Abstract
A method for managing zapping from a first digital content to a second digital content is disclosed. The first and second digital contents are obtained by HTTP adaptive streaming 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. The 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; 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; and downloading the first time segment of the second digital content at the selected rate.
