<p>A media navigation system provides a user interface for navigating and interacting with streamed media objects, including video. The system may employ media markers representing time locations within a media file in addition to images or other representations derived from the media object. The system displays a tile layout representing a sequence of the media at an interval comprising a set of sub intervals corresponding to the tiles, and enables a user to click on the tiles to navigate to a next set of tiles which correspond to a different interval, and which replace the currently displayed tiles on the display. Navigation can include zooming in (smaller interval), zooming out (larger interval) and 'panning' (preceding or succeeding interval) at arbitrary intervals. Individual tiles may also include visual indicators of relative importance or activity such as the number of comments associated with a sub interval.</p>
