A digital conversion unit 3 that converts a broadcast signal extracted by the tuner 2 into a digital signal in accordance with a predetermined encoding method, an encoder that encodes the digital signal converted and output by the digital conversion unit 3 and outputs the digital signal as digital data 4. The digital data output from the encoder 4 is recorded, the HDD (Hard Disk Drive) 5 capable of holding the recorded contents even when the power supply is cut off, and the writing / reading controlling the writing and reading of the digital data to the HDD 5 The controller 6 inputs the digital data read from the HDD 5 and decodes it. The decoder 7 that outputs a digital signal, the analog signal 8 that is input from the digital signal output from the decoder 7 and converted into an analog signal, and the analog signal that is output from the analog converter 8 are input to the video. And an output unit 9 such as a TV receiver for outputting as a voice or the like.

  Further, the recording / reproducing apparatus of FIG. 1 is a CPU (abbreviation of 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 writing / reading control unit 6. 10. ROM (Read Only Memory) 11 and RAM (Random Access Memory) 12 for storing information (program, data, etc.) for the CPU 10 to control them, and an external remote controller (abbreviation of remote controller) 14 includes an input unit 13 and an OSD (on screen display) circuit 15 that receive an instruction by an infrared signal from 14, convert it into data, and supply the data to the CPU 10.

  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 receives the drawing data, it converts the data read from the HDD 5 and given through the decoder 7 into analog data and outputs it to the output unit 9. The moving image (or still image) read from the HDD 5 is displayed on the base screen.

  When the command from the remote controller 14 is not input, the input unit 13 may be configured with various switches, buttons, and the like that are operated by a user for inputting a command from the outside.

  The remote controller 14 includes a numeric keypad 140 for channel designation and the like operated by the user from the outside, a delete button 141, a determination button 142, a cursor key 143, and a skip button 144 described later. The cursor key 143 includes a key for moving a point such as a cursor displayed on the output unit 9 in each of the up, down, left, and right directions.

  Note that writing (recording) / reading (reproduction) of information on the disk of the HDD 5 is performed via the read / write control unit 6 under the control of the CPU 10.

  2A to 2D show the format of data in the disk of the HDD 5. As shown in FIG. 2A, an area E1 and an area E2 are provided on the disk of the HDD 5 in advance. The areas E1 and E2 are different storage areas.

  Referring to FIG. 2A, area E1 has a system block SB in which information for collectively managing data recorded in area E2 is recorded. Area E2 has a plurality of fixed lengths. It has data blocks DBi (i = 1, 2, 3,..., N).

  Referring to FIG. 2B, the system block SB has a plurality of management information Pj (j = 1, 2, 3,..., M) and a mapping table MPT. The management information Pj is a block composed of one or more data blocks DBj constituting each program when a large amount of data recorded in the plurality of data blocks DBi in the area E2 is divided into units of a predetermined size, for example, different program units. A program corresponding to index data IDj (j = 1, 2, 3,..., M) that is provided corresponding to a group and specifies a block group, that is, a program recorded in the block group. Head block information HEDj (j = 1, 2, 3,...) For indicating in the area E2 the data block DBi in which the head (first) data is recorded among one or more data blocks DBi constituting the data of .., M) and valid / invalid data APj (j = 1, 2, 3,..., N) are associated with each other. The valid / invalid data APj will be described later.

  Referring to FIG. 2C, the data block DBi includes data 21 indicating the previous data position of the data block DBi, data 22 indicating the next data position, data 23 indicating the start time, data 24 indicating the end time, Program image, audio recording data 25, index time data ITk (k = 1, 2, 3,..., P) and offset data OFk (k = 1, 2, 3,. .., P), and an area for storing a deletion start index IDS and a deletion end index IDE.

  When the program is composed of a plurality of data blocks DBi, the plurality of data blocks DBi are accessed in accordance with the recording order or reproduction order of the program information. The data 21 indicates a recording position (address) in the area E2 of the data block DBi accessed immediately before the data block DBi among the plurality of data blocks DBi sequentially accessed in this way. Similarly, the data 22 indicates a recording position (address) in the area E2 of the data block DBi accessed next. If there is no previous or next data block DBi, the data 21 or 22 indicates that the corresponding data block DBi does not exist.

