JP 2002-269899 A

  In general, a moving image playback apparatus uses a random access recording medium or a sequential access recording medium as a recording medium for recording a moving image. It is possible to identify the image frame recorded on the recording medium at the point of time), but when the recording of the video is paused and then resumed during the pause (hereinafter referred to as the recording resumption point) The image frame recorded on the recording medium cannot be identified.

  The above is a problem in the case where the video playback device records the video itself. However, when the video recorded by one video playback device is copied to the other video playback device using two video playback devices. However, a similar problem occurs. That is, when a moving image playback apparatus acquires and copies a moving image transferred from another moving image playback device, the other moving image playback device cannot identify the image frame recorded at the time when the recording of the moving image is resumed. In addition, if the other moving image playback apparatus uses a sequential access recording medium, the image frame recorded at the time of starting the recording of the moving image on the other moving image playback apparatus side cannot be identified.

  When video recording is resumed after being paused, the status or content of the recording target has changed significantly when recording is paused and resumed, or the recording target itself is completely different. It is extremely important to identify the recorded image frame.

  Therefore, in order for the moving image playback device to identify the image frame recorded at the time when the recording of the moving image is resumed, the user once plays or fast-forwards the recorded or duplicated moving image on the moving image playback device, and then causes the display device to From the displayed video, it is necessary to search for a scene (scene) in which the continuity as a moving image is lost, and manually store the address of the recording medium on which the searched scene is recorded in the moving image reproducing apparatus.

  In such a reproduced video, the operation of confirming a scene in which the continuity as a moving image is lost is extremely complicated, and the user is forced to bear a heavy burden. In addition, there is a model in which the address of the recording medium manually stored in the moving image reproducing apparatus by the user is deleted when the power is turned off or the moving image to be handled is changed. In addition, the moving image reproducing apparatus capable of storing a specific address of the recording medium is limited to a type using a recording medium capable of random access.

  The present invention has been made in view of such a problem, and an object of the present invention is related to a plurality of image frames forming a moving image, and date and time information later than the date and time information added to the immediately preceding image frame by a predetermined time or more. It is possible to cope with the editing or heading reproduction of a necessary part by recording on a recording medium so that an image frame to which an image is added or an image frame in the vicinity of the image frame can be identified. It is an object of the present invention to provide a moving image reproducing apparatus that can record a moving image on a recording medium in a state where it is possible to reduce the burden on the user.

  Another object of the present invention is related to an image frame recorded so that the moving image recorded on the recording medium can be identified each time an instruction to skip the moving image is received, or to the image frame. Another object of the present invention is to provide a moving image reproducing apparatus capable of improving the reproducing operation of moving images by adopting a configuration of reproducing from the image frame.

  Still another object of the present invention is to read an image frame recorded so as to be identifiable or an image frame associated with the image frame from a recording medium every time an instruction to output a still image is received. Provided is a moving image playback device that allows a user to easily recognize a scene in which continuity as a moving image has been lost when the output image frame is displayed using a display means by adopting an output configuration. It is in.

  The moving image reproducing apparatus according to the present invention includes recording means for recording a moving image composed of a plurality of image frames to which date / time information is separately added to a recording medium, and reproduces the moving image recorded on the recording medium. In the moving image reproducing apparatus, a specifying unit that specifies an image frame to which date and time information that is later than a predetermined time by the date and time information added to the immediately preceding image frame is specified, and the image frame specified by the specifying unit or the image frame And adding means for adding an identification code to an address at which the recording means records a nearby image frame on a recording medium.

  In the present invention, the image frame to which the date and time information later than the date and time information added to the immediately preceding image frame is added by a predetermined time or more is specified.

  For example, in the case of recording a moving image by itself, after the moving image is recorded on the recording medium, by referring to the date / time information added to each of a plurality of image frames, or the operation of recording or resuming the moving image is performed. By monitoring, an image frame to which date / time information later than the date / time information added to the immediately previous image frame is added by a predetermined time or more is specified.

  In addition, when acquiring and recording (duplicating) a moving image recorded by another moving image playback device, the date and time information added to each image frame, that is, the date and time information added at the time of recording by another moving image playback device is used. By referencing, an image frame to which date and time information later than the date and time information added to the immediately preceding image frame is added by a predetermined time or more is specified from among the plurality of acquired image frames.

  Then, an identification code is assigned to the address at which either the specified image frame or an image frame in the vicinity of the image frame, that is, the specified image frame, or an image frame before and after several frames of the image frame is recorded on the recording medium. Append.

  The image frame specified as described above is the recording start time or the recording resumption time when the moving image playback device records the moving image by itself or when another moving image playback device records the moving image. This corresponds to the image frame recorded in (i.e., the scene in which the continuity as a moving image is lost).

  In order to identify such a scene that has lost its continuity as a moving image, it is only necessary to be able to grasp an image frame corresponding to the scene. Therefore, it is only necessary to add an identification code to an address where not only the specified image frame but also about several image frames before and after the specified image frame are recorded on the recording medium.

  Note that the address here refers to, for example, a hard disk device or an optical disk such as a DVD-R, RW, RAM, etc., which is associated with the time stamp and the order in which the data is recorded when the data is recorded on the disk. This corresponds to the physical address (track number and sector (the former also includes the surface number)) indicating the upper physical position. In the semiconductor memory, the address itself corresponds. In the magnetic tape, the address is changed as the motor rotates. This corresponds to the physical position of the tape running in the reverse direction.

  In the video playback apparatus according to the present invention, a skip playback reception unit that receives a skip playback instruction for skipping playback of a video, and an address to which the identification code is added when the skip playback reception unit receives a skip playback instruction Or playback means for skipping to an address associated with the address and playing back a moving image.

  In the present invention, a skip playback instruction for skipping playback of a video is accepted, and when a skip playback instruction is received, the video is skipped to an address to which an identification code is added or an address associated with the address. Reproduce.

  For example, when an identification code is added to an address where the specified image frame itself is recorded, a moving image is created from the address to which the identification code is added by referring to the identification code when a skip reproduction instruction is received. Skip playback. Therefore, every time a skip playback instruction is received, skip playback (head playback) is started from the scene itself that has lost its continuity as a moving image.

