Description

Embodiments of the present invention relate to electronic devices and program recording methods.

In recent years, a recorder having a so-called full recording function (also called a round recording function or a time-shift machine recording function) that automatically records a program by designating one or more channels and a recording time zone in advance. (Hereinafter referred to as "all recorders") is becoming widespread.

Since this all recorder records the entire program in the channel and time zone specified by the user, the user does not have to select and reserve a program one by one from the program guide, and also goes back to the past and selects a program from the past program guide. It is a highly convenient function for users, such as being able to watch.

However, in all conventional recorders, recording starts and ends all at once for each channel based on the time zone (start time, end time) set by the user, so this time zone (recording start time or recording end time). There is a problem that a program that is broadcast over the same time is recorded without the beginning or the end of the program, and when the user watches the program later, a situation may occur in which the program is partially not seen.

For example, if the recording start time is set to 21:00 in the time-shift machine function recording setting, the program starting at 20:50 will be cut off, and this is a program composed of Kishōtenketsu such as a drama. If there is, the "ki" part cannot be seen, and the background of the drama cannot be understood, resulting in dissatisfaction. Also, if the user sets the recording end time at 22:00 when setting the recording for the time zone, the program ending at 22:10 will be cut off, and the "conclusion" part will not be seen, and the important ending will be. The result is unclear and dissatisfied.

An object to be solved by the present invention is to provide an electronic device and a program recording method capable of preventing the start and / or end of a program whose broadcast overlaps with the recording start time and / or the recording end time of time zone recording. There is something in it.

The storage device 67 has a complete recording reservation table 67a (see FIG. 2) for scheduled recording by the complete recording function, an auxiliary recording reservation table 67b (see FIG. 4), and recording information which is attribute information of the recorded program. A table 67c (see FIG. 5) and the like are stored.

The complete recording reservation table 67a is a first recording reservation information in which recording reservation information (first recording reservation information) for batch reservation recording of programs broadcast on a plurality of channels by designating a time zone is stored. Functions as a storage unit. The auxiliary recording reservation table 67b is a second recording reservation storage unit that stores auxiliary recording reservation information, which is second recording reservation information for assisting the start / end of reserved recording with respect to the recording reservation information of the complete recording reservation table 67a. Functions as.

The information in these tables is set based on the broadcast information of the program extracted from the EPG data acquired by the program information acquisition unit 57. The reservation control unit 59, which will be described later, is in charge of registering / deleting the recording reservation information (the reservation control unit 59 registers / deletes the recording reservation information).

As shown in FIG. 2, a time zone designated by the time machine recording setting screen 90 of FIG. 6 is set in the complete recording reservation table 67a. In this example, the recording start time is set to 19:00 and the recording end time is set to 22:00, and in the EGP201 of FIG. 3, 7:00 pm (beginning of the time zone of “PM7” in FIG. 6) to 10:00 pm (FIG. The period (the end of the time zone of "PM9" in 6) is the time zone for all recordings.

As shown in FIG. 4, the auxiliary reservation table 67b stores the recording reservation information of the program whose broadcast time spans the time zone designated by the complete recording reservation table 67a.

In this example, the broadcast of the program "Variety A" with the program ID "30022" straddles the recording start time "19:00" among all the recording time zones reserved for recording on the recording date "2018/9/4". Therefore, a retroactive recording reservation is set so that the recording start time of the channel is earlier than the broadcast start time "18:50" of the program "Variety A". In this auxiliary reservation table 67b, the broadcast end time of the program "Variety A" is set to "-" without setting because it does not straddle the recording end time of the entire recording time zone. If there is no setting "-", the time zone of the full recording reservation table 67a is prioritized for recording, so for this channel, recording is performed from the broadcast start time "18:50" to the recording end time "22:00". Will be done.

In addition, the broadcast of the program "Movie B" with the program ID "30043" is broadcast at the recording end time "22:00" among all the recording time zones reserved for recording on the recording date "2018/9/4". Since the end time is "22:30", the reservation for extended recording is set so that the recording end time of the channel is delayed to "22:30" and the recording is ended. In this auxiliary reservation table 67b, the broadcast start time of the program "movie B" is set to "-" without setting because it does not straddle the recording start time of the entire recording time zone. If there is no setting "-", the time zone of the recording reservation table 67a is prioritized for recording, so for this channel, recording is performed from the broadcast start time "19:00" to the recording end time "22:30". Will be done.

Further, among all the recording time zones reserved for recording on the recording date "2018/9/4", the program "30062" with the program ID "30062" is set at the recording start time "19:00" and the recording end time "22:00". Since the broadcasts of "Special Number C" straddle each other, the recording start time of the channel is set earlier than the broadcast start time "18:30" of the program "Special Number C", and the reservation for retroactive recording is set, and the recording end time is set to the program "Special Number C". The reservation for extended recording is set to be delayed to the broadcast end time "23:00".

In addition, the storage device 67 also holds (stores) a recording reservation table (not shown) for individual program reservation recording in which the user specifies a channel (or program name) and a date and time to record in program units. Will be done. The recording reservation information includes a program ID, a title, a channel, a recording format, a recording time zone (recording start time, recording end time), and the like.

As shown in FIG. 5, the recording information table 67c stores attribute information related to the recorded content of the program actually recorded in the storage devices 6 and 7.

