Abstract
A node (14) for a content delivery network (12), CDN is provided. The CDN (12) is configured to store a plurality of first media segments and a plurality of second media segments different from the first media segments. The node (14) interacts with a device (20), the node (14) includes a reception module (24) configured to receive a manifest request, from the device (20), for media content corresponding to the plurality of first media segments (S100). The node includes a manifest module (30) configured to generate a manifest (48) for the requested media content. The manifest (48) indicates a plurality of modified media segments (50) including the plurality of first media segments and at least one of the plurality of second media segments (S102). The plurality of modified media segments (50) have uniform segment lengths with respect to each other. The node includes a transmission module (22) configured to transmit the manifest to the device for media playout (S104).

23. A device for media playout of content from a content delivery network, CDN, the CDN configured to store a plurality of first media segments and a plurality of second media segments different from the first media segments, the device comprising:
-
a processor; a memory, the memory containing instructions executable by the processor that are configured to cause the device to; detect a network condition; determine at least one suggested media segment characteristic for media playout, the at least one suggested media segment characteristic being based on the detected network condition; and transmit a manifest request for media playout of the plurality of first media segments, the manifest request including the at least one suggested media segment characteristic. - View Dependent Claims (24, 25, 26, 27)
