Description

  The present invention relates to a data processing apparatus and method for searching video / audio data or audio data recorded in advance in a storage device such as a video tape, DVD, or hard disk drive (HDD).

  In recent years, with the increase in capacity of storage devices, it has become possible to store a large amount of video / audio data. However, it is not easy to find target video / audio data from a large amount of stored video / audio data.

  In addition, in order to search video / audio data in a randomly accessible storage device such as a hard disk, the user must search while checking the video / audio one by one by fast-forwarding and rewinding in the same way as with videotapes. become.

Therefore, a method for easily moving from a large amount of video / audio data to a desired reproduction position has been proposed. For example, as in Patent Document 1, it is a method of performing rewinding and fast-forwarding in units of scene changes. On the other hand, there are generally video / audio data processing apparatuses that have the same function (also referred to as chapters) as video / audio data, taking advantage of the possibility of random access. When such an apparatus is used, the user can move the reproduction position to the bookmark position set by the user.
JP 2000-333117 A

  It is not easy to find desired data from a large amount of video / audio data using a conventional fast forward / rewind function.

  In addition, in the method of marking to play immediately from the target position, the user must mark the necessary place one by one.

  Also, with the method of moving the playback position in units of scene changes, it is not possible to move to a location where no scene change has occurred.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a data processing apparatus and method for easily searching for desired video / audio data or audio data.

  The present invention relates to a data processing device for searching video / audio data or audio data using a search key, search key storage means for storing the search key, and a method for performing the search. An input means having a forward jump button and a backward jump button, and when the forward jump button is pressed, the position is a future position from the current playback position of the video / audio data or audio data, and is stored. The stored search is a position that is past the current playback position of the video / audio data or the audio data when the backward jump button is pressed and the position matching the search key is searched. Jump processing means for searching for a position matching the key, and jumping to the searched position to reproduce the video / audio data or audio data Reproduction means that a data processing apparatus characterized by having a.

  According to the present invention, a search key that is a feature amount to be used for a search is stored in advance, and then a jump function for moving a playback position to a jump point generated from a search result by the search key is used. The user can easily find a desired playback position without manually setting a jump point. In addition, the time for finding a desired reproduction position can be shortened as compared with a function using conventional rewinding or fast-forwarding.

  Embodiments of the present invention will be described with reference to the drawings.

  In this specification, “video / audio data” refers to data including both image data and audio data, and “audio data” refers to sound-only data having no image.

[First Embodiment]
The video / audio data processing apparatus according to the first embodiment will be described with reference to the drawings.

(1) Configuration of Video / Audio Data Processing Device FIG. 1 is a block diagram of the video / audio data processing device according to this embodiment. In addition, the arrow in a figure only shows the flow of data.

  The video / audio data recording unit 101 records video / audio data, and is composed of, for example, a program recorded from a broadcast program or distributed content. Examples of the device of the video / audio data recording unit 101 include a video tape, CD, DVD, HDD, flash memory, and the like. It is assumed that the video / audio data is recorded by being divided into recorded units or units specified by the user. The video / audio data divided in this way is referred to as a “file” in this specification. When reproducing the video / audio data, the user selects a file to be reproduced.

  The reproduction unit 106 reads the video / audio data from the video / audio data recording unit 101 and passes the video / audio data to the display unit 108 and the speaker 109. The reproduction unit 106 holds information about a file to be reproduced and a position where the reproduction is performed.

  The search unit 103 reads the search key from the search key database 102 and searches for the position of the video / audio data that matches the read search key with respect to the video / audio data recorded in the video / audio data recording unit 101. .

  The jump processing unit 105 controls the entire jump process, generates a jump point from the search result of the search unit 103, instructs the playback unit 106 to move the playback position, and jump processing UI (user interface). Information necessary for the display unit 107 is passed.

  The jump processing UI display unit 107 passes the contents to be displayed to the display unit 108 and displays a UI screen to the user.

  The search key database 102 stores search keys used for search. An example of recorded information is shown in FIG.

  The search key number 1101 is a unique number assigned to each search key, and the name 1102 is a name assigned to the search key. A feature quantity 1103 is a feature quantity used by the search unit 103 for search. Other data 1104 is text, an image, a moving image, etc. used when displaying a search result.

  A specific example of the feature quantity 1103 is not illustrated because it depends on the search unit 103. Since other data 1104 also depends on the data actually recorded, no specific example is shown here. The search key number 1101 and the feature quantity 1103 are essential, and the name 1102 and other data 1104 may or may not exist.

  In this specification, it is assumed that the search key is recorded in advance in the search key database 102 regardless of the type of search key setting method. Of course, the search key created by the user, the search key obtained by the user, and the like can be registered in the search key database 102. Regardless of the type of search method used by the search unit 103, when the searched video / audio data and one or more search keys are input to the search unit 103, the matched search key and the matched video / It is only necessary to output the position of audio data.

