1. A system comprising:
- a media content provider subsystem providing media content over a closed media network;
a closed media network access device communicatively coupled to said media content provider subsystem by the closed media network, said closed media network access device configured toreceive the media content over the closed media network,provide at least a component of the media content including an audio output signal to an output device for presentation to a user, the output device applying at least one equalization setting to the audio output signal set by the user of the output device,receive audio input including user voice input provided to said closed media network access device directly from the user and broadcast audio provided to said closed media network access device directly from the output device, andutilize the user voice input in at least one of a voice command application and a communication application; and
wherein the at least a component of the media content includes an audio component based on the audio output signal, and the audio input includes at least a portion of the audio component as broadcast by the output device, said closed media network access device being configured to estimate and remove the at least a portion of the audio component as broadcast by the output device from the audio input by filtering the audio input to remove the audio output signal, the filtering accounting for the at least one equalization setting applied to the audio output signal by applying an inverse of the least one equalization setting to the audio input.

Abstract
In one of many possible embodiments, a system includes a media content provider subsystem providing media content over a closed media network and a closed media network access device communicatively coupled to the media content provider subsystem by the closed media network. The closed media network access device is configured to receive the media content over the closed media network, provide at least a component of the media content to an output device for presentation to a user, receive audio input including user voice input provided by the user, and utilize the user voice input in at least one of a voice command application and a communication application.

12. An apparatus comprising:
-
at least one processor configured to process media content; an output driver configured to provide at least a component of the media content including an audio output signal to an output device for presentation to a user, the output device applying at least one equalization setting to the audio output signal set by the user of the output device; an audio input interface configured to receive audio input including user voice input provided to said audio input interface directly from the user and broadcast audio provided to said audio input interface directly from the output device; and at least one of a voice command application and a communication application configured to be executed by said at least one processor, said at least one of said voice command application and said communication application being configured to utilize the user voice input, and wherein the at least one processor is further configured to filter the audio input to remove the audio output signal including at least a portion of the broadcast audio to isolate the user voice input, the filtering accounting for the at least one equalization setting applied to the audio output signal by applying an inverse of the least one equalization setting to the audio input. - View Dependent Claims (13, 14, 15, 16, 17, 18)
