Description

Schedule recording method of broadcast program, and system {Method and Apparatus for reservation recoding of broadcasting program}

The present invention relates to a digital broadcasting system. More specifically, when a user requests reservation recording information, the user can identify a broadcast program that cannot be reserved or a broadcast program that can be reserved, and reserves the broadcast program that cannot be reserved. The present invention relates to a scheduled recording method and a system capable of providing a solution for recording.

Digital broadcasting (DB) is a system that compresses and transmits broadcast signals such as video and audio information in the form of digital signals at broadcasting stations.

Conventional analog broadcasts carry only one image on one radio wave and transmit it in the form of an analog signal, and the analog signal is gradually separated from the transmitter (for example, a broadcasting station) and a receiver or is sensitive to the influence of external noise. There was a lot of information loss. However, in digital broadcasting, there is almost no information loss by compressing a plurality of video, audio, and broadcasting information in one radio wave and transmitting it as a digital signal. Accordingly, the digital broadcast is excellent in resilience of the broadcast signal and can transmit a lot of information at once, thereby enabling high quality, multi-channel, and various additional data services.

The digital broadcasting system is a system that receives a broadcast signal using the digital broadcast receiver (eg, a set-top box), restores the broadcast signal to a video and audio signal, and reproduces the broadcast signal on a display device.

The set-top box is a control device capable of receiving a broadcast and implementing various additional functions, and is a terminal required for using next-generation bidirectional multimedia communication. The set-top box receives a broadcast signal (digital video signal, or analog signal) transmitted from a broadcasting station through a transmission medium such as over-the-air (terrestrial wave), cable, satellite, or high speed network, and decodes the broadcast signal to display the display device ( For example, a TV or monitor) converts the signal into a signal that can be recognized.

In the conventional set-top box, the main function was to receive a broadcast signal transmitted from a specific broadcaster. However, as digitalization of broadcasts has recently accelerated, various additional functions such as interactive data communication and PVR functions have been added.

On the other hand, PVR (Personal Video Recorder) is a next-generation recording device capable of receiving a broadcast signal (eg, digital video signal, analog signal) in real time and storing (recording) in a storage device (eg, hard disk). to be.

The PVR is broadcast information transmitted by a user in real time with a broadcast program, that is, reservation recording information (eg, broadcast time, broadcast program title, etc.) of any one of a plurality of broadcast programs based on the latest broadcast schedule list. ), The broadcast signal of the broadcast program received for a predetermined time may be converted into a digital signal and recorded (stored) in a storage device (for example, a hard disk).

As the number of broadcast channels and broadcast programs increases, there is a growing interest in a reservation recording system that allows a user to watch a specific broadcast program at a desired time according to individual selection and taste, that is, to provide a personalized broadcast service. .

In the existing reservation recording system, when a user requests a reservation recording, the user is provided with information on a program or time for which reservation recording has already been registered (set). The registration (setting) of the reservation recording in the existing reservation recording system is performed by the user directly inputting the set-top box through an input device (for example, a remote controller) or by using a data processing device such as a PC to reserve recording information. It may be performed by setting (or uploading), the web server to set the reservation recording information to the set-top box.

However, according to the existing reservation recording registration method, when a user wants to set up a new reservation recording, the user is provided with information about a program that is already registered in the reservation recording. It is inconvenient to analyze directly whether the program is capable of pre-recording. In other words, the user has a request for whether the program that he / she wants to reserve is available for recording, and how the reserved recording can be made by changing the reserved recording setting. Will not be big. Such a demand may be increased when the number of broadcast reception tuners included in the digital broadcasting receiver (eg, set-top box) is large and the number of broadcast programs capable of recording in the same time period is large.

Therefore, there is a need for a reservation recording method and a system capable of easily checking a program for which a reservation recording setting is not possible or providing a method for easily adding a reservation recording item.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a reservation recording method and a system for easily checking a program that cannot be scheduled recording and / or a program capable of setting reservation recording, and easily adding a reservation recording item.

