JP 11-260043 A

  Since the amount of video data is very large, when digitally recording a television broadcast, the number of programs that can be recorded on one disk recording medium is limited. Therefore, when recording reservations are set on a disk recording medium and a recorded program is managed for each disk recording medium, in a conventional apparatus, the user has ensured that the disk recording medium has enough free space for the next reserved recording. If there is not enough free space, it has been necessary to secure the free space, for example, by searching for the broadcast times that have been viewed and deleting the data.

  Such a process is very complicated, and it is considered that the precious function of managing a recorded program for each disk recording medium is not effectively utilized.

  An object of the present invention is to provide a function for assisting in solving a shortage of free space in a disk recording medium in a disk recording apparatus capable of recording a recording reservation setting on a disk recording medium and managing a recorded program for each disk recording medium. Is to provide a disk recording apparatus capable of managing a recorded program for each disk recording medium without a complicated process such as checking a free space.

  In order to achieve the above object, the present invention provides a disk recording apparatus for recording broadcast content data on a disk recording medium that can be rewritten and inserted into and removed from the apparatus. Reservation recording means for automatically recording broadcast content data, reservation erasure means for automatically deleting content data recorded on the disk recording medium at a predetermined timing according to the set conditions, and recording on the disk recording medium The reservation recording means and the reservation erasure means are read, and the reservation recording means and the reservation control means for operating the reservation erasure means based on the contents are read.

  According to such a means, by writing the reservation erasure operation setting on the disk recording medium, the previously recorded content data is automatically erased according to the setting condition. It is possible to manage recorded programs for each disk recording medium without doing so.

  Desirably, the operation input means capable of inputting the operation setting contents of the reservation recording means and the reservation erasure means from the outside, and the reservation for writing the contents of the operation settings of the reservation recording means and the reservation erasure means to the disk recording medium And setting means.

  Thereby, it is possible to set reservation recording or reservation erasure in the disk recording apparatus.

  Preferably, the reservation erasure unit may be configured to erase the content data at a timing immediately before the reservation recording is started by the reservation recording unit when there is content data to be deleted.

  With this configuration, the user does not have to think about the date and time when content data is erased, and content data is erased immediately before free space is required, reducing the troublesomeness of setting reservation erasure. The Even if you want to stop erasing content data unexpectedly, the next content data will not be erased until immediately before the scheduled recording operation. good.

  Specifically, as the setting condition of the reservation erasure means, when the remaining capacity of the disc recording medium is insufficient, when there is reproduced content data, every week, every day, Monday to Friday, Monday to Saturday, etc. It is preferable that the setting condition can be selected.

  With such a configuration, it is possible to perform reserved deletion of content data in accordance with user-desired conditions.

  As described above, according to the present invention, it is possible to perform scheduled recording and reservation erasure of a program for each disk recording medium, so that the user views a recorded program and inserts / removes a disk after setting once. For example, a series of broadcast programs such as a series drama can be reserved and recorded on a single disc for viewing. At this time, the user only needs to watch the recorded program before the reserved program is erased, and there is no need to worry that there is not enough free disk space at the time of scheduled recording.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing the overall configuration of a disk recording apparatus according to an embodiment of the present invention.

  The disk recording apparatus 1 of this embodiment is a video recorder that receives a television broadcast and records on an optical disk (for example, DVD ± RW) that can be rewritten and inserted into and removed from the apparatus. The disc recording apparatus 1 includes a TV tuner 11 that selectively receives a television broadcast signal, and a recording processing unit 12 that digitally compresses video signals and audio signals input from the TV tuner 11 and converts them into recordable digital data. An optical pickup 13 that records or reproduces data by irradiating the recording surface of the optical disc with laser light, a recording / reproducing unit 14 that transfers recording data or reproduced data in conjunction with the operation of the optical pickup 13, and digital compression The stream processing unit 15 decompresses the stream data, converts it into video data and audio data and outputs it, the disk loading unit 16 for loading / unloading the disk recording medium, and the light receiving unit that receives signals from a plurality of operation keys and the remote controller 20. An operation input unit 17 having a unit 17a for inputting an operation command from the user, and controlling the entire system Such stem controller 18 is provided.

  The system control unit 18 includes a nonvolatile memory storing a control program, a CPU (Central Processing Unit) that executes the nonvolatile memory, a RAM (Random Access Memory) that provides a work space for the CPU, and a timer such as a real-time clock that counts time 18d, a reservation storage unit 18e composed of a non-volatile memory for work that stores reservation information and does not erase data even when the power is turned off is provided.

