Description

  The present invention relates to a recording / playback apparatus and a recording / playback method having a plurality of program playback modes.

  In recent years, in the function of a recording / playback apparatus, an efficient program playback method is regarded as important. The reason for this is the increase in the number of recorded programs as the capacity of recording media such as HDDs (hard disk drives) increases. Since the capacity of the recording medium becomes an important element of the product, the capacity of the recording medium is rapidly increasing year by year. As a result, the number of programs recorded in the recording / playback apparatus has increased, making it difficult to search for a program desired by the user from a plurality of programs. Therefore, in order to improve the convenience for the user, an efficient reproduction method of the recorded program is important.

  For this reason, a technique has been proposed in which a recorded program is automatically reproduced without a user explicitly specifying a recorded program (see, for example, Patent Document 1).

  This classifies recorded programs according to genre, arranges the recorded programs in time series for each genre, and broadcasts from each virtual genre that a recorded program is reproduced for each genre. Assuming that a virtual channel is allocated, and a program (broadcast program) broadcast from an actual broadcasting station is a real channel program, the time passes on the same time axis as the real channel and the virtual channel. When any one of the real channel and the virtual channel is designated, the program to be displayed at the time of the designated channel is displayed. If any real channel is specified, the program broadcast at this specified time on this real channel is received and displayed, and if any virtual channel is specified, this specified virtual channel is displayed. The recorded program to be displayed at the designated time is reproduced and displayed.

In the case of a recorded program on a virtual channel, fast forward, rewind, and playback can be paused. However, the time flow between the real channel and the virtual channel is not affected by these.
JP 2001-333358 A

  In the technique described in Patent Document 1, when a user wants to play back a recorded program, the user only has to select a virtual channel from the channels, and the recorded program of the specified virtual channel can be selected without explicitly specifying the program. It can be played and viewed.

  However, the recorded program reproduced in this way is a recorded program to be reproduced at the time designated by the virtual channel, and is not necessarily the recorded program desired by the user. That is, when a user tries to perform playback without explicitly specifying a recorded program, the recorded program desired by the user is not always played back.

  On the other hand, as an example of a recording / playback apparatus, even if a user does not explicitly specify a recorded program to be played back (that is, without specifying a directly recorded program), playback can be paused by operating a playback key on the remote controller. 2. Description of the Related Art A recording / playback apparatus having a function of performing so-called resume playback, in which playback of a recorded program in a state is started from a position at which it is paused, is known. In such a recording / playback apparatus, when a recorded program in the playback pause state is to be played back for viewing, it can be played back continuously from the paused position only by operating the playback key on the remote control. In particular, it is possible to reproduce the recorded program to be reproduced without directly specifying the recorded program. The above-mentioned patent document 1 also describes that a resume function for the recording / playback apparatus is provided.

  Another example of the recording / playback apparatus is a so-called chasing playback function in which, when an input program such as a broadcast program is being recorded, if the user operates the playback key on the remote controller, the recorded program starts to be played back from the beginning. There is also known a recording / playback apparatus including In such a recording / playback apparatus, when the user wants to play back the program being recorded at that time, it can be played back simply by operating the playback key on the remote controller.

  By the way, in a recording / playback apparatus having a resume playback function, if it is desired to continue playback of a recorded program that has been played halfway and paused, the recorded program is not specified directly. By operating the playback key on the remote control, this program can be easily played back, but if you wish to play back the program being recorded, you can receive this broadcast program and display it on the display. This requires another operation such as making the operation, which takes time. The same applies to a recording / playback apparatus having a chasing playback function. When playback of a program being recorded is desired, it can be easily performed by operating the playback key of the remote control without directly specifying the program. If the program being recorded can be played from the beginning, it can be played back halfway, but if you want to continue playing the recorded program that has been paused, play the remote In this operation, the re-juice reproduction of the recorded program is not performed, and another operation for releasing the pause of the recorded program and starting the reproduction is necessary, and there is a problem that the operation becomes complicated.

  As described above, the conventional recording / playback apparatus is configured to be able to play back the desired recorded program without explicitly instructing the desired recorded program, but can play back the desired recorded program. Therefore, there is a problem that an operation suitable for selecting the program reproduction mode is required for each program reproduction mode, and an operation means for that is required for each program reproduction mode.