  In addition, when an identification code is added to an address where an image frame several times after the specified image frame is recorded, the identification code is obtained by referring to the identification code when a skip reproduction instruction is received. A video is skip-played from the address where an image frame several times before the image frame recorded at the added address (that is, the specified image frame itself) is recorded, or the address to which the identification code is added. . Therefore, each time a skip playback instruction is accepted, the former is skipped from the scene that has lost its continuity as a movie, and the latter is skipped from the scene immediately after the scene that has lost its continuity as a movie. The Even in the latter case, there is no problem because skip playback is performed from a scene that can be regarded as a scene in which continuity is lost.

  In addition, when an identification code is added to an address where an image frame that is several frames before the specified image frame is recorded, the identification code is identified by referring to the identification code when a skip reproduction instruction is received. Skip video from the address where the image frame (that is, the specified image frame itself) about several frames after the image frame recorded at the address with the code added, or the address with the identification code added Reproduce. Therefore, each time a skip playback instruction is accepted, the former is skipped from the scene that has lost its continuity as a moving image that excludes the previous unnecessary scenes, and in the latter case, the continuity as a moving image is lost. Skip playback is started from the scene just before the scene. Even in the latter case, there is no problem because a scene in which continuity as a moving image is lost immediately after the reproduction is skipped is reproduced.

  In the moving image reproducing apparatus according to the present invention, the recording medium can be randomly accessed, and a still image output receiving unit that receives a still image output instruction for outputting a still image, and the still image output receiving unit is configured to output a still image. An output means for reading out and outputting from the recording medium an image frame recorded at an address to which the identification code is added or an address associated with the address when an instruction is received; And

  In the present invention, a still image output instruction for outputting a still image is received. Here, since the recording medium is a random-accessible recording medium, when a still image output instruction is accepted, the recording medium is recorded at an address to which an identification code is added or an address associated with the address. The image frame is read from the recording medium and output.

  For example, when an identification code is added to the address where the specified image frame itself is recorded, the identification code is referred to when an instruction to output a still image is received, and recorded at the address to which the identification code is added. Output image frame. Thus, each time a still image output instruction is received, the scene itself that has lost its continuity as a moving image is output.

  Also, if an identification code is added to the address where the image frames that are several frames after the specified image frame are recorded, the identification code is referenced by referring to the identification code when a still image output instruction is received. An image frame that is several frames before the image frame recorded at the address to which is added (that is, the specified image frame itself) or the image frame recorded at the address to which the identification code is added is output. Therefore, each time a still image output instruction is received, in the former case, the scene itself that has lost continuity as a moving image is output, and in the latter case, a scene immediately after the scene that has lost continuity as a moving image is output. . In particular, even in the latter case, there is no problem because a scene that can be regarded as a scene having lost continuity is output.

  In addition, when an identification code is added to an address where an image frame about several times before the specified image frame is recorded, by referring to the identification code when a still image output instruction is received, An image frame that is several frames after the image frame recorded at the address to which the identification code is added (that is, the specified image frame itself) is output. Therefore, each time a still image output instruction is received, the scene itself that has lost its continuity as a moving image that excludes several unnecessary scenes immediately before is always output.

  The moving image reproducing apparatus according to the present invention includes recording means for recording a moving image composed of a plurality of image frames to which date / time information is separately added to a recording medium, and reproduces the moving image recorded on the recording medium. In the moving image reproducing apparatus, a specifying unit that specifies an image frame to which date and time information that is later than a predetermined time by the date and time information added to the immediately preceding image frame is specified, and the image frame specified by the specifying unit or the image frame Storage means for storing addresses at which the recording means has recorded neighboring image frames on a recording medium.

  In the present invention, as in the method described above, an image frame to which date / time information that is later than the date / time information added to the immediately preceding image frame by a predetermined time or more is specified. Then, the storage unit stores an address at which either the specified image frame or an image frame in the vicinity of the image frame, that is, the specified image frame or about several image frames before and after the image frame is recorded on a recording medium. To remember.

  In addition, as described above, the storage unit stores the address where not only the specified image frame but also about one of several specified image frames is recorded on the recording medium. This is because in order to identify a scene in which continuity has disappeared, it is only necessary to grasp an image frame corresponding to the scene.

  In the video playback apparatus according to the present invention, the skip playback reception unit that receives a skip playback instruction for skip playback of a video, and the storage unit that stores the skip playback reception unit when the skip playback reception unit receives the skip playback instruction. It further comprises playback means for skipping to an address or an address associated with the address and playing a moving image.

  In the present invention, when a skip playback instruction for skipping playback of a video is received and the skip playback instruction is received, the video is skipped to the address stored in the storage means or an address associated with the address. Reproduce.

  Therefore, every time a skip playback instruction is received, a scene in which continuity as a moving image is lost by referring to the address stored in the storage means, as in the case of referring to the identification code added to the address described above, or Skip playback is performed from the scene immediately before or after the scene. Of course, even in the latter case, there is no problem in skip reproduction as described above.

  In the moving image reproducing apparatus according to the present invention, the recording medium can be randomly accessed, and a still image output receiving unit that receives a still image output instruction for outputting a still image, and the still image output receiving unit is configured to output a still image. An output means for reading out and outputting from the recording medium an image frame recorded at the address stored in the storage means or an address associated with the address when an instruction is received; Features.

  In the present invention, a still image output instruction for outputting a still image is received. Here, since the recording medium is a random-accessible recording medium, when a still image output instruction is accepted, it is recorded at an address stored in the storage means or an address associated with the address. The image frame is read from the recording medium and output.

  Therefore, each time a still image output instruction is received, a scene in which continuity as a moving image is lost by referring to the address stored in the storage means, as in the case of referring to the identification code added to the address described above, Alternatively, a scene immediately after the scene is output.

  According to the present invention, for a plurality of image frames forming a moving image, an image frame to which date and time information later than a date and time information added to the previous image frame is added by a predetermined time or an image frame in the vicinity of the image frame That is, an image frame corresponding to a scene in which continuity as a moving image has disappeared, or an image frame corresponding to a scene substantially immediately before or substantially immediately after the scene can be recorded on a recording medium so that it can be identified. . Therefore, it is possible to record a moving image on a recording medium in a state where it is possible to cope with editing of necessary portions or heading playback.