  Data 23 and 24 indicate recording start and end times for the recording data 25 of the data block DBi, respectively. The index time data ITk specifies each of a plurality of scenes constituting the recording data 25, and the offset data OFk indicates how many bytes from the beginning of the recording data 25 the recording of each data of the plurality of scenes is started.

  The deletion start index IDS and the deletion end index IDE indicate index time data ITk for a start scene and an end scene corresponding to or related to a period in which deletion is instructed. The deletion start index IDS and the deletion end index IDE instruct to omit the reproduction of a series of data recorded between the start scene and the end scene corresponding to the deletion instructed period. Further, since the index time data ITk is registered as a pair with the corresponding offset data OFk, the corresponding offset data OFk is determined by the deletion start index IDS and the deletion end index IDE that respectively indicate the index time data ITk. It can be uniquely identified. Therefore, the deletion start index IDS and the deletion end index IDE indicate a recording area in the series of data HDD 5 recorded between the start scene and the end scene corresponding to the period in which the deletion is instructed.

  FIG. 2D shows an example of the contents of the mapping table MPT in FIG. In the mapping table MPT, information indicating whether or not each of the plurality of data blocks DBi in the area E2 has an area where new data can be written is registered correspondingly. Specifically, if all the data blocks DBi are used for data recording, the used data UF is all unused data AUF if all are unused, and partly unused if some are not used. Data PUF is registered in association with each other. New data can be written into the data block DBi corresponding to all unused data AUF (writing is permitted).

(Embodiment 1)
Here, regarding the program data recorded in the HDD 5, an operation for instructing the user to delete data corresponding to a desired scene while monitoring the video of the program will be described.

  FIGS. 3A and 3B schematically show the deletion procedure according to the first embodiment. As shown in FIG. 3A, when information of an unnecessary (unwanted) part such as a CM is recorded or played back during recording or playback of the recorded program, the user touches the delete button 141 with one touch. Operate and press (time T1). In the recording / reproducing apparatus of FIG. 1, recording or reproduction is continued as usual even after the delete button 141 is pressed. Next, when the scene is to be avoided (desired to be recorded / reproduced) due to the end of the CM or the like, the user again presses the delete button 141 with a one-touch operation (time T2). The apparatus in FIG. 1 determines that the section (time T1 to T2) in which the delete button 141 is pressed is a part to be deleted. Data determined to be deleted is skipped (read skipped) the next time the program is played back (see FIG. 3B). As a result, the information of the part that the user desires to delete is skipped in the subsequent reproduction process if the deletion operation as shown in FIG. The deleted area (data block DBi) can be used for recording another program.

(Operation during recording)
Next, according to the flowchart of FIG. 4, the operation accompanied by the deletion operation by the user at the time of recording in the apparatus of FIG. It is assumed that the program according to the flowchart of FIG. 4 is recorded in the ROM 11 in advance.

  First, in order to record a desired program, the user inputs information on a channel that broadcasts the desired program, information on a broadcast time (start and end) of the program, and the like via the remote controller 14. When the CPU 10 detects that the input broadcast start time is reached, the CPU 10 starts the recording operation as follows. It is assumed that a variable for counting the number of times the delete button described later is reset to 0 or the like every time processing is started.

  First, since the CPU 10 controls the tuner 2 to extract a broadcast signal of a channel that broadcasts a desired program based on input information, the broadcasting is performed via the antenna 1, the tuner 2, the digital conversion unit 3, and the encoder 4. Time-series data is derived according to the broadcast time of the desired program.

  The CPU 10 searches the mapping table MPT of the system block SB of the HDD 5, specifies the data block DBi whose usage information indicates all unused data AUF (empty block), and stores all the usage information corresponding to the specified data block DBi. The usage data UF is updated (step S (hereinafter simply referred to as S) 20). Thereafter, the index data IDi and head block information HEDi of the system block SB are recorded. Specifically, the data specifying the desired program is written in the index data IDi, and the data specifying the data block DBi specified in S20 is written in the head block information HEDi (S21).

