Abstract

A method of dynamically preparing a media clip for delivery from a server to a client is provided. Media attributes comprising media playback formats compatible with the client are provided to the server. A request is made by the client to provide a media content item at a specified starting time, and the server identifies a source where a media content file related to the selected media content item is located. The server obtains the media file from the source, and obtains a transcoded media segment file having a playback format compatible with the client media attributes. The transcoded media segment file may further be prepared in a transport format that is compatible with transport format media attributes of the client device, and a location of the prepared transcoded media segment file may be communicated to the client for the client to access the media segment.

Dependent claims

A computer implemented method of dynamically preparing media content for delivery from a server to a client, said client comprising a client device and a media application for providing media playback on said client device, said computer implemented method comprising the steps of:

receiving media attributes from said client, said media attributes comprising one or more playback formats compatible with said client and one or more transport formats compatible with said client;
receiving from said client a request to provide a media segment comprising a selected segment of a selected media content item, said request defining a starting offset of said media segment;
identifying a source where a media content file relating to said selected media content item is stored;
obtaining said media content file from said source;
dynamically transcoding the media content file to generate a transcoded media segment file comprising a transcoded segment of said media content file, wherein said transcoded media segment file comprises a playback format selected from said media attributes;
selecting a transport format from said media attributes;
preparing said transcoded media segment file for delivery according to said transport format.