  Moreover, identification codes or addresses referred to for identifying these image frames can be automatically added to or stored in the corresponding addresses of the recording medium in the former and in the storage means in the latter, respectively. This eliminates the need for the user to perform a manual operation for identifying the specific image frame as described above to the moving image playback apparatus after recording the moving image, thereby reducing the burden on the user. In particular, in the latter case, a part of the recording area of the recording medium for recording a moving image built in the moving image reproducing apparatus can be used as the storage unit.

  Such a moving image recording method is extremely useful for any of a randomly accessible recording medium, a sequential access recording medium, a recording medium built in the moving image reproducing apparatus, or a recording medium detachable from the moving image reproducing apparatus. It is. In particular, when a moving image and an identification code are recorded on a recording medium that can be attached to and detached from the moving image reproducing device, the use environment of the recording medium equivalent to the moving image reproducing device that recorded the moving image is the same as that of other moving image reproducing devices. It can be reproduced, so that versatility can be improved for a recording medium on which a moving image is recorded by the moving image reproducing apparatus, and convenience for a user can be improved.

  According to the present invention, each time a skip playback instruction for skipping playback of a moving image is received, the identification code added to the specific address of the recording medium or the specific address of the recording medium stored in the storage means is referred to. Thus, it is possible to perform skip reproduction from an image frame recorded so as to be identified or an image frame associated with the image frame. This makes it possible to perform skip playback (heading playback) from a scene in which continuity as a moving image has disappeared, or a scene substantially immediately before or after the scene, thereby improving the playback operation of the moving image.

  Such cueing reproduction is applicable to either a random access recording medium or a sequential access recording medium.

  Furthermore, according to the present invention, since the recording medium is a random-accessible recording medium, each time a still image output instruction for outputting a still image is received, an identification code added to a specific address of the recording medium or a storage The image frame recorded so that it can be identified by referring to the specific address of the recording medium stored in the means, or the image frame associated with the image frame is read out from the recording medium and output. Can do.

  Therefore, when the output image frame is displayed using the display means, it is easy for the user to find a scene that has lost its continuity as a moving image that is usually buried and difficult to find, or a scene immediately after the scene. Can be recognized.

  In the following, an embodiment in which the moving picture reproducing apparatus of the present invention is applied to a video recorder that records a moving picture on a hard disk will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration example of a video recorder 20 according to Embodiment 1 of the present invention. The video recorder 20 is configured to be capable of optical communication with a remote control device (hereinafter referred to as a remote control device) 30 that can be remotely operated.

  The video recorder 20 includes a control unit 1 configured by a CPU. The control unit 1 includes a ROM 3, a RAM 4, a tuner unit 5, a selection unit 6, an operation unit 7, a display unit 8, a clock unit 9, a recording processing unit 10, and a hard disk device (hereinafter referred to as HDD) 11 via a system bus 2. The reproduction processing unit 12, the remote control code analysis unit 13, and the output unit 14 are connected to control the operations of these hardware units in accordance with a control program stored in the ROM 3. Data generated when the control program is executed by the control unit 1 is stored in the RAM 4.

  The tuner unit 5 is connected to, for example, an antenna 50 arranged in the direction of the broadcast relay base 80, and an analog television program signal (video signal) transmitted from the broadcast relay base 80 is selected by a user. The designated one-channel television program signal is selected and output to the selection unit 6. Of course, a tuner corresponding to satellite broadcasting or cable television broadcasting may be used.

  In addition to the tuner unit 5, an external input unit 15 is also connected to the selection unit 6. Specifically, the external input unit 15 is a DV terminal conforming to the IEEE (Institute of Electrical and Electronics Engineers) 1394 standard, and is connected to a digital video camera (hereinafter referred to as a DV camera) 60 via a cable. The compressed moving image data in the DV (Digital Video) format transferred from the DV camera 60 is acquired, and the acquired compressed moving image data is output to the selection unit 6. In the figure, the flow of the video signal and the moving image data is indicated by broken arrows.

  Compressed video data in DV format is a format in which a plurality of image frames forming a video are compressed for each image frame, and information such as imaging date and time and the order and output interval for outputting the image frames is added to each image frame. Each piece of information is added on the DV camera 60 side.

  The selection unit 6 has a function of selecting one of the television program signal input from the tuner unit 5 or the compressed video data (DV format) input from the external input unit 15, and the selected television program The signal or compressed moving image data is output to the recording processing unit 10, the reproduction processing unit 12, or the output unit 14.

  The operation unit 7 includes various function keys similar to those of the remote control device 30 necessary for the user to operate the video recorder 20, and receives input of various operation instructions from the user with each key. When each key is pressed by the user, the operation unit 7 sends a control signal corresponding to the pressed key to the control unit 1, and the control unit 1 executes processing corresponding to the acquired control signal.

  The remote control code analysis unit 13 receives infrared light from the remote control device 30 and converts it into a predetermined electrical signal, analyzes the converted electrical signal, receives the code signal transmitted by the remote control device 30, and controls the received code signal Send to part 1. The control unit 1 acquires the code signal transmitted from the remote control device 30 and analyzed by the remote control code analysis unit 13, and executes processing corresponding to the acquired code signal.

  The display unit 8 is configured by a display device such as a liquid crystal monitor or an LED monitor, and displays an operation state of the video recorder 20 and a screen for prompting a user to input an operation instruction. In addition, it is also possible to substitute a part or all of the various function keys of the operation unit 7 by using the touch panel system for the display unit 8.

  The clock unit 9 has a function of notifying the control unit 1 and the recording processing unit 10 of the date and time upon request, and is mainly used for recording a television program by timer reservation.

  The recording processing unit 10 includes an ADC (analog / digital converter), an encoder, and the like. The recording processing unit 10 converts the analog television program signal input from the selection unit 6 into digital moving image data using an ADC, and further encodes and compresses the converted digital moving image data using an encoder. And the converted compressed video data is output to the HDD 11. Of course, when the television program signal demodulated by the tuner unit 5 is MPEG-2 format compressed moving image data, it goes without saying that the ADC and encoder are passed through.

  The recording processing unit 10 converts the compressed moving image data in the DV format input from the selecting unit 6 into compressed moving image data in the MPEG-2 format using an encoder, and outputs the converted data to the HDD 11.

