The present application claims the priority benefits of Korean Patent Application No. 10-2007-0049618 filed May 22, 2007 in Republic of Korea, which is incorporated by reference.
1. Field of Invention
The present invention relates to a method for displaying information of a recording material related to a program on broadcasting schedule information and an image display apparatus for implementing the method.
2. Discussion of the Background Art
Generally, a representative example of an image display apparatus includes a television (TV). The TV is an image display apparatus for selecting broadcasting signals transmitted through a channel selected by a user from broadcasting signals transmitted from a broadcasting station, demodulating the broadcasting signals, separating the broadcasting signals into voice signals and image signals, processing the voice signals and image signals, and outputting the voice signals through a speaker and displaying the image signal on the screen.
Generally, in the field of an image display apparatus, as TV technology develops, methods for transmitting broadcasting signals have developed, and accordingly, an interest in a digital TV that has applied digital transmission has increased.
The digital TV provides a function of allowing a user to store images in real-time using a personal video recorder (PVR) while viewing broadcasting and reproducing the stored images at a desired time, and this function can be used for recording a conference when a video conference is performed using a digital TV as well as for storing a favorite broadcasting program.
Generally, a PVR system is a personal digital video recording apparatus for recording/reproducing information on/from a hard disk drive (HDD). Unlike a video cassette recorder (VCR) for storing image signals on a magnetic tape, the PVR system is a digital recording apparatus of a new concept, for recording/reproducing information on/from an HDD. The PVR is a next generation recording apparatus that can record a broadcasting program of a predetermined time period depending on a capacity through an HDD mounted inside a set top box or a TV main body even without a VCR.
That is, the PVR system is a system that can convert digital broadcasting data (Europe: DVB, Korea/Japan/North America: ATSC), analog broadcasting data (Europe: PAL, Korea/Japan/North America: NTSC) received through a broadcasting channel into digital signals using a central processing unit (CPU) and a video signal processor, convert the digital signals into digital data and storing the same using a memory device inside the system to perform an analog-to-digital (A/D) conversion, and reproduce the stored digital data through a display device or a screen at a time or a method desired by a user in a TV system.
In a related art image display apparatus, however, a user cannot recognize whether or not a program on which the user has set a reservation recording is stored in the memory device for subsequent viewing. As a result, the user cannot view the corresponding program. Also, the user may unnecessarily record the same program (rebroadcast program) again even if the program is already stored in the memory device.
Also, in the case where the user sets a series reservation recording, all of the corresponding program series materials (including the rebroadcast program) are always recorded, so that already stored series materials may be doubly recorded unnecessarily.
The present invention is directed to providing an apparatus and method for managing materials to be reservation-recorded and controlling broadcast scheduling information, which address the limitations and disadvantages associated with the related art.
In one embodiment, an image display apparatus includes: a signal receiver for receiving broadcasting signals including broadcasting schedule information from an outside, and processing the received broadcasting signals; a storage for storing the broadcasting schedule information and a broadcasting program processed by the signal receiver; a user interface for receiving a request command from a user; a controller for judging whether recording materials related to a program existing in the broadcasting schedule information exist in the storage when a broadcasting schedule information display command is input from the user interface, and outputting a control signal so that the broadcasting schedule information including information regarding the recording material is displayed; and a broadcasting schedule information generator for generating broadcasting schedule information including recording material information related to at least one program in response to a control signal from the controller.
According to an embodiment, recording material state information related to programs on broadcasting schedule information is displayed, so that whether a desired recording material exists is recognized, viewing and deletion of the recording material can be managed. Since broadcasting schedule information including recording material information is displayed, a user can easily manage a recording material to make efficient use of a storage medium. Information of series recording materials related to a series program on broadcasting schedule information is displayed, so that a user can easily set series reservation recording. Already stored series recording material is not recorded again but immediately viewed. Also, reservation recording of only series program that overlaps already stored series material can be easily set.