In this example, the title of the program, the recording date, the broadcast time of the program on the EPG (broadcast start time, broadcast end time), and the recording time of all recorded programs (recording start time, recording end time) correspond to the program ID. ), The establishment flag, etc. are stored. In addition, the recording information table 67c also stores channels, recording formats, text data in program columns, and the like.

Further, the storage device 67 stores in advance the condition that the program is not established (incomplete) as the content. As an example of the condition, for example, the actual time zone (recording start time, recording end time) in which the program was actually recorded and the broadcast time zone (broadcast start time, broadcast) of the program on the electronic program table for which the program was reserved for recording are used. If there is a discrepancy with the end time), or if the discrepancy time difference is greater than or equal to the permissible value (when there is a time lag between the recording start time and recording end time for a certain period of time or more). be.

Other conditions include, for example, when a program contains an unrecorded part due to radio interference during broadcasting, or when there is a user operation that affects recording during recording of the program. be. User operations that affect recording include, for example, when the time-shift machine recording setting is switched from "use" to "not use" in the middle of a program, and vice versa, or during recording, the recording mode is set. When you change it, etc.

There are also conditions for hardware problems. For example, when the B-CAS card is not inserted, when the antenna is not connected, when reception is poor, recording prohibited programs are recorded, or when some of the uncontracted programs of pay broadcasting are recorded in a playable state. , One of the conditions is also included.

Further, the storage device 67 holds information that can be rewritten from the outside, such as contract information of a pay channel, update information referred to by the CPU 52 (main control block 51), an update program corresponding to the update information, or copy control information. do. The storage device 67 may be, for example, in the shape of a card or in any portable shape, and may be attached / detachable from a card slot provided in the recording / reproducing device 1.

It will be available for viewing. The attachment / detachment of the storage medium is detected by the main control block 51.

In the work area provided by the RAM 54, the main control block 51 executes processing corresponding to the input signal and the control signal according to the control of the CPU 52 based on the control program held by the ROM 53.

The CPU 52 (main control block 51) acquires the recording / playback processing unit 56 and program information based on the operation information (control input) from the operation unit 61 and the operation information (control input) from the remote controller 71 received by the reception unit 62. It controls the unit 57, the program guide generation unit 58, and the reservation control unit 59. The CPU 52 also writes various setting information and management information about other recorders and television devices connected to the home server in the home network to the NVM 55.

The CPU 52 controls the recording / playback processing unit 56 based on, for example, an operation instruction (control input) by the user or recording reservation information for scheduled recording, and outputs a video signal, an audio signal, or the like output by the video decoder 22 and the audio decoder 32. , Record (record) in the storage devices 6 and 7 on the side designated in advance.

The CPU 52 controls the program information acquisition unit 57 according to the program or application held by the NVM 55 or the ROM 53 or the firmware of the CPU 52, and acquires various information (attribute information) related to the program.

The program information acquisition unit 57, for example, can be viewed as attribute information of a program from PSI (Program Specific Information) or SI (Service Information) among the control information attached to the TS separated by the signal processing unit (TS separation unit) 12. Acquires age-restricted age information, EPG (Electronic Program Guide) information, rebroadcast programs, and so on. The EPG (Electronic Program Guide) information includes a program broadcast start time, a broadcast end time, a program title, a program content, a performer name, and the like.

Further, the program information acquisition unit 57 acquires program information (broadcast schedule) for, for example, 8 days for programs of all channels (broadcasting stations) that can be received by the input unit 11, and for example, RAM 54, NVM 55, or a storage device 67. Remember in.

When recording a video signal, an audio signal, or the like in the storage devices 6 or 7, the recording / reproduction processing unit 56 encrypts the video signal, the audio signal, or the like and converts the video signal, the audio signal, or the like into a predetermined recording format. The recording / playback processing unit 56 reads and decodes a desired video signal, audio signal, or the like from the storage devices 6 and 7 in response to an instruction input from the remote controller 71 or the like based on the user operation, and the video decoder 22 and the audio decoder 32. Output to.

The recording / playback processing unit 56 can record a program broadcast on a plurality of channels, and records the program based on the recording reservation information such as the complete recording reservation table 67a and the auxiliary reservation table 67b (hereinafter, “all recording”). It is called "recording" or "time-shift machine recording").

Specifically, the recording / playback processing unit 56 starts recording in any of the preset storage devices 6 and 7 at the recording start time with reference to the recording reservation information, and ends the recording at the end time. At the time of recording (recording), the recording / playback processing unit 56 stores attribute information (recorded information of the recorded program) related to the target program in the recording information table 67c of the storage device 67.

That is, the recording / playback processing unit 56 records and records (records) a program reserved in advance in the time zone and / or a program whose recording time is specified in the auxiliary reservation table 67b in the storage devices 6 and 7. It functions as a recording unit that stores attribute information for each program in the storage device 67. The storage device 67 functions as a program information storage unit in which program information, which is attribute information for each recorded program, is stored.

The attribute information is almost the same as the recording reservation information such as the program ID, title, channel, recording format, time zone (start time, end time), and is the EPG (electronic program guide) information acquired by the program information acquisition unit 57. The broadcast start time and broadcast end time, and the actual recording start time and recording end time of a part of the attribute information are recorded in the recording information table 67c (see FIG. 5) for each program ID. The contents of the recording information table 67c will be described later in the description of FIG.

