a first device (100), a matching server (300), and a second device (200). The content matching system enables the second device to consume content matching with content which is consumable on the first device, even if the first and second devices do not have access to the same streaming service.

A server in a content delivery network (CDN) receives a request for a web page of a domain handled by an origin server. The server retrieves the web page and the web page references a video. The server retrieves a file that indicates a list of locations of the domain in which segments of the video are located. The server fetches at least an initial portion of the segments. The server receives a request for the video. The server transmits to the requester at least the initial portion of the segments. The server receives a subsequent request of a different portion of the segments. The server transmits a response to the requester that instructs the requester to transmit the request for the different portion of segments to a second server in the CDN.
