Patent Document 2: Japanese Patent Laid-Open No. 2009-16959

Summary of the invention

However, since the existing full-automatic recorder starts and ends the recording of each channel at the same time according to the time period (start time, end time) set by the user, the broadcast that spans this time period (recording start time or end time) The program is recorded as missing the opening or ending. When the user watches the program later, there is a case where part of the program is not visible.

For example, if the recording start time reservation is set to 21:00 in the recording setting of the time zone of the time shift function, the title of the program starting from 20:50 will be cut off. For a structured program, you can't see the "start" part and don't understand the background of the TV series, which leads to dissatisfaction. In addition, when the user sets the recording end time to 22 during the recording setting of the time period, the end of the program ending at 22:10 will be cut off. Similarly, the "end" part will not be seen. Understanding very important endings can also lead to dissatisfaction.

The problem to be solved by the present invention is to provide an electronic device and a program recording method, which can prevent the occurrence of the situation where the programs that overlap in the recording start time and / or the recording end time recorded in the time period are scratched.

The electronic device of the embodiment includes a first recording reservation information storage unit, a second recording reservation information storage unit, a reservation control unit, and a recording unit. The first recording reservation information storage unit stores first recording reservation information, and the first recording reservation information is used to reserve and record programs broadcast on multiple channels together at a specified time period. The second recording reservation information storage section stores second recording reservation information, which is used to assist the start / end of scheduled recording of the first recording reservation information. The reservation control unit extracts the broadcast information of the program from the acquired program information of the scheduled broadcast, generates second recording reservation information, and stores it in the second recording reservation information storage unit, where the second recording reservation information crosses the broadcast The scheduled recording start time and / or end time of the program at the recording start time and / or recording end time of the time period is corrected to the broadcast time of the program; that is, the second recording reservation information is used at the scheduled recording start time and / Or the end time exceeds the program broadcast time period, or the broadcast start time and / or the broadcast end time exceeds the program scheduled recording time period, the scheduled recording start time and / or end time is corrected to the program's broadcast start time Time and / or broadcast end time; that is, the second recording reservation information is used to record the recording start time and / or recording end time of the program when the broadcast time of the program crosses the reserved time period, Corrected to the broadcast moment of the program. Where the scheduled recording start time and / or end time spans the program broadcast time period, it means that the scheduled recording start time and / or end time is within the program broadcast time period; the broadcast start time and / or broadcast end time spans the program recording time period, It means that the broadcast start time and / or the broadcast end time is within the scheduled recording time period. The recording unit can record programs broadcast on multiple channels, and record the programs based on the first and second recording reservation information.

The broadcast time of the program spans the reserved time period specified by the fully automatic recording reservation table 67a, and may mean that the broadcast start time and / or broadcast end time of the program is not within the reserved time period specified by the fully automatic recording reservation table 67a. Unless otherwise specified, in each embodiment of the present application, the broadcast (broadcast time) spans the time period (reservation time period), which means that the broadcast start time and / or the broadcast end time are not within the time period (reservation time period) .

In this example, the broadcast of the program "Variety A" of the program ID "30022" spans the recording start time "19:00" in the fully automatic recording time period of the recording reservation on the recording day "2018/9/4", so Set an appointment for retrospective recording to advance the recording start time of the channel to the broadcast start time “18:50” of the program “Variety A”. In the auxiliary reservation table 67b, the broadcast end time of the program "Variety A" does not cross the recording end time of the fully automatic recording time period, so it is recorded as "-" without setting. Without setting "-", since the recording takes priority over the time period of the fully automatic recording reservation table 67a, the recording time of this channel becomes from the broadcast start time "18:50" to the recording end time "22:00 ".

In addition, the broadcast of the program "Movie B" of the program ID "30043" spans the recording end time "22:00" in the fully automatic recording time period of the recording reservation on the recording day "2018/9/4" and ends at the broadcast end time "22:30" ends, so set a reservation for extended recording to delay the end of the channel's recording until "22:30". In the auxiliary reservation table 67b, the broadcast start time of the program "Movie B" does not cross the recording start time of the fully automatic recording time period, so it is recorded as "-" without setting. Without setting "-", since the recording takes priority over the time period of the fully automatic recording reservation table 67a, the recording time of this channel becomes from the broadcast start time "19:00" to the recording end time "22:30 ".

Furthermore, since the broadcast of the program "Special Program C" of the program ID "30062" spans the recording start time "19:00" and the recording end in the fully automatic recording time period of the recording reservation on the recording day "2018/9/4", respectively Time "22:00", so set a retrospective recording reservation to advance the channel's recording start time to the broadcast start time "18:30" of the program "Special Program C", and set an extension recording reservation to end the recording The time is delayed until the broadcast end time "23:00" of the program "Special Program C".

In addition, the storage device 67 also stores (stores) a recording reservation table (not shown) for individual program reservation recording, which is a user-specified channel (or program name) and date and time.

The generated program table data (EPG data) is converted into a program table display signal by the OSD processing unit 24, and is output by the display control unit 25.