  MPEG-2 format compressed moving image data means that a plurality of image frames forming a moving image are compressed for each image frame and also compressed in the time axis direction, and recording date / time information and image frames are stored in each image frame. This is data in a format to which information such as an output order and an output interval is added, and each piece of information is added by the recording processing unit 10 based on the control of the control unit 1. However, when the compressed moving image data in the DV format is converted into the MPEG-2 format, the imaging date / time information added on the DV camera 60 side before the conversion is updated to the recording date / time information in the recording processing unit 10. However, in the present embodiment, for convenience of explanation, it is assumed that the imaging date / time information remains as it is without being updated.

  The HDD 11 is connected to the recording processing unit 10, and the MPEG-2 format compressed moving image data input from the recording processing unit 10 is associated with a title name (see FIG. 3) in a built-in hard disk (platter) 11 a file. Record in units. Note that the title name is, by default, the recording start date and time, the channel, and the chapter number (see FIG. 2), but can be changed as appropriate by the user operating the remote control device 30.

  A part of the recording area of the hard disk 11a is provided with a recording area for recording the recording management database 11b (see FIG. 2) separately from the recording area for recording the compressed moving image data.

  FIG. 2 is a schematic diagram showing an example of registered contents of the record management database 11b. In the record management database 11b, the compressed video data in the MPEG-2 format recorded on the hard disk 11a is separately provided with a file number for identifying the data, the channel on which the recorded television program of the compressed video data is broadcast, the compression Recording start date and time indicating the date and time when recording of moving image data was started, recording end date and time indicating the date and time when recording of compressed moving image data was ended, a chapter number assigned to each part of the compressed moving image data, and the compressed moving image data Recording information including a recording area on the hard disk 11 a and an input title name indicating a title name appropriately input by the user using the remote control device 30 is registered. The recorded information shown in FIG. 2 is updated as appropriate by the control unit 1.

  The compressed image data with file numbers 1, 4, and 5 in FIG. 2 shows an example in which a television program is recorded by timer reservation. Hereinafter, the compressed image data with the file number m is referred to as compressed moving image data with the file m.

  The compressed image data of file 2 in FIG. 2 shows an example in which a user manually records a television program. There are two types (two stages) of recording start date / time and recording end date / time regarding the compressed image data of file 2, and “1” and “2” are also displayed in the chapter number fields corresponding to the two types of recording start date / time and recording end date / time, respectively. "Is registered.

  This is because when the video recorder 20 recorded the television program of channel 8, the recording was paused once, and the recording start time of the television program (“2004-07-02-19: 00”). ) Until the first recording pause (“2004-07-02-19: 14”) indicates that the chapter number assigned to the partially compressed image data corresponding to the television program recorded is “1”. Partial compression corresponding to a television program recorded from the first recording resumption time ("2004-07-02-19: 16") to the recording stop time ("2004-07-02-19: 28") Indicates that the chapter number assigned to the image data is 2. That is, the compressed moving image data of the file 2 is composed of the above two partial compressed moving image data.

  Further, the compressed image data of the file 3 in FIG. 2 shows an example in which a user manually records (duplicates) a moving image recorded by the DV camera 60 in the video recorder 20. In the channel column in this case, “DV” is registered instead of a numerical value, unlike when a television program is recorded. There are three types (three stages) of recording start date / time and recording end date / time regarding the compressed image data of the file 3, and the chapter number columns corresponding to the three types of recording start date / time and recording end date / time are also “1” to “3”. "Is registered.

  This is because the recording was paused twice when the moving image was recorded on the DV camera 60 side, and the recording start time of the moving image on the DV camera 60 side (“2004-07-04-10: 34”). ) To the first recording pause point (“2004-07-04-10: 52”) indicating that the chapter number assigned to the partially compressed image data corresponding to the moving image recorded is 1 Partial compression corresponding to a movie recorded from the time when the second recording is resumed ("2004-07-04-10: 55") to the second time when recording is paused ("2004-07-04-11: 27") It indicates that the chapter number assigned to the image data is 2, and the recording end time (“2004-07-04-11: 46”) from the second recording resumption time (“2004-07-04-11: 29”). ”Indicates that the chapter number assigned to the partially compressed image data corresponding to the moving image recorded up to“ 3. ”In other words, the file 3 is compressed. Image data includes at least three partial compressed video data.

  As described above, when a numerical value is registered in the chapter number column, it indicates that the compressed moving image data of one file is pseudo-divided by the number of registered maximum numerical values. Of course, when the user manually records a television program or when recording a moving image on the DV camera 60 side, the compressed moving image data of the files 1, 4 and 5 is not paused. As in the case of, the recording start date and time and the recording end date and time are of one type (one stage). In this case, no numerical value is registered in the chapter number column.

  It should be noted that an identification code is added by the control unit 1 to the address of the hard disk 11a in which data indicating the image frame corresponding to each of the recording start time and the recording resumption time among the compressed image data.

  Returning to the block diagram of FIG. 1, the reproduction processing unit 12 includes a decoder, a DAC (digital / analog converter), and the like, and stores MPEG-2 format compressed moving image data recorded on the hard disk 11 a of the HDD 11. The digital video data that has been read out and decoded and decompressed by the decoder is converted into an analog video signal by the DAC and output to the output unit 14. Since the hard disk 11a included in the HDD 11 can be randomly accessed, the recording processing unit 10 and the reproduction processing unit 12 access the hard disk 11a independently to perform recording processing and reproduction processing of compressed moving image data. be able to.

  Further, the reproduction processing unit 12 decodes and decompresses the compressed moving image data in the DV format input from the selection unit 6 by a decoder, converts the decoded and expanded digital moving image data into an analog video signal by the DAC, and outputs an output unit. 14 to output.

  The output unit 14 is connected to the monitor 70 via a video cable and an audio cable, and is an analog television program signal (video signal) input from the selection unit 6 or an analog input from the reproduction processing unit 12. The video signal is output to the monitor 70, and the video (moving image) and the sound related to the video signal are displayed and output on the monitor 70, respectively.

  In the various menu data stored in the ROM 3, a list image of image frames related to the data recorded at the recording start address of each compressed moving image data and each partially compressed moving image data recorded in the hard disk 11a is created. Still image list image creation data is also included.

