Method and IPTV server for enabling playout of one or more media objects

摘要

A method and an IPTV server (302) for enabling playout of one or more media objects for a subscriber. A current connection state and capabilities are maintained in the IPTV server for a set of devices (304, 304a) associated to the subscriber. The IPTV server further sends (3:3) a list of the devices to a first device (300), comprising current connection states of the devices. When the IPTV server receives from the first device a first indication (3:4) indicating a wanted media object and a second indication (3:5) indicating a selected second device (304), the IPTV server sends (3:6) a download instruction with a media reference to the selected second device. The download instruction instructs the second device to download and prebuffer (3:7) data of at least an opening part of the wanted media object based on the media reference. Thereby, a user can start playout of the wanted media object on the second device immediately without having to wait for session setup and downloading of enough data for playout.