In addition, the program table generation unit 58 allows the user to perform a time-shift machine history program table display operation during program playback, etc., based on the attribute information of the recorded program acquired by the program information acquisition unit 57 and the recording information table 67c (see FIG. 5). The recording information generates program table data (time-shift machine history program table data) for displaying the recorded program table displayed on the display 26 via the OSD processing unit 24. That is, if the user performs a time-shift machine history program table display operation at a time such as when a program is broadcast, the program table generation unit 58 generates the display 26 for display on the display 26 via the OSD processing unit 24 based on the attribute information and the recording information. The above program table data.

When generating the program table data, the program table generation unit 58 adds and displays the program field of the program whose recording flag 67c satisfies the condition in the program field included in the data and the establishment flag of the recording information table 67c is "1" Incomplete (incomplete) marks (such as triangle marks, extended marks and other symbols, characters, etc.). That is, a mark indicating that the program is not established (incomplete) as a content is added and displayed in the program column that meets the conditions.

The OSD processing unit 24 converts the time-shift machine history program table data into a program table display signal, outputs it to the display 26 through the display control unit 25, and displays it as a time-shift machine history program table 301 (see FIG. 9) on the screen of the display 26. That is, the program table display signal is displayed on the screen of the display 26 as the time-shift machine history program table 301.

The time-shift machine history program table data is a list for playing back recorded programs having one or more program columns 221, 222, 223 (refer to FIG. 9), etc. The one or more program columns are based on attributes that store recorded programs Information (program information at the time of recording a program) recording information table 67c recording information to display the program information (program content, artist and other EPG (electronic program table) information including the title (program name) of the recorded program that can be played Part of the information). The time-shift machine history program table 301 shown in FIG. 9 is an example of a display manner in which the list is formed in a table format in a vertical and horizontal program column. In the time-shift machine history program table 301, even programs that exceed the time period recorded in the fully automatic recording mode are normally recorded as indicated by the frame 310.

On the other hand, in this recording and playback device 1, although some programs can be remedied by retrospecting and extending the recording time, sometimes a program that does not satisfy the content of the program is recorded as the content that is not established. At this time, as shown in FIG. 11, in a plurality of program columns, a flag 303 indicating that the program is not established as a content is added to the program column 302 of the program that satisfies the condition. That is, in the plurality of program columns shown in FIG. 11, in the program column 302 corresponding to the program that satisfies the condition, a mark 303 indicating that the program is not established as a content is added.

The program determination unit 60 reads the condition that the program stored in the storage device 67 does not hold, determines whether the recorded program satisfies the read condition, and records the flag indicating the determination result in the program ID in the recording information table 67c In the column of the establishment logo. As a flag, it is recorded as "1" when the condition that the program is not satisfied is satisfied, and as "0" when the condition is not satisfied. In addition, the conditions may not be stored in the storage device 67, but may be set in the program determination unit 60 in advance. In this case, the program determination unit 60 determines whether the program as content is not established (incomplete) by determining whether the recording information of the recorded program satisfies the preset condition.

Under the control of the CPU 52, the reservation control unit 59 outputs user instructions (operation inputs) of individual programs in the EPG (program table) of the EPG (program table) of the display 26 via the OSD processing unit 24 based on the EPG data generated by the program table generation unit 58 to accept A recording reservation for recording the program is reserved, and then recording reservation information is generated and stored in the storage device 67. That is, the reservation control unit 59 may use a user instruction (operation input) for an individual program in the EPG (program table) as a recording reservation operation for recording the program, and then generate recording reservation information and store it in the storage device 67 .

Specifically, the reservation control unit 59 sets the time period of the operation input in the fully automatic recording reservation table 67a (refer to FIG. 2). In addition, the recording reservation information may be stored in RAM54 or NVM55.

The recording reservation information of the fully automatic recording reservation table 67a is used to record the time period (recording start time, recording end time) in which the playback processing unit 56 records the programs of all channels together. As an option, you can also choose not to record some channels. In addition, an example in which the recording reservation information of the fully automatic recording reservation table 67a uses a pair of time periods of the start time and the end time is shown, but a plurality of tables may be prepared and a plurality of time periods may be set. That is, the above only shows an example of a fully automatic recording reservation table, but in actual use, it is also possible to set a plurality of fully automatic recording reservation tables and set different time periods respectively.

In addition, the reservation control unit 59 sets the recording reservation information of the program that needs to be corrected in the time period of the fully automatic recording reservation (first recording reservation information) in the auxiliary reservation table 67b. Auxiliary recording reservation information (second recording reservation information) is stored in the auxiliary reservation table 67b, and the auxiliary recording reservation information is used for recording reservations for the fully automatic recording reservation (first recording reservation information) per channel (each program) The start / end of the calibration is performed (auxiliary).

In detail, the reservation control unit 59 extracts the broadcast information of the program (the broadcast start time of the program, the broadcast end from the program data (EPG information) of the scheduled broadcast acquired by the program information acquisition unit 57 at the time of startup or at regular intervals Time), compare the broadcast information with the recording start time and / or recording end time of the fully automatic recording reservation time period, and generate the recording start time and / or the scheduled recording of the program that broadcasts across the fully automatic recording reservation time period The recording end time is corrected to the auxiliary recording reservation information (second recording reservation information) of the broadcast time of the program, and then stored in the auxiliary reservation table 67b. That is, the reservation control unit 59 generates auxiliary recording reservation information, and then stores the auxiliary recording reservation information in the auxiliary reservation table 67b. The auxiliary recording reservation information is used when the recording start time and / or recording end time of the scheduled recording is not started from the broadcast. During the time period from the time to the broadcast end time, the recording start time and / or recording end time of the scheduled recording is corrected to the broadcast start time and / or broadcast end time of the program, and then stored in the auxiliary reservation table 67b .