  The disk recording apparatus 1 of this embodiment can write recording reservation information (reservation information) on a disk recording medium based on a control program stored in the nonvolatile memory of the system control unit 18. Further, when reservation information is written on a disk recording medium inserted in the apparatus, a recording reservation operation is performed based on the reservation information.

  FIG. 2 shows an image diagram of a setting menu displayed on the display at the time of setting of scheduled recording and scheduled erasure.

  When writing reservation information to a disk recording medium, with the disk recording medium inserted in the apparatus, an operation input is performed from the operation input unit 17 and an item “Set Disk Recording” is selected from the system menu. Then, a reservation recording setting screen as shown in FIG. 2 is displayed. By setting each setting item using a cursor key or the like, reservation setting is performed, and the reservation information is stored in the disc recording medium. To be written. The system controller 18 that performs the reservation setting process and its control program constitute reservation setting means.

  As shown in FIG. 2, the reserved disk recording setting items include the recording reservation day of the week, the recording reservation disclosure time and end time, the recording reservation channel, the image quality setting (“XP (high resolution)”, “normal”, “Low (low resolution)” includes automatic erasing on / off and erasing timing.

  The setting items for the day of the week for recording are “Monday” to “Sunday”, “Monday-Friday” that represents every day from Monday to Friday, “Month-Saturday” that represents every day from Monday to Saturday, and “Everyday” , And can be selected.

  In the automatic erasure ON / OFF setting, it is possible to select “ON” for automatic erasure and “OFF” for no automatic erasure.

  The setting items for the erasure timing specify the conditions for scheduled erasure. The setting items include "Every week", "Monday-Friday" for every day from Monday to Friday, and "Month" for every day from Monday to Saturday. It is possible to select “Sat”, “Everyday”, “DISC full” indicating that there is no free space for the next recording reservation, and “Played” indicating that there is content data that has been played back.

  Of these, the four selections of “Weekly”, “Monday-Friday”, “Monday-Saturday”, and “Everyday” can be selected or cannot be selected according to the setting of the day of the week for recording reservation. To do. In other words, if any of “Month” to “Day” is selected as the recording reservation day, only “Weekly” can be selected. If the recording reservation day is “Monday-Friday”, “Month” Only “Fri” can be selected, “Monday-Saturday” can be selected when the recording reservation day is “Monday-Saturday”, and “Everyday” is only when the recording reservation day is “Daily” Is made selectable.

  The contents of “Every Week”, “Monday-Friday”, “Monday-Saturday”, “Everyday”, “DISC Full”, and “Reproduced” that can be set in these items of erasure timing are as follows.

  That is, the setting contents of “Weekly”, “Monday-Friday”, “Monday-Saturday”, and “Daily” are set so that the oldest content data is deleted immediately before the next scheduled recording starts. To do. “DISC full” is such that if there is no free space for the next scheduled recording immediately before the next reserved recording is started, the content data for the reserved free space is deleted from the oldest content data. Is set to “Reproduced” is set so that if there is reproduced content data immediately before the next reserved recording is started, the content data is deleted.

  Hereinafter, with reference to the flowcharts of FIG. 3 and FIG. 4, the reservation information set as described above is set in the disk recording apparatus 1 from the disk recording medium, and the reservation processing for performing reservation recording and reservation deletion is referred to. While explaining.

  FIG. 3 is a flowchart showing the procedure of the disc insertion process executed by the system control unit 18 when the disc recording medium is inserted into the apparatus 1.

  This disk insertion process is started when a signal notifying insertion of a disk recording medium is input from the disk loading unit 16 to the system control unit 18 by opening / closing operation of the loading mechanism.

  When the disk insertion process is started, first, in step S1, a predetermined sector of the disk recording medium is accessed to check whether reservation information is written on the disk recording medium. The reservation information is read and the content is checked.

  As a result, if the reservation information is written and there is a reservation setting in the reservation information, the process proceeds to step S2, and at this step, the reservation information is stored in the reservation storage unit 18e of the system control unit 18. Reservation recording and reservation erasing operations are executed based on reservation information stored in the reservation storage unit 18e.

  After the reservation information is stored, the process proceeds to step S3, and the process proceeds to a DISC reproduction process that is generally performed when a disc recording medium is inserted. That is, in step S3, a DISC menu display for displaying a list of content data stored on the disk recording medium is performed. Then, in a subsequent step, an instruction operation from the user is awaited and a control process according to the instruction operation is performed. Since the process after step S3 can apply the process similar to the past, description is abbreviate | omitted.

