Description

End device

The present invention relates to a kind of end device, it can hold selectively such as the copyright inconsistent storer of copyright perhaps mutually.

Now, an activity is widely arranged, the server of expecting on a lot of PC (personal computer) accessing WWW (WWW) networks of people by them is used for personal entertainment with the compressed digital-data of downloading such as an a piece of music or a pictures to the hard disk of PC.

Another activity that is just becoming very popular now comprises that it contains the nonvolatile memory such as flash memory to mobile terminal device fit on pocket memory (as storage card).(mobile terminal device that contains fixing nonvolatile memory also is suitable for.) mobile terminal device links on the PC through the IEEE1394 compatible cable or such as RS (proposed standard)-232C interface or USB (universal standard bus).Transmit or copy to nonvolatile memory such as the compressed digital-data of an a piece of music or a pictures from the hard disk of PC.The user carries the mobile terminal device that contains nonvolatile memory to appreciate music or other content of record out of doors intuitively then.

Because by encrypting and/or authorizing the copyright control that realizes also not carried out by strictness, exist a kind of trend via the numerical data of the Internet download just by illegal copies and distribution.

At present, be stored in numerical data unencryption still in the nonvolatile memory as mentioned above.People worry by means of using the system of mobile terminal device as mentioned above, and illegal copies may flood legal market.

Consider the copyright control that execution is comparatively strict, proposed to contain the nonvolatile memory that is useful on the signal processing circuit of authorizing and encrypting.The nonvolatile memory of so developing is the compatible nonvolatile memory of copyright (the compatible storage card of copyright).

When the widely use of the compatible nonvolatile memory of copyright that promotes to be proposed, the user is necessary they are clearly distinguished with the nonvolatile memory of the copyright non-conforming of using now and comes, so that can use a kind of or other kind storer according to situation selectively.

Meanwhile, require the compatible nonvolatile memory of copyright in appearance should be not different with the compatibility of existing portable set with traditional, nonvolatile memories.In other words, the compatible nonvolatile memory with copyright of copyright non-conforming nonvolatile memory all should have identical outward appearance, the mobile terminal device so that they can be packed into.

The direct record of available rights non-conforming nonvolatile memory, the voice under recording such as the individual and meeting process image etc. are called as the numerical data of no copyright.

On the other hand, the compatible nonvolatile memory of available rights from such as CD (compact discs) and the MC existing storage mediums such as (compact disks), writes down numerical data (for example, counting song).Utilize these storeies, stop illegal copies copyright protection data by encryption or suitable means such as licensing process.

For copyright protection, the compatible nonvolatile memory of copyright must be equipped with and be used to the signal processing circuit of authorizing or encrypting, the function that a kind of copyright non-conforming nonvolatile memory does not possess.

Two kinds of main type portable terminal devices are arranged.One type mobile terminal device can essential record meeting process, and another kind can be downloaded the numerical data of encrypting from PC or similar source.

The mobile terminal device of essential record meeting process should be equipped with copyright non-conforming nonvolatile memory, and should insert the compatible nonvolatile memory of copyright from the mobile terminal device of PC or similar source data download.

As mentioned above, the compatible nonvolatile memory with copyright of copyright non-conforming in fact all has identical outward appearance, makes domestic consumer be difficult to these two kinds of storeies of difference.In addition, not every user all be concerned about which kind of mobile terminal device should with the nonvolatile memory compatibility of which kind of type.

Also there is this situation, uses the mobile terminal device record meeting process of energy data download.In this case, mobile terminal device can be equipped with copyright non-conforming nonvolatile memory.

Owing to be difficult to the dissimilar of difference nonvolatile memory, the user is short in understanding to the compatibility between relevant mobile terminal device and the nonvolatile memory, unrealistic ground desired user can insert mobile terminal device to the nonvolatile memory of inappropriate type and be certain to frequent generation so carelessly according to using situation to adopt the storer of suitable type.Use the storer of incorrect type can cause mobile terminal device not write down rightly or playback of data.

Executive logging or playback function will cause copyright protection function normally not realize irrelevantly, or the user is need not the data recording of copyright protection to the compatible nonvolatile memory of copyright.The latter's situation causes the data of record by copyright protection, so that must handle this data in a kind of very thorny mode after a while, regardless of its character.

And then the copyright non-conforming nonvolatile memory of inappropriate use may cause can't downloading and writing down the data that need copyright protection.