The reservation control unit 59 generates auxiliary recording reservation information that sets the broadcast start time of the program that starts before the recording start time in the time period set in the fully automatic recording reservation table 67a, and sets it in the auxiliary In the reservation table 67b.

In addition, the reservation control unit 59 generates auxiliary recording reservation information that sets the broadcasting end time of the program that ends after the recording end time in the time period set in the fully automatic recording reservation table 67a as the recording end time, and sets In the auxiliary reservation table 67b.

When the interval between the recording time of the time zone of the fully automatic recording reservation table 67a and the broadcasting time of the program is within a predetermined allowable time (threshold time M), the reservation control unit 59 generates a corrected fully automatic recording reservation The auxiliary recording reservation information of the reserved recording information (recording start time and recording end time) of Table 67a, and when the allowable time period is exceeded, auxiliary recording reservation information is not generated, that is, second recording reservation information is not generated.

In addition, each of the above-mentioned record playback processing unit 56, program information acquisition unit 57, program table generation unit 58, reservation control unit 59, and program determination unit 60, or at least one, or any number of them may be the firmware of the CPU 52 .

The CPU 52 accepts an operation input from the remote controller 71 on the screen displayed on the display 26, and the operation input of the remote controller 71 is displayed with a color button ("blue" button display, "red") that accepts operation input for a specific function Button display, "green" button display and "yellow" button display: not shown) correspond to each other. That is, the CPU 52 determines that the operation of any one of the "blue" key 71B, the "red" key 71R, the "green" key 71G, and the "yellow" key 71Y of the remote controller 71 corresponds to a button of a specific color displayed on the screen Instruction and accept the instruction corresponding to the operation input of the key.

Here, two program tables (a program table for broadcasting viewing and recording reservation and a program table for viewing recorded programs) generated by the program table generating unit 58 will be described. FIG. 3 shows an example of the display of the EPG (program table of current and future broadcast programs: future program table) corresponding to the program table data (EPG information) generated by the program table generation unit 58.

As shown in FIG. 3, the EPG 200 is provided with a channel display column 201-206 (channel axis) for displaying programs broadcast by a predetermined number of channels (broadcast stations), a time period display column 210 (time axis), and the like. In addition, although not shown, the EPG201 is provided with a date switching label, a page switching button by color ("blue" button, "red" button, "green" button, "yellow" button) and Current date and time display bar, etc. The display column specified by the channel and time period is a program column, also called a program unit.

In this example, since the time period set in the fully automatic recording reservation table 67a is 19:00 to 22:00, the range of the frame 220 of the EPG 200 becomes a fully automatic recording object, and all programs in this time period are Recording.

Among them, the broadcast time of the programs in the program columns 221 to 223 spans a period of time. In the original full-automatic recording, the beginning and / or end of the program will not be recorded, resulting in the program being cut off, but in this embodiment In the middle, the reservation control unit 59 automatically sets the auxiliary reservation table 67b, thereby preventing the occurrence of plucking.

In addition, the EPG200 selects and operates the desired program column in the above program column through the remote controller 71 to display the next menu. Therefore, viewing or recording reservation can be performed by viewing or recording reservation from this menu (individual recording reservation ) The show.

Here, the setting of fully automatic recording will be described with reference to FIGS. 6 and 7. FIG. 6 is a schematic diagram of a time-shift machine recording setting screen 90. FIG. 7 is a schematic diagram of the threshold setting menu screen linked to the time-shift recording setting screen 90. As shown in FIG. 6, the time-shift machine recording setting screen 90 has a week row from Sunday to Saturday in the horizontal direction, and a time row of 0 hours to 23 hours in the vertical direction. When the user uses the remote control 71 to select the table where the week column and the time row intersect, the fully automatic recording time period can be specified for a specific day of each week (for example, Monday of each week), or different days within a week Specify the time period for fully automatic recording or not, and this time period is the reserved time period.

In the lower part of the screen, a setting button 93 for recording threshold value and a setting end button 94 are provided. The recording threshold setting button 93 is a button for setting a threshold time (threshold time: M) for allowing the user to record, and the button 93 is selected and operated to display the threshold setting menu screen 96 of FIG. 7.

The setting end button 94 is a button for saving the current setting and ending the setting screen. A slide bar 95 is provided at the right end of the screen. By sliding the slide bar 95, a part of the screen that exceeds the time line can be displayed.

In this example, the user uses the remote control 71 to set the recording start time from 19:00 from Sunday to Saturday, and the recording end time from 22:00. Here, the same time is set for all days of the week, but it is also possible to set the recording start time and the recording end time for a specific day in each week.

In addition, the time period 92 (frame of the grid) for one hour from 1:00 is the system maintenance time. This is the time to perform sorting and maintenance of recorded programs or automatically deleted programs, and then build them so that they can be released. The system maintenance time can be changed by the user from other menu screens.

FIG. 7 is a threshold setting menu screen 96 linked to the recording threshold setting button 93. When the recording threshold setting button 93 is pressed in the time-shifting recording setting screen 90 described above, the threshold setting menu screen 96 is displayed. The threshold setting menu screen 96 is displayed by the reservation control unit 59. The threshold setting menu screen 96 is a screen for the user to select and set a desired "threshold time".

