DETAILED DESCRIPTION OF THE INVENTION

According to the present invention, when a separate content using device is connected to a computer, it is recognized as a CD-ROM and automatically executed so that the driving program is automatically executed. When an external storage medium is connected to a computer, a USB medium or a card storage medium other than a CD medium is recognized by the computer, but a program installed in the medium is not automatically executed. However, in the present invention, when an external content using device such as a CD medium is connected to a computer, an embedded program is automatically executed so that a user can more easily execute download or other authentication.

In addition, the present invention uses an automatic authentication method to facilitate the verification of the authentication key or serial for authentication to the content using device.

As a content using device according to the present invention, a computer is used in a general manner of operating contents in a computer, but an operating program operates so that only contents to be described later will be used. Hereinafter, a description will be given focusing on an independent external content using device.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 also illustrates an example in which the content using device of the present invention can be recognized as a CD ROM.

As a method of recognizing a CD when a content using device according to the present invention is connected to a USB or another port in connection with a computer, a description will be given based on a representative interface device USB.

As a general computer, a host computer may be classified into an operating system and a USB interface in order to be connected to a content using device in accordance with the present invention.

The content using device includes a nonvolatile storage device, an operation processing part, and an interface unit for connecting with a computer. In general, a CPU can be used for the operation processing part, and the interface unit is described as a USB interface because the USB interface is easy to use.

As shown in FIG. 1, the nonvolatile storage device is divided into two zones and includes a descriptor table in duplicate. First, a zone contains a descriptor table for recognizing a USB CD-ROM so that the content-using device can recognize it as a CD-ROM on a computer and contains data space for the USB CD-ROM. The data space may store an autorun program, a device driver, a manual, etc. like a normal CD. In other areas, it is a space for storing data, such as a general USB memory stick or other general memory, so that a descriptor table for recognition as a general USB storage device is recognized as a storage device like a general memory stick, and a data space for a general USB storage device. In this case, various contents may be stored in the data space.

When a device using a content is connected to a USB port of a computer (depending on the characteristics of the device used, a separate power supply may be required), the computer can provide information (device descriptor) such as the type, classification, transmission method, and transmission speed of the mobile device. Require. At this time, it is recognized as a general random access memory, a CD-ROM, a hard disk, etc. according to the information returned from the content using device (USB device).

Accordingly, the content using device has a descriptor table for transmitting the response information differently according to a user's request, function, and state, and recognized as a different kind of device as described above. For efficient management and use of data, non-volatile storage is divided into areas used when recognizing USB CD-ROM and areas used when recognizing as general removable disk.

Hereinafter, referring to FIG. 1, a process of connecting the content using device to a computer through a USB port and recognizing the device by the computer will be described in detail. FIG.

1) First, the user connects the power to the device and the computer through the USB port. In this case, if the power supply is not required depending on the content using device, the connection is terminated by connecting as a general USB memory. In this case, the case where the connection is only performed is a case where the separate storage of content, that is, the latter general memory storage space described above is not necessary.

2) The operating system (OS) of the computer detects the change and connection of the USB interface and sends a USB SETUP packet containing a value that requires a device descriptor (a collection of information for recognition to the host computer) to recognize the device. Transmit to this unit via bus.

3) The content using device transmits the device descriptor required by the received SETUP packet to the computer. At this time, the computer determines the type and characteristics of the device based on the device descriptor so that the computer responds with information read from the descriptor table stored according to the user's request, function, and status. For example, the auto start program should be activated at the first boot (connection) of the unit, so the descriptor table for recognition as a USB CD-ROM is selected to be recognized as a USB CD-ROM to use the CD-ROM autorun function. For the function of downloading contents (including transmission from a computer) and adding and deleting contents by a device user, a descriptor table for recognition as a general USB storage device is selected.

4) The computer receives the descriptor and then assigns a new address for this device. At the same time, the assigned address is transmitted to the unit.

5) This device saves the new address in the USB device address register so that the device can be recognized by that address.