According to an exemplary embodiment of the present invention, there is provided a reservation recording method comprising: receiving, by a recording setting apparatus, at least one reserved recording information for recording any one of a plurality of broadcast programs; Receiving a reservation recording confirmation request signal output from an input device; And in response to the reserved recording confirmation request signal, the recording setting apparatus, based on the at least one reserved recording information, a broadcast program that is not available for scheduled recording, a time when scheduled recording is impossible, and a scheduled recording available among the plurality of broadcast programs. And displaying recording confirmation information including at least one of a program or information on a time when reservation recording is possible.

When the scheduled recording of any one broadcast program is impossible, the reserved recording method may display change information for deleting or changing the existing reserved recording information so as to perform scheduled recording of the broadcast program.

The reserved recording method displays re-broadcast information of at least one broadcast program in which reservation recording is set based on EPG information received from a broadcasting station so that reservation recording of any one broadcast program is impossible. can do.

The recording confirmation information may be displayed in a different form by comparing the broadcast program that cannot be scheduled recording or the broadcast program that can be reserved recording with broadcast information of the remaining broadcast programs.

The recording setting device may be included in at least one of a set top box or a server connected to the set top box through a wired or wireless network.

A reservation recording system according to an embodiment of the present invention includes a first input device for inputting reservation recording information for recording any one of a plurality of broadcast programs; And a recording setting device that receives a corresponding broadcast signal based on the reserved recording information.

The recording setting device receives at least one reserved recording information for recording any one of a plurality of broadcast programs, receives a reserved recording confirmation request signal output from a second input device, and confirms the reserved recording. In response to the request signal, the recording setting apparatus determines whether the scheduled recording is not possible from among a plurality of broadcast programs based on the at least one reserved recording information, a broadcast program that cannot be scheduled recording, a broadcast program that can be scheduled recording, or a scheduled recording. The recording confirmation information including at least one of the information on the available time may be displayed.

When the scheduled recording of any one broadcast program is impossible, the reserved recording system may display change information for deleting or changing the existing reserved recording information so as to perform scheduled recording of the broadcast program.

The reservation recording system displays rebroadcast information of at least one broadcast program in which reservation recording is set based on EPG information received from a broadcasting station so that reservation recording of any one broadcast program is impossible. can do.

In the reservation recording system according to the present invention, before registering the reservation recording information of any one broadcast program, information about broadcast programs and broadcast time that cannot be reserved by the previously registered reservation recording information and / or reservation recording By displaying information on broadcast programs and broadcast time, which is possible, the user can simply set reserved recording information without comparing broadcast information of a plurality of broadcast programs.

In addition, the reservation recording system according to the present invention displays the change information for changing the reserved recording information registered in order to register the reservation recording information of the broadcast program when the user-selected broadcast program can not be scheduled recording You can easily change the scheduled recording information.

In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

1 is a block diagram showing a schematic configuration of a digital broadcasting system according to an embodiment of the present invention. 2 is a schematic functional block diagram of a reserved recording system according to an embodiment of the present invention.

1 and 2, the digital broadcasting system may include an input device 17, a set top box 13, a broadcasting station 15, and a display device 11 such as a digital TV.

The input device 17 may transmit reserved recording information of a broadcast program selected by a user to at least one set-top box (hereinafter referred to as 'STB', 13). The reserved recording information may include at least one of information on a broadcast channel, a broadcast program title, or a broadcast time.

The apparatus for setting recording according to an embodiment of the present invention may be implemented by being included in at least one of the STB 13 or the server 14 connected to the STB 13 through a wired or wireless network.

For example, the recording setting device may be implemented by a combination of a processor such as a CPU included in the set-top box and a predetermined firmware for driving the processor. When the recording setting device is included in the STB 13, The STB 13 stores reservation recording information input from the input device (eg, a remote controller or a mobile terminal 17 that can interface with the STB 13, a computer, etc.) and stores the reservation recording information in the reservation recording information. Record the corresponding broadcast program.

