The present invention relates to a data connection recording and reproducing method of a multi-recording medium. For example, in a composite video apparatus in which three or more recording devices are integrated, data recording capacity is increased while recording data on any one recording medium. The present invention relates to a data connection recording and reproducing method of a multi-recording medium for connecting and recording data to another recording medium, and connecting and reproducing the connected and recorded data normally.

FIG. 1 shows a configuration of a general composite video apparatus. For example, in a composite video apparatus in which a DVD recorder and a hard disk recorder are integrated, an optical disc 10 and an optical disc are provided. The pickup 11, the VDR (Video Disc Record) system 12, the first microcomputer 13, and the first memory 14 are included, and the hard disk 20 and the HDR (HDD Record) system 21 are included. The second microcomputer 22, the second memory 23, and an interface unit 24 for connecting to an external connection device may be included.

On the other hand, the user with the composite video device, the user wants to record the data stream, such as the data stream of the broadcast program provided through digital broadcasting, on an optical disc 10 such as a rewritable DVD (RW-RW) or Alternatively, the hard disk 20 can be recorded and stored.

For example, in the first microcomputer 13, the VDR system 12 is operated and controlled in response to a user's request, so that the data stream received through the interface unit 24 is recorded on the optical disc 10. As shown in Fig. 2, if the data recording capacity is insufficient (Data Full) while recording the data stream in the data area of the optical disc, the data recording operation is stopped (Rec_Stop). The data stream recorded up to that time is classified and managed as a new title (eg, Title # m + 1).

Further, title information (eg, Title # m + 1_Info) corresponding to the new title is generated and recorded and managed as navigation information in a lead-in area of the optical disc. For example, the title As shown in FIG. 2, the title start address (Title_SA) and the title end address (Title_EA), the title name (Title_Name), attribute information on video and audio data, and the like can be recorded. have.

On the other hand, when the user requests to write data to the hard disk, the second microcomputer 22 operates the HDR system 21 to control the data stream received through the interface unit 24. If the data recording capacity is insufficient while recording the data stream in the data area of the hard disk, for example, the data recording operation is stopped or the previously recorded data is recorded. After the deletion, a series of overwrite write operations for recording new data are performed.

When the data recording operation is stopped, the second microcomputer 22 classifies and manages the recorded data streams into new titles, generates title information corresponding to the new titles, and Recording is managed in the header area as file system information.

However, in the general composite video apparatus, as described above, when the data recording capacity becomes insufficient while recording data on the optical disc, the recording operation is automatically stopped, so that all data streams received in real time cannot be continuously recorded. The problem of becoming impossible becomes.

In addition, if the data recording capacity is insufficient while recording data on the hard disk, the recording operation is stopped or a superimposed recording operation for recording new data after deleting previously recorded data is performed. It is not possible to continuously record the data stream received or the previously recorded important data is wrongly deleted.

On the other hand, in recent years, it is expected to develop and commercialize a composite video device having three or more recording devices integrated therein. In the composite video device as described above, data is recorded while recording data on any one recording medium. When the capacity is insufficient, there is no effective solution yet to connect and record data to another recording medium and to connect and reproduce the connected and recorded data normally. Therefore, it is urgently required to prepare the solution.

Accordingly, the present invention was created in view of the above problems and circumstances, and for example, in a composite video apparatus in which three or more recording devices such as a DVD recorder, a hard disk recorder, and a memory card recorder are integrated, If the data recording capacity is insufficient while recording data on either the hard disk or the memory card, the recording medium is assigned to each recording medium according to the user selection or the size of the free recording capacity. A data connection recording and reproducing method of a multi-recording medium for connecting and recording data on a specific recording medium to which priority is given and referring to priority information, and connecting and recording the connected recorded data normally. It is to provide the purpose.

In order to achieve the above object, a data connection recording method of a multi-recording medium according to the present invention, when recording data on any one of the three or more recording media, when the recording capacity is insufficient, each recording medium Confirming priority information assigned to the first step; Selecting a specific recording medium to which the highest priority is given based on the priority information, and then connecting and recording data on the specific recording medium; And three steps of separately managing the linked recorded data into different titles, generating management information for connecting and reproducing the respective titles, and recording and managing the recorded data with each title information.