  An object of the present invention is to solve such a problem, simplify operation means and operation methods for selecting a plurality of reproduction program selection modes, and even if a user does not explicitly instruct a reproduction program, the program desired by the user It is an object to provide a recording / reproducing apparatus and a recording / reproducing method that can reproduce the above.

  In order to achieve the above object, a recording / playback apparatus according to the present invention provides a recorded program that can be played back in the playback program selection mode for each of a plurality of playback program selection modes that can be played back without explicit designation of the program by the user. And a user interface for selecting one of the playback program selection modes. By selecting the playback program selection mode on the user interface, the program is played back without explicit designation of the program by the user. This is characterized in that a recorded program can be designated.

  The recording / playback apparatus according to the present invention is characterized in that the user interface can select a playback program selection mode in which playback of a recorded program can be started.

  The recording / playback apparatus according to the present invention sets a recorded program that can be played back in the playback program selection mode for each of a plurality of playback program selection modes that can be played back without explicit designation of the program by the user. Means, second means for simultaneously reproducing recorded programs in all reproduction program selection modes, third means for simultaneously displaying all the recorded programs reproduced by the second means on the display screen, And a fourth means for selecting any one of the recorded programs displayed by the means, and a means for displaying only the recorded program selected by the fourth means on the display screen. is there.

  In the recording / playback apparatus according to the present invention, the playback program selection mode includes at least a resume playback mode in which playback of a recorded program in a playback pause state is started from the position when playback is paused, and a program being recorded. And a chasing playback mode in which playback is started from the beginning.

  In order to achieve the above object, the recording / playback method according to the present invention provides a recorded program that can be played back in the playback program selection mode for each of a plurality of playback program selection modes that can be played back without explicit designation of the program by the user. Is set so that one of the reproduction program selection modes can be selected, and the recorded program to be reproduced is determined from the selected reproduction program selection mode and the recording state.

  Further, the recording / playback method according to the present invention includes a resume playback mode in which the playback program selection mode starts playback from the position at which playback of the recorded program is paused at least, and the program being recorded. And a chasing playback mode in which playback is started from the beginning.

Here, the recording medium 9 is incorporated in the recording / playback apparatus 1, but is provided outside the recording / playback apparatus 1 together with the recording processing section 7 and the playback processing section 8. It may be an external device provided.

  Next, the operation of this embodiment will be described.

  When video / audio signals input from the video / audio input terminal 12 are recorded on the recording medium 9, the remote controller is operated to request recording. The recording request operation signal is input from the operation signal input terminal 13 to the recording / playback apparatus 1 and received by the user instruction receiving unit 4, and the control unit 3 is notified of the recording request. In response to this recording request notification, the control unit 3 controls each unit of the recording / playback processing device 2 to perform a recording operation. Thereby, the recording process is started.

  By starting the recording process, an analog or digital video / audio signal of a program input from the video / audio input terminal 12 is supplied to the video / audio switching unit 5. The video / audio switching unit 5 sends the supplied video / audio signal to the recording processing unit 7 under the control of the control unit 3. In the recording processing unit 7, the supplied video / audio is management information (for example, program management program ID, video / audio information amount, etc.) and program information (for example, program start time, end time, program time, Channel number, title name, etc.) are added and encoded into a recording stream. The encoded program recording stream is recorded on the recording medium 9.

  In this way, the video / audio signal of the input program is recorded on the recording medium 7 in accordance with the user instruction.

  The broadcast program of the channel desired by the user or the playback video / audio from the external recording / playback apparatus is connected to the video / audio output terminal 14 while being recorded on the recording medium 9 or not being recorded on the recording medium 9. It is also possible to display on a display unit (not shown) (this is hereinafter referred to as a display mode). In this case, an operation for requesting this display mode with a remote control (for example, in the case of a broadcast program, a channel designation operation, external recording / playback) In the case of a device, the control unit 3 starts the operation of the display mode of the recording / playback processing device 2 by performing a key operation for designating the device. Thereby, in the recording / playback processing apparatus 2, the video / audio signal input from the video / audio input terminal 12 is supplied to the output video / audio switching unit 6 by the video / audio switching unit 5. The output video / audio switching unit 6 selects a video / audio signal from the video / audio switching unit 5 under the control of the control unit 3, and a display unit (not shown) from the video / audio output terminal 14 via the video synthesis unit 10. To supply. Thereby, the video / audio of the broadcast program of the channel desired by the user or the reproduced video / audio from the external recording / reproducing apparatus is displayed on the display unit so that the user can view it.