The user outputs a user request signal (eg, a signal corresponding to reproduction, stop, repetition, and reservation recording information input, etc.) to the STB 13 through the input device 17 to perform functions of the STB 13. Can be controlled. When the input device 17 is implemented outside of the STB 13, the input device 17 is a mobile controller such as a remote controller, a PDA, a PC, and a mobile phone that can communicate with the STB 13 remotely. It may be a terminal.

In addition, when the recording setting device is included in the server 14 connectable to the STB 13 via a network (for example, the Internet), the recording setting device includes predetermined hardware and bones included in the server 14. It may be implemented by a combination of predetermined software for carrying out the technical idea of the invention. In this case, the input device 17 may be various data processing devices capable of interfacing with the server 14 such as a computer. For example, a user may connect their computer to the server 14 providing a digital broadcasting related service and register reservation recording information with the server 14 using a computer instead of an uncomfortable input interface such as a remote controller. . Then, the server 14 may transmit the reservation recording information registered by the user to the STB 13 through communication with the STB 13. As such, when the recording setting device is implemented in the server 14, the reserved recording information stored in the STB 13 and the server 14 may be synchronized or may be synchronized at regular time intervals. Then, the user can check the information on the program that can make a reservation recording and / or the program that can not directly in the server (14). In this case, only information on a program that can be reserved can be transmitted to the STB 13, thereby reducing the data processing load on the STB 13.

Meanwhile, an input device for inputting reservation recording information and an input device for requesting reservation recording confirmation may be different from each other. For example, the user can input reservation recording information into the STB 13 by registering reservation recording information with the server 14, and a reservation recording confirmation request can be made through a remote controller or his computer. Of course, the input device for inputting the reservation recording information and the input device for requesting the reservation recording confirmation may be the same.

In addition, the reserved recording information may be input by a plurality of users using each of the different input devices 17. For example, one user inputs the first reserved recording information to the STB 13 through the first input device, and the other user confirms the recording confirmation information previously set in the STB 13 through the second input device. 2 You can enter reservation recording information. In this case, it can be easily inferred by an average expert in the art that the method of processing duplicate reservation recording requests may vary according to implementation.

The display device 11 may be a digital TV, a monitor, a display device of a user computer, or the like. In addition, the display device 11 may be included in the input device 17. For example, when the input device 17 is a user's mobile terminal, the display device 11 may be a display device provided in the mobile terminal.

The broadcasting station 15 generates one broadcast signal (or digital video signal) by compressing video and audio information and EPG information of a broadcast program, and converts the broadcast signal into an air wave (terrestrial wave), a cable, a satellite, or a high speed network. It is sent through the transmission medium of. Therefore, the broadcasting station in the present specification should be interpreted to include all media that transmit a broadcast program.

Referring to FIG. 2, the STB 13 may include a CPU 21, a ROM 23, a RAM 25, a signal processor 35, a storage medium (eg, a hard disk 37), and a first tuner unit 31. ), And a second tuner unit 33. In the present specification, for convenience of description, a system having two tuner units will be described as an example, but is not limited thereto.

The CPU 21 is a device for controlling the entire system, and controls and adjusts each of a series of processes according to the input / output signals of the STB 13. The ROM 23 stores a driving program (for example, firmware for performing the technical idea of the present invention) for performing an operation such as recording / playback, and the RAM 25 is received from the input device 17. User request signals such as reserved recording information, reproduction signals, and stop signals, and data temporarily generated during program execution.

Each of the first and second tuner units 31 and 33 receives a corresponding one of a plurality of digital image signals, respectively.

 The STB 13 may simultaneously receive broadcast signals of two different broadcast programs having overlapping broadcast times, through the first and second tuner units 31 and 33. The number of broadcast signals that the STB 13 can simultaneously receive may be equal to the number of tuners.

The signal processor 35 restores the broadcast signals transmitted from the first and second tuner units 31 and 33 into digital signals and outputs them to the display device 11 or to a storage medium (for example, a hard disk 37). Can be stored.

In addition, when the signal processor 35 intends to reproduce the information stored in the storage medium (eg, the hard disk) 37, the signal processor 35 outputs a digital signal of a corresponding broadcast program in response to the playback signal. 37, and the read digital signal may be output to the display device 11.

