  Embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

  With reference to FIG. 1, the structure of the hard disk recorder 100 which concerns on embodiment of this invention is demonstrated. FIG. 1 is a block diagram showing a hardware configuration of hard disk recorder 100. The hard disk recorder 100 is an aspect of the information recording / reproducing apparatus according to the present invention, and is not limited to this. For example, it may be a device having a function of recording video data on a DVD (Digital Versatile Disk) recorder or other removable recording medium.

  As shown in FIG. 1, the hard disk recorder 100 receives signals from an operation unit 122 for receiving an instruction input from outside and outputting a signal corresponding to the instruction, and a remote controller (not shown). A light receiving unit 124 for receiving and outputting a command according to the signal, a clock circuit 126 for measuring the time of the hard disk recorder 100 and outputting a signal according to the time, and the operation of the hard disk recorder 100 And a display unit 128 for displaying the state to the outside. Here, the state of operation means, for example, whether the hard disk recorder 100 is reproducing or recording.

  The hard disk recorder 100 is further connected to an antenna 190, a tuner 130 for receiving a broadcast signal and EPG data based on a channel instructed to select a channel, and video data of the broadcast signal received by the tuner 130 according to MPEG2 (Moving Picture Experts Group 2) System control for executing predetermined processing based on MPEG encoder 132 for conversion to the format and output, and signals input from outside and data stored in advance in the interior Circuit 110.

  The hard disk recorder 100 is further output from the hard disk device 140, the MPEG decoder 136 for restoring the data output from the system control circuit 110, which is video data compressed in the MPEG2 format, and the system control circuit 110. An OSD (On Screen Display) image generation circuit 114 for generating an image to be displayed on a video display unit based on information representing an operation state of the hard disk recorder 100 and predetermined data, and an MPEG decoder 136. An output unit 138 that combines the output data and the data output from the OSD image generation circuit 114 and outputs a signal for displaying a video is included.

  The hard disk recorder 100 is connected to the television 150 at the output unit 138 via a cable (not shown). The hard disk device 140 includes a data recording / reproducing head 142 for recording and reproducing data and a hard disk 144 for storing data.

  The EPG data received by the tuner 130 includes, for example, data indicating a program name, a broadcast channel, a broadcast time zone, a genre, and the like for a broadcast program. The program name acquired from the EPG data is hereinafter referred to as “EPG title”.

  In the present embodiment, the EPG data is obtained by being received by the tuner, but is not limited to this, and may be EPG data obtained by downloading from an external network such as the Internet. .

  Here, an example of the contents of the hard disk 144 will be described. Referring to FIG. 3, hard disk 144 includes a system area E1 and a data area E2. Information including the database 31 and the title management table 32 is stored in the system area E1. In the data area E2, video data based on the broadcast signal received by the tuner 130 is stored.

  Referring to FIG. 4, an EPG title is stored in area T1 of database 31, and a title set by the user (hereinafter referred to as “user title”) is stored in area T2. In the database 31, the EPG title and the user title are stored in association with each other. For example, in FIG. 4, “OxOxOx” (title t41) is stored in the region T1, and “Ox” (title t42) is stored in the region T2. Note that such a user title setting method (title editing method) will be described in detail later. The database is managed by, for example, an LRU (Least Recently Used) method or a FIFO (First In First Out) method.

  Although the database 31 has been described as being stored in the hard disk 144 in the present embodiment, the present invention is not limited to this. For example, a flash memory in the memory 112 or a new flash memory may be provided and stored.

  Referring to FIG. 5, title information is stored in the title management table 32 for each broadcast program as data stored in the data area E2. In the present embodiment, as title information, at least a title name is stored in area D1, a start address is stored in area D2, an end address is stored in area D3, and an EPG title is stored in area D4.

  Next, video data recording processing in the hard disk recorder 100 according to the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing a procedure of video data recording processing executed by the system control circuit 110 of the hard disk recorder 100 according to the embodiment of the present invention.

  Referring to FIG. 2, first, system control circuit 110 obtains an EPG title of a broadcast program to be recorded from EPG data received by tuner 130 (step S101).

  Next, the system control circuit 110 searches whether the EPG title acquired in step S101 is stored in the database 31 (step S102). Here, when searching the database 31 using the acquired EPG title, it is possible to perform a fuzzy search in consideration of the fact that the program is a special program or the like.

  When it is detected that the EPG title acquired by the system control circuit 110 is stored in the database 31 (YES in step S102), the corresponding user title is registered in the title management table 32 as a title name (step S103). For example, when the acquired EPG title is the title t41, the system control circuit 110 searches the database 31 in FIG. 4 and detects that the same title t41 is stored in the region T1. Then, the title t42 “Ox” in the area T2 stored in association with t41 is read as the title name. Then, referring to FIG. 5, system control circuit 110 stores in area D <b> 1 of title management table 32. The EPG title t41 acquired at the same time is also stored in the area D4.