  The input unit 104 is a part that processes input from the user, and is configured by a remote controller (remote controller) as shown in FIG. In this embodiment, the input unit is a remote controller for the sake of simplicity of explanation. However, the input unit need not be a remote controller, and a mouse, a keyboard, or the like may be the input unit 104. 2 may be added to serve as an input unit, or an input device connected to the video / audio data processing device by wire may be the input unit.

  In FIG. 2, 201 is a button for starting playback, 202 is a button for stopping playback, and 203 and 204 are buttons for performing operations similar to conventional rewind and fast-forward, respectively. 205 and 206 Are a backward jump button and a forward jump button. The forward jump button 206 and the backward jump button 205 are buttons mainly used in the description of the present embodiment. The forward jump button 206 and the backward jump button 205 may be collectively referred to as “jump buttons”.

  When the video / audio data recorded in the video / audio data recording unit 101 is recorded after being encoded by MPEG or the like, it is necessary to decode the data read from the video / audio data recording unit 101. In this case, in FIG. 1, it is assumed that the decoding unit that performs this decoding is included in the video / audio data recording unit 101 or the search unit 103 and the reproduction unit 106.

(2) Operation when the forward jump button 206 is pressed An operation when the forward jump button 206 of the remote controller is pressed will be described with reference to FIG.

  Note that “front” refers to a position in the future from the current position, and “rear” refers to a position in the past from the current position. In this specification, the forward jump button or the backward jump button operates only when the file can be specified. In other words, in a situation where no file is specified, no operation is performed when the forward jump button or the backward jump button is pressed.

  If the video / audio data recording unit 101 handles a recording medium on which video / audio data is sequentially recorded, such as a video tape, the video / audio data is always inserted into the video / audio data processing device. The file is in a specific situation. On the other hand, in the case of a recording medium that performs random access such as an HDD, a situation in which a file is selected, a situation in which a file is being reproduced, a file is being played back, or paused can be said to be a situation in which the file is specified. In the following, for simplicity of explanation, only the case where the file is being played back will be described, but the same operation can be performed if the file can be specified.

  When the forward jump button 206 is pressed, the input unit 104 causes the jump processing unit 105 to start a process of performing a forward jump with a message 301.

  Upon receiving the message 301, the jump processing unit 105 acquires information (hereinafter referred to as a file name) specifying the file currently being reproduced from the reproduction unit 106 and the position of the current reproduction from the reproduction unit 106. If the file is selected but not played back, for example, the start time of the file may be returned.

  Next, the jump processing unit 105 notifies the search unit 103 by a message 303 to search for video / audio data ahead of the current position of the file currently being reproduced.

  Upon receiving the message, the search unit 103 acquires all the search keys registered in the search key database 102 with the message 304, and further acquires video / audio data to be searched with the message 305 from the video / audio data recording unit 101. Then, the search is performed on the video / audio data acquired by the message 306.

  In FIG. 3, it is written that the search is executed after all the data to be searched is acquired. However, the search may be repeated after being read a little. The search process is performed in order from the current playback position, and ends when it matches any one of the acquired search keys.

  The result of executing the search is passed to the jump processing unit 105.

  When a location that matches the search key is found, the search result includes a search key number 401 that matches as shown in FIG. 4 and a discovery location 402 that is location information that matches the search key. If no search key matches, the search result contains no information. Since the search ends when one location that matches the search key is found, the search result includes at most one set of the matched search key number and discovery position.

  If the search result includes a result, the jump processing unit 105 generates a jump point using the message 307 based on the received search result. In this embodiment, as shown in FIG. 24, the discovery position and the search key number are simply replaced from the search result.

  The jump processing unit 105 notifies the playback unit 106 of a message 308 with information related to the jump destination position, and the playback unit 106 moves the playback position. If playback is in progress when the jump button is pressed, playback starts from that position after the playback position has been moved. If it is paused when the jump button is pressed, playback is not started after the playback position is moved, and the pause state is entered at that position, and a still image at that position is displayed on the display unit 108.

  Next, the jump processing unit 105 sends a message 309 to which the jump point information is added to the jump processing UI display unit 107 in order to notify the user that the jump has been made. In this embodiment, the name of a search key that can be acquired from the search key database 102 is sent as jump point information.

  Upon receiving the instruction, the jump processing UI display unit 107 generates a screen indicating that the jump has been successful, and notifies the display unit 108 to display the message 310. Here, the name of the search key is displayed as an example.

  The display unit 108 displays the video generated by the jump processing UI display unit 107 on the video data being reproduced. An example of displaying this is shown in FIG. Like the text 502, the jump result and the name of the search key are displayed. When nothing is included in the search result, a display indicating that the jump could not be performed can be displayed on the display unit 108 through the jump processing UI display unit 107 as shown in FIG.

