  [Configuration and basic operation]

  FIG. 1 is a diagram showing a configuration of a content management apparatus according to an embodiment of the present invention.

  Referring to FIG. 1, a content management apparatus 101 includes a reception unit 102, an analysis unit 103, a content recording / playback unit 104, a content information management unit 105 (content sort unit), a display control unit 106, and a user interface. 107.

  The content management apparatus 101 sorts and displays a plurality of managed recording contents. For example, a plurality of recorded contents recorded in an HDD (Hard Disk Drive) 108 are sorted and displayed.

  More specifically, the content management apparatus 101 is, for example, an STB (Set Top Box), receives a stream from the station side apparatus, decodes video and audio from the stream, and reproduces the content on the display 109. Furthermore, the content management apparatus 101 records the received content on an HDD (Hard Disk Drive) 108 or plays back the recorded content recorded on the HDD 108 on the display 109.

  The station-side device is, for example, a device installed in a digital broadcasting broadcast station or a server corresponding to IPTV (Internet Protocol Television). Note that the content management apparatus 101 may be configured to include the display 109.

  The receiving unit 102 extracts PSI (Program Specific Information), video data and audio data from the received stream and outputs them to the content recording / playback unit 104, and also extracts SI (Service Information) and outputs it to the analysis unit 103 To do.

  The SI includes a series descriptor defined by ARIB (Association of Radio Industries and Businesses) and an EPG (Electronic Program Guide).

  The series descriptor is series_id (series identification) for uniquely identifying a series of series such as drama or animation, episode_number (number of episodes) indicating the number of episodes in the series of the program indicated by the series identification, and series identification is effective. It consists of expire_date (expiration date) indicating the date of expiration and series_name_char (series name) which is a character string indicating the program name indicated by the series identification.

  The EPG includes program information for 8 days in total and basic information that is simple introduction, detailed information such as contents and performers, and genre information.

  The analysis unit 103 analyzes the SI received from the reception unit 102 and outputs, for example, program information such as a program title, broadcast date and time, and a genre to which the program belongs to the content information management unit 105.

  If the received program has a series descriptor, the analysis unit 103 also outputs the series identification, the number of stories, the expiration date, and the series name to the content information management unit 105.

  The content recording / playback unit 104 refers to the PSI received from the receiving unit 102, decodes video data and audio data necessary for playback of the received content, and outputs them to the display control unit 106.

  The display control unit 106 plays back the video data and audio data of the received content received from the content recording / playback unit 104 on the display 109.

  When the content management apparatus 101 is connected to the HDD 108 installed outside the content management apparatus 101, the content management apparatus 101 can record the received content on the HDD 108.

  Also, the content management apparatus 101 can play back the content held by the HDD 108 on the display 109 when connected to the HDD 108 installed outside the content management apparatus 101.

[HDD synchronization]
When the content recording / playback unit 104 recognizes that the user has connected the HDD 108 to the content management apparatus 101, the content recording / playback unit 104 acquires the HDD identification ID of the HDD 108 and then notifies the content information management unit 105 of the HDD identification ID.

  The HDD identification ID is an ID for identifying the HDD 108. For example, an individual identification number of the HDD 108 may be used.

  Upon receiving the HDD identification ID of the HDD 108 and the notification that the HDD 108 is connected from the content recording / playback unit 104, the content information management unit 105 receives the new HDD identification ID of the HDD 108 notified from the content recording / playback unit 104. It is determined whether the ID is an HDD identification ID or an HDD identification ID having a connection history.

  In the case of a new HDD identification ID, the content information management unit 105 creates an array of management tables in order to manage content information recorded in the HDD 108.

  In the case of the HDD identification ID having a connection history, the content information management unit 105 displays the management table array corresponding to the connected HDD 108 based on the HDD identification ID of the HDD 108 notified from the content recording / playback unit 104. call.

  That is, the content information management unit 105 has a management table array for each HDD identification ID of the HDD 108.

  The members of the management table are, for example, content ID, program title, recording date and time, genre to which the program belongs, viewing flag, series identification, number of stories, expiration date, and series name.

  The content information management unit 105 uses one or more members of the management table as a sort key when sorting a plurality of recorded contents. Further, the display control unit 106 searches for a plurality of recorded contents by using one or more members of the management table as search keys, determines the recorded contents to be selected and displayed, and displays the members on the display 109 as recorded contents. Used for items when displaying a list.

  The content ID is a file name used when recording the content on the HDD 108, for example.

  In the case of the HDD 108 having a connection history, the content information management unit 105 confirms whether the content corresponding to the content ID that is a member of each element of the array of the management table is recorded in the HDD 108.

  More specifically, the content information management unit 105 provides the content recording / playback unit 104 with a content ID recorded in each element of the array of the management table and a corresponding content existence confirmation command.

  Upon receiving the content ID and the corresponding content existence confirmation command from the content information management unit 105, the content recording / playback unit 104 checks whether the corresponding content is recorded in the HDD 108 based on the content ID.

  The content recording / playback unit 104 notifies the content information management unit 105 of true (True) if the content corresponding to the HDD 108 exists, and false (False) if the content does not exist.

  When notified from the content recording / playback unit 104 that the content information management unit 105 is false, the content information management unit 105 deletes an element of the corresponding management table array. When true is notified, nothing is done. If the processing is completed for all the elements of the management table array, the synchronization between the information related to the recorded content managed by the content information management unit 105 and the content held by the HDD 108 is completed.

  In response to the synchronization command from the display control unit 106, the content information management unit 105 notifies True if the synchronization operation is completed successfully, and notifies False if the synchronization operation is abnormal.

  When the display control unit 106 receives a true return value in response to the synchronization command to the content information management unit 105, the content management apparatus 101 records the received content on the HDD 108 and stores it on the HDD 108. Preparation for playback of the recorded content on the display 110 is completed.

  If the display control unit 106 receives a false return value in response to the synchronization command to the content information management unit 105, the display control unit 106 may display a message indicating the abnormality on the display 109.

  The user interface 107 includes, for example, a button switch. When the user operates the button switch, the user inputs an operation that the user requests the content management apparatus 101 to the content management apparatus 101.

  The user interface 107 may be arranged in the casing of the content management apparatus 101, or may be a wireless remote control using infrared or a cable-type remote controller capable of communicating with the content management apparatus 101.

[Recording]
When the user presses a “record” button on the user interface 107, the content management apparatus 101 records the currently received content on the HDD 108.

  More specifically, when the user presses a “record” button in the user interface 107, the user interface 107 transmits a recording command to the display control unit 106. Subsequently, the display control unit 106 manages a recording command as content information management. Part 105.

  The content information management unit 105 that has received a recording command from the display control unit 106 adds one new element to the arrangement of the management table, and the program title, broadcast date / time, and program of the content to be recorded received from the analysis unit 103 are displayed. In addition to the genre information and the viewed flag, if the series descriptor is available, the series identification, the number of stories, the expiration date, and the series name are written in the corresponding member of the array element newly added to the management table. Here, the content information management unit 105 writes the viewed flag as false by default.

  Subsequently, the content information management unit 105 determines the content ID and writes it in the corresponding member of the array element newly added to the management table. The content information management unit 105 may generate a content ID based on, for example, a program title or broadcast date / time.

  Next, the content information management unit 105 outputs the recording command and content ID of the currently received content to the content recording / playback unit 104.

  Upon receiving the recording command and the content ID from the content information management unit 105, the content recording / playback unit 104 secures a recording area for recording the received content in the HDD 108, and sets the address of the secured recording area and the content ID. The content recorded on the HDD 108 can be referred to by the content ID.

  After confirming that the recording area can be secured in the HDD 108, the content recording / playback unit 104 refers to the PSI received from the receiving unit 102, encodes necessary video data and audio data, and stores the recording area in the HDD 108. record.

  When the user presses a “recording stop” button on the user interface 107, the content management apparatus 101 stops the recording of the currently received content on the HDD 108.