  Therefore, the control unit 1 displays the identification code under a predetermined condition (for example, when the menu button of the operation unit 7 or the menu button 37 of the remote control device 30 is pressed once as an input of a still image output instruction). The compressed video data recorded on the hard disk 11a and the data recorded at the recording start address of each partially compressed video data are read, and the image frame related to the read data is decoded by the playback processing unit 12. A plurality of still image list images 90 (see FIG. 3) arranged by being reduced and appropriately reduced after expansion are created, and the created still image list images 90 are output to the output unit 14. As a result, the still image list image 90 created by the control unit 1 is displayed on the monitor 70.

  FIG. 3 is a diagram illustrating an example in which the still image list image 90 created by the control unit 1 is displayed on the monitor 70. The still image list image 90 includes still images 91 a to 91 f, title names 92 a to 92 f, and a message field 93.

  The still image 91a is an image obtained by reducing the image frame corresponding to the start of recording of the compressed moving image data of the file 1 shown in FIG. The still images 91b and 91c are images obtained by reducing the image frames corresponding to the start of recording of the partially compressed moving image data assigned with the chapter numbers 1 and 2 constituting the compressed moving image data of the file 2 shown in FIG. . The still images 91d to 91f are images obtained by reducing the image frames corresponding to the start of recording of the partially compressed moving image data assigned with the chapter numbers 1 to 3 constituting the compressed moving image data of the file 3 shown in FIG. . Hereinafter, the partially compressed image data assigned with the chapter number n is referred to as partially compressed image data of chapter n.

  Under the still images 91a to 91f, title names 92a to 92f paired with these are arranged, respectively. For each of the title names 92a to 92f, when the control unit 1 creates the still image list image 90, refer to the recording start date / time column, channel column, and chapter number column shown in FIG. 2 corresponding to each image frame. Thus, the recording start date and time, channel and chapter number are listed in this order. If a title name is registered in the input title name field, the input title name is written in the title names 92a to 92f. 3 indicates that a still image is selected by the operation unit 7 or the cross button of the remote control device 30.

  In the message column 93, a message for prompting the user to input various operation instructions to the video recorder 20 is described, and the content of this message is appropriately changed depending on the operation conditions of the operation unit 7 or the remote control device 30.

  Since the still image list image 90 as described above is displayed on the monitor 70, the user can select desired compressed moving image data or partially compressed moving image data recorded in the video recorder 20, and the selected desired The compressed moving image data or the partially compressed moving image data can be reproduced or deleted as appropriate.

The operation performed by the video recorder 20 having the above configuration will be described below.
First, timer timer recording of a television program by the video recorder 20 will be described. FIG. 4 is a flowchart showing a recording process procedure in the timer reservation of the television program by the control unit 1 of the video recorder 20 according to Embodiment 1 of the present invention.

  First, the control unit 1 obtains the date and time from the clock unit 9 by making a request for the date and time to the clock unit 9 as an input of a recording start instruction, and the acquired date and time is recorded in advance in the timer reservation recording menu. It is monitored whether or not the start date / time has been reached (S1). When the date / time has not reached the recording start date / time (S1: NO), the arrival monitoring is continued. On the other hand, when the date / time has reached the recording start date / time (S1: YES), the control unit 1 performs a subroutine data recording process (S10).

  Hereinafter, the data recording process (S10) will be described. FIG. 5 is a flowchart showing a procedure of data recording processing of the television program by the control unit 1 of the video recorder 20 according to Embodiment 1 of the present invention.

  First, the control unit 1 selects and demodulates a channel designated in advance by the tuner unit 5 and digitizes an analog television program signal (video signal) input through the selection unit 6 by the recording processing unit 10. Then, the data is converted into data indicating an MPEG-2 format image frame (S11). Next, the control unit 1 adds various information such as the recording date and time information and the order of outputting the data indicating the image frame and the output interval to the data indicating the converted image frame (S12). Subsequently, the control unit 1 records data indicating an image frame with various information added to the hard disk 11a of the HDD 11 (S13), and returns the process to the main routine of FIG.

  After performing the data recording process (S10) of the above subroutine, the control unit 1 stores the recording start address of the data indicating the image frame in the hard disk 11a in the RAM 4 (S21). Next, the control unit 1 obtains the date and time from the clock unit 9 by making a request for the date and time to the clock unit 9 as an input of a recording stop instruction, and the acquired date and time is designated in advance in the timer reservation recording menu. It is determined whether or not the recording end date / time has been reached (S22).

  If it is determined in step S22 that the date / time has not reached the recording end date / time (S22: NO), the control unit 1 performs a data recording process (S10) of a subroutine shown in FIG. 5, and then proceeds to step S22. The process of steps S22 and S10 is repeated until it is determined that the date and time has reached the recording end date and time.

  On the other hand, when it is determined in step S22 that the date / time has reached the recording end date / time (S22: YES), the control unit 1 stores the recording end address of the data indicating the image frame in the hard disk 11a in the RAM 4 (S23). . Next, in addition to the recording start address and recording end address stored in the RAM 4, the control unit 1 registers various recording information regarding the recording processing in the recording management database 11b (S24) (for example, files 1 and 4 in FIG. 2). , 5 compressed video data).

  Subsequently, the control unit 1 adds an identification code to the recording start address stored in the RAM 4 among the addresses of the hard disk 11a in which the data indicating the image frame is recorded (S25), and ends the process.

  As described above, each time a timer program is recorded for a television program, an identification code is automatically added to the recording start address after the compressed moving image data is recorded.

  Next, manual recording of a television program by the video recorder 20 will be described. FIG. 6 is a flowchart showing one procedure for manually recording a television program by the control unit 1 of the video recorder 20 according to Embodiment 1 of the present invention.

  First, the control unit 1 monitors the pressing of the recording button (the recording button of the operation unit 7 or the recording button 31 of the remote control device 30) as an input of a recording start instruction (S31). When the recording button is not pressed (S31: NO), the control unit 1 continues to monitor the pressing. On the other hand, when the recording button is pressed (S31: YES), the control unit 1 performs a data recording process (S10) of a subroutine shown in FIG. 5, and then starts recording data indicating an image frame in the hard disk 11a. The address is stored in the RAM 4 (S41).

  Subsequently, the control unit 1 inputs a pause button (a pause button of the operation unit 7 or a pause button 33 of the remote control device 30) as an input of a recording pause instruction, or a stop button (an operation unit) as an input of a recording stop instruction. 7 is monitored (S42).