(3) Operation when the backward jump button 205 is pressed When the backward jump button 205 in FIG. 2 is pressed, an operation similar to that when the forward jump button 206 is pressed is performed.

  The first difference is the video / audio data to be searched and the search direction. When the backward jump button 205 is pressed, the data behind the current position is moved backward from the current reproduction position. The search is performed in order toward.

  The second difference is an image generated by the jump processing UI display unit 107. In the example of FIGS. 5 and 6, “front” of the text 502 and text 602 is changed to “rear”. Become.

  A third different point is a case where reproduction is performed after backward jump. Assuming that the jump point at the position jumped backward is the jump point A, when the backward jump button 205 is further pressed after reproduction for a predetermined time or more, the jump is made to the jump point A jumped earlier. On the other hand, when the backward jump button is pressed when the playback time from the jump point A is within a certain time, a jump point behind the jump point A is searched and jumped to that jump point.

  By doing so, it is possible to jump backward one after another by continuously pressing the backward jump button 205, and by repeatedly pressing the backward jump button 205 at intervals, the same portion can be repeated many times. The operation of reproduction can be easily performed.

(4) Operation when the jump button is continuously pressed If the user presses the jump button again while the jump processing unit 105 is performing processing, the jump is performed once at the same time as the number of times the button is pressed.

  When the messages 302 to 306 are being processed, the jump processing unit 105 stores the number of times the jump button has been pressed, and after the processing of the messages 302 to 306 is completed, the number of times matching the search key is determined. Search until you find it.

  If the jump button is pressed during the generation of the jump point in message 307, the generation of the jump point is stopped, or after the generation is completed, the process returns to message 303 again to start the search.

  If the jump button is pressed during movement of the playback position in message 308, the movement process is interrupted or the movement process ends, and then the process returns to message 303 and the search is started again.

  When the forward jump button 206 is pressed many times and the backward jump button 205 is pressed before the end of the jump operation, the count may be reduced by the number of times the backward jump button 205 is pressed. it can. The same applies to the reverse case.

  When the jump button is kept pressed, it is possible to perform the next jump operation as soon as the jump process is completed. In this operation, it is also possible to jump to a certain number of jump points instead of jumping to the next jump point.

(5) Jump across files Jumps across files can be executed if they can be ordered according to the recording time. Here, a case where recording times are used for ordering will be described as an example.

  When the forward jump button 206 is pressed, the search is executed. If no part matching the search key is found after reaching the end of the file, the search is started from the beginning of the next file. The “next file” is a file recorded at a time closest to the recording time of the currently selected file and later than the recording time of the currently selected file. In this way, a plurality of files can be searched one after another only by operating the jump button.

  If the file is grouped, it is within the group to which the selected file belongs, and is closest to the recording time of the currently selected file, and from the recording time of the currently selected file. The file recorded at a later time will continue to be searched as the next file. The search can be terminated when there is no next file to search.

  When the backward jump button 205 is pressed, an operation reverse to the above may be performed.

  In this way, for example, if a group in which only files that record news programs are collected is created, it becomes possible to execute a search in the order in which the news programs are recorded. As a result, it is possible to search one after another as if a plurality of news programs were recorded continuously.

(6) Effects of the First Embodiment As described above, according to the present embodiment, the search using the search key and the movement processing of the playback position are automatically performed only by using the forward jump button 206 and the backward jump button 205. The playback position can be easily moved to the target location.

[Second Embodiment]
The second embodiment is different from the first embodiment in that the jump destination is displayed on the jump processing UI display unit 807 in FIG. 8 so that the user can know the jump destination information before executing the second and subsequent jumps. The information is displayed.

(1) Configuration of Video / Audio Data Processing Device FIG. 8 is a block diagram of the video / audio data processing device according to this embodiment.

  A difference from FIG. 1 is that a representative screen generation unit 810 for generating a representative screen used by the jump processing UI display unit 807 is added.

  FIG. 7 shows an example of an image generated by the jump processing UI display unit 807 in this embodiment.

  In the bar 705, marks 706 to 711 are drawn as marks representing search results.

  The top position of the bar 705 represents the top position of the file currently being reproduced, and the bottom position represents the end position.

  A mark 706 represents the position that is currently being reproduced, and marks 707 to 711 represent the positions of searched jump points generated from the search results.

  These marks are not displayed for the parts that have not been searched. In order to indicate a portion where the search has not been executed, the color of the bar 705 may be changed only for that portion.

  When the forward jump button 206 is pressed, the jump is first performed, and then the jump point information display area 702 displays information of the jump point jumped at that time and some jump points ahead.

  When the backward jump button 205 is pressed, the jump is first performed, and then the jump point information display area 702 displays information of the jump point jumped at that time and some jump points behind the jump point.

