Abstract
A method for managing HTTP adaptive streaming of digital content within a real-time multimedia stream player terminal, associated with a terminal for rendering the digital content. The method includes obtaining a description file for the digital content, including a list of time segments of the content each associated with a plurality of content encoding rates; and downloading time segments at one of the encoding rates. The method implements a concomitant rendering, by the rendering terminal, of the digital content and of an element, called main element, belonging to a group including a menu and other digital content. The method implements, during the downloading step, a partial downloading of a preliminary portion of at least some of the time segments, and a rendering, for a duration of one of the time segments, of a picture decoded from the preliminary portion of the corresponding time segment.