The present invention be make according to above situation and a kind of mobile terminal device is provided, it allows user that suitable storer is packed into end device to satisfy specific application target.

In carrying out the present invention, according to wherein on the one hand, a kind of end device is provided, any of first kind and second kind storage card can be inserted wherein selectively, first kind of storage card storage content protected by copyright, second kind of storage card has content not protected by copyright, and this end device comprises: judging unit, judge that the storage card that inserts the end device main body is first kind of storage card or second kind of storage card; Control module if judging unit judges that the storage card that inserts is second kind of storage card, is forbidden reproducing content content record to the second kind of storage card with from second kind of storage card.

According to this aspect on the other hand, a kind of end device is provided, any of first kind and second kind storage card can be inserted wherein selectively, first kind of storage card storage content protected by copyright, second kind of storage card has content not protected by copyright, this end device comprises: judging unit, judge that the storage card that inserts the end device main body is first kind of storage card or second kind of storage card; And control module, if judging unit judges that the storage card that inserts is first kind of storage card, forbid reproducing content content record to the first kind of storage card with from first kind of storage card.

Now the preferred embodiments of the present invention will be described.The present invention exemplarily is embodied as a kind of portable set, and its utilization is equipped with the storage card of flash memory as separable storage medium.Portable set is a record and the device that reproduces digital audio and video signals and other data intuitively.This portable set below will be called register with simple form.

The preferred embodiment of describing comprises: the compatible portable set of copyright (register 1A), its with the storage card 40A of this hardware compatibility, possess copyright protection function; Copyright non-conforming portable set (register 1B), its with the storage card 40B of latter's hardware compatibility, do not possess copyright protection function.

One portable set (register 1C) also will be described, its both with storage card 40A also with storage card 40B compatibility.

Fig. 1 is with storage card 40A, the block diagram of the compatible portable set of copyright (register 1A).

In Fig. 1, dotted line is around two main pieces, and a piece shows how register 1A constitutes, and another piece shows how storage card 40A constitutes.Storage card 40A is with the separable mode register 1A that packs into.

Register 1A (with the 1B that will describe after a while, 1C) and storage card 40A (with the 40B that will describe after a while) constructed and realized when of the present invention the record of description and playback system below.This system not only can write down and reproduce digital audio and video signals but also can record and reproduction of moving and static view data.

Register 1A comprises: CPU2; Secret piece 3 is linked CPU2 by bus; Operating unit 4; With display device 5.

Secret piece 3 comprises DES (data encryption standards) encrypted circuit and carries out the circuit of licensing process.

Operating unit 4 comprises button, and button touches switch and other allows the user to carry out about writing down and reproduce the control of various operations.

In response to the user operate on the operating unit 4 to be produced such as operation informations such as record or playback commands, delivered to CPU2 through bus.

Display device 5 can be made up of LCD panel.Under the control of CPU2, the every information and the mode of operation of display device 5 displayed record devices 1.

Register 1A also is furnished with voice data interface 6, encoder/decoder 7, A/D converter 9, D/A converter 12.

Voice data interface 6 provides the voice data interface between the outside input/output terminal of a side and other the side internal encoder/code translator 7.

It is low bitrate that encoder/decoder 7 is responsible for digital audio signal coding, and decoding low bitrate coded data.

Employing is called as the low bitrate coding method of ATRAC3.This is the improvement to the ATRAC (adaptive transformation auditory coding) of little optical disk system use.In ATRAC3, handle 16 sample voice datas with the sampling of 44.1KHz speed.The minimum data increment that is used for the voice data processing in ATRAC3 is called voice unit (VU) (SU).A voice unit (VU) continues about 2.3ms, is made up of 1,024 sample data that is compressed into the hundreds of byte data (1,024 * 16 * 2 sound channels).According to ATRAC3, voice data is compressed to about 1/10th of its raw capacity.Because data compression or connect the cause that compression is handled, sound quality is a bit degenerated.

Can provide simulated audio signal to register 1A, to reproduce the audio output apparatus that connects by the outside such as the CD player, MD (compact disk) player, the output that radio or tape player produce.In the case, simulated audio signal is delivered to A/D converter 9 to convert digital audio and video signals to from terminal 8.After the conversion, digital audio and video signals is sent to musical audio digital interface 6.

