Description

Computer-controlled content playback device made impossible to duplicate {.}

In order to transfer the content data to the content player, first, the content data must be stored in the computer. The means for storing the content data is provided through a service provider for a fee such as computer communication. If the content data downloaded for a fee is used by anyone other than the service recipient, it is illegal to copy from a service provider's point of view, and there is a high possibility of causing social problems such as copyright. Therefore, the purpose is to prevent the use of people other than those who are paid for.

Recently, many contents have been provided through the Internet. This content may be described as text data such as text, mp3 data for listening to music, or audio and video data. The provided content data is played through the computer or a dedicated content player, so that it was possible to enjoy it without difficulty. However, such content data can be downloaded to a computer of your own by paying a certain amount using the Internet or computer communication, and then moving the downloaded content data to a dedicated content player to enjoy the content through this content player. In this case, the problem is related to the usage fee. For example, other people use the above-mentioned various contents data downloaded from a service provider paying the contents data to a specific computer for a fee. In other words, the other person uses the content content fee for free without paying the service provider. Therefore, from the point of view of the content service provider, the more people who make copies for free, the more the sales decrease, and the illegal copying is a social problem. Therefore, the present invention was invented to prevent such illegal copying of content data. As a solution, if a user wants to receive content data, the service provider transmits the information of the user who requested the service to the content data. Thus, the content data containing the specific information is reproduced only in the content player of the specific person and cannot be reproduced because this specific information is not interpreted in the other player's player. Therefore, only a specific user can be reproduced, so there is no effect of illegal copying.

When the content data provided from the service provider is recorded on the user's computer, the user's member number and password in front of the content data, and the device number of the content player that the user has, Put your information and save it on your computer. When the stored content data is downloaded to the content player again, the user's information is compared with the product number in the stored content data and the product number of the content player to be connected. If it is different, it can be recognized as a connection failure and prevents the copying of the content data to the content player so that illegal copying is impossible.

1 shows a connection form between a conventional content player and a computer in which content data recorded and stored in a computer memory is connected to a dedicated content player to transfer the content data to the content player. A more detailed description of the configuration of such a conventional content player is that "101" is the content player described above, "102" is an action key for operating the content player, and "103" is an operation key of the content player. It is also used as an operation indicator that shows the operation status or the status of the currently output content. For example, it is a liquid crystal display such as an LCD that can display video signals or text data. It is the connector wire that connects for the transmission of the cable. Referring to the operation description, first, the "105" computer stores the content data downloaded via normal computer communication or the Internet, and the player for downloading and reproducing the content data is "101". Next, Fig. 2 shows the internal block of the content player of " 101 ". Referring to FIG. 2, first, "201" is a connector to which the "104" connector wire of FIG. 1 is connected, "202" is a memory for storing the above-mentioned content data transmitted through the "201" connector, and "203". Is a content decoder which decodes the content data stored in "202" into the original content signal. "204" is an audio amplifier that amplifies the audio signal to a predetermined level when the content signal output from the content decoder of "203" is an audio signal, and "205" is connected to an audio amplifier of "204" so that it can be heard as sound. It is a microcomputer that controls the entire content player such as "206". &Quot; 207 " is an indicator to be displayed when the content signal is complex data to be displayed in text, video, etc. other than the audio. The indicator can be connected to an indicator such as a liquid crystal display capable of displaying a picture, animation, video or video of a cartoon lamp or an LCD capable of displaying a simple character. Next, "CMD" and "DATA", "CMD" is a signal for determining the structure of the data output as DATA. If this CMD is "1", it means the address data of the memory of "202", and this CMD is " 0 "means actual content data written or written to the address of the memory of" 202 ". Next, referring to FIG. 3, FIG. 3 shows the structure of the memory for storing content data of the above-mentioned "202". The memory can be divided into two structures, one of which is a table of contents (TOC) and a memory area. .

Here TOC is a table showing the configuration in real memory. That is, data of information such as what content data is recorded in the memory and how the content is organized is recorded. The next memory area contains pure data of the content itself.

Thus, the basic structure of the existing content player, the internal block, and the memory structure have been described. However, in the existing content player, there is no problem in downloading the content data because the computer or anybody can download the downloaded content data without any restriction in downloading the content data recorded in the computer.

Therefore, for copyright reasons, if a person downloads paid content data, only that person should be used. In other words, if another person downloads the contents data downloaded for a fee to his or her content player, it will be illegally downloaded. The country's image is believed to be significantly damaged. Therefore, in the present invention was invented to solve the problem of illegal copying, the method first executes the content manager program on the computer, and enter the member number and password and the product number of the device uniquely assigned to each content playback device . When the basic user information is input, the content manager program recognizes the user's member information, and if it matches the information entered when the user already registers, the content manager program is logged into the content manager program to receive or receive the content data from the content service provider. You can download the data to the content player. Next, you can actually download the content data from the content service provider for a fee. In this case, the content manager program stores the information of the member currently logged into the content data on the computer. In other words, it does not simply store the content data, but includes the current user's member information, thereby preventing the illegal copying by using the member information.

