terminal 10 includes a display (display device) in order to display the game result to the player.
This display may be a video display 12, as shown, or a mechanical display. In the case of the
video display 12, for example, a CRT, an LCD, a plasma display, etc. can be used, and besides,
various known video displays can be used. The player performs various operations on the
gaming machine terminal 10 in order to make a bet and make a choice regarding the game. The
game machine terminal 10 is equipped with a button panel 14 with a mechanical push button
switch and a touch screen provided on the screen of the video display 12 so that the player can
operate them. .
[0009]
The operation of the gaming machine terminal 10 will be described in detail below, but here, as
one specific example, the case where the betting game executed by the gaming machine terminal
10 is a video slot machine game will be described. When executing a video slot machine game,
video images representing a plurality of rotating reels 16 and a plurality of pay lines 18 are
displayed on a video display 12. Each pay line 18 corresponds to a straight line connecting one
symbol on each rotating reel 16. First, the outline of the operation will be described. If the player
inputs money to the gaming terminal 10 or bets credits, the central processing unit (CPU) (see
FIG. 2) of the gaming terminal 10 inputs the same. Depending on the amount of money made or
the number of credits bet, several pay lines are activated. As a specific example, for example, the
player selects a number of pay lines to be wagered by pressing the "Select Line" touch key on the
display 12. The player further selects the number of coins or the number of credits to be placed
on the selected pay line by pressing the "Bet per line" wagering key.
[0010]
When the pay line is displayed active, pressing the "spin reel (reel rotation)" touch key on the
display 12 causes the reel 16 to start rotating. However, if you want to play the game with the
maximum wager per line, the player presses the "Max Bet Spin" touch key on the display 12, and
in this case as well, When the touch key is pressed, the reel 16 starts to rotate. Alternatively, the
reel may begin to rotate by operating other mechanisms, such as a lever switch or push button
switch. The CPU of the game machine terminal 10 selects one game result (for example, a game
result in the “basic” game) using a random number generation mechanism. The game result to
be selected corresponds to the combination of the “rotation stop positions” of the plurality of
reels. Furthermore, the CPU stops each of the plurality of reels 16 displayed by the video image
at respective rotation stop positions corresponding to the game result. The rotation stop
positions of the reels 16 are graphically displayed by displaying various symbols on the reels 16
10-05-2019

by video images. Then, this graphic display indicates whether or not the combination of the
rotation stop positions of the plurality of reels corresponds to the game result of the win.
[0011]
The player is to know what the result of the winning game in the base game (ie, the combination
of symbols for which a coin or a credit can be obtained) by referring to the pay table (payout
table). Can. This pay table may be posted on the game console 10, or in response to a command
from the player (e.g., when the player presses the "pay table" touch key) It may be displayed on
the display 12 or both of them may be used in combination. A winning game result is any
combination of symbols on reels 16 along the payline being displayed in any of the various
winning combinations shown in the pay table. Refers to the applicable thing. For example, if
three or more of a plurality of symbols on a pay line being actively displayed become the same
symbol, etc., a winning combination is made, and the payout is increased as the number of
aligned symbols increases. I am also making money. If the symbol displayed when the reel has
stopped rotating is in the winning combination, the player wins the payout corresponding to the
combination of symbols shown on the pay table. You can receive the number of credits
multiplied by the number of credits placed on your pay line. The player can pull up the credits
accumulated so far from the gaming machine by pressing the "pull up" touch key. In addition,
when taking out the winning combination, as one specific example, symbols may be determined
in order (from left to right) from the first reel. As another specific example, the symbols are
determined sequentially from the first reel (from left to right) and the symbols are determined
sequentially from the fifth reel (right to left) , Both may be mixed.
