Description

  The present invention relates to a recording / playback apparatus capable of improving the operability by displaying an image related to an image stopped at the previous playback when playing back a captured moving image.

  For example, a video device using a tape-like medium, a DVD disk, a hard disk device, or the like is used as a device capable of recording image information, that is, a moving image, which is represented by public broadcasting such as television broadcasting or satellite broadcasting, or video software. Recording devices as media are already widely used.

  The recorded image information, that is, the moving image, can be reproduced at any time at a user's favorite time on a monitor device capable of displaying a video signal, a general television receiver, or the like according to a reproduction instruction from the user.

  For example, Patent Document 1 describes a digital recording / playback apparatus that creates and displays a list of recorded titles based on title file information when displaying thumbnails.

Note that the recording / playback apparatus described in Document 1 searches for title file information corresponding to a title selected by the user, fast-forwards digital data based on the searched title file information, and allows the user to select a title. It is described that the fast-forward playback of digital data is stopped when the title is changed or the title is determined.
JP 2001-157147 A

  However, in the recording / playback apparatus described in Patent Document 1, when a title is selected, digital data is fast-forwarded and played back. However, if a title takes time to be displayed like a continuous drama, what is the title? It is difficult to identify whether there is.

  Further, in the apparatus of the same document, the image (digital data) of the selected title is fast-forwarded and reproduced to the end. However, for example, in an image file that the user has viewed (reproduced) partway through in the past, the data ahead of the already viewed (reproduced) portion is also reproduced, which is inconvenient for viewing subsequent stories. There are many.

  Further, in the apparatus of the same document, only the fast-forward playback of the title is started, and it is not considered to display how much the actual playback time is.

  An object of the present invention is to search for a portion where reproduction has been stopped immediately before displaying (reproducing) a title list in a recording / reproducing apparatus, and to preferentially reproduce the data immediately before the canceled portion. Thus, it is an object of the present invention to provide a recording / playback apparatus capable of improving user operability and convenience.

  The present invention has been made based on the above problems, and has a recording apparatus that holds image information, and a recording controller that records a history of reproduction of image information up to the previous time in the recording apparatus. The present invention provides a recording / playback device that displays to a user when a list of titles stored in is displayed as thumbnail images based on the point in time when the previous playback was stopped when the title was selected. .

  According to the present invention, when displaying a title list in an apparatus that records and reproduces video (image) information, the title in focus is the part in the title based on the time when the previous reproduction was stopped. By reproducing the data immediately before the time when the previous reproduction was stopped and displaying it in a small window in the list, it is possible to easily remember the story of the title that the user has seen so far. Also, when the title is focused, by displaying the time bar and part information, it is possible to know how long it will take to finish viewing the title.

  Also, in the present invention, since the divided part in the title is displayed for a few seconds and the next part is displayed immediately, the progress of the title is faster than when the entire video is fast-forwarded, and what is the title? Easy to identify.

  Furthermore, in the present invention, if the user has not watched all of the title, since the head part of the part to which the time when the previous playback was stopped and the time immediately before the previous playback was stopped are displayed, It is possible to prevent the story before being viewed (played back) from being played back unintentionally.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram schematically showing elements of a recording / playback apparatus.

  The recording / playback apparatus 1 shown in the figure has a function of storing received broadcast wave data in an HDD (Hard Disk Device) 105 or a DVD disk 106.

  The procedure is as follows. First, a signal wave of a television broadcast is received by the antenna 22, and the tuner 107 demodulates the data of one channel designated by the user into a signal composed of a video signal and an audio signal.

  The video signal and the audio signal are converted into digital signals by the A / D converter 108 and then compressed by the video encoder 112 and the audio encoder 110.

  The compressed digital audio signal and video signal are multiplexed by the multiplexer 111 and converted into, for example, an MPEG system stream.