  Note that after jumping by pressing the forward jump button 206, information on the jump point jumped may not be displayed, but only information on the jump point ahead of the jump point may be displayed. Similarly, when the backward jump button 205 is pressed, only information on the jump point behind the jumped jump point may be displayed.

  In FIG. 7, three jump point information display areas 702 are displayed as an example, but any number can be displayed. In the case of 0, the jump processing UI display unit 807 displays only the bar 705 and the marks 706 to 711. Conversely, the bar 705 and the marks 706 to 711 are not displayed, and it is also possible to display only the jump point information display area 702 and what is displayed inside it. When there are a plurality of jump point information display areas 702, the jump point position is displayed in the lower direction as it is located forward.

  In the jump point information display area 702, the representative screen generated from the video near the jump point is displayed in the representative screen display area 703. In the character information display area 704, for example, the name of the matched search key is displayed. When an image or a moving image is attached to the search key, an image is displayed as in the case of an image 712, and a moving image is reproduced.

  The jump points displayed in the jump point information display area 702 are distinguished from other marks by changing their shapes and colors such as marks 707 to 709.

  In this way, the user can grasp the position of the displayed jump point information in the file. In FIG. 7, the types of hatching are changed for the sake of convenience. The shape of the mark need not be a rectangle, and may be an ellipse, a triangle, an arrow, or an icon.

(2) Operation when the forward jump button 206 is pressed The operation when the forward jump button 206 and the backward jump button 205 are pressed to generate a UI screen as shown in FIG. 7 is different from that of the first embodiment. . The operation in this embodiment when the forward jump button 206 is pressed will be described with reference to FIG.

  When the user presses the forward jump button 206, the input unit 802 sends a message 901, and the jump processing unit 805 starts the forward jump process.

  The jump processing unit 805 acquires from the playback unit 806 the file name of the file currently being played back and the current playback position based on the message 902. If the search has not been completed, the search unit 803 is notified by a message 903 to execute the search for the video / audio data ahead of the current position of the file currently being reproduced.

  Thereafter, the jump processing unit 805 waits until the search result is notified by the message 907 from the search unit 803.

  The search unit 803 acquires all the search keys from the search key database 802 and executes a search using all the search keys for the video / audio data of the designated file. The search range may be the entire file, or the search may be terminated when a search result necessary for the display in FIG. 7 is obtained. Further, as will be described later, the search result may be passed by a message 907 when one search result is obtained. The search result is configured as shown in FIG. 10, and the search key number 1001 and the discovery position 1002 that match each other are recorded. This is passed to the jump processing unit 805 by a message 907 as a search result.

  In response to the message 908, the jump processing unit 805 generates a jump point from the acquired search result. FIG. 25 shows an example of a conceptual diagram of generated jump points. In the present embodiment, the search key number 1001 and the discovery position 1002 in FIG. When the search unit 803 returns the result in the form of FIG. 25, no particular processing is necessary.

  The jump processing unit 805 searches for a jump point that is ahead of the current playback position and is closest to the current playback position, and notifies the playback unit 806 with a message 909 to move to the jump point.

  The playback unit 806 moves the current playback position to the position of the specified jump point. If playback is in progress when the jump button is pressed, playback starts from that position after the playback position has been moved. If it is paused when the jump button is pressed, playback is not started after the playback position is moved, and the pause state is entered at that position, and the still image at that position is displayed on the display unit 808.

  Next, the jump processing unit 805 sends a message 910 together with the jump point information to the jump processing UI display unit 807 in order to present information regarding the jump point to the user.

  The jump processing UI display unit 807 notifies the representative screen generation unit 810 by a message 911 to generate a representative screen to be displayed in the representative screen display area 703 of FIG. The jump point information to be displayed in the jump point information display area 702 is also passed along with the message 911.

  The representative screen generation unit 810 acquires the video at the jump point from the video / audio data recording unit 801 by using the message 912, and the representative screen generation unit 810 generates the representative screen by using the message 913 from this information.

  Next, in order to display the search key information, the search key database 802 is accessed by the message 914 to acquire the name of the search key and the like.

  A screen as shown in FIG. 7 is generated by the message 915 from the data acquired as described above, the generated screen is sent to the display unit 808 by a message 916, and the display unit 808 displays it superimposed on the screen being reproduced.

  In this embodiment, the jump processing unit 805 keeps information on the jump point unless the file being played is changed. Accordingly, when the user presses the forward jump button 206 when the current reproduction position is in the searched section, the operation closest to the current reproduction position is performed without performing the operations 903 to 908 in FIG. You can jump to the jump point.

  FIG. 7, which is a screen displayed by the jump processing UI display unit 807, is updated whenever the forward jump button is pressed, and information on the jump position and the jump point ahead is always displayed on the screen. .