[0012]
In addition, one or some of the game results in the base game can be designated as the effect
start game result. Here, the effect start game result is a game result determined to start a special
effect when the game result occurs. Various game results can be designated as presentation start
game results. For example, a specific symbol may be designated as the presentation start symbol,
and the appearance start game result may be generated when the symbol appears on any of the
reels 16, or a series of reels 16 may be displayed. The appearance start game result may be
generated when a specific combination of symbols appears. Particularly in the latter case, the
appearance that a specific combination of the symbols appears on the active displayed pay line
may be regarded as a condition for considering that the effect start game result has occurred, or
Regardless of whether or not the combination of symbols is displayed on the actively displayed
pay line, it may be regarded that a presentation start game result has occurred, regardless of
10-05-2019

where it appears on the display 12. When the effect start game result is generated, the CPU shifts
from the operation mode for executing the video slot game to the operation mode for providing a
special effect corresponding to the effect start game result.
[0013]

[0023]
Dolby Laboratories, Inc. DOLBY DIGITAL® is a digital surround sound format formerly known as
Dolby AC-3, which is a digital surround sound format, for example, digital in memory 106, such
as a DVD or a laser disc. It is suitable for storing audio data in the data storage portion.
According to DOLBY DIGITAL®, in addition to up to five independent channels capable of
providing acoustic effects across the audio frequency band (eg 20 Hz to 20,000 Hz), low
frequency bands (eg 20 Hz to 120 Hz) A dedicated sixth channel that provides only the sound
effects of) can also be used. The five independent channels are a center channel, a left front
channel, a right front channel, a surround left channel, and a surround right channel. Of these,
the center channel, the left front channel, and the right front channel are generally used to
deliver dialogue, music, and sound effects. The surround left channel and the surround right
channel are for providing surround sound and ambient sound effects. The sixth channel is for
subwoofers, which are commonly used to provide low frequency sound effects to reproduce low
frequency sounds that occur in certain betting games . When the game machine terminal is
manufactured, necessary audio data is stored in the memory 106 in the format of DOLBY
DIGITAL (registered trademark), that is, in the form of compressed and encoded digital data. The
digital data stored in the memory 106 is digital data encoded with information representing a
data stream to be sent over each sound channel. The CPU 102 includes a digital surround sound
decoder that decodes the stored digital data into multiple data streams for transmission over
multiple sound channels.
[0024]
As a surround function extension version of DOLBY DIGITAL (registered trademark), there is a
format named DOLBY DIGITAL EX (registered trademark) or SURROUND EX (registered
trademark). This is the audio data in which the third surround channel (that is, the surround back
channel) is encoded and incorporated in addition to the two surround channels described above,
and can be reproduced at the time of playback. The decoded sound of this channel is made to be
emitted from the rear center speaker located behind the player. At the time of manufacture, the
information of the surround back channel is encoded into the surround left channel and the
surround right channel by using a matrix encoding method, and the information of the surround
back channel is decoded from the surround left channel and the surround right channel at the
time of reproduction. (That is, to reproduce). Because of the matrix encoding scheme, the
surround back channels are not completely independent channels. With the above configuration,
an acoustic effect can be provided behind the player, and therefore, a 360 ° surround sound
with a higher entrapment effect can be achieved.
10-05-2019
10
[0025]
Digital There Systems, Inc. DTS DIGITAL SURROUND® is another digital surround sound format
comparable to the DOLBY DIGITAL® described above. Like DOLBY DIGITAL®, this DTS DIGITAL
SURROUND® also provides low-frequency sound in addition to up to five independent channels
that can provide sound effects across the audio frequency band. A dedicated sixth channel can be
used to provide only the effect. However, since the DTS DIGITAL SURROUND (registered
trademark) has a high data transfer rate as compared with the DOLBY DIGITAL (registered
trademark), the storage capacity of the memory 106 is used more.
