NAVIGATING WITHIN A MEDIA ITEM
First Claim
1. A method for user-controlled navigation within a media item comprising a sequence of elements, the method comprising:
- defining a line or curve for controlling the navigation;
defining a transfer function that associates a plurality of positions along the line or curve with respective elements of the sequence;
detecting an input operation by the user, wherein the input operation selects one of the plurality of positions;
determining the element of the sequence that corresponds to the user-selected position, according to the defined transfer function; and
navigating within the media item to the determined element,wherein the transfer function is a nonlinear one-to-one mapping between the positions along the line or curve and the elements of the sequence.

Abstract
A method and apparatus for user-controlled navigation within a media item comprising a sequence of elements. The method comprises: defining a line or curve for controlling the navigation; defining a transfer function that associates a plurality of positions along the line or curve with respective elements of the sequence; detecting an input operation by the user, wherein the input operation selects one of the plurality of positions; determining the element of the sequence that corresponds to the user-selected position, according to the defined transfer function; and navigating within the media item to the determined element, wherein the transfer function is a nonlinear one-to-one mapping between the positions along the line or curve and the elements of the sequence.

15. A media player apparatus, for playing or displaying a media item comprising a sequence of elements, the apparatus comprising:
-
a display screen, for displaying to a user a graphical interface for controlling navigation within the media item; an input device, for user input; and a processor, for processing the user input in order to control the navigation, wherein the processor is adapted to; define a line or curve on the display screen for controlling the navigation; define a transfer function that associates a plurality of positions along the line or curve with respective elements of the sequence; detect, using the input device, an input operation by the user, wherein the input operation selects one of the plurality of positions; determine the element of the sequence that corresponds to the user-selected position, according to the defined transfer function; and navigate within the media item to the determined element, wherein the transfer function is a nonlinear one-to-one mapping between the positions along the line or curve and the elements of the sequence.
