Abstract

An apparatus having a memory and an operating system running a plurality of applications that are controlled by user signals, means to register the user signals required by each application, means to receive user signals, and means to send each received user signal to the application registered to require that signal. A method of passing user signals to a plurality of applications running with an operating system comprising receiving from each application information on user signals required by that application; saving in a memory the required user signals associated with each application; receiving a user signal from a user interface device; retrieving from the memory applications that require the received user signal; and sending the received user signal to each of the retrieved applications.

Claims

1. A method for passing user signals in an apparatus having a multi-tasking operating system, the method comprising the steps of:

receiving, via a key manager, a user signal from a user interface device;

identifying, via the key manager, a first application that requires the received user signal;

sending the received user signal from the key manager to the first application bypassing the operating system and thereby enabling the first application to perform a first user function;

after sending the received user signal from the key manager to the first application, translating, via the key manager, the received user signal to a second signal recognizable by the operating system; and

sending the second signal from the key manager to the operating system for sending to a second application running under the operating system and thereby enabling the second application to perform a second user function.

2. The method of claim 1 wherein the first and second applications comprise a user interface and a browser.

3. The method of claim 1 wherein the user signals are received by IR from a remote control device, from front panel buttons, and/or from the system.

4. The method of claim 1, further including error checking and conversion of user signals.

5. The method of claim 1 comprising registering the key manager with an infrared driver and a front panel assembly driver, registering applications that are active and unregistering applications that are inactive with the key manager, registering a set of user signals corresponding to each active application and unregistering the set of user signals upon an active application becoming inactive, and sending received user signals to an active application for which the received user signals are registered.

6. The method of claim 5 wherein upon registration of an application, a name and size for a message queue corresponding to the application is stored by the key manager, upon which the key manager creates one end of the message queue for passing user signals to the application.

7. The method of claim 5 wherein the second application running under the operating system is a top level application, and if the top level application does not want the second signal, the operating system sends the second signal sequentially to a next highest level of application running under the operating system, which accepts the second signal.

8. The method of claim 5 wherein upon registration of an application with the key manager, the type of user signals required by the application is registered.

9. The method of claim 8 wherein the type of user signals is selected from the group consisting of remote control keys, keyboard keys, and front panel assembly keys.

10. An apparatus, comprising:

an operating system;

a key manager operative to receive a user signal and send said received user signal to a first application that requires said received user signal bypassing the operating system and thereby enabling said first application to perform a first user function; and

wherein after sending said received user signal to said first application, said key manager translates said received user signal to a second signal recognizable by the operating system and sends said second signal to said operating system for sending to a second application running under said operating system and thereby enables said second application to perform a second user function.

11. The apparatus of claim 10 comprising a television, a browser, a display, and a keyboard.

12. The apparatus of claim 10 comprising means for displaying a user interface, means for receiving infrared remote control signals, means for receiving front panel assembly signals, and means for receiving keyboard signals.
