In particular, the program reservation method of the digital TV according to the present invention relates to a program reservation method for detecting from a program guide information based on an item selected by a user and storing the same in a selected category.

As digital broadcasting begins, various types of digital broadcasting receivers (DTV: Direct View DTV, DTV set-top box, etc.) are being developed and marketed. The digital broadcast receiver is provided with a PSIP (Program and System Information Protocol) standard, so that guide information (EPG; Electronic Program Guide) for a broadcast or scheduled program is transmitted to the receiver.

Program guide information in the ATSC (Advanced Television Standards Committee) / PSIP specification, which is a digital broadcasting standard in the United States, mainly includes information such as program start time, content summary, and rating. In addition, the program guide information of KBPS (Korean Broadcasting Program System), a domestic analog broadcasting standard, includes information such as a start time of a program, a summary of contents, a rating, and a program category.

As such, when a broadcasting station transmits video and audio signals and related information about programs to be broadcast for a certain period of time, the receiver may process and store such information to provide information to the user in various forms. Can be. Therefore, the user can obtain information such as title, rating, time, channel, etc. related to programs to be broadcast for a certain time (for example, 3 to 7 days). Able to know.

At present, many conventional digital broadcasting receivers use this to provide a user with information related to a program to be broadcasted within a certain period of time, and to provide a function for reserving a viewing if the program is of interest to the user. .

That is, data broadcasting is transmitted by multiplexing the information in the vertical retrace period of the TV video signal or by using a separate channel for character information, still image, product information, program guide (EPG: Electronic Program Guide) for general TV or PC holders. Is a new media service that provides multimedia content.

In a conventional receiver receiving such a data broadcast, when a program for which reserved viewing has been performed is broadcasted, the user is notified that the program for which the reservation has been set is broadcast to the user a predetermined time (for example, 5 minutes) or the program is broadcasted. At the point of time, the program moves to the channel where the program is broadcasted so that the user misses watching the program.

To this end, a user manipulates a program guide to determine whether there is a preference with various information that follows each individual program among programs broadcast for a certain period of time, and reserves only the preferred program through a separate input.

However, in the conventional digital broadcasting receiver, in order to reserve a program of interest to the user, the program must be within the range of use provided, so that the program is searched for each time. There is a problem that needs to be set, and because the setting of a program must always be done on a program-by-program basis, there is a problem that a reservation must be set every time when one or more programs having a similar item are interested by the user.

In addition, there is a problem that a user cannot make a reservation for a program for which information is not provided within a time range provided by a current program.

In the case of a Video On Demand (VOD) program, broadcasts occur continuously within a predetermined period of time and with different channels. In the case of such a broadcast, when a simple reservation system is configured, a user frequently informs that a corresponding program is reserved.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and a program having a reservation item set by the user at any time by setting a reservation item at a time by using information of an item and a string among information related to a broadcast program is provided. It is an object of the present invention to provide a program reservation method of a digital broadcast receiver that allows a user to make a reservation more conveniently and to watch the program by automatically notifying the user by positioning when broadcast.

Program reservation method of the digital broadcast receiver according to the present invention for achieving the above object,

Setting selection criteria information of a program selected by the user by providing a reservation setting window to the user;

Detecting broadcast program guide information;

Comparing the set program selection criterion information with the broadcast program guide information detected by the detected program and detecting a program having matching guide information;

If the schedule program is detected, newly changing and storing the reservation program within a reservation category set by a user;

If the reserved program is broadcasted, characterized in that it comprises the step of automatically informing the corresponding time by the positioning set by the user.

Herein, the reservation setting window may include: an OSD keyboard for inputting a specific string corresponding to a specific item among items provided in the item list, a list of items and items that allow a user to set a specific item, and And an input result window for displaying an input result of the keyboard.

Hereinafter, with reference to the accompanying drawings as follows. 1 is a configuration diagram of a digital broadcast receiver, FIG. 2 is an analog broadcast receiver, FIG. 3 is a diagram illustrating an example of a program guide, FIG. 4 is a diagram illustrating a program reservation setting window, and FIG. 5 is a program information positioning. 6 is a flowchart illustrating a program information positioning OSD.

First, a configuration of a broadcast receiver for implementing a program reservation method of a broadcast receiver according to the present invention will be described with reference to FIG. 1.