  When reproducing a program (recorded program) recorded on the recording medium 9, the remote controller is operated to request reproduction. The reproduction request operation signal is input from the input terminal 13, received by the user instruction receiving unit 4, and the reproduction request is supplied to the control unit 3. The control unit 3 controls playback of each unit of the recording / playback processing unit 2 in response to the playback request.

  Here, when the user designates a desired recorded program among the recorded programs recorded on the recording medium 9 by a program ID added by the recording processing unit 7 by remote control operation, the recorded program of this program ID is recorded. The video / audio signal that is reproduced from the medium 9 and is encoded by the reproduction processing unit 8 is decoded and supplied to the output video / audio switching unit 6. At this time, the output video / audio switching unit 6 selects the video / audio signal from the reproduction processing unit 8 under the control of the control unit 3 and is illustrated from the video / audio output terminal 14 via the video synthesis unit 10. Not supplied to the display. Thereby, the recorded program designated by the user can be viewed on the display unit.

  In the first embodiment, the recorded program that is displayed and viewed on the display unit (not shown) can be paused in the middle. This is executed under the control of the control unit 3 in response to the pause operation of the remote controller, and the program ID and pause position of this recorded program (for example, when playback is paused from the beginning of this recorded program) Necessary information (hereinafter referred to as reproduction pause information) is stored in the control unit 3. The reproduction pause information is stored in the control unit as it is even when the recording / reproducing apparatus 1 is powered off. Using such playback pause information, it is possible to perform resume playback in which a recorded program in the playback pause state is continuously played back from the playback pause position.

  In the first embodiment, it is also possible to perform chasing playback in which a program being recorded on the recording medium 9 is played back from the beginning.

  In order to perform such resume playback or chasing playback, a playback key is provided on the remote control. When the user operates this playback key, the operation signal is input from the operation signal input 13, received by the user instruction receiving unit 4, and a playback request is notified to the control unit 3. In response to the reproduction request, the control unit 3 controls the OSD creation unit 11 to create a menu OSD screen. The OSD screen is supplied from the video / audio output terminal 14 to the display unit (not shown) via the video synthesis unit 10. Thereby, the OSD screen of the menu is displayed on the display unit.

  On the OSD screen of this menu, first, a plurality of main menus are displayed. When a desired main menu is selected by operating the remote control, for example, the up / down key and the enter key, a submenu for this main menu is displayed. When a desired one is selected, a menu that expands below the selected submenu is displayed.

  FIG. 2 is a diagram showing a specific example of an OSD screen of a selection menu of resume playback and chasing playback obtained by such an operation. 20 is a display screen of the display unit, 21 is a main menu, 22 is a submenu, , 24 is a selection menu, and 25 is a cursor.

  In the figure, here, the mode in which the user desires to reproduce the program, that is, the reproduction program selection mode, without specifying the program explicitly (directly), that is, the reproduction program selection mode, is the above-mentioned “resume reproduction” and “chase”. There are two modes of “playback”.

  The main menu “playback setting menu” 21 displayed on the display screen 20 is selected to execute resume playback or chasing playback from the list of the main menu, and the submenu “playback program selection mode” 22 The main menu “playback setting menu” 21 is selected to execute resume playback or chasing playback from a list of a plurality of submenus displayed by selection of the submenu “playback program selection”. By selecting “mode” 22, as shown in the figure, a “resume playback” icon 23 and a “chase playback” icon 24 in a sub-menu of the submenu “playback program selection mode” 22 are displayed. A cursor 25 indicated by shading is superimposed on either of the “resume playback” icon 23 and the “chasing playback” icon 24, and the icon on which the icon 25 overlaps is selected. The icon 25 is moved up and down by operating the up and down keys of the remote controller, whereby the “resume playback” icon 23 and the “chase playback” icon 24 can be appropriately selected.

  The main menu, submenu, icon, and cursor screens described above are created as OSD screens by the OSD creation unit 11 (FIG. 1), and the control unit 3 creates the OSD according to the operation of the up and down keys and the enter key of the remote control. By controlling the unit 11, the display content of the OSD screen displayed on the display screen 20 changes.