  The converted MPEG system stream is written to the buffer memory 103 (or 117), and is written to a hard disk (or DVD disk 106) (not shown) of the HDD 105 via the HDD controller 104 (or DVD controller 118).

  The HDD 105 has an area for storing information related to the title in addition to an area for storing the title raw data. In the title, there are parts that separate several titles. The part is either manually set during recording or automatically set based on video information (which is to be recorded). The parts are separated at arbitrary timing based on the start position of various information such as commercials and preview images included in a moving image (content) such as a movie or a series drama, or time information.

  When the part is set manually, the remote controller receiving unit 101 receives the timing at which the part is set, generates information by the part dividing module 102 via the user I / F 119, and the HDD controller 104 (or DVD controller 118). Is used to write to the HDD (or DVD disk).

  When the part is automatically set, the part is set by the automatic part generation module 109 from the audio information and video information from the audio encoder 110 and the video encoder 112, and from the part division module to the HDD or Information is written to the DVD.

  The format of the information written at this time is shown in FIG.

  For example, each title is related to title information 31, information 32 indicating whether or not the title has been viewed to the end, time 33 when the title was last played back, information 34 about the part, and playback time indicated by the part. Information 35 is included at least.

  In order to reproduce the recorded title, the remote control receiving unit 101 receives an instruction from the user and selects a title to be read to the user I / F 119.

  The user I / F 119 issues a title or part read instruction to the HDD controller 104 or the DVD controller 118.

  The title or part to be read is transferred to the multiplexer / demultiplexer 111 via the buffer memory 103 or 117, and demultiplexed (that is, the multiplexed signal is separated). The demultiplexed (separated) video signal and audio signal are sent to the video decoder 113 and the audio decoder 116, respectively, and decoded.

  The decoded video signal and audio signal are converted into an analog television signal by the D / A converter 115 and reproduced (displayed) on the external television monitor 21 via the graphic controller 114.

  When the user instructs display of a data list by a “reproducible data list display button” of a remote controller (remote controller) (not shown), the GUI display module 120 is used to display on the television monitor 21 (State in FIG. 3). The GUI of the reproducible data list is displayed (as will be described later by 1).

  If the user previously displayed the title list (in the screen display example shown in FIG. 11), first, the user is not focused (not selected so far, that is, the cursor has not been moved). The title information 31 of the title “44” is acquired, and the information is displayed in the information display space “46 (see FIG. 11)”. Further, data from the start of the title “44” until a few seconds later is captured, and the images (described later with State 21 in FIG. 3) are displayed in order on the small window 45 of the display screen of the monitor device 21.

  Next, the title information 31 of the title 43 in focus, the information 32 indicating whether the content has been viewed to the end, the time 33 when the previous playback was stopped, the information 34 of each part, and the time information 35 of each part are acquired from the HDD 105. Then, data is sent to the GUI display module 120 via the user I / F 119 (State 31 in FIG. 3).

  Next, using the acquired “last playback stop time and title information” and “chapter information”, the time bar (shown in FIG. 11) is displayed as indicated by “47”. (State 41 in FIG. 3).

  If there is one or more parts in the title and the title has not been viewed to the end, first, the part number to which the playback stop time belongs is obtained from the time information 35 of each part (FIG. 5). State 51).

  Subsequently, data for the first few seconds from the part 1 to the part number to which the last playback stop time is played back and displayed as a “thumbnail image” in the small window “41” (State 61 in FIG. 7). .

  If the data has been played back to the part to which the previous playback stopped, and there is no previous playback stop within a few seconds from the beginning of the part, the data several seconds before the last playback stop Is displayed (State 71 in FIG. 7).

  Thereafter, the index value of the part to be reproduced is returned to “1” (N = 1) (State 81 in FIG. 7), and reproduction of similar data is repeated.

  When the user moves the focus, data after a few seconds from the start of the title before moving is captured and displayed on the small window 41. Thereafter, the time information 32 when the previous playback of the moved title was stopped and the part number information of the time when the previous playback was stopped are acquired again (State 31 in FIG. 3).

