In addition, storage units 11 and 12 including a RAM (Random Access Memory) and a ROM (Read Only Memory) for storing various types of information including information (programs, data, etc.) for the CPU 10 to control them, and externally An input unit 13, an OSD (On Screen Display) circuit 15, and a detachable recording medium that receives an instruction / instruction by an infrared signal from a provided remote controller (abbreviation of remote controller) 14, converts the command / instruction to data, and supplies the data to the CPU 10. The DVD 16, the timer 17 that performs timekeeping, and an EPG (Electric Program Guide) extraction unit 18 are provided. The EPG extraction unit 18 may not be provided.

  Here, the DVD 16 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 drawing data is input, the analog conversion unit 8 converts only the drawing data into analog, or converts the drawing data and data read from the HDD 5 or DVD 16 and applied through the decoder 7 into an analog output unit. 9, an image based on the given data is displayed on the output unit 9.

  In the present embodiment, it is assumed that the storage unit 11 includes a memory, such as a flash memory, that can hold the recorded contents even when the power supply is cut off.

  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 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. .

  Note that writing (recording) / reading (reproduction) of information on the HD by the HDD 5 and writing (recording) / reading (reproduction) of information on the DVD 16 are performed under the control of the CPU 10. 6 is performed. Here, the read / write control unit 6 is provided in common for the HDD 5 and the DVD 16, but the write / read control unit 6 may be provided individually.

  In the following description, it is assumed that data to be recorded or dubbed is video data. However, the data is not limited to video data, and may be audio data or both. In the present embodiment, “recording” refers to writing video data based on a broadcast signal received via the antenna 1 on a recording medium. “Dubbing” refers to transferring recorded data recorded on one recording medium (HDD 5) to another recording medium (DVD 16) for re-recording.

  The video data is stored in the DVD 16 and the HD (not shown). In the following description, the video data is described as being stored in the DVD 16 and the HDD 5.

  FIG. 2 is a diagram illustrating a configuration example of the remote controller 14. Referring to FIG. 2, remote controller 14 is instructed to operate power key 21 for changing the power-on state of data recording / reproducing apparatus 100, DVD key 22 for instructing an operation on DVD 16, and an operation on HDD 5. HDD key 23 for recording, number key 24 for inputting numbers “1” to “0” and “+10”, and recording (recording) video data received via antenna 1 on DVD 16 or HDD 5 A recording key 25, a reproduction key 26 for giving an instruction to reproduce video data recorded on the DVD 16 or the HDD 5, a fast-forward key 28 for fast-forwarding the reproduction, a rewind key 29 for rewinding the reproduction, Stop key 27 for stopping recording, menu key 41 for displaying various menus, enter button 42, cursor key 43 to 46 are included. The cursor keys 43 to 46 are 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.

  Hereinafter, the case where the DVD key 22 is operated is referred to as “DVD mode”, and the case where the HDD key 23 is operated is referred to as “HDD mode”. For example, when the recording key 25 is operated during the DVD mode, video data is written on the DVD 16 based on the broadcast signal received via the antenna 1. As described above, in the embodiment of the present invention, the user can select the recording medium of the video data based on the broadcast signal from either the DVD 16 or the HDD 5.

  The remote controller 14 may not be configured as shown in FIG. 2. For example, the remote controller 14 may have a configuration in which a recording key dedicated for DVD and a recording key dedicated for HDD are provided separately.

  For example, it is assumed that the menu displayed by operating the menu key 41 includes at least a menu for dubbing from the HDD 5 to the DVD 16. As a result, the user can store video data in the large-capacity HDD 5 and dubb it to the DVD 16 as necessary.

  FIG. 3 is a flowchart showing the flow of the recording medium switching process in the first embodiment of the present invention. This processing is, for example, processing that is started by the CPU 10 when the user operates the power key 21 to turn on the power.

  Referring to FIG. 3, first, CPU 10 determines whether or not there is a key input (step S2). Wait until there is a key input (NO in step S2).

  When CPU 10 detects that a key has been input (YES in step S2), CPU 10 then detects the type of input key (step S4). If it is detected that the key type is a DVD recording key, the process proceeds to step S8. On the other hand, when determining that the type of the key is not the DVD recording key, the CPU 10 performs a process corresponding to the input key (step S6).

  Here, the determination of whether or not it is a DVD recording key is made depending on whether or not the recording key 25 is operated during the DVD mode.

