Description

  The present invention relates to an optical disk apparatus that records on an optical disk such as a DVD, and more particularly to an optical disk apparatus that displays a list of types of optical disks that can be recorded.

  One of the devices for recording a program to be recorded on a DVD using a recording reservation is the following device (referred to as a first conventional technology). That is, in this apparatus, the recording reservation input means (timer reservation means), the first detection means for detecting that the recording disc is a recordable medium, and the optical focus on the disc are defined. Second detection means for detecting that the disk is within the range and third detection means for detecting that the disk is in a rotatable state are provided. When it is found that even one of the detection results of the first to third detection means does not correspond, it is determined that the recording is not possible, and the user is warned that the timer reservation cannot be made. (For example, refer to Patent Document 1).

  In addition, when an instruction to record a program being received is input when a program is being received, the DVD stored in the DVD drive is a reproduction-only DVD and a DVD that cannot be recorded. There has also been proposed a device that displays a message indicating that recording cannot be performed because the DVD is dedicated for reproduction, and moves the DVD stored in the DVD drive to the take-out position (second conventional technique).

Further, the following technique has been proposed (referred to as a third conventional technique). That is, this technology is applied to a configuration in which compressed video information can be recorded and reproduced on a built-in hard disk drive, and compressed video information can be recorded and reproduced on a removable DVD. Then, the scheduled recording time information and the remaining capacity of the disk are calculated to display a list of whether or not the scheduled recording is possible. For this reason, it is possible for the user to easily know the status of reservation and whether or not reservation recording is possible (see, for example, Patent Document 2).

Further, at this time, when the change of the recorded content after the recording is selected is selected as the change, the list to be displayed is a list obtained by deleting the DVD that cannot be rewritten from the list of all types of the DVD. And

  The disc information display means 19 dubbes the program specified by the dubbing program specifying means 18 when it is requested to display information on the DVD that can be used for dubbing the program specified by the dubbing program specifying means 18. A list of all types of DVDs that can be displayed. When there are a plurality of programs designated by the dubbing program designation means 18, a list of all types of DVDs that can be recorded for all the designated programs is displayed. In addition, when “changed” is selected in the selection of whether or not the recorded content is changed after dubbing, the list to be displayed is a list in which DVDs that cannot be rewritten are deleted from the list of all types of DVDs.

  FIG. 3 is a flowchart showing the main operation of the embodiment when displaying a list of DVDs that can be used for recording by recording reservation. The operation of the embodiment will be described with reference to FIG.

  By operating the remote controller 23 and displaying the recording reservation input screen shown in FIG. 4, the recording reservation is input (step S1). Assume that two recording reservations are input as shown in FIG. In this state, when the “display list” button 41 is operated to display a list of usable DVDs (step S2), the disc information display means 19 records on the DVD (“DVD1”) corresponding to the cursor 491. The recording reservation to be extracted is extracted. At this time, only the recording reservation of reservation number 1 is extracted (step S3).

  Then, the disc information display means 19 considers that no change has been selected in the selection of whether or not to change the recorded content after recording, and can be used for the extracted recording reservation (recording reservation of reservation number 1). Is displayed (steps S4 to S6). Accordingly, when the operation shifts to step S6, as shown in FIG. 5A, a list of all types of DVDs that can be used for the recording reservation where the cursor 491 is located (recording reservation whose reservation number is 1) is displayed. Is displayed. Note that since the recording reservation program with reservation number 1 is a program with no copy restriction, all types of DVDs that can be recorded using this embodiment are displayed. In addition, in the display of a list of all types of DVDs (“all types” in the following description means all types of DVDs that can be used in the present embodiment), it is used because it is inexpensive. A recommendation mark “**” 451 is displayed for the recommended DVD.

  At this time, the total recording capacity of the extracted recording reservations is smaller than the recordable capacity, which is a value that can be recorded on one DVD. For this reason, operation | movement transfers to step S7-S9, S13 after step S17. Then, whether or not “change” is changed to “change” or “change” is changed to “no change” in the selection of whether or not the recorded content is changed after recording (steps S13 and S14). Then, the process proceeds to a loop operation for checking whether the cursor 491 has moved (step S15) and whether to end the list display (step S16).

  The “edit / rewrite” button 43 in FIG. 5A is a button for selecting “with change” in the selection of whether or not to change the recorded content after recording, and the “for saving” button 44 is for recording. In the later selection of whether or not the recorded content has been changed, this button is used to select “no change”. Therefore, when the “edit / rewrite” button 43 is operated in the state shown in FIG. 5A, the loop operation shifts from step S14 to step S4.

  At this time, since there is “change”, the operation shifts to steps S5 and S17. As a result, as shown in FIG. 5B, a list of DVD types from which DVDs that cannot be rewritten are deleted from the list of all types of DVDs when the “save” button 44 is operated is displayed. . At this time, a recommendation mark “**” 452 is displayed for “DVD-RW”. Next, after proceeding to steps S7 to S9 and S13, the process proceeds to a loop operation comprising steps S13 to S16.

