Description

TECHNICAL FIELD [0001] The present invention relates to a thin media card configured to transmit data in a storage memory to a device in contact and non-contact manner, and a device for reproducing data in a media card, and a device}

In the age when music contents were used through media such as records, cassette tapes, CDs and DVDs, two major values of 'collectible value' and 'appreciation' were delivered to users through the media. However, as the time has come to use digital music through the development of IT technology, it has succeeded in adding new value of 'convenience' in addition to conveying the value of 'appreciation'. However, I lost the value of 'collectible value'. As a result, the value of the music itself has been significantly lost, and thus the structure of the music industry has become unreasonable, in which online music service providers lead profits. In the future, it is necessary to provide 'collectible value', 'appreciation', 'convenience' and 'community' through new music media. In other words, with the widespread use of smartphones through MP3s, CD and DVD player functions have begun to be removed in most devices (computers, CD players), especially in car car audio. As a result, traditional CDs and DVDs in the offline market are disappearing. With the recent introduction of various solutions that can make music selection more convenient along with the popularization of online music through smartphone, the existing media market such as CD and DVD is further shrinking. For example, a recording medium on which a method of managing a media content file using an NFC medium, a management server used therein, and a program for executing a method of managing a media content file using the NFC medium, registered as a patent registration No. 10 1683551, Is connected to the NFC reader at the bottom of the smartphone, it is automatically connected to the specified sound source management server, and the specified music is downloaded. On the front of the NFC tag, the image of the purchased sound source was printed so as to feel the intestinal sensitivity and started to be released as "Keno album and card". In other words, it can be evaluated as media using the NFC medium, which can satisfy both the analog sensibility of purchasing the desired album in the offline store and the desire to permanently store the purchased album.

The present invention provides a new media which can replace the disappearing CDs and DVDs by providing "convenience" that can be used in various terminals as well as a smart phone, with more emphasis on the "collection value" .

     The offline music market, which had been in its heyday until the 1990s, was largely eroded by the online music market that appeared with media files such as MP3 files in the 2000s. On the other hand, generations (especially older people) who did not adapt to the MP3 player such as storing the music as a file in this process became out of the music market and the size of the entire music market was reduced. However, due to the illegal copying and illegal transmission of MP3 files, the online music market also faced the limitations of its growth. As a result, the sound source suppliers started an audio streaming service, which is basically an illegal copy and illegal transmission . However, the quality of the service is greatly influenced by the communication environment in the sound streaming service, and a data fee is imposed every time the user executes the corresponding media content. As a result, in the process of reorganizing the downloading sound source market such as MP3 files into the sound source market which is a streaming service center, many sound source consumers have lost their market. Such market deserters still have a desire for consumption of music, but they are not meeting the emotional needs of users in the current music market. In other words, such market-abandoners still have a desire to purchase music at off-line stores or have a desire to keep the purchased sound source forever, The development of new media is urgent.

In 2008, Kookmin Bank of Korea distributed '& d card' with high capacity memory card to credit card, store sound source on thin credit card and listen to music with '& d player' provided. '& DCard' provided 'convenience' rather than CD and DVD, but it could not create 'collectible value' while transmitting only a generalized image of credit card type, and was disappeared as a new memory card. The Kookmin Bank has developed this technology and has provided a credit card and at least two semiconductor chips on a plastic substrate of a standard size according to the patent registration No. 10 0939789. One of the at least two semiconductor chips is a digital compressed file of MP3 or other music And a drive circuit capable of outputting the MP3 or other compressed sound source data, wherein the drive circuit decodes the MP3 or other compressed sound source data to reproduce the sound source data, A D / A converter for converting the decoded and reproduced data into an analog sound; a controller for controlling the memory, the decoder, and the D / A converter; and a memory for storing format information for interfacing with an external terminal, And a second chip (financial IC) And a music storage unit in which a digital compression file of MP3 or other music is downloaded under a condition that a data usage fee such as a digital compression file of MP3 or other music is deleted from the value charging unit, .

Along with the rapid popularization of smartphones, MP3 players and PMPs, which have been popular since the early 2000s, are changing to disappear by losing their competitiveness. In an effort to provide 'the value of music' in a nearby smartphone, it will be possible to manage content files using NFC media and NFC media in 2015, and patents from Korean companies (Keno Co., Ltd.) And released 'Keno Album'. The 'keno album' is a file that allows the management server to transmit a media content file transmission request including a unique code provided by the NFC medium to a user terminal on which the media content file management program is installed, Receiving from a user terminal (smart phone); (b) the management server performing authentication for the media content file transfer request based on the unique code; And (c) transmitting, by the management server, a media content file corresponding to the unique code to the user terminal.

It is an object of the present invention to provide a new medium which enables a user to satisfy both the analog sensibility in which the user directly purchases a desired album and the desire to permanently store the purchased album in the offline store, And to provide a method of managing and utilizing media content files. Recently, "Kino Album and Keno Card" is known as an offline new medium replacing CD and DVD, but the following problems must be solved.

