BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of tuning and updating broadcast information in a digital broadcast receiver. For example, in various types of digital broadcast receivers, such as a set top box (STB) or a digital television (D-TV), automatic tuning is performed. The present invention relates to a tuning and broadcasting information updating method in a digital broadcasting receiver for efficiently updating and storing new tuning frequency and broadcasting information.

In general, a digital broadcast receiver such as a set-top box (STB) or a digital television (D-TV) capable of receiving digital satellite broadcasting, digital cable broadcasting, or digital terrestrial broadcasting is widely used. In recent years, By using the digital broadcast receiver, the number of broadcast channels that a user can tune in is rapidly increasing.

Meanwhile, in the digital broadcasting, broadcast service information (SI) is provided to provide convenience to a user, and the service information (SI) includes a broadcast channel number, a broadcast station name, broadcast program information, and the like. The same various broadcast information is transmitted.

In addition, the digital broadcast receiver, for example, the set top box STB, includes, for example, a tuner 10, a demux 11, an audio buffer 12, and a video buffer 13 as shown in FIG. 1. The data buffer 14, the MPEG decoder 15, the detector 16, the microcomputer 17, the OSD generator 18, the memory 19, and the timer 20 may be configured to be included.

In addition, in the microcomputer 17 of the digital broadcasting receiver, when performing an auto tuning operation according to a user's request, for example, the tuner 10 is operated to control the entire broadcast frequency. Band) is sequentially scanned, and the detector 16 detects the level and the intensity of the broadcast signal received through the tuner 10 and becomes equal to or greater than a preset reference signal level and the intensity. Then, the corresponding detection signal is output to the microcomputer.

On the other hand, when the microcomputer 17 receives the detection signal, the microcomputer 17 temporarily stores the current tuning frequency as a valid tuning frequency, and receives service information received through the demux 11 and the data buffer 14 ( In SI), after searching and extracting broadcast information such as a corresponding broadcast channel number, a broadcast station name, and the like, a series of operations are performed in association with the temporarily stored tuning frequency.

In addition, when the microcomputer 17 sequentially scans all the bands of broadcast frequencies, the effective tuning frequency and broadcast information are stored and stored in the memory 19 as tuning and broadcast information. For example, as shown in FIG. 2, the tuning frequency, the broadcasting frequency, the broadcasting channel number, the broadcasting station name, and the like are associated with the tuning and broadcasting information. Can be recorded.

In addition, the microcomputer 17 searches for the tuning and broadcasting information to search for a broadcasting channel desired by the user, and sets reservation information (Reservation_Info) information desired by the user. The information may include a broadcasting channel number, a broadcasting station name, and a reservation time (or broadcasting program name) information. The preference channel information corresponding to the broadcasting channel frequently tuned by the user may include: Channel numbers, broadcast station names, and the like may be recorded.

However, in the conventional digital broadcasting receiver, when the automatic tuning operation is performed as described above, the previously stored tuning and broadcasting information is unconditionally updated with new tuning and broadcasting information. Specific broadcast information, for example, adult broadcast channels previously deleted by the user, are included in the new tuning and broadcast information, causing a problem that children or teenagers watch adult broadcast channels.

In addition, since the reservation information and the preferred channel information are information set based on previously stored and managed tuning and broadcast information, a problem of inconsistency with the newly updated tuning and broadcast information may occur, as well as a new update by the user. Since the tuned and broadcast information that has been previously compared with the previously stored and managed tune and broadcast information cannot be compared, a problem arises in that a desired broadcast channel is incorrectly selected.

Accordingly, the present invention has been created to solve the above problems, for example, in the various types of digital broadcasting receivers such as set-top boxes (STB) or digital television (D-TV), Auto Tuning operation (Auto Tuning) operation When performing the operation, the new tuning and broadcasting information is compared with the previously stored and managed tuning and broadcasting information, and the comparison result is displayed, and according to the broadcasting information arbitrarily set, edited and deleted by the user, the tuning and The present invention provides a method for updating tuning and broadcasting information in a digital broadcasting receiver for selectively updating and updating broadcast information, and for storing reservation information and preferred channel information in accordance with new tuning and broadcasting information. will be.

According to an aspect of the present invention, there is provided a method of updating a broadcast and broadcast information in a digital broadcast receiver, the method including: temporarily storing, in association with a valid tuning frequency and broadcast information, an automatic tuning operation; Comparing the temporarily stored tuning frequency and broadcast information with preset tuning and broadcast information; Displaying the comparison result on an OS screen and searching for a user flag set in the tuning and broadcasting information; And selecting four tuning frequencies and broadcast information for which the user flag is not set, and updating and storing them with new tuning frequencies and broadcast information.

In addition, after comparing the temporarily stored tuning frequency and broadcast information with preset reservation information or preferred channel information, the reserved information or preferred channel information for which a user flag is not set is selected and updated and stored with new tuning frequency and broadcast information. Characterized in that it further comprises the step of.

Hereinafter, a preferred embodiment of a tuning and broadcast information updating method in a digital broadcast receiver according to the present invention will be described in detail with reference to the accompanying drawings.

First, the present invention can be applied to various types of digital broadcast receivers, such as a set top box (STB) or a digital television (D-TV). For example, for a digital broadcast receiver to which the present invention is applied, see FIG. 1. As described above, the tuner 10, demux 11, audio buffer 12, video buffer 13, data buffer 14, MPEG decoder 15, detector 16, microcomputer 17 , The OSD generator 18, the memory 19, and the timer 20 may be included.