  Next, the CPU 10 writes the start time of the desired program in the data 24 of the data block SBi, and the data 21 of the data block DB (i−1) in which the data 25 for the desired program is recorded immediately before ( S22). Since the data block DB (i-1) in which the immediately preceding data 25 is recorded does not yet exist at the start of recording of the program, nothing is written in the data 21 or empty data “NULL” is written in this case. Is included. Next, the image / sound data derived for the desired program is recorded as data 25 in the data block DBi (S23).

  Here, in the apparatus of FIG. 1, the data being recorded on the HDD 5 in parallel with the recording of the program is read on the spot, and the image (video) / audio is output to the output unit 9 via the decoder 3 and the analog conversion unit 8. Is output as Accordingly, when the user confirms the information (image / sound) of the part desired to be deleted while monitoring the output content of the output unit 9, the user can operate the delete button 141 to display the part information (image / sound). Can be specified to be deleted.

  The CPU 10 detects whether or not the user presses the delete button 141 (S24). If the pressing is not detected (NO in S24), the process proceeds to S25 and later. When a press is detected, the value of the variable that counts the number of times the delete button is pressed is incremented by 1 (YES in S24). Based on the variable, it indicates the first press (value is 1) or the second press is performed. Whether it is indicated (value is 2) is determined (S31). If it is the first press (the first time in S31), it is a press for designating the start position of the partial information desired to be deleted, so the deletion start index IDS is recorded in the currently recorded data block DBi ( The process proceeds to S32) and S25.

  If it is the second press (second time in S31), it is a press for designating the end position of the partial information desired to be deleted, so the deletion end index IDE is recorded in the currently recorded data block DBi. (S33). Then, the value of the variable for counting the number of times the delete button is pressed is reset (S34), and the process proceeds to S25.

  Here, for the sake of simplicity, it is assumed that one set of deletion start index IDS and deletion end index IDE is recorded for each block DBi.

  Thereafter, whether or not the recording has ended is determined based on whether or not the broadcast end time of the program has come, whether or not the broadcast end code of the program has been received and recorded (S25).

  If it is determined that recording is to be ended (YES in S25), a series of recording operations are ended. If not (NO in S25), whether or not writing of data 25 for the data block DBi is to be ended is determined. It is determined (S26). For example, if the data 25 is written to the end of the data block DBi and no more data can be written, it is determined that the writing has been completed, and otherwise, it is determined that the writing has not been completed.

  While it is not determined that the writing is completed, a series of processes of S23 to S26 and S31 to S34 are repeated. When it is determined that the writing has been completed, an end code (not shown) is recorded at the end of the data 25 of the data block DBi and an end time is written in the data 24 (S27). Thereafter, in order to record the data 25 in the next data block DB (i + 1), the mapping table MPT of the system block SB is searched, and the free data block DB (i + 1) whose use information indicates all unused data AUF is specified. Then, the usage information of the identified data block DB (i + 1) is updated to usage data UF (S28).

  Then, data specifying the next data block DB (i + 1) specified in S28 is written as data 22 of the previous data block DBi (S29).

  Then, for the specified next data block DB (i + 1), the data 23 is written with the data 25 recording start time and the data 21 is specified with the data block DBi (S22). Thereafter, data 25 is similarly written to the next data block DB (i + 1) in the processing from S23.

  If it is determined that the recording operation is ended (YES in S25), the CPU 10 determines whether or not the deletion start index IDS and the deletion end index IDE are set for each data block DBi accessed for the current recording. If there is a set data block DBi, the following processing is performed (S30).

  If the information indicated by the indexes IDS and IDE indicates the beginning and end of the data 25 of the data block DBi, the data block DBi itself is targeted for deletion, and therefore the data block DBi immediately before the data block DBi. The data 22 is updated using the data 22 of the data block DBi. If the deletion start index IDS and the deletion end index IDE indicate the deletion of the partial data of the data 25 of the data block DBi, the usage information of the data block DBi is updated to the partially unused data PUF.

