Description

TV with voice mute

The present invention relates to a television having a voice mute function, when the audio mute mode is set when viewing a music broadcast through the television, the audio signal is erased from the audio signal according to the corresponding voice broadcast so that only the accompaniment sound is output. It relates to a television with a voice muting function that can be done.

In general, a television receives a TV broadcast signal transmitted from a broadcast station, and then performs playback processing on the TV broadcast signal to reproduce and output a broadcast program provided from the broadcast station through a CRT or a speaker. It is a device that allows you to watch programs as you like.

On the other hand, when a user watches a music broadcast through the television, the stage screen corresponding to the music broadcast or the singer appearance of the appeared singer is reproduced and output through the CRT, and the voice signal and the accompaniment sound of the singer are displayed through the speaker. It is mixed and output.

However, when the user wants to sing along with the song output on the television, the user's audio signal is not matched with the singer's voice signal because the video is output along with the accompaniment sound, unlike the video music player. Mixing results in a lower level of satisfaction with the user singing along to the song in accompaniment.

Accordingly, the present invention has been made in view of the above circumstances, and when a voice muting mode is set for the broadcasting of a specific song while watching a music broadcast, the audio signal for the song is erased and the accompaniment of the song is performed on the speaker. The object is to provide a television with a voice muting function so that only sound is output.

According to an embodiment of the present invention for realizing the above object,

According to the present invention having the above-described configuration, when a song is output in a music broadcast, if the user sets the voice muting mode, the audio signal is erased from the audio signal corresponding to the song, and only the accompaniment sound is output on the speaker. By performing the semi-period function, the user can practice singing with high satisfaction using the television.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a television with a voice muting function, in which reference numeral 10 denotes a remote control for controlling the television remotely or a control panel installed on the front of the television. As a control signal input unit for controlling a setting state of an operation, the control signal input unit 10 includes a plurality of buttons, for example, a 10-key for direct channel selection, a channel up / down button for channel up / down tuning, and a volume. A volume up / down button for adjustment, a power button for turning on / off the power of the television, and the like. A voice mute button 10a for setting is provided.

Reference numeral 12 is a control unit for controlling the overall operation of the television in response to the control signal input from the control signal input unit 10, in the present invention, the control unit 12 is a voice mute mode by the control signal input unit 10 When is set, the voice muting unit 26 is driven so that only the audio signal is erased from the audio signal of the TV broadcast signal received through the antenna, so that only the audio signal from which the voice signal is erased is output on the speaker 24.

Reference numeral 14 denotes a channel data storage for storing channel data for tuning each channel, and 16 denotes a specific TV broadcast signal received through an antenna based on a preset voltage VT applied from the controller 12. A tuner for receiving a TV broadcast signal of a channel, and 18 is an audio IF module for IF amplifying a TV broadcast signal of a channel tuned by the tuner 16 and detecting only an audio signal from the IF amplified TV broadcast signal.

Further, reference numeral 20 denotes an audio signal processor which performs, for example, voice processing such as voice surround, volume control, and voice multiplexing on the audio signal output from the audio IF module 18 under the control of the controller 12. 22 is an audio amplifier for amplifying the audio signal output from the audio signal processor 20 with a predetermined amplification, and 24 is a speaker for outputting the audio signal output in the amplified state from the audio amplifier 22.

Reference numeral 26 is driven based on the control of the control unit 12 to filter only the audio frequency band 300 to 3,400 [Hz] from the audio signal output from the audio IF module 18 and include it in the audio signal. It is a voice muting unit for canceling the voice signal of the person.

Hereinafter, an operation of a television with a voice muting function according to an embodiment of the present invention will be described in detail with reference to the flowchart shown in FIG. 2.

First, the control unit 12 reads channel data of a channel to be tuned by the channel data storage unit 14 in response to the channel tuning signal input from the control signal input unit 10, and then selects a tuning voltage corresponding to the channel data. (VT) is applied to the tuner 16.

The tuner 16 tunes a specific channel among a plurality of channels received through the antenna based on the corresponding tuning voltage VT to apply the TV broadcast signal of the tuned channel to the audio IF module 18. The module 18 IF amplifies the TV broadcast signal, detects only an audio signal from the IF amplified TV broadcast signal, and applies the corresponding audio signal to the audio signal processor 20.

The audio signal processor 20 performs voice processing such as, for example, voice surround, volume control, and volume multiple, on the audio signal under the control of the controller 12, and then outputs the voice processed voice signal to the audio amplifier 22. The audio amplifier 22 amplifies the corresponding audio signal with a predetermined amplification and then applies the audio signal to the speaker 24 connected to the rear stage. The audio signal is reproduced and output (step 50).

On the other hand, while the control unit 12 performs the playback processing for the TV broadcast in step 50, the audio mute button 10a configured in the control signal input unit 10 is operated so that the control signal according to the control unit 12 If the control signal is not input to the control unit 12 (NO in step 52) as a result of the determination that the input of the voice mute button 10a is operated (NO in step 52). Regeneration process is continuously performed.

On the contrary, when the user operates the voice mute button 10a configured in the control signal input unit 10 to sing along with the broadcasted song while the user is watching a music broadcast, the control signal corresponding thereto is input to the control unit 12. (YES in step 50) The control unit 12 applies a predetermined control signal to the voice muting unit 26 to drive the voice muting unit 26 and outputs from the audio signal processing unit 20. The audio signal is muted (step 54).

Here, the voice muting unit 26 filters only voice frequency bands (300 to 3,400 [Hz]) from the audio signal output from the audio IF module 18, and then erases only the voice signal included in the audio signal. The audio signal in which the audio signal is canceled is applied to the audio amplifier 22 (step 56).

The audio amplifier 22 amplifies the corresponding audio signal applied from the voice muting unit 26 to a predetermined amplification signal and then applies the audio signal to the speaker 24 (step 58). By outputting the corresponding audio signal from which the signal is canceled, the user can sing the song according to the audio signal, that is, the accompaniment sound, thereby improving the satisfaction of the singing practice.

According to a television with a voice muting function according to an embodiment of the present invention, when the user wants to sing a song broadcast in a music broadcast, the voice signal is erased from the audio signal corresponding to the song when the voice muting mode is set. Only the accompaniment sound is output through the speaker so that the television performs the semi-period function, so that the user can perform a satisfactory song practice using the television.