  More specifically, when the user presses a “recording stop” button in the user interface 107, the user interface 107 transmits a recording stop command to the display control unit 106, and then the display control unit 106 issues a recording stop command. This is given to the content information management unit 105.

  Upon receiving the recording stop command from the display control unit 106, the content information management unit 105 writes the end time at the recording date and time that is a member of the element newly added at the start of recording of the content in the arrangement of the management table. Subsequently, the content information management unit 105 outputs a content recording stop command and the content ID of the currently received content to the content recording / playback unit 104.

  Upon receiving the recording stop command and the content ID from the content information management unit 105, the content recording / playback unit 104 stops the recording of the received content on the HDD 108, and at the end of the recording area in the HDD 108 secured at the start of recording. An end of file indicating the end of the file is added.

  A series of operations from the start of recording to the stop of recording may be made so that the content management apparatus 101 can record content received at a predetermined time by a timer not shown in the figure.

[Regeneration]
The user can play back the recorded content recorded in the HDD 108 on the display 109, but the user needs to select in advance which recorded content is to be played back.

  For example, when the user presses a “recording list display” button on the user interface 107, the content management apparatus 101 displays a recorded content list describing recorded content recorded on the HDD 108 on the display 109. The user can select the recorded content to be reproduced by referring to the recorded content list.

  More specifically, when the user presses a “recording list display” button, the user interface 107 transmits a recording list display command to the display control unit 106.

  Upon receiving the recording list display command from the user interface 107, the display control unit 106 displays the recorded content list on the display 109.

  FIG. 2 is a first diagram for explaining a display example of a recorded content list in the content management apparatus according to the embodiment of the present invention.

  FIG. 3 is a second diagram for explaining a display example of the recorded content list in the content management apparatus according to the embodiment of the present invention.

  2 and 3 show the content management apparatus according to the embodiment of the present invention, in which the display control unit 106 performs a selection display determination operation for determining a recorded content to be selected and displayed among a plurality of sorted recorded contents. In addition, when scrolling is performed on the screen on which the recorded content list is displayed, it is assumed that the shortened circulation operation for circulating the recorded content displayed on the screen in a part of the plurality of recorded content is not performed. It is a figure of the video recording content list | wrist displayed on the display 109 in the case of having performed. The recorded content list is sorted in order of recorded date and time, the vertical axis represents the time axis, and the recorded content recorded in the past is shown in the lower part of the page.

  For example, in FIG. 2, the content management apparatus 101 holds 14 recorded contents, but since the number of recorded contents that can be displayed at one time is 9, the recorded content list covers two pages. The number of recorded contents that can be displayed at one time by the content management apparatus 101 may be changed by the user according to preference.

  FIG. 2 shows the first page 201 of the recorded content list that is displayed first after the user presses the “display recording list” button on the user interface 107. FIG. 3 shows the second page 301 of the recorded content list that is not displayed simultaneously with the first page of the recorded content list.

  After the user presses the “recording list display” button on the user interface 107, the display control unit 106 displays the first page 201 of the recorded content list on the display 109, and further displays the first list in the recorded content list. The element 202a is determined as the recorded content to be selectively displayed.

  Here, the selection display is made for the recorded content in a selectable state in the recorded content list. That is, the recorded content selected and displayed has a focus. In FIG. 2, the element 202a of the first list has the focus, and the element of the list having the focus is displayed in white in the recorded content list.

  List elements in the recorded content list have program title 203, recording date and time 204, and viewed flag 205 as items.

  More specifically, for example, in FIG. 2, the display control unit 106 collects information necessary to draw the first page 201 of the recorded content list having focus on the element 202a of the first list. An output command for the number of elements in the management table array is given to the management unit 105. Here, the number of elements in the array of the management table is the same as the number of recorded contents.

  In response to the output command from the display control unit 106, the content information management unit 105 outputs 14 which is the number of elements in the management table array to the display control unit 106.

  The display control unit 106 that has received 14 which is the number of elements in the management table array from the content information management unit 105, the recorded content list is composed of 9 contents per page. And 14 is stored as the number of recorded contents and 2 as the total number of pages in the recorded contents list. Further, the element number of the list having the current focus, that is, 1 indicating the current list index is also stored.

  Next, the display control unit 106 gives the content information management unit 105 an instruction to output a program title, a recording date and time, and a viewed flag that are members of the first to ninth elements of the management table array.

  Upon receiving the output command from the display control unit 106, the content information management unit 105 outputs the program title, the recording date and time, and the viewed flag that are members of the first to ninth elements of the management table array to the display control unit 106. To do.

  The display control unit 106 that has received the program title, the recording date and time, and the viewed flag as members of the first to ninth elements of the management table array from the content information management unit 105 performs the following drawing on the display 109, Draw the first page of the recorded content list.

  That is, the display control unit 106 displays 1 as the number of currently displayed pages 206, 2 as the total number of pages 207, 14 as the number of recorded contents 208, the specified sort condition 209, and content information management. The program title 203 which is a member from the first element 202a to the ninth element 202i of the management table array received from the section 105, the recording date and time 204, and the viewed flag 205 are displayed.

  Here, the display control unit 106 displays only the elements 202 in the first list with focus in white, and displays the elements other than the elements in the first list in black.

  The user can move the focus by pressing a cursor control button on the user interface 107. Further, the user scrolls on the screen on which the recorded content list is displayed by moving the focus.

  The movement of the focus in the recorded content list over two pages follows the method of a bidirectional circular list over two pages. The bidirectional circular list is a list in which the first element and the last list element in the list are linked to each other.

  4 and 5 show the content management apparatus according to the embodiment of the present invention, in which when the user presses the cursor control button on the user interface 107, the display control unit moves the focus in the recorded content list and performs recording. It is the flowchart which defined the operation | movement procedure at the time of performing the display process of a content list.

  The content management apparatus 101 reads and executes each step of each flowchart shown below from a memory (not shown). This program can be installed externally. The installed program is distributed in a state stored in a recording medium, for example.

  With reference to FIG. 4 and FIG. 5, the method of the bidirectional | two-way circular list over 2 pages is demonstrated in detail.

  First, referring to FIG. 4, first, the user interface 107 monitors the pressing of the “up arrow” button for cursor control on the user interface 107 by the user (step S <b> 41).

  Next, when the user interface 107 detects that the user has pressed the “up arrow” button for cursor control on the user interface 107, the user interface 107 transmits a focus up movement command to the display control unit 106 (YES in step S41).

  Upon receiving the focus up movement command from the user interface 107, the display control unit 106 checks the current list index, and changes the display of the list element corresponding to the current list index displayed on the display 109 from white to black. Change (step S42).

  Subsequently, the display control unit 106 stores 1 after subtracting 1 from the current list index (step S43). For example, when the number of recorded contents is 14, if the current list index is 3, the display control unit 106 changes the current list index to 2 and stores it. Further, when the current list index is 1, the display control unit 106 changes the current list index to 14 and stores it. That is, the recorded content list is a bidirectional circulation list.

  Next, when the display control unit 106 confirms that the recorded content list page currently displayed on the display 109 includes a list element corresponding to the current list index (YES in step S44), the display 109 The display of the list element corresponding to the current list index displayed in is changed from black to white (step S48).

  On the other hand, when the display control unit 106 confirms that the list element corresponding to the current list index is not included in the currently displayed page of the recorded content list on the display 109 (NO in step S44), the display control unit 106 106 acquires information necessary for displaying the page one page before the page of the recorded content list currently displayed on the display 109 from the content information management unit 105 (step S45).

  More specifically, the display control unit 106 outputs an output command of the program title, the recording date and time, and the viewed flag, which are members of the elements of the management table array necessary for displaying the corresponding page in the recorded content list. To give.

  Here, the range of the elements of the necessary management table array can be easily calculated from the number of recorded contents, the number of elements of the list displayed per page of the recorded contents list, and the page number to be displayed.