  After that, since the deletion start index IDS and the deletion end index IDE are set, it is shown that the specification of the deletion point is set to be valid for the valid / invalid data APj of the management information Pj corresponding to the data block DBi. Rewrite “valid”.

  As described above, in the recording operation, the recorded data is monitored by the output unit 9 and the partial information desired to be deleted is simply deleted by operating the delete button 141 twice at the start time and the end time. Can be specified uniquely.

  Also, since the usage information of the data block DBi corresponding to the data instructed to be deleted is updated to all unused data AUF at the end of the recording operation, the recording area (data overwriting is permitted in the subsequent recording operation of the program) Area).

(About playback operation)
An operation involving a deletion operation by the user at the time of reproduction of the apparatus of FIG. 1 will be described according to the flowchart of FIG. It is assumed that the program according to the flowchart of FIG. Further, it is assumed that the deletion start index IDS and the deletion end index IDE are not set for each data block DBi.

  First, when a desired program is designated out of program information prerecorded on the disk of the HDD 5 and an instruction to reproduce the desired program information is input via the controller 14, the CPU 10 The playback of the desired program is started.

  First, the system block SB is accessed to specify the index data IDj corresponding to the designated desired program in the system block SB of the HDD 5, and the head block information HEDj corresponding to the specified index data IDj is searched (S1). . Then, the data block is accessed as follows.

  The data block DBi in the area E2 indicated by the searched head block information HEj is specified, and the index time data ITk of the specified data block DBi is read (S2). Necessary data based on the read index time data ITk It is determined whether or not there is (S3).

  For example, when a specific scene such as a scene desired to be reproduced is instructed via the controller 14, whether or not the index time data ITk corresponding to the instructed scene is included in the read index time data ITk. Determine. If it is included, it is determined that there is necessary data, and if not, the process proceeds to S7 described later.

  If a specific scene is not instructed, it is determined that there is necessary data.

  In the process of S3, if it is determined that there is necessary data (YES in S3), the data 25 of the data block DBi is read (S4).

  The data 25 is read from the data 25 based on the offset data OFk corresponding to the index time data ITk corresponding to the necessary scene data determined in S3. In particular, when no scene is designated, all data 25 is read out. The image (video) / sound by the data read out in this way is output to the monitor via the output unit 9. When the user confirms the information (image / sound) of the part desired to be deleted while checking the program to be played back, the user presses the delete button 141 at the deletion start time (time T1 in FIG. The deletion part can be designated by operating twice at time T2) in FIG. 3 (S5, S9 to S12). Since this processing is the same as the processing of S24 and S31 to S34 described in FIG.

  Thereafter, reading of data 25 (S4) is repeated until reading of data 25 from the data block DBi is completed (YES in S6). The end of reading of the data 25 is determined by reproduction of the data 25, a determination based on a terminal code (not shown) in the data 25, a determination according to detection of zero data, or a program broadcast end time. Or

  When the reading of data from the data block DBi is completed (YES in S6), the data 22 of the data block DBi is read, and it is determined whether there is a next data block DBi based on the read data 22 (S7). If the data 22 indicates that the next data block DBi does not exist (NO in S7), the process of S13 is executed. The process of S13 is the same as the process described in S30 of FIG.

  If the data 22 indicates the position (address) of the next data block DBi (YES in S7), the next data block DB (i + 1) in the area E2 is searched based on the indicated position (address). Then, the index time data ITk of the retrieved data block DB (i + 1) is read (S8). Thereafter, the process returns to step S3, and thereafter the necessary data 25 is read from the data block DB (i + 1) in the same manner.

  In this way, by repeating the reproduction process for each data block DBi, the data 25 is read from each of the data blocks DBi constituting the desired program and reproduced and output.

  The user can delete the partial information desired to be deleted while monitoring the data read and reproduced as described above by operating the delete button 141 twice at the start time and the end time. Can be specified uniquely.

(Embodiment 2)
In the present embodiment, the reproduction procedure after the deletion point setting by the user operation of the first embodiment is shown.

