  1 is a CPU (Central Processing Unit) for controlling the tuning operation of the tuner 2, the encoding operation of the encoder 4, the decoding operation of the decoder 7, and the operation of the write / read control unit 6. 10. Storage units 11 and 12 including RAM (Random Access Memory) and ROM (Read Only Memory) for storing various information including information (program, data, etc.) for CPU 10 to control them, external Receives an instruction / instruction by an infrared signal from a remote controller (abbreviated as a remote controller) 14 provided in the system, converts it into data, and supplies it to the CPU 10; an OSD (On Screen Display) circuit 15; 17 and an EPG (Electric Program Guide) extraction unit 18. The EPG extraction unit 18 may not be provided.

  Here, the DVD 16b may be a DVD-R, a DVD-RAM (also referred to as a DVD-RW (Digital Versatile Disc ReWritable)), or the like.

  The OSD circuit 15 creates drawing data based on the digital information given from the CPU 10 and outputs it to the analog conversion unit 8. When the analog conversion unit 8 inputs the drawing data, the analog conversion unit 8 converts only the drawing data into analog and outputs it to the output unit 9. Alternatively, the drawing data and the data read from the HD 5b or DVD 16b and given through the decoder 7 are converted to analog and output to the output unit 9. Therefore, an image based on the given data is displayed on the output unit 9.

  When the command from the remote controller 14 is not input, the input unit 13 may include various switches and buttons operated by the user for inputting commands / instructions from the outside.

  The remote controller 14 includes a dubbing key 141 for executing dubbing, an index search key 142, a cursor key 143, and a menu key 144 described later. The cursor key 143 includes a plurality of types of keys for moving a pointer such as a cursor displayed on the output unit 9 in the up, down, left, and right directions. In the present embodiment, the dubbing key 141 also has a manual title dividing function.

  The EPG extraction unit 18 extracts EPG information of program data transmitted together with a broadcast signal from digital information input via the antenna 1, the tuner 2, and the digital conversion unit 3, and gives the extracted EPG information to the CPU 10. .

  Information writing (recording) / reading (reproduction) on the HD 5b by the HDD 5a, information writing (recording) / reading (reproduction) on the DVD 16b by the DVD drive 16a, and the video tape 20b by the video tape device 20a. Information is written (recorded) / read (reproduced) through the write / read control unit 6 under the control of the CPU 10. The writing / reading control unit 6 selects which medium is to be written (recorded) / read (reproduced) and gives an operation command.

  The video tape device 20a also writes a VISS signal to be described later on the video tape 20b under the control of the write / read control unit 6.

  In the following description, it is assumed that the data to be dubbed is video data. However, the data is not limited to video data, and may be audio data or both. In the present embodiment, “dubbing” refers to transferring recorded data recorded on a certain recording medium to another recording medium for re-recording.

  Normally, when dubbing is performed between a disk medium typified by HD5b or DVD16b and a tape medium typified by video tape 20b, once dubbing is started, a series of video data, i.e., one content is recorded until dubbing is completed. As recorded.

  Here, in the case of a disc medium on which digital data is recorded, “one content” is a data group called a title or a program, and is video data managed by one management data. In the case of a tape medium on which analog data is recorded, it means video data in which VISS (VHS Index Search System) is not written in the middle except at the start of recording. This VISS is usually written at the start of recording (including dubbing) and is a signal that can identify the start of recording.

  Here, VISS will be briefly described. Normally, when recording on the video tape 20b, a pulse signal called a CTL (control track signal) signal is recorded in order to control the running of the tape during reproduction. In general, the duty of the pulse of the CTL signal is changed at the start of recording so that each content can be searched. A special duty CTL signal written so that the recording start position can be distinguished from other parts in this way is referred to as a VISS or VISS signal. In the present embodiment, the video data at the position where the VISS is written can be cued by operating the index search key 142 of the remote controller 140 during playback or when playback is stopped.

  As described above, when dubbing between a disk medium on which digital data is recorded and a tape medium on which analog data is recorded, if the content (hereinafter referred to as “title”) is to be divided at the dubbing destination, the dubbing is temporarily performed in the middle. It takes time and effort to stop and restart.

  In order to eliminate such annoyance, the composite data recording device of the disk medium and the tape medium in the embodiment of the present invention divides the title at a position desired by the user. In the following description, dubbing is performed between the HD 5b and the video tape 20b. However, it may be performed between the DVD 16b and the video tape 20b. Further, in this embodiment, dubbing is possible in both directions, but dubbing may be possible only in either one.