According to an embodiment, a method for controlling an image display apparatus, comprises receiving a command for recording a series program, wherein the series program includes a plurality of episodes; determining if at least one episode of the series program is recorded in a storage unit; and displaying broadcasting schedule information including a list of the plurality of episodes if the determining step determines that all episodes of the series program are recorded, or displaying broadcasting schedule information including a menu for selecting at least one episode of the series program that is not recorded if the determining step determines that at least one episode of the series program is not recorded.
It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principle of the invention. In the drawings:
Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. In the present disclosure, a ‘recording material’ refers to any content or material (e.g., broadcasting material/content) which a user requests to be recorded/stored using an image display apparatus such as a PVR, and can include, but is not limited to, a program, advertisement, clip, audio, etc.
Referring to
The tuner 10 selects broadcasting signals of a channel desired by a user from broadcasting signals received from an outside, where the broadcast signal include broadcasting schedule information (e.g., electronic program guide (EPG)). The demodulator 20 demodulates the broadcasting signals selected by the tuner 10 to correct errors, and converts the broadcasting signals into transport streams (TSs). The demultiplexer 30 demultiplexes TSs input through the demodulator 20 and multiplexed in time to separate the TSs into voice streams, image streams, and additional information streams. The image signal processor 40 processes the image streams separated by the demultiplexer 30 so that the image streams can be displayed. The display 50 displays image signals processed by the image signal processor 40. The storage 60 stores broadcasting schedule information and broadcasting programs/materials. The user interface 70 receives request commands from a user, e.g., via a remote controller or other input unit.
When a broadcasting schedule information display command is input from the user interface 70, the controller 80 judges whether a recording material (e.g., program) identified in the broadcasting schedule information is already stored/recorded in the storage 60, and outputs a control signal based on the judgment result so that broadcasting schedule information including recording material state information related to at least one program/material is displayed. For example, the broadcasting schedule information generator 90 generates broadcasting schedule information including recording existence indicating information of the recording material in response to the control signal from the controller 80.
Also, the storage 60 includes a broadcasting schedule information memory 62 for storing broadcasting schedule information such as a program title, a program description, a broadcast time, etc.; a recording material storing memory 64 for storing a broadcasting program/material received from the outside, and a recording material list information memory 66 for storing list information of recording materials stored in the recording material storing memory 64.
The operation of the image display apparatus according to a first embodiment will be descried below.
First, when a power-on command is input through the user interface 70, the controller 80 outputs a signal so that broadcasting signals of a channel desired by a user are selected by the tuner 10.
The tuner 10 selects broadcasting signals of a channel desired by the user from broadcasting signals received from the outside, and the demodulator 20 demodulates the broadcasting signals selected by the tuner 10 to correct errors, and converts the broadcasting signals into TSs. The TSs output from the demodulator 20 and multiplexed in time are demultiplexed by the demultiplexer 30 and separated into audio streams, video/image streams, and additional information streams.
The image stream separated by the demultiplexer 30 is converted into a brightness signal and a color signal by the image signal processor 40, which are then displayed through the display 50. The image stream, audio/voice stream, and additional information stream separated by the demultiplexer 30 according to a recording command input through the user interface 70 pass through predetermined signal processings and are stored in the storage 60.
Here, the additional information stream preferably means additional information (e.g., a program title, a broadcasting time, a channel, and a genre, etc.) regarding a program/material to be broadcast in the future by a predetermined period. The additional information is stored in the broadcasting schedule information memory 62 in response to a control signal of the controller 80. The image and voice streams are stored in the recording material storing memory 64. List information of programs/material stored in the recording material storing memory 64 is stored in the recording material list information memory 66, and can identify a list of materials that are stored/recorded in the memory 64. Then a user can view this list to know what materials are already recorded so duplicate recording of broadcast programs can be avoided in an efficient manner. Also, when a broadcasting schedule information display command is input from the user interface 70, the controller 80 extracts a corresponding broadcasting schedule information from the broadcasting schedule information memory 62, and judges whether a recording material related to a program identified in the broadcasting schedule information is already stored in the recording material list information memory 66.