  If it is desired to display more information on the next jump point, the jump point information may not be displayed.

  The screen displayed by the jump processing UI display unit is not automatically displayed when a predetermined time has elapsed since it was displayed, and the user does not need to perform an operation to turn off the display. However, it can be erased by a user operation such as pressing an arbitrary button, or can be continuously displayed.

  Although only the forward jump button has been described above, when the backward jump button is pressed, the jump direction is changed and the other operations are performed in the same manner.

(3) Operation when the jump button is pressed during the operation When the jump button is pressed during the operation based on the message 902 to the message 916, the number of times the button is pressed during the processing based on the message 902 to the message 908 805 counts, and after a series of processing from message 902 to message 908 is completed, the processing starting from message 902 is repeated as many times as the jump button is pressed.

  If the jump button is pressed during the operation following the message 909, the process returns to the message 909 after each process is interrupted or ended, and the jump position can be moved by the number of times pressed again. That is, after the playback position is moved by the number of times the jump button has been pressed in the processing of message 909, playback is started or paused, and processing corresponding to messages after message 910 is performed. . Note that whether to play or pause after moving the playback position changes according to the state when the jump button was last pressed (except when the message 902 to 916 is being operated), and whether it is being played back. If the playback position is moved, playback is performed. If the playback position is paused, the playback position is paused after the playback position is moved.

  When the forward jump button 206 is pressed many times and the backward jump button is pressed before the end of the jump operation, the forward jump count is reduced by the number of times the backward jump button is pressed. be able to. The same applies to the reverse case.

  As in the first embodiment, when the jump button is continuously pressed, the next jump operation can be performed immediately after the jump process is completed. In this operation, it is also possible to jump to a certain number of jump points instead of jumping to the next jump point. The fixed number of jumps can be set to the number displaying the jump point information in FIG. In the case of FIG. 7, the jump is made to jump to the next three jump points.

(4) When the search results are transferred to the jump processing unit 805 one by one using the message 907 A case where the search results are transferred to the jump processing unit 805 using the message 907 when one search result is obtained by the message 906 will be described.

  For the sake of simplicity, it is assumed that no search has been performed previously. That is, it is assumed that there is no jump point held by the jump processing unit 805.

  When the first search result is found by executing the search, a message 907 notifies the jump processing unit 805 of the result.

  Thereafter, the jump processing unit 805 generates a first jump point based on the message 908, and continues processing after the message 909. At this time, since the search result necessary for generating the jump point necessary for display on the screen of FIG. 7 has not been obtained, the jump point information display area 702 as shown in FIG. 7 is not displayed. However, when displaying the jump point information, only one jump point information display area 702 as shown in FIG. 7 is displayed. At the same time, the search unit 803 continues the search to obtain the next search result.

  When the search unit 803 finds the next search result, the search result is notified to the jump processing unit 805 by a message 908.

  When the jump processing unit receives this message, a jump point is generated by the message 908. Since the jump has already been performed, the processing according to the message 909 is not executed, and the processing after the message 910 is executed. By this processing, one new jump point information display area 702 in FIG. 7 is created and displayed on the screen.

  When a plurality of jump point information display areas 702 are displayed as shown in FIG. 7, the search by the search unit 803 is continued until the corresponding number (three in FIG. 7) is displayed.

  It is also possible to continue searching until all files are searched. In that case, the process after the message 910 is executed until the generation of the jump point information display area 702 is completed, but after that, only the generation of the jump point by the message 908 is performed.

(5) When the jump buttons 205 and 206 are pressed during the processing of the search unit 803 A case where the jump buttons 205 or 206 are pressed during the processing of the search unit 803 (processing of messages 904 to 906) will be described.

  When the user presses the jump button, messages 901 and 902 are first processed.

  When the search has been completed, that is, when the jump point has been generated, the search is not executed, and the processing after the message 909 is performed.

  If the search has not been completed, a message 903 is notified to the search unit 803. At this time, the search unit 803 stops the search process being executed and starts the search process from the position specified by the message 903. The jump processing unit 805 waits until a search result is generated, and generates a jump point when the result is obtained. Thereafter, processing after the message 909 is performed.

(6) Effects of the Second Embodiment By displaying the jump destination information on the display unit 808 in this way, the user knows the jump destination information before performing the jump operation. That's it. In addition to this, when there are many jump points and it is necessary to repeatedly press the jump button until the target jump point is reached, it can be known that there are a large number of unrelated jump points. Although the information to be displayed is increased, the operation is not different from that of the first embodiment, and the effect of jumping by using only the forward jump button 206 and the backward jump button 205 is maintained.