On the other hand, EPG (Electronic Program Guide) information is separated from the video and audio data by the signal processing unit 35 and the CPU 21, and when the user request, for example, in response to a broadcast schedule confirmation request, the display device 11 The menu providing screen may be displayed on any one of the input devices 17. The set top box 13 may collect the EPG information not only in the data stream received from the broadcasting station but also through the internet network. The EPG information may be provided to the user along with a predetermined interface when the user wants to make a reservation recording.

Meanwhile, as described above, when the recording setting device is included in the server 14 and implemented, the reservation recording information may be received by the STB 13 through the server 14. In this case, the reserved recording information input by the user through the input device 17 is registered in the server 14. The STB 13 may update the reserved recording information set in the set-top box 13 with the reserved recording information registered in the server 17 by communicating with the server 14 in real time. Therefore, the reservation recording information stored in the server 14 may be synchronized with the reservation recording information stored in the STB 13 in real time.

For example, the user may register reserved recording information of the first broadcast program through an input device (eg, PC) 17. Then, the server 14 determines whether the first broadcast program can be reserved based on the reserved recording information synchronized with the reserved recording information stored in the STB 13, and if the reserved recording is possible, The reserved recording information of one broadcast program can be transmitted to the STB 13 to be set. If reservation recording is not possible, recommendation information may be provided to the user according to the technical spirit of the present invention described later. That is, when the recording setting device is included in the server 14, before the scheduled recording information is actually transmitted to the STB 13, whether or not the reservation is possible on the server 14 side and the recommendation information are directly fed back ( feedback). It works. Therefore, since the STB 13 does not proceed with the reservation recording process at all, there is an effect of reducing the load of the STB 13 itself. Even if the STB 13 is powered off, the server 14 reserves the recording. There is an effect that you can immediately check whether it is possible.

Meanwhile, when the recording setting device is included in the STB 13, the reserved recording information may be received through the server 14 or directly through the input device 17. Then, the recording setting device may provide the user with information on whether or not a reservation recording is possible according to the technical idea of the present invention, and may provide recommendation information when it is impossible.

Hereinafter, the case where the recording setting device is included in the STB 13 will be described as an example. However, the scope of the present invention is not limited thereto.

3 is a flowchart illustrating a reservation recording method according to an exemplary embodiment of the present invention.

The STB 13 may display the recording confirmation information on the display apparatus 11 in response to the reserved recording confirmation request signal (S1).

The reserved recording confirmation request signal may be a display request signal of a reserved recording enable / disable program requested from an input device in a recording setting mode provided by the STB 13. In addition, the reserved recording confirmation request signal may be simply an EPG information request signal input from a user while watching a broadcast. That is, the case of displaying the recording confirmation information according to the embodiment of the present invention may vary according to the embodiment. For example, even when the user outputs the EPG request signal to the STB 13f to check the EPG information regardless of the reservation recording setting, the STB 13 displays the recording confirmation information according to the embodiment of the present invention. can do. As a result, the reserved recording confirmation request signal may be interpreted to include all signals that cause the STB 13 to display the recording confirmation information.

The recording confirmation information may be used as a meaning including all information that can display a reserved recording and / or disabled programs according to an embodiment of the present invention. The recording confirmation information is generated based on previously registered reservation recording information, and is for broadcast programs that cannot be scheduled broadcast recording or for a time when reservation recording is impossible, for broadcast programs that can be reserved recording, or for a time when reservation recording is possible. It includes at least one of the information. The recording confirmation information may include at least one of a color, an image, or text. In the scheduled recording method according to an exemplary embodiment of the present invention, recording confirmation information of a program that cannot be scheduled recording or recording confirmation information of a program capable of scheduled recording May be displayed so that the broadcast information of the remaining broadcast programs and at least one of the color, the image, or the text are displayed in different forms so that the user can easily distinguish them. The display method of the recording confirmation information can be described with reference to FIGS. 4A and 4B.