6) The computer asks for the remaining descriptors needed for recognition, and responds with information using different descriptor tables depending on the recognition type of the device.

7) When the computer receives all the descriptors, the recognition process to the USB removable storage device is completed.

Hereinafter, referring to FIG. 2, the steps up to connection with a computer and execution of a content download program will be described in relation to the execution of the content using device of the present invention as described above.

1) Turn on the device using the content.

2) The device is initially recognized by the computer as a USB CD-ROM drive. In order to be recognized and used as a CD-ROM, the data of the electronic device described above includes a basic 'startup program' required to start 'content download' and 'device management' and a driver or manual necessary for the device. The above data cannot be deleted by user because it is connected and recognized by CD-ROM method. It prevents user's mistakes or random deletion of the basic things necessary for connection and operation of the device with the computer, and can be used easily without downloading a separate driver or installing through a separate CD-ROM disk. In order to recognize a CD-ROM disc on a computer, it is preferable that the data area is divided and stored in a format such as ISO 9660 Joliet.

3) The computer's CD-ROM autorun function automatically launches the startup program built into the device. The auto-run feature allows the device to easily access the 'content download and management' program by simply plugging in a USB cable to the computer and turning it on. When the autorun function is started, the computer connects the device to the server and operates the 'content download and management' program using both the data stored in the memory of the device and the data of the call server.

4) Through the 'Startup Program', users can use 'Removable Disk' to store and delete mp3s, videos, photos, etc., like existing portable mp3 players and USB memory devices. Will be selected.

5) If you choose to use it as a 'removable disk', this unit, which is currently recognized as a CD-ROM, will be recognized as a regular removable disk after rebooting, allowing you to easily delete and delete various data such as MP3, video, document files, etc. Make sure

6) If you select 'Device Management and Downloading Content', after rebooting this unit, which is currently recognized as a CD-ROM, it should be recognized as a normal removable disk.

7) 'Start program', which was executed by the autorun function, first checks the device for updates. First, get information and status of F / W and O / S of the device currently connected to the computer. The members of F / W and O / S are each modularized by function and purpose and are located in the internal area which is inaccessible to the user.The information and status are CRC (cyclic redundancy checking), data size, version information, etc. To get it. Next, the latest F / W and O / S information (CRC, data size, version information, etc.) is obtained from the server. The entire data is compared with each other using the CRC, so the speed can be increased. In addition, it is characterized by enhancing the integrity of data through the cyclic redundancy characteristic of CRC, in which a large value difference occurs even with a difference of 1 bit of raw data.

8) A module (need to update) whose information and status of the current device is different from the latest obtained from the server is determined and distinguished using the CRC, data size, version information, etc. described above.

9) Update each module. It is updated in units of modules without updating the entire F / W and O / S. It is characterized by improving efficiency by preventing unnecessary data transmission and updating.

10) After checking the update of the device, in order to check whether the latest 'content download and management program' is installed in a short time, first obtain the CRC value of 'content download and management program' from the server.

11) Check whether the 'content download and management program' has not been downloaded to the current computer or the CRC value obtained from the server and the CRC value of the 'content download and management program' downloaded to the current computer are wrong.

12) If the value is wrong, download 'content download and management program' from server. Once downloaded, the computer does not download again unless the server program is updated, so the latest program can be executed quickly.

13) Run 'Content Download and Management Program'.

Hereinafter, with reference to the detailed picture will be described for the authentication and download of the content using the device while the content using device is connected to the computer as described above. If the server is directly connected to the server through wired or wireless internet or telephone network without going through the computer, the process on the computer is omitted and the device can be substituted.

[Figure 1]

1) When the content using device is connected to the computer and the program is automatically executed as above and the user selects to receive the predetermined content, the computer generates a 'command code' to request to the server. The command code is a combination of content types, names, paths, and server download methods, and is a unique code for identifying content requested by a user. For example, the type of content could be karaoke songs or MP3s, movies, background photos, educational texts, games or other software files, and audio material. The path and name of the content is the unique file name of the content itself stored on the server. The content download method may be selected by using FTP, HTTP, Proxy or the like.