On this threshold setting menu screen 96, several setting items for the user to select and specify the allowable value of the recording time, that is, the threshold time, and radio buttons 97 for specifying desired setting items from these setting items are displayed , And the setting end button 98 provided in the lowermost layer.

The radio button 97 designated by the user may specify a desired "threshold time", and the radio button 97 of a color change is designated. In this example, "2. Within 30 minutes before and after (fixed)" is set. The set value of the threshold time is stored in the storage device 67. The set value of the threshold time is a condition when the reservation control unit 59 reads out and generates auxiliary recording reservation information.

The setting items "1." to "3." can set the threshold within (fixed) each M minutes before and after. The setting item "1." specifies M minutes within 10 minutes before and after designation, the setting item "2." specifies M minutes within 30 minutes before and after designation, and the setting item "3." specifies M minutes within 60 minutes before and after designation. By specifying any of these setting items, the recording of the channel (program) is performed within M minutes from the recording start time when the automatic recording is reserved. In addition, the recording of the channel (program) is extended from the end of the recording to within M minutes. That is, by specifying any of these setting items, the recording of the channel (program) can be performed from within M minutes before the scheduled recording start time to within M minutes after the scheduled recording end time.

The setting items "4." to "6." can set the threshold of "total M minutes before and after", as long as the recording time can be traced back from the recording start time and the recording time can be extended from the recording end time If the sum of is within M minutes, then record. The setting item "7." can set the threshold of "set according to the duration of each program", and determine the time of retrospective recording (for example, half of the duration of the program) according to the duration of the program that crosses the recording start time. Similarly, it is decided to extend the recording time according to the length of the program that spans the end of recording.

The setting item "8." can set the threshold of "setting according to the length of the recording time period". (For example, if it is a 3-hour period, it will be 30 minutes, if it is a 5-hour period, it will be 50 minutes).

The setting item “9.” can set the threshold of “user setting”, and the user can freely set the threshold time.

The setting item “10.” does not set the threshold time as the allowable duration, that is, specifies “no threshold”. When the user does not specify the allowable duration, the initial value is set to "no threshold" of the setting item "10."

The setting end button 98 is a button for saving the current setting, ending the setting screen, and then returning to the previous screen.

In this example, the radio button 97 is used for selection. However, in addition to this, for example, a pull-down menu or other selection method may be used.

The recording operation of the recording and playback device 1 will be described below with reference to the flowchart of FIG. 8. In this recording and playback device 1, the recording and playback processing unit 56 reads in the recording reservation information of the fully automatic recording reservation table 67a and the auxiliary reservation table 67b of the storage device 67 at the time of start-up or every predetermined time (for example, 10-minute interval) (FIG. Step S101 of 8).

In addition, the program information acquisition unit 57 acquires EPG information (step S102).

The reservation control unit 59 extracts the broadcast information of the program (start time and end time of the program) from the acquired EPG information, and confirms whether there is a recording start time and / or a recording end that broadcasts the time period of the fully automatic recording reservation information read in The program at the time (step S103).

As a result of this confirmation, if there is a program that broadcasts the recording start time and / or recording end time across the time period, a broadcast start and / or end that corrects the scheduled recording start time and / or end time to the program is generated The auxiliary recording reservation information at the time (step S104) is stored in the auxiliary reservation table 67b.

Then, when the recording start time of the recording reservation information such as the fully automatic recording reservation table 67a and the auxiliary reservation table 67b is reached, the recording and playback processing unit 56 performs recording of the program of the channel. That is, the recording and playback processing unit 56 performs recording based on the recording reservation information (step S105). At this time, the programs reserved in advance for recording are recorded in the storage devices 6 and 7, and the attribute information of each program is stored in the recording information table 67c of the storage device 67.

When the recording ends, the program determination unit 60 reads the attribute information of the program of the storage device 67 and the condition that the program is not established from the storage device 67, and compares it with the attribute information of the recorded program to determine whether the recorded program satisfies the program The unsatisfied condition (step S106). In addition, this determination operation can also be performed all the time during recording.

As a result of the determination, when the condition that the program is not satisfied is not satisfied (NO in step S106), the program determination unit 60 records the establishment flag of the program ID of the program in the recording information table 67c as "0" (step S107) ).

In addition, as a result of the determination, when the condition that the program is not satisfied is satisfied (YES in step S106), the program determination unit 60 records the establishment flag of the program ID of the program in the recording information table 67c as "1" (step S108).

Hereinafter, the operation of the user when viewing the content (recorded program) recorded by the recording and playback device 1 will be described with reference to FIGS. 9 and 10. 9 is a display example of a time-shift machine history program table (program table of recorded programs: time-shift machine history program table) corresponding to the program table data (time-shift machine history program table data) generated by the program table generation unit 58 10 is a flowchart showing the operation of generating and displaying the time-shift machine history program table.

When the user watches the recorded program, the user operates the remote controller 71 to execute an instruction to display the time-shift machine history program table 301 (refer to FIG. 9) (step S110 in FIG. 10).