4A illustrates an example of an EPG screen for describing a reservation recording method according to an embodiment of the present invention, and FIG. 4B illustrates another example of an EPG screen for describing a reservation recording method according to another embodiment of the present invention. .

Referring to the reservation recording method according to an embodiment of the present invention with reference to Figures 4a and 4b, when the user makes a reservation recording confirmation request through the input device, the set-top box 13 is shown in Figures 4a and 4b The screen as shown can be displayed. 4A illustrates an example of displaying a program that cannot be reserved, and FIG. 4B illustrates displaying a program that may be reserved. Displayed herein may be used as a meaning including transmitting an information to be displayed to a display device and performing an operation of controlling the display device to be displayed on the display device.

In FIG. 4A, since the news program 1 is a program for which reservation recording has already been established, the news program 1 may have a predetermined display (eg, ®). The movie program 2 may be a program capable of scheduled recording. In addition, if the baseball program 3 is a program that cannot be scheduled recording, the baseball program 3 may be displayed in a different form from a program that can be reserved recording or a program that has already been scheduled recording. For example, an OSD (On Screen Display) interface representing each program may have a different color.

For example, as shown in FIG. 4A, the reservation recording method may display only the interface corresponding to the non-reservable program, that is, the baseball program 3 in red. Of course, at this time, the interface corresponding to the program other than the non-reservable program is preferably indexed other than red. The non-reservable program can be displayed differently from the reservable program and the remaining broadcast programs by using different images or icons, symbols, text, etc. in addition to the color.

In addition, as shown in FIG. 4B, the reservation recording method displays a reserved program, that is, an interface corresponding to the movie program 2 in blue, and an interface corresponding to the non-reservable program and the remaining programs other than blue. It may be displayed in a different color. Accordingly, the reserved recording method may display the reserved program differently from the non-reservable program and the remaining broadcast programs.

Accordingly, the reserved recording method according to the present invention can easily identify and determine information of broadcast programs capable of reserved recording and / or broadcast programs that cannot be reserved recording.

Referring back to FIG. 3, the user selects at least one first broadcast program from among a plurality of broadcast programs based on the recording confirmation information through the input device 17, or the user via the input device 17. By transmitting the first reserved recording information corresponding to the first broadcast program, a reservation recording of the first broadcast program to be reserved may be requested (S5).

Meanwhile, since the first broadcast program selected by the user is selected based on the recording confirmation information, the first broadcast program selected by the user may be a program capable of reservation recording, or may be a program that is impossible according to the user's selection. In such a case, the recording setup apparatus according to an exemplary embodiment of the present invention may provide information (ie, change information) about a solution in which the first broadcast program can be reserved.

To this end, the STB 13 may determine whether the first broadcast program is capable of reserved recording on the basis of the first reserved recording information and previously registered reserved recording information or the recording confirmation information (S7). ).

If the first broadcast program is any one of broadcast programs that cannot be reserved, the reserved recording information corresponding to the first broadcast program is not registered in the STB 13.

In addition, when the scheduled recording of the first broadcast program is impossible, the STB 13 may display, on the display apparatus 11, change information which is predetermined information for enabling reserved recording of the first broadcast program. There is (S9).

The change information is information including information for deleting or changing reservation recording information of at least one broadcast program among previously registered broadcast programs, and the user may enable reservation recording of the first broadcast program. It can contain all kinds of information that can be set.

In addition, the change information may be rebroadcast information of the first broadcast program or previously registered broadcast programs calculated based on EPG information received from an external (eg, broadcast station or Internet network), for example, broadcast schedule information. Of course, at this time, it is preferable that the EPG information includes information for distinguishing the main broadcast from rebroadcast.

In addition, the previously registered reserved recording information and the first reserved recording information corresponding to the first broadcast program are set in the STB 13 through different input devices 17, and If it is impossible to register, the STB 13 may provide a method of reserved recording of the first broadcast program while protecting previously registered reserved recording information input through another input device. That is, change information that can be set by the user to enable reserved recording of the first broadcast program, for example, information that can delete or change a broadcast program that has been previously reserved, has been excluded from the reserved recording list. Only rebroadcast information of the first broadcast program). Accordingly, the STB 13 can protect stored reserved recording information from another user's arbitrarily deleting or changing reserved registered recording information. In the case where reservation recording is not possible, the policy for the reservation recording program, which is preferentially protected, that is, the priority may vary depending on the implementation example such as the priority of the user and the priority according to the input order.

