Abstract: A controller (16) for controlling a player (14), the player (14) being configured to: play back segments of a data stream stored in a buffer (12), and request at least one segment of the data stream to be transferred from a peer-to-peer cache (10) to the buffer (12) whenever an amount of data pending for playback in the buffer (12) is less than a data threshold, wherein the peer-to-peer cache (10) stores segments of a data stream in a format adapted for transfers in a peer-to-peer network; wherein the controller (16) is configured to: be set into a dynamic mode wherein the controller (16) alternately sets the data threshold to first value and to a second value greater than the first value, and into be set into a static mode wherein the controller (16) maintains the data threshold at the second value; and switch between the dynamic mode and the static mode whenever predefined conditions are met.

Receiving a request for a segment from the player; b. Providing, in response, said segment from the first buffer (M1) upon expiry of a response deadline defined with respect to said ABR logic of the player.