Also can provide digital audio and video signals, to reproduce by the audio output apparatus of outside connection or with form that receive from the digital broadcasting source or the online voice data that scatters, the output that is produced to register 1A.In the case, digital audio and video signals is delivered to voice data interface 6 through terminal 10.Digital audio and video signals is directly delivered to register 1A by the fiber optic cables of external source.

Voice data interface 6 is handled the sound signal of input so selectively.Selected sound signal is sent to encoder/decoder 7.

It is low bitrate that encoder/decoder 7 is responsible for the digital audio signal coding that provides, and coded data is sent to secret piece 3.

Secret piece 3 is provided by the coded data that is provided.Provide the secret piece 52 that to describe after a while among secret piece 3 and the storage card 40A to protect the copyright of content (being digital audio and video signals in this example).Secret piece 3 among the register 1A has a large amount of master keys and a storage key, and it is unique to described equipment.These keys are used for the purposes of encryption and decryption.

Secret piece 3 also comprises the stochastic circuit that produces session key.Whether when the storage card 40A that contains secret piece 52 inserts register 1A, carrying out licensing process is the card that is authorized to the storage card 40A that distinguishes insertion.If storage card 40A is distinguished it is believable, then secret piece 3 can be shared session key with secret piece 52.

Secret piece

3 and 52 each all be equipped with the function of carrying out suitable licensing process.

As describing in more detail after a while, storage card 40A is a monolithic IC-card, is loaded with flash memory (nonvolatile memory) 42 on it and contains the DES decrypt circuit, the secret piece 52 of communication interface and register.

Storage card 40A inserts register 1A with the form that can freely separate.In fact, register 1A can hold the storage card with encryption function, does not promptly have the storage card 40B (describing after a while) of secret piece.

When input audio data as mentioned above, encoder/decoder 7 is encoded to low bitrate with it, is encrypted by secret piece 3 then.After handling, the voice data of encryption is sent to CPU2.

CPU2 is by memory interface 11 and the storage card 40A swap data that is fixed on the separable mechanical hook-up (not shown).Memory interface 11 has been guaranteed the serial data communication between CPU2 and the storage card 40A.

After being encrypted by secret piece 3, voice data is delivered to storage card 40A through memory interface 11 by CPU2.The voice data of delivering to storage card 40A is written into the flash memory 42 that is positioned at wherein.

The voice data of input is recorded among the storage card 40A via the above approach.

Voice data among storage card 40A mode as described below reproduces: CPU2 reads voice data by memory interface 11 from flash memory 42.The voice data that retrieves (i.e. the voice data of Jia Miing) is sent to secret piece 3 and is used for deciphering.The voice data of encrypting is decompressed it to come out from compressive state by encoder/decoder 7.

The decrypting process of being carried out by encoder/decoder 7 produces 16 sample audio signal with the 44.1KHz sampling.This sound signal is delivered to D/A converter 12 by voice data interface 6, to convert simulated audio signal to.Carry out after the conversion, simulated audio signal outputs to external unit from terminal 13.

In addition, from the voice data of encoder/decoder 7 with from data after the deciphering of secret piece 3,,, output to external unit via voice data interface 6 from

terminal

14 and 15 as numerical data.

As mentioned above, the voice data that records storage card 40A or reproduced by storage card 40A is encrypted respectively or is deciphered by the secret piece 3 among the register 1A respectively.In addition, encryption and decryption process can be carried out by the secret piece 52 among the storage card 40A.

In the optional mode of another kind, voice data can be encrypted by secret piece 3 when record, in case and deciphered by secret piece 52 when playback.On the contrary, voice data also can be encrypted by secret piece 52 when record, and is deciphered by secret piece 3 when playback.

In further optional mode, voice data can be encrypted by two

secret pieces

3 and 52 when record, and is deciphered by same two

secret pieces

52 and 3 when playback.

Secret piece

2 and 52 is designed to have similar encryption function, and it allows to share and exchange encryption keys and decruption key between two pieces.These similar functions allow aforesaid any voice data encrypt/decrypt mechanism.

Outside its encryption and decryption function,

secret piece

3 and 52 any have authorization function.As storage card 40A insertion register 1A,

secret piece

3 and 52 exchanges authorization data between them.The result of data communication is as granting the foundation of authorizing or forbidding authorizing.If forbid authorizing, register 1A forbids that directly record data reproduce data to storage card 40A or from storage card 40A.

