Abstract: A method of playing back audiovisual content together with associated application content, is described, for example using an extended DVD system to play back MHP broadcast content including the inter-active content. The DVD disk includes at least partially an MHP API to enhance the capabilities of a DVD player.

The invention further provides a composition comprising a pharmaceutically suitable carrier and at least one compound of the invention, a method of killing a cancer cell, and a method of treating cancer in a mammal.

Abstract: A copy-protected application is broadcast to terminals (60) in a digital broadcasting system such as the Multimedia Home Platform (MHP). The application comprises a launcher application (310) and a main application (320). The launcher application (310) causes a terminal to create a server, such as an HTTP server (315) on the terminal (60). An application loader, such as a DVBClassLoader (316), loads the main application into the terminal via the server (315). The main application can be an encrypted application which is decrypted as it passes through the server (315). The launcher application (310) obtains authorization from an external party before proceeding with decryption.

Abstract: An extended DVD system includes a DVD player 2 capable of playing disks 6 with extended application capabilities. On inserting a disk, a DVD video virtual machine (VM) 20 is started from a platform-independent execution environment (18), which reads the video content from the disk and provides an audiovisual display based on that content. The DVD video VM 20 determines when specified events occur and calls back to the platform-independent execution environment 18, which causes commands to be executed such as a separate application stored on the DVD disk 6.

Abstract: A digital broadcasting system, such as DVB-MHP, transmits applications (320) in encrypted form to terminals (60). Details about the application, such as encryption method, cost and payment details are transmitted to terminals. Terminals use an interaction channel (85) to obtain authorization to access the application (320) from an authorizing entity (55). Authorized terminals receive a key (215) which can be used to decrypt the encrypted application (320). The functionality to authorize the terminal can reside on the terminal (60) or it can form part of a launcher application (310, FIG. 5) which is received by the terminal.

Abstract: The self-powered electrical generator is composed of components that are of current technology that I have arranged so that this new type of electrical generator does not require a secondary substance, power source, or the forces of nature to function. In addition, the unit is self-sustaining for indefinate periods of time. I have duplexed the components into full functioning sets to prolong the life of the components and to allow for the possibility of maintenance without interruption of service.