  As described above, in the recording, the replaced user title is stored in the area D1 of the title management table 32.

  On the other hand, when the system control circuit 110 detects that the acquired EPG title is not stored in the database 31 (NO in step S102), the acquired EPG title is registered in the title management table 32 as a title name (step S104). For example, when the acquired EPG title is “ΔΔΔ ○ □” (title t101), the system control circuit 110 searches the database 31 and detects that there is no same title name in the region T1. Then, referring to FIG. 5, the title t101 is stored in both the area D1 and the area D2 of the title management table 32. Note that the EPG title may be stored in the area D2 only when the user title is stored in the area D1.

  After the processing in step S103 or S104 described above, the system control circuit 110 performs video data recording processing (step S105). That is, the video data is stored in the data area E2 of the hard disk 144 via the antenna 190, the tuner 130, and the MPEG encoder 132.

  As described above, the title management table 32 creates title information of video data (hereinafter referred to as “recording data”) recorded in the data area E2 for each broadcast program.

  Next, the procedure of the title list display process executed by the system control circuit 110 in the hard disk recorder 100 according to the present embodiment will be described using the flowchart shown in FIG. When the user reproduces the recorded data, the process shown in FIG. 6 is performed.

  When the system control circuit 110 detects a command signal for title list display (YES in step S111), the system control circuit 110 reads the title name for each recording data from the area D1 of the title management table 32 (step S112). Graphic data for display is generated using the read title name, and is supplied to the OSD image generation circuit 114. Then, a title list screen is displayed on the television 150 via the output unit 138 (step S113).

  FIG. 8 is an example of a title list display screen displayed on the television 150 in step S115. Referring to FIG. 8, a list of title names read from area D1 of title management table 32 is displayed in area 81. In FIG. 8, for example, four programs are displayed based on the title management table 32 shown in FIG. In FIG. 8, the title t101 “ΔΔΔ ◯ □” and the title t42 “Ox” stored in the area D1 in FIG. 5 are displayed. In the area 82, a button “Edit Title” is displayed in the area 81.

  Thus, when the title of the area D1 of the title management table 32 is read as it is in the area 81, the user title is displayed, for example, as the title t42.

  When displaying the title of the recorded data, it is possible to search whether or not the EPG title recorded in the area D4 exists in the database 31, and if it exists, the title name of the area D1 may be updated. . Then, the latest title name can be displayed even when the user title is corrected a plurality of times by the title editing process described later.

  Next, the procedure of title editing processing executed by the system control circuit 110 in the hard disk recorder 100 according to the present embodiment will be described using the flowchart shown in FIG. This title editing process is performed when the system control circuit 110 detects an instruction for the title editing process via the light receiving unit 124 after the title list display (step S113) is performed in the title list display process shown in FIG. To begin. For example, the process is started in response to the user specifying the “Edit title?” Button shown in the area 82 in FIG. 8 by operating the remote controller (not shown).

  Referring to FIG. 7, system control circuit 110 determines whether a title to be edited has been designated. The system control circuit 110 stands by until it is detected that a title has been designated via the light receiving unit 124 (NO in step S131).

  When the system control circuit 110 detects that a title has been designated via the light receiving unit 124 (YES in step S131), the system control circuit 110 causes the television 150 to display an editing screen of the designated title (hereinafter referred to as “designated title”) ( Step S132). Then, input of characters by the user is accepted until the end of title editing is detected (NO in steps S133 and S134).

  When the system control circuit 110 detects the end of title editing (YES in step S134), the system control circuit 110 reads the EPG title stored in the area D4 of the title management table 32 of the designated title, and whether the EPG title is stored in the database 31. Search is performed (step S135). If it is detected that the read EPG title is stored in area T1 of database 31 (YES in step S135), the user title in area T2 stored in association with the EPG title is updated (step S136).

  If it is detected that the read EPG title is not stored in the region T1 of the database 31 (NO in step S135), the EPG title is associated with the changed title (user title), and the region T1 and the region T2 are associated with each other. Each is registered (step S137).

  Subsequently, the system control circuit 110 updates the title name in the title management table 32 (step S138). Here, the same title as the EPG title stored in the updated or newly registered database 31 updates all the recording data stored in the area D4 of the title management table 32. That is, the title name stored in the area D1 of the title management table 32 is updated with the changed title (user title). If there is no other recorded data having the same EPG data, only the recorded data designated by the user is updated.

  Then, the designated title is switched to the title updated in step S138 and displayed on the television 150 (step S139).

  When it is detected that the next title has been designated via the light receiving unit 124 (YES in step S140), the system control circuit 110 repeats the processes in steps S132 to S139 for the designated title. When a title editing end instruction is detected via light receiving unit 124 (NO in step S140), the title editing process ends.

