    Abstract: A digital rights management (DRM) system for distribution of digital content such as audio or video uses a token passing scheme to enhance security of the content from unauthorized access and use, including access by unauthorized players. The token is requested from the central content or DRM server by a host device such as a user's computer, using security related information. The token is then passed to a media player associated with the host device, the token being encrypted using a key special to that particular player. Upon receipt of the token, the player transmits back to the server certain related security information confirming receipt of the token and in return receives keys for decryption of the associated digital content. In the absence of proper passing of the token, player access to the content, or further access to other content, is denied. This also allows the player to communicate directly with the server for obtaining the keys.

    Abstract: Improved approaches for users to with graphical user interfaces of computing devices are disclosed. A rotational user action supplied by a user via a user input device can provide accelerated scrolling. The accelerated nature of the scrolling enables users to scroll or traverse a lengthy data set (e.g., list of items) faster and with greater ease. The amount of acceleration provided can be performed in successive stages, and/or performed based on the speed of the rotational user action. In one embodiment, the rotational user action is transformed into linear action with respect to a graphical user interface. The resulting acceleration effect causes the linear action to be enhanced such that a lengthy data set is able to be rapidly traversed.