The program guide generation unit 58 is an EPG (electronic) acquired by the program information acquisition unit 57 under the control of the CPU 52 when the user performs an EPG (electronic program guide) display operation when viewing a program or making a recording reservation. Based on the program guide) information, the program guide data (EPG data) for displaying the program guide displayed by the display 26 via the OSD processing unit 24 is generated. The generated program guide data (EPG data) is converted into a program guide display signal by the OSD processing unit 24, and is output by the display control unit 25.

Further, the program guide generation unit 58 has the attribute information of the recorded program acquired by the program information acquisition unit 57 and the recording information table 67c when the user performs a time shift machine past program guide display operation at the time of program playback or the like. Based on the recorded information (see FIG. 5), the program guide data (time shift machine past program guide data) for displaying the recorded program guide displayed by the display 26 via the OSD processing unit 24 is generated.

When the program guide generation unit 58 generates the program guide data, the program is placed in the program column of the program whose establishment flag of the recording information table 67c is "1", which satisfies the condition among the program columns included in the data. A mark (for example, a triangle mark, a code such as an extension mark, a character, etc.) indicating that the content is unsuccessful (incomplete) is added and displayed.

The OSD processing unit 24 converts the time-shift machine past program guide data into a program guide display signal, outputs the data to the display 26 through the display control unit 25, and displays the time-shift machine past program guide 301 (see FIG. 9) on the screen of the display 26. indicate.

The time shift machine past program guide data is a playable recorded program based on the recording information of the recording information table 67c in which the attribute information of the recorded program (the information of the program when the program is recorded) is held. One or more program columns 221, 222, 223 ...

It is a list for playing a recorded program having (see) and the like. The time-shift machine past program table 301 shown in FIG. 9 is an example of a display form in which the list is displayed in a table format with vertical and horizontal program columns. In the time-shift machine past program table 301, the programs that are out of the time zone recorded by the full recording recording are also normally recorded as shown by the frame line 310.

On the other hand, in this recording / playback device 1, although there are programs that are relieved by retroactively or extending the recording time, some programs that satisfy the condition of program failure and are not established as contents may be recorded.
In this case, as shown in FIG. 11, among the plurality of program columns, the program column 302 of the program satisfying the condition is provided with a mark 303 indicating that the program is not established as content.

The program determination unit 60 reads out the condition of program failure stored in the storage device 67, determines whether or not the recorded program satisfies the read condition, and sets the determination result flag to the corresponding program in the recording information table 67c. Record in the column of ID establishment flag. As a flag, "1" is recorded when the condition of program failure is satisfied, and "0" is recorded when the condition is not satisfied. The conditions may be set in advance in the program determination unit 60 without being stored in the storage device 67. In this case, the program determination unit 60 determines whether or not the program is unsuccessful (incomplete) as content by determining whether or not the recorded information of the recorded program satisfies a preset condition.

Under the control of the CPU 52, the reservation control unit 59 is instructed by the user of the individual program on the EPG (program guide) in which the EPG data generated by the program guide generation unit 58 is output to the display 26 via the OSD processing unit 24. Based on (operation input), the recording reservation for the reserved recording of the program is accepted, the recording reservation information is generated, and the recording reservation information is stored in the storage device 67.

In addition, the recording reservation information may be stored in the RAM 54 or the NVM 55.

The recording reservation information of the complete recording reservation table 67a is a time zone (recording start time, recording end time) in which the recording / reproduction processing unit 56 collectively records the programs of all channels. You can optionally choose not to record some channels. Further, although the recording reservation information of the complete recording reservation table 67a shows an example of a time zone using one pair of a start time and an end time, a plurality of tables may be prepared and a plurality of time zones may be set.

Further, the reservation control unit 59 sets the recording reservation information of the program that needs to be corrected in the time zone of the complete recording recording reservation (first recording reservation information) in the auxiliary reservation table 67b. In the auxiliary recording reservation table 67b, the auxiliary recording reservation information (second recording reservation) for correcting (assisting) the start / end of the reserved recording for each channel (each program) with respect to the full recording recording reservation (first recording reservation information). Information) is stored in the auxiliary reservation table 67b.

More specifically, the reservation control unit 59 will use the program broadcast information (program broadcast start time, broadcast end time) from the program data (EPG information) scheduled to be broadcast acquired by the program information acquisition unit 57 at the time of activation or at regular time intervals. ) Is extracted and compared with the recording start time and / or the recording end time in the time zone of the all-recording recording reservation, and the recording start time and / or the recording end of the reserved recording of the program that is broadcast over the time zone of the all-recording recording reservation. Auxiliary recording reservation information (second recording reservation information) corrected for the broadcast time of the program is generated, and the time is stored in the auxiliary recording reservation table 67b.

The reservation control unit 59 generates auxiliary recording reservation information in which the broadcast start time of the program starting before the recording start time in the time zone set in the complete recording reservation table 67a is set as the recording start time, and the auxiliary reservation table Set to 67b.

Further, the reservation control unit 59 generates auxiliary recording reservation information in which the broadcast end time of the program ending after the recording end time in the time zone set in the complete recording reservation table 67a is set as the recording end time, and the auxiliary reservation is made. Set in table 67b.