[0026]
There is a format named DTS-ES MATRIX (registered trademark) as a surround function extended
version of DTS DIGITAL SURROUND (registered trademark). This is the audio data in which the
third surround channel (that is, the surround back channel) is encoded and incorporated in
addition to the two surround channels described above, and can be reproduced at the time of
playback. The decoded sound of this channel is made to be emitted from the rear center speaker
located behind the player. Also, as another DTS DIGITAL SURROUND (registered trademark)
enhanced version of the surround function, there is a format named DTS-ES DISCRETE 6.1
(registered trademark). This is the surround back channel as a completely independent channel,
so the data stream of the surround back channel is a dedicated data stream of this channel, and it
is the surround left channel or surround right channel. It is completely independent of the data
stream.
[0027]
Dolby Laboratories, Inc. DOLBY PRO-LOGIC® is an analog surround sound format, which at the
time of manufacture encodes four channels of audio information and converts it to a two-channel
stereo analog channel It is The two-channel audio data obtained by encoding is stored in an
analog data storage portion of the memory 106 such as, for example, a HiFi VHS tape. The four
channels are a front center channel, a left front channel, a right front channel, and a mono
surround channel. Of these channels, the front center channel is responsible for "fixing" the
spoken position of the dialogue for advancing the betting game to the position of the image
displayed on the video display 12. The CPU 102 is equipped with an analog surround sound
10-05-2019
11
decoder, and this decoder uses a mixing process from the encoded two-channel audio data stored
in the memory 106 when reproducing sound. Generate a front center channel and a surround
sound channel. In this format, the bandwidth of the surround sound channel is rather narrow, on
the order of 100 Hz to 7000 Hz.
[0028]
Dolby Laboratories, Inc. The company's DOLBY SURROUND® is an analog surround sound
format, which encodes audio information of three channels and converts it into a two-channel
stereo analog channel. The three channels are the left front channel, the right front channel, and
the surround channel. Compared to DOLBY PRO-LOGIC®, this DOLBY SURROUND® omits the
front center channel and reduces the surround channel fidelity.
[0029]
In all of the various embodiments described so far, the CPU 102 incorporated in the game
machine terminal 10 selects audio data and processes the selected audio data to reproduce
sound. It was a thing. On the other hand, another embodiment shown in FIG. 11 is suitable for
the game machine terminal 10 and other plural game machine terminals, such as an Ethernet
(registered trademark) local area network (LAN). It connects with the host computer 112
separately installed with those game machine terminals via the network. In the case of this
embodiment, the game machine terminal 10 selects and reads out audio data and video data
corresponding to the game result of the betting game from the built-in memory 106 from its
own, and selects the selected data. It is also possible to apply processing. Also, the function to
determine the game result may be accepted by the host computer 112, or it may be accepted by
the game machine terminal 10 to determine the game result for each individual game machine
terminal It can also be done. Alternatively, audio content and / or video content may be
transmitted from the host computer 112 to the gaming terminal 10, and the gaming terminal 10
may process (ie decode) the received content. The original content can also be played back by
amplifying it. The transmission of the content may be in the form of streaming data, so that the
gaming terminal 10 can start playing back the content before receiving the entire content file. In
addition, in order to enable communication of streaming data format, the game machine terminal
10 collects data of content to be received, and processes the collected data in the form of an
orderly data stream. It is necessary to be able to supply it to an application that converts it into
an audio signal or an image signal. If the transfer speed of streaming data when the game
machine terminal 10 receives the content is higher than necessary, the data of the content is
saved in the buffer in the game machine terminal 10 Good.

The performance, listening environment and physical placement of the individual surround
sound speakers will vary depending on the configuration of the surround sound speaker system.
