Abstract

PURPOSE: A television receiver with a function of setting up audio mode automatically is provided to search type of sound effect of a current broadcasting, and to set up the most proper audio mode when channel is changed or a user watches a new program, by basing on EPG(electronic program guide) information supplied in the broadcasting. CONSTITUTION: When a user changes channel through a user inputting unit(1), a system controlling unit(9) transmits channel change information to a demultiplexing unit(3) according to input of the user. The demultiplexing unit(3) outputs EPG(electronic program guide) information received after channel is changed to an EPG data processing unit(8). The EPG data processing unit(8) transmits a signal that reception of EPG information of a channel selected currently is completed to the system controlling unit(9). The system controlling unit(9) commands an automatic audio mode setting unit(19) to set up the most proper audio mode to a program of the channel selected currently. The automatic audio mode setting unit(19) requests program information of the current channel to the EPG data processing unit(8). Then, the automatic audio mode setting unit(19) notifies the most proper audio mode to a sound effect processing unit(15) by basing on information received from the EPG data processing unit(8). Therefore, sound effect of audio is set up automatically. The automatic audio mode setting unit(19) also displays current audio mode on screen by outputting title of sound effect of each genre to a displaying unit(6).

Description

Television receiver incorporating a function of automatic setting for audio modes}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a TV, and more particularly, to a TV (TV) for automatically setting and outputting a most suitable audio mode according to the nature of a program using electronic program guide (EPG) information.

Hereinafter, with reference to the accompanying drawings the configuration of a general TV as follows.

1 is a diagram illustrating a general TV, a user input unit 1 for a viewer to control a TV, a tuner 2 for tuning a signal received through an antenna, and a signal tuned by the tuner 2. A demultiplexer (3) for demultiplexing the video / audio signal and an electronic program guide (EPG) data, and a video decoder (4) for decoding the video signal separated from the demultiplexer (3). ), An audio decoder 5 for decoding the audio signal separated by the demultiplexer 3, a display unit 6 for displaying the signal decoded by the video decoder 4, and the audio decoder 5 Speaker 7 for outputting the decoded signal), an EPG data processor 8 for managing electronic program guide (EPG) data separated by the demultiplexer 3, and the user input unit 1 On Correspondingly, the demultiplexer 3 controls the demultiplexer 3 and draws electronic program guide data from the EPG data processor 8 and outputs a control signal corresponding thereto.

Referring to the accompanying drawings, the operation of a general TV configured as described above will be described.

First, when a viewer selects a program provided by a broadcasting station or an external program provider using the user input unit 1, the system controller 9 may be a broadcast program or an external program desired by the viewer according to the signal of the user input unit 1. Outputs control signals for tuning and separating programs provided by the provider.

The tuner 2 tunes a program desired by the viewer from the signal received through the antenna, and outputs the signal to the demultiplexer 3 as a result.

The demultiplexer 3 demultiplexes the program desired by the viewer from the signal tuned by the tuner 2 according to the control signal of the system controller 9 to separate the video / audio signal from the electronic program guide data and output the demultiplexer. do.

The video decoder 4 and the audio decoder 5 output the video signal and the audio signal separated from the demultiplexer 3 to the display unit 6 and the speaker 7, respectively.

The EPG data processor 8 stores electronic program guide data separated by the demultiplexer 3 according to the control signal of the system controller 9.

Thereafter, when the viewer requests the electronic program guide data through the user input unit 1 while viewing the program, the EPG data processing unit 8 outputs the electronic program guide data to the system control unit. Electronic program guide data is displayed after signal processing.

In such a typical TV, the audio output is limited to output only to designated sound effects such as stereo or mono, and the user can manually input the audio even if the TV receiver supports it. It is inconvenient to set the audio mode manually.

Accordingly, the present invention has been made to solve the above problems, and based on the electronic program guide information provided in the broadcast, the most suitable type of audio by finding the type of sound effect of the current broadcast when changing the channel or watching a new program. The purpose is to provide a TV (TV) to automatically set the mode to output.

1 is a view showing the configuration of a typical TV (TV)

2 is a view showing the configuration of a TV (TV) having an automatic audio mode setting function according to the present invention

A feature of the TV according to the present invention for achieving the above object is to demultiplex the signal input from the tuner 2 to separate the video / audio signal and the electronic program guide data, and then display the signal by processing the signals. In the TV, the audio mode automatic setting unit which receives the electronic program guide information transmitted from the system control unit 9, sets the most suitable audio mode by distinguishing the genres of each program, and delivers it to the audio decoder 5 ( 19) and a sound effect processor 15 for processing sound effects for each program genre according to the audio mode set by the automatic audio mode setting unit 19.

Hereinafter, a preferred embodiment of a television (TV) according to the present invention will be described with reference to the accompanying drawings.

2 is a view showing the configuration of a TV (TV) having an automatic audio mode setting function according to the present invention.

This will be described in detail with reference to the accompanying drawings, the operation of the TV (TV) having an automatic audio mode setting function according to the present invention.

First, when the user changes the channel through the user input unit 1, the system control unit 9 sends the channel change information to the demultiplexer 3 in accordance with the user input.

The demultiplexer 3 outputs the electronic program guide information received after the channel change to the EPG data processor 8, and the EPG data processor 8 indicates that the reception of the electronic program guide information of the currently selected channel is completed. 9) to pass on. At this time, the system control unit 9 instructs the audio mode automatic setting unit 19 to set the audio mode most suitable for the program of the currently selected channel.

The audio mode automatic setting unit 19 receives the automatic setting designation signal through the system control unit 9 and requests the EPG data processing unit 8 for program information of the currently selected channel. In addition, the audio mode automatic setting unit 19 notifies the sound effect processing unit 15 of the most suitable audio mode based on the information received from the EPG data processing unit 8 to automatically set the sound effect of the audio and set The name of the sound effect for each gen is output to the display unit 6 to display the current audio mode on the screen.

The sound effect processor 15 is connected to the audio decoder 5 to classify the program by genre, and then output a sound field to the speaker 7 through the audio decoder 5. It can be implemented as a method of adding a sound effect processing function (sound field processing function per genre) to the existing audio decoder.

In the sound effect processing for each program genre of the present invention, the genre means "Rock", "Classic", "Pop", "Movie", etc. in addition to the existing mono or stereo.

As described above, the TV having the automatic audio mode setting function according to the present invention automatically changes to an appropriate audio mode according to the genre of the program without the user having to change the audio mode for each program. Has the effect of providing.