When the time of the difference between the recording time in the time zone of the complete recording reservation table 67a and the broadcast time of the program is within a preset allowable time (threshold time M), the reservation control unit 59 records all recordings. Auxiliary recording reservation information for correcting the reserved recording information (recording start time, recording end time) of the reservation table 67a is generated, and if the allowable time is exceeded, the auxiliary recording reservation information is not generated.

The recording / playback processing unit 56, the program information acquisition unit 57, the program table generation unit 58, the reservation control unit 59, and the program determination unit 60 are each, or at least one, or some of any number of the CPU 52 firmware. There may be.

On the screen displayed on the display 26, the CPU 52 has a color button display ([blue] button display, [red] button display, [green] button display, and [yellow] button display: illustrated. The operation input from the remote controller 71 corresponding to each of the above) is accepted. That is, the CPU 52 corresponds to the operation of any of the [blue] key 71B, the [red] key 71R, the [green] key 71G, and the [yellow] key 71Y of the remote controller 71, and the button of a specific color displayed on the screen. It is judged that the instruction is to be performed, and the instruction corresponding to the operation input of the key is received.

Here, two program guides (one for broadcast viewing and recording reservation and one for viewing a recorded program) generated by the program guide generation unit 58 will be described.
FIG. 3 shows a display example of an EPG (program guide of current and future broadcast programs: future program guide) corresponding to the program guide data (EPG information) generated by the program guide 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 (broadcasting stations), a time zone display column 210 (time axis), and the like. ing. In addition, although not shown, the EPG201 is provided with a date switching tab, a page switching button for each color ([blue] button, [red] button, [green] button, [yellow] button), and a current date / time display field. Has been done. The display column specified by the channel and time zone is the program column and is also called a program cell.

In this example, since the time zone set in the complete recording reservation table 67a is from 19:00 to 22:00, the range of the frame line 220 of the EPG200 is the entire recording target, and all the programs in that time zone are targeted for recording. It will be recorded.

Among them, the broadcast time of the program in the program column 221 to 223 straddles the time zone, and in the full recording as it is, the beginning and / or the end of the program is not recorded, which causes a head cut and a tail cut. However, in the present embodiment, the reservation control unit 59 automatically sets the auxiliary reservation table 67b to prevent the occurrence of head cuts and tail cuts.

In addition, the EPG 200 displays the next menu by selecting and operating a desired program field in the above program field with the remote controller 71. Therefore, the program can be viewed or recorded by operating the recording reservation from the menu. You can watch or schedule recording (individual recording reservation).

Here, the setting of full recording recording will be described with reference to FIGS. 6 and 7. FIG. 6 is a diagram showing an example of the time-shift machine recording setting screen 90, and FIG. 7 is a diagram showing a threshold value setting menu screen linked to the time-shift machine recording setting screen 90.
As shown in FIG. 6, the time-shift machine recording setting screen 90 is provided with a day column from Sunday to Saturday in the horizontal direction and a time line from 0 hour to 23 hours in the vertical direction. The user can specify the time zone for all recording recording for each day of the week by selecting the box where the day of the week column and the time row intersect with the remote controller 71.

At the bottom of the screen, a recording threshold setting button 93 and a setting end button 94 are provided. The recording threshold setting button 93 is a button for setting (designating) the threshold time (threshold time: M) that allows the user to record, and by selecting and operating this button 93, the threshold setting in FIG. 7 is performed. The menu screen 96 is displayed.

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, it is possible to display a portion of the time line that extends beyond the screen.

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

The time zone 92 (shaded frame) from 1:00 to 1 hour is the system maintenance time. This is the time to perform maintenance such as organizing recorded programs and automatically deleted programs and rebuilding them so that they can be distributed. The user can change the setting of this system maintenance time from other menu screens.

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

On the threshold setting menu screen 96, some setting items for the user to select and specify the threshold time, which is an allowable value of the recording time, and a radio button for specifying a desired setting item from these setting items are displayed. 97 and the setting end button 98 provided at the bottom are displayed.

A desired "threshold time" can be specified by the radio button 97 designated by the user, and the radio button 97 whose color has changed is designated. In this example, it is assumed that "2. Within 30 minutes (fixed) before and after" is set. The set value of this threshold time is stored in the storage device 67. The set value of the threshold time is read by the reservation control unit 59 and is a condition for generating the auxiliary recording reservation information.

For the setting items "1." to "3.", a threshold value within each M minutes (fixed) before and after can be set. The setting item "1." specifies within 10 minutes before and after as M minutes, the setting item "2." specifies within 30 minutes before and after as M minutes, and the setting item "3." specifies within 60 minutes before and after as M minutes. By specifying one of these setting items, recording of the corresponding channel (program) is executed retroactively within M minutes from the recording start time reserved for all recording recording. In addition, the recording of the corresponding channel (program) is executed by extending the recording end time to within M minutes.

For the setting items "4." to "6.", the threshold value of "within M minutes before and after" can be set, and the time that can be recorded retroactively from the recording start time and the recording end time can be extended. If the total time is within M minutes, recording is executed.
For the setting item "7.", the threshold value of "set by each program length" can be set, and the time to be recorded retroactively is determined according to the length of the program straddling the recording start time (for example, half the time of the program length). ). Similarly, the extended recording time is determined according to the length of the program that spans the recording end time.