  The icon 23 is a shaded icon here, but may be a colored icon, a frame-like icon, or an icon of another form.

  As shown in FIG. 2, when the cursor 25 is on the “resume playback” icon 23 and this icon 23 is selected, when the determination key of the remote controller is operated, the operation signal is input to the operation signal. Input from the terminal 13, the user instruction receiving unit 4 receives it and sends a resume reproduction request notification to the control unit 3. When there is a recorded program in the playback pause mode in the recording / playback apparatus 1, the control section 3 controls each section of the recording / playback processing section 2 to start resume playback.

  At this time, if there is no recorded program in the playback pause mode, the control unit 3 controls the OSD creation unit 11 to create a message indicating that there is no such recorded program, and displays the screen of this message on the display unit. An OSD is displayed on the display screen 20. Alternatively, when there is no recorded program in the playback pause mode, the “resume playback” icon 23 may not be displayed on the OSD screen shown in FIG.

  In the state shown in FIG. 2, when the lower key of the remote control is operated to bring the cursor 25 to the “chase playback” icon 24 so that the icon 23 is selected and the determination key of the remote control is operated, the operation signal is changed. Input from the signal input terminal 13, the user instruction receiving unit 4 receives it and sends a chasing playback request notification to the control unit 3. When the recording / playback apparatus 1 is in a recording mode for recording a program, the control unit 3 controls each unit of the recording / playback processing unit 2 to record the program being recorded on the recording medium 9 (FIG. 1). Start chasing playback that plays back (program) from the beginning.

  At this time, if the program is not recorded on the recording medium 9 (that is, there is no program being recorded), the control unit 3 controls the OSD creation unit 11 to indicate that there is no program being recorded. A message is created, and the message screen is OSD-displayed on the display screen 20 of the display unit. Alternatively, when there is no program being recorded, the “chase playback” icon 24 may not be displayed on the OSD screen shown in FIG.

  In FIG. 1, in the case of resume reproduction, a resume reproduction start instruction is sent from the control unit 3 to the reproduction processing unit 8. This resume playback start instruction is added with playback pause information such as the program ID and pause position of the recorded program in the playback pause mode to be resumed. Upon receiving the resume playback instruction, the playback processing unit 8 plays back the recorded program recorded in the recording medium 9 and in the playback pause state based on the playback pause information by the pause command in the previous playback. Play from the position where was stopped. Thus, the encoded stream of the video / audio signal of the recorded program to be resumed from the recording medium 9 is decoded by the reproduction processing unit 8 and supplied to the output video / audio switching unit 6. At this time, the output video / audio switching unit 6 selects the video / audio signal from the reproduction processing unit 8 under the control of the control unit 3 and is illustrated from the video / audio output terminal 14 via the video synthesis unit 10. Not supplied to the display. As a result, the resumed recorded program can be viewed on the display unit.

  In the case of chasing playback, a chasing playback start instruction is sent from the control unit 3 to the playback processing unit 8. In this case, when the chasing playback request from the user instruction receiving unit 4 is notified, the control unit 3 obtains the program ID assigned to the currently recorded program from the recording processing unit 7, and tracks this. It is sent to the reproduction processing unit 8 together with a reproduction start instruction. Upon receiving this chasing playback start instruction, the playback processing unit 8 plays back the recorded program (ie, the currently recorded program) to which the program ID added thereto is added from the beginning. Thus, the encoded stream of the video / audio signal of the recorded program that is chased and reproduced from the recording medium 9 is decoded by the reproduction processing unit 8 and supplied to the output video / audio switching unit 6. At this time, the output video / audio switching unit 6 selects the video / audio signal from the reproduction processing unit 8 under the control of the control unit 3 and is illustrated from the video / audio output terminal 14 via the video synthesis unit 10. Not supplied to the display. As a result, the recorded program (that is, the program currently being recorded) reproduced in a chasing manner can be viewed on the display unit.

  FIG. 3 is a flowchart showing the processing algorithm of the first embodiment. Here, it is assumed that there is a recorded program in the playback pause mode.