As a result, the reserved recording method according to the present invention can provide a solution to change / delete at least one reserved recording information among existing reserved recording information when the scheduled recording of the first broadcast program is impossible. .

For example, suppose that broadcast recording A and broadcast program B are set in common for a predetermined time period (hereinafter, not available for reservation recording). When the user requests a reservation recording confirmation request, the STB 13 may display information about a program including the reserved recording unavailable time or the reserved recording impossible time in a predetermined form. On the contrary, the STB 13 may display information about a program including the reserved recordable time or the reserved recordable time in a predetermined form. In addition, the scheduled recording method may simultaneously output information about a program including a time when a scheduled recording is impossible or the scheduled recordable time and information about a program including a scheduled recordable time or a program that includes the reserved recordable time. Can also be displayed.

However, the first broadcast program that the user wants to add the reserved recording may be a program including the non-reserved recording time. Then, the reserved recording method according to an embodiment of the present invention may provide the user with information for changing or deleting the reserved recording setting for the broadcast program A through a predetermined interface (for example, an OSD (On Screen Display)). have. Of course, the information for changing or deleting the reserved recording setting for the broadcast program B may be provided to the user through a predetermined interface (for example, an OSD (On Screen Display)).

In addition, the reservation recording method according to an embodiment of the present invention may provide a user with rebroadcast information of at least one of the broadcast program A, the broadcast program B, or the first broadcast program. The rebroadcast information may be retrieved from EPG information received from an external device (eg, a broadcasting station or an internet network) and stored in a predetermined storage device. Accordingly, the user may reserve the desired first broadcast program by changing or adding at least one re-broadcast program of the broadcast program A, the broadcast program B, or the first broadcast program to a reserved recording.

Of course, if the selected rebroadcast program is also a non-reservable program, the changed information may be provided to the user again.

When the user selects a method in which the first broadcast program can be reserved recording based on the change information provided in this way, the STB 13 performs a change process according to the selected method (S11), A reservation recording can be set (S13).

Meanwhile, when scheduled recording of the first broadcast program is possible, the set-top box 13 may store the first reserved recording information (S13).

5 is a flowchart illustrating an example of a reservation recording method according to an exemplary embodiment of the present invention. 6 is a diagram illustrating a reserved recording method according to an embodiment of the present invention. 7A and 7B are conceptual block diagrams in which a plurality of reserved recording information is stored according to an embodiment of the present invention.

5 to 7, when the user first selects a first broadcast program from among a plurality of broadcast programs, the input device 17 may include first reserved recording information for recording the first broadcast program, for example, a broadcast program. The title, channel, broadcast time, and the like may be transmitted to the STB 13 (S21). Then, the STB 13 may store the first reserved recording information and set a scheduled recording (S23).

Next, when the user selects a second broadcast program from among a plurality of broadcast programs, the input device 17 may transmit second reserved recording information corresponding to the second broadcast program to the STB 13. (S25).

The STB 13 determines whether the second broadcast program is capable of reserved recording on the basis of the first reserved recording information and the second reserved recording information, and when it is determined that the second broadcast program is scheduled recording. In operation S27, the second reserved recording information is stored and reserved recording is set.

For example, when the STB 13 has two tuners, at least two broadcast programs can be reserved recording regardless of the reserved recording information.

Thereafter, when the STB 13 receives a reservation recording confirmation request from the input device 17 (S29), in response to the reservation recording confirmation request, broadcast programs capable of / not scheduled recording and / or scheduled recording / not available Recording confirmation information including at least one of time information may be transmitted and displayed to the input device 17 or the display device 11 (S31 and S33).

