Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for supporting recording and reproduction on a removable disk of two or more different data formats with one apparatus.
[0002]
[Prior art]
Digital recorders that digitally record AV data transmitted by digital broadcasting have been developed and sold. A digital recorder is generally used by being connected to a digital television (hereinafter referred to as “DTV”) or the like that receives a digital broadcast through an IEEE 1394 interface. IEEE 1394 enables inter-device transfer of AV data or the like that requires real-time performance by an isochronous transfer method, and enables transfer of data related to control between devices by asynchronous transfer. For the transfer of data relating to this control, AV / C commands defined by 1394 Trade Association are used.
[0003]
The AV / C command is a command set for remotely controlling another AV device to which the AV device is connected by IEEE1394. Here, a remote control side, that is, a device that transmits a command, such as a DTV, is referred to as a controller, and a remote control side, that is, a device that receives a command, such as a digital recorder, is referred to as a target. The commands include commands for controlling the functions of the target such as playback, recording, and writing / reading of information regarding AV data, and commands for inquiring about the state of the target.
[0004]
Various applications are realized using this AV / C command. For example, the DTV uses AV / C commands to read information such as the title name, recording date and time, and program contents regarding each AV data from the digital recorder so that the user can select AV data with reference to the information. It is an application that shapes them and displays them on the display, and when one of the displayed information is selected and operated by the user, an AV / C command for reproducing AV data corresponding to the information is transmitted to the digital recorder. .
[0005]
Hereinafter, an example of the flow of processing for this application will be described.
The DTV receives AV data transmitted through digital broadcasting, and information related to AV data such as a title name, recording date and time, and program contents from an EPG (electronic program guide) transmitted together (hereinafter referred to as AV data information). )) And transfer them to the digital recorder using an AV / C command instructing their writing.
[0006]
The digital recorder that has received the AV / C command records the transferred AV data and AV data information on a recording medium in accordance with the instruction of the AV / C command.
Subsequently, after the recording is completed, the DTV instructs the digital recorder using an AV / C command that instructs reading so that all AV data information held by the digital recorder in the recording medium is read from the recording medium. .
[0007]
Upon receiving this command, the digital recorder transmits AV data information related to the read instruction to the DTV.
The DTV that has acquired the AV data information creates a list listing title names, program contents, and the like based on the information, and displays the list on the display.
When one piece of information in the list is selected by a user operation, the DTV specifies AV data corresponding to the selected information, instructs the digital recorder to read the AV data, and as a result, the AV to be transferred Play the data on the display.
[0008]
By the way, when the recording target medium of the digital recorder is an optical disc, the data format differs depending on the type of the optical disc, and therefore there is a compatibility problem depending on the combination of the device and the optical disc.
Here, the data format defines the type, area, and area size of AV data information recorded on the optical disc. For example, in the case of DVD-RAM and DVD-RW, a video coding format is applied as the data format, and in the case of DVD-R and DVD-ROM, the DVD video format is applied.
[0009]
In order to cope with this compatibility problem, there is a conventional technique that analyzes the file structure and contents of an optical disc and performs a reproduction process based on the analysis result (see, for example, Patent Document 1).
[0010]
[Patent Document 1]
Japanese Patent Laid-Open No. 2001-57026
[0011]
[Problems to be solved by the invention]
However, if the corresponding data formats of the DTV and the optical disk mounted on the digital recorder are different, and the information defined in the DTV data format is not defined in the data format of the optical disk, the DTV uses the AV / C command. There is a problem that the digital decoder cannot write the information instructed to record on the optical disc, and this problem cannot be solved by the technique of Patent Document 1. As a result of being unable to write, even if the DTV instructs the digital recorder to read out the information, the DTV cannot obtain the information because it is not recorded on the optical disc, and cannot be displayed on the display. Occur.
[0012]
In particular, since the data format corresponding to a large-capacity optical disk developed in recent years defines a variety of data that does not exist in the current format, the above-mentioned compatibility problem between the device corresponding to this optical disk and the current optical disk Becomes prominent. As a solution to this, a method in which the DTV identifies the format of the optical disk mounted on the digital recorder and switches the AV / C command to be issued to the digital recorder according to the identification result can be considered. However, this method has a problem that the development efficiency of the application on the DTV side is inferior.
[0013]
Therefore, an object of the present invention is to provide a digital recorder that solves the above-described compatibility problem without requiring a controller such as a DTV to switch commands according to the data format of an optical disc mounted on the digital recorder.
[0014]

[0028]
Although not shown, the data format of the optical disk 372 defines not only the recorded program management information 500 but also an AV data area.
The data format of the optical disc 372 shown in FIG. 4 defines the recording date / time data 550 and title data 560 for the recording date / time data 440 and title data 450 of FIG. The information data 460 is not defined. That is, this digital format allows recording date / time data and title data to be recorded on the optical disc 372, but does not allow content information data to be recorded.