[Figure 2]

2) The computer requests the 'Random Key' from the server and gets the value. The server generates a 'Random Key' and sends it to the computer. At the same time, the server remembers the value. 'Random Key' is a random code generated randomly on the server side. A unique random code of 128 bits or more is preferable, and is generated by using a value that can be different according to the time or environment of the server. Each time a user requests a content, a different algorithm is generated according to a different 'Random Key' to enable secure authentication.

[Figure 3]

3) The computer sends the 'command code' and 'Random Key' from the server to the device.

[Figure 4]

4) The device encrypts the transmitted 'command code' and the 'serial number' generated from the factory by using the 'random key' and adds its own CRC to the computer for the integrity of the encrypted value. Data loss or hacking on the computer side can be protected by checking and comparing the CRC added from the device with the CRC on the server side.

[Figure 5]

5) The computer transmits the encrypted data obtained from the device to the server.

[Figure 6]

6) The server obtains 'command code' and 'serial number' information by decrypting the integrity key using CRC of encrypted data transmitted from the computer and using the stored 'Random Key'. Discard the expired 'Random Key' which was then saved. If the integrity check fails, you can request a retransmission to the computer.If the integrity check is successful but the data cannot be decrypted using the 'Random Key', the decrypted 'serial number' is incorrect. It is determined that reprocessing is suspected so that the user can take measures such as downloading prohibition.

[Figure 7]

7) The server checks the purchase information such as the decrypted 'command code', the download point corresponding to the 'serial number', and the suitability of the content download. Download points corresponding to each of the 'serial numbers' are stored in the server, and access rights and 'download points' corresponding to the 'serial numbers' are given to the contents. The suitability of the download is determined based on a calculated value through a sum or difference between the 'serial number' and the 'download point' corresponding to the 'serial number', the point information of each requested content. Through this, contents management and point management according to 'serial number' are possible, and contents management can be performed by country, product model, and vendor.

[Figure 8]

8) The contents stored in the server are basically encrypted by the Encryption Key, except for the 'Preview' information for later management and classification of the contents of the user, and the Encryption Key is stored in an arbitrary location of the contents file. . The server re-encrypts the encryption key using the 'serial number' and a random key value and transmits the confirmed content to the computer. This content is encrypted with a different key value every time on the server side. It is characterized by the effect of copy protection and prevention of reprocessing of data. At the same time, the purchase information corresponding to the 'serial number' stored in the server is updated. For example, the 'download point' is updated by the difference between the 'download point' corresponding to the 'serial number' and the point information value of the content to be downloaded.

[Figure 9]

9) The computer transmits the encrypted content downloaded from the server to the device.

The above process is automatically performed only by the user's content download selection in the automatic execution program, thereby eliminating the need to perform a complicated procedure for the user to be authenticated individually. In addition, by providing a dedicated content of the content using device can not be used in other devices can be blocked illegal copying. That is, the content using device operates the content including the unique device information as the dedicated content. In other words, content including device information of another device does not operate even in the same format.

The auto-launch program may be directly operated as a content download and management program as the above start program, or may check a user ID and password and allow the content download and management program to operate. In other words, the automatic execution program driven by the host computer by the USB connection is a program of various methods, the content download and management program is only a preferable example. In addition, the content download and management program may include various functions as described below. For example, the content download and management program may include an internet phone function or a bank's identity authentication function.

For example, if the auto-executing program selects a mode such as, for example, Internet banking, the content using device can be used to encrypt the command code and device-specific information to authenticate the user (user) at a bank server through a computer. In addition, when the content device is used only for authentication, such as for bank authentication, the configuration of the autorun program can only perform the self-authentication described above, and sends the device's unique device information to the server when the device is connected to the computer. You can also verify the authentication automatically. In this case, the data is transmitted for authentication, and the data is exchanged while encrypting using a random key and unique device information of the device as described in the above description, and the security is more secure. However, when verifying the identity of the auto-execution program, the user may check the ID and password before starting the authentication process.

