Description

  The present invention relates to a hard disk recording / reproducing apparatus that receives analog broadcasts and digital broadcasts, records them on a built-in hard disk, and reproduces and edits broadcast programs recorded by subsequent user operations, and editing of recorded programs Regarding the method.

  There is a recording / playback apparatus for television broadcasting using a hard disk as a recording medium. The hard disk has a large capacity, can record TV programs for a long time, and has a much shorter access time such as cueing than an analog video tape recorder (hereinafter referred to as VTR). In recent years, it has been spreading rapidly.

One of the advantages of this hard disk recording / reproducing apparatus over the VTR is the editing function during recording.
That is, for example, when recording a two-hour movie on a VTR, if a user wants to record a movie that does not need to be recorded, such as a trailer before and after the movie, the user can watch the video in real time while watching the video in real time. It was cumbersome because we had to stop and re-record. In addition, since the operation is performed in real time, it is possible that the video to be recorded cannot be recorded when the timing of the pause or the like is wrong, which is a difficult operation for the user.

  On the other hand, recording editing in the hard disk recording / reproducing apparatus is normally performed as follows. An example of recording and editing the above two-hour movie will be described. Once the entire hard disk has been recorded for 2 hours, the user switches the device to edit mode. In the edit mode, the operation screen 1 shown in FIG. 5 is displayed on the monitor screen by the OSD (On Screen Display) function. Therefore, the user operates the remote controller at hand to perform the editing operation while viewing the operation screen 1.

  That is, since the horizontal line 2 that appears on the operation screen 1 shows a time chart of a recorded two-hour program, the user has displayed unnecessary part positions such as trailers before and after that on a part of the screen. While looking at the small screen 3 (thumbnail screen), search is performed by performing operations such as fast-forward or frame-by-frame. And after confirming an unnecessary part, remote control operation is performed and the said unnecessary part is deleted.

  As described above, in the hard disk recording / reproducing apparatus, unnecessary portions can be confirmed while looking at the small screen in the edit mode. Therefore, the accuracy of the edit position is easily ensured as compared with the VTR, and it is unnecessary in the edit mode at once. Since the part can be specified and deleted, the operation is easy to understand.

  However, the hard disk recording / reproducing apparatus has the following inconvenience. That is, in the editing mode, the user must search for an unnecessary portion of a video (a trailer, a CM, etc.) appearing on the small screen 3 by repeating fast forward and frame advance operations while looking at the small screen 3. Programs that the user intends to keep editing are usually viewed in real time at the time of broadcast or once played and viewed, so the approximate position of unnecessary parts can be guessed even in the edit mode screen. However, in most cases, an accurate position cannot be found unless operations such as fast forward and frame advance are repeated as described above.

Note that in video cameras that record video on a hard magnetic disk, key operations that allow easy setting of the erasure-prohibited section to prevent accidental erasure of important video files recorded on the disk. Japanese Patent Application Laid-Open No. 2003-228561 discloses a technique that can be performed in this manner, but this is not a technique related to editing recorded video information (program) afterwards.
JP-A-9-168129

  The present invention eliminates the inconvenience at the time of editing in a hard disk recording / reproducing apparatus, and in particular, it is an object of the present invention to facilitate searching for points to be edited in an editing mode.

The control unit records the received program on the hard disk according to the setting from the operation unit. In a hard disk recording / reproducing apparatus that executes by selectively switching between a recording mode to be performed, a reproduction mode for outputting the program recorded on the hard disk to the video output means, and an editing mode for editing the recorded program, In the operation unit, when the control unit executes the recording mode or the playback mode, by the user's operation, An edit button for designating an edit point indicating the position of the video output to the video output means at the time of creation and storing it in the control means is provided, and when the control means executes the edit mode, The playback screen in the edit mode is provided with a move button for moving to a video at a position specified by the edit point by an operation.

  The invention of claim 3 is a hard disk as a recording medium, a TV broadcast reception tuner, a recording of a TV program received by the reception tuner to the hard disk, and a reproduction output of the recorded program to a video output means such as a TV monitor. A control unit for controlling the control unit, and an operation unit connected to the control unit for setting the control content of the control unit by a user operation. The control unit records the received program on the hard disk according to the setting from the operation unit. Recording in a hard disk recording / reproducing apparatus that executes by selectively switching between a recording mode to be performed, a reproduction mode for outputting the program recorded on the hard disk to the video output means, and an editing mode for editing the recorded program In the program editing method, when the recording mode or playback mode is executed, the user can edit the editing button on the operation unit. The edit point indicating the position of the video being played back with respect to the program is specified, and when the edit mode is executed, the user operates the move button on the operation unit to display the edit mode playback screen. It moves to the image | video of the position designated by the said edit point, and edit processes, such as deletion of the recording part shown by the edit point, and preservation | save, are performed after that.