[0029]
It should be noted that the data format of the optical disc allows data recording of which data type and does not allow data recording of which data type is limited to the example of FIG.

That is, the recording date / time data 440 and the title data 450 which are constituent elements of the program individual information # 1 in FIG. 3 are the same as the recording date / time data 550 and the title data 560 which are the constituent elements of the program individual information # 1 in FIG. It is. Further, the content information data 460 that is a component of the program individual information # 1 in FIG. 3 is the same data as the content information data 620 that is a component of the program individual information # 1 in FIG.
[0031]
Next, recording of AV data information will be described.
FIG. 6 shows an FCP framework transmitted from the DTV 110 to the optical disc recorder 120.
FCP is a protocol for controlling AV equipment on IEEE1394 used in AV / C commands.
[0032]
FIG. 7 shows the data structure of an AV / C command indicating a recording instruction.
In the figure, an AV / C command stores an operation code 800 indicating instruction content (data write), auxiliary information 810 indicating capture information regarding the instruction content, a transfer length 820 indicating the size of data to be transmitted, and data. An address 830 indicating a position, an original data length 840 indicating the length of data to be overwritten, and data 850 storing data to be transmitted (in this case, AV data information).
[0033]
The AV / C command of FIG. 7 is stored in the FCP command storage area 700 of FIG. 6 and transferred.
Next, how the recording instruction command for the AV data information transferred using the data structure shown in FIGS. 6 and 7 is processed in the optical disc recorder 120 will be described.
[0034]
FIG. 8 is a flowchart showing AV data information recording processing in the optical disc recorder 120.
The AV / C command and AV data information transmitted from the DTV 110 are received through the asynchronous processing means 320 (step 900).
The command processing means 330 takes out the AV / C command from the command storage area 700, interprets the operation code 800, etc., and determines the processing content. Next, the command processing means 330 takes out the AV data information and determines whether there is an area that can be recorded on the optical disk for each of the data stored in the program individual information 420 (step 901). This determination is performed by detecting a data type that is allowed to be recorded in a predetermined data format on the optical disc, and comparing the detected data type with the data type stored in the program individual information 420. Is called.
[0035]
More specifically, the command processing unit 330 specifies what the data format of the optical disc is. Specifically, for example, the command processing means 330 stores in advance the characteristics unique to each data format in correspondence with the name of the data format, and examines what characteristics the mounted optical disc has. Specified.
[0036]
As features, for example, data unique to each data format, data length unique to each data format, structure unique to an optical disk of each data format, data format name recorded in each data format, and the like can be used.
Next, the command processing means 330 detects a data type whose data format permits recording. More specifically, the command processing unit 330 stores in advance each data format and the name of the data type that the data format allows recording, and stores the data type corresponding to the specified data format. The name is detected by reading from the stored contents.
[0037]
Finally, the command processing means 330 acquires the data type of the program individual information 420 and determines whether or not each acquired data type matches the previously detected data type. As a result of this determination, the matching data type is allowed to be recorded on the optical disc, and the non-matching data type is not allowed to be recorded.
As a result of the determination in step 901, data having an area to be stored on the optical disc, for example, recording date / time data (Yes in step 901) is recorded on the optical disc 372 via the optical disc drive control means 360 (step 902).
[0038]
On the other hand, data having no area to be stored on the optical disc (No in step 901) is stored in the information storage buffer 350 (step 903). After all the AV data transmitted from the DTV 110 is recorded or stored, the command processing means 330 transmits an AV / C command completion notification to the DTV 110 via the asynchronous processing means 320 (step 904).
[0039]
Thus, the AV data information transfer process from the DTV 110 to the optical disc recorder 120 is completed.
Next, reading of AV data information will be described.
FIG. 9 shows the data structure of an AV / C command indicating a read instruction.
In the figure, an AV / C command includes an operation code 1000 indicating instruction content (data read), auxiliary information 1010 indicating supplementary information regarding the instruction content, a transfer length 1020 indicating the size of data to be transferred, and data to be transferred. Is formed from an address 1030 indicating a position in the AV data information.
[0040]
As with this recording instruction, the AV / C command is stored in the FCP command storage area 700 of FIG. 6 and transferred from the DTV 110 to the optical disc recorder 120.
Next, how the command for reading AV data information transferred using the data structure of FIG. 9 is processed in the optical disc recorder 120 will be described.
[0041]
FIG. 10 is a flowchart showing an AV data information read instruction in the optical disc recorder 120.
The AV / C command transmitted from the DTV 110 is received through the asynchronous processing unit 320, and the command processing unit 330 analyzes the command (step 1100).
[0042]
The command processing means 330 extracts the AV / C command from the command storage area 700, interprets the operation code 1000, etc., and determines the processing content. Next, the command processing means 330 determines whether or not each of the AV data information indicated by the received AV / C command (recording date / time data 440, title data 450, content information data 460) is recorded on the optical disc ( Step 1101).