Meanwhile, the memory 19 stores and manages tuning and broadcasting information. For example, as shown in FIG. 4, the tuning and broadcasting information includes a tuning frequency and a channel number. ), And a broadcasting station name and the like are recorded and recorded, and a user flag indicating whether the information is set, edited, or deleted by the user is additionally recorded.

For example, as shown in FIG. 4, when a broadcaster name recorded in association with a first tuning frequency # 1 is edited and recorded from 'SBS' to 'Seoul broadcast' by a user's editing operation, '1' is set in the user flag of the broadcasting station name.

In addition, when a broadcasting station name recorded in association with a third tuning frequency # 3 is edited and recorded from 'KBS' to 'Korean broadcasting' by a user's editing operation, '1' is set in the user flag of the broadcasting station name. In addition, when the broadcasting channel number recorded in association with the third tuning frequency is set and recorded from 'CH 9' to 'CH 1' according to a user's setting operation, the broadcasting channel number is set to '1' in the user flag of the broadcasting channel number. Will be set.

If the m th tuning frequency corresponding to the m th tuning frequency (m), for example, an adult broadcasting channel, is deleted by the user's delete operation, set '1' to the user flag of the tuning frequency. Done.

In addition, as shown in FIG. 5, when a broadcaster name included in reservation information or preferred channel information is edited by a user, '1' is set to a user flag of the broadcaster name. Then, the microcomputer 17 In the case of performing an automatic tuning operation to update and record new tuning and broadcast information, the user flag is not set to '1' after retrieving the user flag from previously stored and managed tuning and broadcast information. With respect to the information only, a series of operations for selectively updating with new tuning and broadcasting information are performed. This will be described in detail below.

6 and 7 illustrate an operation flowchart of a method of updating a broadcasting and broadcasting information in a digital broadcasting receiver according to the present invention. For example, in the microcomputer 17, a user requests an automatic tuning operation. Or, when a predetermined time is set in advance, the operation mode of the digital broadcast receiver is set to the automatic tuning mode.

The microcomputer 17 operates and controls the tuner 10 to sequentially scan all bands of broadcast frequencies, and the detector 16 controls the tuner 10. When the level and the intensity of the broadcast signal received through the detection is greater than or equal to the preset reference signal level and intensity, the corresponding detection signal is output to the microcomputer.

On the other hand, when receiving the detection signal, the microcomputer 17 determines that the broadcast signal is normally detected (S12), and temporarily stores the current tuning frequency as a valid tuning frequency, and further, the demux 11 and In the service information (SI) received through the data buffer 14, after searching and extracting broadcast information such as a broadcast channel number and a broadcast station name (S13), a series of operations are performed in association with the temporarily stored tuning frequency. (S14).

When the microcomputer 17 sequentially scans all the bands of the broadcast frequency (S15), the effective tuning frequency and the broadcast information are tuned to the memory 19 in advance. After comparing with the broadcast information (S16), the operation of the OSD generating unit 18 is controlled to generate and output the OSD image showing the comparison result list (S17). For example, in the comparison result list, only new tuning and broadcasting information that does not match the previous tuning and broadcasting information may be selectively displayed.

On the other hand, in the microcomputer 17, when the user requests an update operation or a predetermined time elapses while the OS video is outputted and displayed as described above, the previous tuning and broadcasting information is updated. In this case, the microcomputer 17 searches for and confirms the user flag described above with reference to FIG. 4 (S19).

In addition, the information in which the user flag is set to '1' is determined as information arbitrarily set, edited or deleted by the user, and the remaining information except for the information, that is, the tuning and broadcasting in which the user flag is not set to '1' The information is selectively updated with new tuning and broadcasting information (S20). For example, as shown in FIG. 4, a broadcasting station name (e.g., '') associated with the first tuning frequency # 1 is recorded. Seoul Broadcasting ') will remain the same.

In addition, the broadcasting station name (eg, 'Korean broadcasting') and the broadcasting channel number (eg, 'CH 1') recorded in association with the third tuning frequency # 3 are maintained, and the m th tuning frequency is maintained. #m), for example, '1' is set and maintained in the user flag of the tuning frequency so that the mth tuning frequency corresponding to the adult broadcast channel is not tuned by channel selection.

On the other hand, the microcomputer 17 updates the reserved information and the preferred channel information stored and managed in the memory 19 with reference to the new tuning and broadcasting information updated and stored as described above. After searching and confirming the user flag described above, the user flag is determined to be information set, edited, or deleted by the user arbitrarily, and the remaining information other than the information, that is, the user flag is' Only information that is not set to 1 'is selected and updated to match new tuning and broadcasting information (S21).

For example, as shown in FIG. 5, the broadcasting station names included in the reservation information and the preferred channel information are kept as they are, and the remaining channel numbers are updated to match the new tuning and broadcasting information. In 17), any corresponding operation requested by the user is performed (S22).

Or more, preferred embodiments of the present invention described above, for the purpose of illustration, those skilled in the art, within the technical spirit and the technical scope of the present invention disclosed in the appended claims below, to further improve various other embodiments Changes, substitutions or additions will be possible.

In the tuning and broadcasting information updating method of the digital broadcasting receiver according to the present invention as described above, the user can easily compare and check the new tuning and broadcasting information and the preset tuning and broadcasting information through the OS screen, In addition, it is possible to prevent the name of a broadcasting station arbitrarily edited by a user, a channel number arbitrarily set, or a tuning frequency arbitrarily deleted from being unconditionally updated by an automatic tuning operation. It is a very useful invention that can be updated and stored in accordance with new tuning and broadcasting information.
