DETAILED DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the present embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

FIG. 1 is a diagram illustrating an information recording medium 100 according to an example embodiment of the present invention. Such an information recording medium 100 can include a Blu-Ray Disc (BD), High Density Digital Versatile Disc (HD DVD), hybrid BD or HD DVD, or similar format. As shown in FIG. 1, the information recording medium 100 stores recorded data, such as audio/video (A/V) data or computer files, to be reproduced by a reproducing apparatus (not shown), such as a standalone BD player. The information recording medium 100 may contain additional types of data, such as navigation data for controlling A/V data. Alternatively, rather than storing data, the information recording medium 100 can be “blank” and capable of having data written to thereon by a consumer using a reading/writing apparatus (not shown). In an example embodiment of the present invention, the information recording medium 100 additionally contains information for software updating 110. By storing in the information recording medium 100 the information for software updating 110, it is possible to rapidly and effectively provide a user with a software update or information about a software update, and easily perform a software update on apparatuses capable of reproducing the data from the information recording medium 100.

The information for software updating 110 may be stored in an area of the information recording medium 100 that is normally accessible to the user. Additionally, aspects of the present invention allow the information for software updating 110 to be stored in an area of the information recording medium 100 the apparatus can access but that the user cannot normally access through normal operation. By storing the information for software updating 110 in an area of the information recording medium 100 that the user cannot normally access, the information for software updating 110 would not reduce the storage capacity of the information recording medium 100 from the amount that the user would normally expect (e.g., a “blank” 50 GB capacity BR-D containing a 1 GB update located in an area of the BR-D the user cannot normally access would still have a capacity to store 50 GB of data for the user). Additionally, by storing the information for software updating 110 in an area the user cannot normally access, the update can occur without requiring the involvement (or perhaps even the knowledge) of the user. Further still, proprietary or confidential data in files required for an update, but that the manufacturer does not wish the user to access, can be stored more safely in such an area.

The information for software updating 110 may be of several forms. According to one example embodiment of the present invention, information for software updating 110 can include information for software updating and the files required to perform the software update, so that the software in the reading apparatus can be updated directly by using the update files. Thus, when a user desires to reproduce data from an information recording medium 100, when a need to update the apparatus is determined, the update is performed prior to the data reproduction, thereby conveniently performing software updating and allowing the user to reproduce the data with the necessary update. Still further, aspects of the present invention provide that the software update can occur automatically without the user's involvement.

Alternatively, another aspect of the present invention provides that the information for software updating 110 can include only information for the user about a software updating and not all the files and data required for the update. In this situation, if a software update is needed, the user is informed of the required update, such as by an update message informing that an update is needed. The update message may contain an inquiry as to whether the user wants to directly access a network (not shown), via a networked apparatus, to download and perform the software updating, to allow the user to directly access the network (not shown) and perform the software update when he or she decides to directly perform software updating. Another alternative example embodiment of the present invention is that the information for software updating 110 may inform the user to contact a vendor for an upgrade kit, call a telephone number for instructions, or perform an action to complete an upgrade that requires activity by the user.

FIG. 2 is a schematic block diagram of an A/V data recording/reproducing apparatus according to an example embodiment of the present invention. Referring to FIG. 2, the apparatus, which records data on and reproduces data from an information recording medium (such as an information recording medium 100 shown in FIG. 1), includes an AV input unit 1 that receives an A/V signal; an audio analog-to-digital converter (ADC) 2 that converts an analog audio signal into a digital audio signal; a video ADC 3 that converts an analog video signal into a digital video signal; a memory 4 that stores a central processing unit (CPU) program for a backend; a volatile memory 5; a user interface 6, such as a remote control or keypad, via which a user input is received; an audio digital-to-analog converter (DAC) 7 that converts a digital audio signal into an analog audio signal; an A/V output unit 8 that outputs an A/V signal; a network controller 9 that controls a network access; a processor 10 that decodes MPEG data, performs graphic processing, and controls the overall operation of the apparatus; and a loader 20 that loads an information recording medium 100 (not shown) into the apparatus.