For example, in the embodiment shown in FIG. 6, the specific installation position of the surround
sound speaker is, for example, about 7 feet (about 2.1 meters) above the floor surface in the
embodiment shown in FIG. Or, it may be located about 10 feet (about 3.0 meters) away from the
gaming machine terminal 10 that intends to provide surround sound. As another example, the
surround sound speaker is installed at a height of about 8 feet (about 2.4 meters) from the floor
and about 12 feet (about 3.6 meters) away from the gaming terminal 10. There is also something
to do. Thus, although the installation position of the surround sound speaker can be various
positions, depending on the installation position, the ability of the speaker to provide surround
sound may be reduced. Therefore, in order to overcome this problem and provide the player with
an optimal sound experience, the operator can perform sound setting, and this sound setting is
for the game machine terminal 10 to set sound. A series of options are presented, which the
operator can do by selecting the appropriate option. More specifically, the on-screen setup menu
is displayed, and the menu is used to allow the operator to access a series of sound setting
options and to access the current settings of each option. As sound setting options, for example,
the following options may be provided.
[0031]
"Speaker balance adjustment": This adjustment operation balances the levels of the front side
speaker and the surround sound speaker using a test tone generator built in the game machine
terminal. When the operator performs this adjustment operation, the operator sits in the position
where the player using the game machine terminal normally sits, and adjusts the output level of
each speaker. To initiate this adjustment operation, the operator may press the "test" key, which
is an on-screen key. Then, a calibration tone resembling a hiss sound is emitted sequentially from
each of the plurality of speakers included in the speaker system. For example, if the loudspeaker
system consists of five loudspeakers, the calibration tones are emitted in the following order: left
front speaker, front center speaker, right front speaker, right rear speaker, left rear speaker Be
done. The state in which the calibration tone is output is displayed on the video display 12 of the
gaming machine terminal 10. When the calibration tones are fired in sequence, the operator can
select the speaker for which you want to adjust the output level, and press the on-screen keys "+"
or "-" Can adjust the output level of the selected speaker. While making adjustments to the
selected speaker, the calibration tone continues to be emitted from the selected speaker without
10-05-2019

moving to the other speakers.
[0032]
“Surround balance adjustment”: This adjustment operation is an imbalance of the sound
caused by the installation position of the speaker and the listening environment condition by
adjusting the left output level and the right output level of the surround sound speaker. To
compensate.
[0033]
“Surround switch”: This switch is normally on and when the operator turns it off, the output
from the surround sound speakers is turned off and the surround sound signal is directed to the
front side speakers Be able to
[0034]
"Delay time": The operator has a long time difference (ie, delay time) between the emission start
timing of the sound emitted from the front side speaker and the emission start timing of the
effect sound emitted from the surround sound speaker. Can be adjusted.
As this value is increased, the emission of sound effects can be delayed.
The adjustment can be performed, for example, in 1 millisecond steps within an adjustment
range of 0 to 50 milliseconds. The operator adjusts this delay time by pressing the on-screen key
"+" key or "-" key.
[0035]
"Surround sound speaker size": The operator can set the surround sound speaker size to either
"small" or "large". The factory setting is "small". If the surround sound format being used includes
a dedicated channel for low frequency effects, setting this setting to “small” will result in the
bass signal of the surround sound channel (eg 90 Hz) The following signals are directed to a
dedicated channel for that low frequency effect. On the other hand, if this setting is set to "large",
signals (including signals in the low frequency range) over the audio frequency band are output

from the surround sound channel.
[0036]
"Surround speaker installation height": This is the height from the floor of the installation
position of each surround sound speaker. The setup screen displays a number indicating the
height (e.g., a height represented by feet), and the operator selects an appropriate one of the
numbers.
[0037]
"Surround speaker installation distance": This is the distance from the gaming machine terminal
of the installation position of each surround sound speaker. The setup screen displays a number
indicating the distance (e.g., a distance number in feet), and the operator selects an appropriate
one of the numbers. Once the surround speaker installation height and installation distance have
been selected, the CPU 102 automatically adjusts the volume level of the surround sound
channel according to those numbers selected.
[0038]
“Impedance”: The operator can set the impedance of the amplification circuit provided in the
CPU 102 depending on whether the impedance of the speaker is 4Ω or 8Ω.