Next, when the content manager program downloads the content data already received on the computer to the content player, the product number of the connected content player is searched for, and the product number of the device and the connection recorded in the content data to be downloaded are as follows. If you compare the number of devices and it is the same, it is your device, so if the connection is successful, download it, and if you connect another player's content player, the number of connected device and the connected device recorded in the content data will be different. Sends an unaccessible message to the currently connected content player. To summarize these results, if a particular member has been downloaded from a content service provider for a fee, the content data is only downloaded to the content player owned by the specific member and not down to other content players, so it is not illegally copied. Illegal copying, which is the object of the present invention, can be prevented.

The following describes the operation of the illegal copying relationship in detail with reference to the figure. First, a computer-specific manager program as shown in FIG. 10 should be provided. What is done in this manager program is a program that is used to receive content data from a content service provider or to download the provided content data to a content player. This content program is executed only after entering the member name, password, and device number of the content player. When the above member information is first inputted, this information is inputted to the content service provider's database, and each time the user uses the member information as shown in FIG. 11 and confirms the information, it is compared with the already recorded member information. Notify that they are connected together. If not, notify the connection failure as shown in Fig. 13, and request confirmation again. Here, the input of the device number of the content player is to prevent illegal copying, which is the purpose of the present invention, and is a number assigned to each product when the content player is purchased and the number is mixed with the content data. In other words, the user inputs the device number input when the member information is input to the content service provider, and when the member wants to download the content data, the user sends the device number of the content reproducing device together with the pure content data. This is shown in FIG. 3, it can be seen that the member's name, password, and device number are included in the pure content data. In other words, when the content service provider transmits the content data at the request of the member, the content service provider not only sends the content data but also the requested member's information. 3, the first 16 bytes of data are assigned a member name, the next 16 bytes of a password, and the next 16 bytes of a device number of a content player to be downloaded. Only then will the pure content data be attached and sent together. Next, how to input the device number of the content player. The device number of this content player is assigned when it is shipped from the factory and is given one unique number per product, such as a serial number of a product. The method of assigning is to input the device number of the product into the memory area of the content player. The position in the memory where the device number is input is shown in FIG. 5 as a position higher than the TOC area in the memory. That is, the first 5 bytes of memory are allocated to the device number area. Although FIG. 4 is divided into two types of TOC and DATA areas in the conventional memory structure, it can be seen that in FIG. 5, 5 bytes up to address 0000-00004 are allocated. As a method of inputting a device number in the device number area thus prepared, the device number is searched from address 00000 to 00004 in the memory as shown in FIG. Since it is not possible, give a new device number. In this method, the number corresponding to the product shipping number can be assigned. 7 shows a timing diagram when an actual device number is input. If CMD is '1', address location data is written and if CMD is “0”, first byte of device number is written. 7 shows an example of input of device number 1, device number 2, and device number 3 as an example. In the example of Device No. 1, the first CMD "1" writes 00000 data, which is address data, and "0" writes 00, the first device number data. In the second CMD "1", the address data 00001 is written and in the "0", the second device number data 00 is written. The third CMD "1" writes 00002 data, which is address data, and the third device number data 00, "0". The fourth CMD "1" writes 00003 data, which is address data, and the fourth device number data, 00, is written "0". The fifth CMD "1" writes 00004 data, which is the address data, and the fifth device number data, 01, is written "0".

This result is shown in FIG. This completes the input of the device number of the content player. Here's how to use the device numbers for these products.

9 is to enter the device number in order to enter the content manager program of FIG. 11 If the user enters his own content player device number and connected to his content player, the above program is executed, if other than his content player If you connect a human playback device, the device number in the member information and the product number of the product is different, so the above program cannot be executed. This is shown in the timing diagram of FIG.

In this case, if the member's name, password, and device number entered in the program are different, of course, the user cannot connect as a result of the present invention. Just enter the number and connect to our content player and the program will run. However, since there is someone else's computer, there is clearly content data provided by the content service provider, and if you want to download it, that is, if you want to download it to your own content player connected for illegal copying, Since the search result of the friend's device number in the content data and the own content playback device number of FIG. 5 are naturally different, the content data download will fail. This relationship is shown in FIG. Therefore, by using the present invention, not only the content data downloaded by another person can be used, but also the content management device of the user can not be connected to the content manager program of another person, thereby achieving the object of the present invention.

Only users who have been provided with content data for a fee can enjoy content data using the content player, thereby preventing illegal copying of content data related to copyright.