For example, information regarding programs to be broadcast in the future and programs broadcasted previously can be part of the broadcasting schedule information. A program title contained in the broadcasting schedule information is compared with a recording list stored in the recording material information memory 66 to judge whether a recording material related to the program is stored in the recording material storing memory 66.
Here, the recording material related to the program preferably means the program itself, or any part of the program (e.g., at least one episode) in case of a series program.
That is, the controller 80 outputs a control signal so that when a general program contained in the broadcasting schedule information is rebroadcasting and a corresponding recording material exists in the memory 64 (i.e., the broadcast program is already stored in the memory 64 per user's request, recording existence indicating information of the stored recording material is displayed on the display 50. When the general program contained in the broadcasting schedule information is a series program and the series program is already stored in the memory 64, broadcasting schedule information modified to include the recording existence indicating information of the series program is displayed on the display 50.
The broadcasting schedule information generator 90 generates the modified broadcasting schedule information including the recording existence indicating information of a recording material/program on the basis of information regarding whether the recording material is stored in the memory 64 in response to a control signal of the controller 80.
The image signal processor 40 mixes an image stream separated by the demultiplexer 30 and the broadcasting schedule information generated by the broadcasting schedule information generator 90 to perform signal processing so that the image signal (image stream) can be displayed. The display 50 receives the signal-processed image signal and displays the same.
A method for controlling the image display apparatus according to a first embodiment is discussed now referring to
Referring to
Subsequently, when the broadcasting schedule information display command is input as a result of the judgment (S101), broadcasting schedule information already stored in the broadcasting schedule information memory 62 is read (S102).
Regarding a first program identified in the broadcast schedule information, whether the first program (recording material) exists in the recording material storing memory 64 is judged (S103-S104). For example, a title (or some other identification) of the first program is compared with a recording list already stored in the recording material information memory 66 to judge whether the first program is included in the stored recording list. If the title of the first program is included in the stored recording list as being recorded, then the first program is determined to be stored in the memory 64. Other parameters such as program ID may be used to determine if a particular program is listed in the stored recording list. Here, the recording material can be the entire program or part of the program, where the program can have multiple episodes or series. Subsequently, when the particular recording material (program) is determined to exist in the memory 64 as a result of the judgment (S104), recording existence indicating information (“State Information”) of that program is set to 1 (S105). In this example, setting the recording existence indicating information (“State Information”) to 1 means that the corresponding program exists (is stored) in the recording material storing memory 64, and to 0 means that the corresponding program does not exist in the recording material storing memory 64.
When it is determined that the corresponding recording material (program) does not exist in the memory 64 as a result of the judgment (S104), the recording existence indicating information of the program is set to 0 (S106). Then whether the program is a last program identified in the broadcasting schedule information is judged (S107).
Subsequently, if the program is not the last program, then a next program identified in the broadcasting schedule information is judged according to step S104 (S108). That is, when the current program is an n-th program at step S107, step S104 is performed on an (n+1)-th program to check whether the (n+1)-th program is stored in the memory 64. Through steps S104-S108, all the programs identified in the broadcasting schedule information are checked to determine if they are stored in the memory 64.
Also, when it is determined that the current program is the last program identified in the broadcasting schedule information as a result of the judgment (S107), broadcasting schedule information (e.g., EPG information) having recording existence indicating information (e.g., symbol 110 in
Description of an image display apparatus according to another embodiment is made for parts different from those of the previous embodiment, and the description of the same parts is omitted or briefly discussed.