  For example, if the page of the recorded content list currently displayed on the display 109 is the second page, the display control unit 106 is an array element of the management table necessary for displaying the first page, that is, 1 of the array of the management table. If the content information management unit 105 is given a command to output the program title, the recording date and time, and the viewed flag that are members of the ninth to ninth elements, and the currently displayed recorded content list page is the first page, The display control unit 106 outputs an output command of the program title, the recording date and time, and the viewed flag, which are members of the tenth to fourteenth elements of the management table array necessary for displaying the second page. Give to 105.

  The content information management unit 106 that has received a command to output the program title, the recording date and time, and the viewed flag, which are members of the elements of the management table array necessary for displaying the corresponding page in the recorded content list, from the display control unit 106 The read value is output to the display control unit 106 with reference to the table array.

  Next, the display control unit 106 deletes the page of the recorded content list currently displayed on the display 109 (step S46).

  Subsequently, based on the information received from the content information management unit 105, the display control unit 106 draws a page one page before the deleted page in the recorded content list (step S47), and subsequently displays it on the display 109. The display of the list element corresponding to the current list index is changed from black to white (step S48), and the focus upward movement process is completed.

  Next, referring to FIG. 5, first, the user interface 107 monitors the pressing of the “down arrow” button for cursor control on the user interface 107 by the user (step S <b> 51).

  Next, when the user interface 107 detects that the user has pressed the “down arrow” button for cursor control on the user interface 107, the user interface 107 transmits a focus down movement command to the display control unit 106 (YES in step S51).

  The display control unit 106 that has received the focus down movement command from the user interface 107 checks the current list index, and changes the display of the list element corresponding to the current list index displayed on the display 109 from white to black. Change (step S52).

  Subsequently, the display control unit 106 adds 1 to the current list index and stores it (step S53). For example, when the number of recorded contents is 14, if the current list index is 3, the display control unit 106 changes the current list index to 4 and stores it. Further, when the current list index is 14, the display control unit 106 changes the current list index to 1 and stores it. That is, the recorded content list is a bidirectional circulation list.

  Next, when the display control unit 106 confirms that the list element corresponding to the current list index is included in the currently displayed page of the recorded content list on the display 109 (YES in step S54), the display 109 The display of the element of the list corresponding to the current list index displayed in is changed from black to white (step S58).

  On the other hand, when the display control unit 106 confirms that the list element corresponding to the current list index is not included in the currently displayed page of the recorded content list on the display 109 (NO in step S54), the display control unit 106 106 acquires information necessary for displaying a page one page after the page of the recorded content list currently displayed on the display 109 from the content information management unit 105 (step S55).

  More specifically, the display control unit 106 outputs an output command of the program title, the recording date and time, and the viewed flag, which are members of the elements of the management table array necessary for displaying the corresponding page in the recorded content list. To give.

  Here, the range of elements of the necessary management table array can be easily calculated from the number of recorded contents, the number of elements of the list displayed per page of the recorded contents list, and the page number to be displayed.

  For example, if the page of the recorded content list currently displayed on the display 109 is the second page, the display control unit 106 is an array element of the management table necessary for displaying the first page, that is, 1 of the array of the management table. If the content information management unit 105 is given a command to output the program title, the recording date and time, and the viewed flag that are members of the ninth to ninth elements, and the currently displayed recorded content list page is the first page, The display control unit 106 outputs an output command of the program title, the recording date and time, and the viewed flag, which are members of the tenth to fourteenth elements of the management table array necessary for displaying the second page. Give to 105.

  The content information management unit 106 that has received a command to output the program title, the recording date and time, and the viewed flag, which are members of the elements of the management table array necessary for displaying the corresponding page in the recorded content list, from the display control unit 106 The read value is output to the display control unit 106 with reference to the table array.

  Next, the display control unit 106 deletes the page of the recorded content list currently displayed on the display 109 (step S56).

  Subsequently, based on the information received from the content information management unit 105, the display control unit 106 draws a page one page after the erased page in the recorded content list (step S57), and then continues to step S58. Execute the focus down movement process.

  With reference to FIG. 2 and FIG. 3 again, a description will be given of the process until the user selects the recorded content to be reproduced from the recorded content list, reproduces it, and stops the reproduction.

  For example, if the user wants to play back the recorded content 302c with the program name “criminal drama”, which is the 12th recorded content in the recorded content list, the user presses the “down arrow” button for cursor control 11 times. , The focus can be moved to the element of the list corresponding to the current list index of 12.

  The user can also move the focus to an element of the list corresponding to the current list index 12 by pressing the “up arrow” button three times.

  When the user confirms that the recorded content to be reproduced matches the focus on the display 109 and presses the “play” button on the user interface 107, the content management apparatus 101 displays the recorded content 302c with the program name “criminal drama”. Play at 109.

  More specifically, when the user presses a “play” button on the user interface 107, the user interface 107 transmits a play command to the display control unit 106.

  Upon receiving the playback command from the user interface 107, the display control unit 106 gives the playback command and 12 which is the current list index to the content information management unit 105. Subsequently, the display control unit 106 deletes the recorded content list from the display 109.

  The content information management unit 105 that has received the playback command and the current list index of 12 from the display control unit 106 reads the content ID that is a member of the twelfth element of the array of the management table and plays back to the content recording / playback unit Instruction and content ID are given.

  The content recording / playback unit 104 that has received the playback command and content ID from the content information management unit 105 reads the corresponding recorded content from the HDD 108 based on the content ID, decodes video data and audio data necessary for playback, and performs display control. To the unit 106.

  The control display unit 106 plays back the video data and audio data of the recorded content received from the content recording / playback unit 104 on the display 109.

  For example, when the user presses a “playback stop” button on the user interface 107, the playback of the currently played content can be stopped. After the reproduction is stopped by the user, the content management apparatus 101 displays a recorded content list on the display 109. At this time, the recorded content 302c with the program name “criminal drama” has the focus.

  More specifically, when the user presses a “playback stop” button, the user interface 107 transmits a playback stop command to the display control unit 106, and the display control unit 106 that receives the playback stop command sends a playback stop command to the content information. This is given to the management unit 105.

  Upon receiving the playback stop command from the display control unit 106, the content information management unit 105 reads the content ID that is a member of the twelfth element that is the current list index in the management table array, and then the content information management unit 105 The content recording / playback unit 104 outputs a playback stop command for the currently played content and the content ID.

  The content recording / playback unit 104 that has received the playback stop command and the content ID from the content information management unit 105 stops the playback processing of the recorded content referenced by the content ID, and then the content recording / playback unit 104 performs display control. The playback stop is notified to the unit 106.

  The display control unit 106 that has received the reproduction stop from the content recording / playback unit 104 displays the second page of the recorded content list including the element 302c of the twelfth list, and the tenth to fourteenth arrangements in the management table array are necessary. The content information management unit 105 is provided with an output command of the program title, the recording date and time, and the viewed flag that are members of the first element.

  Upon receiving from the display control unit 106 an output command for the program title, the recording date and time, and the viewed flag that are members of the tenth to fourteenth elements of the management table array, the content information management unit 106 changes the management table array. The read value is referred to and output to the display control unit 106.

  Next, the display control unit 106 draws the second page in the recorded content list based on the information received from the content information management unit 105, and sets the focus to the element 302c of the 12th list.

  Alternatively, for example, when the recorded content being played back by the display control unit 106 is played to the end, the content management apparatus 101 ends the playback of the recorded content and displays the recorded content list on the display 109. At this time, the recorded content 302c with the program name “criminal drama” has the focus, and the viewed flag of the corresponding recorded content is changed from “not viewed” to “viewed”.

  More specifically, when the content recording / playback unit 104 detects an end-of-file indicating the end of the content file read from the HDD 108, the content recording / playback unit 104 sends the video data and audio data necessary for playback to the display control unit 106. After the transmission is completed, the end of file is output to the display control unit 106.

  Upon receiving the end-of-file from the content recording / playback unit 104, the display control unit 106 outputs 12 that is the current list index to the content information management unit 105 together with the notification of the completion of playback.

  The content information management unit 105 that has received the playback completion and the current list index of 12 from the display control unit 106 changes the viewed flag, which is a member of the 12th element of the management table array, from false (true) to true (true). Then, a notification of rewriting completion is output to the display control unit 106.