  In step S8, the CPU 10 determines whether or not recording on the DVD 16 is possible. This determination is made based on, for example, whether the DVD 16 is mounted, whether the mounted DVD 16 has free space, or whether the mounted DVD 16 is not write-protected.

  If the CPU 10 determines that recording on the DVD 16 is possible (YES in step S8), recording on the mounted DVD 16 is started (step S9). Subsequently, the CPU 10 detects the presence / absence of a stop instruction (step S10). The stop instruction is detected when the user operates the stop key 27, for example. Alternatively, when the recording stop time is set in advance, it may be determined whether or not the time obtained from the timer 17 is the recording stop time, and it is determined that the stop instruction has been issued when the recording stop time is reached. If a stop instruction is detected (YES in step S10), CPU 10 ends the recording (step S11) and returns the process to step S2.

  On the other hand, when determining that recording on the DVD 16 is impossible (NO in step S8), the CPU 10 determines whether recording on the HDD 5 is possible (step S12). This determination is made based on, for example, whether the HDD 5 has free space. Since the normal HDD 5 has a large capacity, there is usually a free capacity.

  If it is determined in step S12 that recording to the HDD 5 is possible (YES in step S12), recording to the HDD 5 is executed (step S13). Subsequently, the CPU 10 detects the presence / absence of a stop instruction (step S14). The stop instruction is detected when the user operates the stop key 27, for example. Alternatively, when the recording stop time is set in advance, it may be determined whether or not the time obtained from the timer 17 is the recording stop time, and it is determined that the stop instruction has been issued when the recording stop time is reached. If a stop instruction is detected (YES in step S14), CPU 10 ends the recording (step S15) and returns the process to step S2.

  On the other hand, if it is determined in step S12 that recording to the HDD 5 is impossible (NO in step S12), the operation of the recording key 25 is invalidated (step S16). In this case, an image for informing the user that the recording has been invalidated is generated and output in the OSD circuit 15. Then, when the process of step S16 ends, the process returns to step S2.

  Thus, in this embodiment, the recording key can be validated even when recording on the DVD 16 is impossible. Then, by switching the recording destination from the DVD 16 to the HDD 5, it is possible to eliminate the inconvenience that it is necessary to install the recordable DVD 16 or that recording cannot be performed during that time.

  In addition, since the data recording / reproducing apparatus 100 according to the present embodiment can perform dubbing from the HDD 5 to the DVD 16, it can be recorded on the DVD 16 later with ease and is user-friendly.

  Such a recording medium switching process can be applied not only when the recording key 25 is operated, but also when recording to the DVD 16 is reserved. In this case, the CPU 10 compares the time obtained from the timer 17 with the recording reservation time, and makes a determination in step S8 when the recording reservation time comes (or several minutes to several seconds before). In this way, even when the DVD 16 is reserved for recording, the recording process can be surely performed.

(Modification 1)
Next, a first modification of the first embodiment of the present invention will be described. In the first modification of the first embodiment, when the recording medium switching process is executed and recorded on the HDD 5, it is managed separately from the normal recording. That is, when the recording medium switching process is executed and recorded on the HDD 5, additional information is stored in the management information of the content. Since the configuration of the data recording / reproducing apparatus in the first modification of the first embodiment is the same as that of the first embodiment, the reference numerals of the data recording / reproducing apparatus 100 shown in FIG. 1 are used, and the description here is repeated. Absent.

  FIG. 4 is a diagram showing a structure example of a title management table of the HDD 5 in the first modification of the first embodiment of the present invention. The title management table is stored, for example, in the system management area of the HDD 5 in order to manage the content (title) recorded in the data area of the HDD 5.

  Referring to FIG. 4, the title management table has title management data Bj (j = 1, 2, 3,..., M) for each title. The title management data Bj includes a title name D1, a start address D2, an end address D3, a recording time length D4, a recording date D5, a channel D6, and temporary information D7. In the temporary information D7, information indicating whether or not it is temporary is stored. Here, “temporary” indicates that the video data is recorded by performing the recording medium switching process. In the temporary information D7, for example, “OFF” is normally stored, and “ON” is stored as additional information in the case of temporary. Information (D1 to D6) other than the temporary information D7 is general essential information.

  FIG. 5 is a flowchart showing the flow of the recording medium switching process in the first modification of the first embodiment of the present invention. The same steps as those in the flowchart shown in FIG. 3 are denoted by the same step numbers, and description thereof will not be repeated here.

