Description

Memory card player that operates {Memory card player}

According to the present invention, digital data corresponding to a copyright is recorded on a memory card and then distributed to the general user through the memory card, and the memory card is reproduced by a dedicated playback device.

The present invention is a new replacement for the existing CD record, and the CD record so far is connected to a PC, and all sound recordings or video data corresponding to copyrights in the CD are leaked into the PC. In order to solve this problem, the present invention releases a record with a memory card, which is a medium different from that of a conventional CD, and plays a recording on a dedicated device. Digital sound sources can be protected.

In order to solve the above problems, the present invention provides a memory card having a dedicated player for recording the contents of a CD recording and reading out the memory card corresponding to the recording using a memory card instead of a CD recording. By only playing in a dedicated player can prevent illegal leakage of data corresponding to copyright.

In addition, since the player is provided with a built-in memory, and the normal mp3 function is also possible, data can be read and written to and from the PC using a USB. However, when the memory card is connected to the memory card player, the data in the memory card should not be leaked to the PC in order to protect copyright. Therefore, it is necessary to block the USB terminal so as not to be connected to the PC.

The memory card player, which is an object of the present invention, can selectively operate the memory in the memory card and the internal memory in the memory card player according to whether the memory card is attached or detached. Can be achieved.

In addition, the data in the memory card referred to in the present invention may be a variety of data, such as voice, video, text, graphics, etc., the memory card player is a player that outputs audio, video to view music, movies, and the like. Specifically, mp3 player, video player, PMP, DMB, mobile phones and other common electronic devices, including all devices that memory card is operated.

In addition, since the data in the memory card is not connected to the PC for the purpose of the present invention, illegal leakage of the data can be fundamentally prevented, and the data recorded on the memory card can be read only by a dedicated playback device such as DRM encryption. Even if the data in the memory is read to the physical device by using the digital data loaded with the information, even if the data is encrypted, it cannot be used even if it is read.

Conventionally, the audio and video data recorded on the CD is connected to the PC and illegally leaked through the PC. However, in the present invention, the audio and video data is recorded on a memory card to prevent the illegally leaked data. By reproducing the audio and video data in the memory card and blocking the connection with the PC, it is possible to provide a medium which prevents the leakage of data illegally.

In addition, not only a dedicated player but also a normal electronic device having a function of playing the memory card can reproduce the memory card and achieve the object of the present invention.

1 shows a memory card which is an object of the present invention. 1, first, [101] shows the appearance of a memory card that contains audio and video data corresponding to copyright. The memory in the memory card corresponds to the object of the present invention if it is a memory of the same type as the flash memory that is free to read and write. [102] is the memory card pin of [101] coupled to the memory card player connection portion.

2 shows an internal block diagram of an actual memory card player, where [201] shows the appearance of the memory card player, [202] shows the memory card pin connection connecting portion into which the memory card is inserted, [203] shows the control section, and [204]. Is the internal memory. [203] is a memory control unit connected to a playback device to control the memory when writing and reading data from the playback device. [205] is a USB connection for reading and writing data in the internal memory. This [205] is connected to the usb of the pc to send and receive data.

Fig. 3 shows a detailed block of the connection portion between the memory card and the memory card player. [301] is a memory card, [302] is a memory key pin connected to a memory card player, [303] is an external memory mounted in the memory card and contents are recorded, [307] is a memory card player, and [304] Is a connection for connecting a memory card to a player, [305] is a control unit for operating an internal memory, and [306] is a memory card player. [308] is a USB connection for sending and receiving data to and from the PC. [306] The USBEN signal is controlled by the control unit. When the USBEN signal is low, it is connected to the PC. If the USBEN is high, the connection with the PC is lost. do. Although no specific example is given here, the USB line connection can be controlled using a switch buffer that is turned on at a normal low level. The important thing is whether to use USBEN or not to connect USB.

Alternatively, if the control part of [306] recognizes that the memory card is inserted without using the USBEN terminal, there is a method of blocking the USB routine in the program and activating the USB routine in the program when the memory card is removed.