The broadcast receiver according to the present invention includes a tuner 10 for receiving audio, video and program related broadcast data together, and an A / D demodulator 20 for digitizing the received broadcast data and outputting a transport stream 30. ), An audio decoder 31 for decoding an audio signal according to the data type of the transport stream 30, a video decoder 32 for decoding a video signal according to the data type of the transport stream 30, and Data parser 33 which receives data of transport stream 30 and classifies related information such as start time, duration, rating information, genre, etc. of program, and processes video signal decoded by video decoder 31. The video processor 40, the audio device 41 for outputting the audio signal decoded by the audio decoder 32, and the video signal processed by the video processor 40 And to display the video device 42, according to the schedule information preset by the user controls the video processor 40 and is configured to include a system controller 50 for storing the program information classification from the data parser 33 .

The system controller 50 may include a first memory (RAM) 51 storing program information classified by the data parser 33, a second memory (ROM) 52 storing an initially set program, and the first memory. And a microcomputer 53 for controlling the video processor 40 using information stored in the second memories 51 and 52, an OSD (On Screen Display) processor 54 for OSD processing by the microcomputer 53; And a database 55.

2 is a schematic structural diagram of an analog broadcast receiver, and the same reference numerals will be used for the same parts as the digital broadcast receiver.

Tuner 10 and the video signal of the VBI (Vertical Blanking Interval), VBI detector 70, which detects the broadcast information contained in the interval received, classify the broadcast information detected by the VBI detector 70. The system controller (50 It is composed of a VBI data parser 71 to be applied to.

A program reservation method for a digital broadcast receiver according to the present invention configured as described above will be described with reference to the accompanying drawings.

First, when the transmitting side transmits audio, video, and program related data, the signal receives audio, video, and data signals through the tuner 10 of the receiver, and the received signal is transmitted to the A / D demodulator 20. Is digitized to become the transport stream 30.

The transport stream 30 is input to the audio decoder 31 and the video decoder 32 according to the type of data, and then decoded into an audio signal and a video signal, respectively, which decodes the video processor 40. Is output by the video device 42 and the decoded audio signal is output by the audio device 41.

The data parser 33 receiving the transport stream 30 classifies information such as a start time, a duration, a rating information, a genre of a program, and information related to a program of an item and a string, and controls the system. The first memory (RAM) 51 of 50 is stored.

At this time, the information stored in the first memory 51 of the system control unit 50 is provided by the microcomputer 52 as a database of a routine for operating a program guide, a reservation system, etc. stored in the second memory 53. The information on the reservation item set by the user is stored in the second memory 53 and is always stored even when the system is turned off.

In addition, the OSD processing unit 54 provides a user interface setting and a program posting through the OSD, and the database 55 stores data required for program posting .

The microcomputer 52 of the system controller 50 compares the program-related data stored in the first memory 51 when necessary by using the reservation system routine stored in the second memory 53 and the reservation item list set by the user. Reservation will be made through.

On the other hand, Figure 2 is a system configuration when applied to a receiver for receiving an analog signal in the digital broadcast reception, when the transmitting side is loaded with the program-related information on the VBI line along with the signal associated with the current broadcast tuner 10 Receives this, the audio signal of the received signal is output to the audio device 41, the video signal to the video device 42 through the video processor 40.

In order to detect the program related information, the VBI detection unit 70 receives a video signal and detects information contained in the VBI line, and the information contained in the detected VBI line is started by the VBI data parser 71. Information such as time, duration, rating information, genre and the like and information related to a program of the item string are detected and stored in the first memory 51 of the system controller 50. Using this information, the system controller 50 performs the reservation operation as described above.

The program guide (EPG, 100) of such data broadcasting is detected as shown in FIG. 3, and when the user sets an item of interest only once, each channel (CH11 / CH12) is automatically regardless of the time (Time1, Time 2 ..). / ..) for the program (PRG11, PRG12, PRG13 / PRG21 / ..) comparison will automatically set the reservation unless the setting is changed.

To this end, the present invention provides a reservation setting window 110 as shown in Figure 4, the reservation setting window 110, the reservation item 111 and its item list 112, keyboard 113, input result window 114 Into four subdivisions, these are reservation tools for the user to set a reservation item.

The user-defined reservation item 111 may have a maximum of n (Reserve 1 to Reserve n). That is, when a user sets a specific item, they can be stored in each item and set a reservation up to n.

To this end, the user selects one of the items provided in the item lists (Item1 to Itemk) 112, and the types of the items are largely movies, sports, music, dramas, and the like. In the case of a film, the main actor, the supporting actor, the director, etc., can be subdivided into team names, participating players, etc. The actor's name, which is a simple string in the list of items, must be associated with the item to make a more accurate reservation.