Particularly, licensing process is following to be carried out intuitively: when storage card 40A inserts register 1A, first authorization data of being held by secret piece 3 among the register 1A is sent to storage card 40A, after providing first authorization data, secret piece 52 among the storage card 40A produces corresponding second authorization data according to predetermined formula.Before being transferred to register 1A, first mandate is replenished by second authorization data.

By checking whether storage card 40A has returned to respond second suitable authorization data of first authorization data, and register 1A grants or forbids authorizing.

Aforesaid mandate, the encryption and decryption function is mainly used in the protection copyright.

Fig. 2 is the block diagram of storage card 40A.Storage card 40A is a monolithic IC-card, is made of controll block 41 and flash memory 42.

Bi-directional serial interface between CPU2 among the register 1A and the storage card 40A (being memory interface 11) is made up of 10 signal wires.

These 10 signal wires comprise four main signal wires: clock line SCK, tranmitting data register signal during data transmission; Condition line SBS, send state information; Data line DIO transmits data; With interrupt line INT.

Two ground wire GND and two power lead VCC are used to provide power supply.All the other two signal wires keep.

Design clock line SCK, with data sync tranmitting data register signal.Condition line SBS is used to send signal, the state of indication storage card 40A.

Data line DIO is used for the voice data of input and output order and encryption.

Interrupt line INT is a signal wire, and it sends look-at-me and interrupts to the CPU2 of register 1A request to allow storage card 40A.

When inserting register 1A, storage card 40A produces look-at-me.Yet in the present embodiment, look-at-me transmits on data line DIO, and its interrupt line INT ground connection is not used.

Serial and parallel/serial conversion interface block 43 (can be abbreviated as S/P, P/S, I/F piece) provide the interface between the memory interface 11 of controll block 41 1 sides and opposite side link described card by many signal line register 1

Serial and parallel/43 of serial conversion interface block are come the serial data of self-recorder 1A to convert parallel data to, and the parallel data of conversion are delivered to controll block 41.Interface block 43 also converts the parallel data from controll block 41 serial data to and the serial data of conversion is sent to register 1A.

And then in case receive order and data on data line DIO, serial/parallel and parallel/serial translation interface piece 43 is be divided into two groups that received: a kind of is the order and the data of normally visiting flash memory 42, and another kind is order and the data that requirement is encrypted.

Particularly, with the form that signal transmits on data line DIO, order at first occurs, and follows data thereafter.Serial/parallel and parallel/serial translation interface piece 43 is checked given command code determining the needing order of normal visit and to follow thereafter data, still need require the order of encrypting and follow thereafter data.

The result who checks command code is, any order that is used for normal visit is placed into command register 44 and the data that accompany are placed into page buffer 45 and write register 46.

A correcting-code generating 47 relevant with writing register 46 is provided.Correcting-code generating 47 produces the data relevant redundant correcting sign indicating number interior with temporarily being kept at page buffer 45.

From command register 44, page or leaf buffer 45, the data that write register 46 and correcting-code generating 47 outputs are supplied to flash memory interface/sequencer 51 (can be abbreviated as memory I/F, sequencer).

Flash memory interface/sequencer 51 provides the interface between controll block 41 and the flash memory 42, with control exchanges data therebetween.Data write flash memory 42 by this memory interface/sequencer 51.

In data read operation, deliver to page buffer 45 from the data that flash memory 42 retrieves by flash memory interface/sequencer 51, read register 48 and error correction circuit 49.

Inserting any mistake that data occur in the page buffer 45 is revised by error correction circuit 49.Data after the error correction of page or leaf buffer 45 output are with being sent to serial/parallel and parallel/serial translation interface piece 43 from the data that read register 48 outputs.Therefrom, data are delivered to the CPU2 of register 1A by serial line interface as mentioned above.

Provide configuration ROM 50 to store such as information such as relevant storage card 40A version information and every attribute informations.

Storage card 40A is furnished with switch 60, can be wiped unintentionally preventing by user operation as needs.Wipe disabled position when switch 60 is made as, even send the order of asking to wipe data the flash memory 42 from register 1A, flash memory 42 also can prevent to wipe.

Crystal oscillator 61 produces time clock, provides timing reference for storage card 40A handles.