[Third Embodiment]
In the first embodiment and the second embodiment, all the search keys recorded in the search key database 102 are used for the search when executing the search. However, when there are a large number of recorded search keys, In addition to the possibility that a large number of jump points are generated, many search keys that do not want to use the search results as jump points are also used. In this embodiment, in order to solve this problem, files are grouped so that a search key used for search can be added / deleted for each group.

(1) Configuration of Video / Audio Data Processing Device FIG. 12 is a block diagram of the video / audio data processing device according to this embodiment.

  In addition to the second embodiment, there are a part relating to a setting operation for performing grouping and assigning a group ID to each group and a part relating to a search key for each group.

  The group ID is associated with each file, and the files associated with the same group ID belong to the same group. The association between the group ID and the file is stored in the group ID assignment storage unit 1211. The search key for each group is stored in the search key list storage unit 1212, and an arbitrary number of search keys can be assigned to each group ID. A collection of an arbitrary number of search keys associated with each group ID is referred to as a search key list. In summary, one search key list is assigned to each group ID, and an arbitrary number of search key numbers are recorded in each search key list.

(2) Method for setting group ID First, a method for setting a group ID in a file will be described.

  The group ID allocation control unit 1214 creates a new HDD when a new data is created in the video / audio data recording unit 1201, that is, when a video tape or DVD is inserted into the video / audio data processing device or a broadcast program or the like. Called when recorded in. At this time, the group ID assignment control unit 1214 reads the information of the newly created file from the video / audio data recording unit 1201, reads the information such as the title recorded in the file, and based on the read information, the file Assign a group ID to. If it belongs to a group that has already been created, the corresponding group ID may be assigned. If it does not match any existing group, a new group ID may be generated and assigned. In the present embodiment, the group ID is automatically assigned as described above. However, a separate UI may be provided so that the user can manually assign the group ID, or a combination of both may be provided. good.

  Although the case where the files are grouped when performing the jump processing across the files in the first embodiment has been described, the group described in the present embodiment can also be used as the group.

(3) Method for Assigning Search Key Next, a method for assigning the search key to the search key list of each group will be described.

  When setting the search key list, the user presses the key list button 1507 of the remote controller (FIG. 15) in a situation where any file belonging to the group to be set can be specified.

  Then, a search key list setting screen as shown in FIG. 16 is displayed on the display unit 1208. On the left side of FIG. 16, information on all search keys existing in the search key database is displayed. If the search key has only the name information, only the name is displayed as text 1604. If the image exists as information, the name is displayed as image 1605. If the moving image exists as information, the moving image is reproduced.

  On the right side of the screen, a representative screen generated from the vicinity of the jump point obtained from the result of searching the video / audio data with the search key displayed on the left side is displayed as an image 1606. Here, the video / audio data to be searched is the video / audio data specified when the key list button 1507 is pressed.

  It is also possible to display only the search key information without displaying the search result in order to reduce the processing amount.

  Although only three search keys are displayed in FIG. 16, if there are more search keys in the search key database 1202, the remaining search key information is displayed by scrolling the screen. Which search key information is displayed in the whole is represented by a scroll bar 1602 at the right end. A triangle 1603 displayed on the left side indicates a currently selected search key, which can be moved by up and down arrow keys 1508 and 1510 on the remote controller (FIG. 15).

  Although a triangle is used in FIG. 16 to indicate which search key is selected, any figure may be used, and the background color of the display line of the selected search key may be changed. Any other method can be used as long as the method is known to be selected. In the search key display area already registered in the search key list, the display of the row of the search key is changed so that the user can recognize it. In FIG. 16, an asterisk 1607 is displayed as an example.

  To register a search key in the search key list, select one of the search keys without the star 1607 and press the add / delete button 1509 on the remote control (FIG. 15), and the selected search key becomes the search key. It is registered in the list and an asterisk 1607 is displayed on the screen.

  On the other hand, when it is desired to delete a search key from the search key list, one of the search keys with the star 1607 is selected and the remote controller add / delete button 1509 is pressed to delete the search key from the search key list. Is done.

  The search key used when performing the jump process is set by the above operation.

(4) Operation when the jump button is pressed during playback The operation when the jump button is pressed during playback of video / audio data will be described with reference to FIG. There are many parts similar to the first and second embodiments.

  When the forward jump button 206 is pressed, the jump processing unit 1205 starts processing by a message 1901.

  The jump processing unit 1205 acquires reproduction information by using a message 1902.

  If not searched, a message 1903 is sent to the search unit 1203, and the search unit 1203 uses the reproduction information acquired by the jump processing unit 1205 to start a search.

  The search unit 1203 acquires the group ID associated with the file from the file name from the group ID assignment storage unit 1211 using the message 1904. Using the acquired group ID, a search key list is acquired from the search key list storage unit 1212 by a message 1905. Using the obtained search key list, the search key is acquired from the search key database 1202 by the message 1907, the video / audio data is acquired from the video / audio data recording unit 1201 by the message 1907, and the video / audio data is acquired by the message 1908. Perform a search.