If the content-using device is a computer, it is possible to directly execute the content download and management program in the computer without connecting to the computer such as an mp3 player. The serial number may be replaced with unique product information such as a CPU, video card, and / or main board in the computer. In the following description, the same authentication method is applied.

Hereinafter, a description will be given of the function of using the Internet phone while the independent content using device is connected to the computer as described above. All of these features are supported by autorun programs. Many content-enabled devices have features such as microphones and speakers (or headphones). In particular, the MP3 player is equipped with a built-in microphone and headphones, so that the Internet phone can be used as a headset or a built-in microphone and headphones in such a content-using device.

In more detail with regard to the configuration and operation as an Internet telephony service, in order to use the Internet telephony service, the apparatus includes voice input / output means, video input / output means, central processing means (CPU), data storage means, key input means, and display. Means, a connection port with a computer, and the like.

As an analog device, the voice input / output means includes an input device such as a condenser and a dynamic microphone, an output device such as an amplifier, headphones, earphones, and an external voice input / output device such as a headset.

The key input means includes a button or a remote controller attached to the device, and can check, select, and control the volume and sound effects together with the display means such as an LCD and video output built into the device. Do it.

3 illustrates the overall concept of the Internet telephony communication system of the present invention. In the figure, many of the present content-using devices for receiving an Internet telephone service are connected through an internet network, and a call server (CS) for mediating their calls is connected to the internet network. The call server is also connected to a regular telephone through a public telephone network (PSTN).

The computer and the call server connected to the device use the H.323 protocol, for example, to register the call server (CS) for use as its Internet phone, call signaling such as call requests with other general telephones or the device. call signaling), packetizer processing for packetizing the compressed speech coded signal in the digital signal processor, and at the same time, decomposing the packetized speech coded signal inputted through the digital network connection means. It is in charge of packetizer processing and control processing of the overall Internet phone function of the present invention.

Here, the H.323 protocol basically uses Transmission Control Protocol / Internet Protocol (TCP / IP), and TCP / IP supports TCP and User Datagram Protocol (UDP) that can be used in an application. UDP (User Datagram Protocol) is used for call signaling with the call server (CS), TCP is used for call signaling with other Internet telephones, and RTP (Real-time Transport Protocol) is used for transmitting voice data. The RTP transmits voice data to a network using UDP. First, UDP (User Datagram Protocol) processing at the time of transmitting a call signaling message to the call server CS will be described. In UDP, the call signaling message is attached to the IP layer by adding a UDP header including the port number of the other party's application (ie, the call server) and the port number of its application. It adds IP header including address and IP address of other party (ie call server) and drops it to Ethernet device driver in packet form.In Ethernet device driver, Ethernet protocol (for example, IEEE 802.2 / 802.3 protocol) The header is attached to a packet in protocol format for communication with a local gateway connected via LAN, and output to the I / O buffer.

On the other hand, the UDP process at the time of receiving the call signaling message from the call server CS decomposes the packet in the reverse order of the above transmission process, determines whether it is the correct data using its own header for each layer, and determines its own header. After removing, put the packet to the upper layer.

The TCP processing at the time of transmitting the call signaling message to the other Internet telephone is also described. In TCP, the call signaling message is sent to the IP layer in the form of a packet by attaching a TCP header including the port number of the application of the other party (that is, the Internet phone of the other party), the port number of its application, and the transmission confirmation field. It adds an IP header including the IP address of the other party and the IP address of the other party (i.e., the other party's Internet phone) to the Ethernet device driver in the form of a packet.In the Ethernet device driver, the Ethernet protocol (eg IEEE 802.2) header is attached. Convert to packet form and output to I / O buffer. On the other hand, the UDP process at the time of receiving the call signaling message from the other party's Internet telephone is processed in the reverse order of the above-described transfer process.

If the Internet telephone system is configured in the above manner, the Internet telephone service with the main unit and the general telephone and another main unit can be implemented through the Internet network.

