Abstract

The present invention discloses a multimedia device capable of processing a recognized speech-based command. In one embodiment, the device may include a memory to store at least one application therein; an application manager for executing any of the at least one application stored in the memory; and a controller configured to receive from the application manager a list of at least one recognized speech-based command that can be executed by the executed application, wherein the controller is configured: to control a network interface module to transmit any speech-based data received from an outside and the list to the server; and to control the executed application or execute a function non-specific to the currently-executed application, based on a feedback result value received from the server via the network interface module.

First claim

What is claimed is:

1. A multimedia device capable of processing a recognized speech-based command, the device comprising:
a memory to store multiple applications;
an application manager for executing a specific application to be currently-executed among the multiple applications stored in the memory; and
a controller configured to:
receive from the application manager a list of at least one predetermined speech-based command that is predetermined as being escapable of being processed by the specific application, wherein the list changes depending on the specific application being currently-executed;
control a network interface module to transmit both speech-based data received from an outside and the list of the at least one predetermined speech-based command that is predetermined as being capable of being processed by the currently-executed specific application to a server; and
control the currently-executed specific application based on a feedback result value received from the server via the network interface module.

2. The multimedia device of claim 1 , the controller is configured to request the list of the at least one predetermined speech-based command that is predetermined as being capable of being executed by the currently-executed specific application when an application execution triggering condition is satisfied via a shortcut key from a remote controller.

3. The multimedia device of claim 1 , the application manager reports to the controller that a speech recognition service mapped to the currently-executed specific application is available when the specific application is executed.

4. The multimedia device of claim 1 , wherein the controller is configured to output an On Screen Display (OSD) querying whether to control the currently-executed specific application regardless of the feedback result value received from the server via the network interface module.

5. The multimedia device of claim 1 , wherein the multimedia device includes a set top box (STB), a digital television (DTV), and/or a mobile device.

6. A method for controlling a multimedia device capable of processing a recognized speech-based command, the method comprising:
executing a specific application to be currently-executed among multiple applications stored in a memory;
receiving from the application manager in the device a list of at least one predetermined speech-based command that is predetermined as being capable of being processed in the currently-executed specific application, wherein the list changes depending on the specific application being currently-executed;
transmitting both speech-based data received from an outside and the list of the at least one predetermined speech-based command that is predetermined as being capable of being processed by the currently-executed specific application to the server; and
controlling, by a controller, the currently-executed specific application based on a feedback result value received from the server via the network interface module.

7. The method of claim 6 , wherein the method further comprises:
requesting the list of the at least one predetermined speech-based command that is predetermined as being capable of being executed by the currently-executed specific application when an application execution triggering condition is satisfied via a shortcut key from a remote controller.

8. The method of claim 6 , wherein the method further comprises:
reporting, by the application manager, to the controller that a speech recognition service mapped to the currently-executed specific application is available when the specific application is executed.

9. The method of claim 6 , wherein the method further comprises outputting an On Screen Display (OSD) querying whether to control the currently-executed specific application regardless of the feedback result value received from the server via the network interface module.

10. The method of claim 1 , wherein the multimedia device includes a set top box (STB), a digital television (DTV), and/or a mobile device.