For the setting item "8.", the threshold value of "set by recording time zone length" can be set. The recording time is determined in proportion to the length of the time zone set for recording (for example, 30 minutes for a 3-hour time zone and 50 minutes for a 5-hour time zone).

In the setting item "9.", the threshold value of "user setting" can be set, and the user can freely set the threshold time.

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

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

In this example, the radio button 97 is used for selection, but other methods such as a pull-down menu format and other selection methods may be used.

Hereinafter, the recording operation of the recording / playback device 1 will be described with reference to the flowchart of FIG.
In the case of the recording / reproducing device 1, the recording / reproducing processing unit 56 reads the recording reservation information of the complete recording reservation table 67a and the auxiliary reservation table 67b of the storage device 67 at the time of activation or at a predetermined time (for example, every 10 minutes) (FIG. FIG. Step S101 of 8).

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

The reservation control unit 59 extracts the broadcast information (program start time, end time) of the program from the acquired EPG information, and broadcasts it at the recording start time and / or the recording end time in the time zone of the read all-recording recording reservation information. It is confirmed whether or not there is a program that straddles (step S103).

As a result of this confirmation, if there is a program whose broadcast spans the recording start time and / or recording end time of the time zone, the start time and / or end time of the reserved recording is set to the broadcast start and / or end time of the program. The corrected auxiliary recording reservation information is generated (step S104) and stored in the auxiliary reservation table 67b.

Then, when the time reaches the recording start time of the recording reservation information such as the complete recording reservation table 67a and the auxiliary reservation table 67b, the recording / reproduction processing unit 56 records the program of the corresponding channel. That is, the recording / reproducing processing unit 56 performs recording based on the recording reservation information (step S105). At this time, the programs reserved in advance 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 is completed, the program determination unit 60 reads the attribute information of the program of the storage device 67 and the condition of the program failure from the storage device 67, collates it with the attribute information of the recorded program, and the recorded program is the program failure. It is determined whether or not the condition of is satisfied (step S106). It should be noted that this determination operation may be performed at all times during recording.

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

Further, as a result of the determination, when the condition that the program is not established is satisfied (Yes in step S106), the program determination unit 60 records the establishment flag of the program ID of the corresponding program in the recording information table 67c as “1” (step S108). ).

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

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

When the recording / playback device 1 receives an instruction from the remote control 71 (Yes in step S111), the program guide generation unit 58 refers to the recording information table 67c to select a screen for recording all recorded programs, that is, a time-shift machine past program. The table data is generated (step S112) and output to the display 26 through the OSD processing unit 24 and the display control unit 25 (step S113).

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

As shown in FIG. 9, the time-shift machine past program table 301 represents a program for playing a recorded program in a cell format on the vertical axis (channel) and the horizontal axis (time). It has the above program columns. That is, the time-shift machine past program table 301 displays the program column of the past recorded program in substantially the same form as the EPG 200 shown in FIG.

In the time-shift machine past program table 301, a recorded program can be played back and viewed by selecting a desired program column from a plurality of program columns by the remote controller 71.

Here, with reference to FIGS. 11 and 12, a method of clearly indicating when there is a program that is unsuccessful as content among the recorded programs will be described.
In the recording / playback device 1, when the program table generation unit 58 generates a program column of a reproducible recorded program, the recording information table 67c is referred to, and among the program columns, a establishment flag satisfying the condition of failure is set. The time shift machine past program guide data is generated in which the mark 303 (see FIG. 11) indicating that the program is unsuccessful as the content is added to the program column 302 of the program of "1".

In the time-shift machine past 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 the program satisfying the condition of failure, and the user can use the mark 303. If you look at it, you can see at a glance that the program is a program that is unsuccessful as content.

In this example, when a part of the program cannot be recorded, the triangular mark 303 is displayed in the corresponding program column 302, but in addition to this, for example, when the entire arbitrary program is interrupted due to an external factor. May display by adding a text message 305 such as "<(!) Time-shift machine recording was not possible.>" To the corresponding program column 304 as shown in FIG. As a result, in the time-shift machine past program table 301, the program column of the program that could not be recorded at all does not become blank (missing teeth), and the program that cannot be recorded at all can be identified from other unsuccessful programs, and the user can use it. The user can know that the recording could not be performed in the recording time zone specified by.

In the above embodiment, the operation when "10. No threshold value setting" is set on the threshold value setting menu screen 96 shown in FIG. 7 has been described, but in the following, it is shown in FIG. 7 with reference to FIGS. 13 to 16. The operation when each setting item is set on the threshold value setting menu screen 96 will be described.

First, referring to the flowchart of FIG. 13, the operation in the case of the setting item "2. Within 30 minutes before and after (fixed)" in which the radio button 97 is set to "●" on the threshold setting menu screen 96 of FIG. To explain. Since the operation in the case of the setting items "1." and "3." is different depending on whether the threshold time M is 10 minutes or 60 minutes, if the threshold time M is read from the explanation of the setting item "2." Often, the description of the setting items "1." and "3." is omitted.

In this recording / playback device 1, when the threshold value (allowable condition) of the setting item “2.” is set, the reservation control unit 59 sets the total recording time (recording) set in the total recording reservation table 67a of FIG. From the start time (start time, recording end time) and the broadcast information of the program extracted from the EPG information, it is determined whether or not there is a program to be broadcast over the entire recording time (step S211 in FIG. 13).