In addition, the data connection recording method of the multi-recording medium according to the present invention, before performing the data recording operation, step 1 of comparing the data capacity to be recorded and the free recording capacity of the specific recording medium; A second step of confirming priority information given to each recording medium and setting a connection recording order when a connection recording operation is required as a result of the checking; In step 3, connecting and recording data on different recording media according to the set connection recording order; and separately managing and managing the connection recorded data into different titles, and managing information for connecting and reproducing the respective titles. And four steps of generating and recording and managing each piece of title information,

In addition, the data connection recording method of the multi-recording medium according to the present invention, before performing a data recording operation, a step of comparing and confirming the sum of the data capacity to be recorded and the free recording capacity of each recording medium; As a result of the checking, when the data capacity to be recorded is larger than the sum of the free recording capacities of the respective recording media, displaying the OSD image to guide the normal recording impossible; And after displaying the OSD image, selectively performing a data recording operation according to a user's selection.

In addition, according to the present invention, the method for data connection reproduction of a multi-recording medium includes retrieving title information corresponding to any one title requested to be reproduced from each of the titles connected to and recorded on three or more recording mediums, and selecting the title. Selective regeneration; If the title is to be reproduced, step 2 of selecting and reproducing, on another recording medium, the titles recorded in the highest priority by referring to the management information recorded in the title information; And if the title is to be reproduced, three steps of selecting and reproducing the titles linked in the next order on another recording medium with reference to management information recorded in the title information.

Hereinafter, exemplary embodiments of a data connection recording and reproducing method of a multi-recording medium according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 3 shows a configuration of a composite video apparatus to which the present invention is applied. For example, a composite video apparatus in which a hard disk recorder, a DVD recorder, and a memory card recorder are integrated may include a hard disk 50 and HDR. System 51, optical disk 52, optical pickup 53, VDR system 54, memory card 55, MCR (Memory Card Record) system 56, microcomputer 57, memory 58, and The OS D generation unit 59 and the input / output unit 60 may be configured to be included.

On the other hand, in the hard disk 50, the memory card 55, and the optical disk 52, for example, a rewritable DVD (RW-RW), as shown in FIG. 4, priority information (Priority_Info. The priority information is connected to enable recording of data by selecting another recording medium when data recording capacity is insufficient while recording data on any one recording medium. As the recording priority information, it can be arbitrarily selected and designated by the user, or the spare recording capacity (Remain) of each recording medium can be automatically designated in ascending order.

For example, as shown in Fig. 4, when the priority information given to the hard disk HDD is '01', it corresponds to the first (1st) connection recording rank and is rewritable DVD (DVD-). If the priority information assigned to RW is '10', it corresponds to the second (2nd) connection record rank, and if the priority information given to the memory card is '11', the third (3th) It corresponds to the concatenated recording rank of, and the remaining priority information '00' may be allocated as a reserved value.

In addition, the microcomputer 57 performs a data connection recording operation by searching and searching the priority information. For example, the microcomputer 57 may record data received from the outside in response to a user's request. -RW), when the data recording capacity is insufficient, the priority information given to the hard disk 50 (eg '01') and the priority information given to the memory card 55 (eg '11') is compared and data is connected and recorded to the hard disk 50 having the highest priority among them.

In addition, if data recording capacity is insufficient while recording data on the hard disk 50, data is concatenated and recorded on the memory card 55, which is the remaining recording medium. ) And record the data recorded in the hard disk 50 and the memory card 55 into different titles (eg, Title # m + 1, Title # n + 1, Title # k + 1). Then, the link record information is recorded in the title information corresponding thereto.

For example, in the case of a recordable DVD (eg, DVD-R / RW), as shown in FIG. 4, a reserved area included in the video manager information management table (VMGI_MAT) defined in the DVD standard, For example, in the last free space (e.g., RBP 360 t0 511), the link recording status (Link_Rec_Flag), the link recording order (Link_Rec_Order), the link recording medium (Link_Rec_Media), and the title number (or address) recorded in the link ( Link record information for identifying a Link_Rec_Title Number (or Address) may be included and recorded.

On the other hand, the information indicating whether or not the link recording and the link recording order can be recorded and managed by the 2-bit flag 'Link_Flag', for example, if 'Link_Flag = 01', the link recording operation is first performed on the optical disk. In the case of 'Link_Flag = 10', the second, and 'Link_Flag = 11', the third time, and 'Link_Flag = 11' may be allocated as a reserved value.

Information indicating the title number recorded in connection with the connection recording medium may be recorded and managed by 'HDD_Title # n + 1', wherein 'HDD' indicates that the connection recording medium is a hard disk, and the 'Title # n + 1 'represents the title number recorded on the hard disk.