As mentioned above; a kind of means as copyright protection; the secret piece 3 of register 1A and the secret piece of storage card 40A 52 are carried out its licensing process and the content (promptly press the voice data of ATRAC3 standard compression, be called the ATRAC3 data below) that writes flash memory 42 are encrypted.

Secret piece 52 comprises memory buffer 53, des encryption circuit 54 and nonvolatile memory 55.

Secret piece 52 has a large amount of authorization keys and a storage key, and this storage key is unique to described storage card.

Nonvolatile memory 55 contains the key of encrypting usefulness thereby causes not can read from the outside.On directly perceived, storage key is stored in the nonvolatile memory 55.

Secret piece 52 also has stochastic circuit, and it allows to authorize the register 1A of appointment and this card to share session key.

Encrypting the content key of ATRAC3 data encrypts by session key and is transmitted between register 1A and storage card 40A.

As the secret piece 52 of storage card 40A, the secret piece 3 among the register 1A has the storage key of himself.On directly perceived, when the content of encrypting when one moves on to another place, the storage key that utilizes secret piece 3 is encrypted content key once more.

Fig. 3 is the block diagram of copyright non-conforming register 1B.The corresponding copyright non-conforming of register 1B storage card 40B.(among Fig. 3, those are endowed identical reference number with parts identical or of equal value shown in Figure 1 on function, and have omitted the description to it.)

For example, be designed to replace blattnerphone writes down oral account on storage card so-called IC sound-track engraving apparatus, be not subjected to usually such as consider the constraint of the copyright of meeting process.In this regard, voice data that is write down and copyright restrictions are irrelevant, can utilize record and the playback system that is made of register 1B and storage card 40B shown in Figure 3.

On directly perceived, register 1B has identical structure with the register 1A of Fig. 1, except that the latter's secret piece 3.Even (secret piece 3 is included, also only needs register is arranged to forbid that encryption function is to be used for the non-compatible purpose of copyright.)

Can comprise the microphone input on sound signal I/O part is directly perceived, or analog input and output.

If microphone is linked register 1B (if or wherein built-in microphone) to tap into sound signal by terminal 16, then sound signal is amplified by amplifier of microphone 17.The sound signal of amplifying converts digital audio-frequency data to by A/D converter 9, and it sends into encoder/decoder 7 by voice data interface 6.

If the audio output apparatus that simulated audio signal provides from the outside is supplied with register 1B, simulated audio signal is sent into A/D converter 9 to convert digital audio and video signals to by terminal 8.After the conversion, digital audio and video signals is sent into encoder/decoder 7 via voice data interface 6.

Encoder/decoder 7 is responsible for a digital audio and video signals of supplying with according to predetermined formula, and such as ATRAC3, ATRAC or ADPCM compress processing.So the data after the compression are admitted to CPU2.

Storage card 40B inserts register 1B in the mode that can freely separate.The storage card 40B register 1B that also can pack into.

CPU2 is by memory interface 11 and the storage card 40B swap data that is fixed on the separable mechanical hook-up (not shown).Memory interface 11 is guaranteed the serial data communication between CPU2 and the storage card 40B.

After encoder/decoder 7 compressions, voice data is sent into storage card 40B by memory interface 11 by CPU2.The voice data of delivering to storage card 40B is written into the flash memory 42 that is positioned at wherein.

The voice data of input is recorded among the storage card 40B via the above approach.When audio frequency and other data as above recorded among the storage card 40B of linkage record device 1B, data had been compressed but are not encrypted.The formula that is used to compress can be ATRAC3, promptly with register 1A in identical, also can be other suitable scheme such as ATRAC or ADPCM.

Voice data reproduces from storage card 40B as follows: CPU2 reads voice data by memory interface 11 from flash memory 42.By encoder/decoder 7 voice data that retrieves is decompressed out from its compressive state.

The decompression that encoder/decoder 7 is carried out produces 16 sample audio signal with the 44.1KHz sampling.This sound signal is sent into D/A converter 12 to convert simulated audio signal to by voice data interface 6.After the conversion, simulated audio signal outputs to external unit by terminal 13 or links the earphone of register.

Fig. 4 is the block diagram of the storage card 40B of no encryption function (being that this card does not have the security provisions about copyright).Among Fig. 4, those are endowed identical reference number at the parts identical or of equal value shown in Fig. 2 storage card 40A on function with, and have omitted the description to it.