As a result of this determination, when there is a program to be broadcast over the entire recording time, the reservation control unit 59 reads out the preset threshold time M from the storage device 67 (step S212).

Subsequently, the reservation control unit 59 determines whether or not the time when the program is broadcast is before the recording start time (step S213).

When the time when the program is broadcast is before the recording start time (Yes in step S213), the reservation control unit 59 determines whether or not the time difference between the time when the program is broadcast and the recording start time is within the threshold time M. (Step S214).

As a result of this determination, when the time difference between the time when the program is broadcast and the recording start time is within the threshold time M (Yes in step S214), the reservation control unit 59 sets the recording start time of the program as the program. Auxiliary recording reservation information is generated so as to be the broadcast start time, and this is registered in the auxiliary reservation table 67b (step S215).

Further, as a result of the determination, when the time difference between the time when the program is broadcast and the recording start time exceeds the threshold time M (No in step S214), the reservation control unit 59 leaves the reserved recording information as it is. The recording information of the program is recorded in the recording information table 67c, and the flag "1" indicating that the program is not established is set in the establishment flag column (step S216).

On the other hand, as a result of the determination in step S213, when the time at which the broadcast of the program ends is after the recording end time (No in step S213, Yes in step S217), the reservation control unit 59 sets the time at which the broadcast of the program ends and the recording. It is determined whether or not the time difference from the end time is within the threshold time M (step S218).

As a result of this determination, when the time difference between the time when the program ends and the recording end time is within the threshold time M (Yes in step S218), the reservation control unit 59 broadcasts the recording end time of the program. Auxiliary recording reservation information is generated so as to be the end time, and this is registered in the auxiliary reservation table 67b (step S219).

When the above procedure is performed for the programs of all channels and 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. Within 20 minutes in total before and after” on the threshold value setting menu screen 96 of FIG. 7 is selected will be described. Since the operation in the case of the setting items "5." and "6." is different depending on whether the threshold time M is 30 minutes or 60 minutes, if the threshold time M is read from the explanation of the setting item "4." Often, the description of the setting items "5." and "6." is omitted.

In this recording / playback device 1, when the threshold value (allowable condition) of the setting item “4.” is set, the reservation control unit 59 sets the total recording time (recording) set in the total recording reservation table 67a of FIG. From the start time (start time, recording end time) and the broadcast information of the program extracted from the EPG information, it is determined whether or not there is a program to be broadcast over the entire recording time (step S230).

As a result of this determination, when there is a program to be broadcast over the entire recording time, the reservation control unit 59 reads a preset threshold time M from the storage device 67, and together with this, a counter set in a memory such as the RAM 54. The remaining time R of is reset, that is, set to "0" (step S231).

Subsequently, the reservation control unit 59 determines whether or not the broadcast of the program is started before the recording start time (step S232).

As a result of this determination, when the time when the broadcast of the program is started is not before the recording start time and the program is not started before the recording start time (No in step S232), the reservation control unit 59 has the remaining time R. The threshold time M is set to, that is, R = M (step S233).

Further, as a result of the determination in step S232, when the program is started before the recording start time (Yes in step S232), the reservation control unit 59 subsequently sets the time when the broadcast of the program is started and the recording start time. It is determined whether or not the time difference from the time is within the threshold time M. That is, it is determined whether or not the program starts within M minutes retroactively from the recording start time (step S234).

As a result of this determination, if the difference between the time when the program starts broadcasting and the recording start time is not within the threshold time M, that is, when the program does not start within M minutes (No in step S234), the reservation is made. The 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 failure as a program there (step S235).

Further, as a result of the determination in step S234, when the time difference between the time when the broadcast of the program is started 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 unit 59 generates auxiliary recording reservation information so that the recording start time of the program is set as the broadcast start time of the program, and registers this in the auxiliary reservation table 67b. Further, 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).

Then, the reservation control unit 59 confirms the remaining time R set in the counter (step S237). According to this confirmation, if the remaining time R is not "0" (No in step S237), that is, if the remaining time R remains, then the reservation control unit 59 ends the broadcasting of the program after the recording end time. Whether or not it is determined (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 has the remaining time of the difference between the time when the broadcast of the program ends and the recording end time. It is determined whether or not it is within the time R minutes. That is, it is determined whether or not the program ends within the remaining time R minutes later than the recording end time (step S239).

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

As a result of the determination in step S239, when the time difference between the time when the program broadcast ends and the recording end time is not within the remaining time R minutes, that is, when the program does not end within the remaining time R minutes (step S239). No), 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 failure as a program there (step S241).

When the above procedure is performed for the programs of all channels and all channels are checked (Yes in step S242), the process ends.

With reference to the flowchart of FIG. 15, the operation in the case of the setting item “7. Setting by each program length” on the threshold value setting menu screen 96 of FIG. 7 will be described.

In this recording / playback device 1, when the setting item "7." is set, the reservation control unit 59 uses the total recording time (recording start time, recording end time) set in the total recording reservation table 67a of FIG. ) And the broadcast information of the program extracted from the EPG information, it is determined whether or not there is a program to be broadcast over the entire recording time (step S250).