  The invention of claim 4 for solving the above-mentioned problem is the invention of claim 3, wherein the editing process is separated from the editing mode, and is a time zone that is not frequently used by a user such as midnight, and It is characterized in that it is automatically executed in a time zone in which no scheduled recording is set.

  As described above, according to the first aspect of the present invention, the user can watch the video output to the video output means such as the TV monitor in the recording mode or the playback mode, while viewing the video that is not necessary (for example, a movie trailer, CM When the edit button is operated and the edit point is specified and the edit mode is switched to the edit mode later, the edit mode playback screen can be edited by simply operating the move button on the operation unit. Since the screen moves to the point screen, editing operations such as deletion can be performed using the point as an editing point, and there is no trouble in searching for the editing point.

  In addition, when a part that should be clearly deleted during viewing, such as a CM, appears, the edit button is operated at the start of the CM, and then the delete button of the operation unit is pressed at the end of the CM. If you operate, the part from the point specified with the delete button to the point specified with the previous edit button is automatically deleted, so you can save the trouble of deleting the unnecessary part again after switching to edit mode .

  According to the second and third aspects of the present invention, the user can watch an unnecessary part (for example, a movie trailer) while watching the video output to the video output means such as a TV monitor in the recording mode or the playback mode. When the edit button is operated and the edit point is specified, the edit mode playback screen is specified first by simply operating the move button on the operation unit when the edit mode is subsequently switched. Since the editing point is moved to the editing point screen, editing operations such as deletion can be performed using the editing point as the editing point.

  Further, according to the invention of claim 4, the deletion of unnecessary portions set in the edit mode or the data rearrangement (defragmentation) operation associated therewith is separated from the edit mode, and the frequency of use by the user at midnight or the like Since it is automatically executed in a time zone in which no scheduled recording is set, the waiting time of the user in the edit mode is eliminated.

  A hard disk recording / reproducing apparatus according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, a hard disk recording / reproducing apparatus 10 of this embodiment includes a television broadcast reception tuner 11, an NTSC decoder 12 for converting a broadcast signal received by the reception tuner 11 into digital data and a bit stream, and an ATSC front. It has an end 13 and a hard disk 14 as a large-capacity recording medium.

  A computer system 15 (hereinafter referred to as a system) is provided as a control means, and the system 15 controls the output of the digital data and the bit stream, or reads the recorded data from the hard disk 14, and the data. Is controlling the output. The system 15 is connected to a remote control light receiving unit 16, and the remote control light receiving unit 16 is wirelessly connected to an external remote control 17 by infrared rays, and various settings are given to the system 15 by a user operating the remote control 17. . Therefore, in this embodiment, the remote controller 17 and the remote controller light receiving unit 16 constitute an operation unit. The remote control 17 is provided with an edit button 18, which will be described in detail later, a move button 19 and a delete button 20.

  Reference numeral 21 denotes an MPEG decoder that converts a bit stream into video, and 22 denotes an OSD that performs graphic processing on the converted video. A video signal from the OSD 22 is output to an external television monitor 23 as video output means. Reference numeral 24 denotes an antenna for receiving broadcast radio waves. In addition, what is called a video, a video signal, and a video output in this specification includes a voice, a voice signal, and a voice output.

  As shown in FIG. 2, the remote controller 17 is provided with a mode switching button 25 for switching the operation mode. By operating the mode switching button 25, the setting of the system 15 is changed, and the recording / reproducing apparatus has the setting. The mode is switched between recording mode, playback mode and editing mode. That is, when the recording mode is set, the system 15 sends the bit stream from the NTSC decoder 12 to the MPEG decoder 21 so that it can be viewed on the television monitor 23 and simultaneously sent to the hard disk 14. 14 to record the program.

  When the playback mode is set, the system 15 reads the program designated by the user from the hard disk 14, outputs the program to the MPEG decoder 21, and outputs the video to the television monitor 23. When the apparatus operates as a normal television tuner, the system 15 passes the bit stream from the NTSC decoder 12 and sends it to the MPEG decoder 21.

  Next, the edit mode will be described. When the editing mode is set, the system 15 reads the program data designated by the user from the hard disk 14 and displays the operation screen 26 shown in FIG. 3 on the television monitor 23 via the OSD 22. That is, a horizontally long line 27 representing the entire read program (recording time time chart) is displayed at the bottom of the screen, and a processing type such as a small screen 28, “delete” 29, and “save” 30 is displayed above it. Is displayed. The operation screen in the editing mode can be variously modified such as design and layout.

  The video displayed on the small screen 28 is a video at a certain time point selected by the user in the recorded program. This video is recorded in a predetermined range corresponding to the first screen (for example, the CM portion) by the user. If judged to be unnecessary, the user selects the “delete” display 29 on the screen by operating the cross key 31 or the like of the remote controller 17 and then presses the enter button 32, and the recording of that portion is recorded on the hard disk 14. Has been removed from.

