1. A media reproducing device comprising:

  • a media data output element operable to output media data stored on a storage medium to a media data presentation unit;

    a receiver operable to receive a sequence of video images from a video camera via a communications link; and

    a user detector operable to detect, by analysis of the sequence of video images received from the video camera via the communications link, whether a user is attending to a presentation of the media data by the media data presentation unit, the user detector being operable to analyse an image monitor area of each received video image so as to detect whether the user is attending to the presentation of the media data by the media data presentation unit, and the image monitor area corresponding to an image region that is smaller than the field of view of the video camera,in which;

    the user detector is operable to;

    generate motion vector tracks associated with movement of objects within the sequence of received video images; and

    detect whether the user is attending to the presentation of the media data in dependence upon a relationship between positions of the motion vector tracks and the image monitor area; and

    if the detector detects that the user is not attending to the presentation of the media data, the detector is operable to store a bookmark associated with a motion vector track which indicates that the user is not attending to the presentation of the media data, the bookmark being indicative of a point from which presentation of the media data can resume.