In the recording and playback device 1, when receiving an instruction from the remote controller 71 (YES in step S111), the program table generation unit 58 refers to the recording information table 67c, generates a selection screen of a fully automatic recording program, and immediately transfers the history of the machine The data of the program table (step S112) is then output to the display 26 via the OSD processing section 24 and the display control section 25 (step S113).

As a result, the time-shift machine history program table 301 (see FIG. 9) is displayed on the display 26.

As shown in FIG. 9, the time-shift machine history program table 301 is a table for displaying recorded programs in the form of cells on the vertical axis (channel) and horizontal axis (time), and has more than one program column. The time-shift machine history program table 301 displays the program column of the past recorded programs in substantially the same manner as the EPG 200 shown in FIG. 3.

In the time-shift machine history program table 301, it is possible to select a desired program column from a plurality of program columns by the remote controller 71, and then play and watch the recorded program.

Here, with reference to FIGS. 11 and 12, a display method for a case where there is a program whose content is not established among the recorded programs will be described. In the recording and playback device 1, the program table generation unit 58 refers to the recording information table 67c when generating the program column of the reproducible recorded program, and the program flag of the program whose establishment flag meets the unsatisfied condition in the program column is "1" On the program column 302, time-shift machine history program table data to which a mark 303 (see FIG. 11) indicating that the program is not established as content is added. That is, when creating the program column of the recordable program that can be played, the program table generation unit 58 adds a mark 303 (see FIG. 11) indicating that the content of the program is not established in the program column 302 of the program that satisfies the condition.

In the time-shift machine history program table displayed on the screen of the display 26, as shown in FIG. 11, a mark 303 is displayed in the program column 302 of a program that satisfies the unsatisfied condition, and when the user sees the mark 303, it can be judged at a glance This program is a program whose content is not established.

In addition, in this example, when a part of the program cannot be recorded, a triangular mark 303 is displayed in the program column 302. In addition, for example, when any one program is interrupted due to external reasons, such as As shown in FIG. 12, a text message 305 such as "<(!) Time-shift recording failed.>" May also be added and displayed on the program column 304. As a result, in the time-shift machine history program table 301, the program column corresponding to the completely unrecordable program will not become blank (missing), and the completely unrecordable program can be recognized as other unestablished programs, and the user can know Failed to record in the specified recording time period.

In the above embodiment, although the operation when "10. No threshold setting" is set in the threshold setting menu screen 96 shown in FIG. 7 is described, the following is shown in FIG. 7 with reference to FIGS. 13 to 16 The operation when each setting item is set on the threshold setting menu screen 96 of FIG.

First, referring to the flowchart of FIG. 13, when the radio button 97 in the threshold setting menu screen 96 of FIG. 7 is set to the setting item “2.” within 30 minutes before and after each (fixed) ” The operation will be described. In addition, the operation in the case of setting items "1." and "3." is different depending on whether the threshold time M is 10 minutes or 60 minutes. Therefore, it is only necessary to re-read the threshold time from the description of the setting item "2." M is sufficient, and the explanation of the setting items "1." and "3." is omitted.

In this recording and playback device 1, when the threshold value (permissible condition) of the setting item "2." is set, the reservation control unit 59 selects from the fully automatic setting in the fully automatic recording reservation table 67a of FIG. The recording time (recording start time, recording end time) and the broadcast information of the program extracted from the EPG information determine whether there is a program broadcast across the fully automatic recording time (step S211 in FIG. 13). Among them, the program broadcast across the fully automatic recording time may refer to the time when the broadcast starts and / or the time when the broadcast ends is not from the scheduled automatic recording start time to the automatic recording end time.

As a result of this determination, if there is a program broadcast across the fully automatic recording time, the reservation control unit 59 reads out the preset threshold time M from the storage device 67 (step S212).

Next, the reservation control unit 59 determines whether the time of program broadcasting is before the recording start time (step S213).

When the program broadcast time is before the recording start time (YES in step S213), the reservation control unit 59 determines whether the interval between the program broadcast time and the recording start time is within the threshold time M (step S214).

As a result of this determination, when the interval between the broadcast time of the program and the recording start time is within the threshold time M (YES in step S214), the reservation control unit 59 generates auxiliary recording reservation information to start recording of the program The time is the broadcast start time of the program, and the auxiliary recording reservation information is registered in the auxiliary reservation table 67b (step S215).

In addition, as a result of the determination, when the interval between the time of the program broadcast and the recording start time exceeds the threshold time M (“No” in step S214), the reservation control unit 59 keeps the reservation recording information unchanged, in the recording information table The recording information of the program is recorded in 67c, and a flag "1" indicating that the program is not established is set in the column of the establishment flag (step S216).

On the other hand, as a result of the determination in step 213, when the program broadcast end time is after the recording end time ("No" in step S213, "Yes" in step S217), the reservation control unit 59 determines the time when the program broadcast ends Whether the interval length from the recording end time is within the threshold time M (step S218).

As a result of this determination, when the interval between the time when the program broadcast ends and the time when the recording ends is within the threshold time M (YES in step S218), the reservation control unit 59 generates auxiliary recording reservation information so that the program ’s The recording end time is the broadcast end time of the program, and the auxiliary recording reservation information is registered in the auxiliary reservation table 67b (step S219).

The above procedure is performed on the programs of all channels, and when all channels are checked (YES in step S220), the process ends.