The image display apparatus according to this embodiment includes a tuner 10, a demodulator 20, a demultiplexer 30, an image signal processor 40, a display 50, a storage 60, a user interface 70, a controller 80, and a broadcasting schedule information generator 90. These components are discussed also above in connection with
When a broadcasting schedule information display command is input from the user interface 70, the controller 80 checks whether a series recording material (e.g., a series program or program with multiple episodes) identified in the broadcasting schedule information exists (is stored) in the recording material storing memory 64, and outputs a control signal accordingly so that the broadcasting schedule information including recording existence indicating information of the series recording material is displayed on the display 50. The broadcasting schedule information generator 90 generates the broadcasting schedule information including the recording existence indicating information of the series recording material in response to a control signal of the controller 80.
The operation of the image display apparatus according to another embodiment will be descried below.
First, when a broadcasting schedule information display command is input from the user interface 70, the controller 80 reads broadcasting schedule information stored in the broadcasting schedule information memory 62, and judges whether a series recording material exists with respect to only series programs identified in the broadcasting schedule information.
For example, the controller 80 reads the broadcasting schedule information, judges whether a particular program is a series program using additional information regarding programs identified in the broadcasting schedule information, and then judges whether the series program exists in the memory 64 with.
Also, the controller 80 sets recording existence indicating information of a series recording material (e.g., series program) to, e.g., 1, which indicates that this series recording material is not already stored in the memory 64 and that the user can request this series recording material to be recorded in the image display apparatus if desired. Also, if a particular series recording material exists in the memory 64, the controller 80 judges whether the corresponding series recording material exists in its entirety or partially.
For example, the controller 80 judges whether all series (or episodes) of the series program exist in the memory 64, some of the series of the series program exist in the memory 64, or none of the series of the series program exist in the memory 64t. Whether the series recording material exists in its entirety or partially can be checked, e.g., using the recording material list information already stored in the recording material list information memory 66.
Also, if the series recording material exists in its entirety (i.e., all series/episodes are stored in the memory 64), the controller 80 sets the recording existence indicating information of the series program to, e.g., 2. When the series recording material exists partially (i.e., only some of the series/episodes are stored in the memory 64), the controller 80 sets the recording existence indicating information of the series program to, e.g., 3. Other values may be used for the recording existence indicating information.
Also, the controller 80 judges whether a reservation recording has been already set with respect to the series program. For example, the controller 80 compares the series program with reservation recording list information (e.g., stored in the image display apparatus) to judge whether there the reservation recording is set for the series program.
Therefore, if a reservation recording has been already set (requested by the user) for the particular series program, the controller 80 sets reservation recording set state information of the series program to, e.g., A or some other value. If, however, a reservation recording is not set for the particular series program, the controller 80 sets the reservation recording set state information of the series program to, e.g., B or some other value, so that such information can be used to indicate to the user whether or not a reservation recording for a particular program has been requested/set by the user.
Also, the controller 80 delivers recording existence indicating information (e.g., state information 210, 220, 230 in
Referring to
Also, state information 240 representing whether a reservation recording has been set for the program can be displayed on the series programs. For example, “REC” (state information 240) is displayed next to the series program “Dae Joyoung” to indicate that a reservation recording has been set for this program. Thus those episodes of the program “Dae Joyoung” that are not already stored in the memory 64 will be stored in the memory 64. That is, wherever “REC” is displayed, it means that the user has requested a recording of the entire series program (if none is already recorded) or a recording of any part of the series program which is not recorded into the memory 64. Also, when a user inputs a series reservation set command regarding a series program whose episodes partially exist in the memory 64 using the displayed recording material state information, the controller 80 guides recording such that the recording is performed for only the remaining not-recorded episodes, so as not to overlap with the already stored episodes of the series recording materials. As a result, the present invention prevents duplicate recording of same materials in the storage 60.
Though the recording existence indicating information (e.g., 210, 220, 230) representing whether a recording material exists in the memory 64, and the reservation recording set state information (e.g., 240) are separately displayed on the broadcasting schedule information according to an embodiment, the reservation recording set state information can be included in the recording existence indicating information and displayed.