For example, when the STB 13 has two tuners, the time when the scheduled recording is impossible is the first section t1 of FIG. 6 in which the first and second reserved recording information overlap each other. Impossible broadcast programs are broadcast programs in which the first section t1 overlaps at least a part of a broadcast time.

As described above, the reserved recording method may display the recording confirmation information calculated based on the existing reserved recording information before registering the reserved recording information of the broadcast program. Accordingly, the user can simply check whether the program he / she wants to reserve recording can be reserved, without comparing the information of the broadcast programs to be reserved.

When the user selects a third broadcast program from among a plurality of broadcast programs with reference to the recording confirmation information, the input device 17 sends the third reserved recording information corresponding to the third broadcast program to the STB 13. It transmits (S35).

The STB 13 may check whether reservation recording is possible based on the third reserved recording information, the first to second reserved recording information, and / or the recording confirmation information (S37).

As a result of the comparison, when the third broadcast program is one of the broadcast programs that cannot be reserved, the third reserved recording information of the third broadcast program cannot be registered in the STB 13.

Accordingly, when the scheduled recording of the third broadcast program is impossible, the STB 13 may change information including the selectable methods for storing the third reserved recording information of the third broadcast program. Or display on the display device 11 (S39 and S41).

For example, the change information may include at least one of deleting or changing the first reserved recording information, deleting or changing the second reserved recording information, or canceling the third reserved recording information.

In addition, the change information may be rebroadcast information of any one of the first to third reserved recording information based on the EPG information received from the outside (for example, a broadcasting station or the Internet network) and stored in the STB 13. have. That is, in the reserved recording method, at least one broadcast program among the broadcast programs to which the reserved recording information overlaps is set to be recorded at different time zones, thereby making the third broadcast program and the first to second broadcast programs impossible to reserve recording. You can record all of them.

The change information may be change information about a broadcast schedule for first to third reservation recording information and at least one reservation recording information for which reservation recording was previously canceled based on the received EPG information. That is, the reservation recording method may store reservation recording information for which reservation recording has been canceled, and when the reservation recording information that has been canceled due to a change in a broadcast schedule is possible to be registered, change information on the reservation recording may be displayed in real time.

The user changes the reserved recording information of any one of the first to third broadcast programs in response to the change information (S43).

As described above, the reserved recording method allows the user to easily display the changed information for changing the reserved recording information that has been registered in order to register the reserved recording information of the broadcast program when the third broadcast program cannot be reserved. It is effective to set scheduled recording information.

Further, when the third broadcast program is capable of reserved recording, the third reserved recording information may be in parallel with the reserved recording information in which the broadcast end time is close to the broadcast start time of the third broadcast program among the first and second reserved recording information. Is set. That is, a tuner unit used for reserved recording of the third broadcast program may be set.

For example, when the recording start time of the third broadcast program is close to the recording end time of the first broadcast program, the third reserved recording information is set in parallel with the first reserved recording information as shown in FIG. 7A. The first broadcast signal and the third broadcast signal are continuously received through the first tuner unit.

When the recording start time of the third broadcast program is close to the recording end time of the second broadcast program, as shown in FIG. 7B, the second broadcast is registered by registering the third reserved recording information side by side with the second reserved recording information. The signal and the third broadcast signal are continuously received through the second tuner unit.

Accordingly, the reservation recording method according to the present invention can secure a margin of a section in which reservation recording information of another broadcast program can be registered later.

The STB 13 may determine whether reservation recording is possible or not. For example, when there are two tuners of the STB 13 including the recording setting device, it may be determined by confirming whether three or more broadcast programs are registered at the same time based on newly input reserved recording information. In addition, if the method of generating the change information may also vary, it can be easily inferred that various implementations may exist to the average expert in the technical field of the present invention.

The reservation recording method according to an exemplary embodiment of the present invention may be implemented as computer readable codes on a computer readable recording medium. Computer-readable recording media include all kinds of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, hard disk, floppy disk, optical data storage, and the like, and also in the form of carrier waves (e.g., transmission over the Internet). It also includes implementations. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. And functional programs, codes and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.
