Description

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

Conventionally, the recording function of a recording device such as a BD recorder has the following functions.
For example, there is a program guide selection recording function for recording a program by selecting a program from an electronic program guide (EPG) displayed on a television screen or making a recording reservation by designating a date and time. There is also a manual recording function that records the program being watched by pressing the "record button".

Furthermore, by specifying the channel to record and the time zone to record in advance, the function to automatically record the program in the time zone, so-called "round recording function" or "all recording function" (for example, "time shift machine") There is a function called "function"). With the time-shift machine function, recorded programs can be displayed as if they were an electronic program guide (EPG) (this is called a past program guide), and can be played back by selecting and operating a desired program from the past program guide. ..

By the way, among the programs recorded by these recording functions, there are differences between the recording start (end) time and the broadcast start (end) time of the program, the function limitation of the recording device, careless user operation, and other matters. Depending on external factors (changes in the radio reception environment, etc.), the beginning or end of the program may be missing, part of the program content may be missing due to a signal failure during recording, or part or all of the program may not be recorded. It may be in a state.

Conventionally, there is a technique of displaying an execution history list on the display unit, which can confirm whether or not the reserved item recorded by reservation is actually executed. With this technology, the user confirms the display of the corresponding item in the execution history list to see if scheduled recording was executed normally, and if there is a problem during scheduled recording, head chipping or back chipping, etc. You can check detailed information such as the recording execution status of the video recording and the cause of the recording failure.

Japanese Unexamined Patent Publication No. 2005-117448

However, with the conventional technology, the only way to confirm whether the scheduled recording was performed correctly is to display a confirmation-only screen such as the execution history list to confirm, and after confirmation, return to the original screen and use it for program playback. It cannot be said that the operability is good because the procedure of displaying the list (past program guide) of the program, playing it back, and watching it is taken. For this reason, in reality, the failure of scheduled recording of a program can be found only after the corresponding program is selected from the past program table at the time of program playback and the playback operation is performed to play the program.

That is, when a program that is incomplete (unsuccessful) as content is played back without being understood by the user, the program is played back halfway, so that there is a possibility of unnecessary viewing.

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.

The problem to be solved by the present invention is to provide an electronic device and a program list generation method that can intuitively determine the recording status of a recorded program only by a user looking at a list for playing a recorded program. There is something in it.

The electronic device of the embodiment includes a recording unit, a program information storage unit, a program determination unit, and a program guide generation unit. The recording unit records a program designated for recording in advance in a time zone. The attribute information for each recorded program is stored in the program information storage unit.

For example, the storage device 6 connected to the USB interface 65 has a time-shift machine function (a time-shift machine function) that records all programs of a specific channel (broadcaster or distributor) designated by the user and a program in a predetermined time zone for a certain period of time. All program recording function: Recording by "all recording function" or "loop recording function") is possible.

Further, the storage device 7 connected to the USB interface 66 can schedule or manually record a program individually designated by the user from the electronic program guide (EPG). In this example, an example in which two external storage devices are connected has been described, but a combination of a built-in storage device and an external storage device may be used, and three or more external storage devices are connected. You may.

The HDMI interface 68 enables wired communication between devices using the HDMI (High-definition Digital Media Interface (registered trademark)) standard or the MHL (Mobile High-definition Link) standard.

The HDMI interface 68 is connected to a recorder that records programs independently of the recording / playback device 1, or another recorder or television device that connects to the home server in a home network that uses the home server.

As a result, the program (video data including audio) received by the recording / playback device 1 and recorded in the storage devices 6 and 7 can be viewed on another television device connected to the home server. Further, the recording / playback device 1 can reproduce a program recorded by the recorder or another recorder connected to the home server.

The storage device 67 contains recording reservation information for scheduled recording in which the user specifies a channel (or program name) and a date and time to record in program units, and recording of a program actually recorded in the storage devices 6 and 7. Attribute information related to the content is retained (stored). 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.

These information are information 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).

The storage device 67 stores a condition that the program is unsuccessful (incomplete) as content. As an example of the condition, for example, the actual time zone (recording start time, recording end time) when the program was actually recorded and the program time zone (recording start time, recording end time) on the electronic program table for which the program was reserved for recording. When the time does not match (when there is a time lag between the recording start time and the recording end time).

Other conditions include, for example, a case where a part of the recorded program includes an unrecorded part, a case where there is a user operation that affects the recording during the recording of the program, and the like. 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.

Specifically, this device is provided with a card slot in which a storage medium for viewing such as terrestrial digital broadcasting such as a B-CAS card and pay broadcasting is installed, and the storage medium is installed in the card slot. It will be available for viewing. The attachment / detachment of the storage medium is detected by the main control block 51.

Further, the storage device 67 stores the condition that the program is not established as the content. That is, the storage device 67 functions as a condition storage unit in which the condition that the program is not satisfied as the content is stored.