  If neither the pause button nor the stop button is pressed in step S42 (S42: no press), the control unit 1 performs a data recording process (S10) of a subroutine shown in FIG. 5, and then proceeds to step S42. Then, the processes in steps S42 and S10 are repeated until either the pause button or the stop button is pressed.

  When the pause button is pressed in step S42 (S42: pause button), the control unit 1 records the recording pause address of the data indicating the image frame in the hard disk 11a, that is, the address before conversion (continuity as a moving image). Are stored in the RAM 4 (S43).

  Next, the control unit 1 monitors the pressing of either the pause button as an input of a recording restart instruction or the stop button as an input of a recording stop instruction (S44). If neither the pause button or the stop button is pressed in step S44 (S44: no press), the control unit 1 continues to monitor the press of the pause button or the stop button.

  When the pause button is pressed in step S44 (S44: pause button), the control unit 1 performs a data recording process (S10) of a subroutine shown in FIG. The recording restart address in 11a, that is, the new conversion address (the address where the data indicating the image frame corresponding to the scene in which the continuity as a moving image is lost, that is, the first scene in which the moving image is newly converted) is stored in the RAM 4 (S51), then, the process proceeds to step S42 and the subsequent processing is repeated.

  When the stop button is pressed in step S42 (S42: stop button), or when the stop button is pressed in step S44 (S44: stop button), the control unit 1 stores the data indicating the image frame. The recording end address in the hard disk 11a is stored in the RAM 4 (S52). Next, in addition to the recording start address, the pre-conversion address, the new conversion address, and the recording end address stored in the RAM 4, the control unit 1 registers various recording information about the recording processing in the recording management database 11b (S53) ( For example, refer to the compressed video data of file 2 in FIG. 2).

  The pre-conversion address corresponds to the recording end address of the partially compressed moving image data other than the last partially compressed moving image data in which the chapter number in the compressed moving image data of one file composed of a plurality of partially compressed moving image data is. Similarly, the new conversion address corresponds to the recording start address of partial video data other than the partial compressed video data of chapter 1.

  Subsequently, the control unit 1 adds an identification code to the recording start address and the new conversion address stored in the RAM 4 in the address of the hard disk 11a in which the data indicating the image frame is recorded (S54), and ends the process.

  As described above, each time a television program is manually recorded, an identification code is automatically added to the recording start address and the new conversion address after recording the compressed moving image data.

  FIG. 7 is a flowchart showing another procedure for manually recording a television program by the control unit 1 of the video recorder 20 according to Embodiment 1 of the present invention. Note that the description of the same processing as in the flowchart of FIG. 6 is simplified.

  First, the control unit 1 monitors the pressing of the recording button (S61). When the recording button is not pressed (S61: NO), the monitoring of the pressing is continued, and when it is pressed (S61: YES), it is shown in FIG. A subroutine data recording process (S10) is performed. Subsequently, the control unit 1 stores a recording start address of data indicating an image frame in the RAM 4 (S71), and then adds an identification code to the recording start address stored in the RAM 4 (S72).

  Subsequently, the control unit 1 monitors the pressing of either the pause button or the stop button (S73), and if neither button is pressed (S73: no pressing), the data recording of the subroutine shown in FIG. After performing process (S10), it transfers to step S73 and repeats the process of step S73 and S10 until either of both buttons is pressed.

  When the pause button is pressed in step S73 (S73: pause button), the control unit 1 stores an address before conversion of data indicating an image frame in the RAM 4 (S74).

  Next, the control unit 1 monitors the pressing of either the pause button or the stop button (S75), and if neither of the buttons is pressed (S75: no pressing), the pressing of either of the buttons. Continue monitoring.

  When the pause button is pressed in step S75 (S75: pause button), the control unit 1 performs a subroutine data recording process (S10) shown in FIG. Next, the control unit 1 stores the new conversion address of the data indicating the image frame in the RAM 4 (S81), then adds an identification code to the new conversion address stored in the RAM 4 (S82), and proceeds to step S73. Repeat the process.

  Further, when the stop button is pressed in step S73 (S73: stop button) or when the stop button is pressed in step S75 (S75: stop button), the control unit 1 stores data indicating an image frame. The recording end address is stored in the RAM 4 (S83). Next, the control unit 1 registers various recording information about the recording process in the recording management database 11b (S84), and ends the process.

  As described above, each time a television program is manually recorded, an identification code is automatically added to the recording start address and the new conversion address during recording of the compressed moving image data.

  Next, manual recording of DV-format compressed moving image data by the video recorder 20, that is, copying of a moving image recorded by the DV camera 60 to the video recorder will be described. FIG. 8 is a flowchart showing the procedure of manual recording processing of compressed moving image data in the DV format by the control unit 1 of the video recorder 20 according to Embodiment 1 of the present invention.

  First, the control unit 1 monitors the pressing of the recording button as an input of a recording start instruction (S91). When the recording button is not pressed (S91: NO), the control unit 1 continues to monitor the pressing. On the other hand, when the recording button is pressed (S91: YES), the control unit 1 performs a subroutine data recording process (S100).

  Hereinafter, the data recording process (S100) will be described. FIG. 9 is a flowchart showing a procedure of data recording processing of compressed moving image data in the DV format by the control unit 1 of the video recorder 20 according to Embodiment 1 of the present invention.

  First, the control unit 1 extracts imaging date / time information from data indicating an image frame of the compressed moving image data in the DV format input via the external input unit 15 and the selection unit 6 (S101). It is stored in the RAM 4 so that it can be identified which image frame has been added to (S102). Subsequently, the control unit 1 converts the data indicating the DV format image frame into the MPEG-2 format in the recording processing unit 10 (S103), and records the data indicating the image frame converted in the compression format on the hard disk 11a of the HDD 11. Then, the process returns to the main routine of FIG.

  After performing the data recording process (S100) of the above subroutine, the control unit 1 stores the recording start address of the data indicating the image frame in the hard disk 11a in the RAM 4 (S111). Next, the control unit 1 determines whether or not a stop button has been pressed as an input of a recording stop instruction (S112).