  When the reproduction of the title is selected, the selected title is reproduced from the time when the previous reproduction was stopped (State 56 in FIG. 6).

  When the user instructs to end the display of the title list, the display of the title list is ended (State 66 in FIG. 6).

  On the other hand, if one or more parts exist in the title and the title has already been viewed (played) to the end, the data for the first few seconds of the part from part 1 to the last part number is played back Then, it is displayed in the small window 41 (State 62 in FIG. 8).

  When data has been reproduced up to the last part, the index value of the part to be reproduced is returned to 1 (N = 1) (State 72 in FIG. 8), and similar data reproduction is repeated.

  If there is only one part in the title and the title has not been viewed (reproduced) to the end, the data that has passed for a certain period from the beginning is reproduced for several seconds and displayed in the small window 41 (FIG. 9). State 63).

  If the elapsed time reaches the break immediately before the last playback stop time, and if the last playback stop time does not exist within a few seconds of the previous break, the data several seconds before the last playback stop time Is displayed in the small window 41 (State 73 in FIG. 9).

  Thereafter, the reproduction time is returned to “0” (State 83 in FIG. 9), and reproduction of similar data is repeated.

  If there is only one part in the title and the title has already been viewed to the end, the data that has passed for a certain period of time from the beginning is reproduced for a few seconds and displayed in the small window “41” (State in FIG. 10). 64).

  When the elapsed time reaches the end, the reproduction time is returned to “0” (State 74 in FIG. 10), and the reproduction of similar data is repeated.

  If the part list was previously displayed, as shown in FIG. 12, information on the part “54” that is not in focus is acquired and displayed in the display field “55” (data several seconds after the start) Is captured and displayed in the small window “53” (State 25 in FIG. 4).

  The title information 31 including the focused part “52”, the part information 34, and the time information 35 are acquired from the HDD 105 (State 35 in FIG. 4), and the part exists in any part of the time bar. In order to indicate this, the position “56” of the focused part is displayed on the time bar (FIG. 12) (State 45 in FIG. 4).

  Thereafter, the first few seconds of the part are reproduced and displayed in the small window “51” (State 55 in FIG. 4). When the reproduction is completed, the same reproduction process is repeated.

  When the focus is moved (returning to State 25 in FIG. 4), the data of several seconds after the start of the source part is captured, displayed in a small window, and the time of the part to which the focus is moved Get information and title information.

  On the other hand, when playback of the part is selected, playback is performed from the beginning of the part (State 65 in FIG. 4).

  If the user instructs the end of the display of the part list, the display of the part list is ended (State 75 in FIG. 4).

  As described above, according to the present invention, it is possible to view the part of the part that has been viewed so far and the data up to just before the time when the previous playback was stopped through the small window displayed together with the title list on the display screen. As a result, the user can watch the continuation of the title after remembering the part that the user has seen so far.

  Also, in the present invention, since the divided part in the title is displayed for a few seconds and the next part is displayed immediately, the progress of the title is faster than when the entire video is fast-forwarded, and what is the title? Easy to identify.

  Furthermore, in the present invention, if the user has not watched all of the title, since the head part of the part to which the time when the previous playback was stopped and the time immediately before the previous playback was stopped are displayed, It is possible to prevent the story before being viewed (played back) from being played back unintentionally.

  Furthermore, in the present invention, since a time bar is displayed at the same time as selecting a title, it is possible to know how long it will take to finish viewing the title.

  Note that the present invention is not limited to the above-described embodiment, and various modifications or changes can be made without departing from the scope of the invention at the stage of implementation. Further, the individual embodiments may be appropriately combined as much as possible, and in that case, the effect of the combination can be obtained. For example, there is provided a recording / playback apparatus that displays a moving image in a small window from the previous title when a series drama is about to be played and the title has never been viewed (not viewed).
