Description

Method for reservation visual in digital TV

The present invention relates to an update method for changing a schedule of a reserved viewing program registered in a digital TV.

Digital TV broadcasting is being provided in earnest by each broadcasting company. Digital broadcasting provides a lot more channels than conventional analogues, so the number of programs provided by broadcasting stations is quite large.

For this reason, digital TV broadcasting provides an EPG (Electronic Program Guide) to provide convenience to the user.

In domestic analog broadcasting, KBPS (Korea Broadcasting Program System) is used to transmit information using the VBI (Vertical Blanking Interval) section, and digital broadcasting uses PSIP (Program and System Information Protocol) information. .

In the US, DirecTV broadcasts use EPG (Automatic Priority Group) to implement EPG. The user may know the broadcast program schedule through the EPG, and may register the reserved program as a reserved viewing for the program to be broadcasted in time, and watch the program he / she wants to watch in time.

In such an EPG, a program desired by a user is registered in the reserved viewing by using the start time and channel of the program.

1 is a view showing an embodiment of a registration registration and EPG according to the prior art.

In this way, the user selects a program he / she wants to watch in the provided EPG, and if the selected program is a program that is currently being broadcast, tunes to the channel being broadcast.

If the program is a program to be broadcasted in the future, that is, in the future, an information window appears asking the user whether to register in the reserved viewing list. If the user selects to register in the reserved viewing list, the program is registered as reserved viewing.

The start time, channel and program title of the program are extracted from the EPG and stored together in the reserved viewing list storing the registered program.

After that, the processor looks at the timer and if the start time is the same as the program in the reserved watch list, an information window appears asking whether to tune to the channel on which the program is being broadcast.

2 is a diagram illustrating a flowchart of registering a selected program according to the related art to a reserved viewing list and actually viewing the same.

As shown in FIG. 2, a user first selects a plurality of programs to be watched by searching an EPG provided on a screen (S10).

Then, the processor determines whether the program selected by the user is a program that is currently being broadcast (S20).

As a result of the determination (S20), in the case of a program that is currently being broadcast, it is converted to a corresponding channel so that the user can view it (S70).

When the selected program is not a program that is currently being broadcast, the determination result (S20) provides a user with an information window according to the reserved viewing to determine whether to reserve the selected program (S30).

If it is determined that the selected program is not reserved for the selected program (S30), the next program is selected (S10), and if it is determined that the selected program is reserved for the selected program (S30), the start time and channel number of the selected program are determined. And a timer and the like are recorded in the reserved viewing list (S40).

Then, the start time of the selected program is compared with the time of the current system through the operation of the timer (S50) (S60).

When the comparison time (S60) and the start time and the current system time is the same time, the channel is changed to a channel according to the corresponding program so that the user can view it (S70).

However, in the above-described conventional method for digital TV reservation viewing, when a broadcast schedule is changed due to a situation of a broadcasting station or a special event, that is, a registered program is canceled and another program is broadcasted or a start time change or channel is changed. If changed, all reserved reservation lists reserved by the user become obsolete, and the user is inconvenient to prepare a reserved viewing list again from the beginning.

Accordingly, the viewer may be changed until the program cannot be viewed because the program reserved for viewing is changed for the above reason.

Accordingly, the present invention has been made to solve the above problems, and when the broadcast schedule of a program registered by the user is changed, the viewer is notified of the changed contents, thereby causing a disadvantage in that the viewer changes the broadcast schedule. The purpose of the present invention is to provide a digital TV reservation viewing method.

3 is a flowchart illustrating a method for updating a reserved viewing list according to the present invention.

4A to 4B illustrate examples of an interface for notifying a user when updating a reserved viewing list according to the present invention.

A feature of the digital TV reservation viewing method according to the present invention for achieving the above object is to configure a reservation viewing list that the user wants to watch using the received EPG, the configured reservation viewing list and the received guide update list The first determination step of determining whether there is a program of the same title by comparing the same, and the second determination step of determining whether the start time of the corresponding program and the broadcast channel number are the same when it is determined that there is a program of the same title. And if the start time or the broadcast channel or both are not the same as the result of the second determination, the reservation information is transmitted after confirming whether the update is made by transmitting the contents to be modified among the information of the corresponding program in the guide update list to the viewer. Updating the program in the watch list and the first determination result. If it is determined that there is no program of the same title, a third judging step of judging whether a program having the same broadcast channel number as the guide update list is in the reservation viewing list, and if there is a program having the same channel number as the third judgment result, The fourth determination step of determining whether the same broadcast start time, and if there is a program having the same broadcast start time as a result of the fourth determination, after confirming whether or not to update the contents to be modified in the reserved watch list to confirm the update, Updating the corresponding program in the viewing list and comparing the time-duration of each program in the guide update list with the reserved viewing list if there is no program having the same broadcast start time as a result of the fourth determination. A fifth determination step of determining whether there is an area, and the fifth determination result If there are overlapping airtimes, the contents of the reserved viewing list are delivered to the user to confirm whether they are updated, and then the corresponding program is updated in the reservation viewing list.

In this case, the reserved viewing list includes at least one or more of a channel of the program, a start time, a time-duration, and program related information.