  When it is determined in step S112 that the stop button is not pressed (S112: NO), the control unit 1 performs a subroutine data recording process (S100) shown in FIG. Next, the control unit 1 refers to the RAM 4 and determines whether or not the imaging date / time information of the data indicating the most recently stored image frame has passed a predetermined time or more than the imaging date / time information of the data indicating the most recently stored image frame. That is, when recording a moving image on the DV camera 60 side, it is determined whether or not the recording of the moving image is temporarily stopped or stopped (S121). However, the predetermined time in this case is the shortest time (for example, 1 second) following the operation from the pause to the restart of the moving image recording on the DV camera 60 side and the operation from the stop to the start of moving image recording. It is prescribed.

  If it is determined in step S121 that the predetermined time or more has not elapsed (S121: NO), the control unit 1 proceeds to step S112 and repeats the subsequent processing.

  If it is determined in step S121 that the predetermined time or more has elapsed (S121: YES), the control unit 1 records the data indicating the image frame immediately before the image frame determined to be later than the predetermined time in the hard disk 11a. That is, the address before conversion and the recording address in the hard disk 11a of the data indicating the image frame determined to be later than the predetermined time, that is, the new conversion address are stored in the RAM 4 (S122), and then the process proceeds to step S112. Repeat.

  If it is determined in step S112 that the stop button has been pressed (S112: YES), the control unit 1 stores the recording end address of the data indicating the image frame in the hard disk 11a in the RAM 4 (S123). Next, in addition to the recording start address, the pre-conversion address, the new conversion address, and the recording end address stored in the RAM 4, the control unit 1 registers various recording information about the recording process in the recording management database 11b (S124) For example, refer to the compressed moving image data of file 3 in FIG. 2).

  Subsequently, the control unit 1 adds an identification code to the recording start address and the new conversion address stored in the RAM 4 among the addresses of the hard disk 11a in which the data indicating the image frame is recorded (S125), and ends the process.

  As described above, each time the DV moving image data is manually recorded (duplicated), an identification code is automatically added to the recording start address and the new conversion address after the compressed moving image data is recorded.

  Finally, reproduction of moving image data by the video recorder 20 will be described. FIG. 10 is a flowchart showing a procedure of moving image data reproduction processing by the control unit 1 of the video recorder 20 according to Embodiment 1 of the present invention.

  First, the control unit 1 monitors the pressing of the reproduction button (the reproduction button of the operation unit 7 or the reproduction button 32 of the remote control device 30) as an input of a reproduction start instruction (S131). If the playback button is not pressed (S131: NO), the control unit 1 continues to monitor the pressing of the playback button. On the other hand, when the play button is pressed (S131: YES), the control unit 1 reads the MPEG-2 format compressed moving image data or the partially compressed moving image data from the hard disk 11a and reads it from the recording start address. The moving image data is reproduced by decoding and decompressing the compressed moving image data or the partially compressed moving image data in the reproduction processing unit 12 (S132). As a result, the video signal is output from the output unit 14, and the video and audio based on the video signal are displayed and output on the monitor 70, respectively.

  Next, the control unit 1 inputs a skip reproduction instruction as a skip button (a skip button of the operation unit 7 or a skip button 35 of the remote control device 30), or as an input of a reverse skip reproduction instruction, the reverse skip button (of the operation unit 7). It is determined which of the reverse skip button or the reverse skip button 36) of the remote control device 30 is pressed (S133).

  When it is determined in step S133 that the skip button has been pressed (S133: skip button), the control unit 1 refers to the identification code added to the appropriate address of the hard disk 11a, thereby compressing the moving image data or the portion. The compressed moving image data is read from the hard disk 11a from the next recording start address, that is, the address to which the latest identification code after the address being reproduced is added, and the read compressed moving image data or partially compressed moving image data is reproduced by the reproduction processing unit The video data is reproduced by decoding and decompressing at S12 (S134).

  For example, in the compressed moving image data shown in FIG. 2, when the skip button is pressed during the reproduction of the compressed moving image data of the file 1, the recording is started from the recording start address of the partially compressed moving image data of the chapter 1 of the file 2. The In addition, when the skip button is pressed during the reproduction of the partially compressed moving image data of the chapter 1 of the file 3, the recording is started from the recording start address (new conversion address) of the partially compressed moving image data of the chapter 2 of the same file. The

  When it is determined in step S133 that the reverse skip button has been pressed (S133: reverse skip button), the control unit 1 refers to the identification code added to the appropriate address of the hard disk 11a, thereby compressing the moving image data. Alternatively, the partial compressed video data is read from the hard disk 11a from the previous recording start address, that is, the address to which the latest identification code before the address being reproduced is added, and the read compressed video data or partial compressed video data is reproduced. The video data is reproduced by decoding and decompressing in the processing unit 12 (S135). That is, in this case, playback is started from the recording start address (the latter is a new conversion address) of the compressed moving image data or the partially compressed moving image data being reproduced.

  When it is determined in step S133 that neither the skip button nor the reverse skip button is pressed (S133: no press), or after the processing of step S134 or S135, the control unit 1 displays the compressed video data or the partial compressed video data being reproduced. It is determined whether or not the reproduction is completed (S136).

  When it is determined in step S136 that the reproduction has not been completed (S136: NO), the control unit 1 determines whether or not the stop button has been pressed as an input of the reproduction end instruction (S137).

  When it determines with a stop button not being pressed in step S137 (S137: NO), the control part 1 transfers to step S132, and repeats subsequent processes.

  If it is determined in step S136 that the reproduction has been completed (S136: YES), or if it is determined in step S137 that the stop button has been pressed (S137: YES), the control unit 1 ends the process.

(Embodiment 2)
The configuration of the video recorder 20 according to the second embodiment of the present invention is the same as that of the first embodiment, and the operation performed by the video recorder 20 is different. This will be described below. Note that the RAM 4 provided in the video recorder 20 is a memory that retains stored contents even when the power is turned off.

  First, timer timer recording of a television program by the video recorder 20 according to Embodiment 2 of the present invention will be described. FIG. 11 is a flowchart showing a recording process procedure in timer reservation of a television program by the control unit 1 of the video recorder 20 according to Embodiment 2 of the present invention. Note that step S201 in FIG. 11 and steps S221 to S224 correspond to steps S1 and S21 to S24 in FIG. 4, respectively, and subroutine data recording processing (S10) is shown in FIG. These descriptions are omitted here.

  After the process of step S224, the control unit 1 stores the recording start address stored in the RAM 4 in step S221 in the RAM 4 in association with the file number registered in the recording management database 11b in step S224 (S225). finish.