  Receiving notification of rewriting completion from the content information management unit 105, the display control unit 106 is required to display the second page of the recorded content list including the element 302c of the twelfth list. To the content information management unit 105 are output commands for program titles, recording dates and times, and viewing / listening flags, which are members of the first to fourteenth elements.

  Upon receiving from the display control unit 106 an output command for the program title, the recording date and time, and the viewed flag that are members of the tenth to fourteenth elements of the management table array, the content information management unit 106 changes the management table array. The read value is referred to and output to the display control unit 106.

  Next, the display control unit 106 draws the second page in the recorded content list based on the information received from the content information management unit 105, and sets the focus to the element 302c of the 12th list.

  6 and 7 show that when the display control unit 106 displays on the display 109 the recorded content list sorted in order of the recording date and time when it is assumed that the selection display determination operation and the shortened circulation operation are not performed. It is the 1st and 2nd figure for demonstrating the problem of.

  6 and 7, the recorded content list is sorted in order of recording date and time, the vertical axis represents the time axis, and the recorded content recorded in the past is shown in the lower part of the page. The total number of recorded contents is 80, and the recorded content list covers 9 pages.

  Consider a case where a large amount of content is recorded after the content management apparatus 101 has recorded the recorded content requested by the user. That is, the recorded content requested by the user is the content of the program name “Mello Drama Episode 4” recorded at 21:00 on May 25, 2011 (Wednesday), and the content management apparatus 101 recorded the corresponding content. Assume that 38 contents are recorded later.

  FIG. 6 is a diagram showing the first page of the recorded content list that is first displayed by the content management apparatus 101 after the user presses the “recorded list display” button in the user interface 107. Here, the element 602a of the first list has the focus.

  FIG. 7 is the fifth page of the recorded content list, and the recorded content of the program title “Merodrama Episode 4” recorded at 21:00 on May 25, 2011 (Wednesday) requested by the user. Have been described.

  The recorded content having the program title “Mello Drama Episode 4” requested by the user is not displayed on the first page of the recorded content list shown in FIG. This is because the content management apparatus 101 recorded 38 contents after the date and time when the recorded content requested by the user was recorded, so that the rank of the recorded content requested by the user in the recorded content list sorted in order of date and time reaches 39th. This is because it falls.

  However, when the content management apparatus 101 displays the recorded content list for the first time, the user does not know that the rank of the recorded content requested by the user has dropped to 39th.

  Therefore, in order to play back the recorded content requested by the user, the user presses the “down arrow” button for cursor control in the user interface 107 to lower the focus one by one in the forward direction, and the recording shown in FIG. The user is forced to move the focus while reading the program titles of as many as 39 recorded contents until the focus is matched with the recorded content requested by the user on the fifth page of the content list.

  Further, in order to reproduce the recorded content requested by the user, the user reversely presses the “up arrow” button for cursor control in the user interface 107 to raise the focus one by one in the reverse direction, as shown in FIG. The recorded content requested by the user can be focused.

  However, in this case as well, the user is forced to move the focus while reading the program titles of as many as 42 recorded contents until the focus matches the recorded contents requested by the user shown in FIG.

  As described above, it is very troublesome for the user to search for the recorded content desired by the user while moving the focus forward or backward.

  For example, the user interface 107 may be provided with a button that allows the user to advance one page in the recorded content list or back one page. However, even when this button is used, each time the user advances the page of the recorded content list by one page or returns by one page, the user reads the list elements on the displayed page one by one, and the user requests You must check if it matches the recorded content.

  FIGS. 8 and 9 show the display 109 displaying the recorded content list sorted in the order of program titles on the assumption that the display control unit 106 does not perform the selection display determination operation and the shortened circulation operation described above. It is the 1st and 2nd figure for demonstrating the problem of.

  The storage capacity of the HDD 108 for recording digitized content tends to continue to increase in the future. For example, the HDD 108 having a storage capacity of 2 terabytes is about 250 high-definition (HD) one-hour programs, which are standard. About 400 programs can be recorded for one hour of image quality (SD).

  For example, in FIG. 8 and FIG. 9, the recorded content list is sorted in the order of the program titles of the recorded recorded content, the vertical axis represents the character code axis, and the recorded content has a larger character code at the bottom of the page. Yes. The total number of recorded contents is 130, and the recorded content list covers 15 pages.

  FIG. 8 is a diagram showing the first page of the recorded content list that is first displayed by the content management apparatus 101 after the user presses the “recorded list display” button in the user interface 107. Here, the element 802a of the first list has the focus.

  FIG. 9 is the eighth page of the recorded content list, and the recorded content with the program name “Night Drama Episode 5” recorded at 23:45 on May 31, 2011 (Tuesday) requested by the user. Is described.

  For example, when the user knows that the program title of the recorded content that the user wants is “Night Drama Episode 5”, the user will read “Night Drama Episode 5” on which page of the recorded content list. It is possible to predict whether or not recorded content having a program title will be displayed.

  However, even when the user knows the program title of the recorded content that the user wants, if the number of recorded content is 130, the user moves the focus from the recorded content having the program title starting with “A”. It may take a long time to reach a recorded content with a program title starting with 'N'.

  FIG. 10 is a diagram for explaining another problem that occurs when the search result of the recorded content list is displayed on the display 109.

  In FIG. 10, the content management apparatus 101 searches for the program title of the recorded content recorded in the HDD 108 using the search word 1006 “night drama”, and the character string “night drama” is part of the program title. This is the result of outputting the recorded content including the recorded content search list 1001.

  For example, when the user knows that the program title of the recorded content that the user wants is “Night Drama Episode 5”, the user selects the recorded content that includes the phrase “Night Drama” as part of the program title. Searchable.

  When the user knows the program title of the recorded content requested by the user, the user can easily find the recorded content requested by the user by searching, but information on the recorded content that does not match the search condition is lost.

  For example, the recorded content having the program name “Nice Swing Episode 3” shown in FIG. 9 is the same recorded content when the “Night Drama Episode 5” requested by the user is recorded. If the user forgets that the recorded content with the program name “Nice Swing Episode 3” has been recorded, the user simply searches for the recorded content including “Night Drama” in the program title. It is difficult to find the content that the user has forgotten.

  Therefore, the content management apparatus according to the embodiment of the present invention solves the above problems by performing the following operations.

  The content information management unit 105 sorts a plurality of recorded contents to be displayed in the recorded content list. Here, the content information management unit 105 sorts the recorded content, for example, in the order of the date when the content was recorded or the program title of the recorded content.

  The display control unit 106 determines a recorded content to be selected and displayed among the plurality of recorded contents sorted by the content information management unit 105 in the recorded content list. When the display control unit 106 displays the recorded content list, the display control unit 106 continues the “recorded content last viewed by the user” and the “recorded content previously viewed by the user” among the plurality of recorded content. `` Recorded content '', `` Recorded content recorded after the time when the recorded content the user watched last time was recorded '', `` The most recorded content recorded after the time when the recorded content the user watched last time was recorded '' “Recorded content recorded in the past” or “recorded content searched in the past” is determined as the recorded content to be selected and displayed.

  The display control unit 106 displays the recorded content list on the screen of the display 109. At this time, the display control unit 106 displays the recorded content list so that the selected recorded content is always included in the screen.

  Further, when scrolling on the screen on which the recorded content list is displayed, the display control unit 106 circulates the recorded content displayed on the screen in a part of the plurality of recorded content.

  Next, an operation when the content management apparatus 101 according to the embodiment of the present invention sorts, determines, and displays a plurality of recorded contents on the screen will be described in detail with reference to the drawings.

  [Operation]

  FIG. 11 is a flowchart defining the sort, determination, display, and playback operation procedures for a plurality of recorded contents in the content management apparatus according to the embodiment of the present invention.

  The flowchart shown in FIG. 11 starts, for example, when the user presses a “recording list display” button on the user interface 107.