  The program playback procedure when the program to be played back includes a program in which the deletion point indicated by the deletion start index IDS and the deletion end index IDE is specified according to the procedure of FIG. 4 or FIG. A description will be given according to the flowchart. It is assumed that the program according to the flowchart of FIG. 6 is recorded in the ROM 11 in advance.

  In FIG. 6, when the reproduction of the desired program is started, the processes of S1 to S3 and S4 to S8 are executed in the same manner as in FIG.

  It is determined whether or not the deletion start index IDS is detected for each data block DBi during the execution of the process (S3a).

  When detected (YES in S3a), reading of data 25 of the data block DBi (S6) is skipped from the position of the offset OFk indicated by the deletion start index IDS, and the offset OFk indicated by the corresponding deletion end index IDE is set. That is, a search is performed to detect the deletion end position in the data 25 (loop processing of S3b and S3c).

  When the deletion end position is detected, the position is recognized as the next reading start position of the data 25, and the process proceeds to the reading operation after S4.

  Therefore, when a program for which a deletion point has been specified is reproduced, for the data 25 of each data block DBi, the data of the portion specified by the read deletion start index IDS and deletion end index IDE is skipped. Since the data is not reproduced, the data of the part designated by the user to be deleted is not reproduced in the subsequent reproduction operation.

  In the above procedure, at the time of reproduction, each time each data block DBi is reproduced, a process (S3a) for confirming whether or not the deletion start index IDS has been set for the data block DBi is performed. The procedure of 7 may be performed.

  In the procedure of FIG. 7, it is determined based on the valid / invalid data APj for each program whether or not the program to be reproduced is a program for which deletion points (deletion start index IDS and deletion end index IDE) have been set. (S2a) If the determination result is valid, the process after S3 shown in FIG. 6 is executed, and if it is invalid, the processes of S3 to S7 in FIG. 7 are executed selectively. You may do it.

  In this way, the deletion point detection process is performed for each data block DBi only when the program with the deletion point set is played back. Therefore, when all the programs are played back, the deletion point detection is performed for each data block DBi. As compared with the case where the process is executed, it is possible to suppress an increase in the load on the CPU 10 related to the program reproduction at the deletion point.

  In the first embodiment, the deletion point is set by repeating the one-touch operation of the delete button 141. Therefore, an error may occur in the operation content. For this reason, the following third and fourth embodiments are shown in order to avoid that data corresponding to a deletion point set with a mistake is deleted (can be overwritten). In the third embodiment, two example procedures for updating the deleted portion set in the first embodiment by subsequent user operations are shown, and in the fourth embodiment, two example procedures for editing are shown.

(Embodiment 3)
(First example)
The deletion point set by the deletion start index IDS and the deletion end index IDE set in the procedure of the first embodiment can be arbitrarily canceled according to the procedure of FIG.

  If the user desires to cancel the setting of the valid / invalid data APj and gives an instruction to that effect to the apparatus of FIG. 1 via the remote controller 14 according to the procedure of FIG. 8, the CPU 10 inputs the instruction. Accordingly, a screen as shown in FIG. 9 is displayed on the output unit 9 accordingly.

  For the screen of FIG. 9, the CPU 10 refers to the system block SB, reads the titles of the programs indicated by the index data IDj for each of the recorded programs, and displays them as a list via the OSD circuit 15 (S40). ). In this program title list, only the titles of programs whose corresponding valid / invalid data APj indicates “valid” are displayed in a list.

  The user designates a desired program title by operating the cursor key 143 with reference to the screen of FIG. 9 (the title indicated by the arrow AR in FIG. 9 is designated), and then presses the enter button 142. (YES in S41 and S42), the CPU 10 switches the display of “valid” corresponding to the program of the title to “invalid” and rewrites the valid / invalid data APj for the program in the system block SB to “invalid”. (S43).

  Thereafter, it is determined whether or not the program designation by the cursor key 143 is finished (S44). If the designation is finished, the series of processes is finished. If not, the process returns to S41 and the subsequent processes are repeated in the same manner.