6 is a flowchart illustrating an operation of a data connection recording method of a multi-recording medium according to the present invention. For example, the microcomputer 57 operates the VDR system 54 at the request of a user. When the data received from the outside is recorded on the rewritable DVD 52 (S10), when the recording capacity of the rewritable DVD becomes insufficient (S11), it is given to the hard disk as shown in FIG. The priority information (eg, '01') and the priority information (eg, '11') given to the memory card are checked (S12).

For example, the priority information may be retrieved at a time when it is determined that the data recording capacity is insufficient or may be searched and stored in advance before performing a data recording operation. In the case where it is determined through the information checking process that the recording medium having the highest priority is the hard disk (S13), the HDR system 51 is operated to control the data connection to the hard disk as shown in FIG. (Link Record) (S14).

When the data recording capacity is insufficient while recording data on the hard disk (S15), the microcomputer 57 operates the MCR system 56 to control the memory card 55, which is the remaining recording medium. The data is connected and recorded (S16).

On the other hand, after the series of data connection recording operations as described above are finished (S17), the microcomputer 57 stores the data recorded on the rewritable DVD as shown in FIG. Title # m + 1), the data recorded on the hard disk is classified and recorded by the n + 1 th title (Title # n + 1), and the data recorded on the memory card is k + 1th It is recorded separately by title (Title # k + 1).

In addition, in the microcomputer 57, Link_Flag = '01' is recorded in the title information (Title_Info # m + 1) corresponding to the m + 1th title recorded separately on the rewritable DVD, and the first on the rewritable DVD. In addition to indicating that the first connection recording operation has been performed, HDD_Title # n + 1 is recorded to indicate that the next connection-recorded data is recorded on the hard disk as the n + 1th title (Title # n + 1).

In addition, Link_Flag = '10 'is recorded in the title information (Title_Info # n + 1) corresponding to the n + 1th title recorded separately on the hard disk, indicating that the second connection recording operation is performed. MC_Title # n + 1 is recorded to indicate that the next connected recorded data is recorded in the memory card as the k + 1th title (Title # k + 1).

Meanwhile, Link_Flag = '11 'is recorded in the title information (Title_Info # k + 1) corresponding to the k + 1th titles recorded on the memory card, indicating that the third link recording operation has been performed and the DVD_Title By recording # m + 1, a series of title information recording management operations for performing association with the n + 1th title (Title # n + 1) of the first connected recordable rewritable DVD is performed (S18).

As a result, when the microcomputer 57 reads and reproduces data recorded in different titles on the rewritable DVD, the hard disk, and the memory card, respectively, as shown in FIG. Read and reproduce the m + 1th title (Title # m + 1) recorded on the rewritable DVD 52 by referring to the connection recording information recorded in the recording medium, and then recorded on the hard disk 50. The n + 1th title (Title # n + 1) is read and reproduced.

The k + 1th title (Title # k + 1) recorded on the memory card 55 is read out and reproduced. In the microcomputer 57, the k + 1th title (Title # k + 1) is read. After the playback is completed, it is determined that the title (e.g. DVD_Title # m + 1) associated with it is the m + 1th title (Title # m + 1) of the rewritable DVD 52 previously played back, The data reproducing operation is stopped.

9 is a flowchart illustrating an operation of a data connection recording method of a multi-recording medium according to another embodiment of the present invention. For example, in the microcomputer 57, a broadcast received from the outside in response to a user's request. When the data recording mode for recording the program data on the rewritable DVD 52 is set (S30), the data capacity of the broadcast program to be recorded is detected. In the microcomputer 57, the digital broadcasting is performed. After searching the EPG (Electronic Program Guide) provided through the electronic program guide, the broadcasting time of the broadcasting program is checked, and the broadcasting time and the data transmission rate are calculated to detect and confirm the data capacity of the broadcasting program to be recorded. (S31).

On the other hand, the microcomputer 57 compares the data capacity of the broadcast program detected as described above with the spare recording capacity (Remain) of the rewritable DVD (S32). If it is smaller than the recording capacity (S33), the normal recording operation of recording the broadcast program data on the rewritable DVD is performed (S34).

On the other hand, if the data capacity is larger than the free recording capacity, as described above, priority information (eg, '01') given to the hard disk and priority information (eg, '11') given to the memory card, as described above. (S35), the connection recording order is determined, and the microcomputer 57 designates the rewritable DVD 52 designated by the user as the recording medium for recording the broadcast program as the first recording medium. The priority information sets the connection recording order using the hard disk as the second recording medium and the memory card as the third recording medium (S36).