The memory 4 stores a program to be run by a CPU. The memory 4 may be a flash memory in which a read/write operation can be performed to change the stored program and thus allow a CPU program to be updated.

The loader 20 includes a CPU 21, which controls the overall operation of the loader 20; a memory 22, which stores a program for the CPU 21; a recording/reading unit 23, which reads data from and records data to the loaded information recording medium 100; and an interface 24, which provides an interface with a backend (not shown). Although not shown, the recording/reading unit 23 may include additional components, such as a pickup, a servo, a radio-frequency amplifier (RF-AMP), and a digital signal processor (DSP).

The processor 10 includes a CPU 11, which controls elements of the processor 10 and the overall system. The processor 10 may contain a graphic processor 12 to perform graphic processing for a graphic user interface, an MPEG encoder 13, and an MPEG decoder 14.

The CPU 11 reads program data from the memory 4, moves the read program data to the volatile memory 5, and then executes a related program, when the apparatus is booted, powered-on, or reset.

In particular, when an information recording medium 100 in which both AV data and information for software updating 110 are stored, is loaded into the apparatus (such as by inserting a HD-DVD), the CPU 11 according to an example embodiment of the present invention reads the information for software updating 110 from the information recording medium 100, determines whether software updating is needed, and performs an update by using the information for software updating 110 update files stored in the information recording medium 100 or outputs an update message containing information about the update when software updating is needed, prior to reproduction of the AN data. If the update message is output, if a user wants to update current software according to the update message, the user may access a website that provides update files, download desired update files, and perform updating, via the network controller 9. Also, the CPU 11 may control the A/V data to be reproduced when the user desires to reproduce it by using the current software without updating the current software. Additionally, the CPU 11 simply reproduces the A/V data from the information recording medium 100 when an update is not needed.

Software to be updated can include programs such as a CPU program for a backend, which is stored in the memory 4, or a CPU program for a loader 20, which is stored in the memory 22. Although it is not common, software to be updated may additionally be a program that the MPEG encoder 13 or the MPEG decoder 14 uses.

FIG. 3 is a flowchart illustrating a method of reproducing data to inform a user of a necessary update according to an example embodiment of the present invention. Referring to FIGS. 1 and 3, information for software updating 110 in an apparatus which reproduces data is read from the information recording medium 100 at block 310. The software may be a program executed by a CPU for a backend, a program executed by a CPU for a loader 20, a program executed by a CPU 11 for a processor 10, an MPEG encoder 13, an MPEG decoder 14, or similar software of the apparatus.

It is determined whether a software update is needed based on the read information for software updating 110, at block 320, when the information recording medium 100 is loaded in the apparatus. When the version of software in the information for software updating 110 is of a later release or higher revision than that of software installed in the apparatus, it is determined that a software update is needed.

If it is determined that a software update is needed, a message informing the user of the software update is output at block 330. If the message for software updating is included in the information for updating software 110 in the information recording medium 100, the message in the information for updating software 110 is used. Otherwise, a default update message set in the apparatus is used.

FIG. 4 is a block diagram of a file system of data stored in an information recording medium 100 according to an example embodiment of the present invention. Referring to FIGS. 1 and 4, the information recording medium 100 may store A/V data 410, navigation data 420 for controlling reproduction of the A/V data 410, and information for updating software 430 of a reproducing apparatus.

The information for software updating 430 contains a software update information file 431 that provides information regarding the software update. The content of an example software update information file 431 is shown in FIG. 5. Referring to FIG. 5, the software update information file 431 contains a software update information identifier 510, which identifies the software update information file 431 as a file that contains software update information, information regarding the number of update files 520, and plural pieces of update file information.

Each piece of the update file information may contain software type information 530, manufacturer name information 540, model name information 550, software version information 560, and an update message 570. The software type information 530 indicates which CPU can execute software of a corresponding update file. That is, the software type information 530 indicates whether the corresponding update file is software to be executed by a CPU for a loader 20, a CPU for a backend, or other blocks of a processor.

