`
`AUDIO SYSTEM AND ITS CONTENTS
`REPRODUCTION METHOD, AUDIO APPARATUS
`FOR A VEHICLE AND ITS CONTENTS
`REPRODUCTION METHOD, COMPUTER
`PROGRAM PRODUCT AND
`COMPUTER-READABLE STORAGE MEDIUM
`
`FIELD OF THE INVENTION
`
`[0001] The present invention relates to the field of audio
`apparatuses that provide contents such as music in a vehicle
`such as an automobile.
`
`BACKGROUND OF THE INVENTION
`
`In the field of an automobile, a typical example of
`[0002]
`vehicle, an audio apparatus has come into widespread use in
`recent years allowing passengers to enjoy various contents
`such as music in a vehicle.
`
`In such a conventional audio apparatus, a passen-
`[0003]
`ger inserts a portable music storage medium such as a CD
`(compact disk), MD (mini-disk), cassette tape into the audio
`apparatus and enjoys music of his/her choice by replaying/
`outputting it from data stored in the music storage medium.
`
`[0004] However, an audio apparatus using such a music
`storage medium is burdensome because the passenger needs
`to take the storage medium storing music to be replayed in
`the vehicle into the vehicle every time the passenger gets on
`the vehicle.
`
`Patent Laid-Open No.
`Japanese
`the
`[0005] Thus,
`11-30986, etc. proposes a technology for directly receiving
`digitized music data from the outside through an audio
`apparatus using a music distribution service and enjoying
`the music data in the vehicle without using a music record-
`ing medium.
`
`the technology described in the Japanese
`[0006] Here,
`Patent Laid-Open No. 11-30986 will be summarized below.
`
`acquisition system
`data
`[0007] The vehicle music
`described in this Publication consists of an information
`center that distributes music to vehicles and a vehicle
`
`capable of wirelessly communicating with the information
`center (see FIG. 2 of the relevant Publication) and the music
`distribution procedure in such a system configuration is
`explained with reference to FIG. 2 of the relevant Publica-
`tion.
`
`the vehicle sends data about a music
`is,
`[0008] That
`replaying condition in the own vehicle (including informa-
`tion to identify music of a distribution request) to the
`information center.
`
`[0009] Upon reception of the data about the music replay-
`ing condition, the information center determines whether the
`requested music data exists in the information center or not
`and if the music data does not exist, the information center
`acquires the data on the Internet from the outside. Then, the
`information center creates music data with the amount of
`
`the
`data reduced (compressed) based on the data about
`music replaying condition and sends the music data created
`to the vehicle. The vehicle replays the music based on the
`received music data.
`
`[0010] According to the audio apparatus using this music
`distribution service, the passenger can enjoy any music at
`
`any time without the need to prepare any music storage
`medium. This allows the passenger to easily enjoy music of
`his/her choice in the vehicle, providing an effect of allowing
`the passenger to spend his/her time comfortably in the
`vehicle.
`
`[0011] Furthermore, the technology described in the Japa-
`nese Patent Laid-Open No. 10-240207 will be summarized
`below.
`
`[0012] This Publication describes a touch-screen type
`audio-visual replay digital system and a plurality of win-
`dows appearing on a display shows information on audio-
`visual contents that can be replayed.
`
`[0013] The user can select a desired window from among
`a plurality of windows displayed to easily replay the audio-
`visual contents requested to be replayed.
`
`[0014] On the other hand, recently, with the development
`of the Internet, music distribution services indirectly using
`the Internet are provided as described above, which allows
`the user to download digitized contents data such as music
`to an information storage medium such as a memory card
`and enjoy music of his/her choice easily.
`
`[0015] Furthermore, recently, individuals often carry with
`them portable audio apparatuses and these portable audio
`apparatuses are also making it easier to enjoy music using
`music data stored in an information storage medium.
`
`[0016] By the way, people go for a long-distance drive on
`a trip, etc., a plurality of passengers often gets on the vehicle,
`in which case, because preference of music varies from one
`person to another, it is preferred that these passengers be
`able to enjoy music of their respective choices and spend
`their time during the long-distance drive comfortably.