Subsequently, when the microcomputer 57 starts a data recording operation (S37), the microcomputer 57 sequentially controls the VDR system 54, the HDR system 51, and the MCR system 56 to record the connection. The data connection recording operation is performed in the order (S38), and when the data recording operation is terminated (S39), as described above with reference to FIG. 7, the data recorded in each recording medium is recorded separately in different titles. In addition, title information for connecting and reproducing each title is recorded and managed (S40).

FIG. 10 is a flowchart illustrating an operation of a data connection recording method of a multi-recording medium according to another embodiment of the present invention. For example, in the microcomputer 57, received from the outside in response to a user's request. When setting a data recording mode for recording broadcast program data on an arbitrary recording medium (S50), the data capacity of the broadcast program to be recorded is searched and referred to as EPG information or the like as described above. Detection is confirmed (S51).

Then, the microcomputer 57 detects the free recording capacity (Remain) of the hard disk 50, the rewritable DVD 52, and the memory card 55 included in the device, respectively, and then records each recording medium. The sum of the capacities is calculated and compared with the data capacities of the broadcast program to be recorded (S52). For example, when the data capacities are larger than the sum of the spare recording capacities (S53), the OSD generator ( 59), the OSD image of the error message indicating that all of the broadcast program data cannot be recorded normally is outputted and displayed (S54).

On the other hand, in the OS video, for example, as shown in FIG. 11, the data capacity of a broadcast program (e.g., 1.2 GBytes) and the total free recording capacity (e.g., 1.1 GBytes) of each recording medium are errors. Message), and a menu item (eg, Rec_Start) may be displayed for performing a data recording operation despite the normal recording being impossible. In this case (S55), the microcomputer 57 searches for and confirms priority information given to each recording medium (S56).

Then, based on the priority information, the connection recording order of the hard disk 50, the rewritable DVD 52, and the memory card 55 is set, and then broadcast program data is output in accordance with the connection recording order. After the data recording operation is terminated, as described above with reference to FIG. 7, data recorded on each recording medium is recorded separately in different titles, and each title is connected. The title information for reproduction is recorded and managed (S58).

Meanwhile, navigation information for a predetermined data format such as MP3-Audio is recorded in a specific area of the memory card 55, for example, in the header area, so that the memory card is stored in the device. When 55 is inserted and inserted, the microcomputer 57 checks the data format information recorded in the header area of the memory card, and changes the data format accordingly.

For example, when the data format is MP3-Audio, the microcomputer 57 operates the VDR system 54 and the MCR system 56 to control an optical disk (for example, DVD). The audio data recorded on the back and the like is converted into an MP3 audio format on the memory card 55 to perform a series of audio data recording operations.

The information about the data format is not necessarily navigation information. For example, the format of the files recorded in the memory card is read so that the format of the file is an audio format such as MP3 or WMA. In this case, any one of them may be selected to convert the audio data of the optical disc into the selected format.

Also, since a memory card can generally be used in connection with a playback device of a specific data format such as MP3-Player, the memory card receives format information required to be stored in the memory from the playback device and automatically performs file format conversion based on the playback information. It is also possible.

For reference, the present invention may be applied to a Blu-ray Disc, a Memory Stick, or other various recording media, and the information for indicating the connection record may be provided for each recording medium. Records may be managed in a manner consistent with the unique methods defined in the standard.

As described above, preferred embodiments of the present invention are disclosed for purposes of illustration, and those of ordinary skill in the art can further various other embodiments within the spirit and technical scope of the present invention disclosed in the appended claims. Improvements, changes, substitutions or additions will be possible.

The data connection recording and reproducing method of the multi-recording medium according to the present invention constituted and constructed as described above is, for example, in a composite video device in which three or more recording devices such as a DVD recorder, a hard disk recorder, and a memory card recorder are integrated. Priority is given to each recording medium according to the user's selection or the size of the remaining recording capacity when the data recording capacity is insufficient while recording data on any one recording medium. By searching and referring to the information, the data is concatenated and recorded from a specific recording medium to which the highest priority is given, so that the data can be concatenated and recorded according to a desired order or the size of the free recording capacity. When the title is played back, the management information recorded in the title information is referred to. By connecting and reproducing the different recorded titles normally, the recording operation can be effectively prevented due to lack of data recording capacity, and the data can be connected more efficiently to three or more recording media. It is a very useful invention that can be recorded.
