A method for selectively updating a dynamic
manifest file is described, wherein the method may comprise: selecting one or more
metadata elements of a
manifest file used by a
client, the one or more selected
metadata elements being associated with a subset of representations of the set of representations defined in the
manifest file; transmitting a request message identifying the selected one or more
metadata, and, optionally, said manifest file identifier, to a network node, the request message being configured to trigger the network node to generate a response message on the basis of the information in the request message; and, receiving the response message from the network node, wherein the response message comprises: location information, preferably an URL or a part thereof, for retrieving a selectively updated version of the dynamic manifest file used by the
client, wherein the selectively updated version only comprises new segment identifiers associated with the one or more selected metadata elements; or, wherein the response message comprises: update information, preferably a patch, configured to selectively update the dynamic manifest file used by the
client apparatus, wherein the update information only comprises new segment identifiers associated with the one or more selected metadata elements.
