Description

  The present invention relates to a recording medium compatible with, for example, BD-J (Blu-ray Disc Java (registered trademark)) and an information processing apparatus that executes processing such as reproduction processing of content recorded on the recording medium.

  BD-J is a platform for interactive content in BD (Blu-ray Disc). On a BD-J compatible disc, an application program (software program) based on Java (registered trademark) technology is recorded together with content data (video data, audio data, etc.) such as a movie.

  According to BD-J, using a recorded application program, a predetermined URL (Uniform Resource Locator) is accessed through a network to download the latest trailer, implement a picture-in-picture function, A non-patent document 1 and a non-patent document 2).

The above non-patent documents are as follows.
Free encyclopedia “Wikipedia” Blu-ray Disc Association (http://www.blu-raydisc.com/)

  By the way, according to the standard, the BD-J has a function called “Virtual Package”. This is a technology that realizes data appending by virtually merging the contents of storage such as an optical disk and a hard disk provided in an information processing apparatus that processes the recording information of the optical disk.

  In this case, according to the standard, data additional writing is performed only on a hard disk or the like provided in the information processing apparatus, and the additional recording data cannot be written on a BD-J compatible optical disc. For this reason, when the optical disk is ejected from the information processing apparatus, the added data remains only on the hard disk of the information processing apparatus and is not held on the optical disk.

  Therefore, when the optical disk is loaded into another information processing apparatus, the additionally recorded data cannot be accessed, and there is a problem that the additionally recorded data appears to be lost to the user.

  In addition, even in the case of realizing the network cooperation as described above using BD-J, connection destination information and authentication information through the network cannot be managed together with the optical disc. And the need to specify information for authentication.

  An object of this invention is to provide the recording medium which solved the above problem, and the information processing apparatus with which the said recording medium is loaded.

In order to solve the above problems, the present invention provides:
A recording area for recording content data and at least information of a software program for processing the content data, and an access method for reading and writing data used during execution of the software program Provides a recording medium provided with memory means that can be accessed by a different access method from the recording area.

  When the recording medium according to the present invention is applied to, for example, an optical disc compatible with BD-J, data added by execution of the software program is also retained in the memory means of the recording medium and remains on the recording medium. Therefore, even if the recording medium is loaded into another information processing apparatus, it becomes possible to access the additional write data.

  According to the present invention, additional data, setting data, and history data can be held in the memory means of the recording medium. Therefore, even when the recording medium is loaded in another information processing apparatus, these memories are stored. Software program processing using data held in the means is possible.

  Hereinafter, embodiments of a recording medium and an information processing apparatus according to the present invention will be described with reference to the drawings. In all of the embodiments described below, the recording medium is a BD-J compatible optical disc.

[First embodiment of information processing apparatus]
FIG. 2 is a block diagram of the first embodiment of the information processing apparatus according to the present invention. The information processing apparatus 10 according to the first embodiment has a function of reading content data and an application program recorded on the optical disc 1 which is an embodiment of the recording medium according to the present invention described above, and data stored in the IC chip 4. And a function of writing data to the IC chip.

  The information processing apparatus 10 of this embodiment includes a loading unit (not shown) for the optical disc 1. FIG. 2 shows a state in which the optical disc 1 is loaded in the loading unit. In a state where the optical disk 1 is loaded in the loading unit, the optical disk 1 is fixed to the rotating shaft 12 of the spindle motor 11 by a chuck mechanism (not shown) and is driven to rotate by the spindle motor 11. The spindle motor 11 is speed-controlled by a spindle servo circuit 13 that receives a control signal from the system controller 20.

  The system controller 20 is for controlling the entire information processing apparatus 10 of the embodiment, and in this example, is configured by a microcomputer.

  Connected to the system controller 20 is an input operation unit 14 including operation buttons for playback control of the optical disc 1 such as a playback start button and a stop button, and operation buttons for inputting a URL, a password, and the like. The input operation unit 14 may be configured as a remote control device including a transmission unit and a reception unit that exchange remote control signals using infrared rays, for example.

  Further, as a local storage, in this example, a hard disk device 15 is connected to the system controller 20. Further, in this example, the system controller 20 is connected to a communication interface 16 for connecting to a network such as the Internet. The communication interface 16 is connected to a telephone line or an optical cable.