[0039]
"Master Volume": The operator can control the output levels of all sound channels
simultaneously.
One specific example is that the operator can set the volume to either "mute (off)", "low",
"medium", or "high". Also, another example is that the operator can set the volume to any level
between "mute" and "high".

"Bus control": The operator can adjust the low frequency range frequency response of the front
sound channel. "Bus Expansion Control": When this switch is turned on, the CPU 102 enhances
only the low frequency range frequency response of the front sound channel while maintaining
the overall balance.
[0041]
"Treble control": The operator can adjust the frequency response of the front sound channel in
the treble frequency range. "Tone control disable switch": The operator can disable bus control
and treble control to generate an unmodified signal. When this switch is turned on, the acoustic
input signal bypasses the tone control circuit of the CPU 102 and is not influenced by the tone
control circuit.
[0042]
"Dynamic range": Dynamic range refers to the difference between the maximum level and the
minimum level at the sound level. The operator can set the dynamic range to either "maximum",
"standard" or "minimum". The factory setting is "maximum". This option is valid only when audio
data is stored in memory 106 in digital surround sound format.
[0043]
"Low frequency range effect level": The operator can set the level of the low frequency range
effect in the low frequency range dedicated channel in 1 dB steps within the range of -20 dB to 0
dB. The factory setting is 0 dB. This option is used when audio data is stored in memory 106 in
digital surround sound format and CPU 102 decodes the audio data to generate a low frequency
effect signal. Is only valid.
[0044]
"Sound field": The operator can use a plurality of DSP programs provided for the digital signal
10-05-2019
16
processing (DSP) program to be used when the CPU 102 processes audio data read from the
memory 106. From within, you can choose. These DSP programs create various sound fields by
duplicating digital technology of the actual acoustic environment. Specific examples of the sound
space created by the DSP program include sound fields in cinemas, sports venues, stadiums,
disco shops, rock and concert venues, jazz clubs, churches, and concert halls. . When selecting a
sound field, for example, a sound field may be selected according to the theme of the betting
game executed by the game machine terminal.
[0045]
"Sound scheme (sound system)": The operator can set the sound system to either "the theme
sound system" or "standard sound system". The theme sound system uses sound related to the
theme of the betting game. The standard sound system uses sound irrelevant to the theme of the
betting game.
[0046]
The operator can optimize the sound experience provided to the player by the game machine
terminal 10 by setting the game machine terminal 10 using the above-described series of sound
setting options. Moreover, in addition to the series of sound setting options that can be changed
by the setup menu, the maker who manufactures this game machine terminal variously relates to
the recommended installation position of the game machine terminal 10 and the speaker for
surround sound. Technical parameters may be defined. In addition, if the “orientation” of the
surround sound speaker can be changed, it is preferable to include the recommended angle of
the surround sound speaker in the technical parameters. In addition, these technical parameters
should be specified in the introduction manual of the game console.

While the present invention has been described above in the context of several specific
embodiments, those skilled in the art will readily appreciate from the concepts and scope of the
present invention with respect to those embodiments. Various changes can be made without
departing. For example, the embodiments described above employ true surround sound, which
provides audio signals via surround channels to speakers placed behind or to the side of the
player. The present invention can also be an embodiment employing "virtual" surround sound
10-05-2019
17
(3D-surround sound). Virtual surround sound uses a virtual surround sound algorithm, and
examples of such an algorithm include QSound Labs, Inc. SQ Labs, Inc. and SRS Labs, Inc. Inc.'s
SRS (Sound Retrieval System), etc., and there are other algorithms that can be used. The virtual
surround sound algorithm uses only the left front speaker and the right front speaker to generate
a psychoacoustic sound effect comparable to that of a true surround sound format. The
embodiments described above and embodiments obtained by adding obvious modifications to the
embodiments are all included in the concept and scope of the present invention, and the concept
and scope of the present invention are: It is as having indicated to description of a claim.