  According to the procedure of FIG. 8, the valid / invalid data APj for each program can be arbitrarily rewritten from “valid” to “invalid” by the user's operation. When the rewritten program is reproduced according to the procedure of FIG. 7, it is determined that there is an invalidation instruction (YES in S2a), and the processes of S3 to S7 of FIG. 7 are executed.

(Second example)
The deletion point based on the deletion start index IDS and the deletion end index IDE set in the procedure of the first embodiment can be arbitrarily released according to the procedure of FIG. This procedure will be described below.

  First, when the CPU 10 inputs an instruction by an operation from the remote controller 14 according to a user's request, the title list of programs recorded in the HDD 5 is displayed on the output unit 9 via the OSD circuit 15 as shown in FIG.

  When the user selects a desired program title from the program title list by operating the remote controller 14, the CPU 10 displays the operation menu of FIG. 12 on the output unit 9 via the OSD circuit 15. Since the user selects “update deletion point” from the menu items in FIG. 12, when the CPU 10 inputs the selection instruction from the remote controller 14, the process of FIG. 10 is started. At the start of this process, data other than the data 25 in FIGS. 2A to 2D is read from the HDD 5 and temporarily placed in the RAM 12 and updated. After the processing is completed, the updated contents are read from the RAM 12 and overwritten (recorded) on the original contents of the HDD 5.

  First, the CPU 10 displays the screen of FIG. 13 on the output unit 9 via the OSD circuit 15 (S50). It is assumed that the program selected on the screen of FIG. 11 has a deletion point set by the procedure of the first embodiment. The CPU 10 searches the data block DBi of the selected program in the RAM 12 to obtain the data length, and determines the data position and length of the deletion indicated by the deletion point (deletion start index IDS and deletion end index IDE) in the calculated data length. Ask. Then, as shown in the screen of FIG. 13, a band-like shape relatively indicating the time series position and length (size) of the program data group of the data to be deleted in the line 20 indicating the program data length. Boxes 30 and 31 are displayed.

  In FIG. 13, a box 30 is instructed by the cursor CR, and a message box 41 for inquiring whether or not the data in the box 30 may be deleted is displayed. An area 40 for repeatedly displaying the box image indicated by the cursor CR is also provided on the same screen. The video in the area 40 is displayed as follows. That is, the CPU 10 reads out the data 25 corresponding to the box indicated by the cursor CR from the HDD 5 and outputs the data 25 from the decoder 7 to the analog conversion unit 8, so that it is synthesized with the drawing data output from the OSD circuit 15 and displayed as a moving image. .

  Returning to FIG. 10, the CPU 10 designates the first deletion portion (for example, the box 30) with the cursor CR (S51). The video corresponding to the box indicated by the cursor CR is repeatedly displayed in the area 40 (S52).

  The user monitors the video in the area 40, determines whether or not to execute the complete deletion process (OK or NG) for the currently instructed deletion part (box), and inputs the instruction via the remote controller 14. (S53). Here, the “complete deletion process” refers to a process of updating the corresponding usage information in the mapping table MPT from the used data UF to the all unused data AUF in units of block DBi for the data corresponding to the deleted portion. Note that the data block DBi that is partially unused data PUF is not updated.

  When NG is input (NO in S53), the process proceeds to S56 described later. However, when OK is input (YES in S53), the CPU 10 changes the box indicated by the cursor CR to the display of the line 20. (S54), complete deletion processing is performed on the data in the box (S55).

  Thereafter, the CPU 10 determines whether or not there is a next box (S56). If so, the process returns to S51 and the next deleted portion box is indicated by the cursor CR, and the subsequent processing is similarly repeated. Next, if there is no box, the process of FIG. 10 is terminated and, for example, the screen of FIG. 11 or 12 is displayed.

  By performing such an update procedure, the deletion part data specified in the first embodiment is completely deleted with the user's consent, so it is necessary for the deletion part specifying operation error. Can prevent accidental complete deletion of data. Further, since the usage information corresponding to the completely deleted data is updated to all unused data AUF, the area where the data is recorded in the HDD 5 can be used as a new data writing area.