  It is assumed that the cursor 491 is moved to the recording reservation of reservation number 2 in the loop operation composed of steps S13 to S16. At this time, the operation proceeds from step S15 to step S3, and a recording reservation to be recorded on “DVD2” is extracted. At this time, only the recording reservation of reservation number 2 is extracted (step S3). Then, the disc information display means 19 considers that “no change” is selected in the selection of whether or not the recorded content has been changed after recording. For this reason, the disc information display means 19 is the type of DVD that can not be rewritten (all types of DVDs that can be recorded in this embodiment) among the DVDs that can be used for the extracted recording reservation (recording reservation of reservation number 2). A list is displayed (steps S4 to S6).

  As a result, the content shown in FIG. 6A is displayed on the television receiver 22 (the cursor after movement is indicated by 492). That is, the recording reservation with reservation number 2 is a reservation for recording a copy-once program. For this reason, the displayed list is a list of all types of DVDs compatible with copy once. When the “edit / rewrite” button 43 is operated in the state shown in FIG. 6A, the display shown in FIG. That is, a list in which DVDs that cannot be rewritten are deleted from a list showing all DVDs that support copy once.

  Now, the description of the operation when two recording reservations are input ends, and the operation when more recording reservations are input will be described below.

  Now, as shown in FIG. 7A, it is assumed that seven recording reservations are input. Further, it is assumed that the cursor is positioned at the recording reservation of reservation number 1 as indicated by 493. Also, it is assumed that an instruction to display a list of usable DVDs is input (steps S1 and S2). At this time, the disc information display means 19 extracts a recording reservation to be recorded on the DVD (“DVD1”) corresponding to the cursor 493. As a result, four recording reservations with reservation numbers 1, 3, and 4 are extracted (step S3).

  Further, the disc information display means 19 considers that “no change” has been selected in the selection of whether or not the recorded content has been changed after recording. Then, a list of usable DVDs is displayed for all of the extracted recording reservations (recording reservations of reservation numbers 1, 3, and 4) (steps S4 to S6). At this time, the program with reservation numbers 1 and 3 has no copy restriction, but the program with reservation number 4 is copy-once. For this reason, the list of DVD types displayed on the television receiver 22 is a list of all types of DVDs capable of recording copy-once programs as shown in FIG. Shown).

  Thereafter, the total value of the recording capacities of the extracted recording reservations is calculated, and it is checked whether the calculation result is a recordable value (whether the calculation result is less than the recordable capacity) (steps S7 and S8). At this time, the total value of the recording capacity is 3 hours in terms of the SP mode (2 hours in the SP mode and 4 hours in the LP mode can be recorded on one DVD). That is, the calculation result indicates that recording cannot be performed on one DVD.

  For this reason, the operation shifts to steps S9 and S10, and the disc information display means 19 displays a message (indicated by 48) indicating that the total recording capacity exceeds the value recordable on the DVD. In addition, the bit rate that provides the highest image quality within a range where the recording capacity does not exceed the recordable capacity of the DVD when all the programs reserved for recording (three programs of reservation numbers 1, 3, and 4) are recorded on the DVD is set. An “automatic” button 45 for instructing to automatically calculate and record, and an “as is” button 46 to instruct to record in the designated recording mode are displayed.

  In the state shown in FIG. 7A, when the “Random” button 45 is operated, the bit is set so that the total recording capacity can be recorded on the DVD and the highest image quality is obtained. The rate calculation means 15 calculates a bit rate that enables recording of three programs with reservation numbers 1, 3, and 4. Then, the recording mode is changed based on the calculation result. Therefore, when the “Random” button 45 is operated, the display on the television receiver 22 is the display shown in FIG. That is, the recording modes of the two programs with reservation numbers 1 and 3 are changed from SP to LP. Therefore, recording is performed for 4 hours in the LP mode. That is, three programs are recorded with the highest image quality on one DVD.

  When the “edit / rewrite” button 43 is operated in the state shown in FIG. 7A, the display on the television receiver 22 becomes the display shown in FIG. That is, a list of DVDs that cannot be rewritten from the list of DVDs that can record copy-once programs is displayed.

  In addition, when the cursor is moved to the recording reservation of reservation number 2, the recording capacity of the program recorded on “DVD2” (programs according to program numbers 2 and 6) is equal to the recordable capacity. Accordingly, at this time, the display on the television receiver 22 is the display shown in FIG. 9A (it is considered that the “save” button 44 has been operated). A list of all types is displayed. When the “edit / rewrite” button 43 is operated, as shown in FIG. 9B, a list of DVDs that cannot be rewritten is displayed from the list of DVDs that can record copy-once programs. The

  FIG. 10 is a flowchart showing the main operation of the embodiment when displaying a list of DVDs that can record the program being received. The operation of the embodiment will be described with reference to FIG.

  By operating the remote controller 23 or the like, the program received by the tuner unit 1 is displayed on the television receiver 22 (step S31). In this state, for example, by operating a list display key provided on the remote controller 23 (not shown, consisting of a key switch or the like added to input a list display instruction), a program being received To display a list of recordable DVDs (step S32).