With compare with reference to figure 2 described storage card 40A, storage card 40B illustrates no secret piece 52 and links serial/parallel and parallel/serial translation interface piece 43.Those of remaining structural function and storage card 40A are identical.

Although be not illustrated, the profile of storage card 40A and 40B is all identical with size.

As described, the present invention can carry out by realizing compatible register 1A of copyright and storage card 40A and copyright non-conforming register 1B and storage card 40B.

Compatible register 1A of copyright and storage card 40A are mainly used to write down and reproduce the data that require copyright protection, such as several songs.Copyright non-conforming register 1B and storage card 40B are used for writing down and reproducing the data that need not copyright protection, such as the meeting process.

Storage card 40A storage is by ATRAC3 compression and ciphered data in this way.On the other hand, storage card 40B contains by the compression of ATRAC3 or other formula, but not encrypted data.

Register 1A shown in Figure 1 does not have the security provisions about copyright.So, the storage card of register 1A and insertion each other interchange key with mutual mandate with carry out data encryption.

If copyright non-conforming storage card 40B inserts register 1A, register 1A judges that card 40B is unavailable because the latter and copyright protection require incompatible.

The method that the type of the definite storage card that inserts of a lot of register 1A is arranged.

A kind of method is that register 1A checks the responsive state to authorizing.

Particularly, when storage card inserted register 1A, the CPU2 of register 1A transmitted first authorization data to storage card in mode as mentioned above.If the card that inserts is the storage card 40B of no secret piece 52, CPU 2 can not receive normal response (promptly second authorization data) as mentioned above from card.

If CPU2 fails to obtain normal response within the schedule time after sending first authorization data, CPU2 judges that the storage card that inserts is a copyright non-conforming card.

The another kind of method of determining Card Type relate to copyright compatible/copyright non-conforming identifying information is stored in the suitable storage card boot section.

When storage card inserted register 1A, CPU2 was the data that read for the first time from the storage card boot section, and the retrieval copyright is compatible/copyright non-conforming identifying information.According to the identifying information of retrieval, register 1A determines the type (40A or 40B) of storage card.

Along with being determined of card type memory, register 1A only accepts the storage card 40A that licenses.This has just guaranteed that mandate and enciphered data go on record with the protection copyright.

As described, according to the copyright protection needs, register 1A should assemble storage card 40A and register 1B should assemble storage card 40B.Yet because storage card 40A and 40B were not only measure-alike but also outward appearance is identical, the user is difficult to difference and correct these two cards that use.Unsuitable combination-register 1A and storage card 40B combination or register 1B and storage card 40A combination between register and the card may often appear.

In case when storage card inserted any register, register 1A and 1B can overcome such problem by execution graph 5 and step shown in Figure 6.Be designed to from such as down-load music on the storage medium of CD or the internet as the register 1A of the mobile terminal device that is used to handle music; Be designed to write down voice as the register 1B of the mobile terminal device that is used to write down oral account from the microphone input.

Fig. 5 is the process flow diagram by the performed step of CPU2 of register 1A.

In step F 101, the CPU2 of the compatible register 1A of copyright checks whether storage card inserts.If find that storage card has inserted register 1A, then arrive step F 102.

In step F 102, CPU2 begins the storage card that inserts is carried out authorisation process.Specifically, CPU2 imports authorization data into storage card.

If licensing process has produced foregoing normal response, CPU2 judges that the card that inserts is for having the storage card 40A of secret piece 53 (copyright protection).If fail to obtain normal response in the given time, judge that the card that inserts is copyright non-conforming storage card 40B.

Before one of two steps below being branched off into, top deterministic process is carried out in step F 103 by CPU2.If the card that inserts is judged as the compatible storage card 40A of copyright, arrive step F 104.In step F 104, data are recorded in the storage card or reproduce (in fact, writing down or playback operation according to user's operation) from storage cards.

If the card that inserts is judged as copyright non-conforming storage card 40B, arrive step F 105, wherein CPU2 withdraws from storage card.

Above step prevents that register 1A from carrying out data recording or reproduction, if the user inserts register 1A to storage card 40B because of carelessness.Force and withdraw from storage card prompting user's operating mistake and point out it to insert correct storage card in addition.

Fig. 6 is the process flow diagram by the performed step of CPU2 of register 1B.

In step F 201, the CPU2 of copyright non-conforming register 1B checks whether storage card inserts.If find that storage card has inserted register 1B, arrive step F 202.