  The jump processing unit 1205 that has received the search result generates a jump point.

  This is the operation when the search has not been completed.

  The other operations are the same as those in the first and second embodiments up to the message 1918. That is, in the first and second embodiments, all the search keys recorded in the search key database 1202 are used as the search keys used for the search. In the present embodiment, the video / audio data being reproduced is used. The difference is that the search key recorded in the search key list associated with the group ID of the group to which the group belongs is used.

  The message 1919 waits for a certain period of time, and then the screen display is turned off from the display unit 1208 by a message 1920 and a message 1921.

  Further, the second embodiment is different from the second embodiment in the operation while waiting for a certain time by the message 1919 of FIG. 19 while FIG. 7 is displayed. The operation while waiting will be described with reference to FIGS. 20 and 21. FIG.

  If the user presses the add / delete button 1509 on the remote control (FIG. 15) while the jump processing unit 1205 waits for a certain period of time, the jump processing unit 1205 jumps when the previous jump button is pressed in the message 2002. Get the search key number from the jump point.

  Next, the group ID of the file being reproduced is acquired from the group ID assignment storage unit 1211 by the message 2003. Using this search key number and group ID, the search key list storage unit 1212 deletes the specified search key from the search key list of the specified group ID by the message 2004.

  Finally, the jump processing unit 1205 notifies the jump processing UI display unit 1207 of the deletion by a message 2005, and the jump processing UI display unit 1207 displays the information of the jump point searched by the deleted search key. For example, as shown in FIG. 21, an X mark is added, and the screen is output to the display unit 1208.

  If the user presses the add / delete button 1509 again before pressing the jump button next time or before the display of the jump processing UI display unit 1207 disappears, the deletion operation from 2002 to 2007 is performed because it has already been deleted. It is possible to carry out either the method of not having the deletion or the method of canceling the deletion and adding the same search key to the search key list again.

  If a forward jump or backward jump occurs while waiting by the message 1919, the process stops waiting and returns to step 1902 of FIG. 19 to perform the jump process.

(5) Effects of Third Embodiment As described above, according to the present embodiment, even if a large number of search keys are registered in the search key database 1202, the user uses a search for jumping to each video / audio data. The key can be specified.

  Also, it is possible to perform a jump operation using the search key associated with the group ID only by assigning an appropriate group ID to data newly added to the video / audio data recording unit 1201. Become.

  For example, in the case of recording each time a specific news program is broadcasted by assigning the sound effect flowing for each topic in the news to the search key list as a search key, the user can add a bookmark or the like. The playback position can be moved for each topic without manually setting, and the user can quickly view only the topic he / she wants to see.

(6) Modification Example In this embodiment, files are divided into groups, and a search key list is provided for each group. However, a search key list can be provided for each file without grouping. .

  In this case, it is necessary to set a search key in the search key list every time a file is added, but a portion for grouping is not necessary. Further, since it is possible to use different search keys for each file, even if a large number of search keys are registered in the search key database 1202, the user can select only the necessary search keys.

[Fourth Embodiment]
The first to third embodiments can be applied to video / audio data or video-only data. However, the representative screen cannot be displayed when only audio data is used, and the display unit 108 may not be provided when only audio data is reproduced. In the present embodiment, the difference from the first embodiment will be described in the case where only audio data is handled.

  A block diagram of the present embodiment is shown in FIG. The same as FIG. 1 except that the portion related to the screen display is eliminated.

  The operation when the forward jump button 206 is pressed is almost the same as that described with reference to FIG. 3 in the first embodiment. The difference is that the screen output operations of the message 309 and the message 310 are not performed.

  When a screen is attached to the voice data processing apparatus, it is possible to display a jumping message or the name of the matched search key.

  Even in the case of only audio data according to the present embodiment, if a search key is registered in the search key database 1802, jump processing can be performed, and audio data of a file recorded for a long time can be easily reproduced.

[Fifth Embodiment]
In the first to fourth embodiments, the jump point is generated using only the result obtained from the search. However, if the user has set a bookmark in the video / audio data, this bookmark is used. Can also be treated as a jump point.

  A block diagram in which this function is added to the first embodiment is shown in FIG. In addition, it can add similarly to 2nd Embodiment to 4th Embodiment.

  FIG. 23 shows a sequence diagram in which processing related to bookmarks is added to FIG. Most of the processing is the same as that in FIG. 3, but a process for the jump processing unit 2205 to acquire bookmark position information from the bookmark storage unit 2210 by a message 2308 after the search is added. The position of the bookmark acquired by this processing is treated as a jump point.

  When the playback position is moved by the message 2309, it is moved to the jump point closest to the current position regardless of whether it is a jump point generated from a bookmark or a jump point generated from a search result.

