Description

  The present invention relates to an information editing / recording system, an information editing apparatus, and an information writing apparatus, and in particular, an edited result obtained by specifying one or more sets of arbitrary playback start positions and corresponding playback end positions of a moving image. The present invention relates to an information editing / recording system, an information editing apparatus, and an information writing apparatus for creating a specified format medium by writing the image information in a medium having a data structure of a specified format.

  A display device capable of reproducing and displaying a moving image is provided, and one or a plurality of designations of an arbitrary reproduction start position (reproduction start time) of the moving image and a reproduction end position (reproduction end time) corresponding thereto are designated. Recording apparatuses such as a DVD (Digital Versatile Disc) recorder having a playlist function that can perform cut editing by setting are widely used. This playlist function uses only edit point information (that is, combination data of a reproduction start time and a reproduction end time paired therewith), and it looks as if the original moving image information has been edited, This is a function for performing playback equivalent to the result of actual editing (deletion, copying, combining).

  There is also a device that writes the edited result according to a specified format to a writable DVD medium by using editing point information generated in the playlist function. This writing device is generally embodied as a media creation device integrated with a device (such as a hard disk device) that stores editing material data such as moving image information in a memory (for example, a hard disk integrated DVD). Recorder).

  This playlist function is also mounted on a camera-integrated VTR (for example, a mobile device such as a video camcorder) using a random access recording medium (semiconductor memory, DVD disk, etc.). In general, the conversion of the format of recorded data in the same medium is not performed. The main reason is that, in general, it is a matter to avoid an operation accompanied by image quality deterioration and loss of a part of original data. Another reason is that there are cases where there is not much room for free space on the media.

  By the way, as a method of passing recorded data to another person, the price of a semiconductor memory card or the like is relatively expensive, so the recorded semiconductor memory card is handed over to another person or copied to the same type of memory card. It is difficult to pass. On the other hand, a large-capacity medium such as a DVD medium is cheaper than a memory card, and it is a common practice to copy recorded data to a DVD medium and pass it to another person.

  However, the method of copying the recorded data to the DVD medium is not used as a method of passing the edited result to another person because it does not pass the edited result in a form that can be reproduced.

  Therefore, an information recording apparatus that records editing point information obtained by a playlist function on a recording medium such as a DVD together with a recorded moving image material has been conventionally known (for example, see Patent Document 1). In the information recording apparatus described in Patent Document 1, a plurality of playlist sets each including a plurality of playlist information defining a reproduction sequence of a plurality of content information, and a plurality of content information in a logical unit of information. First pointer information that designates at least one playlist set corresponding to content information to be reproduced from among a plurality of playlist sets and the first pointer information so as to be reproduced as a certain title Title information including identification information for identifying the playlist information that is a selection candidate in the playlist is recorded on a recording medium.

  However, with the conventional information recording apparatus described in Patent Document 1, the editing point information (a plurality of playlist sets, first pointer information, and identification information) obtained by the playlist function is stored together with the recorded moving image material and the large-capacity medium. However, in order to reproduce the edit point information, a playback device that is exactly the same as the device that recorded the edit point information is required, and has the following problems.

  In other words, the first problem is that a DVD drive and a personal computer (PC) that controls the DVD drive are required to copy the recorded data (usually MPEG (Moving Picture Experts Group) format) onto a DVD medium as a DVD-ROM. Therefore, considering the operation and the relatively expensive price, it is difficult to say that copying is easy.

  In addition, the second problem is that when another person uses the copied data, it is limited to use on the PC, and it is for a non-owner of the PC or a PC that supports playback of moving image data on the disc. That means that the data is not available to non-software owners.

  Furthermore, the third problem is that the method of copying the moving image data and the playlist function created as a result of editing using the playlist function to the DVD medium is the same device as the device that created it. Is necessary for playback of the edited result.

  On the other hand, there is known an information recording apparatus in which recorded data is not simply copied to a DVD medium as it is, but is written in the DVD-Video format by performing authoring (processing such as conversion and reconstruction). Here, the authoring of the DVD-Video format makes it possible to specify various playback operations on the player, including converting the moving image data into the MPEG format so that the DVD player can play back the DVD media. The creation of data in the DVD-Video format. As a result, reproduction on a relatively popular and inexpensive DVD player becomes possible.

  However, the method of converting to the DVD-video format and writing to the DVD medium still has a problem that a PC for performing the same and software for authoring are required. Furthermore, in order to create DVD media with recorded DVD-Video format data with minimal image quality degradation, including these operations, some expertise such as MPEG data, equipment installation skills, and labor In addition, it is not always easy to say that it is easy considering the price.

