Description

How to set system time automatically {METHOD FOR SETTING AUTOMATICALLY SYSTEM TIME}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television system, and more particularly, to a method for automatically setting time using KBPS (Korea Broadcasting Program Service) (hereinafter also referred to as "K broadcasting service").

If KBPS module is embedded in a general television, the user can receive KBPS, that is, K broadcasting service. KBPS refers to a service function that displays a program and its specific information of a broadcasting station currently viewed on a screen when a user presses a KBPS key (also referred to as a "K key") by time zone. Broadcasting stations are sending IDs that contain time data, broadcast contents, program classification information, broadcasting station names, and other information to the TV for KBPS. Therefore, if you set the system time of the TV automatically by using K broadcasting service, you do not need to set the time manually.

Accordingly, an object of the present invention is to provide a method of automatically setting a system time using a K broadcast service directly in a television having a KBPS module.

In accordance with the above object, the present invention provides a system time automatic setting method for a television having a Korean broadcast program service module, wherein the time data in the K broadcast service information is read directly from the Korean broadcast program service module in a TV regular broadcast time zone. The system time is set automatically.

1 is a block diagram applied to an embodiment of the present invention,

2 is a control flowchart according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating an embodiment of the present invention, and shows a television receiver incorporating a KBPS module. Referring to FIG. 1, the KBPS module 2 embedded in the television receiver shows a program of a broadcasting station currently viewed on a television screen, that is, a CRT (Cathode Ray Tube) 16 of FIG. 1 when a user presses a K key (KBPS key). Performs a service function that displays information by time zone. When the user immediately presses the K key using the remote controller 6, the microcomputer 4 performs internal communication with the KBPS module 2 based on a preset protocol.

The signal broadcast from the broadcasting station through the antenna 8 is applied to the tuner 10, and the tuner 10 tunes the corresponding broadcasting channel based on the channel selection of the user. The composite video broadcasting signal CVBS tuned by the tuner 10 is applied to the image processor 14 through the KBPS module 2 and the switch 12. Also, the local cable broadcasting may be applied to the image processor 14 through the KBPS module 2 and the switch 12 through the cable 11. The switch 12, which is switched and controlled by the microcomputer 4 (switching control signal SWC), selects the input stage A stage other than the state of providing KBPS (directly K broadcast service). Therefore, the image transmitted from the broadcasting station is displayed on the CRT 16 via the antenna 8, the tuner 10, the switch 12, and the image processor 14. The video sent through the local cable broadcasting station is also displayed on the CRT 16 via the switch 12 and the image processor 14.

2 is a control flowchart according to an embodiment of the present invention, which is a control flowchart of a method for automatically setting a system time in a television with KBPS module 2. The method for automatically setting system time according to FIG. 2 is summarized as automatically setting system time by reading time data in K broadcast service information directly from the KTV service module in a TV regular broadcasting time zone.

Hereinafter, a method for automatically setting system time according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

The television receiver according to an embodiment of the present invention performs FIG. 2 when the current time is not set in the system. Referring to FIG. 2, the microcomputer 4 checks whether the system time is set in the television receiver in step 100 and determines step 102. If the system time is not set, the microcomputer 4 proceeds to step 104. In step 104, the microcomputer 4 internally communicates with the KBPS module 2 to read current time data provided by the K broadcast service and determine the first time data. Thereafter, in step 106, a predetermined time wait (eg, 30 minutes to 60 minutes) is performed, and the process proceeds to step 108. In step 108, the microcomputer 4 internally communicates with the KBPS module 2 to read current time data provided by the K broadcast service and set it as the second time data. Thereafter, in step 110, it is determined whether the time interval between the first time data and the second time data is similar to a predetermined time waiting. If similar, the process proceeds to step 112 of FIG. 2 to recognize the time data in the KBPS module 2 as a valid value, and sets the time data for the present time in the KBPS module 2 to the system time.

The operations of steps 104 to 112 described above are for checking whether the time data in the KBPS module 2 is a valid value. If the time data provided by the KB K service of KBPS Module 2 is TV regular broadcast, the time data is valid. If the time data of the K cable service is recorded for a program previously recorded by a local cable broadcasting station, the time data is valid. It will not (ie wrong time information). Therefore, the system time automatic setting should be made by using the time data provided by the K broadcasting service immediately in the time zone during the TV regular broadcasting.

The method of determining whether the time data of the K broadcast service is the time data provided during the TV regular broadcast or the time data provided by the cable broadcasting station is performed in the control operation of steps 104 to 110 of FIG. It may be determined whether the elapsed time (wait time) is similar to the time interval between time data provided by the K broadcast service. Since different programs previously recorded in a cable broadcasting station are different in time, the time interval between time data provided by the K broadcast service of a local cable broadcasting station is different from the elapsed time (wait time) of the actual time. In step 106 of FIG. 2, the predetermined waiting time is set, for example, from 30 minutes to 60 minutes, because a program broadcasted from a cable broadcasting station changes to another program after approximately 30 minutes to 60 minutes. Therefore, it is desirable that a certain waiting time be determined according to the time of the program broadcast in the cable broadcasting station.

In the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.

As described above, the present invention sets the system time by reading the time data in the K broadcasting service information directly from the Korean broadcasting program service module in the TV regular broadcasting time zone, so that the time is accurate, and when the system time is not set, the user directly sets the system time. There is no need to set this to provide convenience to the user.