  In the first embodiment of the present invention, processing (dubbing processing) executed when dubbing between the HD 5b and the video tape 20b will be described with reference to the flowcharts of FIGS. Note that the processing shown in these flowcharts is realized by the CPU 10 reading and executing a program stored in advance in the storage unit 11, for example.

  Referring to FIG. 2, first, CPU 10 displays a dubbing setting screen (step S2). A display example of the dubbing setting screen is shown in FIG.

  Referring to FIG. 3, in display area 31, information to be input by the user, for example, “title division time” and “title division number” (hereinafter referred to as “ Also referred to as “Title Division Information”). The “title division time” is information representing a unit time (minute) in which title division is automatically performed, and the “title division number” is information representing the number of times title division is automatically performed.

  For example, if the title division time is 60 minutes and the number of title divisions is 3, title division is automatically performed three times every 60 minutes. When the number of title divisions is 0, automatic title division processing is not performed, and title division is performed manually by the user.

  In addition, the display area 32 displays key guidance of the remote controller 140 to be operated by the user in order to input the title division information of the display area 31. For example, it is indicated that the up / down key of the cursor key 143 of the remote controller 140 should be operated in order to select the numerical value of each title division information. Further, it is shown that the right key of the cursor key 143 should be operated in order to determine the numerical value input by operating the up and down keys. Further, it is indicated that the menu key 144 should be operated in order to end the dubbing setting.

  Referring to FIG. 2 again, CPU 10 accepts input of title division information from the user (step S4). Then, the CPU 10 determines whether an end instruction is input from the user (step S6). Until it is determined that an end instruction has been input from the user (NO in step S6), the processes in steps S2 and S4 are repeated.

  If it is determined in step S6 that an end instruction has been input from the user (YES in step S6), the process proceeds to step S8.

  In step S8, the CPU 10 determines whether or not the number of title divisions input by the user is zero. If it is determined that the number of title divisions is 0 (YES in step S8), manual division processing described later is executed (step S10). If it is determined that the number of title divisions is not zero (NO in step S8), automatic division processing described later is executed (step S12).

  As described above, in this embodiment, it is determined whether the number of title division is 0 or not, and it is determined whether automatic division or manual division is performed. For example, first, automatic division is performed. Alternatively, the user may select a menu for manual division. Then, a screen as shown in FIG. 3 may be displayed only when automatic division is selected.

  First, the manual division process in step S10 will be described with reference to the flowchart of FIG.

  First, the CPU 10 starts dubbing a title previously designated by the user (step S22). Subsequently, the CPU 10 determines whether or not the dubbing key 141 is input from the user (step S24). If it is determined that the dubbing key 141 is input from the user (YES in step S24), the process proceeds to step S26. On the other hand, if it is not determined that the dubbing key has been input (NO in step S24), the process proceeds to step S28.

  In step S26, the CPU 10 performs title division processing. For example, when dubbing from the HD 5b to the video tape 20b is being executed, the CPU 10 causes the video tape device 20a to write VISS. Further, when dubbing is being executed from the video tape 20b to, for example, the HD 5b, the CPU 10 creates another title on the HD 5b. When the process of step S26 ends, the process proceeds to step S28.

  In step S28, the CPU 10 determines whether or not the dubbing is finished. If it is not determined that dubbing has been completed (NO in step S28), the process returns to step S24. On the other hand, when it is determined that the dubbing is finished, the series of dubbing processes is finished.

  As described above, when the title dividing process is performed manually, the user can divide the title at a position where the user wants to divide without considering the time after several minutes. In addition, it is not necessary to perform the troublesome operation of temporarily stopping and restarting the dubbing operation, and the conventional labor can be reduced. This also leads to a reduction in dubbing time.

  Next, the automatic division process shown in step S12 of FIG. 2 will be described using the flowchart of FIG.

  Referring to FIG. 5, first, CPU 10 starts dubbing of a title previously designated by the user (step S32). Subsequently, the CPU 10 starts counting the title division time based on the signal from the timer 17 (step S34).

  Next, the CPU 10 determines whether there is a title division remaining number and whether the counted time has passed the title division time set by the user (step S36). The “title division remaining number” is information indicating how many times the title division process is performed. Therefore, in this embodiment, since the number of title divisions is initially 1 or more, there is always a remaining number of title divisions.