  The simplest method is to connect the playback output terminal of the camera-integrated VTR to the input terminal of the DVD recorder without using a PC, and dubbing and saving the DVD media in the DVD-Video format by the DVD recorder. However, in this case, MPEG data obtained by imaging with the camera-integrated VTR is once decoded by the camera-integrated VTR, and then encoded again in the DVD-Video format on the DVD recorder. Processing is required and image quality degradation cannot be denied.

  The present invention has been made in view of the above points, and enables editing of material data such as recorded moving image data with a low-cost configuration, and without causing deterioration of image quality, even without special knowledge.

The play list data 108 indicating an arbitrary reproduction start position (reproduction start time) of a moving image or the like based on the above and the reproduction end position corresponding thereto is generated and stored in the memory 103, or the material designation data 109 is generated. In addition, the play list creation designation control unit stored in the memory 103 reads out each data stored in the memory 103 from the memory 103 and sends it to the second device 200 via the external I / F unit 106.

  In FIG. 1, for the sake of simplicity, the first apparatus 100 shows only the configuration related to moving image data, but actually handles still image data, audio data, and even character data. FIG. 2 shows a detailed block diagram of an embodiment of the first device 100. In the figure, the same components as those in FIG. In FIG. 2, a still image decoder 110, an audio decoder 111, an audio output device 112, and a character generation device 113 are also built in the first device 100, and the still image data 114 is stored in the storage device (memory) 103. Audio data 115 is also stored, and disc authoring material designation data 116 corresponding to the material designation data 109 is further stored. The disc authoring material designation data 116 is data for setting association with a designated media format.

  The still image decoder 110 decodes the still image data 114 read out from the memory 103 as necessary, and outputs the obtained still image signal to the image display device 101 to display a still image. The audio decoder 111 decodes the audio data 115 read out from the memory 103 as necessary, and supplies the obtained audio signal to the audio output device 112 such as a speaker to generate sound. The character generation device 113 generates a character signal via the control device 104 and supplies it to the image display device 101 to display characters.

  The moving image data 107, still image data 114, audio data 115, etc. existing in the storage device (memory) 103 in the first device 100 are written via the external I / F or the storage device (memory) 103 itself. May be configured to be detachable, and the moving image data 107, the still image data 114, the audio data 115, and the like may be written in another device.

  Returning to FIG. 1 again, the second device 200 includes a media writing device 201, a control device 202, a media format data temporary storage unit 203, an external interface (I / F) unit 204, and a write start switch (SW). ) 205, the editing device of the present invention. The media writing device 201 writes various information, playlist data, and the like to a predetermined medium (here, a DVD disc) 206 loaded by the control device 202.

  The control device 202 is connected to the media writing device 201, the media format temporary storage unit 203, the external I / F unit 204, and the write start SW 205, and is input from the first device 100 input via the external I / F 204. Based on the transmitted moving image data 107, playlist data 108, material designation data 109, etc., media format data in a predetermined format format (for example, data in the Dvd-Video format format) is generated to temporarily store the media format data 203. Function as a media format data creation unit that temporarily stores data, and reads the media format data from the media format data temporary storage unit 203 and supplies the media format data to the media writing device 201 (here, a DVD disc) It has a function as a media writing control unit for writing the 06.

  The external I / F unit 204 is connected to the external I / F unit 106 in the first apparatus 100 via the cable 300. The write start SW 205 is a switch operated by the user so as to operate the media writing device 201 via the control device 202 when writing media format data to the media (here, DVD disc) 206.

  In the present embodiment, one set or a plurality of sets of reproduction position information that is a pair of the information reproduction start position and the information reproduction end position are designated using the GUI (Graphical User Interface) and the operation SW 105 of the first apparatus 100. Any one or more playlist data out of playlist data 108 including playlist position editing and material data (moving image data 107, still image data 114, audio data 115, etc.) obtained by performing playlist editing. And the material specification data including the selected playlist data, for example, material specification data necessary for DVD authoring, in a form usable by the second device 200 (moving image data 107, still image). The image data 114, the audio data 115, etc.) are stored in the memory 103.

  Thereafter, the second device 200 and the first device 100 are connected via the cable 300. As a result, the material data (moving image data 107 and the like), playlist data 108 and material designation data 109 necessary for DVD authoring in the first device 100 can be read from the second device 200.

