Description

Audio mode automatic selection device and method

The present invention relates to a method and method for automatically selecting an audio mode. In particular, an audio effect sound suitable for program content is determined by determining a program ID (identification) of a Korean Broadcasting Program System (KBPS). It relates to an apparatus and a method for outputting. 1 is a block diagram showing the configuration of a conventional audio mode automatic selection device. As shown in FIG. 1, the broadcast signal received from the antenna 200 is tuned to a desired broadcast channel via the tuner 210, and the audio unit 220 detects only an audio signal of the broadcast signal. The audio signal generated by the audio unit 220 is selected to generate various audio effect sounds by the sound effect generator 230 according to a user's selection. When the user applies the audio effect selection signal to the sound effect generator 230 by using a remote control or a key operation, an audio signal to which audio effects such as sports, entertainment, drama, news, and movies are added is output. Therefore, in the prior art, in order to generate an audio effect sound according to each broadcast content, the user directly grasps the broadcast content and operates it by using a remote controller and a key, which is inconvenient in use.

An object of the present invention is to provide a device and method for automatically changing the audio effect sound according to the broadcast content by determining the program ID of the Korean-type reservation recording system (KBPS) received from the broadcast and outputting the audio effect sound corresponding thereto. There is.

In order to achieve the above technical problem, the present invention provides a tuner unit for tuning a broadcast of a desired channel among broadcast signals received from an antenna, an audio unit for extracting an audio signal from a broadcast signal output from the tuner unit, and outputted from the tuner unit. A unique number extracting unit for extracting the unique number of each program by receiving the immediately-K data from the broadcast signal, a control unit for generating a control signal corresponding to the unique number of the program generated in the immediately-K data extracting unit, in the control unit And an effect sound generator for selectively outputting an effect sound of the audio output from the audio unit according to a control signal corresponding to a unique number of an applied program.

In order to achieve the above technical problem, the present invention provides an audio mode automatic selection method for automatically selecting an effect sound of an audio broadcast signal, comprising: extracting bar data from a broadcast signal; A unique number extracting step of extracting a program unique number in a data extracting step, and a sound effect output step of selectively outputting an effect sound corresponding to the contents of the program by determining whether the unique number is a predetermined program in the unique number extracting step; Automatic audio mode selection method characterized in that.

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

In general, the Baro-K system is a Korean-style reservation recording system, which enables viewers to easily and accurately record a program as well as to use the Baro-K service to record a program more easily and accurately than the G-coded reservation recording currently used. You can easily retrieve a week's worth of program information on your TV without using it. Conventional televisions or VCRs incorporating such bar-K functions automatically store broadcast information in memory by channel tuning.

2 is a diagram illustrating a packet 3 format of bar-K data.

The format (packet 3) of FIG. 2 includes information about a program sequence per day (PC), information about a day of the week (PW), information about a maximum program (P_MAX), a unique number (Program ID) for program contents, and the like. consist of.

3 is a block diagram showing the configuration of an audio mode automatic selection apparatus in KBPS according to the present invention, the block diagram of Figure 3 is a tuner 310, tuner 310 for tuning a desired broadcast signal from the antenna 300 The audio unit 360 extracts an audio signal from the broadcast signal output from the broadcaster, the Baro-K data extractor 330 and the baro-K data extracting Baro-K data from the broadcast signal output from the tuner 310. KBPS unit 390 having an ID extraction unit 340 for extracting a program ID from the extraction unit 330, a control unit for generating a control signal corresponding to the unique number of the program generated in the ID extraction unit 340 ( 350, an effect unit generator 380 for outputting audio by adding an effect sound to the audio sound output from the audio unit 360 according to a control signal applied from the controller 350.

As shown in FIG. 3, the broadcast signal is received by the antenna 300 in a high frequency form. The broadcast signal received by the antenna 300 is tuned to the broadcast signal of the desired channel in the tuner 310. The broadcast signal output from the tuner 310 is divided into a video signal and an audio signal, and the bar-K data such as the format shown in FIG. 1 is included in the video signal. The audio unit 360 detects only the audio signal in the broadcast signal, and the bar-K data extractor 330 extracts the bar-K data included in the video signal and stores it in a memory (not shown). 340 extracts a program ID which is a program unique number from the bar-K data extracted from the memory of the bar-K data extractor 330. The control unit 350 is a control signal corresponding to the program ID generated by the ID extraction unit 340, for example, a first control signal if the program ID is an entertainment program, a second control signal if the program ID is a sports program, and the program ID is news. The program generates a third control signal. The sound effect generator 380 adds the sound effect to the audio sound output from the audio unit 360 according to the control signal applied from the controller 350, that is, the first, second, and third control signals. That is, the controller 350 controls the sound effect unit 380 to output a stereo effect sound if the ID of the sports program and a surround effect sound if the ID of the movie program is generated, for example, in order to generate an audio effect sound corresponding to the received broadcast content. .

4 is a flowchart illustrating a method of automatically selecting an audio mode in KBPS according to the present invention, including a broadcast reception process 400, a Bar-K data extraction process 410, a program ID extraction process of the Bar-K data 420, A first determination process 430 of determining whether a program ID is an entertainment program, a process of outputting a first sound effect sound if the program ID is an entertainment program 440, and a second determination process 450 of determining whether a program ID is a sports program. If the program ID is a sports program, the process of outputting a second sound effect (460), the third judgment process of determining whether the program ID is a news program (470), if the program ID is a news program process of outputting a third sound effect (480) )

As shown in FIG. 4, when the television broadcast is first received from the antenna through the tuner (step 400), the KBPS unit 390 extracts the bar-K data during the TV broadcast (step 410), and the extracted bar-K data. The program ID is extracted from the process (420). The control unit 350 determines whether the program ID of Baro-K output from the KBPS unit 390 is, for example, the ID of the entertainment program (step 430). Outputting the sound effect (step 440), determining whether the program ID is the sport program ID (step 450), and outputting the second sound effect if the ID of the sport program (step 460), and checking whether the program ID is the news program. If it is determined (step 470), the third program outputs a sound effect if it is a news program (step 480).

According to the above-described and the present invention, there is an advantage that the sound effect mode suitable for the broadcast content can be automatically changed in the video tape recorder (VTR) or the television receiver.