The update message 570 may contain information that provides users with detailed information about the software update. Alternatively, the update message 570 stored in an information recording medium 100 may contain only basic information for displaying a message such as a revision number or release date and use the default update message 570 stored on a reproducing apparatus. Thus, a reproducing apparatus may combine the basic information with other information and displays the result of the combination as the message to the user.

The following content may be included into the update message 570, as shown in FIG. 8.

1) The release date of an update file: The update message 570 shown in FIG. 8 may contain a sentence, for example, “This title requires software update released Jun. 3, 2006” regarding the release date of an update file.

2) Problems that may occur unless updating is performed: The update message 570 shown in FIG. 8 may contain a sentence, for example, “Black dots may appear during playback unless a software update is performed” regarding a problem that may occur if the update is not performed.

3) An updating method, e.g., the name of a website from which update files can be downloaded, and (on networked apparatuses) an inquiry as to whether a user desires to access the website to immediately perform the update: The update message 570 shown in FIG. 8 may contain a sentence, for example, “Download the desired update files by accessing website at www.xxxx?” and selections of “Yes” or “No”.

4) An inquiry as to whether the user wishes to continue without performing the update: The update message 570 shown in FIG. 8 may contain the sentence, for example, “Continue without updating software?” and provide the user with selections of “Yes” or “No”.

FIG. 6 is a flowchart illustrating a method of reading data according to another example embodiment of the present invention. Referring to FIGS. 1 and 6, when a user loads an information recording medium 100 according to an example embodiment of the present invention into a reproducing apparatus in order to reproduce data from the information recording medium 100, a CPU of the reproducing apparatus reads update file information from the information recording medium 100 before reproduction of the stored data at block 610.

Then, the CPU analyzes the read update file information at block 620. That is, the CPU searches the read update file information for update file information that matches the specifications of the reproducing apparatus. For example, referring to FIG. 7, when software type is “software for a CPU for backend”, the manufacturing company's name is “Samsung”, and the model name is “SAM 1”, an apparatus matching those specifications would search the update file information for the above particulars.

Next, the CPU determines whether an update is needed at block 630. That is, the CPU compares the version and release date of the software that the reproducing apparatus is currently using, with version and release date information specified in the update file information and determines that an update is needed when the version reported in the information for software updating 110 was released later or is of a higher number version than the version of the software installed in the reproducing apparatus. Otherwise, the apparatus determines that an update is not needed. For example, as shown in FIG. 7, when the information for software updating 110 has a software version specified in update file information of 2.0 and the version of software in a reproducing apparatus is 1.0, the apparatus determines that a software update is needed. If a software update is not needed, the CPU controls the reproducing apparatus to reproduce the data from the information recording medium at block 680.

If software update is needed, the apparatus outputs an update message at block 640. If an update message is included in the information for updating software 110 in the information recording medium 100, the update message is output. Otherwise, if a message is to be output but no specific message is included on the information reproducing medium 100, a default update message set in the reproducing apparatus is output. An example of an update message is shown in FIG. 8 and discussed above.

For those apparatuses that are networked, it is determined whether a user wishes to access a network so as to perform the software update at block 650. This is the third item of the update message shown in FIG. 8 and described above. If the user wishes to update via a network, such as when the user selects “Yes” in the third item of the update message shown in FIG. 8, the software update is performed by accessing a website that provides update files, via the network controller 9, as shown in FIG. 2, at block 660, and the data is reproduced from the information recording medium 100 at block 680.

If the user does not wish to update the software, such as when the user selects “No” in the third item of the update message shown in FIG. 8, it is then determined whether the user wishes to read the data by using the existing software without updating the software at block 670.

If the user wishes to reproduce the data without updating the software, such as, when the user selects “Yes” in the fourth item of the update message shown in FIG. 8, the data is reproduced from the information recording medium 100 at block 680. If the user does not wish to reproduce the data without updating the software, such as, when the user selects “No” icon, the update message shown in FIG. 8, the apparatus is shut down, put in a default state, or the apparatus does some other action to end the method of reproducing data from the information recording medium 100.