  Subsequently, the second device 200 reads the material designation data 109 from the memory 103 in the first device 100 by operating the write start SW 205, reads the material data from the memory 103 according to the designation information, When the read and input material data is the moving image data 107, the control unit 202 uses the media formatter data temporary storage unit 203 to perform reconfiguration such as combining and deleting, or as a menu material in the DVD-Video format. A series of operations is performed by creating burning data of the format according to the above and writing (burning) the burning data to the medium (DVD disc) 206.

  Next, the operation of the present embodiment will be described in more detail. First, the first apparatus 100 performs a preparation process for performing DVD authoring. As a configuration of a DVD-Video format medium (DVD disc) 206, a moving image (referred to as a title) and a menu screen are mainly used. A medium without a menu screen can be created. However, here, it is assumed that a DVD-Video format medium (DVD disc) 206 having a plurality of moving images (titles) and a menu screen is created.

  In the preparation process stage for performing DVD authoring, a moving image material (title) is designated and necessary playlist editing is performed. In the first device 100, a plurality of thumbnails (small reference still images) indicating a plurality of titles of the moving image data 107 to be reproduced by the moving image reproduction decoder 102 are displayed on the image display device (monitor) 101, among them. When the user operates the operation SW 105 to select one thumbnail, reproduction of the moving image data portion indicated by the thumbnail is started.

  Here, the above-mentioned moving image data portion to be played back may be specified as a whole of the original moving image file, but generally there is an unnecessary portion in an image taken with a video camera or the like. I want to specify a movie with unnecessary parts removed. Therefore, it is not necessary to specify the editing start point and the editing end point as a pair (set) by editing the playlist while monitoring the moving image of the moving image data portion to be reproduced by the image display device (monitor) 101. Delete parts or combine other video material.

  FIG. 3 shows an example of a display screen displaying a list of playlist editing results. In the figure, on the display screen 330 of the image display device (monitor) 101, the edit start point (IN point) is address 2 minutes 5 seconds 12 frames and the edit end point (OUT point) is address 2 minutes 18 seconds 23 frames. Shown is a playlist # 002 including a file MOV002 and a file MOV005 having an editing start point (IN point) of address 5 minutes 16 seconds 3 frames and an editing end point (OUT point) of addresses 5 minutes 38 seconds 12 frames. ing. This playlist editing can be arbitrarily created. One or more playlist data 108 as a playlist editing result is stored in the memory 103 of FIG.

  Subsequently, the DVD authoring process is started. First, an operation is performed as to which playlist data is allocated as a title (moving image editing result) in the authoring data from the playlist data 108 stored in the memory 103. This operation is performed according to the display screen of FIG. FIG. 5 shows an example of a display screen on the first device for setting to use the playlist data in the designated media format. In the figure, the display screen 500 of the image display device (monitor) 101 has a number input area 501 for specifying a page number where a title exists in the specified media format, and a page number specified in the number input area 501. A title number input area 502 for designating a title on the designated page, a playlist number 503 used in the designated media format currently set, and the like are displayed.

  Note that arbitrary still image data can be used for the thumbnail indicating the title. In this case, an arbitrary still image file existing in the first device 100 is designated for each thumbnail indicating the title on the menu screen displayed when the DVD disc created by the second device 200 is played back. Then, an operation for storing the information in the memory 103 is performed.

  Subsequently, by operating the operation SW 105, a character string such as the title name displayed on the lower position of the thumbnail on the screen of the image display apparatus 101 shown in FIG. 4 is displayed in the character generation apparatus 113 shown in FIG. And the character code of the character string is stored in the memory 103 as the DVD authoring material data 116, or the page (one of the DVD disc playback menu screens) is stored in the memory 103 as the DVD authoring material data 116. Save the image (still image data). Similarly, the title of the page is input as necessary, and is stored as the DVD authoring material data 116 in the memory 103 as a character code or an image.

  FIG. 4 shows an example of the use of elements on the screen display during playback in the specified media format. In the figure, a screen 400 at the time of reproduction in the designated media format includes a character string 401 representing the page title in the designated media format, title information 402 in the designated media format, and a character string 403 representing the title name. Is displayed.

  The title information 402 is composed of a page (menu) number and a title number in the page. Here, the title information 402 is shown as 2-1, 2-2, 2-3, and the number “2” before the hyphen is the page ( Menu) number, and the numbers “1”, “2”, and “3” after the hyphen indicate the title number in the page (menu), respectively. In the area for displaying the title information 402, after assigning the playlist data to the title on the page (menu), a still image corresponding to the title information is displayed. In addition, in the character string 401 representing the title, a page (menu) number is also represented in addition to the title “Great Race”.

