Establishing a streaming presentation of an event

A system for providing a streaming client with a streaming presentation of an event, the streaming presentation having been obtained by dynamically switching between a plurality of media streams which represent different recordings of the event, the plurality of media streams being accessible from a respective plurality of recording devices recording the event, and the system comprising:

• an input for obtaining source data from the plurality of recording devices, the source data being constituted by content data and/or metadata of concurrent portions of the plurality of media streams, the concurrent portions representing concurrent time periods of the event, each media stream comprising multiple consecutive portions;
• a processing subsystem configured to, for each of the consecutive portions:
• i) apply at least one content quality assessment function to the source data for assigning a content quality score to each one of the concurrent portions, thereby establishing a plurality of content quality scores for the respective plurality of recording devices;
• ii) generate selection data for enabling the streaming client to select, from a manifest, one of the plurality of recording devices which provides access to a selected one of the concurrent portions of a respective media stream, the selected portion having been selected based on a comparison of the plurality of content quality scores, wherein the selection data comprises at least part of the plurality of content quality scores, wherein when generating the selection data, a previous selection of one of the plurality of media streams is maintained when a length of the concurrent portion of the one of the plurality of media streams is below a length threshold;
• iii) format said at least part of the plurality of content quality scores as a metadata stream;
• and
• iv) include address information in the manifest for enabling the streaming client to access the metadata stream and for enabling the streaming client to access the plurality of recording devices;
• and
• a client interface for providing the manifest and the metadata stream to the streaming client.