  CPU10 performs the process of step S2-S8 similarly to Embodiment 1. FIG.

  If it is determined in step S8 that recording on the DVD 16 is possible (YES in step S8), the temporary information D7 of the title management data Bj is set to “OFF” (step S20). Thereafter, the CPU 10 performs the processes of steps S9 to S11. In addition, it is good also as performing the process of step S20 after the process of step S9.

  If it is determined in step S8 that recording on the DVD 16 is impossible (NO in step S8), the process proceeds to step S12 and the above determination is made.

  If it is determined in step S12 that recording to the HDD 5 is possible (YES in step S12), the CPU 10 sets the temporary information D7 of the title management data Bj to “ON” (step S22). Then, when the process of step S22 ends, the processes of steps S13 to S15 are executed. In addition, it is good also as performing the process of step S22 after the process of step S13.

  FIG. 6 is a diagram showing a display example of the title list of the HDD 5 in the first modification of the first embodiment of the present invention. For example, when the user operates the menu key 41 to select a list of titles (contents) recorded in the HDD 5, a screen as shown in FIG. 6 is displayed.

  Referring to FIG. 6, for example, information of title name D1, recording date D5, channel D6, and temporary information D7 is displayed on the screen. As shown in FIG. 6, in the present embodiment, when the temporary information D7 is OFF, no special information is displayed, and when the temporary information D7 is ON, for example, “(Temporary)” is displayed. The In addition, it is not restricted to such a character, A specific mark may be displayed and you may distinguish by changing display forms, such as displaying the title name D1 by blinking.

  As described above, in the first modification of the first embodiment, the content temporarily recorded in the HDD 5 can be easily found, which is convenient when searching for the content to be dubbed later.

  The temporary information only needs to be associated with the content on which the recording medium switching process has been performed, and may be managed in a storage area other than the title management table.

(Modification 2)
Next, a second modification of the first embodiment of the present invention will be described. In the second modification of the first embodiment, the user can select whether to execute the above-described recording medium switching process. Since the configuration of the data recording / reproducing apparatus in the second modification of the first embodiment is the same as that of the first embodiment, the description of the data recording / reproducing apparatus 100 shown in FIG. Absent.

  FIG. 7 is a flowchart showing the flow of the recording medium switching process in the second modification of the first embodiment of the present invention. The same steps as those in the flowchart shown in FIG. 3 are denoted by the same step numbers, and description thereof will not be repeated here.

  CPU10 performs the process of step S2-S8 similarly to Embodiment 1. FIG.

  If it is determined in step S8 that recording on the DVD 16 is possible (YES in step S8), recording on the DVD 16 is started as in the first embodiment (step S9). Then, the processes of steps S10 and S11 are performed.

  On the other hand, when it is determined in step S8 that recording on the DVD 16 is impossible (NO in step S8), the CPU 10 displays a notification screen (step S32). For example, a message “Are you sure you want to switch to HDD recording?” Is displayed as the notification screen. An OK button and a NO button are displayed together with this message.

  Then, the CPU 10 determines whether there is a recording instruction from the user to the HDD 5 (step S34). If there is a recording instruction to HDD 5 (YES in step S34), that is, if the OK button is selected by the user, the process proceeds to step S12 and the above-described processing is performed.

  On the other hand, if there is no recording instruction to HDD 5 (NO in step S34), that is, if the user selects the NO button, the process proceeds to step S16 and the above-described processing is performed.

  As described above, in the second modification of the first embodiment of the present invention, the user can select whether to switch the recording medium as the recording destination. Therefore, for example, if there is a writable DVD 16 at hand, it can be recorded on the DVD 16 as desired by mounting it. Thereby, the trouble of dubbing video data (content) once recorded in the HDD 5 can be saved.

  In the second modification of the first embodiment, the temporary information may be stored in the management data as in the first modification.

  As described above, the first embodiment of the present invention and the first and second modifications thereof have been described using the data recording / reproducing apparatus 100 in which the HDD 5 is incorporated and the DVD 16 is detachable. However, the present invention is not limited to such a configuration. For example, instead of the DVD 16, another optical medium may be detachable, or a tape medium such as a magnetic tape may be detachable. As the tape medium, analog data may be recorded, or digital data may be recorded. Further, the HDD 5 may be built in and a plurality of removable recording media may be provided.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