"Keno card" of "Keno album" using NFC medium is an NFC tag that does not store sound source. It reads tag information with NFC reader of device (mainly smart phone) It connects with the sound source download server through the mobile communication network and downloads the approved sound source. On the back and front of the Keno Card, images representing downloadable sound sources are printed, partially contributing to the collection value. Since the sound source is not stored in the 'Keno Card' in the form of an NFC tag, it is necessary to solve the problem that the 'collection value' is reduced to half.

With the NFC reader, the smartphone is the strongest and only one of the personal terminals that use the mobile communication network to communicate with the sound source download server. Although the NFC reader is equipped with the iPhone 7 model, Keno Card can only be used on the smartphone for the Android operating system because the NFC reader can not be used other than 'Apple Pay' due to Apple's closed policy. As smartphones replace old MP3 and PMP, it is necessary for new media to enjoy music through smartphone. However, the problem of data cost for downloading the sound source to the mobile communication network is important. In addition, it is necessary to solve the problem of using new media in various types of peripheral devices such as an MP3 player, a Bluetooth speaker, a docking speaker and a car audio without a mobile communication network.

At this stage where CDs and DVDs are disappearing from the music market, unlike large-capacity USB / SD / MMC memory cards, the new medium is an analog sensibility and digital technology capable of visually symbolizing the stored sound source, Providing convenience, pleasure, and ease of carrying should be provided as a basis for lightweight and compact housing. Currently, large-capacity USB / SD / MMC memory cards need to be solved in the music market because it is necessary to read the memory information from the computer to know the stored sound source.

"Keno Card" has emerged as a new medium to replace CD and DVD. However, "Keno Card" in the form of NFC tag is a method of downloading the corresponding music source through authentication process when "Keno Card" is inserted in the NFC reader of the smartphone (1) music appreciation through a smartphone alone, (2) cost of mobile communication network in downloading, (3) NFC tag that does not store sound sources, and (4) various speaker devices can not be used. However, the most advanced concept of next generation media I am suggesting.

In order to solve the above problems, a thin type pad (for example, similar to a credit card financial IC pad) of about 6 to 10 pins for external input / output in a plastic card (for example, credit card, size 85 x 54 x 0.8 mm or less) (Contact type) media card in which the memory card and the memory means are connected to each other. NAND, OTP, and EEPROM are suitable for the memory system even if there is no power supply. Also, the SPI (Serial Programming Interface) communication method that can supply power and input / output data with 6 ~ 10 pins is suitable. The wired media card can directly decode and output the sound source data stored in the wired media card by making contact with an MP3 player and a speaker provided with a contact-type connector having about 6 to 10 pins.

In this step, a memory (contactless) media card can be proposed which connects the memory to the plastic card with the antenna and the RF chip for external input and output to constitute the local communication means (NFC and BT). (Electromagnetic induction) through an NFC reader (including a wireless charging system), and transmits data stored in the memory to an external device by a short distance communication means. For example, a sound source stored on a medium can be reproduced via a smart phone supporting near field wireless communication (NFC and BT). Since the power supplied from the near field wireless communication reader is wirelessly guided to operate, it is not necessary to incorporate a battery in the medium. The wireless media card can not be connected to an MP3 player and a speaker equipped with a contact connector of about 6 to 10 pins.

It is possible to propose a wired / wireless type media card that consists of a memory card on a plastic card in three steps and a thin pad about 6 to 10 pins for external input and output, have. Receives power wirelessly through an NFC reader (wireless charging system), and transmits data stored in the memory to the external device through short-range wireless communication means. Therefore, it is possible to play the sound source stored on the wired / wireless media card through the smart phone supporting the short-range wireless communication. Since the power supplied by the NFC reader is received wirelessly, there is no need to incorporate a battery in the medium. Unlike the wireless media card, the wired and wireless media card can directly decode and output the sound source data stored in the wired / wireless media card by contacting an MP3 player and a speaker equipped with a contact connector of about 6 to 10 pins have.

Ultimately, it is composed of a memory for storing the sound source in a thin plastic case, a thin pad of about 6 to 10 pins for external input / output, an RF chip for receiving energy wirelessly and an RF chip for inputting / outputting data and an antenna, It is symbolized and printed on the front and back sides of the plastic so as to feel the "collection value". As a result, it is possible to provide universality such as ease of use provided by analog sensibility and digital technology, pleasure, simple and lightweight for easy portability, and use in various terminal devices.

In addition, the present high capacity memory card for storing photographs has a problem in that it is difficult to know the stored photographs when the memory information is read by a computer. The new medium can be used for the user to select and store the photographs, and to print out the photo images suitable for the front and back of the plastic using a card printer.