Referring to
Subsequently, when the broadcasting schedule information display command is input as a result of the judgment (S201), already stored guide information (e.g., EPG) is read from the memory 62 (S202).
Then it is determined (e.g., by the controller 80) whether or not a first program identified in the program guide information is a series program (S203-S204).
Subsequently, when it is determined (e.g., by the controller 80) that the current program is a series program as the result of the judgment (S204), it is determined whether there exist, in the recording list stored in the memory 66, any series recording materials related to the current series program (S205). As discussed above, the recording material related to the program preferably means the program itself, but can mean other materials associated with the program.
If there do not exist the related series recording materials as a result of the judgment (S205), recording existence indicating information of the program is set to, e.g., 1 (S206). This represents that the series reservation recording of the series program can be set by the user if desired since this program is not stored in the memory 64 at all.
If there exist the related series recording materials as a result of the judgment (S205), it is determined all of the series recording materials (e.g., all episodes or series of the program) exists in the memory 64 (S207).
Subsequently, if there exist all of the series recording materials as a result of the judgment (S207), recording existence indicating information of the program is set to, e.g., 2 (S208). This represents that there exist the series recording materials of the series program corresponding to all episodes.
If there exist only part of the series recording materials as a result of the judgment (S207), recording existence indicating information of the program is set to, e.g., 3 (S209). This represents that the series program has been recorded for only some of the episodes.
Also, whether a reservation recording has been set for the series program is judged (S210).
Subsequently, if the reservation recording has been set for the series program as a result of the judgment (S210), reservation recording set state information of the series program is set to, e.g., A (S211). When the reservation recording has not been set for the series program as a result of the judgment (S210), reservation recording set state information of the series program is set to, e.g., B (S212).
Then whether the program is a last program identified in the broadcasting schedule program is judged (S213).
Subsequently, when the currently considered program is not the last program as a result of the judgment (S213), a next program identified in the broadcasting schedule program is judged (S214). That is, when the current program is an n-th program, step S204 is performed on an (n+1)-th program to check a recording material exist state and reservation recording set state with respect to the program. This process is repeated for each program identified in the broadcasting schedule program.
If the current program is the last program identified in the broadcasting schedule information as a result of the judgment (S213), modified broadcasting schedule information having at least one indicator indicating the recording existence indicating information and the reservation recording set state information is generated for display (S215).
As described above, an image display apparatus and a method for controlling the same according to the second embodiment display recording existence indicating information and reservation recording state information on the broadcasting schedule information, thereby allowing a user to easily set and manage series recording and view already stored series recording materials easily.
Description of an image display apparatus according to still another embodiment is made for parts different from those of the previous embodiments, and the description of the same parts is omitted or may be briefly discussed.
That is, the operation of the image display apparatus according to the third embodiment will be described below.
First, when a broadcasting schedule information display command is input from the user interface 70, the controller 80 reads broadcasting schedule information stored in the broadcasting schedule information memory 62, and the broadcasting schedule information generator 90 generates broadcasting schedule information in response to a control signal of the controller 80.
When a series reservation command is received on the broadcasting schedule information, the controller 80 searches for a recording material list stored in the recording material list information memory 66 to judge whether series recording materials related to a series program for which a user desires to set the series reservation recording are already stored in the memory 64.
Subsequently, if the controller 80 determines that the series recording materials related to the series program do not exist in the memory 64 as a result of the searching of the recording material list, the controller 80 controls setting of the series reservation recording of the series program according to the user's request.
On the other hand, if the controller 80 determines that the series recording materials related to the series program exist (are stored) in the memory 64 as a result of the searching of the recording material list, the controller 80 checks whether the series recording materials exist in the memory 64 in their entirety, or partially.