As a result of this determination, when there is a program to be broadcast over the entire recording time (Yes in step S250), the reservation control unit 59 subtracts the broadcast start time from the broadcast end time of the program included in the broadcast information of the program. It is possible to calculate the length L (broadcast time, unit is hours or minutes) of the program, and start recording half the time (L / 2) of the calculated length L of the program retroactively from the recording start time. Let it be a possible allowable time, that is, a threshold time M that can be traced back to the program broadcast start time (step S251).
Subsequently, the reservation control unit 59 sets the program to be broadcast over the recording start time from the recording start time from the total recording time (recording start time, recording end time) and the broadcast information of the program extracted from the EPG information. Also, it is determined whether or not the broadcast is started before (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 the difference between the time when the program broadcast starts and the recording start time. It is determined whether or not the time is within the threshold time M. That is, it is determined whether or not the program starts within the threshold time M which is 1/2 of the length L of the program retroactively from the recording start time (step S253).

As a result of the determination, when the time difference between the time when the program starts broadcasting and the recording start time exceeds the threshold time M, that is, when the program does not start within the threshold time M minutes (No in step S253), the reservation is reserved. The control unit 59 records the recording information of the program in the recording information table 67c while leaving the reserved recording information as it is (without generating the auxiliary recording reservation information), and the establishment flag column indicates that the program is not established. The flag “1” indicating the above is set (step S254). Recording the recorded information of the program means generating a new record of the program ID in the recording information table 67c of the program and setting a flag "1" indicating failure as a program there.

Further, as a result of the determination in step S253, when the time difference between the time when the broadcast of the program is started and the recording start time is within the threshold time M, that is, when the program starts within the threshold time M minutes (step S253). Yes), 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 this in the auxiliary reservation table 67b (step S255).

On the other hand, as a result of the determination in the determination step S252, when the broadcasting of the program straddling the recording time does not start before the recording start time (No in step S252), the reservation control unit 59 then determines the program straddling the recording time. However, it is confirmed whether or not the recording ends after the recording end time (step S256).

As a result of this confirmation, when the broadcast of the program ends after the recording end time (Yes in step S256), the reservation control unit 59 determines that the time difference between the time when the program broadcast ends and the recording end time is L / It is determined whether or not it is within the threshold time M minutes of 2 (step S257).

As a result of this determination, when the time difference between the time when the broadcast of the program ends and the recording end time is within the threshold time M (Yes in step S257), the reservation control unit 59 sets the recording end time of the program as the program. Auxiliary recording reservation information is generated so as to be the broadcast end time of, and this is registered in the auxiliary reservation table 67b (step S258).

As a result of the determination in step S257, when the time difference between the time when the program broadcast ends and the recording end time exceeds the threshold time M minutes, that is, when the program broadcast does not end within the threshold time M ( No) in step S257, the reservation control unit 59 sets the flag in step S254 without generating auxiliary recording reservation information.

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

Here, a specific example of retroactive recording or extended recording will be described.
If the program is, for example, a 2-hour program (L = 120 minutes), the threshold time M = 120 (L) × (1/2) = 60 minutes is the target of retroactive recording or extended recording. If the threshold time M is exceeded, recording is performed as before, and the recording time does not follow.

In this case, in the EPG 200 of FIG. 3, the start time of the program 221 of "Variety A" is 6:50 PM, the length L of the program is 70 minutes, and M = 70 × (1/2) = 35 minutes. Since it is within the range of the "threshold", the recording / reproducing device 1 of the present embodiment can prevent the head from being cut off.

Further, in the EPG 200 of FIG. 3, the end time of the program 222 of "Movie B" is 10:30 PM, the length L of the program is 150 minutes, and M = 150 × (1/2) = 75 minutes. Therefore, since it is within the range of the "threshold", the recording / playback device 1 of the present embodiment can prevent the end of the tail from being cut off.

Similarly, in the EPG 200 of FIG. 3, the broadcast start time of the program 223 of "special number C" is PM 6:30 start, the broadcast end time is PM 11:00 end, and the program length L is 270 minutes, M =. Since it is up to 270 × (1/2) = 135 minutes and is within the range of the threshold time M, the recording / playback device 1 of the present embodiment can prevent head cutting and tail cutting.

Next, the operation when the setting item "8. Setting by recording time zone length" on the threshold value setting menu screen 96 of FIG. 7 is selected with reference to the flowchart of FIG. 16 will be described.

In this recording / playback device 1, when the setting item "8." is set, the reservation control unit 59 uses the total recording time (recording start time, recording end time) set in the total recording reservation table 67a of FIG. ) And the broadcast information of the program extracted from the EPG information, it is determined whether or not there is a program to be broadcast over the entire recording time (step S260).

As a result of this determination, if there is a program that is broadcast over the entire recording time, the reservation control unit 59 subtracts the recording start time from the recording end time in order to set the recording time zone length, and sets the value to 1. Multiply by 6 to calculate the threshold time M. 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, in the case of recording start time 19:00 and recording end time 10:00, the value obtained by subtracting the recording start time from the recording end time is 3 hours, and when this is multiplied by 1/6, 1/2 hour. That is, it becomes 30 minutes, and this is set as the threshold time M.

Subsequently, the reservation control unit 59 determines whether or not the broadcast of the program is started before the recording start time (step S262).