  For example, the moving image scene of the title 2-1 indicated by the title thumbnail defined on the designated media format shown in FIG. 4 is # 002 in the first apparatus 100 as shown in FIG. This means that the video editing result specified in the playlist is assigned. An example of the GUI of the first apparatus 100 for performing this allocation is shown in FIG. In the designated media format used as an example here, there is a number input area 501 for designating a page (menu) number where a title (moving picture) exists, and an edited moving picture indicated by an arbitrary playlist. Can be instructed on this screen as to which title of which page (menu) on the specified media format.

  It is also possible to play background music (BGM) while the menu screen is displayed. In this case, in the first apparatus 100, an audio file in the memory 103 is selected and included in the disk authoring material designation data 116 as data for designating that the audio file is used as the menu BGM material. 103.

  Each piece of data obtained as described above is used as one piece of designated information in the memory 103 as disk authoring material designation data 116 for creating (authoring) a DVD in the DVD-Video format format with the second device 200. Save it. Thus, the preparation process in the first device 100 ends.

  Next, the storage format of the material designation data 109 (disc authoring material designation data 116) will be described. If the material designation data 109 (disc authoring material designation data 116) is created only in the first device 100 and is read only by the second device 200, the storage format is an agreement between the devices. It only has to exist. However, it is not a format that depends only on the first device 100 and the second device 200, but more general, that is, a format that can be created and used by devices other than these devices 100 and 200. Can be used with other devices.

  For that purpose, a form in which the designation information of the material itself indicates the meaning is desirable. An XML (extensible markup language) format can be considered as such a form. This is a mechanism that puts data called a tag indicating the meaning of the data before and after the data body so that the meaning of each data can be understood independently. In accordance with this idea, it is also useful to save each material designation data 109 (disc authoring material designation data 116) in XML format.

  FIG. 6 is used to create data to be written to a medium in accordance with a data structure of a predetermined media format in the second apparatus 200 and is stored in the XML format stored in the memory 103 of the first apparatus 100. An example of the contents of the material designation data 109 (disc authoring material designation data 116) of the designated media format described is shown.

  In this example, a screen for selecting two moving images (titles) on a certain page (menu), its thumbnail image, background image of the page (menu), BGM designation, title title, page title (menu) title The information that specifies is included. Here, <BGM> indicates an audio file selected to be played as BGM during the menu screen display, and <BGP> indicates an image file selected to be displayed as a background image during menu screen display. .

  When the first device 100 finishes creating the designation information data necessary for authoring, the first device 100 and the second device 200 are connected by the cable 300. Here, the “connection” is not limited to the wired connection by the cable 300, and includes all means that can read data in the memory 103 of the first device 100 from the second device 200. For example, a wireless connection that is not physically connected, such as a wireless local area network (LAN), is also included. However, it should be noted that it takes a very long time to read data, that is, a slow data reading speed per unit time is not a practical connection method.

  After the above connection, the designation information necessary for authoring from the memory 103 via the external I / F unit 204, the cable 300, the external I / F unit 106 and the control unit 104 from the control device 202 of the second device 200 in FIG. Playlist data and material designation data 109 (116) and material data such as moving image data 107 are read out, and based on these data, the control device 202 performs authoring, that is, creation of moving image data and menu data. The media format data required for burning consisting of the created data is stored in the temporary storage unit 203.

The designated media format data can be generated and written to the medium (here, DVD disc) 206 in the designated media format by the media writing device 201 provided in the second device 200.

  In addition, the first device 100 having the designated media format setting function and the second device 200 for writing the designated media format can share operation buttons, display devices, etc. that are commonly used for each operation. A system for creating format media can be constructed at low cost. Also, pre-processing such as copying various data in the first device 100 such as data copy to the second device 200 is not necessary, and the memory size of the media format data temporary storage unit 203 in the second device 200 is reduced. It saves and saves preparation time and is useful compared to a single designated media format writing device.

  In addition, on the first apparatus 100 having a moving image recording function and an audio recording function, it is possible to create media in a specified media format by simple operations such as designation and setting of moving image data and audio data generated by itself. Thus, the data can be effectively used.

  Further, text data (eg, date character data, automatically created file name character data, etc.) created by the first apparatus 100 itself, user input text data, etc. are designated based on the designated format as elements of the designated format media. The specified data is stored in a predetermined format, and the second device 200 refers to the specified information of the predetermined format, so that the text data in the first device 100 is also stored in the specified format medium. It can be used as data for creation.

  Note that the write start SW 205 may not be provided in the second device 200 but may be provided in the first device 100, or a write start operation by an infrared remote controller or the like that controls the second device 200 is also possible.