Detailed process and description of the Internet phone service of the content-using device of the present invention will be described below.

First, if you want to make a call from this device to a regular phone or another device, the user selects the function and status of the device as 'Internet phone' through the 'Startup program' which is automatically executed after the USB connection with the computer. do. Then, the computer controls this unit to be in the state of the Internet telephony function (that is, the computer recognizes this unit as a USB Audio device or the like). After that, if you enter the telephone number of the telephone you want to call through the key input means of this unit or through the input device on the PC, the computer is connected to the call server via the Internet network and the call server is connected to the DTMF tone of the input telephone number. A corresponding analog signal is generated and delivered to the exchange of the PSTN network. Thereafter, a communication path with the general telephone is formed by the process of forming the communication path between the exchange and the general telephone period. In the above process of establishing a call path with a general telephone, the computer controls to establish a call path to the voice input / output device of the apparatus in order to transmit a ringing tone output on the call path and a signal returned from the exchange to the user. Subsequently, the user's voice signal is converted into a digital signal through a call server and a computer, and post-processing such as data compression and noise reduction is performed.

In this case, the data exchanged on the device and the computer can be compressed, decoded, and echo-decoded using G.711, G723, G.726, G.727, G.728, and G729 methods, for example. Process and the like are performed through the CPU or computer of the unit. Thereafter, the other party's decoded voice signal is converted into an analog signal in Codec and output to the voice input / output device. By this process, a call is made with a general telephone through the PSTN. Then, when the user operates in the call termination state through the key input means, the operation state is detected by the computer to terminate the connection with the PSTN network, thereby terminating the call mode.

In order to download the content or use the Internet phone as described above, the user must bear the cost. To this end, the content using device according to the present invention may be provided with a payment system or linked to a payment homepage in a program that is automatically executed (when the independent device is connected to a computer). As in the existing payment system, a method of earning points and purchasing points, or a method such as credit card or direct debit, may also be used. Hereinafter, a method of purchasing and paying points by credit card or cash will be described.

For example, the homepage payment system is described below. As a payment method using a credit card on the Internet (1) When a credit card payment (purchase amount) is authenticated after accessing a content sales homepage on the Internet, the product's unique serial number and purchase amount information are automatically transmitted to a server. If you connect via USB, charge the point. (2) When the customer connects via USB and goes directly to the seller's payment screen from BUY POINTS in the server screen, points are immediately awarded when credit card payment (purchase amount) authentication is confirmed. (3) When connecting a device using a USB device to a computer with Internet connection, a window (for example, a pop-up window) for connecting to a server automatically appears on the monitor screen. (The language is the language specified in the setup mode.) If you select the payment menu on the pop-up window, you will be automatically connected to the server. In this way, you can check the USER POINTS to download the content.

In the case of downloading the contents through the Internet, the payment system can be used as described above. However, the contents are not purchased only through the Internet, but may be purchased offline using a storage medium such as a CD or a DVD. Even if the content is purchased through a separate storage medium as described above, authentication or a password may be used to prevent illegal copying or copying. In other words, illegal content can be prevented by making the purchased content available only to the designated content using device.

In the following, examples of the contents include DVD images and karaoke songs, which are protected by copyright, and the storage media will be described based on the CD.

1) The contents recorded on the CD are encrypted with a unique encryption key and a unique number generated during each CD production.

2) The consumer purchases a CD in which the content is recorded.

3) Insert the purchased CD into the PC and connect this unit via USB. Then, the 'content certification' program will run automatically.

4) The 'content authentication' program generates a 'question code' by combining the encryption key of the purchased CD, the serial number of the product, and a unique number of 128 bits or more randomly generated.

5) The user requests authentication by informing the user of the 'Question Code' generated by the 'Content Authentication' program and the serial number of the device through a telephone such as a customer service center or an ARS.

