BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to television receivers, and more particularly, to an automatic sound setting and output device and method according to a television program genre for setting and outputting an appropriate acoustic state in accordance with the genre of a television program being broadcast.

In modern society, television is an indispensable medium for modern people. When you wake up in the morning, you can start the day by turning on the television, and in the evening the whole family gathers to sit and have dinner and watch TV. It's probably not an exaggeration to spend almost a day with TV unless you go out on weekends. In this way, TV provides a lot of information to modern people. TV provides modern information such as news, drama, documentary, sports, and movies.

By the way, the sound output system of the conventional television is uniform. In other words, whether the viewer is watching news, watching a movie, or watching a sports program, the sound output state of the television receiver is output in the same state unless the viewer adjusts using a remote control or the like.

Then, in order to see the configuration of the audio circuit in the conventional television receiver, the overall circuit configuration diagram of a general television receiver will be described.

The tuner 110-2 of the image receiving circuit 110 is generally divided into a circuit for UHF and VHF. The signal received from the antenna 100 is transmitted to the tuner 110-2. The tuner 110-2 includes a resonant circuit (not shown) for selecting a reception channel radio wave and converting the frequency into an intermediate frequency signal. The tuner 110-2 produces an intermediate frequency signal of 45.75 MHz and an audio signal of 41.25 MHz. The local oscillation circuit (not shown) has a frequency f2 of 45.75 MHz higher than the image carrier frequency f1 of the receiving channel. It is generated at and mixes f1 and f2 to become frequency conversion. The receiving tube 160 uses a 45.75 MHz video signal and a 41.25 MHz audio signal as an intermediate frequency signal. The intermediate frequency amplifier 110-4 accurately captures the band characteristics, shapes the type of the television signal sent by the residual sideband method, and amplifies about 70 dB. The signal output from the intermediate frequency amplifier 110-4 is transmitted to the image signal detector 110-6. The synthesized image signal detected by the image signal detected by the image signal detector 110-6 is a luminance signal and a carrier color signal. And a burst signal and a synchronization signal, these signals are separated and the luminance signal is transmitted to the image signal amplifier 110-8, and the carrier color signal and the burst signal are transmitted to the color reproduction unit 110-12. , Synchronous signals are transmitted to the synchronous deflection circuit unit 140, respectively. On the other hand, the voice signal is taken out from the intermediate frequency amplifier 110-4, 4.5 MHz as a voice intermediate frequency signal, amplified by the voice intermediate frequency amplifier 120-2, and the FM detector 120-4 performs FM detection. The signal is amplified by the low frequency amplifier 120-6, and the original audio signal is taken out through the speaker 150.

3 is a block diagram showing an automatic sound setting and output device according to the television program genre according to the present invention.

The automatic sound setting and output apparatus according to the television program genre according to the present invention as shown in FIG. 3 includes a timer 300 having current time information; A storage unit 302, which is divided into n areas for each program genre, and stores a surround operation and a volume size differently in the n areas; A control unit 304 for determining a genre of a currently aired program and outputting information on whether a surround operation is performed on the corresponding area among the n areas stored in the storage unit 302 and the volume size information; A selection unit 306 for selecting a signal output from the control unit 304 when the selection mode by the external signal Cm is the automatic mode and selecting a control signal Cc when the selection mode is the manual mode; A sound adjusting unit (308) for adjusting the size of the volume or whether the surround operation is performed according to the signal applied from the selecting unit (306); An audio circuit 310 for generating an original audio signal by an adjustment signal from the sound adjusting unit 308; And a speaker 312.

The user (viewer) applies the external signal Cm to the selection unit 306 using a key attached to the remote control or the front panel of the television. The selection unit 306 determines whether to select the automatic mode or the manual mode by the external signal Cm. In other words, the user selects the automatic mode if the user wants to be automatically provided with the sound state as needed, and if the user wants to adjust the sound state manually rather than the automatic case, the user selects the manual mode. If the user selects the manual mode, then the selection unit 306 will not select the signal of the control unit 304 but the control signal Cc. When the manual mode is set, the description is the same as in the conventional circuit mechanism. On the other hand, if the user selects the automatic mode, the selection unit 306 selects a signal from the control unit 304 to operate the sound adjusting unit 308, the voice circuit 310, and the speaker 312.

Next, operations of the timer 300, the storage unit 302, and the controller 304 having the features of the present invention will be described in detail.

The timer 300 continuously provides the current time information to the controller 304. The storage unit 302 is divided into n areas for each program genre. The storage unit 302 stores whether or not a surround operation and a volume size are different in the n areas. The genre of television programs that are broadcasted is divided into news, drama, movie, sports, documentary, talk show and so on. According to the program genre as described above, there is a genre in which a surround effect is required and a genre that is not necessary. There are also genres that require a larger volume, and some that don't. For example, the news part needs relatively little surround effect and the volume level should be normal level, while the sports part needs relatively surround effect and the volume should be a little louder. Of course, there may be individual differences, but in general. When the user specifies the information that suits the characteristics of the program just started, the data of the designated area (volume size and surround effect operation) is automatically provided from the moment, even if the user does not manipulate it. In addition, since TV programs are repeated in the same time zone on a daily basis and a weekly basis, data of the currently set area can be stored and used later without any further operation. That is, the controller 304, which receives the current time information through the timer 300, stores the data of the corresponding area set at the current time, and then stores the corresponding time, channel, and storage unit 302 when there is no incoming data later. The information is applied to the selection unit 306 by setting the corresponding area of) as an initial value.

4 is a flowchart illustrating an automatic sound setting and output method according to a television program genre according to the present invention.

First, it is determined whether the area is set (400). In other words, the user determines whether the volume size or the surround effect is newly requested.

If a region is set in the region setting determination step 400, the program genre is displayed on the screen (402-1). The type of genre displayed is determined by the manufacturer.

If the area is not set in the area setting determination step 400, the current time is checked and the data of the previously input area is output (402-2). Outputs data of the area set at the current input time. If there is no data of the area set at the current time inputted previously, the predetermined data may be output.

In the program genre display step 402-1, it is determined which genre is selected from among the genres displayed in step 404. If there is no genre selected in the genre selection step 404, the genre selection step 404 continues. ).

If there is a genre selected in the genre selection determination step 404, the control is performed with data of the selected corresponding region.

If the data adjustment step 406 of the corresponding area is performed, it is determined whether or not the data is stored. If it is determined that the data is not stored in the data storage determination step 408, it is returned to a predetermined initial state (return). Goes.

If it is determined that the data is stored in the data storage determination step 408, the current time and channel are stored (410). That is, the current time and channel are stored and used later.

As described above, the apparatus and method described above may require that the volume and the sound state vary depending on the program being broadcasted. This eliminates the inconvenience that the user has to change every time and the same program timetable repeated every day or every week.
