Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a channel selection method in digital terrestrial broadcasting, and more particularly to a method of selecting a reception channel by designating a channel number in a digital terrestrial broadcast receiver (hereinafter, simply referred to as a “receiver”). .
[0002]
[Prior art]
Conventionally, in BS digital broadcasting, CS digital broadcasting, and the like, a user has selected a program to be viewed by the following three methods.
[0003]
The first method is to select a channel by operating a numeric key provided on a remote controller or a receiver body and inputting a number assigned to a channel to be viewed. For example, when number keys 1 to 12 are provided, it is possible to select a channel from a maximum of 12 channels.
[0004]
The second method is a method of selecting a program by directly specifying a three-digit channel number.
[0005]
The third method is a channel selection method in which channel numbers are changed in ascending or descending order to search for a channel to view.
[0006]
By the way, in channel selection in terrestrial digital broadcasting, a service ID (hereinafter, referred to as “SID”), which is a number unique to a broadcasting station, is used. This SID matched the three-digit channel number in BS digital broadcasting and CS digital broadcasting. However, in terrestrial digital broadcasting, the number of broadcasting stations is large, and the service differs depending on the region. Since it is composed of an identification number of a service or the like, it is a complicated number to present to a user.
[0007]
For this reason, in terrestrial digital broadcasting, a remote control key ID is defined, and by creating a three-digit channel number based on the remote control key ID, user convenience is ensured. When the user inputs the three-digit channel number, the receiver converts the number into an SID and performs channel selection.

[Problems to be solved by the invention]
Here, when the remote control key IDs of the broadcasting stations are duplicated, the same three-digit channel number exists. In such a case, a one-digit number is added to the receiver after the three-digit channel number, and the channel is selected using the four-digit number. The added fourth digit number is called a branch number.
[0010]
If such a branch number exists when selecting a channel, some programs can be selected by inputting a three-digit channel number, and others cannot be selected unless a four-digit channel number is input. Will be mixed.
[0011]
However, in digital terrestrial broadcasting, since there are many types of broadcasting stations and services, users do not remember whether a three-digit channel number or a four-digit channel number is assigned to each service. However, there is a problem that the operation of selecting a channel becomes complicated.
[0012]
Also, since this branch number is a number that the receiver adds to the three-digit channel number based on the broadcast area and the reception area, when the user moves or resets the receiver, etc. It is possible that the receiver assigns a different branch number to each channel number. In such a case, there has been a problem that the user cannot view the desired program by the previous number designation.
[0013]
In view of such circumstances, the present invention easily selects a channel in a terrestrial digital broadcast without being aware of a mixture of a 3-digit channel number and a 4-digit channel number when a user selects a channel. It seeks to provide a way that can be done.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Each embodiment of the channel selection method of the present invention described below is realized as a function provided in a digital terrestrial broadcast receiver. Here, the terrestrial digital broadcast receiver has the same configuration as the conventional one, and particularly has a database function for storing various data necessary for realizing the tuning method of the present invention. .
[0046]
First, the configuration of this database will be described. FIG. 1 is a diagram showing a configuration example of a database used in the present invention. This database includes a branch number assigned to the same channel number, a channel name corresponding to the branch number, an SID, a tuning number or viewing time, a priority, and the like.
[0047]
When the receiver including the database having such a configuration recognizes that there are a plurality of broadcast stations having the same remote control key ID, the receiver creates the above database for the plurality of broadcast stations. Thereafter, the receiver updates this database every time a channel number having a branch number is selected. In the example of the database shown in the figure, the number of times of channel selection is counted each time a channel is selected.
[0048]
When the viewing time is used in the database, the time measurement is started when a channel existing in the database is selected, and the measurement ends when another channel is selected. In this way, the viewing time is calculated, and the viewing time stored in the database is updated.
[0049]
Furthermore, when updating the database, the number of tunings and the viewing time are compared between the branch numbers, and the priority of each branch number is determined based on predetermined conditions such as a large number of tunings and the length of the viewing time. Decisions are made and written to the database.
[0050]
In this database, the receiver is not only automatically updated, but also the user can browse the database and freely change the priority and the like. In this way, when the priority of the newly added branch number is to be the highest, the user can change the priority without performing an operation of repeatedly selecting a channel. It is preferable that the priority rewritten by the user is always higher than that automatically determined by the receiver, so that the priority is not rewritten by the receiver.
[0051]
Next, an embodiment of the tuning method of the present invention realized in a receiver including the above-described database will be described below.
[0052]
FIG. 2 is a flowchart showing the operation flow of the user and the receiver in the first embodiment of the tuning method of the present invention.
[0053]
In process 201, the user starts channel selection using a three-digit channel number. In process 202, the receiver displays a channel number display area on the screen display unit and prompts the user to input a channel number. In step 203, the receiver displays the channel number input by the user in the channel number display area.
