Abstract

There is disclosed a streaming technique in which a distributed playback, DP, master device receives a media stream from a content provider and transmits the media stream to a plurality of DP client devices. The DP master device may follow different policies. In case one DP client device has not a level of security sufficient for a particular quality, one policy provides that the stream is degraded, while another policy provides that the stream is to be transmitted by a content provider at a reduced quality.