Next, with reference to the flowchart of FIG. 14, the operation when the setting item “4. Total within 20 minutes before and after” is selected on the threshold value setting menu screen 96 of FIG. 7 will be described. In addition, the operation in the case of setting items “5.” and “6.” differs depending on whether the threshold time M is 30 minutes or 60 minutes. Therefore, as long as the threshold time M is re-read from the description of the setting item “4.” That is, the description of the setting items "5." and "6." is omitted.

In this recording and playback device 1, when the threshold value (permissible condition) of the setting item "4." is set, the reservation control unit 59 selects from the fully automatic setting in the fully automatic recording reservation table 67a of FIG. The recording time (recording start time, recording end time) and the broadcast information of the program extracted from the EPG information determine whether there is a program broadcast across the fully automatic recording time (step S230).

As a result of this determination, if there is a program broadcast across the fully automatic recording time, the reservation control unit 59 reads the preset threshold time M from the storage device 67, and at the same time, sets it in a memory such as RAM54 The remaining time R of the counter is reset, that is, set to "0" (step S231).

Next, the reservation control unit 59 determines whether the program starts broadcasting before the recording start time (step S232).

As a result of this determination, if the time when the program starts broadcasting is not before the recording start time or if the program has not started before the recording start time ("No" in step S232), the reservation control unit 59 sets a threshold for the remaining time R Time M, that is, the reservation control unit 59 sets the remaining time R as the threshold time M, R = M (step S233).

In addition, as a result of the determination in step S232, if the program starts before the recording start time (YES in step S232), then, the reservation control unit 59 determines whether the interval between the time when the program starts broadcasting and the recording start time is within Within the threshold time M. That is, it is determined whether or not the program starts within M minutes from the recording start time (step S234).

As a result of this determination, if the interval between the time when the program starts broadcasting and the recording start time is not within the threshold time M, that is, if the program does not start within M minutes ("No" in step S234), the reservation control unit 59 A new record of the program ID is generated in the recording information table 67c of the program, and a flag "1" indicating that the program is not established is set therein (step S235).

In addition, as a result of the determination in step S234, if the interval between the time when the program starts broadcasting and the recording start time is within the threshold time M, that is, when the program starts within M minutes (YES in step S234), the reservation control The unit 59 generates auxiliary recording reservation information so that the recording start time of the program is the broadcast start time of the program, and registers the auxiliary recording reservation information in the auxiliary reservation table 67b. In addition, the remaining time R of the threshold time M of the threshold time M- (recording start time-broadcast start time of the program) is added (set) to the counter (step S236). That is, the counter is set to the remaining time R, where the remaining time R = threshold time M- (recording start time-broadcast start time of the program).

Then, the reservation control unit 59 confirms the remaining time R set in the counter (step S237). By this confirmation, in the case where the remaining time R is not "0" (NO in step S237), that is, if there is a balance in the remaining time R, next, the reservation control unit 59 determines the broadcasting of the program after the recording end time Whether to end (step S238).

As a result of this determination, when the broadcast of the program ends after the recording end time (YES in step S238), the reservation control unit 59 determines whether the interval between the broadcast end time of the program and the recording end time is within the remaining time R Within minutes. That is, it is determined whether the program ends within the remaining time R minutes later than the recording end time (step S239).

As a result of this determination, if the interval between the time when the program broadcast ends and the recording end time is within the remaining time R minutes, that is, when the program ends within the remaining time R minutes (YES in step S239), the reservation control The unit 59 generates auxiliary recording reservation information so that the recording end time of the program is the broadcast end time of the program, and registers the auxiliary recording reservation information in the auxiliary reservation table 67b (step S240).

As a result of the determination in step S239, if the interval between the time when the program broadcast ends and the time when the recording ends is not within the remaining time R minutes, that is, if the program does not end within the remaining time R minutes (No in step S239) The reservation control unit 59 generates a new record of the program ID in the recording information table 67c of the program, and sets a flag "1" indicating that the program is not established therein (step S241).

The above procedure is performed on the programs of all channels, and when all channels are checked (YES in step S242), the process ends.

With reference to the flowchart of FIG. 15, the operation in the case where the setting item “7. Set for each program duration” on the threshold setting menu screen 96 of FIG. 7 will be described.

In this recording and playback device 1, when the setting item "7." is set, the reservation control unit 59 starts from the fully automatic recording time (recording start time) set in the fully automatic recording reservation table 67a of FIG. 2 , Recording end time) and the broadcast information of the program extracted from the EPG information, it is determined whether there is a program broadcast across the fully automatic recording time (step S250).

As a result of this determination, if there is a program broadcast across the fully automatic recording time (YES in step S250), the reservation control unit 59 subtracts the broadcast from the broadcast end time of the program included in the broadcast information of the program Calculate the duration L (broadcast time, unit is hour or minute) of the program at the start time, and set the half time (L / 2) of the calculated duration L of the program to be traced back from the recording start time to The allowable length of time to start recording, that is, the threshold time M dating back to the start time of program broadcasting (step S251). Next, the reservation control unit 59 determines whether the program broadcasted across the recording start time starts broadcasting before the recording start time based on the fully automatic recording time (recording start time, recording end time) and the broadcast information of the program extracted from the EPG information (Step S252).