The present invention relates to a memory device for storing a sound source in a thin plastic case, a thin pad of about 6 to 10 pins for external input and output, an RF chip for receiving energy by radio and inputting and outputting data and an antenna, And it is printed on the front and back of the plastic so as to feel the 'collectible value'. Through this, it is possible to provide universality such as ease of use, pleasure, ease of carrying and lightness and simplicity that are provided by analog sensibility and digital technology, and use in various terminal devices. The smartphone is supplied with energy through the short-range wireless communication network (NFC), and the sound source data stored in the memory can be transmitted to an external device to reproduce music. The wired and wireless media card has a contact connector of about 6 to 10 pins It is possible to directly decode and output the sound source data stored in the media card by contacting the installed MP3 player and the speaker.

 First, since the sound source data is stored in the media card of the present invention, and an image suitable for the sound source is printed on the front and rear sides of the media card, the analog sensibility in which the user directly purchases the desired album in the offline store, And the desire to possess it permanently. You can not resell music data that you used online, but you can resell your own media card in the past like record and cassette tapes.

Second, in the method using the NFC tag, since there is no sound source data in the NFC tag, the authentication code is transmitted to the smartphone and is downloaded from the sound source server through the mobile communication network. However, the media card of the present invention stores sound source data, There is no need to download through a mobile communication network, which is highly valuable and has a communication cost.

Third, the wired / wireless media card of the present invention can be used not only for a terminal supporting near field wireless communication, but also for an MP3 player having a contact connector of about 6 to 10 pins and a sound source data It is possible to directly decode and output the data, thereby widening the utilization range.

Fourth, users who are unfamiliar with the use and settlement of an online music service through a user terminal such as a smart phone and a member joining method can easily use the music source media file through an intuitive method of contacting the user's terminal with the media card of the present invention This will have the effect of expanding the size of the media market, such as the music market.

       Fifth, there is an effect that a high-utilization content providing system capable of selectively outputting a sound source with a setting content desired by a user through a smartphone application and generating a sound source of the user can be additionally implemented.

With the proliferation of smartphones, MP3 players, PMPs, navigation devices, and even digital cameras, which have become popular as past terminals, are gradually disappearing. It is close to display resolution, processor performance and notebook computers, and it is expected to integrate office automation in the future. Therefore, it is likely that new media will be intuitively used in conjunction with smartphones, and a new music card using NFC tags will be born in 2015. To wirelessly connect smartphones and new media cards, NFC communication and Bluetooth (BT) can be considered as the wireless communication methods used in smartphones. Near Field Communication (NFC) uses bidirectional communication using a frequency of 13.56 MHz within a short communication distance of about 10 cm (Type 4 maximum transmission rate of 424 kbps). NFC communication is classified into active mode in which power is supplied by itself and passive communication mode in which self power supply (battery) is not supported. The NFC operation modes include an emulation mode for card / tag non-contact, an RW mode for operation as a reader of a passive NFC tag, and a P2P mode for exchanging mutual data between devices. Like smartphone wireless charging devices, NFC tags use electromagnetic induction of power from the RF field of an NFC reader without a battery. Bluetooth, which is the most common short-range wireless communication means, can transmit 10m at a maximum transmission speed of 24Mbps in the 2.4GHz band and consumes only 1mW of power compared to 15mA of NFC. In order to listen to music at home, a lot of speakers are connected to the smartphone with Bluetooth. The present invention comprises a memory for storing a sound source in a thin plastic case, a terminal of about 6 to 10 pins for external input and output, an RF chip for receiving energy by radio and inputting and outputting data, and an antenna, To provide the analog sensibility to feel the 'collectible value' and the convenience and pleasure provided by the digital technology and the simple and light simple to carry easily. The smartphone is supplied with energy through the short-range wireless communication network (NFC), and the sound data stored in the memory can be transmitted wirelessly (NFC or BT) to play music. The sound source data stored in the streaming media card is directly decoded by contacting the MP3 player and the speaker provided with the connector.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concept of the term appropriately in order to describe its own invention in the best way. The present invention should be construed in accordance with the meaning and concept consistent with the technical idea of the present invention. Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

FIG. 1 is an example in which a contact IC card, a non-contact type RF memory card, a combination card, and a hybrid card are classified according to a method of constructing a financial IC, an RF chip, and an antenna for a near field communication in a credit card. The credit card is 85 x 54 mm in size and 0.8 mm thick. It is equipped with an NFC tag (RFID) for use as a financial IC and a transportation card in the inside, and communicates with the financial IC through ISO7616 protocol. Figure 2 is an image showing the '& d card' and '& d player' installed with a high capacity memory that stores sound sources on a credit card released by Kookmin Bank in 2008. Although the credit card was first loaded with a high capacity memory to store the sound source, it could not be used as a media card because it could not personalize the credit card print image so as to feel the unique value of the sound source. FIG. 3 shows a flow of downloading sound source data by connecting a sound source server and a mobile communication network with an authentication code of an NFC tag in a smartphone using an NFC tag. Although it is highly praised as an attempt to use NFC tag as a music album for the first time, it limits the value of the collection to the limitation that only the authentication code is not stored in the NFC tag itself. In addition, there is a limitation in that it is necessary to contact the NFC reader of the smartphone to access the sound source server through the mobile communication network and download the music, and to listen to music only through the smart phone.