  In the present invention, an appropriate image (an image designated by the user as an editing point in advance) can be easily displayed by simply pressing the move button 19 on the remote controller 17 for the image appearing on the small screen 28 (an image serving as an editing point). Is done.

  In other words, the remote controller 17 of the present invention is provided with an edit button 18, and in the recording mode or the playback mode, the user can watch a certain program on the TV monitor 23 and delete a video portion (for example, CM, movie trailer) to be deleted. If the edit button 18 is pressed, the video position is stored in the system 15 in association with the program. In FIG. 1, 15a is RAM which memorize | stores the image position in the system 15. FIG. The edit button 18 is pushed over a plurality of places where the user later wants to edit or delete, and therefore usually two or more edit points are stored in one program. The stored video position (edit point) is displayed as follows in the edit mode.

  That is, as shown in FIG. 3, the edit point designated by the user by the above operation is displayed as a mark 33 on the horizontally long line 27 in the edit mode. The mark 33 is displayed on the television monitor 23 via the OSD 22 according to the video position information read from the RAM 15a in the system 15.

  Next, when the user presses the movement button 19 of the remote controller 17, the video on the small screen 28 jumps to the video at the position where the mark 33 is attached (position on the time chart), and the same operation is repeated. As a result, the video on the small screen 28 jumps to the video at the next mark 33 position. The video displayed on the small screen 28 in this way is the video that the user himself / herself specified by operating the edit button 18 when viewing the program, so it should be the correct editing point, but the user dares to slightly shift the point back and forth. If it is desired to do so, it can be changed by operating the fast-forward or fast-rewind key on the remote controller 17. Note that the recorded parts deleted by the above operation are the parts R1 and R2 (FIG. 3) between the two editing points (marks 33).

  Next, an operation using the delete button 20 of the remote controller 17 for determining deletion at the stage of viewing a video in the recording mode or the playback mode will be described. That is, for a part that the user can clearly decide to delete at the time of the first viewing, such as CM, if the following operation is performed, the deletion operation is switched to the edit mode and the above-described steps are performed. Deletion is executed without any operation.

  That is, when the user is viewing the video in the recording mode or the playback mode, if the video part to be deleted (CM part) is reached, the edit button 18 is first pressed, and then the part to be deleted is completed. Press the delete button 20 on the remote controller 17. By this operation, the system 15 stores the video position where the edit button 18 and the delete button 20 are pressed, and decides to delete the video part between them. Therefore, the user can omit the deletion operation for the above portion after switching to the edit mode again.

  If there is no edit point in front of the position where the delete button 20 is operated (in time chart, in time), the program is deleted from the beginning. That is, if there is a video part sandwiched between the position specified by the delete button 20 and the position specified by the edit button 18 in front of it, the video part is deleted and edited before the position specified by the delete button 20. If the point is not specified, the position from the beginning of the program to the position specified by the delete button 20 is deleted.

  Next, an embodiment will be described in which editing processing such as deletion and storage determined in the editing mode is automatically executed in a time zone where the frequency of use by the user is low, such as midnight.

  That is, the execution of the editing process determined as described above is normally performed after the determination of the editing process contents in the editing mode. However, there are many deleted parts or the free space of the hard disk 14 is not sufficient. If the relocation (defragmentation) of the recording area in the hard disk 14 is automatically performed in a small number of cases, it takes a considerable amount of time, resulting in useless waiting time for the user.

  In the second embodiment, the editing process is executed as follows separately from the editing mode by the user. That is, as shown in the flowchart in FIG. 4, it is detected that a predetermined midnight time zone (for example, 3 am) is reached by a timer (not shown) built in the recording / reproducing apparatus 10, and the editing process is automatically performed. First, it is determined whether or not the reserved recording has been performed (step 1). If there is a reservation, the editing process is terminated.

  If there is no reservation, it is determined whether there is a program to be deleted (step 2), and if there is, a predetermined deletion process is executed (step 3). If there is no program to be deleted in step 2, it is determined whether or not defragmentation is necessary (step 4). If not necessary, the process is terminated, and if necessary, defragmentation is executed (step 5).

  Further, after the deletion process is executed or the defragmentation process is executed, it is judged whether or not the user has performed any input operation with the remote controller 17 or the like (step 6). Return to 1. A program for executing the flowchart is stored in the system.

  In step 2 above, it is determined whether there is a program to be deleted. This is because a large number of programs are recorded in the hard disk 14, and some of the many programs are recorded as programs. This is an example when the user designates deletion. Therefore, in the example of the first embodiment, it is determined whether there is a portion (deleted portions R1, R2) sandwiched between editing points.