  The information processing apparatus 10 according to this embodiment includes an optical pickup 21 for reading data recorded in the information recording area of the optical disc 1. The optical pickup 21 can be moved in the radial direction of the optical disk 1 by a thread mechanism 22. The sled mechanism 22 receives servo control from the sled servo circuit 23 that has received the reproduction position control signal from the system controller 20, and is controlled so that the optical pickup 21 accesses the designated reproduction position on the optical disc 1.

  Information read from the information recording area 3 of the optical disc 1 by the optical pickup 21 is supplied to the reproduction circuit 24.

  When the information read from the information recording area 3 of the optical disc 1 is content data (video and audio data), it is supplied to the demodulation circuit 25, demodulated, and supplied to the AV processing unit 26. From the AV processing unit 26, a video signal output terminal and an audio signal output terminal are derived. Through the video signal output terminal and the audio signal output terminal, the video signal and the audio signal are supplied from the AV processing unit 26 to, for example, a reproduction monitor device (not shown) including a display for display and a speaker.

  When the information read from the information recording area 3 of the optical disc 1 is an application program, it is cached in the memory of the system controller 20 or temporarily held in, for example, the hard disk device 15. Then, the application program is executed by the system controller 20.

  The information processing apparatus 10 according to this embodiment further includes a data read / write unit 27 for reading and writing data stored in the memory of the IC chip 4 of the optical disc 1. Although not shown, the data read / write unit 27 includes a coil unit that is electromagnetically coupled to the coil unit 5 of the optical disc 1 and reads / writes data from / to the IC chip 4.

  In this embodiment, when the BD-J compatible optical disc 1 is loaded into the information processing apparatus 10, the data read / write unit 27 reads the data if the IC chip 4 is stored, and the system controller 20. In the work area memory. The data held in the memory in the work area is used when the application read from the optical disc 1 is executed.

  In this case, the data read / write unit 27 can read the data of the IC chip 4 in accordance with the application program recorded on the optical disc 1, or the data read from the IC chip 4 when the optical disc 1 is loaded. It can also be configured to always execute the reading.

  That is, in the former case, the application program recorded on the optical disc 1 includes a processing procedure for reading data written in the IC chip and using it for processing. Then, the read / write unit 27 reads data from the IC chip 4 through the system controller 20 according to the processing procedure of the application program.

  In the latter case, when the optical disk 1 is loaded, the read / write unit 27 reads data from the IC chip 4 according to the control of the system controller 20 and passes the read data to the system controller 20. . The system controller 20 holds the read data in the work area memory. In this case, the application program recorded on the optical disc 1 includes a processing procedure for accessing data in the memory in the work area of the system controller 20. The latter is a case where the above-described “Virtual Package” function is used.

  Further, when data to be recorded on the optical disc 1 is generated by executing the application program recorded on the optical disc 1, in this embodiment, the data held in the memory of the system controller 20 is stored in the application program. The processing procedure for writing to the IC chip 4 is included.

[Application example]
<First example: Network access>
In this example, when content recorded on the optical disc 1 is reproduced, a predetermined server is accessed to acquire predetermined information from the server, and the acquired predetermined information is reflected in the reproduction of the content. This is the case of the application to make.

  In this example, when the optical disk 1 is used to access the server, the IC chip 4 does not store data necessary for network access such as the server URL, password, and user ID. Enter those data settings. However, when data necessary for the network access is stored in the IC chip 4, the data stored in the IC chip 4 is used, and a user input operation is not necessary.

  However, in this example, a simple password is used in consideration of the case where authentication of a specific password is required in order to specify a part of users instead of opening server access to all users. Secure access is possible. That is, in this embodiment, a specific password necessary for authentication in the server is used as the main password, and a simple password for permitting use of the main password is used.

  The main password stored in the IC chip 4 is not automatically read out, but is read out from the IC chip 4 only when the simple password input by the user is the correct simple password. Thus, access to the server using the password is permitted.

  FIG. 3 shows an example of data necessary for network access stored in the IC chip 4 in the case of this example. In this example, as shown in FIG. 3, as data necessary for network access, a user identifier (user ID), a main password, a simple password, and a server URL are used. Here, this password has a relatively large number of digits such as 8 digits or more, and the simple password can have a relatively small number of digits such as 4 digits or less.