  Next, manual recording of a television program by the video recorder 20 will be described. FIG. 12 is a flowchart showing a procedure for manually recording a television program by the control unit 1 of the video recorder 20 according to Embodiment 2 of the present invention. Note that steps S231, S241 to S244, and steps S251 to S253 in FIG. 12 correspond to steps S31, S41 to S44, and steps S51 to S53 in FIG. Since the recording process (S10) is shown in FIG. 5, description thereof will be omitted.

  After the process of step S253, the control unit 1 records the recording start address and the new conversion address (the latter is the recording start address of the partially compressed moving image data) stored in the RAM 4 in steps S241 and S251, and the recording management database 11b in step S253. Are stored in the RAM 4 in association with the file number and chapter number registered in (S254), and the process is terminated.

  Next, manual recording of DV-format compressed moving image data by the video recorder 20 will be described. FIG. 13 is a flowchart showing a procedure for manual recording processing of compressed moving image data in the DV format by the control unit 1 of the video recorder 20 according to Embodiment 2 of the present invention. Note that steps S291, S311, S312 and steps S321 to S324 in FIG. 13 correspond to steps S91, S111, S112 and steps S121 to S124 in FIG. Since (S100) is shown in FIG. 9, description thereof is omitted.

  After the processing in step S324, the control unit 1 associates the recording start address and the new conversion address stored in the RAM 4 in steps S311 and S322 with the file number and chapter number registered in the recording management database 11b in step S324. It memorize | stores in RAM4 (S325) and complete | finishes a process.

  Finally, reproduction of moving image data by the video recorder 20 will be described. The procedure of the moving image data reproduction processing by the control unit 1 of the video recorder 20 according to Embodiment 2 of the present invention is the same as the flowchart shown in FIG.

  However, in step S134, the control unit 1 refers to the recording start address and the new conversion address stored in the RAM 4 in association with the file number and the chapter number, so that the hard disk of the compressed moving image data or the partially compressed moving image data is stored. 11a is read from the next recording start address, and the moving image data is skip-reproduced. In step S135, the recording start address and the new conversion address stored in the RAM 4 are referred to in association with the file number and the chapter number. Thus, the point that the compressed moving image data or the partially compressed moving image data is read from the hard disk 11a from the previous recording start address and the moving image data is subjected to reverse skip reproduction is different from the first embodiment.

  In the present embodiment, the control unit 1 presses the menu button of the operation unit 7 or the menu button 37 of the remote control device 30 once under a predetermined condition (for example, as an input of a still image output instruction). 3), the still image list image 90 shown in FIG. 3 is created by referring to the recording start address and the new conversion address stored in the RAM 4 in association with the file number and the chapter number.

  In the present embodiment, the recording start address and the new conversion address associated with the file number and the chapter number are stored in the RAM 4, but the present invention is not limited to this, and the recording (storing) is performed on the hard disk 11a. Also good.

  In the first and second embodiments described above, the recording start address added with the identification code of each compressed moving image data or each partially compressed moving image data or stored in the RAM 4 in order to identify the scene where the continuity as a moving image has been lost. (The latter is a new conversion address) is added to the data indicating each image frame by monitoring the operation of recording start and resumption when recording the compressed moving image data of one file on the hard disk 11a. Although it was specified by referring to the imaging date / time information, the present invention is not limited to this, and the recording date / time information or imaging date / time added to the data indicating each image frame after the compressed moving image data of one file is once recorded on the hard disk 11a. You may specify by referring to information.

  In Embodiment 1 described above, the identification code is added to the recording start address of each compressed moving image data or each partially compressed moving image data on the hard disk 11a. However, the present invention is not limited to this, and immediately before or after these recording start addresses. An identification code may be added to the address. Similarly, in Embodiment 2 described above, the recording start address of each compressed moving image data or each partially compressed moving image data on the hard disk 11a is stored in the RAM 4, but not limited to this, the addresses before and after these recording start addresses are stored. You may memorize | store in RAM4.

  In particular, the address to be accessed for performing skip reproduction and reverse skip reproduction of compressed moving image data and partially compressed moving image data is the case where an identification code is added to the address immediately before or immediately after the recording start address, or immediately before the recording start address or In any case where the immediately following address is stored in the RAM 4, it may be the address itself to which the identification code is added, the address itself stored in the RAM 4, or the recording start address.

  Further, the address to be accessed for creating the still image list image 90 shown in FIG. 3 is the case where an identification code is added to the address immediately after the recording start address, or the address immediately after the recording start address is stored in the RAM 4 The address itself may be the address to which the identification code is added, the address itself stored in the RAM 4, or the recording start address. On the other hand, when an identification code is added to the address immediately before the recording start address, or when the address immediately before the recording start address is stored in the RAM 4, the recording start address is used.

  Further, in the first and second embodiments described above, the moving image playback apparatus of the present invention is applied to a video recorder that records a moving image on the hard disk 11a. Alternatively, the present invention may be applied to a video recorder that records video on a magnetic tape.

  In particular, when the present invention is applied to a video recorder for recording a moving image on an optical disk and an identification code is added to an appropriate address, as in the case of recording on the bird disk 11a, the compressed moving image data of one file is recorded appropriately. In addition, an identification code may be added to the address, and after recording compressed moving image data of a plurality of files on the optical disc, when performing so-called disc finalization processing, the recording added to the data indicating each image frame An identification code may be added to an appropriate address by referring to the date / time information or the imaging date / time information.

  In addition, when applied to a video recorder that records a moving image on a magnetic tape, the address of data indicating a moving image frame recorded at the most recent time after the recording start time of the moving image and the resumption of recording, or the recording pause of the moving image An identification code can be appropriately added to the magnetic tape simultaneously with the recording of the moving image data at the address of the data indicating the moving image frame recorded at the time point and when the recording is stopped. However, it is not possible to add an identification code to the magnetic tape at the same time as the recording of the moving image data at the address of the data indicating the moving image frame recorded at the time when the moving image recording is paused and immediately before the recording stop time. Of course, even in this case, it can be realized by storing a specific address of the magnetic tape in a storage means (for example, a nonvolatile memory).

  Furthermore, in Embodiments 1 and 2 described above, the moving image playback apparatus of the present invention is applied to a video recorder. However, the present invention is not limited to this and may be applied to a DV camera.