  When a list display instruction is input, the disc information display means 19 checks the type of DVD that can record the program being received. At this time, the program being received is a copy-once program (mainly when digital broadcasting is received) by referring to EPG or the like, or a program without copy restrictions (mainly analog). (If a broadcast is received), the type of recordable DVD is acquired) (step S33).

  Then, the information shown in FIG. 11A is superimposed and displayed on the image of the program being received. That is, in the selection of whether or not the recorded content is changed after recording, an “edit / rewrite” button 51 operated when “changed” is selected, and “changed” is operated when “no change” is selected. The “save” button 52 is displayed (step S34). Further, it is assumed that the “save” button 52 has been operated, and a list of types of DVDs that can be recorded (including DVDs that cannot be rewritten) is displayed. At this time, in order to recommend the use of the cheapest DVD-R, a recommendation mark “**” 581 is displayed on the displayed DVD-R (steps S35 to S37).

  Thereafter, the process proceeds to a loop operation for checking whether the “edit / rewrite” button 51 is operated or whether the end button (not shown) is operated (steps S38 to S40). In this state, when the “edit / rewrite” button 51 is operated, as shown in FIG. 11B, among all types of DVDs capable of recording the program being received, the DVDs that cannot be rewritten are deleted. The completed list is displayed (steps S35, S36, S41).

  In the figure, the program being received is a program with no copy restriction. Therefore, when the program being received is copy-once, the list of all types of DVD displayed in FIG. 4A is DVD-R / CPRM compatible, DVD-RW / CPRM compatible, and DVD-RAM. In FIG. 5B, the list is DVD-RW / CPRM compatible and DVD-RAM. When the “end display” button 53 is operated, the list display operation is ended.

  FIG. 12 is a flowchart showing the main operation of the embodiment when displaying a list of DVDs that can be used when dubbing. The operation of the embodiment will be described with reference to FIG.

  Now, it is assumed that the program shown in FIG. 13 is recorded on the HDD 6 (other programs are also recorded on the HDD 6, but the other programs are not shown). In this state, the remote controller 23 is operated to specify a program to be dubbed (step S51). Now, as shown in FIG. 13, it is assumed that the program with program number 2 is designated. Then, an instruction to display a usable DVD is input (as an input method, for example, a method of operating a “list display” button 41 as shown in FIG. 4) can be used (step S52).

  The disc information display means 19 considers that no change has been selected in the selection of whether there is a change in the recorded content after dubbing (again, used to record another program) or no change (permanent storage), A list of all types of DVDs that can be used for dubbing the designated program is displayed (steps S53 to S55). Therefore, when the operation shifts to step S55, as shown in FIG. 13A, when a program indicated to be dubbed by the cursor 691 is dubbed to the DVD 21, a list of all types of DVDs that can be used. Is displayed.

  Note that the program specified by the cursor 691 is a terrestrial analog broadcast, and thus is a program with no copy restrictions. Accordingly, at this time, all types of DVDs that can be recorded using this embodiment are displayed. Further, in the display of the list of DVD types, a recommendation mark “**” 651 is displayed for the recommended DVD.

  After this, in the selection of whether or not the recorded content has been changed after dubbing, whether “No change” has changed to “With change” or “Changed” has changed to “No change” (step) S56, S57), whether or not the program designated as the dubbing target has been changed (step S58), and whether or not to end the display (step S59), the process proceeds to a loop operation.

  When the “rewrite” button 61 is operated in the state shown in FIG. 13A, the operation shifts from the loop operation consisting of steps S56 to S59 to step S53. At this time, since there is “change”, the operation shifts to steps S53, S54, and S60. For this reason, as shown in FIG. 13B, a list of DVD types from which DVDs that cannot be rewritten are deleted from the list of all types of DVDs when the “save” button 44 is operated is displayed. . At this time, a recommendation mark “**” 652 is displayed for “DVD-RW”. Thereafter, the process proceeds to a loop operation consisting of steps S56 to S59.

  Further, in the state shown in FIG. 13A, that is, in the state where the program number 2 is designated as the dubbing target, it is further designated that the program number 1 program is also dubbed simultaneously ( This designation is indicated by the cursor 692), that is, when it is instructed to dubb the two programs of the program number 1 and the program number 2 onto the DVD 21, the operation is performed from step S58 to step S53. And migrate. At this time, since the “save” button 44 is operated, the operation shifts to steps S53 to S55.

  In step S55, as shown in D14 (A), the disc information display means 19 can be used for dubbing all types of DVDs that can be used for dubbing programs with program number 1 and programs with program number 2. A list showing only the types of DVDs that are common to both types of DVDs is displayed. That is, the program of program number 2 is a terrestrial analog broadcast and is a copy-free program, while the program of program number 1 is a copy-once for terrestrial digital broadcasting. For this reason, the displayed list is a list of all types of DVDs that can record copy-once programs. In this state, when the “rewrite” button 61 is operated, the displayed list deletes DVDs that cannot be rewritten from the list shown in FIG. 14A, as shown in FIG. It becomes a list.