  These data are initially set and input by the user, and when the user inputs a setting, the setting input data is written to the IC chip 4 of the optical disc 1.

  That is, the information processing apparatus 10 according to this embodiment checks whether data necessary for network access is stored in the IC chip 4 when the optical disk 1 is loaded. Then, if the data is not stored in the IC chip 4, the information processing apparatus 10 causes the user to input the data. Further, if the data necessary for network access is stored in the IC chip 4, the information processing apparatus 10 performs network access using the stored data. It should be noted that the processing for checking the presence or absence of data stored in the IC chip 4 and the network access performed by the information processing apparatus 10 is performed according to the application program recorded on the optical disc 1.

  FIG. 4 and FIG. 5 show examples of flowcharts of the processing flow when the application program recorded on the optical disc 1 includes a network access procedure. When the optical disk 1 is loaded into the information processing apparatus 10, the system controller 20 of the information processing apparatus 10 reads the application program from the optical disk 1. Then, the system controller 20 starts executing the application program and starts processing from the start of FIG.

  First, the system controller 20 performs a process of reading data from the IC chip 4 in accordance with an application program read from the optical disc 1 (step S101). Then, it is determined whether or not data necessary for network access is stored in the IC chip 4 (step S102).

  In step S102, when it is determined that the data necessary for network access is not stored in the IC chip 4, the system controller 20 generates an input screen and audio information for prompting the user to input, It is sent to the playback monitor device through the AV processing unit 26 (step S103). In the playback monitor device, an input screen for inputting data settings necessary for network access is displayed on the display screen, and a voice message for prompting input of data settings necessary for network access is emitted from the speaker. .

  The user receives the input screen and the voice message and inputs the data setting necessary for the network access described with reference to FIG. 3. Therefore, the system controller 20 receives the setting input and receives the memory (in the work area ( Buffer). Then, the system controller 20 executes network access to the server using the data that has been set and input (step S104).

  Next, the system controller 20 determines whether or not the server can be normally accessed (step S105). When it is determined that the access has not been made normally, the system controller 20 generates display screen information and audio information for notifying the user that an error has occurred, and reproduces the display screen information and audio information through the AV processing unit 26. To notify the user of the error (step S106). Then, the process returns to step S103, and the user is again prompted to input data settings.

  If it is determined in step S105 that the server has been successfully accessed, the system controller 20 processes the content data recorded on the optical disc 1 using information acquired from the server. Thus, processing according to the application program is executed (step S107).

  Then, the system controller 20 waits for an application program termination instruction from the user (step S108), and when determining that the termination instruction has been received, the system controller 20 stores the data set and input by the user held by the optical disc. 1 is written to one IC chip 4 (step S109). Thereafter, the application program ends.

  In step S102, when it is determined that data for network access is stored in the IC chip 4 of the optical disc 1, the system controller 20 prompts the user to input a simple password and an audio. Is sent to the reproduction monitor apparatus through the AV processing unit 26 (step S201). Therefore, in the reproduction monitor device, an input screen for inputting a simple password setting is displayed on the display screen, and a voice message for prompting input of the simple password setting is emitted from the speaker.

  The user receives the input screen and the voice message and inputs a simple password. The system controller 20 receives the input and holds it in the memory (buffer) of the work area. Then, the system controller 20 compares the input simple password with the simple password stored in the IC chip 4 and confirms whether the two match, thereby determining whether the input simple password is correct. It discriminate | determines (step S202).

  When it is determined in step S202 that the input simple password is not correct, the system controller 20 determines whether or not the input error of the simple password is, for example, the third time (step S203). The number of incorrect input of the simple password may be set to 4 times or more instead of 3.

  If it is determined in step S203 that the number of incorrect input passwords of the simple password is less than 3, the process returns to step S201 to accept another simple password input. If it is determined in step S203 that the number of erroneous input of the simple password is the third, the data for network access stored in the IC chip 4 of the optical disc 1 is erased (step S204). Thereafter, the process jumps to step S106, and the processes after step S106 are performed.