If the series recording materials exist in their entirety in the memory 64, a message informing that the serial materials exist in their entirety in the recording material storing memory 64 is displayed to the user, and a recording list regarding the stored series recording materials is displayed to allow the user to immediately select and view the already stored series recording materials without setting a reservation recording of the series program.
As an example, referring to
Also, when the series recording materials exist partially in the memory 64 (e.g., only certain episodes of a series program are stored in the memory 64), the controller 80 guides the user by providing appropriate menu(s) such that a series reservation recording can set selectively for only those non-stored series materials, excluding the already stored series recording materials of the program.
As an example, referring to
In other words, the setting guidance menu 400 allows the user to set the series reservation recording only for the remaining non-stored episodes of the series program, excluding the already stored episodes of the series program, Here, it preferable that the episodes that are already stored in the memory 64 are shown as inactivated (not selectable by the user) and the episodes that are not stored in the memory 64 are shown as activated (selectable by the user) in the list of the setting guidance menu 400. For example, as shown in
In an example, if the controller 80 determines that all the episodes of a requested series program are already recorded in the memory 64, then the broadcasting schedule information as shown in
Further, the various embodiments of the invention may be combined. For example, some of the features of the second and third embodiments may be combined such that in
Referring to
Subsequently, whether a series reservation recording command is input is judged on the broadcasting schedule information (S302).
If it is determined that the series reservation recording command is input as a result of the judgment (S302), series recording materials related to a program for which the user desires to set the series reservation recording are searched for on a list of stored recording materials, e.g., from the list stored in the memory 66 (S303). Subsequently, whether there exist, in the memory 64, the series recording materials related to the program for which the user desires to set the series reservation recording is judged (S304).
If it is determined that there exist the series recording materials in the memory 64 as a result of the judgment (S304), the controller 80 determines whether the series recording materials (series program) exist in their entirety or partially (S305).
If it is determined that the series recording materials exist in their entirety in the memory 64 as a result of the judgment (S305), a message informing that the series recording materials related to the desired program for which the user desires to set the series reservation recording are already stored in the memory 64 in their entirety is displayed to the user (S308-S309). Further, the list of the stored recording materials as shown in
If it is determined that the series recording materials exist partially in the memory 64 as a result of the judgment (S305), a list of the related series recording materials is displayed, e.g., as shown in
Also, the controller 80 guides the user such that a reservation recording is set for only the remaining non-stored episodes excluding the already stored series recording materials, e.g., as shown in
Subsequently, when a remaining episode reservation set command is received from the user, the series reservation recording is set for only the episodes selected by the user (S312-S313).
Also, a corresponding reservation recording set state is displayed on the broadcasting schedule information of the program for which the series reservation recording has been set (S314). For example, ‘REC’ may be shown next to that program in the displayed EPG.
On the other hand, if it is determined that the series recording materials related to the corresponding program do not exist in the memory 64 at all as a result of the judgment (S304), the series reservation recording of the entire program is set (S315).
Also, a corresponding reservation recording set state is displayed on broadcasting schedule information of the program for which the series recording has been set (S316). In this case, ‘REC’ may be shown next to the program in the displayed EPG.
As described above, an image display apparatus and a method for controlling the same according to this embodiment judge whether there exist series recording materials related to a program for which a user desires so as to set series reservation recording. The invention also guides the user so that the series recording materials are immediately reproduced without going through the process of setting reservation recording of the program, when the series recording materials exist in their entirety in the memory 64, and guides the user so that the series reservation recording is set for only the remaining non-stored episodes excluding the already stored series recording materials, thereby allowing the user to easily and efficiently set the series reservation recording.
The present invention can be used in any device in which broadcasting content can be recorded and reproduced.
According to the embodiments, a user can check recording material information in broadcasting schedule information at one glance to easily view and delete the recording materials in an efficient manner. This results in a user-friendly system for reservation-recording broadcast contents and managing the reservation-recorded broadcast contents.
Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure.