(Embodiment 4)
Two examples of updating (editing) the deleted portion set in the first embodiment by subsequent user operations are shown below.

(First example)
The set deletion points (deletion start index IDS and deletion end index IDE) can be edited by a user operation according to the flowchart of FIG.

  First, in the editing mode of the deletion point, in FIG. 14, the CPU 10 displays a list of program titles with index data IDj whose valid / invalid data APj is “valid” from the system block SB on the output unit 9 as shown in FIG. To do. The user refers to the program title list display and operates the cursor key 143 to specify, for example, the program indicated by the arrow AR, and subsequently the deletion point start point (deletion start index IDS) and end point (deletion end index). IDE) is designated by designating button 91 or 92 on the screen of FIG. 15 (S60). When the CPU 10 subsequently detects that the user has pressed the enter button 142, it determines that an editing instruction has been input (S61). The CPU 10 reads the scene data corresponding to the designated point from the data 25 of the corresponding block DBi and displays it in the area 94 on the same screen in FIG. 15 (S62).

  When the user confirms the displayed scene and presses the cursor key in the right direction of the cursor key 143 for a long time, the point pointed in accordance with the long-pressed period is advanced in the arrow direction of the time axis in FIG. (YES in S63).

  During the long-pressed period, the CPU 10 displays the scene data recorded thereafter from the point designated in S60 of the corresponding block DBi while sequentially updating the data 25 in the read area 94 (S65). When the desired scene is displayed in the area 94, the user ends the long press of the cursor key (YES in S66), and then presses the enter button 142 (YES in S67). Thereby, the CPU 10 changes the point (deletion start index IDS or deletion end index IDE) instructed in S60 using the index time data ITk corresponding to the currently displayed scene (S68).

  Thereafter, the CPU 10 determines whether or not the screen end button 93 is input by operating the remote controller 14 (S69). If it is input, the series of processing ends. If not, the processing returns to S61.

  On the other hand, when the enter button 141 is not pressed even after the long press is finished (NO in S67), the process returns to S61.

  If it is determined in S63 that the cursor key is not pressed for a long time, it is determined whether or not the end button 93 is input (S64). If the end button is input, the series of processing is terminated, and if not, the processing returns to S61.

  In this example, the deletion start index IDS or the deletion end index IDE is updated so as to advance in the arrow direction of the time axis in FIG. 3, but may be updated so as to advance in the direction opposite to the arrow direction.

  Further, the deletion start index IDS is edited so as to be set beyond the deletion end index IDE, or the deletion end index IDE is edited so as to be set beyond the deletion start index IDS, so that the deletion is started. When an editing operation is performed such that the position of the point and the end point of deletion are reversed, the CPU 10 displays a message for advising an appropriate editing operation on the output unit 9 together with a message to that effect. May be.

(Second example)
The deletion point based on the deletion start index IDS and the deletion end index IDE set in the procedure of the first embodiment can be edited according to the procedure of FIG. 16 and completely deleted as desired. This procedure will be described below.

  First, the CPU 10 displays the screens of FIGS. 11 and 12 on the output unit 9 through the OSD circuit 15 in the same manner as described above. The user confirms the display screen, selects the title of the program for which deletion point editing is desired, and selects “edit deletion point” from the menu items in FIG. When the CPU 10 inputs the selection instruction from the remote controller 14, it starts the process of FIG. At the start of this process, data other than the data 25 in FIGS. 2A to 2D is read from the HDD 5 and temporarily placed in the RAM 12 to be updated. After the process is completed, the data is returned to the HDD 5 to return to the original contents. Is overwritten (recorded).

  First, the CPU 10 displays the screen of FIG. 17 on the output unit 9 via the OSD circuit 15 (S70). It is assumed that the program selected on the screen of FIG. 11 has a deletion point set by the procedure of the first embodiment. The screen of FIG. 17 displays the line 20 indicating the program data length, boxes 30 and 31, a cursor CR, an area 40, and a message box 41 on the line 20, as well as the screen of FIG. A pointer PI that moves according to the operation of the cursor key 143 or the skip button 144 on the box is newly displayed. When the pointer PI moves at the end of the box, the CPU 10 expands and contracts the box along the line 20 in accordance with the movement. Expansion and contraction of the box means updating the corresponding data recording area by increasing or decreasing the range (size).