6) The Consumer Counseling Office or ARS decodes the 'Question Code' and the serial number to obtain the unique number of the purchased CD, and then accesses the CD unique number management server, inquires the authentication record of the corresponding CD, and determines whether the authentication is possible. . If the corresponding CD has already been authenticated or if the value is in violation of the rule for creating the 'question code', the user should take action due to the inability to authenticate. If authentication is possible, the user is given a 'answer code'. At the same time, the information on the CD number management server is updated to prevent duplicate authentication.

7) The user who received the 'Answer Code' enters the code into the 'Content Authentication' program.

8) The 'content authentication' program uses the 'answer code' to decrypt the encrypted content and at the same time executes encryption based on the serial number of the currently connected device and sends it directly to the device after the encryption is executed.

In addition, the payment method can be made as follows, if the Road Card and CD purchases offline proceeds as follows.

1) The consumer purchases Road Card and CD from the store, and connects the device's USB to a computer connected to the Internet, connects to the server, and removes the pin number and road card scratch recorded on the CD in the search box. You will be given a pin number, a verification point and a download point corresponding to the purchase price.

2) If the device is connected to a computer with an Internet connection via USB, a pop-up window will automatically appear on the monitor screen. (The language is the language specified in the setup mode.) If you select from the pop-up window, you will be automatically connected to the server.

Hereinafter, a portable karaoke device as a preferred example of a content using device according to the present invention will be described in more detail. The portable karaoke device may further include various functions such as an MP3 player, a digital camera, a camcorder as well as a karaoke role.

Fig. 4 is a block diagram showing the main circuit configuration of the portable karaoke apparatus. The apparatus comprises a voice input / output means, a video input / output means, a central processing means (CPU), a data storage means, a key input means, a display means, a connection port with a computer, and the like.

As shown in FIG. 7, the lower portion of the main body 200 is provided with a terminal 230 connected to the outside, and is connected to an external monitor TV through a separate connection jack 330 to perform a karaoke function alone as well as an image sensor. Including all the parts, it can also perform all functions such as MP3 player by itself. The key matrix 220 is provided with a liquid crystal screen to view video, image song lyrics, and the like, and to check an operation state.

The portable karaoke device as described above may be used by searching and sorting contents, which will be described below with reference to a block diagram for explaining sorting and searching of contents of FIG.

Conventional karaoke devices have a separate collection of songs (book number and title of the list information such as song number and title, singer, etc.) in order to find a desired song when sorting and searching of titles and singers are not implemented in the device. File). There may be a way to implement the entire alignment in real time in the operation of the device, but this method depends largely on the speed of the CPU and the size of the storage device, so the performance of small memory or slow CPU, etc. It is difficult to implement on low hardware. In addition, even if content and information already sorted in the device are stored, it is necessary to add or delete frequently because of the nature of the product that is connected to the computer and mainly download the content. This wasted a lot of resources and time, such as storing the information needed for sorting by the device.

However, in the present invention, when adding and deleting contents, the contents simply end up storing the contents file, and the device loads only the 'sort index' of each contents file into the main memory of the apparatus when the operation is initialized. Since the search detects only the information that the user wants to search, it can be quickly displayed to the user.

In the present invention, a plurality of contents may exist in one content file, and the header of each content file includes a 'sort index' arranged by title, singer, genre, and the like. The 'sort index' is calculated and stored when creating the content file.

1) At the start of the search function, the device receives a search form and keywords from the user. For example, the search form may be alphabetical order, title order, genre order, and the like, and alphabets or Korean words may be input to the keyword.

2) Search for a keyword within each 'sort index' of the content files stored in the device. In this case, binary search, hash search, and the like are used. The 'Sort Index' is classified and searched according to the search type.

3) Within each 'Sort Index', find the found song corresponding to the keyword and the song corresponding to the next index number.

4) The closest value of each of the songs obtained above is obtained and the song is displayed on the screen.

5) Rescan the index according to the maximum number of songs to be displayed on the screen and display it next to the screen. At this time, the re-search of the index uses the smallest value excluding itself among the songs obtained above.
