Abstract

A transmission system includes at least one receiver 60 and a transmitter 10, 20, 30 for transmitting a title to the receiver. The transmitter also transmits interactive features that enable a user to interact with the title. Thee features interact with the title through a DVD virtual machine. The receiver 60 receives the transmitted title and transmitted interactive features. A controller 250 of the receiver 60 implements the DVD virtual machine to enable execution of the received features in the receiver.

Claims

1. A transmission system including at least one receiver and a transmitter for transmitting a title to the receiver and for transmitting interactive features that enable a user to interact with the title;

the features being operative to interact with the title through a storage-medium compliant virtual machine;

the receiver being operative to receive the transmitted title and transmitted features; and

including a controller for, under control of a virtual machine program, providing the storage-medium compliant virtual machine to enable execution of the received features.

2. A system as claimed in claim 1, wherein the virtual machine program is pre-loaded in a memory of the receiver.

3. A system as claimed in claim 1, wherein the transmitting system is operative to transmit the virtual machine program to the receiver;

the receiver being operative to receive the virtual machine program.

4. A system as claimed in claim 1, wherein the receiver is operative to download the virtual machine program from a download server through a network.

5. A system as claimed in claim 1, wherein the controller is operative to execute application programs for a predetermined receiver virtual machine;

the receiver virtual machine being distinct from the storage-medium compliant virtual machine;

the virtual machine program being compliant with the receiver virtual machine.

6. A system as claimed in claim 1, wherein the receiver is operative to store the received title and features in a storage for subsequent rendering.

7. A system as claimed in claim 1, wherein the receiver is operative to store the received virtual machine program in a storage for subsequent execution by the controller.

8. A system as claimed in claim 1, wherein the title includes a first part for real-time rendering by the receiver and a second part with interactive content accessible through the interactive features.

9. A system as claimed in claim 8, wherein the transmitting system is operative to broadcast the title, where the first and second part of the title are broadcast as separate streams in a same multiplexed stream;

the receiver being a broadcast receiver operative to receive multiplexed streams.

10. A system as claimed in claim 8, wherein the transmitting system is operative to broadcast the first part of the title;

the receiver being a broadcast receiver operative to receive the broadcast first part of a title and to download the second part of the title from a download server.

11. A system as claimed in claim 1 wherein the storage-medium compliant virtual machine is a DVD virtual machine.

12. A receiver for use in the system as claimed in claim 1;

the receiver being operative to receive a transmitted title and transmitted interactive features that enable a user to interact with the title;

the features being operative to interact with the title through a storage-medium compliant virtual machine;

the receiver including a controller for, under control of a virtual machine program, providing the storage-medium compliant virtual machine to enable execution of the received features.

13. A virtual machine program product for causing a controller in a receiver for use in a system as claimed in claim 1, to provide a storage-medium compliant virtual machine to enable execution of the received interactive features that enable a user to interact with a received title;

the interactive features being operative to interact with the title through the storage-medium compliant virtual machine.