  In the figure, when the user operates a reproduction key on the remote controller, the OSD screen shown in FIG. 2 is displayed on the display screen of the display unit as described above. When the user selects one of the icons 23 and 24 on the OSD screen, the user setting value (reproduction program selection mode) is set to either resume reproduction or chasing reproduction, and the reproduction set by the user. When the program selection mode (user setting value) is “resume playback” (“yes” in S (step) 31), the control unit 3 instructs the playback processing unit 8 to start resume playback (S32). Thereby, the reproduction | regeneration processing part 8 starts resume reproduction | regeneration as mentioned above. When the user setting value is “chase playback” (“no” in S31), the control unit 3 determines whether or not the current recording state is set, and when in the recording state (“yes” in S33). The control unit 3 instructs the reproduction processing unit 8 to start chasing reproduction (S34). Thereby, the reproduction | regeneration processing part 8 starts chasing reproduction | regeneration as mentioned above. If it is not currently in the recording state (“no” in S33), since there is no program to be chased and reproduced, the control unit 3 instructs the reproduction processing unit 8 to start resume reproduction (S35).

  If there is no recorded program in the playback pause mode or a program that is being recorded, even if the playback key on the remote control is operated, S32, S34, and S35 are not executed, and the control of the control unit 3 is terminated. As such, a message is displayed. Alternatively, as described above, the “resume playback” icon 23 and the “chase playback” icon 24 in FIG. 2 may not be displayed under the control of the control unit 3.

  In this way, in the first embodiment, the operation device such as the remote controller and the display unit constitute a user interface, and when the user wants to view the recorded program in the playback pause state, this recording is performed. Without specifying the program directly, it can be played back and viewed from the position where playback was paused by a simple operation on the operating device, and the recorded program can also be viewed as a recorded program. When viewing is desired, the recorded program can be reproduced and viewed from the beginning by a simple operation with the operation device without directly specifying the program being recorded.

  Even when resume playback or chasing playback is being performed, the “resume playback” icon 23 and the “chasing playback” icon 24 are displayed on the display screen 20, and switching between resume playback and chasing playback is also performed during such playback. You can also do it.

  FIG. 4 is a diagram showing a specific example of an OSD screen of a selection menu of resume playback and chasing playback in the second embodiment of the recording / playback apparatus and recording / playback method according to the present invention. On the screen, 41 is a “resume playback” icon, and 42 is a “chase playback” icon. The recording / playback apparatus according to the second embodiment also has the configuration shown in FIG. 1. Here, the display screen of the display unit connected to the video / audio output terminal 14 is indicated by reference numeral “40”. Yes.

  In FIG. 1, when the user operates the playback key of the remote controller, the operation signal is input from the operation signal input terminal 13, and the user instruction receiving unit 4 receives this and notifies the control unit 3 of an instruction to start playback. Upon receiving this notification, the control unit 3 controls the OSD creation unit 11 to create an OSD screen for starting resume playback or chasing playback. The generated OSD screen signal starts the video composition unit 10 and is supplied from the video / audio output terminal 14 to a display unit (not shown).

  As a result, the OSD screen is displayed on the display screen 40 of the display unit as shown in FIG. That is, the “resume playback” icon 41 and the “chasing playback” icon 42 corresponding to the “resume playback” icon 23 and the “chasing playback” icon 24 in FIG. 2 are directly displayed.

  Here, on this OSD screen, when the cursor is not displayed and the upper key of the remote control is operated in the display state shown in FIG. 4, the “resume playback” icon 41 displayed on the upper side is selected, and the lower key is operated. Then, the “chasing playback” icon 42 is selected.

  The processing algorithm associated with the up / down key operation on the OSD screen shown in FIG. 4 in the second embodiment is also the same as the flowchart shown in FIG.

  That is, when the “resume playback” icon 41 is selected by operating the upper key of the remote controller in the display state shown in FIG. 4 (“yes” in S31), the control unit 3 instructs the playback processing unit 8 to start resume playback. (S32). Thereby, the reproduction | regeneration processing part 8 starts resume reproduction | regeneration as mentioned above. When the “chase playback” icon 42 is selected by operating the lower key of the remote control (“no” in S31), the control unit 3 determines whether or not the current recording state is set. The control unit 3 instructs the reproduction processing unit 8 to start chasing reproduction (S34). Thereby, the reproduction | regeneration processing part 8 starts chasing reproduction | regeneration as mentioned above. If it is not currently in the recording state (“no” in S33), since there is no program to be chased and reproduced, the control unit 3 instructs the reproduction processing unit 8 to start resume reproduction (S35).