As a result of this determination, when the broadcast of the program starts before the recording start time (YES in step S252), the reservation control unit 59 determines whether the interval between the time when the program broadcast starts and the recording start time is within the threshold time M Within. That is, it is determined whether or not the program has been traced back from the recording start time and within a threshold time M of 1/2 of the duration L of the program (step S253).

As a result of the determination, if the interval between the time when the program broadcast starts and the time when the recording starts exceeds the threshold time M, that is, if the program does not start within the threshold time M minutes (NO in step S253), the reservation control unit 59 Leave the reservation recording information as it is (without generating auxiliary recording reservation information), record the recording information of the program in the recording information table 67c, and set the flag "1" indicating that the program is not established in the column of the establishment flag (step S254 ). Recording the recording information of the program means that a new record of the program ID is generated in the recording information table 67c of the program, and a flag "1" indicating that the program is not established is set therein.

In addition, as a result of the determination in step S253, if the interval between the time when the program broadcast starts and the recording start time is within the threshold time M, that is, when the program starts within the threshold time M minutes (YES in step S253), The reservation control unit 59 generates auxiliary recording reservation information so that the recording start time of the program is the broadcast start time of the program, and registers the auxiliary recording reservation information in the auxiliary reservation table 67b (step S255).

On the other hand, as a result of the determination in the above-mentioned determination step S252, if the broadcast of the program across the recording time has not started before the recording start time (NO in step S252), then, the reservation control unit 59 confirms Whether the program ends after the recording end time (step S256).

As a result of this confirmation, when the program broadcast ends after the recording end time (YES in step S256), the reservation control unit 59 determines whether the interval between the broadcast end time of the program and the recording end time is within the threshold of L / 2 Within time M minutes (step S257).

As a result of this determination, when the interval between the broadcast end time of the program and the recording end time is within the threshold time M (YES in step S257), the reservation control unit 59 generates auxiliary recording reservation information so that the program The recording end time of is the broadcast end time of the program, and the auxiliary recording reservation information is registered in the auxiliary reservation table 67b (step S258).

In addition, as a result of the determination in step S257, if the interval between the end time of the broadcast of the program and the end time of the recording exceeds the threshold time M minutes, that is, if the program broadcast does not end within the threshold time M (NO in step S257) ), The reservation control unit 59 sets the flag in the above step S254 without generating auxiliary recording reservation information.

Then, when the programs spanning the recording time are checked for the programs of all channels (YES in step S259), the process ends.

Here, specific examples of retrospective recording or extended recording will be described. For example, if the program is a 2 hour program (L = 120 minutes), the threshold time M = 120 (L) × (1/2) = 60 minutes becomes the object of retrospective recording or extended recording. In addition, when the threshold time M is exceeded, recording is performed as in the past, and the recording time is not tracked.

In this case, in the EPG 200 of FIG. 3, the start time of the program 221 of "Variety A" is PM6: 50, the program duration L is 70 minutes, and M = 70 * (1/2) = 35 minutes, because Within the range of "threshold value", in the recording and playback device 1 of the present embodiment, the beginning can be prevented from being cut off.

In addition, in the EPG 200 of FIG. 3, the end time of the program 222 of "Movie B" is PM 10:30, the duration of the program L is 150 minutes, and M = 150 * (1/2) = 75 minutes, because the "threshold" Within the scope of the present invention, in the recording and playback device 1 of the present embodiment, the ending can be prevented from being cut off.

Similarly, in the EPG 200 of FIG. 3, the broadcast start time of the program 223 of the "special program C" is PM6: 30, the broadcast end time is PM11: 00, the duration of the program L is 270 minutes, and M = 270 × (1 / 2) = 135 minutes, because it is within the range of the "threshold value", so in the recording and playback apparatus 1 of the present embodiment, it is possible to prevent being scratched.

Next, the operation when the setting item “8. Setting according to the recording time period duration” is selected on the threshold value setting menu screen 96 of FIG. 7 will be described with reference to the flowchart of FIG. 16.

In this recording and playback device 1, when the setting item "8." is set, the reservation control unit 59 starts from the fully automatic recording time (recording start time) set in the fully automatic recording reservation table 67a of FIG. 2 , Recording end time) and the broadcast information of the program extracted from the EPG information, it is determined whether there is a program broadcast across the fully automatic recording time (step S260).

As a result of this determination, if there is a program broadcast across the fully automatic recording time, the reservation control unit 59 subtracts the recording start time from the recording end time in order to set according to the length of the recording time period, and multiplies the value by 1/6 , The threshold time M is calculated. At the same time, the remaining time R of the counter set in the memory is reset, that is, set to "0" (step S261).

For example, when the recording start time is 19:00 and the recording end time is 10:00, the recording start time minus the recording end time is 3 hours. If it is multiplied by 1/6, it is 1/2 hour. , That is, 30 minutes, set it as the threshold time M, that is, the threshold time M is 30 minutes.

Next, the reservation control unit 59 determines whether the program starts broadcasting before the recording start time (step S262).

As a result of this determination, if the program does not start broadcasting before the recording start time (NO in step S262), the reservation control section 59 sets the remaining time R to the threshold time M, that is, R = M (step S263).

In addition, as a result of the determination in step S262 described above, if the program starts broadcasting before the recording start time (YES in step S262), then the reservation control unit 59 determines whether the interval between the broadcast start time of the program and the recording start time is within the threshold Within M minutes. That is, it is determined whether the program starts within M minutes from the recording start time (step S264), or it is determined whether the program starts within M minutes from the recording start time (step S264).