  When it is determined in step S202 that the input simple password is correct, the system controller 20 executes network access to the server using the data stored in the IC chip 4 read in step S101 ( Step S205).

  Then, it is determined whether or not normal access is possible (step S206), and when it is determined that normal access cannot be performed, the process jumps to step S106 to perform the processing after step S106.

  When it is determined in step S206 that the access has been made normally, the system controller 20 performs processing using the information acquired from the server for the content data recorded on the optical disc 1. Then, the process according to the application program is executed (step S207).

  Then, the system controller 20 waits for an application program termination instruction from the user (step S208), and when determining that there is an termination instruction, the system controller 20 terminates the execution of the application program read from the optical disc 1.

  As described above, in this embodiment, first, the user needs to set and input data for network access. However, in step S109, the data is stored in the IC chip 4 of the optical disc 1 and stored. Is done. Therefore, after that, if the information processing apparatus has a configuration equivalent to that of the information processing apparatus 10, the user does not need to input data settings. However, in the above-described embodiment, the user needs to input a simple password.

  By holding the data used for network access in this example in the IC chip 4, the following applications can be realized.

  That is, when a private photograph or video is stored on the optical disc 1, not only the content on the optical disc 1 but also the content in the network storage is taken out and a viewer (Viewer) that can be integrated and displayed is created. An address (URL) and a user ID are recorded on the IC chip 4.

  When the optical disc 1 is lent to a friend and played on another information processing apparatus, the friend can use the content only by loading the optical disc 1 and operating the viewer. In the case where a simple password is used as in the above-described embodiment, it is not necessary to teach the friend only to teach the simple password. In order to strengthen security, a multi-digit password is often used. However, it is not necessary to notify the friend of the multi-digit password, and only a simple password needs to be notified, so input errors are reduced.

<Second example: Resume playback>
In this second example, the previous reproduction stop position information of the content recorded on the optical disc 1 is stored and held in the IC chip 4, and in the next reproduction, the previous reproduction stop position stored and held. This is the case of an application that starts playback from the beginning. Such reproduction is called resume reproduction.

  According to this example, since the previous playback stop position of the content is held in the IC chip 4, resume playback is possible even if the information processing apparatus is different from the previous playback time. For example, the continuation of the movie content on the optical disc 1 that was being watched in the living room can be continuously watched by changing the place to a bedroom.

  FIG. 6 shows an example of a flowchart of the resume playback processing flow when an application program for realizing resume playback is recorded on the optical disc 1. When the optical disk 1 is loaded into the information processing apparatus 10, the system controller 20 of the information processing apparatus 10 reads the resume reproduction application program from the optical disk 1. Then, the system controller 20 starts executing the software program and starts processing from the start of FIG.

  First, the system controller 20 performs a process of reading data from the IC chip 4 in accordance with an application program read from the optical disc 1 (step S301). Then, it is determined whether or not the previous reproduction stop position data is stored in the IC chip 4 (step S302).

  In step S302, when it is determined that the data of the previous reproduction stop position is stored in the IC chip 4, the system controller 20 displays the display image information of the message screen for confirming whether or not the user performs resume reproduction. Then, the audio information is generated and sent to the reproduction monitor apparatus through the AV processing unit 26 (step S303). In the reproduction monitor device, a message screen for confirming whether or not resume reproduction is performed is displayed on the display screen, and a voice message for prompting confirmation input is emitted from the speaker.

  The user receives the confirmation screen and the voice message, and performs a confirmation input as to whether or not to resume playback. Therefore, the system controller 20 accepts the confirmation input and determines whether or not the resume reproduction is performed ( Step S304).

  When it is determined that resume playback is to be performed, the system controller 20 waits for a playback start instruction operation from the user (step S305), and when it is determined that a playback start instruction operation has been performed, resume playback is performed. That is, the system controller 20 starts playback of the content recorded on the optical disc 1 from the playback position designated by the previous playback stop position data (resume point data) read from the IC chip 4 (step). S306).

  Then, the system controller 20 monitors the playback stop instruction operation by the user (step S307). When it is determined that the playback stop instruction operation has been performed, the system controller 20 stops the playback of the content, and holds the data of the stopped playback position ( Step S308).