  Next, specific examples of such title editing processing will be described with reference to FIGS. As a premise of this specific example, description will be made using the database 31 shown in FIG. 4 and the title management table 32 shown in FIG.

  9 and 10 are examples of screens displayed on the television 150 during the title editing process. FIG. 9A is the same screen as the title list display screen shown in FIG. 8, and the user operates the remote controller (not shown) to specify the “Edit title?” Button shown in the area 82. FIG. FIG. 9B is an example of a screen displayed subsequent to the screen shown in FIG.

  Referring to FIG. 9B, a list of recorded titles is displayed in area 81 as in FIG. 9A. A message “Please specify the title you want to edit the title name” is displayed in area 91, and an end button is displayed in area 92.

  When the user operates a remote controller (not shown) according to the message shown in area 91 and designates the title whose title name is to be edited (YES in step S131), the designated title editing screen as shown in FIG. 10 is displayed. It is displayed (step S132).

  Referring to FIG. 10, the current title name is displayed in area 11, and the changed title name is displayed in area 12. In the area 13, a list of characters used for editing the title is displayed. In the area 14, a button for finishing title editing is displayed. Note that the character list displayed in the area 13 may include graphics, symbols, and the like other than characters.

  If the title specified in step S131 is the title t101 shown in the area 81 of FIG. 9B, the title t101 “ΔΔΔ ◯ □” is displayed in the area 11. The user operates a remote controller (not shown) to specify a character from the character list displayed in the area 13. The characters designated by the user are sequentially displayed in the area 12 shown in FIG. 10 (step S133).

  When the title edit end button shown in area 14 is selected by the user, the characters displayed in area 12 become the changed title (YES in step S134). In FIG. 10, the changed title is, for example, title t102 “Δ ○ □”.

  When the editing of the title by the user is completed, it is searched whether the EPG title t101 stored in the title information area D4 of the designated title is stored in the database 31 (step S135). If EPG title t101 is stored in area T1 of database 31 shown in FIG. 4 (YES in step S135), the user title associated and stored in area T2 is updated (step S136).

  On the other hand, if the EPG title t101 does not exist in the area T1 of the database 31 shown in FIG. 4 (NO in step S135), it is newly registered (step S137). In this case, referring to FIG. 12, title t101 “ΔΔΔ □□” is stored in region T1 of database 31, and title t102 “ΔΔ □” is stored in region T2. In this way, the user title is set.

  Next, the EPG title t101 updates the title name stored in the area D1 for the recording data stored in the area D4 of the title management table 32. Then, the title t101 “ΔΔΔ ○ □” stored in the area D1 in FIG. 5 is rewritten to the title t102 “Δ ○ □” with reference to FIG. 11 (step S138).

  Then, as shown in FIG. 13, the updated title t102 is displayed on the television 150 (step S139). Compared with the screen before the title editing process shown in FIG. 9B, the title name of the second title displayed in the area 81 is changed from the title t101 “ΔΔΔ ○ □” to the title t102 “Δ ○ □”. Has been changed to In this way, the title name desired by the user is displayed.

  When the user again designates one of the titles shown in area 81 (YES in step S140), the title editing screen as shown in FIG. 10 is displayed again (step S132). When the user designates the end button shown in area 92 (NO in step S140), the title editing process ends. FIG. 13 shows that the user has designated the end button shown in area 92.

  In the present embodiment, the title editing process is provided as an interruption process when the title list of the recorded data is displayed. However, for example, a title registration mode may be provided before recording. In this case, the user title set in the title registration mode is registered / updated in the database 31 in association with the EPG title.

  As described above, since the EPG data is stored in the area D4 of the title management table 32, the latest title name can be reliably displayed regardless of how many times the title name in the area D1 is changed.

  Further, for example, when the title name is displayed on a part of the screen of the television 150 when the recorded data is reproduced, the user title can be displayed. Therefore, the user can view the recorded data comfortably.

  In the present embodiment, the EPG data is stored in the area D4 of the title management table 32 so that the title name can be updated no matter how many times the title is changed. However, the present invention is not limited to this. For example, all the user titles set or changed by the user in the database 31 may be registered, and it may be searched whether the corresponding title exists.

  In addition, when the title is edited by the user, the title after the change is displayed as the title name all the time thereafter, but the user may be allowed to select whether or not this time is limited. In this case, for example, when the user inputs an instruction to be limited to this time, the process proceeds to step S138 without performing the processes of steps S135 to S137 in FIG. In step S138, only the recording data designated by the user is updated.

  The title name in the area D1 of the title management table 32 may be an EPG title, and the database 31 may be searched only when recording data is displayed. In this case, if the EPG title stored in the area D1 exists in the database 31, the system control circuit 110 replaces it with the corresponding user title and displays it. Therefore, it is not necessary to search the database 31 when recording.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