As a result of this determination, if the interval between the broadcast start time of the program and the recording start time is not within the threshold time M, that is, when the program does not start within M minutes from the recording start time, or, in If the program does not go back within M minutes from the recording start time (NO in step S264), the reservation control unit 59 generates a new record of the program ID in the recording information table 67c of the program, and A flag "1" indicating that the program is not established is set therein (step S265).

In addition, as a result of the determination in step S264, if the interval between the broadcast start time of the program and the recording start time is within the threshold time M, that is, when the program start is traced back within M minutes from the recording start time, or When the program starts back within M minutes from the recording start time (YES in step S264), the reservation control unit 59 generates auxiliary recording reservation information so that the recording start time of the program is the broadcast start time of the program, And the auxiliary recording reservation information is registered in the auxiliary reservation table 67b. In addition, the remaining time R of the threshold time M of the threshold time M- (recording start time-broadcast start time of the program) is added (set) to the counter (step S266).

Then, the reservation control unit 59 confirms the remaining time R set in the counter (step S267). By this confirmation, in the case where the remaining time R is not "0" (NO in step S267), that is, if there is a balance in the remaining time R, next, the reservation control section 59 determines the broadcast of the program after the recording end time Whether it ends. That is, it is determined whether the program ends after the recording end time (step S268).

As a result of this determination, if the broadcast of the program ends after the recording end time (YES in step S268), that is, if the broadcast of the program ends after the recording end time, the reservation control section 59 determines that the broadcast of the program ends Whether the interval between the time and the recording end time is within the remaining time R. That is, it is determined whether the program ends within the remaining time R minutes later than the recording end time (step S269).

As a result of the determination, if the interval between the time when the broadcast of the program ends and the time when the recording ends is within the remaining time R minutes, that is, if the program ends within the remaining time R (YES in step S269), the reservation control The section 59 generates auxiliary recording reservation information so that the recording end time of the program is the broadcast end time of the program, and registers the auxiliary recording reservation information in the auxiliary reservation table 67b (step S270).

In addition, as a result of the determination in step S269, when the interval between the broadcast end time of the program and the recording end time is not within the remaining time R minutes, when the time from the recording end time to the broadcast end time of the program exceeds the remaining time R (step (No in S269), the reservation control unit 59 does not generate auxiliary recording reservation information, generates a new record of the program ID in the recording information table 67c of the program, and sets a flag "1" indicating that the program is not established therein (Step S271).

The above procedure is performed on the programs of all channels, and when all channels are checked (YES in step S272), the process ends.

As described above, according to this recording and playback device 1, it is started before the recording start time specified in full automatic recording in advance.

In addition, according to the present embodiment, the predetermined traceback time and / or extended time is used as the “threshold time M” to determine whether it is possible to trace the preset recording start time of the target program for recording or to extend the preset recording end The recording is performed at all times, so it will not be recorded at a time that greatly deviates from the time period set by the user for full-automatic recording, and thus will not cause defects such as compression of the capacity of a recording medium such as an HDD.

Furthermore, according to the present embodiment, the threshold time M is obtained by using the program duration L and the recording period duration of the target program as the calculation reference value, and the program converging within M minutes is tracked for recording, so it is not brought to the user Unnecessary trouble, can retrospectively record or extend the recording of the program recorded slightly beyond the time period. Therefore, by setting the allowable duration (threshold time M), retrospective recording or extended recording of the program that spans the recording start time and the recording end time set by the user in the fully automatic recording function can eliminate significant deviations from the user setting. Record the program at the start time and the end time of the recording, and can remedy the program that is slightly scratched.

In addition, by setting the threshold time M in advance, for programs exceeding the threshold time M, since retrospective recording or extended recording is not performed, it may sometimes be recorded as a program whose content is not established, and may not be recorded due to the influence of radio wave failure. In the case where a program or a program that was accidentally operated during recording is recorded as a program whose content is not established, when there is an instruction operation to play a recorded program, the program table generation unit 58 generates information based on the attribute information and recording information of the program The establishment flag of the table 67c, in the program column 302 of the program that satisfies the condition in the program column of the recorded program (as a program whose content is not established), a time-shift history program table 301 to which the mark 303 indicating that the program is not established is added and displayed , So the user can only grasp the program column 302 of the time-shifted history program table 301, even without watching the program, can grasp the beginning and end of the program, lost in the program due to bad signal, part or all of the program failed Recorded programs (programs whose contents are not established).

In addition, in the above-mentioned embodiment, the example in which the triangular mark 303 is added to the lower right corner of the program column 302 is shown. In addition, for example, the cause of the content may not be established according to the program (user operation or recording setting) To change the display mode of the mark 303 (change the position of the mark 303, gray out the program name or program information, or change the color of the mark 303, etc.).

For example, in the case where the cause of the program is not established is the inconsistency of the time set for the recording, and the end of the title is lost due to the inconsistency of the recording end time, a mark 303 can be added to the right corner of the program column 302, resulting in the intro In case of loss, a mark 303 may be added in the left corner of the program column 302. In addition, a mark 303 may be added to the left and right corners of the program column 302 of the program determined to be unsuccessful due to the loss of any one of the opening or ending.
