Abstract (en)

[origin: WO2021089942A1] The invention meets this need by providing a method for managing zapping from of a first digital content to a second digital content. Said first and second digital contents are obtained by HTTP adaptive streaming (HAS) by a multimedia stream reader terminal and are each associated with a description file comprising a list of time segments of the content, each time segment being associated with multiple encoding rates of the content. Said zapping management method involves: - receiving a request to zap from the first digital content to the second digital content; - obtaining the description file of the second digital content. According to the invention, such a method also involves: - selecting a rate for encoding a first time segment of the second digital content to be downloaded, on the basis of a resource constraint obtained by the multimedia stream reader terminal and on the basis of a target zapping time; - downloading said first time segment of said second digital content at the selected rate.