In this case, the reservation viewing list update may include informing the viewer of the change through an information window indicating the change of the change when the broadcasting channel or the start time of a certain program is changed, and checking whether the viewer is registered in the reserved watch list. When the viewer confirms with the registration, the viewer may be notified that the corresponding program has been updated, and confirming whether the updated program has been registered in the reserved viewing list.

According to an aspect of the present invention, when the broadcast guide information, which is EPG, is updated, this information is compared with the reserved viewing list registered by the user, and the user is notified of the contents to be updated and applied to the reserved viewing list, so that Provide convenience to city hall.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

A preferred embodiment of the DTV reservation watching method according to the present invention will be described with reference to the accompanying drawings.

3 is a flowchart illustrating a reservation viewing list updating method according to the present invention.

Referring to FIG. 3, first, a viewer constructs a reservation view list that he or she wants to view using an EPG received as a broadcast signal through the method as shown in FIG. 2.

In this case, the reserved viewing list stores a channel of the program, a start time, a broadcast time-duration of the program, and program related information.

Subsequently, when the guide update list is received from the EPG information, the guide update list is compared with the reservation request list to determine whether the reservation request list is updated (S100).

In this case, the reservation viewing list is updated can be classified into four types as follows.

When the start time of the program is changed, when the broadcast channel of the program is changed, when both the start time and the channel are changed, and may be replaced by another program.

First, as a result of comparing the reservation viewing list with the guide update list, it is determined whether there is a program of the same title (S200).

If it is determined in step S200 that there are programs of the same title, it is determined whether a start time and a broadcast channel number of each program are the same (S300).

If the start time is the same as the result of the determination (S300), it is determined that there is no content to be updated (S800). If the start time is not the same, the updated title of the guide has the same title as the program registered in the reserved viewing list. After searching for the program, the contents of the program having the same title are compared and the contents to be corrected are transmitted to the viewer to check whether the program has been updated. The program is updated in the reservation request list (S700).

In this case, even when the broadcast channels are not the same, the same method as in the case where the start time described above is the same is used.

In other words, a program having the same title is searched for, and the broadcast channels of the program are compared, and contents to be modified in the reserved watch list are transmitted to the viewer to check whether the program is updated. The program is updated in the reservation request list (S700).

In addition, even when both the broadcast channel and the start time of the program are not the same, the same method as in the case where the start time described above is the same is used.

In other words, a program having the same title is searched for, and a broadcast channel and a start time are compared with the broadcast channel, and contents to be modified in the reserved watch list are transmitted to the viewer to check whether the program is updated. The program is updated in the reservation request list (S700).

In this case, an embodiment of an interface for notifying a user when updating a reservation request list is illustrated in FIGS. 4A to 4B.

Referring to FIGS. 4A to 4B, when a broadcast channel or a start time of an arbitrary program is changed as shown in FIG. 4A, the user is notified of the change through an information window indicating the change of the change and continuously registered in the reserved watch list. Check.

In addition, as shown in FIG. 4B, even when a program is replaced with another program, the user is notified that the user is replaced, and whether the registered program is registered in the reserved viewing list is checked.

Next, if it is determined that there is no program of the same title (S200), it may be determined that one program is replaced with another program or that the program in the reservation viewing list has not changed.

In this case, when the guide update list is compared with the reserved watch list, a program having the same title cannot be found.

Therefore, when it is determined that there is no program of the same title (S200), the broadcast time is used together with the channel number and the broadcast start time.

First, it is determined whether a program having the same broadcast channel number as the guide update list is in the reserved viewing list (S400).

If there is no program having the same channel number (S400), it is determined that there is no change in the program in the reservation request list, and there is no content to be updated (S800).

When there is a program having the same channel number as the determination result (S400), it is determined whether a program having the same start time as the guide update list is in the reserved viewing list (S500).

As a result of the determination (S500), if there is a program having the same broadcast start time, it is determined that one program has been replaced with another program, and the content to be modified in the reserved watch list is transmitted to the user to check whether the program is updated. The program is updated in the reservation request list (S700).

When there is no program having the same broadcast start time, the determination result (S500) compares the time-duration of each program in the guide update list and the reservation request list to determine whether there is an overlapping time area (S600).

If there is no overlapping airing time (S600), it is determined that there is no content to be updated (S800).

If there is overlapping airtime, that is, if the overlapping portion is longer than a predetermined time, it is determined that the program is replaced, and the content to be modified in the reserved watch list is transmitted to the user to check whether the program is updated. do. The program is updated in the reservation request list (S700).

At this time, in the case of the existing analog broadcast, the start time and channel number and the title of the program is transmitted for the program in KBPS.

The TV receiver compares the version information of the transmitted information to determine whether to update the EPG information, and a guide update list is prepared. This guide update list transmits the start time and channel number of the program and the title of the program for the programs in the reserved viewing list.

The reservation watch list may be updated by comparing the EPG update contents with the programs in the reservation watch list.

In the case of satellite broadcasting, since the detailed information of the program, the broadcast start time, the broadcast time, and the channel information are transmitted to the EPG information, the reservation viewing list can be updated by applying the above method.

As described above, the digital TV reservation viewing method according to the present invention has an effect of providing a convenience for viewing a desired program by updating a broadcast schedule change to a registered reserved viewing program and informing the user of the change.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
