Abstract

A wireless component is authenticated to an in-home wireless entertainment system server by simultaneously or near-simultaneously holding down buttons on the component and server and transmitting a component ID (or encryption results generated from the key) to the server. The server then indicates “authenticated”, and the component can subsequently access the system using its ID.

Claims

10. A method for authenticating a component in wireless communication with a server to the server, comprising:

depressing an authentication button on the server;

depressing an authentication button on the component to cause the component to transmit a message; and

returning “

authenticated”

at the server in response to receiving the message only if the buttons are depressed simultaneously with each other or within a predetermined time period of each other.

11. The method of claim 10, wherein the server includes at least two authentication elements representing respective levels of authentication.

12. The method of claim 10, comprising transmitting at least one component identification in response to manipulating the authentication button on the component.

13. The method of claim 10, comprising transmitting at least one encryption result generated at least in part using a component identification, the encryption result being transmitted in response to manipulating the authentication button on the component.

14. The method of claim 10, comprising providing visual or audible indication of successful authentication of the component.

15. A logic component, comprising:

means, invokable by manipulating a first authentication element, for receiving an identification message transmitted in response to manipulation of a second authentication element; and

means for returning “

authentication”

only if the elements have been manipulated together or within a predetermined period of each other.

1. A wireless home entertainment system, comprising:

at least one server having at least one manipulable authentication element thereon; and

at least one component in wireless communication with the server and having at least one manipulable authentication element thereon, neither element being a general purpose data entry element, whereby a person can cause the server to regard the component as being authenticated by manipulating the authentication elements.

2. The system of claim 1, wherein the server includes logic for authenticating the component when the elements are manipulated simultaneously with each other.

3. The system of claim 1, wherein the server includes logic for authenticating the component when the elements are manipulated within a predetermined time threshold of each other.

4. The system of claim 1, comprising at least two authentication elements on the server for establishing respective levels of authentication for the component.

5. The system of claim 1, wherein the elements are buttons.

6. The system of claim 1, wherein the component includes logic for transmitting at least one component identification in response to manipulating the authentication element on the component.

7. The system of claim 1, wherein the component includes logic for transmitting at least one encryption result generated at least in part using a component identification, the encryption result being transmitted in response to manipulating the authentication element on the component.

8. The system of claim 1, wherein the server further comprises means for indicating that the component is authenticated.

9. The system of claim 8, wherein the means for indicating generates an audible or visual signal.

16. The logic component of claim 15, comprising a server supporting the first element, a component supporting the second element, and a wireless communication path therebetween.

17. The logic component of claim 16, comprising at least two authentication elements on the server for establishing respective levels of authentication for the component.

18. The logic component of claim 16, wherein the message includes at least one encryption result generated at least in part using a component identification.

19. The logic component of claim 16, wherein the server further comprises means for indicating that the component is authenticated.

20. The logic component of claim 19, wherein the means for indicating generates an audible or visual signal.

16-1. The logic component of claim 15, wherein the elements are buttons.

17-2. The logic component of claim 16, wherein the message includes at least one component identification.