  If it is determined in step S36 that there is a remaining title division and the title division time has elapsed (YES in step S36), the process proceeds to step S38. On the other hand, if it is determined that there is no remaining title division, or that the title division time has not elapsed even though there is a remaining title division (NO in step S36), the process proceeds to step S46.

  In step S38, the CPU 10 executes title division processing. For example, when dubbing is being performed from the HD 5b to the video tape 20b, the CPU 10 causes the video tape device 20a to write VISS. When dubbing from the video tape 20b to the HD 5b has been executed, the CPU 10 creates another title on the HD 5b.

  Then, the CPU 10 subtracts “1” from the title division number (step S40). Subsequently, the CPU 10 determines whether or not the remaining number of title divisions after subtraction has become “0” (step S42). If it is determined that the remaining number of title divisions is not zero (NO in step S42), the process returns to step S36. On the other hand, if it is determined that the number of title divisions has become zero (YES in step S42), CPU 10 stops counting the title division time (step S44). When the process of step S44 ends, the process proceeds to step S46. In this way, the processes in steps S36 to S40 are repeated until the remaining number of title divisions becomes zero.

  In step S46, the CPU 10 determines whether or not the dubbing of the designated title has been completed. If it is determined that dubbing has not ended (NO in step S46), the process returns to step S36. On the other hand, when it is determined that dubbing has been completed (YES in step S46), a series of dubbing processes is terminated.

  As described above, when the title dividing process is automatically performed, the user can divide the title at a desired position without performing any operation during dubbing. Therefore, if the user only sets the dubbing, the user may be on the spot. Further, as in the case of manual operation, it is not necessary to perform a troublesome operation of temporarily stopping and restarting the dubbing operation, and the conventional labor can be reduced. This also leads to a reduction in dubbing time.

  In the present embodiment, the title division time is counted based on the signal from the timer 17, but the title division time may be measured by providing a separate counter. Further, when the process of step S40 (title division number subtraction process) is completed, the title division time count may be reset and timed.

  Here, for example, after the dubbing process has been completed when the title division is set to be performed three times every 60 minutes in the above step S4, or when the user manually operates the dubbing key 141 three times every 60 minutes. Are conceptually shown in FIG.

  FIG. 6A shows an example when dubbing is performed from the HD 5b to the video tape 20b, and FIG. 6B shows an example when dubbing is performed from the video tape 20b to the HD 5b.

  Referring to FIG. 6A, when a 240-minute title recorded on HD 5b is dubbed onto video tape 20b, VISS is written three times every 60 minutes. That is, the dubbing destination video tape 20b is divided into four titles. As a result, the user can search for the title by operating the index search key 142.

  Referring to FIG. 6B, when a 240-minute title recorded on the video tape 20b is dubbed to the HD 5b, another title is created three times every 60 minutes. That is, in the dubbing destination HD 5b, four management data are created and four titles are created. In this case, the title name of each management data may be, for example, the date and time when dubbing was executed, or may be a number such as 1, 2, 3, 4. The recording time length of each management data is 60 minutes. Thus, by creating four titles, the user can handle them as independent titles. The management data includes address information in addition to the title name and recording time length. Further, the title name may include a medium name (for example, a VCR) and a speed of the dubbing source.

  In the present embodiment, both the title division time and the number of title divisions are used as the title division information, but either one may be used. For example, in the case of only the title division time, the title division processing can be performed for each set time regardless of the number of times. Further, in the case of only the number of title divisions, it is possible to divide the titles evenly by dividing the total time of the dubbing source title by the number of title divisions.

  Further, the title division information may be set in more detail. For example, the title division time may be input every number of times, such as 30 minutes after the first time and 60 minutes after the second time.

  Instead of the DVD 16b, for example, an optical medium or the like in which a program is recorded can be read by a drive device, and the program in the storage unit 11 can be updated.

  The title dividing method performed by the composite data recording apparatus of the present invention can also be provided as a program. Such a program can be recorded on an optical medium such as a CD-ROM (Compact Disc-ROM) or a computer-readable recording medium such as a memory card and provided as a program product. A program can also be provided by downloading via a network.

  The provided program product is installed in a program storage unit such as a memory and executed. The program product includes the program itself and a recording medium on which the program is recorded.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