[0054]
In step 204, the receiver refers to the database to check whether the channel number input by the user has a branch number. If there is a branch number, in step 205, the receiver checks the branch number of the channel number. Select the last number you watched. If there is no branch number in the process 204, the process directly proceeds to the process 206. In step 206, the receiver converts the three- or four-digit channel number into an SID, and in step 207, starts channel selection using the SID.
[0055]
According to the channel selection method of the present embodiment, after the user inputs a channel number, the receiver determines whether or not a branch number exists in the channel number, and if so, automatically adds the branch number. Since the channel selection is started, the user can select a desired channel without performing an operation of adding a branch number to the channel number.
[0056]
FIG. 3 is a flowchart showing the operation flow of the user and the receiver in the second embodiment of the tuning method of the present invention.
[0057]
In process 301, the user starts channel selection using a three-digit channel number. In process 302, the receiver displays a channel number display area on the screen display unit, and prompts the user to input a channel number. In step 303, the receiver displays the channel number input by the user in the channel number display area.
[0058]
In step 304, the receiver refers to the database to check whether the channel number input by the user has a branch number. If there is a branch number, in step 305, the receiver enlarges the channel number display area. To display a fourth digit input space on the screen to prompt the user to input a branch number. In step 306, the receiver confirms that the fourth digit has been input by the user, and proceeds to step 309.
[0059]
The receiver measures the lapse of time after displaying the fourth digit input space, and determines in process 307 whether a predetermined time has elapsed. If the fixed time has not elapsed, the process returns to step 306 to wait for the user to input a branch number. In the process 307, when the predetermined time has elapsed, the process proceeds to the process 308, and the receiver refers to the database and selects the branch number having the highest priority from the plurality of branch numbers.
[0060]
In the process 304, if there is no branch number in the channel, the process proceeds to the process 309.
[0061]
In process 309, the receiver converts the three- or four-digit channel number into an SID, and in process 310, starts channel selection using the SID.
[0062]
FIG. 4 is a display example of a receiver screen when the tuning method of the present embodiment is performed. When the user starts tuning, a three digit input space is displayed as a number display area on the screen, and the user can input a channel number (screen 401). After the three-digit channel number is input (screen 402), if it is determined that there is a branch number, the number display area is enlarged, the fourth digit input space is displayed, and the user enters the four-digit channel number. It becomes possible to input the branch number of the eye (screen 403). In this screen, when the user inputs a branch number (screen 404), channel selection is performed based on the 4-digit channel number (screen 405).
[0063]
If the user does not input a branch number within a certain period of time after the input space of the fourth digit of the branch number is displayed, the receiver refers to a database held therein and sets a priority. After acquiring the branch number with the highest degree, tuning is performed (screen 405).
[0064]
After the user inputs a three-digit channel number, if it is determined that there is no branch number in the channel number, channel selection is performed based on the three-digit channel number (screen 405).
[0065]
According to the channel selection method of the present embodiment, when a branch number exists in the three-digit channel number input by the user, the user can be prompted to input the branch number. If the user does not input a branch number even after a certain period of time, the receiver automatically adds the branch number and starts channel selection. Thus, if the user knows the branch number to be added to the channel number, the user can specify the branch number and select a channel. If the user does not know the branch number, the branch number is automatically added at the receiver. It is possible to do so.
[0066]
FIG. 5 is a flowchart showing the operation flow of the user and the receiver in the third embodiment of the tuning method of the present invention. In the figure, operations in processing 501, processing 502, and processing 503 are the same as the corresponding processing in the first embodiment and the processing in the second embodiment, and a description thereof will not be repeated.
[0067]
In operation 504, the receiver refers to the database to check whether the 3-digit channel number input by the user has a branch number. If there is a branch number, in step 505, the branch number of the channel number and its priority are acquired with reference to the database. Subsequently, in process 506, the receiver creates a list of branch number channels based on the priority obtained in process 505, and displays this on the screen. On this screen, the user can select one of the channels of each branch number.
[0068]
In the process 507, when the user selects the branch number channel desired to be viewed from the list displayed on the screen, the process proceeds to the process 509.
[0069]
The receiver measures the lapse of time since displaying the list of the channel of the branch number, and determines whether or not a predetermined time has elapsed in process 508. If the fixed time has not elapsed, the process returns to step 507 to wait for the user to select a branch channel. In the process 508, when the predetermined time has elapsed, it is determined that the currently selected channel in the list has been selected, and the process proceeds to the process 509.
[0070]
If the branch number does not exist in the channel in the process 504, the process proceeds to the process 509.
[0071]
In step 509, the receiver converts the three- or four-digit channel number into an SID, and in step 510, starts channel selection using the SID.
