Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game apparatus using multi-channel data using DVD audio or the like.

[0002]

2. Description of the Related Art Conventionally, audio signals of front two channels, center one channel, and rear (rear) two channels of a movie or the like are reproduced by respective speakers to enjoy a sound field full of surround effects. In. Also, in a car racing game or the like, the front two channels and the rear two channels are used to create a sound field as if actually racing at a race track. Recently, a DVD audio standard has been proposed which aims at higher sound quality by higher sampling than a normal compact disc. According to this standard proposal, up to 6
The feature is that the audio signal of the channel can be recorded with a high sound quality of a maximum of 24 bits. And in the audio industry, taking advantage of these characteristics,
Making a more realistic sound field is expected. Accordingly, the present invention has been made to meet the above-mentioned expectation, and an object of the present invention is to provide a game apparatus for multi-channel reproduction using high-quality sound such as DVD audio.

[0003]

According to the present invention, there is provided a game apparatus comprising:
In order to solve the above-mentioned problems, the invention comprises the following means. That is,

[0004] At least multi-channel audio data is supplied, and reproduction means is provided for generating the audio data in a predetermined signal form corresponding to each channel. Is supplied to a plurality of speakers arranged at a predetermined interval so as to correspond to each of the channels and to enable identification of a sound image position to be emitted, thereby reproducing a multi-channel audio signal. A game device using multi-channel audio data, comprising: channel data detection means for detecting the presence or absence of data corresponding to each channel of the multi-channel audio data sequentially supplied; and a game device for temporarily storing the data. Data storage means and the data stored in the data storage means. Data and game apparatus using the multi-channel audio data, characterized in that the which is configured by providing a means for determining the presence or absence of coincidence by comparing the data supplied in response to an operation input of the user.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to preferred embodiments. FIG. 1 is a schematic configuration diagram of a game device according to one embodiment of the present invention, and FIG. 2 is a flowchart showing processing of the game device. In these figures, reference numeral 1 denotes, for example, moving image and still image data packed in a predetermined data sequence and high-sampled 24-bit-equivalent 5-channel audio data (each data as shown in FIG. 3 described later). This is a DVD audio disk (hereinafter simply referred to as a disk) in which sound source data corresponding to channels are packed and recorded in a predetermined format. The five channels of audio data are, for example, signals of a front left channel (Lf), a front right channel (Rf), a front center channel (C), a rear left channel (Ls), and a rear right channel (Rs). The video and audio data (step S1) recorded on the disc 1 are read by a drive device 2 including a reproducing means such as a pickup, and then read by a video decoding unit 3a and an audio decoding unit 3c in the reproducing device 3. The decoded video data is converted by a digital / analog converter (D / A) 3 b and supplied to the display 14.

On the other hand, the audio data separated into five channel signals by the audio decoding unit 3c are converted into PCM signals by a PCM conversion unit 3d, and similarly converted into analog signals by a D / A converter 3e. The converted speakers SP1, SP
2, SP3, SP4, and SP5 for reproduction (step S2).

The audio signal converted into the PCM signal is also supplied to a channel and rhythm information detecting section 7 for detecting the position information of a sound source (one note), that is, channel information and rhythm information (S3). . For example,
Here, the presentation sound is a sound source position and a rhythm as shown in FIG. 3, and the audio signal is a sampling frequency of 48 kHz.
Consider the case of a PCM signal of z.

The data of each channel is arranged every 1/48000 seconds as shown in FIG. Therefore, the channel and rhythm information detection unit 7 determines the sound source position and the rhythm based on whether or not there is a sound at that time.
A simple data structure as shown in (b), that is, at time t, data "1" if there is a sound in each channel, and data "0" if there is no sound, and the channel and rhythm information are reworked. Is output. The output channel and rhythm information are temporarily stored in the data storage unit 8a (S4).

Here, an operator M (hereinafter, simply referred to as a respondent) who plays the game has speakers SP1, SP2, SP
Stand at the center that is equidistant from 3, SP4 and SP5. The respondent responds to the answer pad (input device) 9 about the direction in which the sound is heard and the rhythm of the sound (S5). As shown in FIG. 5, five buttons on the answer pad 9 are prepared for each speaker. Here, since there are five channels, there are five buttons, but they may be provided according to the increase or decrease of the channels.

After the rhythm sound shown in FIG. 3 is reproduced from each speaker, the respondent presses a button corresponding to the speaker that can be heard from the sound source position as heard (S5). The channel and rhythm information detection unit 7 converts which button was pressed at which time into the data shown in FIG.
6) Output to the data storage unit 8b as answer data, and the data is stored (S7).

Next, a data storage unit 8a and a data storage unit 8b
Are compared by the pass / fail determination unit 10 (S8). If they are exactly the same, the answer is “correct”. However, for example, in the rhythm determination, the game control unit 12 can change the setting such that a few milliseconds before and after the time when the sound of the correct answer data is within the correct answer range.
In addition, since the respondent may answer the whole rhythm a little earlier or later, the pass / fail judgment unit 10 may appropriately compress / expand the time to judge the pass / fail.

When the answer is correct, the sound source of "Fanfare" and the video such as "OK" which have been selected in advance by the control unit 12 for the correct answer are loaded from the respective data collections and presented to the respondent. (S9, S1
0). Similarly, when a mistake is made, a video such as "buzzer sound" or "NG" is presented (S11). Then, the next video and audio signals are presented.

As described above, the number of channels may be increased each time the number of correct answers increases, or a complicated rhythm may be presented. If the answer is correct, the score may be increased, a message corresponding to the score may be displayed, or the game end music may be changed according to the stage.

[0014]

As described above, according to the game apparatus of the present invention, for example, a multi-channel audio data conforming to the DVD audio standard or high-quality audio data is used to enjoy a sound field full of surround effects and the like. You can enjoy the game while developing the rhythm.
