Description

  The present invention relates to an optical disc recording / reproducing apparatus for recording / reproducing a television program and other information on an optical disc, and more particularly to a display function of a recording reservation list screen.

  In recent years, DVDs (digital versatile discs), which are optical discs capable of recording information such as a large amount of video and audio data such as movies, have become widespread. As types of DVDs, a DVD-ROM in which information is recorded on the manufacturer side and cannot be rewritten on the user side, a DVD-R or DVD + R on which information can be recorded only once on the user side, and a DVD that can be rewritten several times on the user side. -RW, DVD + RW, DVD-RAM, etc. are known. Information recorded on these DVDs can be played back by an optical disk playback device (DVD player) or an optical disk recording / playback device (DVD recorder), and can be recorded on DVD-R, DVD + R, DVD-RW, DVD + RW, and DVD-RAM. Information can be recorded by an optical disk recording / reproducing apparatus (DVD recorder).

By the way, a rewritable DVD such as DVD-RW, DVD + RW, or DVD-RAM is often used to record a television program. Since the storage capacity of a DVD is 4.7 GB, the number of TV programs that can be recorded on each DVD is not so large. Therefore, when a TV program to be recorded is recorded on a DVD, the available capacity of the DVD is checked in order to check whether the TV program can be recorded on the DVD currently inserted in the apparatus.

  2 to 5 are diagrams showing examples of the contents of the recording reservation list screen in the present embodiment.

  First, FIG. 2 shows that when the currently inserted DVD is not a recordable DVD or when there is no free space, the display of the cursor areas C1, C2, C3 for reservation of all TV programs is the same color, for example, It is a video recording reservation list screen which shows the state currently displayed on black. Such a black display indicates that the currently inserted DVD is not a recordable DVD or a DVD with no free space, and prompts the user to replace the recordable DVD.

  FIG. 3 shows the display of the cursor areas C1, C2 and C3 for the reservation of the remaining TV programs other than the reservation of the TV program that can be recorded with the currently inserted DVD, and is color-coded by the specified capacity (4.7 GB) of each DVD. It is a recording reservation list screen displayed. The display color of the reserved cursor area C1 is, for example, blue, the display color of the reserved cursor area C2 is, for example, red, and the display color of the reserved cursor area C3 is, for example, green. Each is color-coded. By such color coding, it can be seen that the recording by the recording reservation other than the reservation that can be recorded by the currently inserted DVD must be exchanged with another DVD.

  FIG. 4 is a recording reservation list screen showing a case where the recording reservation on January 3 is changed to another DVD. In FIG. 4, TV programs that are recorded with channel CH 8 channels, date January 1 (every Monday), recording start time AM 10:00, recording end time AM 11:00, and recording mode SP are weekly. It shows that it will be recorded on Monday. For television programs that are repeatedly scheduled for recording, such as every week, every day, a color is set in the cursor area at the first recording start time (for example, AM 10:00). The display color of the reserved cursor area C1 is, for example, blue, and the display color of the reserved cursor area C2 and the cursor area C3 is, for example, red. By such color coding, it can be seen that from the television program scheduled for recording on January 3, it must be recorded on another DVD that is not currently inserted.

  For a television program that is scheduled to be repeatedly recorded every week or every day, the repetition is considered as a plurality of recording reservations. For example, when a certain TV program starting on January 1 is recorded every week (also recorded on January 8 of the next week), recording reservation for January 3 and recording reservation for January 10 are registered. Recording start order is January 1 (every Monday), January 3, January 8 (every Monday), January 10, January 15 (every Monday), January 22 (every week) As shown in FIG. 4, the display color of the reserved cursor area C1 is, for example, blue, as shown in FIG. Thus, the display color of the reserved cursor area C2 and cursor area C3 is, for example, red.