  Referring to FIG. 11, first, the user sets a sort condition when sorting a plurality of recorded contents to be displayed in the recorded contents list (step S1).

  Here, the sort condition is, for example, “in order of recording date / time” or “in order of program title”.

  The content management apparatus 101 may store the sort condition set by the user in step S1, and the content management apparatus 101 may continue to use the sort condition until the user changes the sort condition in step S1.

  Further, immediately after the user presses the “recording list display” button, the content management apparatus 101 may omit step S1 for setting the sort condition.

  Next, the content information management unit 105 (content sorting unit) selects a plurality of recorded contents recorded on the HDD 108 to be displayed in the recorded content list by using the members of the elements in the management table array in step S1. Sorting is performed based on the set sorting condition (step S2).

  When the number of recorded contents recorded in the HDD 108 exceeds the number of recorded contents that can be displayed on the display 109 by the display control unit 106, the recorded content list becomes a recorded content list over a plurality of pages.

  More specifically, since the entity of the recording date and time stored as a member of the element in the management table array is a double-precision real number type, the content information management unit 105 compares the recording date and time as members. The management table array can be sorted by recording date.

  That is, the content information management unit 105 can sort a plurality of recorded contents displayed in the recorded content list in order of recording date and time.

  Here, the content information management unit 105 may sort the elements of the management table array itself by repeatedly swapping the elements of the management table array during sorting, or refer to the element number of the management table array. An index array may be prepared and the index array may be sorted.

  Since the entity of the program title stored as a member of the element in the management table array is a character string type, the content information management unit 105 should use the size of the character code of the first character of the program title as a member. Thus, a plurality of recorded contents displayed in the recorded contents list can be sorted in the order of program titles.

  If the first characters of the two program titles to be compared are the same character, the content information management unit 105 may compare the second character, and if the second character is also the same character, If the fourth character is compared, the content information management unit 105 can sort the plurality of recorded contents displayed in the recorded content list in the order of the program titles.

  Some program titles include additional special characters defined by ARIB. Here, the additional special characters are 'S' characters surrounded by a square frame representing stereo broadcasting or 'two' characters surrounded by a square frame representing bilingual broadcasting.

  Since many program titles including additional special characters defined by ARIB include additional special characters at the beginning of the program title, when the sort condition is in program title order, the content information management unit 105 executes step S2. The sorting result is greatly affected by the additional special characters.

  For example, in the case where two recorded contents having the same program title and one includes an additional special character at the beginning of the program title but the other does not include the additional special character, the content information management unit 105 uses the above conditions. When step S2 is executed, the ranks of the two recorded contents having the same program title are greatly different in the sorted recorded contents list.

  When the content information management unit 105 sorts the program titles in the order of the program titles in step S2, in order to eliminate the influence of the additional special characters included in the program titles on the sorting, the content information management unit 105 selects the elements in the management table array. Sorting is performed using a character string obtained by removing additional special characters from a member program title character string.

  By the above procedure, the content information management unit 105 can eliminate the influence of the additional special characters included in the program title on the sorting.

  However, when the recorded content list is displayed on the display 110, there is no problem even if the display control unit 106 displays the program title including the additional special characters on the display 110.

  Next, the user sets a determination condition for determining a recorded content to be selected and displayed among a plurality of recorded contents recorded in the HDD 108 displayed on the recorded content list by the display control unit 106 (step S3). .

  The determination conditions are, for example, “recorded content that the user watched last time”, “recorded content that is a continuation of the recorded content that the user watched last time”, “recorded content that was recorded last time that the user watched” Recorded content ”,“ recorded content recorded in the past among the recorded content recorded after the time when the recorded content viewed by the user last time was recorded ”or“ recorded content searched in the past ”.

  The content management apparatus 101 stores the determination conditions set by the user in step S3, and the content management apparatus 101 uses the determination conditions until the user changes the determination conditions in step S3. You can continue.

  Further, immediately after the user presses the “recording list display” button, the content management apparatus 101 may omit step S3 for setting the determination condition.

  The display control unit 106 searches the recorded content that matches the determination condition set by the user in step S3 from the plurality of recorded content sorted by the content information management unit 105 in step S2. At this time, the display control unit 106 creates a search history list by storing the information related to the recorded content to be searched in the search order, and uses it for determining the recorded content to be selected and displayed later (step S4).

  Further, for example, even after the user deletes the recorded content searched for in the past and the recorded content is deleted from the recorded content list, the display control unit 106 displays information regarding the deleted recorded content in the search history list. You may leave it. In this case, the display control unit 106 can determine the recorded content to be selectively displayed based on the information related to the recorded content left in the search history list.

  Subsequently, the display control unit 106 determines the corresponding recorded content as the recorded content to be selectively displayed, and determines the rank in the recorded content list of the recorded content to be selectively displayed (step S5).

  Next, the display control unit 106 displays the recorded content list on the screen of the display 109. At this time, the display control unit 106 displays the recorded content list so that the recorded content selected and displayed in step S5, that is, the recorded content with focus is included in the screen (step S6).

  More specifically, the display control unit 106 calculates the number of pages in the recorded content list from which the recorded content to be selected and displayed is included based on the rank of the selected recorded content to be displayed.

  After the user presses the “recording list display” button, the display control unit 106 determines the page as the page of the recorded content list to be displayed first.

  Subsequently, the display control unit 106 outputs to the content information management unit 105 the program title, the recording date and time, and the viewed flag, which are members of the elements of the management table array necessary for rendering the page of the recorded content list. Give instructions.

  Upon receiving the output command from the display control unit 106, the content information management unit 105 outputs the program title, the recording date and time, and the viewed flag that are members of the elements of the management table array requested by the display control unit 106 to the display control unit 106. To do.

  Upon receiving the program title, the recording date and time, and the viewed flag that are members of the elements of the management table array from the content information management unit 105, the display control unit 106 renders the page of the recorded content list on the display 109.

  Next, the user confirms whether or not the recorded content requested by the user is displayed on the display 109 (step S7).

  When the recorded content requested by the user is displayed on the display 109 (YES in step S7), the user moves the focus to match the recorded content requested by the user by operating the cursor control button in the user interface 107. (Step S11).

  After confirming that the focus and the recorded content requested by the user match, the user operates the “play” button on the user interface 107. Subsequently, the content management apparatus 101 reproduces the corresponding recorded content on the display 109. At this time, the display control unit 106 creates a reproduction history list by storing the information related to the recorded content to be reproduced in the order of reproduction, and uses it for determining the recorded content to be selected and displayed later (step S12).

  Further, for example, even after the user deletes the recorded content that the user has viewed in the past and the recorded content is deleted from the recorded content list, the display control unit 106 displays information regarding the deleted recorded content in the playback history list. You may leave it. In this case, the display control unit 106 can determine the recorded content to be selectively displayed based on the information related to the recorded content left in the reproduction history list.

  When the content management apparatus 101 reproduces the corresponding recorded content to the end or when the user ends the reproduction (step S13), the process returns to step S4 for searching again, and the recorded content to be selected and displayed in the recorded content list. Search for.

  On the other hand, when the recorded content requested by the user is not displayed on the display 109 (NO in step S7), the user controls the display control unit 106 so that the recorded content requested by the user is displayed on the display 109. Whether to change the displayed page (step S8), whether to change the determination condition for determining the recorded content to be selected and displayed by the display control unit 106 (step S9), or when the content information management unit 105 performs sorting The sort condition is changed (step S10).

  More specifically, the user operates the “up arrow” button for cursor control in the user interface 107 to move the focus upward on the page of the recorded content list displayed on the display 109 by the display control unit 106. Following the movement to, the page displayed in the recorded content list can be moved to the previous page of the page (step S8). The details of the movement of the focus are the same as the procedure shown in FIG.

  Further, the user operates the “down arrow” button for cursor control on the user interface 107 to move the focus of the recorded content list displayed on the display 109 downward on the display 109 by the display control unit 106 downward. Subsequently, the page displayed in the recorded content list can be moved to the next page of the page (step S8). The details of the movement of the focus are the same as the procedure shown in FIG.