  Next, the system controller 20 determines whether or not the user has performed an eject instruction operation on the optical disc 1 (step S309). If it is determined that the eject instruction operation has not been performed, the system controller 20 determines whether or not the reproduction restart instruction operation has been performed (step S311). If the reproduction restart instruction operation has not been performed, the system controller 20 proceeds to step S309. Return.

  If it is determined in step S311 that an instruction to restart playback has been made, the system controller 20 restarts playback of the content from the playback position stopped in step S308 (step S312).

  When it is determined in step S309 that the optical disc 1 has been ejected, the system controller 20 writes the data of the final stop reproduction position immediately before the ejection that is held in the IC chip 4 (step S310), and then resumes. The playback processing routine ends.

  If it is determined in step S302 that the previous reproduction stop position data has not been stored in the IC chip 4, the system controller 20 waits for a reproduction start instruction operation (step S313), and the reproduction start instruction operation is performed. Sometimes, the content of the optical disc 1 is reproduced from the beginning (step S314). And after that, it progresses to step S307 and repeats the process after the said step S307.

In the information processing apparatus 10 according to the first embodiment described above, the information processing apparatus 10 includes the data read / write unit 27 that reads / writes data from / to the IC chip 4 of the optical disc 1.

  On the other hand, as shown in FIG. 7, in the information processing apparatus 30 of the second embodiment, an apparatus unit that reads and writes data from and to the IC chip 4 of the optical disc 1 is externally attached to the information processing apparatus body 31. The data read / write device 32 of FIG. A general-purpose interface such as USB (Universal Serial Bus) can be used as an external interface. FIG. 7 shows a state in which the information processing apparatus main body 31 and the data read / write apparatus 32 are connected using the USB cable 33.

  FIG. 8 is a block diagram illustrating an example of the overall configuration of the information processing apparatus 30 according to the second embodiment. In FIG. 8, the same parts as those of the information processing apparatus 10 of the first embodiment are denoted by the same reference numerals.

  As is clear from a comparison between FIG. 8 and FIG. 2, the information processing apparatus main body 31 of the second embodiment includes the built-in data read / write unit 27 and the external device interface 34. Different from the information processing apparatus 10 of the first embodiment. The other configuration of the information processing apparatus main body 31 of the second embodiment is exactly the same as that of the information processing apparatus 10 of the first embodiment.

  In this example, the external device interface 34 is a USB interface and is connected to the data read / write device 32 through the USB cable 33.

  In the second embodiment, the user holds the optical disk 1 over the non-contact data read / write unit 32a of the data read / write device 32 before loading the information processing device main body 31 with the IC chip 4 on the data read / write device 32. The data is read out.

  The data read / write device 32 transfers the data read from the IC chip 4 to the system controller 20 of the information processing device main body 31 through the USB interface 34. The system controller 20 writes the transferred data in a predetermined memory area (virtual package area) of the hard disk device 15.

  In the case of the second embodiment, the data read from the IC chip 4 is stored in the application program recorded on the optical disc 1 when the data stored in the IC chip 4 is used.

  Therefore, in the case of the second embodiment, when data is written to the IC chip 4, the application program recorded on the optical disc 1 does not end the processing routine even if the optical disc 1 is ejected. A processing procedure for writing to the later IC chip 4 is included.

  That is, after the ejection of the optical disk 1, when the user holds the data read / write device 32, the data stored in the hard disk device 15 is supplied to the data read / write device 32 through the external device interface 34 and written to the IC chip 4. . This processing procedure is included in the application program recorded on the optical disc 1.

  In the second embodiment, data read / write access to the IC chip 4 is different from that of the first embodiment, and is recorded on the optical disc 1 in the same manner as in the first embodiment. Content and application programs are executed.

  According to the second embodiment, the information processing apparatus 30 does not need to incorporate the data read / write unit 27 that reads / writes data from / to the IC chip 4 of the optical disc 1. There is an advantage that it can be used as it is.

  In the second embodiment described above, data to be read from and written to the IC chip 4 is routed through the hard disk device 15 of the information processing apparatus 31. However, the IC chip 4 is not transmitted through the heap memory but the hard disk device. You may make it provide the mechanism which reads and writes with respect to.