4 is a timing diagram of a signal outputting a signal from the control section of [306] when the memory card is connected or not to the memory card player.

Fig. 5 shows as an example a dedicated playback apparatus using this memory card directly. [500] is the play key, [501] is the forward key, [502] is the forward key, [503] is the forward key, [504] the display and [505] is the LED indicating the status of playback. The device, [507], is an audio output terminal. [508] is a memory card connected to the playback device of [506], and [509] is a connection part to be connected.

6 is a flowchart of a control unit related to the timing diagram of FIG. 4.

First, the control unit checks the state of the card in. If the memory card is inserted, it is recognized as [Yes] and the signal of INCE--> high, EXCE--> low, USBEN-> high is turned on to operate the memory card memory and prevent USB. Is detected as "No", and the signals of INCE ---> low, EXCE ---> HIGH and USBEN-> low are output to prevent the memory card from operating and to release USB.

FIG. 7 shows that the external memory section of FIG. 2 is actually configured. The actual memory is divided into a TOC area and a data area. The TOC area is the number of songs recorded on the memory card, next is the number of songs recorded in this recorded song, next is the number of music videos, and the next recording time, composition, and lyrics It is an information area that contains the singer's entertainment, release date, genre, singer profile, company profile, composition, songwriter profile, and other information. The next data area is the actual memory area in which the audio and video data of each recorded song is located. This data is pre-written at the factory before the memory card is shipped. The user can listen to each song or watch a music video by reading the audio and video data.

Specifically, the memory card and memory card player of this configuration will be described in detail. When the memory card of [301] is connected to the memory card player of [307], [306] becomes low at pin 8 of the connection connection of [304]. Detect that Pin 8 is normally high when no memory card is connected, and low when a memory card is inserted. The reason is that it is always low on the 8th pin of the memory card of [302] inside the [301] card. When low, [306] recognizes that the memory card has been inserted, outputs INCE- high to disable [305] internal memory in the memory card player, and EXCE- to operate the external memory card of [303]. Output low. In this case, the internal memory in the memory card player will stop working and the external memory of the memory card will be activated. This allows the memory card player to read the data recorded on the memory card. The memory card player also disables the USB connection by turning USBEN high to disable writing of data to internal memory.

When the memory card connected to the memory card player is detached, [306] detects that pin 8 of the connection connector of [304] becomes high. Pin 8 is high when no memory card is connected. The reason is always high when the memory card is not connected because pin 8 is connected to Vcc. In this high state, [306] recognizes that the memory card has been removed and outputs INCE- low to enable [305] internal memory in the memory card player, and disables the external memory card of [303]. Output EXCE- to high. In this case, the internal memory in the memory card player is activated, and the external memory of the memory card is stopped. In this case, the memory card player can read data recorded in the built-in memory. The memory card player also enables USB connections by turning USBEN low to allow data to be written to internal memory. That is, by operating the USB connection connection of the [308] to be connected to the external PC.

By doing so, the memory card player of [307] can selectively operate the memory in the memory card and the built-in memory of [305] according to whether the memory card of [301] is attached or detached. Due to this, the object of the present invention can be achieved.

The data in the memory card referred to in the present invention may be various data such as audio, video, text, graphics, and the like. The memory card player of [307] is a player for outputting audio and video for viewing music and movies. . Specifically, mp3 player, video player, PMP, DMB, mobile phones and other common electronic devices, including all devices that memory card is operated.

In addition, since the data in the memory card is not connected to the PC for the purpose of the present invention, illegal leakage of the data can be fundamentally prevented, and the memory card has encryption information such as DRM so that it can only be read by a dedicated player. Even if the data in the memory is read to the physical device by using the digital data loaded, it is encrypted data and therefore cannot be used even if it is read.

The memory card may be a memory card of various contents such as a movie, a lecture, a video education, an electronic book, and the like, depending on not only the record but also the recorded data.

In addition, the above-described memory card can be played not only in the memory card player of the present invention but also in an electronic device having the memory card playing function, especially mp3, pmp, DMB, TV, audio device, mobile phone, etc. The object of the invention can be achieved.