  FIG. 5 is a recording reservation list screen showing a case where the recording reservation on January 10 is changed to another DVD. In FIG. 5, the display color of the reserved cursor area C1 and the cursor area C2 is, for example, blue, and the display color of the reserved cursor area C3 is, for example, red. By performing such color coding, it is understood that from a television program scheduled for recording on January 10, it is necessary to record on another DVD that is not currently inserted.

  FIG. 6 is a flowchart for explaining processing for setting the display color of the cursor area indicating the contents of the recording reservation on the recording reservation list screen displayed when the recording reservation is performed in the present embodiment. A process for setting the display color of the cursor area indicating the content of the recording reservation on the recording reservation list screen displayed when the recording reservation is performed will be described with reference to this flowchart and FIGS.

  First, the user operates the remote controller 21 to display the recording reservation list screen on the display device 20. Here, the user operates the remote controller 21 to register a recording reservation for a desired television program on the recording reservation list screen. As a result, the system controller 22 detects that an instruction to register a recording reservation has been given (step S1), and the CPU 24 processes the recording reservation information (channel, date, recording start time, recording end time). , Recording mode).

  Then, the system controller 22 determines whether or not there is a recording reservation by accessing the flash ROM 23 by the processing of the CPU 24 and checking whether or not recording reservation information is registered in the flash ROM 23 (step S22). S3) If there is no recording reservation information registered in step S2, there is no recording reservation. Therefore, when it is determined that there is no recording reservation, this process ends.

  On the other hand, if there is a recording reservation information registration process in step S2, there is a recording reservation. Therefore, when it is determined that a recording reservation exists, the system controller 22 determines that the DVD is inserted. By reading the disc management information, it is determined whether or not a recordable DVD is inserted (step S4).

  When it is determined that a recordable DVD is not inserted, that is, when the inserted DVD is not a recordable DVD, or when a recordable DVD has no free space (remaining capacity), The first display processing means of the system controller 22 displays the cursor areas C1, C2, C3 indicating the contents of all the recording reservations displayed on the recording reservation list screen (see FIG. 2), for example, in black (step S9). ).

  When it is determined that a DVD having a free space that can be recorded is inserted, the second display processing means of the system controller 22 changes from the first recording reservation displayed on the recording reservation list screen to the current free space state. The cursor area indicating the contents of the recording reservation that can be recorded is displayed in the same color (step S5). That is, the second display processing means records each of the recording reservations from the recording time (time obtained by subtracting the recording start time from the recording end time) and the recording mode indicated by the information of the first recording reservation displayed on the recording reservation list screen. By calculating each recording capacity required for recording the television program and referring to each recording capacity, a cursor area indicating the contents of the recording reservation for the TV program that can be recorded on the DVD, for example, in FIG. The cursor areas C1 and C2 shown are displayed in the same color.

  Further, the third display processing means of the system controller 22 displays the remaining reservations in the same color in an amount that can be recorded on each DVD (step S6). In other words, the third display processing means has a recording reservation list screen (see FIG. 3) for the cursor area indicating the contents of the recording reservation of the remaining TV programs other than the recording reservation of the TV program that can be recorded with the currently inserted DVD. ), The specified capacity (for example, 4.7 GB) of each DVD is color-coded and displayed (step S6).

  Thereafter, the system controller 22 determines whether or not the recording is started and ended according to the recording reservation information registered in the flash ROM 23 (step S7). If it is determined that the recording is started and ended, the recording is performed. The reserved reservation (information of the corresponding recording reservation registered in the flash ROM 23) is deleted (step S8), and the process returns to step S3. On the other hand, if it is determined that the recording is not started and ended, step S1 is executed. Return to the process.

  As described above, according to the present embodiment, the user knows that recording is not possible with the currently inserted DVD, knows the TV program that can be recorded with the currently inserted DVD, and replaces the next DVD. It is possible to know in advance the time and the next DVD replacement time, and therefore, it is possible to save the trouble of confirming the capacity of the DVD and to prevent a recording failure.

  The present invention can be used for a display function of a recording reservation list screen of a DVD recorder, and the replacement time of a DVD can be grasped at a glance.