  Thus, also in the second embodiment, the operation device such as the remote controller and the display unit constitute a user interface, and when the user wants to view the recorded program in the playback pause state, the recording is performed. Without specifying the program directly, it is possible to continue playback and viewing from the position where playback was paused by a simpler operation of the operating device. When viewing is desired, the recorded program can be reproduced and viewed from the beginning by a simpler operation of the operation device without directly specifying the program being recorded.

  In the second embodiment, similarly to the first embodiment, the cursor is used, the cursor is moved by operating the operation device, and either of the icons 41 and 42 is designated, and the enter key is operated. By doing so, it is possible to execute resume reproduction or chasing reproduction corresponding to the instructed icon.

  Also in the second embodiment, the “resume playback” icon 41 and the “chasing playback” icon 42 are displayed on the display screen 40 even when resume playback or chasing playback is performed, and during such playback. It is also possible to switch between resume playback and chasing playback.

  If there is no recorded program in the playback pause mode or a recorded program, even if the playback key on the remote control is operated, S32, S34, and S35 in FIG. 3 are not executed, and the control of the control unit 3 ends. Then, a message is displayed as described above. Alternatively, as described above, the “resume playback” icon 41 and the “chase playback” icon 42 may not be displayed in FIG. 4 under the control of the control unit 3.

  Here, in the first and second embodiments described above, the recording / playback apparatus 1 shown in FIG. 1 includes a plurality of video / audio input terminals 12, and an input video / audio switching unit for each video / audio input terminal 12. 5, when a recording processing unit 7, a reproduction processing unit 8 and a recording medium 9 are provided so that a plurality of video / audio signals can be input simultaneously and recorded on the respective recording media 9 simultaneously, the plurality of input video / audios When signals are being recorded simultaneously, on the display screen shown in FIG. 2 or FIG. 4, “chase playback 1”, “chase playback 2”,... ”Icons 24 and 42 may be displayed so as to selectively perform the chasing playback of the desired program being recorded.

  FIG. 5 is a flowchart showing the processing algorithm of the third embodiment of the recording / playback apparatus and recording / playback method according to the present invention. The recording / playback apparatus according to the third embodiment also has the configuration shown in FIG.

  In FIG. 1, when the user operates the playback key of the remote controller, the operation signal is input from the operation signal input terminal 13, and the user instruction receiving unit 4 receives this and notifies the control unit 3 of an instruction to start playback. Upon receiving this notification, the control unit 3 executes the processing algorithm shown in FIG.

  That is, when the recording / playback processing unit 2 is not recording and there is a recorded program that is paused for playback (“no” in S51), the playback processing unit 8 records the playback paused from the recording medium 9. A resume playback start is started to start playback from the position where the program was last paused (S53).

  If the program is being recorded (“yes” in S51), if there is a recorded program that is paused at this time, the control unit 3 is paused by the playback processing unit 8 and resumes the recorded program. And start of chasing playback of the program being recorded (S52).

  The encoded streams of the video / audio signals of the recording program for resume reproduction and the program being recorded for follow-up reproduction from the recording medium 9 are respectively decoded and synthesized by the reproduction processing unit 8 to produce two-screen video / audio. A signal is formed. This two-screen video / audio signal is supplied to the video synthesis unit 10 via the output video / audio switching unit 6. On the other hand, when the control unit 3 receives the notification of the instruction to start playback, the control unit 3 controls the OSD creation unit 11 to create an OSD screen for selecting resume playback and chasing playback. The created OSD screen signal is synthesized with the above-mentioned two-screen video / audio signal by the video synthesis unit 10 and supplied from the video / audio output terminal 14 to a display unit (not shown).

  FIG. 6 is a diagram showing display contents on the display screen of the display unit at this time. 61 is a display area for resume playback video, 62 is a display area for chasing playback video, 63 is a “resume playback” icon, and 64 is a display. “Chase play” icon. The recording / playback apparatus according to the second embodiment also has the configuration shown in FIG. 1. Here, the display screen of the display unit connected to the video / audio output terminal 14 is indicated by reference numeral “60”. Yes.