  In the area 40, an image of the data 25 corresponding to the current position of the pointer PI on the box (or line 20) is displayed. The image data is read from the HDD 5 by the CPU 10 and output to the analog converter 8 via the decoder 7. As a result, the screen is synthesized with the drawing data output from the OSD circuit 15 and a screen as shown in FIG. 17 is displayed.

  The message box 41 moves with the movement of the pointer PI, is positioned near the pointer PI, and a message indicating that the pointer PI can move on the line 20 in either the left or right direction is displayed. .

  Returning to FIG. 16, the CPU 10 sets the cursor CR and the pointer PI (S71). For example, it is set to the point P 1 that is the head of the first box 30. Then, an image corresponding to the current position of the pointer P1 is displayed in the area 40 (S72).

  When the user monitors the image in the area 40 and determines that the position (recording area) of the deletion portion currently instructed by the pointer PI is appropriate, the user operates the decision button 142, so that the CPU 10 inputs the button operation instruction. (YES in S73), the process proceeds to editing of the deletion point (S74).

  In editing the deletion point, the CPU 10 specifies the index time data ITk of the data corresponding to the position of the pointer PI when the determination button 142 is operated, and if the position of the pointer PI is the start end of the box, the specified index The time data ITk is set as a new deletion start index IDS, and if it is the end of the box, it is set as a new deletion end index IDE. If the pointer PI has not moved, the editing process may be omitted.

  Thereafter, when the user operates the delete button 141 of the remote controller 14 and the CPU 10 inputs a delete instruction (YES in S75), the CPU 10 executes the above-described complete delete process for the data in the box where the pointer PI is currently positioned (S76). ). Then, the box display is changed to a line display (S77).

  After executing the complete deletion process and changing to the line display, or when the enter button 142 is not operated in S73 (NO in S73), or when no deletion input is made (NO in S75), the fine adjustment of the pointer PI is performed. It is determined whether or not it is made (S80).

  When the user finely adjusts the position of the current pointer PI, the cursor key 143 is operated (YES in S80), and the CPU 10 moves the pointer PI along the line 20 in accordance with the operation instruction of the cursor key 143, and the position. Is set (S71), and the subsequent processing is performed in the same manner as described above. The moving amount and moving direction for fine adjustment are determined according to the operation content of the cursor key 143.

  Since the user operates the skip button 144 when skipping the current position of the pointer PI (YES in S81), the CPU 10 skips the pointer PI along the line 20 in accordance with the operation instruction of the skip button 144. The position is set (S71), and the subsequent processing is performed in the same manner as described above. The amount of movement (moving speed) and moving direction per unit time in skip movement are determined according to the operation content of the skip button 144. Here, with reference to FIG. 17, the skip movement of the pointer PI refers to the pointer PI from the point P1 to P2, from P2 to P3, from P3 to P4, from P4 to P3, from P3 to P2, and from P2 to P1. This is the state where the robot is moved away.

  Thereafter, the processing is repeated until a user operation for ending editing of the deletion point is performed (YES in S82). When the editing process is completed, the CPU 10 displays the screen of FIG. 11 or 12 and waits for the next operation.

  Here, an image corresponding to the position of the pointer PI is displayed in the area 40, but this image may be a still image, and when the pointer PI is finely adjusted and moving, the speed of movement A moving image may be displayed at the same time.

  By performing such an editing procedure, the deletion part data specified in the first embodiment is completely deleted with the user's consent, so it is necessary for a mistake in specifying the deletion part. Can prevent accidental complete deletion of data. Further, the data to be completely deleted can be arbitrarily changed. Since the usage information corresponding to the data completely deleted by this editing procedure is updated to all unused data AUF, the area in the HDD 5 where the data was recorded can be used as a new data writing area.

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