[0072]
FIG. 6 is a display example of a receiver screen when the tuning method of the present embodiment is performed. When the user starts tuning, a three-digit input space is displayed as a number display area on the screen, and the user can input a channel number (screen 601). After the input of the three-digit channel number (screen 602), if it is determined that there is a branch number, the receiver refers to the database and displays a list of branch numbers together with the channel name (screen 603). Thereafter, when the user operates a cursor key or the like of the remote controller to select a channel in the displayed branch number list (screen 604), the channel is selected (screen 605).
[0073]
On the screen 603, if a key operation by the user is not performed within a certain period of time, it is determined that the currently selected channel in the list has been selected, and the channel is not selected. Is displayed (screen 605).
[0074]
After the user inputs a three-digit channel number, if it is determined that there is no branch number in the channel number, channel selection is performed based on the three-digit channel number (screen 605).
[0075]
According to the channel selection method of the present embodiment, based on the information included in the database of the receiver, information on each branch number of the channel number input by the user is displayed according to the priority, so that the user can perform a simple operation. It is possible to select a channel desired to be viewed from among a plurality of branch numbers.
[0076]
FIG. 7 is a flowchart showing the flow of the operation of the user and the receiver in the fourth embodiment of the tuning method of the present invention. In the figure, operations in processes 701, 702, and 703 are the same as those in the first embodiment and the corresponding processes in the second embodiment, and a description thereof will not be repeated.
[0077]
In step 704, the receiver refers to the database to check whether the channel number input by the user has a branch number. If there is a branch number, in step 705, the receiver enlarges the channel number display area. To display a fourth digit input space on the screen to prompt the user to input a branch number. In step 706, the receiver confirms that the fourth digit has been input by the user, and proceeds to step 712.
[0078]
The receiver measures a lapse of time after displaying the fourth digit input space, and determines whether or not a certain time has elapsed in a process 707. If the fixed time has not elapsed, the process returns to step 706 to wait for the user to input a branch number. In the process 707, when the predetermined time has elapsed, the process proceeds to the process 708.
[0079]
In step 708, the receiver refers to the database and acquires the branch number of the channel number input by the user and its priority. Subsequently, in process 709, the receiver creates a list of branch number channels based on the priority acquired in process 708, and displays this on the screen. On this screen, the user can select one of the channels of each branch number. In the process 710, when the user selects the channel of the desired branch number from the list displayed on the screen, the process proceeds to the process 712.
[0080]
The receiver measures the lapse of time after displaying the list of the channel of the branch number, and determines whether or not a certain time has elapsed in a process 711. If the fixed time has not elapsed, the process returns to step 710 and waits for the user to select a branch channel. In the process 711, when a predetermined time has elapsed, it is determined that the currently selected channel in the list has been selected, and the process proceeds to the process 712.
[0081]
In step 704, if there is no branch number in the channel, the process proceeds to step 712.
[0082]
In step 712, the receiver converts the three- or four-digit channel number into an SID, and in step 713, starts channel selection using the SID.
[0083]
According to the channel selection method of the present embodiment, the advantage that the user can input the branch number in the second embodiment of the present invention and the information on each branch number in the third embodiment of the present invention are displayed. However, both of the advantages that the user can select a channel to view based on this can be obtained.
[0084]
Further, according to the channel selection method of each embodiment of the present invention, the branch number changes when the user moves or resets the receiver by using the database provided in the receiver. Can be prevented.
[0085]
By the way, this database is used at the time of channel selection, but can also be used when a channel search operation or the like is executed again after the database is created. When a channel search operation is performed and a broadcast station with the same remote control key ID is found, the receiver orders the broadcast stations in order of branch numbers according to the priority of prefectural area broadcast for the residential area → wide area broadcast → cross-border reception. I will put on.
[0086]
Since this branch number is determined by the receiver, first, as shown in FIG. 8, from the state (1) in which only a broadcast station outside the area for cross-border reception exists, the broadcast station having the same remote control key ID is changed to the area When the broadcast is started within (2), a newly added broadcasting station is given a large numbered branch number (branch number 2 in FIG. 8).
[0087]
When the channel search is performed again in such a state, the branch number may be changed from the above-described priority. For example, in the state of (2) shown in FIG. 8, since the newly established broadcasting station B is within the reception area of the user, it is given a smaller branch number than the broadcasting station A outside the reception area of the user. , The broadcast station B is changed to the branch number 1 and the broadcast station A is changed to the branch number 2 (3).
[0088]
However, at this time, since the relationship between the SID and the branch number is stored in the database of the receiver, the receiver can maintain the priority of the previous branch number by referring to the database (4). .
[0089]
Note that the channel selection method in the digital terrestrial broadcasting of the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the present invention.
[0090]
【The invention's effect】
As described above, according to the channel selection method of the present invention, in digital terrestrial broadcasting, when a user selects a channel, the user can easily perform the operation without being aware of the mixture of a three-digit channel number and a four-digit channel number. Tuning can be performed.
[0091]
Further, according to the present invention, according to the channel selection method, it is possible to prevent the branch number added to the channel number from being changed even when the user moves or the receiver is reset.