  When the jump point information is also displayed as in the second embodiment, it can be displayed that the jump point is generated from the bookmark as shown in FIG. 17 (in the case of FIG. 17, the center jump point information is displayed). "Bookmark" appears in the area). The representative screen may be generated in the same manner as the generation of the jump point representative screen generated from the search result.

  Note that the method for generating the representative screen may be different depending on whether the jump point is a bookmark or the search result.

  According to this embodiment, the user can perform a jump operation only by using the forward jump button 206 or the backward jump button 205 regardless of the jump point generated from the jump point bookmark generated by the search.

[Sixth Embodiment]
In the first to fifth embodiments, search processing is executed for already recorded video / audio data. However, it is also possible to execute search processing for video / audio data being recorded. is there. Although this embodiment will be described based on the first embodiment, the functions described here can be implemented in other embodiments as well.

(1) Configuration of Video / Audio Data Processing Device FIG. 26 is a block diagram. The difference from FIG. 1 is that a receiving unit 2610 is added.

  The receiving unit 2610 receives various data. For example, there are terrestrial broadcasting, satellite broadcasting, Internet streaming broadcasting, data sent from a surveillance camera, and the like. The received video / audio data is sent to the video / audio data recording unit 2601 and recorded. Although the receiving unit 2610 is used here, this may be a video camera or a microphone.

(2) Pressing the jump button While recording the received video / audio data, the user can play it back and watch it. Even if the user presses the forward jump button 206 while viewing in real time, that is, while viewing the latest received video / audio data, there is no data to search. Also does not happen.

  On the other hand, when the backward jump button is pressed, jump processing is executed on the video / audio data recorded so far in the same manner as in the first embodiment, and playback is performed from that position after the jump. The video / audio data being received is continuously recorded. If data past from the latest received video / audio data is being reproduced, a forward jump can be performed by pressing the forward jump button 206.

  In the first embodiment, when a search is performed by pressing the forward jump button 206 and there is no portion that matches the search key, a message indicating that the jump could not be performed is displayed. However, in this embodiment, the operation at this time is different from that of the first embodiment. If the forward jump button 206 is pressed while data past from the latest received video / audio data is being played back, search processing is performed. At this time, if there is no portion that matches the search key, the playback position is moved to the position of the latest received video / audio data, and switching to real-time viewing is performed.

(3) Effects of Sixth Embodiment According to the present embodiment, the next operation can be performed with only two buttons, the forward jump button 206 and the backward jump button 205.

  The first is when the user misses a place that he / she wanted to watch while viewing in real time, and when the user can search for the part he / she wants to watch using the search key, he / she just missed it by pressing the back jump button. It becomes possible to review.

  Second, it is possible to return to real-time viewing by pressing the forward jump button after reviewing the missed location.

[Seventh Embodiment]
In the first to sixth embodiments, data encoded by MPEG or the like is completely decoded, and then the data is passed to the search unit. In this embodiment, only data necessary for the search is decoded. To simplify the description, the description will be made based on the first embodiment, but the present invention can be applied to other embodiments.

(1) Configuration of Video / Audio Data Processing Device FIG. 27 shows a block diagram of this embodiment.

  The reproduction decoder 2710 performs decoding necessary for reproduction to the end. This is the same as in other embodiments. However, the search decoder 2711 performs decoding only to the stage necessary for the search. In the present embodiment, video / audio data encoded by MPEG-1 will be described as an example. Furthermore, it is assumed that the audio data is encoded in MPEG-1 audio layer III.

  The search unit 2703 uses only audio data, and uses frequency domain data.

(2) Processing Related to Search Decoder Since the operation other than the operation of the search decoder 2711 is the same as that of the first embodiment, only the processing related to the search decoder will be described.

  When the user presses the jump button and the search is executed, the search unit 2703 acquires the video / audio data from the video / audio data recording unit 2701 through the search decoder 2711. At this time, the search decoder 2711 performs the following operation.

  1. Video / audio data encoded by MPEG-1 is read from the video / audio data recording unit 2701.

  2. In MPEG-1, since video data and audio data are multiplexed and recorded as one bit stream, only the bit stream in which audio is recorded is separated therefrom.

  3. Using the audio bitstream, it performs Huffman decoding and inverse quantization. At this point, a frequency domain signal is obtained.

  4). In this example, since the search unit 2703 uses frequency domain data, the frequency domain data of the audio data is transmitted. Note that the playback decoder 2710 performs normal decoding processing.

  By performing the processing as described above, the search unit 2703 depends on a standard (for example, MPEG-1) used for encoding video / audio data. Instead, the encoded video / audio data is encoded. It is possible to reduce the amount of calculation required when searching for. In the example described in the present embodiment, the video data decoding process is unnecessary, and the audio data decoding process is also only halfway.
