Abstract: A method for processing a media stream is proposed, which comprises, at a media distribution unit comprising a processor: upon receiving, from a player device, a request for a media data segment of the media content stream, determining a media data chunk of the one or more media data chunks that corresponds to the segment and is available for distribution to the player device; determining a bootstrapping file of the one or more bootstrapping files that corresponds to the media data chunk, wherein the I-type image of the bootstrapping file corresponds to an image of a media data chunk that precedes the media data chunk in the media data segment; generating a response media data chunk by combining the media data chunk and the bootstrapping file; and serving the request based on the response media data chunk by sending the response media data chunk to the player device.

Abstract: A method for managing computational resources allocated for encoding of one or more multimedia content streams for distribution in dynamic mode to viewing devices through a distribution network is proposed, which comprises, by a processing node of the distribution network: obtain, for a multimedia content stream corresponding to a channel distributed to the viewing devices, a value of a computational resource allocation criterion, wherein the computational resource allocation criterion comprises an audience measurement for the corresponding channel; and determine, based on the computational resource allocation criterion, an allocation of computational resources of a computing platform configured for encoding the multimedia content stream.