  The display control unit 106 receives the change of the page accompanying the movement of the focus by the user, returns to step S5, determines the recorded content to be selected and displayed, and then executes step S6 of displaying the recorded content list on the display. The user confirms whether or not the recorded content requested by the user is displayed on the page changed by the display control unit 106 displayed on the display 109 in step S7.

  Further, the user can change the determination condition when the display control unit 106 searches in step S4 by operating the “change determination condition” button in the user interface 107.

  For example, when the user changes the determination condition from “recorded content last viewed by the user” to “recorded content that is a continuation of the recorded content last viewed by the user”, the display control unit 106 changes the setting of the determination condition in step S3. In step S4, a search is performed using a new determination condition.

  Subsequently, the display control unit 106 sets a focus on the recorded content searched in step S5, and then displays the recorded content list on the display 109 in step S6.

  In step S7, the user confirms whether or not the recorded content desired by the user is displayed in the recorded content list displayed on the display 109.

  Further, the user can return the operation procedure to step S1 for setting the sort condition by operating the “sort condition change” button in the user interface 107 (step S10), and the content information management unit 105 can record the recorded content. Sorting conditions for sorting a plurality of recorded contents recorded in the HDD 108 displayed in the list can be changed.

  For example, when the user changes the sorting condition from “recorded date order” to “program title order”, the content information management unit 105 changes the setting of the sorting condition in step S1 for setting the sorting condition, and in step S2, a new setting is made. Sort using the sort condition to update the recorded content list.

  Next, the user changes the determination condition when the display control unit 106 searches in step S4 (step S3).

  When the content management apparatus 101 stores the previously used determination condition in step S4 for searching for recorded content to be selectively displayed, step S3 for setting the determination condition may be omitted.

  Subsequently, the display control unit 106 executes a search in step S4, sets the focus on the recorded content searched in step S5, and then displays the recorded content list on the display 109 in step S6.

  In step S7, the user confirms whether or not the recorded content desired by the user is displayed in the recorded content list displayed on the display 109.

  By such an operation procedure, the content management apparatus 101 displays the recorded content determined as the recorded content to be selected and displayed on the display 109, and the recorded content similar to the recorded content determined as the selected recorded content to be displayed on the display 109. Can be displayed.

  FIG. 12 is a diagram showing a display example of the recorded content list when the display control unit 106 in the content management apparatus according to the embodiment of the present invention determines the recorded content that was viewed last time as the recorded content to be selectively displayed.

  Referring to FIG. 12, when the user sets the sort condition as “recording date order” and sets the condition to be determined as the recorded content to be selected and displayed as “recorded content last viewed by user”, the user This is the fifth page of the recorded content list that is first displayed on the display 109 after the “recording list display” button in the interface 107 is pressed.

  Here, the recorded content that the user whose program title is “Criminal Drama Episode 7 Nanaboshi Detective” watched last time, that is, the element 1202e of the 41st list has the focus.

  Note that the number of recorded contents that can be displayed at one time by the content management apparatus 101 may be changed by the user according to preference. For example, in FIG. 12, the content management apparatus 101 displays nine recorded contents per page in the recorded content list on the display 109. However, for example, two recorded contents may be displayed per page in the recorded content list. . That is, the content management apparatus 101 displays, on the display 109, the recorded content determined as the recorded content to be selected and displayed for each page of the recorded content list and one recorded content arranged next to the recorded content. Also good.

  For example, when the user has forgotten the content of the recorded content that he / she watched last time and wants to recall the content by watching it again, when he / she slept in the middle of the program during the previous viewing, or even when he / she could not remember which recorded content he / she watched think of. Even in the above case, by using the content management apparatus 101, the user plays back the recorded content that was viewed last time without being forced to move the focus while reading the program title of the recorded content displayed in the recorded content list one by one. This can prevent the problems shown in FIGS. 6 and 7 from occurring.

  Furthermore, the content management apparatus 101 can selectively display the recorded content requested by the user in the recorded content list after sorting, and can also display the recorded content similar to the recorded content requested by the user in the recorded content list. Certain recorded content can be reminded to the user.

  For example, when the user wants to watch professional baseball, the user simply browses the recorded content list shown in FIG. 6 assuming that the display control unit 106 does not perform the selection display determination operation and the shortened circulation operation described above. The user recorded “Professional Baseball Koshien Hanshin VS Nippon Ham” recorded at 18:00 on June 9, 2011 (Thursday) as the third recorded content, or June 8, 2011 (Wednesday) as the seventh recorded content. ) “Professional Baseball Koshien Hanshin VS Nippon Ham” recorded at 18:00 is played.

  On the other hand, in the content management apparatus 101 according to the embodiment of the present invention, the recorded content list when the user shown in FIG. Can browse the “pro baseball Koshien Hanshin VS Lotte” recorded at 18:00 on May 23, 2011 (Monday), which is the 43rd recorded content. Therefore, the user records “professional baseball Koshien Hanshin VS Nippon Ham” recorded at 18:00 on Thursday, June 9, 2011, which is the third recorded content, or June 8, 2011, which is the seventh recorded content ( Wed) Before watching “Professional Baseball Koshien Hanshin VS Nippon Ham” recorded at 18:00, “Professional Baseball Koshien Hanshin VS Lotte” recorded on Monday, May 23, 2011, the 43rd recorded content ”, The recorded content can be viewed in chronological order of the recording date and time.

  FIG. 13 shows a display example of the recorded content list when the display control unit 106 in the content management apparatus according to the embodiment of the present invention determines the recorded content that follows the previously viewed recorded content as the selected recorded content. FIG.

  Referring to FIG. 13, the user sets the sort condition as “program title order”, and sets the condition for determining the recorded content to be selectively displayed as “recorded content that follows the recorded content that the user has watched last time”. When the user presses a “recording list display” button on the user interface 107, the page 8 is the eighth page of the recorded content list that the content management apparatus 101 first displays.

  Here, the recorded content that is a continuation of the recorded content that the user whose program title is “Night Drama Episode 5” last watched, that is, the element 1302h of the 71st list has the focus.

  For example, let us consider a case where the user forgets the program title name and the recording date and time of the previously viewed recorded content but wants to view the recorded content that is a continuation of the previously viewed recorded content. Even in the above-described case, by using the content management apparatus 101, the user is not forced to move the focus while reading the program titles of the recorded content displayed in the recorded content list one by one. It is possible to reproduce the recorded content that follows, and to prevent the problems shown in FIGS. 8 and 9 from occurring.

  For example, when the user searches for the recorded content having the program title “Night Drama”, the user simply reads the recorded content search list shown in FIG. Only information about the recorded content included in a part can be obtained.

  On the other hand, in the content management apparatus 101 according to the embodiment of the present invention, the user not only records contents including the phrase “night drama” as part of the program title, but also “super bowl”, “spy mission”. Information about the recorded content having the program title “Night Swing” can be obtained, and the problem shown in FIG. 10 can be prevented from occurring.

  If the series descriptor is valid in the recorded content that the user watched last time, the display control unit 106 uses the series identification, the number of stories, the expiration date, and the series name related to the recorded content to record the last time the user viewed it. It is easy to determine the recorded content that follows the content as the recorded content to be selectively displayed.

  Even when the series descriptor is not valid in the recorded content that the user watched last time, the display control unit 106 uses the basic information, the detailed information, and the genre information related to the recorded content in the EPG, so that the display control unit 106 It is easy to determine the recorded content that follows the content as the recorded content to be selectively displayed.

  For example, when the user finishes viewing the recorded content having the program title “Night Drama Episode 5” (step S13 in FIG. 11), the focus shifts to the recorded content whose program title is “Night Drama Episode 6”. (Steps S4 to S6 in FIG. 11). Therefore, the user can view the recorded content, which is a series of series, in the order of the number of stories in the series without taking time and effort.

  FIG. 14 shows a case where the display control unit 106 in the content management apparatus according to the embodiment of the present invention determines the recorded content recorded after the time when the recorded content viewed last time is recorded as the recorded content for selective display. It is a figure which shows the example of a display of a video recording content list.