As a result of this determination, when the broadcast of the program is not started before the recording start time (No in step S262), the reservation control unit 59 sets the threshold time M in the remaining time R, that is, sets R = M (step). S263).

Further, as a result of the determination in step S262, when the broadcast of the program is started before the recording start time (Yes in step S262), the reservation control unit 59 subsequently sets the time when the broadcast of the program is started. It is determined whether or not the time difference from the recording start time is within the threshold time M minutes. That is, it is determined whether or not the program starts within M minutes retroactively from the recording start time (step S264).

As a result of this determination, when the time difference between the time when the program starts broadcasting and the recording start time is not within the threshold time M, that is, when the program does not start within M minutes retroactively from the recording start time (step). No) of S264, 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 unsuccessful there (step S265).

Further, as a result of the determination in step S264, when the time difference between the time when the program starts broadcasting and the recording start time is within the threshold time M, that is, the program starts within M minutes retroactively from the recording start time. In the case (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 registers this in the auxiliary reservation table 67b. Further, 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). According to this confirmation, if the remaining time R is not "0" (No in step S267), that is, if the remaining time R remains, then the reservation control unit 59 ends the broadcast of the program after the recording end time. Determine whether or not to do so. That is, it is determined whether or not the program ends after the recording end time (step S268).

As a result of this determination, when the broadcast of the program ends after the recording end time (Yes in step S268), the reservation control unit 59 has the remaining time of the difference between the time when the broadcast of the program ends and the recording end time. It is determined whether or not it is within the time R. That is, it is determined whether or not the program ends within the remaining time R minutes later than the recording end time (step S269).

As a result of the determination, when the time difference 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, when the program ends within the remaining time R (Yes in step S269), the reservation control Unit 59 generates auxiliary recording reservation information so that the recording end time of the program is set to the broadcast end time of the program, and registers this in the auxiliary reservation table 67b (step S270).

Further, as a result of the determination in step S269, the time difference between the time when the program broadcast ends and the recording end time is not within the remaining time R minutes, but the time from the recording end time to the program broadcast end time is the remaining time R. (No in step S269), the reservation control unit 59 generates a new record of the program ID in the recording information table 67c of the program without generating the auxiliary recording reservation information, and indicates that the program is not established there. The flag "1" is set (step S271).

When the above procedure is performed for the programs of all channels and all channels are checked (Yes in step S272), the process ends.

As described above, according to this recording / playback device 1, recording is started retroactively from the program start time based on the broadcast information of the program that starts before the recording start time specified in advance for all recording, and all in advance. Based on the broadcast information of the program that ends after the recording end time specified in the recording, the recording is extended to the program end time, so it is possible to prevent the program from being cut off and the end of the program, and the user's dissatisfaction is reduced. You can expect the effect of making it.

Further, according to the present embodiment, the preset retroactive time and / or the extended time is set as the "threshold time M", and the recording start time set in advance by the target program can be retroactively recorded and / or set in advance. Since it is determined whether recording is possible by extending the recording end time and recording is performed, the capacity of the recording medium such as HDD is not recorded at a time significantly deviating from the time zone set by the user. There will be no inconvenience such as squeezing.

Further, according to the present embodiment, the threshold time M is obtained by using the program length L and the recording time zone length of the target program as calculation reference values, and the program within M minutes is followed and recorded, which is useless for the user. It is possible to retroactively record or extend the program that is slightly out of the time zone recording without any hassle. As a result, the recording start time set by the user is recorded retroactively or extendedly by setting the allowable time (threshold time M) for the program that straddles the recording start time and the recording end time set by the user with the full recording function. In addition, it is possible to eliminate programs that deviate significantly from the recording end time, and to relieve programs with minor head cuts or tail cuts.

In addition, by setting the threshold time M, programs that exceed the threshold time M are not retroactively recorded or extended recording, so that programs that are not established as content may be recorded. When a program that is not established as content is recorded along with a program that was not recorded or a program that was inadvertently operated during recording, if there is an instruction operation to play the recorded program, the program guide generation unit In 58, the program is not established in the program column 302 of the program (program that is not established as content) that satisfies the condition among the program columns of the recorded program based on the attribute information of the program and the establishment flag of the recording information table 67c. Time shift machine with a mark 303 to indicate that the past program table 301 is generated and displayed, so that the beginning or end of the program is missing, the program is missing due to a signal defect, or part or all of the program can be recorded. The user can grasp a program that does not exist (a program that is not established as content) by simply looking at the program column 302 of the time shift machine past program table 301 without viewing the program.

In the above embodiment, an example in which a triangular mark 303 is added to the lower right corner of the program column 302 is shown, but in addition to this, for example, depending on the cause (user operation or recording setting) that the program is not established as content. The display form of the mark 303 may be changed (the position of the mark 303 may be changed, characters such as a program name or program information may be grayed out, or the color of the mark 303 may be changed).

For example, if the cause of the program failure is a time mismatch in the recording settings, or if the recording end time is a mismatch and the program is cut off, a mark 303 is added to the right corner of the program column 302, and the recording start time does not match and the head is cut off. In the case of the program of, the mark 303 may be added to the left corner of the program column 302. Further, the mark 303 may be added to the positions of both the left and right corners of the program column 302 of the program determined to be unsuccessful due to either the head cut or the tail cut.