`
`In a vehicle equipped with an audio apparatus
`[0017]
`using a conventional music storage medium, satisfying such
`as demand requires each passenger to record music of
`his/her choice to a music storage medium corresponding to
`the audio apparatus or purchase one and take the music
`storage medium into the vehicle.
`
`[0018] As in the case of the Japanese Patent Laid-Open
`No. 11-30986, the audio apparatus using the music distri-
`bution service provided from the information center can
`freely obtain a variety of music data at any time by a
`required amount. This allows the passengers to freely enjoy
`music of their choice without the need to take the music
`
`storage medium into the vehicle.
`
`[0019] The audio apparatus using the music distribution
`service provides such convenience, but on the other hand,
`because this audio apparatus receives music data from the
`outside by radio (wireless telephone line, etc.), it takes some
`time of communication to download music data of one piece
`of music for example. Therefore, if, for example, electro-
`magnetic interference occurs while the music data is being
`downloaded during a drive, the audio apparatus is unable to
`reliably receive the music data of the relevant piece of
`music.
`
`[0020] And in the case where the music data cannot be
`received reliably, it is necessary to receive the music data
`again. Thus, even the audio apparatus using the music
`distribution service is still not sufficient in respect of user
`friendliness.
`
`17
`
`
`
`US 2001/0028717 A1
`
`Oct. 11, 2001
`
`[0021] Moreover, downloading music data from the music
`distribution service in the current communication environ-
`
`ment entails a high communication cost, and so it is prob-
`lematic in respect of cost, too.
`
`[0022] Therefore, one possible method of enjoying music
`of one’s choice reliably and at low cost without using such
`a music distribution service is to use music data included in
`
`a portable audio apparatus. This is because the portable
`audio apparatus that each passenger carries includes music
`data of his/her choice beforehand and using this music data
`allows the passenger to reliably enjoy music data of his/her
`choice in the vehicle.
`
`[0023] However, the shape and mode of a portable audio
`apparatus varies from one model to another, and the wired
`connection port and the shape of its information storage
`medium also vary. For this reason, using this portable audio
`apparatus in the vehicle requires the passenger to set the
`audio apparatus in a mount pre-installed in the vehicle,
`connect it to an in-car audio apparatus via a cable or insert
`or remove the information storage medium to take the music
`data of portable audio apparatuses of all models into the
`in-car audio apparatus, which is difficult in practice.
`
`[0024] Moreover, even if wired connection ports of por-
`table audio apparatuses of all models and information stor-
`age media are standardized having a common shape and
`mode, there remains a possibility that the passenger will still
`need to set the audio apparatus in the mount and insert or
`remove the information storage media, which is a problem
`of requiring time and trouble.
`
`SUMMARY OF THE INVENTION
`
`[0025] The present invention has been proposed to solve
`the conventional problems, and has as its main object to
`provide, when a plurality of passengers get on an automo-
`bile, for example, an audio system and its contents repro-
`duction method, audio apparatus for a vehicle and its con-
`tents reproduction method, computer program product and
`computer-readable storage medium capable of easily and
`reliably replay contents data in a portable audio apparatus
`carried by passengers inside the vehicle and outputs the
`contents data as sound so that passengers can enjoy music of
`their respective choices in the vehicle without the need to
`download contents data such as music and conversation
`from the Internet.
`
`[0026] To solve the above problems, the present invention
`is constituted as follows.
`
`[0027] That is, the present invention provides an audio
`system that reproduces contents information as sound in a
`vehicle, composed of a portable audio apparatus (200, 200a,
`200b) carried by a passenger of the vehicle and an audio
`apparatus (100) mounted in the vehicle, characterized in that
`the portable audio apparatus includes contents information
`retaining means (204) for retaining contents information and
`transmitting means (205) for transmitting the content infor-
`mation to the audio apparatus at least by means of a radio
`communication, and the audio apparatus includes receiving
`means (110) for receiving the contents information from the
`portable audio apparatus at
`least by means of a radio
`communication, storing means (102) for storing the contents
`information received by the receiving means and controlling
`means (101, 103) for reproducing the contents information
`
`stored in the storing means and outputting the reproduced
`information as sound from speakers(28) mounted in the
`vehicle.
`
`[0028] Another system configuration to attain the same
`object is an audio system that reproduces contents informa-
`tion as sound in a vehicle, composed of a portable audio