  Referring to FIG. 14, the user sets the sorting condition as “recording date order”, and determines the condition to be determined as the recorded content to be selected and displayed is “recorded after the time when the recorded content the user watched last time was recorded”. This is the fifth page of the recorded content list that the content management apparatus 101 displays first after the user presses the “display recorded list” button on the user interface 107 when “recorded content” is set.

  Further, it is assumed that the recorded content whose program title is “criminal drama Episode 7 Nanaboshi Detective”, that is, the 41st list element 1402e is the previously viewed recorded content.

  For example, although a user has recorded a certain content in the content management apparatus 101 several months or years ago, the user does not intend to view the recorded recorded content but is unsure to delete the recorded content. Is left unviewed for a long time, the recorded content is not recorded, but is not the recorded content that the user wants to view.

  In other words, the user does not always want to watch all the recorded content recorded in the content management apparatus 101 in the unviewed state.

  In particular, the user has a low desire to view recorded content that has been left unviewed for a long period of time, and a strong desire to view unrecorded recorded content that has recently been recorded.

  Therefore, the recorded content that the user wants to view is a recorded content that is recorded after the time when the recorded content that the user viewed last time was recorded.

  In the recorded content list shown in FIG. 14, the user's viewing desire is recorded after the recorded content whose program title that the user previously viewed is “Detective Drama Episode 7 Nanaboshi Detective”, that is, after the element 1402e of the 41st list. Strong against recorded content.

  For example, in the recorded content list shown in FIG. 14, the recorded content recorded after the time when the recorded content that the user watched last time was recorded, and the recorded content that has not been viewed on Wednesday, May 25, 2011 (Wednesday) The recorded content whose program title recorded at 21:00 is “Merodrama Episode 4”, that is, the element 1402c of the 39th list may have the focus.

  For example, consider a case where the user has forgotten the previously viewed recorded content but wants to view the unviewed recorded content that he / she wants to watch in chronological order, that is, from the oldest. Even in the above case, by using the content management apparatus 101, the user is not forced to move the focus while reading the program titles of the recorded content displayed in the recorded content list one by one, and the recorded content that the user watched last time. Is a recorded content recorded after the recording time, and the recorded content in an unviewed state can be reproduced, and problems such as those shown in FIGS. 6 and 7 can be prevented from occurring.

  In addition, “Professional Baseball Koshien Hanshin VS Lotte” recorded at 18:00 on May 23, 2011 (Monday), which is the 43rd recorded content, and 21:00 on May 20, 2011 (Friday), which is the 44th recorded content. It is possible to remind the user that the recorded content “Babel Tower” has not been viewed.

  FIG. 15 shows the recorded content recorded in the past in the recorded content recorded after the time when the previously recorded recorded content was recorded by the display control unit 106 in the content management apparatus according to the embodiment of the present invention. It is a figure which shows the example of a display of a video recording content list when it determines as video recording content to selectively display.

  Referring to FIG. 15, the user sets the sorting condition as “recorded date order” and sets the condition for determining the recorded content to be selectively displayed as “recorded after the time when the recorded content that the user watched last time was recorded. When the user sets the “recorded content recorded in the past among recorded contents” and the user presses the “recorded list display” button on the user interface 107, the content management apparatus 101 first displays the recorded content list. The fifth page.

  Here, it is assumed that the recorded content whose program title is “criminal drama Episode 7 Nanaboshi Detective”, that is, the 41st list element 1502e is the previously viewed recorded content.

  For example, although a user has recorded a certain content in the content management apparatus 101 several months or years ago, the user does not intend to view the recorded recorded content but is unsure to delete the recorded content. Is left unviewed for a long time, the recorded content is not recorded, but is not the recorded content that the user wants to view.

  In other words, the user does not always want to watch all the recorded content recorded in the content management apparatus 101 in the unviewed state.

  In particular, the user has a low desire to view recorded content that has been left unviewed for a long period of time, and a strong desire to view unrecorded recorded content that has recently been recorded.

  Therefore, the recorded content that the user wants to view is a recorded content that is recorded after the time when the recorded content that the user viewed last time was recorded.

  In the recorded content list shown in FIG. 15, the user's desire to view is recorded after the recorded content whose last program title is “criminal drama Episode 7 Nanaboshi Detective”, that is, after the element 1502e of the 41st list. Strong against recorded content.

  For example, in the recorded content list shown in FIG. 15, the recorded content recorded in the past in the recorded content recorded after the time when the recorded content that the user viewed last time was recorded, and the recorded content that has been viewed. The recorded content whose program title recorded at 23:45 on Tuesday, May 24, 2011 is “Night Drama Episode 4”, that is, the element 1502d of the 40th list has the focus.

  For example, the user has forgotten the program title name and recording date and time of the recorded content that he / she watched last time, but the most recently recorded content recorded after the time when the previously recorded content was recorded Consider when you want to watch content. Even in the above case, by using the content management apparatus 101, the user is not forced to move the focus while reading the program titles of the recorded content displayed in the recorded content list one by one, and the recorded content that the user watched last time. Among the recorded contents recorded after the recording time, the recorded contents recorded in the past can be reproduced, and the problems shown in FIGS. 6 and 7 can be prevented from occurring.

  In addition, “Professional Baseball Koshien Hanshin VS Lotte” recorded at 18:00 on May 23, 2011 (Monday), which is the 43rd recorded content, and 21:00 on May 20, 2011 (Friday), which is the 44th recorded content. It is possible to remind the user that the recorded content “Babel Tower” has not been viewed.

  For example, when the user finishes viewing the recorded content having the program title “Night Drama Episode 4” (step S13 in FIG. 11), the focus shifts to the recorded content whose program title is “Mello Drama Episode 4”. (Steps S4 to S6 in FIG. 11). Therefore, the user can view the recorded content in chronological order without trouble.

  FIG. 16 is a diagram showing a display example of the recorded content list when the display control unit 106 in the content management apparatus according to the embodiment of the present invention determines the recorded content searched in the past as the recorded content to be selectively displayed. is there.

  Referring to FIG. 16, when the user sets the sort condition as “program title order” and sets the condition for determining the recorded content to be selected and displayed as “recorded content searched in the past”, the user This is the seventh page of the recorded content list that is first displayed by the content management apparatus 101 after the “recording list display” button in the interface 107 is pressed.

  For example, if a user searches in the past with the search key “Mello Drama Episode 2” and a recorded content whose program title is “Mello Drama Episode 2” is extracted by the search, the program title is “Mello Drama Episode 2”. The recorded content, that is, the element 1602g of the 61st list has the focus.

  For example, consider a case where the recorded content searched last time is a continuous drama, and the user wants to know the viewing state of a series of dramas and the number of stories recorded in the HDD 108 and the number of missing stories. Even in the above-described case, by using the content management apparatus 101, the user is not forced to move the focus while reading the program titles of the recorded content displayed in the recorded content list one by one. Thus, the number of stories recorded in the HDD 108 and the number of missing stories can be known, and problems such as those shown in FIGS. 8 and 9 can be prevented from occurring.

  For example, when a user searches for a recorded content having a program title “Melody Drama Episode 2”, if the user simply browses the recorded content search list, the user will use the phrase “Mello Drama Episode 2” as one of the program titles. Only information about the recorded content included in the section can be obtained.

  On the other hand, in the content management apparatus 101 according to the embodiment of the present invention, the user not only from the recorded content having the program title “Melodrama 2nd episode” but also from the 1st episode and the 3rd episode of “Mellodrama”. Episode 5 “Professional Baseball Koshien Hanshin VS Lotte” and “Squest Chart Big Release” can be obtained information about the recorded content, preventing the problem shown in FIG. Can do.

  FIG. 17 shows a problem when the display 109 displays the recorded content list sorted in order of the recording date and time on the assumption that the display control unit 106 does not perform the selection display determination operation and the shortened circulation operation described above. It is a 3rd figure for demonstrating.