Here, the conditions under which the program is not established as content are, for example, the time zone (recording start time, recording end time) in which the program is set to be recorded and recorded, and the time zone of the program on the electronic program guide (EPG) (of the program). This is the case when the broadcast start time and the broadcast end time of the program do not match.

In addition, there is a user operation that affects the recording during the recording of the program when the condition using the default detection function of the recording / playback device 1, for example, when a part of the recorded program includes an unrecorded part. It may be the case. The user operation that affects the recording is, for example, when the user operates the remote controller 71 in the middle of the program to switch between <use> and <not use> in the time shift machine recording setting, or during recording. When the recording mode (recording operation mode) is changed to, either of them may be used.

The program may be unsuccessful as content due to hardware function restrictions or inadequate reception contracts, such as B-CAS card not inserted, antenna not connected, reception failure, recording prohibited program. If a part of the uncontracted program of pay broadcasting was recorded in a state where it can be played, one of them corresponds to.

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) has a 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 acquisition 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 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 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 desired video signals, audio signals, etc. 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 renders the video decoder 22 and the audio decoder. Output to 32.

The recording / playback processing unit 56 starts recording in one 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 / reproduction processing unit 56 stores attribute information (recording management information of the recorded program) related to the target program in the storage device 67. That is, the recording / reproduction processing unit 56 functions as a recording unit for recording the programs designated for recording in advance in the time zone and / or the programs set to be recorded by the time shift machine function in the storage devices 6 and 7 and the storage device 67. Further, the storage device 67 functions as a program information storage unit in which 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 management table 67a (see FIG. 4) for each program ID. The contents of the recording management table 67a 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 program guide data (EPG data) is converted into a program guide display signal by the OSD processing unit 24 and output to 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 management table 67a 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 information in the above, 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 status is "1" in the recording management table 67a, which satisfies the condition among the program columns included in the data. A mark indicating that the content is unsuccessful is given.

It is a table that stores the end time) and the establishment status in association with each other.

In the establishment status column, "1" or "0" is set as the determination result of failure / establishment of the program by the program determination unit 60. If the program is unsuccessful (incomplete), "1" is set, and if the program is established as content (complete), "0" is set.

Hereinafter, the operation of the recording / playback device 1 will be described with reference to FIGS. 5 to 7.
In the case of the recording / playback device 1, the recording / playback processing unit 56 reads the recording reservation information of the storage device 67 (step S101 in FIG. 5), and when the time reaches the recording start time (Yes in step S102), recording is performed. When it starts (step S103) and the recording end time comes (Yes in step S104), the recording ends (step S105). At this time, the program reserved for recording in advance is recorded in the storage devices 6 and 7 by the recording / playback processing unit 56, and the attribute information of each program is stored in 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, and determines whether or not the recorded program satisfies the condition of the program failure. (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 status of the program ID of the corresponding program in the recording management table 67a as “0” (step S107).

If, as a result of the determination, the condition that the program is not established is satisfied (Yes in step S106), the program determination unit 60 records the establishment status of the program ID of the corresponding program in the recording management table 67a as "1" (step S108). ).

Then, 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 of FIG. 3 (step S110 of FIG. 6).

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 management table 67a when generating a program column of a reproducible recorded program. , A time shift machine past program guide data is generated in which a mark 303 indicating that the program is unsuccessful as content is added to the program column 302 of the program whose establishment status is "1" that satisfies the condition of unsuccessfulness in the program column. (Step S112), and output to the display 26 through the OSD processing unit 24 and the display control unit 25 (step S113).

In the time-shift machine past program table 301 (see FIG. 3) displayed on the screen of the display 26, as shown in FIG. 7, the mark 303 is displayed in the program column 302 of the program satisfying the condition of failure. When the user sees the mark 303, it can be seen at a glance that the program is a program that is not established as content.

As described above, according to the recording / playback device 1, when the condition that the program is not established as the content is stored in advance and there is an instruction operation to play the recorded program, the program guide generation unit 58 will perform the program guide generation unit 58. Based on the program attribute information and the establishment status of the recording management table 67a, it is shown that the program is not established in the program column 302 of the program satisfying the condition (the program that is not established as the content) among the program columns of the recorded program. Since the time shift machine past program table 301 with the mark 303 is generated and displayed, the beginning or end of the program is missing, the program is missing due to a signal defect, or a part or all of the program cannot be recorded ( The user can grasp the program (a program that is not established as content) simply by looking at the program column 302 of the time shift machine past program table 301 without viewing the program.

That is, the user can intuitively determine the recording status of the recorded program just by looking at the time-shift machine past program table 301 of the recorded program, and avoid causing the user to uselessly watch the program. be able to.

In the above embodiment, the triangular mark 303 is displayed in the corresponding program column 302 when a part of the program cannot be recorded, but in addition to this, for example, when the entire arbitrary program is interrupted due to an external factor. , As shown in FIG. 8, a text message 305 such as "<(!) Time-shift machine could not record.>" May be added to the corresponding program column 304 and displayed. 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, 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.
