Abstract: An entertainment device comprises communication means operable to receive media data from a media data source, storage means operable to store the received media data, in which the storage means limits the duration of access to the media data which was received from the media data source.

Abstract: Game processing apparatus comprises means for indicating successive target actions to be executed by a user, each target action having an associated target time of execution; and scoring logic in which detected user actions are compared with the target actions, the storing logic comprising: an input arrangement by which user actions may be detected; means for comparing a detected sequence of user actions with a sequence of target actions; and means for detecting a timing offset between the sequence of user actions and a corresponding sequence of target actions; in which the comparison of subsequent user actions with respective target actions is arranged to apply the timing offset as a relative displacement between the detected user actions and the target times.