  Referring to FIG. 17, the recorded content list is sorted in the order of recording date and time, the vertical axis represents the time axis, and the recorded content recorded in the past is shown in the lower part of the page. The total number of recorded contents is 80, and the recorded content list covers 9 pages.

  Consider a case where the content management apparatus 101 records a large amount of content after recording the recorded content requested by the user. That is, the recorded content requested by the user is the content of the program name “Mello Drama Episode 4” recorded at 21:00 on May 25, 2011 (Wednesday), and the content management apparatus 101 recorded the corresponding content. Assume that 43 contents are recorded later.

  FIG. 17 shows a recording that is first displayed by the content management apparatus 101 after the user presses the “recording list display” button on the user interface 107, assuming that the selection display determination operation and the shortened circulation operation are not performed. The first page of the content list is displayed, and then the user presses the “up arrow” button for cursor control in the user interface 107 to move the focus up by one, and then the content management apparatus 101 displays the display 109. It is a figure which shows the 9th page of the video recording content list displayed in FIG.

  Since the details of the movement of the focus are the same as the procedure shown in FIG. 4, the content management apparatus 101 displays the ninth page of the recorded content list on the display 109 and has the program title “New Year's Eve! The recorded content, that is, the element 1702h of the 80th list has the focus.

  For example, although a user has recorded a certain content in the content management apparatus 101 several months or years ago, the user does not intend to view the recorded recorded content but is unsure to delete the recorded content. Is left unviewed for a long time, the recorded content is not recorded, but is not the recorded content that the user wants to view.

  In other words, the user does not always want to watch all the recorded content recorded in the content management apparatus 101 in the unviewed state.

  In particular, the user has a low desire to view recorded content that has been left unviewed for a long period of time, and a strong desire to view unrecorded recorded content that has recently been recorded.

  Therefore, the recorded content that the user wants to view is a recorded content that is recorded after the time when the recorded content that the user viewed last time was recorded.

  For example, “Follow the tuna” recorded at 19:00 on February 18, 2011 (Friday), which is the 74th recorded content shown in FIG. 17, and January 9, 2011 (Sunday), 12th, which is the 77th recorded content. Recorded content with a program title of “Yearly Comedy Japanese Islands” that was recorded at the time, and the 79th recorded content with a program title of “Year-forgotten Variety Special” recorded at 23:00 on December 31, 2010 (Friday) is not yet viewed However, the user's desire for viewing is low.

  Therefore, when the user moves the focus in the recorded content list via the user interface 107 in order to select the recorded content that the user wants to view, for example, the recorded content with a low user's viewing desire as shown in FIG. By restricting the movement of the focus in the recorded content list so as not to have the focus, it is possible to prevent the user from moving the focus in the recorded content list in vain.

  FIGS. 18 and 19 show the focus in the recorded content list when the user presses the cursor control button on the user interface 107 in the content management apparatus according to the embodiment of the present invention. 5 is a flowchart that defines an operation procedure when performing a movement process and a display process of a recorded content list.

  That is, FIG. 18 and FIG. 19 are flowcharts defining an operation procedure in which the content management apparatus 101 limits the movement of focus in the recorded content list by shortening circulation.

  The flowchart shown in FIG. 18 is started when the user presses an “up arrow” button for cursor control in the user interface 107.

  Referring to FIG. 18, the user interface 107 monitors the pressing of the “up arrow” button for cursor control in the user interface 107 by the user (step S1801).

  Next, when the user interface 107 detects that the user has pressed the “up arrow” button for cursor control on the user interface 107, the user interface 107 transmits a focus up movement command to the display control unit 106 (YES in step S1801).

  Next, the display control unit 106 that has received the focus up movement command from the user interface 107 confirms the current list index and displays the display of the list element corresponding to the current list index displayed on the display 109 from the outline. Change to black (step S1802).

  Next, the display control unit 106 searches for a list index of the shortened circulation destination (step S1803). For example, when the user designates the shortened circulation destination as “recorded content that the user watched last time”, the display control unit 106 searches the recorded content list for the recorded content that the user watched last time, and the corresponding recorded content Set the rank of to the list index of the shortened circulation destination.

  Next, the display control unit 106 checks the current list index and determines whether or not the current current list index is equal to 1 (step S1804).

  Next, when the display control unit 106 determines that the current list index is equal to 1 (YES in step S1804), the display control unit 106 sets the current list index as the list index of the shortened circulation destination and stores it (step S1805).

  The display control unit 106 acquires information necessary for displaying the shortened circulation destination page from the content information management unit 105 (step S1806).

  Next, the display control unit 106 deletes the page of the recorded content list currently displayed on the display 109 (step S1807).

  Next, the display control unit 106 draws the shortened circulation destination page in the recorded content list based on the information received from the content information management unit 105 (step S1808), and subsequently displays the elements of the shortened circulation destination list. Is changed from black to white (step S1814), and the process of moving the focus to the shortened circulation destination is completed.

  On the other hand, if the display control unit 106 determines that the current list index is not equal to 1 (NO in step S1804), the display control unit 106 performs operations equivalent to the operations in steps S43 to S47 shown in FIG. 4 (steps S1809 to S1813). ).

  Next, the display control unit 106 executes step S1814, and the focus upward movement process is completed.

  The flowchart shown in FIG. 19 starts, for example, when the user presses a “down arrow” button for cursor control in the user interface 107.

  Referring to FIG. 19, the user interface 107 monitors the pressing of the “down arrow” button for cursor control on the user interface 107 by the user (step S <b> 1901).

  Next, when the user interface 107 detects that the user has pressed the “down arrow” button for cursor control in the user interface 107, the user interface 107 transmits a focus down movement command to the display control unit 106 (YES in step S1901).

  Next, the display control unit 106 that has received the move-down-focus command from the user interface 107 confirms the current list index, and displays the display of the list element corresponding to the current list index displayed on the display 109 from the outline. Change to black (step S1902).

  Next, the display control unit 106 searches for a list index of the shortened circulation destination (step S1903). For example, when the user designates the shortened circulation destination as “recorded content that the user watched last time”, the display control unit 106 searches the recorded content list for the recorded content that the user watched last time, and the corresponding recorded content Set the rank of to the list index of the shortened circulation destination.

  Next, the display control unit 106 checks the current list index, and determines whether the current list index is equal to the shortened circulation destination list index (step S1904).

  Next, when the display control unit 106 determines that the current list index is equal to the shortened circulation destination list index (YES in step S1904), the display control unit 106 sets the current list index to 1 and stores it (step S1905).

  The display control unit 106 acquires information necessary for displaying the first page of the recorded content list from the content information management unit 105 (step S1906).

  Next, the display control unit 106 deletes the page of the recorded content list currently displayed on the display 109 (step S1907).

  Next, the display control unit 106 draws the first page in the recorded content list based on the information received from the content information management unit 105 (step S1908), and subsequently displays the elements of the first list as black. The blank is changed to blank (step S1914), and the movement process to the element of the first list of focus is completed.

  On the other hand, if the display control unit 106 determines that the current list index is not equal to the shortened circulation destination list index (NO in step S1904), the display control unit 106 performs an operation equivalent to the operation in steps S53 to S57 shown in FIG. Step S1909 to Step S1913).

  Next, the display control unit 106 executes step S1914, and the downward movement process of the focus is completed.

  As described above, when scrolling on the display 109 on which the recorded content list is displayed, the display control unit 106 circulates the recorded content displayed on the display 109 within a part of the plurality of recorded content. The action can be performed.

  For example, even when the user displays the recorded content list on the display 109 when it is assumed that the display control unit 106 does not perform the above-described selection display determination operation, the user can record the recorded content list by using the shortened circulation. It is possible to find the recorded content that the user wants to view without being forced to move the focus while reading the program title of the recorded content that is displayed on the screen with low viewing desire.

  For example, when the recorded content list in the content management apparatus 101 is set to shortened circulation, after the user presses the “display recording list” button in the user interface 107, the content management apparatus 101 performs the first operation shown in FIG.