In addition, the keyboard 113 enables a user to input a specific character string of the selected item list 112 by using an OSD-type key signal (eg, A to Z) by the OSD processing unit 54. The result of the input is immediately shown to the user through the input result window 114, it is possible to modify, change the preset reservation items.

In this way, the contents of the individual reserved item set in the reserved item 111 and the item list 112 and the individual program related information transmitted from the broadcasting station are compared to determine whether the item matches the corresponding item. If the current comparison program matches the specific condition of the reservation item, the program is stored in the reservation list and automatically provided to the user at the corresponding time.

Here, since these items are criteria for setting a reservation, they should be provided from a broadcasting station before the user sets a reservation, and a certain level of standardization should be made to prevent frequent changes.

When the program reservation method using the reservation setting window 110 is described in detail, the user selects a movie from the item 111, selects the "star actor" item from the item list 112, and then uses the keyboard 113. When a particular actor is set by inputting a name of a specific actor, it is displayed in the input result window 114 and the result is stored in one of the reservation item list 111. These are continuously stored in the second memory 153 unless the user deletes or changes the corresponding correction item.

That is, the content of the reserved item stored in the second memory 53 is a specific item (star actor) and the name of the star actor ("Tom Hanks"), so that the information is <star actor, Tom Hanks> at a specific time. If a program having is detected, this information is extracted and compared with one of the reservation items. As a result of this comparison, the program is automatically matched to one of the preset reservation items, and the program is automatically added to the reservation list, and the user is automatically tuned to the corresponding broadcast time or the user is notified that the program is started before the scheduled time.

In the case of a Video On Demand (VOD) program, when broadcasting is continuously performed within a certain period of time or at different channels, or when the same program appears several times, it is determined whether they are VOD programs. Do not provide it.

In other words, if the program appears in a different channel or time for a certain period of time (eg 1 day), it is recognized as a VOD program and only once for the program that appears within the closest time based on the time when the reservation system is applied. Providing a reservation watching message to the user, if the user watches the reservation, the title of this program is stored for a certain period of time, and if the same program is subsequently displayed, this information is used to confirm that the viewer has already watched the program. Does not provide reservation viewing.

The viewing discrimination information of the VOD program is automatically maintained after a certain period of time (eg, 7 days) is passed.

However, when the viewer makes an input that the viewer does not watch in the viewing discrimination information of the VOD program, the reservation system ignores the current program and repeats the above-described process for the next appearing program.

If it is a daily play, it appears once a day, so it is not a VOD program. Therefore, in this case, it is generally handled as not always watching.

On the other hand, the post or alarm for notifying the user about the above-described reservation items briefly described as follows.

FIG. 5 shows an example of a menu for setting a program information posting (Posting or Alarm) function. The viewer sets a desired condition in a menu for setting this function when a program is required for posting .

To this end, one or more of the conditions for searching for a desired condition in an item of the database 55 processed with program guide information (Program title, contents, category, etc.) among the user settings. To select.

In this way, when the user selects an item, the user sets a posting condition among the items, and if the condition (eg a word) is matched, the condition can be positioned in the item's database. That is, if the program title is selected from the processed database and the word input is entered as "love", the word "love" is included in the title to be posted (or alarm).

In addition, as described above, when the user selects a sport by providing a menu exemplified in advance, that is, a sports, a drama, or a movie, the posting includes a word related to the program in advance. Finding the posting target program.

Then, the post time setting, if it finds a program that meets the above-mentioned post conditions will be posted with a certain amount of time from the start time of the program, with a certain time interval will be continued post, or continuously to posting It is to input the condition such as whether it is.

The OSD posting setting provides a user interface setting menu so that the OSD position can be displayed on any one of "Posting Ex A, B, C, D" through the OSD processing unit 54 when posting . The OSD then informs the viewer. It also provides automatic channel switching with a posting program in the setting menu.

A detailed description when the viewer's favorite sport has set me to post in, if it is determined that sports in all conditions, input (data collected base) program start time 5 minutes later, when determining the viewer whether or not to be postings Program do.

As described above, according to the program reservation method of the digital broadcasting receiver according to the present invention, a program having a reservation item is broadcasted by the user once setting the reservation item by using information of an item and a string among information related to the program. In this case, the user is automatically notified so that the user can watch the program more conveniently. In addition, when there are more than one similar program, the reservation is automatically made at the same time with one setting.

In addition, by building a database using a variety of program information sent from the broadcasting station, by providing a program posting so that the user can not miss the desired program by receiving the appropriate selection of the user, there is an effect to provide convenience to the user.