FIG. 9 is a block diagram of a file system of data stored in an information recording medium 100 (of FIG. 1) according to another example embodiment of the present invention, wherein all the files required to perform the update are included on the information recording medium. Referring to FIG. 9, the information recording medium 100 can store a variety of type of data (e.g. document files, photos, and computer programs) and, in the present exemplary embodiment, A/V data 910, navigation data 920 for controlling reproduction of the A/V data 910, and data 930 for updating software executed in a reproducing apparatus (similar to the information for software updating 110 shown in FIG. 1).

The data 930 includes a software update information file 931 that provides information regarding software updating, and may contain additional update files 932, . . . , 933. FIG. 10 illustrates the content of the software update information file 931 shown in FIG. 9 according to an example embodiment of the present invention.

Referring to FIG. 10, the software update information file 931 includes a software update information identifier 1010 that identifies the software update information file 931 as a file that provides software update information, information 1020 regarding the number of update files 1020, and plural pieces of update file information. Each piece of update file information includes software type information 1030, manufacturer name information 1040, model name information 1050, software version information 1060, update file name information 1070, and update message 1080.

The software type information 1030, the manufacture name information 1040, the model name information 1050, and the software version information 1060 are as described above with reference to FIG. 5. The update file name information 1070 provides the names of the update files 932, . . . , 933, the files that contain the data to update the apparatus. A manufacturer or vendor may wish to update the software of an apparatus without requiring the involvement of a user, or the manufacturer or vendor may wish to inform the user of the update. The update message 1080 may contain information to be displayed to the user similar to FIG. 8 and discussed above, informing of the user of the update, the update version, and if any action by the user is required to perform the update. Alternatively, the update message 1080 may contain data that instructs the apparatus to perform the update without involving or informing the user, and therefore no message would be displayed.

FIG. 11 is a flowchart illustrating a method of reproducing data from an information recording medium according to another example embodiment of the present invention. Referring to FIG. 11, when a user loads an information recording medium 100 into a reproducing apparatus in order to reproduce data from the information recording medium 100, a CPU of the reproducing apparatus-analyzes the type of the information recording medium 100, and reads update file information from the information recording medium 100 prior to data reproduction at block 1110.

The CPU interprets the read update file information at block 1120, and searches for update file information matches the type (manufacturer and model number) of the reproducing apparatus. The CPU determines whether a software update is needed according to the analysis at block 1130. Specifically, the CPU compares the version of software currently installed in a reproducing apparatus with the version information specified in the update file information, and determines that software update is needed when the version information specified in the update file information is later in time or higher in revision than the version of the software installed in the reproducing apparatus, and otherwise determines that a software update is not needed.

If software update is not needed, the CPU controls the reproducing apparatus to reproduce the data from the information recording medium 100 at block 1160. However, if software update is needed, the CPU performs the software update by using the update files included in the data 930 (shown in FIG. 9) for software updating, which is read from the information recording medium 100 at block 1140. For example, the CPU may, by using the update files in the data 930 for software updating, update a program for a CPU for backend, in a flash memory that stores the program for the CPU for backend; and update a program for a CPU for the loader in a flash memory that stores the program for the CPU for loader.

After performing software updating, the CPU initializes the reproducing apparatus at block 1150, and proceeds to block 1110 again. This allows for successive software updates to be performed, if required.

The above example embodiments of a method of reproducing data according to the present invention are applicable to various types of information recording medium reproducing apparatuses, including a standalone DVD player, CD player, DVD-R read/writer, and other apparatuses that can read from an information recording medium.

The above example embodiments of a method of reproducing data according to the present invention can be embodied as computer readable code in a computer readable medium. Here, the computer readable medium may be any recording medium capable of storing data that is read by a computer system, e.g., a read-only memory (ROM), a random access memory (RAM), a compact disc (CD)-ROM, a magnetic tape, a floppy disk, an optical data storage device, and so on.

As described above, according to the present invention, when a user desires to reproduce data from a specific information recording medium, it is determined whether updating of software in an reproducing apparatus is needed, and an update is performed using update files stored in the information recording medium, or a message informing the user that an update is needed is provided, if necessary. Accordingly, the user can easily receive update information and perform a software update, and a manufacturer who manufactures reading apparatuses can effectively provide the user with software updates and software update information.