  In the figure, the display screen 60 of the display unit is divided into two video display areas 61 and 62 by the above-described resume playback recording program, chasing playback recording program, and two-screen video / audio signal. The video of the recorded program replayed in 61 is displayed in the video display area 62, and the video of the program being recorded that has been played back is displayed. At the same time, it is indicated that the video displayed in the video display area 61 at a predetermined location, for example, the upper side, is the video by the resume playback, and this video can be selected. The “play” icon 63 is displayed, and the video displayed in the video display area 62 is displayed in the video display area 61 at a position corresponding to the display position of the “resume playback” icon 63 in the video display area 61. A “chase playback” icon 64 is displayed to indicate that the video is selectable and this video can be selected.

  The user can select either the “resume playback” icon 63 or the “chase playback” icon 64 by a cursor operation on the remote controller. Here, when this arrow-shaped cursor is used, either the “resume playback” icon 63 or the “chase playback” icon 64 can be selected with this cursor. By operating the enter key on the remote control, it is possible to select display of only one of the playback images. For example, when the “resume playback” icon 63 is designated and selected by icon operation with the remote control, the video of the recorded program by resume playback is set to the display state on the entire display screen 60, and “chase” is performed by key operation of the remote control. When the “play” icon 64 is designated and selected, the video of the program being recorded by chasing playback is set to the display state on the entire display screen.

  In addition, as a cursor, the cursor of the form similar to the cursor in previous 1st, 2nd embodiment can be used. In this case, one of the “resume playback” icon 63 and the “chase playback” icon 64 can be selectively designated by operating the left and right keys of the remote controller, and either of them can be selected by operating the enter key of the remote controller. You can choose to display only the playback video.

  Alternatively, instead of displaying the “resume playback” icon 63 and the “chasing playback” icon 64, numbers are displayed in the video display area, and the numbers are displayed on the video display areas 61 and 62 on the operation unit of the remote controller. The video reproduction areas 61 and 62 can be selected by operating the numeric keys corresponding to the keys. For example, when the number “1” is displayed in the video display area 61, the number “2” is displayed in the video display area 62, and the numeric key “1” on the remote control is operated, the video display area 61 is selected. In other words, the video of the recorded program by resume playback is displayed on the entire display screen 60, and when the number key "2" on the remote control is operated, the video display area 62 is selected and displayed. The video of the recorded program by chasing playback is displayed on the entire screen 60.

  In FIG. 5, when no program is recorded and there is no recorded program in the playback pause state, the control unit 3 determines whether or not the control unit 3 performs the determination process in S51 even if the user operates the playback key on the remote controller. End the control with.

  In this way, in this third embodiment as well, when an operation device such as a remote control and a display unit constitute a user interface and a user wants to view a recorded program in a playback pause state, this recording is performed. Without specifying the program directly, it is possible to continue playback and viewing from the position where playback was paused by a simpler operation of the operating device. When viewing is desired, the recorded program can be reproduced and viewed from the beginning by a simpler operation of the operation device without directly specifying the program being recorded.

  Also in the third embodiment, the recording / playback apparatus 1 shown in FIG. 1 includes a plurality of video / audio input terminals 12, and each video / audio input terminal 12 has an input video / audio switching unit 5 and a recording process. When a plurality of video / audio signals are simultaneously input and simultaneously recorded on the respective recording media 9 are provided, the plurality of input video / audio signals are simultaneously recorded. In this case, the display screen 60 can be divided into a display area for video of a recorded program for resume playback and a display area for video for a program being recorded for follow-up playback, and these videos can be displayed simultaneously. A desired image out of these images can be selected and displayed on the entire display screen 60 by the same method as described above. For example, when it is possible to record three recorded programs at the same time, the video of the recorded program by one resume reproduction and the recorded program by three chasing reproductions are displayed on the display screen 60 by operating the reproduction key on the remote controller. Are displayed at the same time.

  In each of the above embodiments, as a matter of course, when a recorded program to be resumed is reproduced to the end, it is removed from the target of resume reproduction, and a program being recorded or designated for chasing playback is designated. When the recorded program being reproduced is put into a reproduction pause state, it becomes a target for resume reproduction.

  As mentioned above, although embodiment of this invention was described, this invention is not limited only to this embodiment. For example, in each of the above-described embodiments, two types of playback program selection modes, resume playback and chasing playback, are used, but three or more types of playback program selection modes to which other playback program selection modes such as “recommended program playback” are also added. It is good.