[0043]
This determination is performed as follows, for example. First, the command processing means 330 specifies what the data format of the optical disc loaded in the optical disc drive 370 is. This specification may be the same as that in step 901.
Next, the command processing unit 330 detects the data type that the data format of the mounted optical disk permits recording. This detection may be the same as that in step 901.
[0044]
Then, the command processing means determines whether the data type of the AV data information instructed to be read by the received AV / C command matches the previously detected data type, and if it matches, it is recorded on the optical disc. If it does not match, it is determined that it is not recorded on the optical disc.
If the area to be stored on the optical disk is defined (Yes in step 1101), the command processing means 330 reads from the optical disk via the optical disk drive control means 360 (step 1102).
[0045]
On the other hand, the data for which the area to be stored on the optical disc is not defined (No in step 1102), the data is acquired from the information storage buffer 350 (step 1103). After collecting the data instructed by the AV / C command in this way, the command processing unit 330 transmits the collected AV data information and the AV / C command completion notification to the DTV 110 via the asynchronous processing unit 320.
[0046]
Although the present invention has been described based on the embodiment, the present invention is not limited to the above embodiment, and may be configured as follows.
(1) If data for which an area to be stored on the optical disk is not defined is not stored in the information storage buffer 350, pseudo data may be created using related information. For example, if no title name is stored, the number of titles may be used, and the title names may be “title 1”, “title 2”, “title 3”, etc. in the order of the titles. In addition, when the content information is not stored, the content information may be created by acquiring information from the Internet or the like and extracting only necessary information. By creating data in a pseudo manner, it is possible to display data for the user and to provide convenience. In this way, the transfer processing of AV data information from the optical disc recorder 120 to the DTV 110 is completed.
[0047]
In this way, by storing data not defined for the optical disc in the information storage buffer, even if an AV / C command indicating transmission / reception of data for which an area to be recorded on the optical disc is not defined is received, the AV / C command is received. It becomes possible to finish the process without ending the C command with an error. As a result, the DTV can use the same application without being aware of the media loaded in the optical disc recorder.
(2) In the embodiment, the program content data is cited as the data for which the area to be recorded on the optical disc is not defined, but the present invention is not limited to this. For example, title data may be used.
(3) In the embodiment, the controller is a DTV, but this is not a limitation. For example, an STB (set top box) connected to a TV with an analog cable may be used.
(4) In the embodiment, the information storage buffer is a memory, but this is not restrictive. For example, an HDD (hard disk drive) or the like may be used, or a manufacturer-specific area or a user data area provided on the optical disk may be used.
(5) In the embodiment, the data not defined for the optical disc is the content information data. For example, the title data area may not be defined, or the entire data area may not be defined.
(6) The command processing means may be provided with a function that allows the same command processing to be applied instead of performing different command processing for a plurality of optical disks with different application formats to be mounted. In that case, the DTV is notified of one type, for example, “general-purpose recording / reproducing disc”, regardless of its type. On the other hand, for example, text data “DVD-RAM” is transmitted from the optical disk recorder to the DTV and displayed on the screen to allow the user to check the loaded media. As a result, it is possible to simplify the command processing without making the DTV aware of a plurality of types of discs or causing confusion to the user, and it is possible to reduce the burden on application development.
(7) In the embodiment, the DTV and the optical disc recorder are connected to the 1394 bus. For example, an HDD recorder may be connected. In this case, if the AV data information transmitted / received between the DTV and the HDD recorder is the same as the AV data transmitted / received between the DTV and the optical disk recorder, the application development of the DTV can be facilitated.
(8) In the embodiment, the data transferred by the AV / C command is AV data information, but this is not a limitation. For example, data indicating device settings may be used.
(9) In the embodiment, the recorder uses an optical disk. For example, a recorder using an HDD may be used.
(10) In the embodiment, IEEE 1394 is cited as the digital interface, but this is not a limitation. For example, USB or Ethernet (registered trademark) may be used.
(11) In the embodiment, an example is shown in which the optical disc recorder 120 performs recording and reading processing corresponding to one optical disc. However, the optical disc recorder 120 may be configured to correspond to a plurality of optical discs.
[0048]
In that case, when recording the AV data information in the information storage buffer 350, the optical disc recorder 120 acquires the disc identifier (for example, a serial number) of the mounted optical disc 372, and the disc identifier, AV data information, Are recorded in the information storage buffer 350. In this manner, when recording, AV data information can be recorded in the information storage buffer 350 by being divided into a plurality of optical disks.
[0049]
When reading AV data information, a disk identifier is acquired from the mounted optical disk 372, and the AV data information recorded in the information storage buffer 350 is associated with the disk identifiers of a plurality of optical disks by the disk identifier. The AV data information corresponding to the disc identifier of the loaded optical disc is identified and read out.