  On the other hand, as a result of the reservation information check in step S1, if the reservation information is not written or if the reservation information is written but the reservation setting is not performed, the process jumps from step S1 to step S3 and continues as it is. Shift to DISC playback processing.

  FIG. 4 shows a flowchart of the reservation process executed by the system control unit.

  This reservation processing is started based on the date and time specified by the information on the day of the reservation recording and the start time stored in the reservation storage unit 18e. Specifically, a date and time that is a predetermined time (for example, 3 minutes) earlier than the designated date and time is set in the timer 18d, and when the date and time is reached, an interrupt signal is output from the timer 18d to the CPU.

  When this reservation process is started, first, the reservation information stored in the reservation storage unit 18e is read in step S11. Next, in step S12, the reservation information erasure timing is checked. If the erasure timing is "weekly", "Monday-Friday", "Monday-Saturday", or "Everyday", the process proceeds to Step S13. Transition.

  If the erase timing is “DISC full” in step S12, the free capacity of the disk recording medium and the capacity required for the reserved recording at this time are calculated. If the free capacity is smaller, the process proceeds to step S13. However, if the free space is larger, the process jumps to step S15.

  If the erase timing is “reproduced” in step S12, the management data of the content data written on the disc recording medium is read to check the presence or absence of the reproduced content data, and the reproduced content. If there is data, the process proceeds to step S13. If there is no reproduced content data, the process jumps to step S15.

  Next, in step S13, the management data of the content data is checked to determine whether there is content data to be erased in accordance with the erase timing setting. If there is content data to be erased, the process proceeds to step S14. Jump to S15.

  Specifically, in step S13, if the erasing timing is “every week”, “Monday-Friday”, “Monday-Saturday”, or “Everyday”, the start and end times on the day of the week included in these set days of the week. And the content data whose channel is the same as the reservation information setting, that is, the content data recorded previously by this reservation information is searched, and if there is the content data, the oldest content data is deleted next Specified as content data.

  Further, when the erase timing is “DISC full”, the content data for which the free space necessary for the current scheduled recording is secured is specified as the content data to be erased next in the order of the recording date and time.

  If the erase timing is “reproduced”, the reproduced content data is searched, and if there is, all of them are specified as content data to be erased next.

  If there is content data to be erased as a result of step S13 and the process proceeds to step S14, the content data is erased in step S14.

  Subsequent step S15 is processing for performing scheduled recording. That is, first, the broadcast channel set in the reservation information is switched (step S15), the recording start timing is waited (step S16), and the recording process is started (step S17).

  Next, the recording end timing is waited (step S18), the recording is ended (step S19), and a transition is made to the standby mode (step S20).

  By the control program including the processing flow of FIG. 3 and FIG. 4 described above, and the CPU of the system control unit 18 that executes them, the timer 18d and the reservation storage unit 18e, reservation recording means, reservation erasure means, and reservation control means are provided. It is configured.

  As described above, according to the disk recording apparatus 1 of this embodiment, the recording reservation setting data is written in the disk recording medium, and the recording reservation program management can be performed for each disk recording medium. Is obtained. Furthermore, by writing the reservation erasure setting on the disk recording medium, the previously recorded content data is automatically erased according to the setting condition. There is an effect that the recorded program can be managed.

  In addition, since the reservation erasure is performed immediately before the reservation recording, the user does not need to consider the date and time for erasing the content data one by one, and the troublesomeness when setting the reservation erasure is reduced. Even if you want to stop erasing content data unexpectedly, the next content data will not be erased until immediately before the scheduled recording operation. good.

  Also, you can select the reservation erasure condition from several options, such as when the remaining capacity of the disc recording medium is insufficient, when there is content data that has been played, weekly, daily, Monday to Friday, Monday to Saturday, etc. Therefore, it is possible to delete the reservation of the content data according to the conditions desired by the user.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the disk recording medium includes various types of media such as an optical disk for blue-violet laser, a magnetic optical disk, and a hard disk that can be inserted into and removed from the apparatus, in addition to DVD. In addition to the conditions exemplified in the embodiment, various conditions may be applied as conditions for performing reservation erasure, and a plurality of conditions may be selected together.

  Also, the configuration is shown in which the reservation erasure is performed immediately before the recording reservation, but this time can be specified by the user, or it can be set at a timing unrelated to the recording reservation time such as midnight. good.

  In addition, the details specifically shown in the embodiment, such as the internal configuration of the disk recording device, the contents of the reservation recording setting screen, and the procedure of each processing, can be changed as appropriate without departing from the spirit of the invention. .
