The present invention relates to a satellite broadcast receiving television system that displays the text using OSD characters so that it can be easily understood.

In general, as shown in FIG. 1, a conventional satellite broadcasting television system includes a key input unit 10, a microcomputer 20, a tuner unit 30, a video / audio signal processing unit 40, an OSD unit 50, A monitor 60, a speaker 70, a BS converter 80, a BS tuner unit 90, and a tuner control unit 100 are included.

The key input unit 10 includes a plurality of keys including a reservation selection key for selecting a reservation category, a movement key for moving a category, a confirmation key for finally selecting a category, and the like, to provide a key signal corresponding to a user's key operation. It outputs and transmits / receives a key signal carried on a predetermined infrared carrier using a remote controller that can be input at a remote place and applies it to a microcomputer to be described later.

The microcomputer 20 selectively controls the tuner 30, the BS tuner 90, the video / audio signal processor 40, and the OSD 60 by the key signal from the key input unit. When the reservation selection key signal is applied from the key input unit, a category desired by the user, including all categories, such as news, drama, sports, etc., which are classified into category information included in the broadcast program information by the VPS, is controlled. A category screen from which the user can select is controlled by the OSD unit and displayed.

The tuner unit 30 outputs a broadcast signal received by tuning to a corresponding channel corresponding to the control of the microcomputer to a video / audio signal processing unit to be described later. The video / audio signal processor 40 separates a broadcast signal or a satellite signal applied from the tuner unit or the BS tuner described later into a video and audio signal according to the control of the microcomputer, and the video signal is an OSD unit. Output each to the speaker.

The OSD unit 50 is an apparatus for processing OSD (on screen display) characters on a television screen. The OSD unit 50 reads a text signal corresponding to the control of the microcomputer from the video / audio signal processor so as to be displayed at a predetermined screen position. The synthesized output is performed on an applied video signal or a blue-back signal.

On the other hand, the BS converter 80 outputs a low noise and high amplification of the radio wave received from the parabola antenna at a frequency of 1/10. The BS tuner unit 90 changes the channel of the satellite broadcast and separates the video and audio signals output from the BS converter and outputs them to the video / audio signal processor. The tuner controller 100 outputs a control signal to select terrestrial broadcast or satellite broadcast according to a user's request, and selects and controls the tuner or BS tuner.

However, in general, when receiving satellite broadcasting in Korea, most of the information is related to the viewing area, so it is not necessary to select and highlight the information. However, when watching satellite broadcasting outside the viewing area, most of the information is different. Since it is not common to broadcast information related to a viewing area of a user because it is related to a region, there is a problem that such information is not easy to identify.

Accordingly, an object of the present invention to solve the problems of the prior art as described above is to determine and store the user's area when watching satellite broadcast-received television, and to store the texts of broadcasts broadcasted in countries other than the user's viewing area. The present invention provides a satellite broadcasting receiving television system that displays information using an OSD character so that it can be easily understood when there is information related to a viewing area.

The operation of the satellite broadcast receiving television system according to the present invention configured as described above will be described in detail as follows.

First, satellite broadcasting programs are produced in each country, transmitted through broadcast satellites, supplied to each region, and introduced into each home through a parabolic antenna. Therefore, satellite broadcasts of other countries can be received beyond geographical limits. The satellite broadcast signal introduced into the parabola antenna is input to the BS tuner via a BS converter that low noise and high amplify the radio wave received from the antenna at a frequency of 1/10.

Then, the BS tuner tunes the satellite broadcast signal to the channel corresponding to the user's request, performs FM demodulation, and separates the synthesized video and audio signal in the transmission process. Since the signals are synthesized after being processed by different processes due to the characteristics of each signal, the video and audio signals are recovered through a separate process in the same manner in the restoration of the original signal.

The satellite broadcast signal converted into a signal that can be processed by the video / audio signal processing unit of the television is output to the video / audio signal processing unit and also to the storage unit to detect a character string included in the satellite broadcast signal. Stored. Thereafter, the character recognition unit compares the character string data stored in the storage unit based on the viewing region data stored in the storage unit and determines whether there is information related to the viewing region.

At this time, if the text recognition unit finds that there is information related to the viewing area of the user, the result is transmitted to the microcomputer to perform the appropriate processing for the microcomputer.

The microcomputer received from the character recognition unit that the information related to the viewing area of the user is included in the satellite broadcasting signal of the other country is transferred to the storage unit and drives the OSD unit to display the text as OSD characters and transmits the character string. Allows the string to be displayed with the program currently being aired.

By the above process, by showing OSD information related to user's viewing area included in satellite broadcasting signals of other countries separately, most of them broadcast information irrelevant to the user and obtain useful information that is easy for users to miss. You can enjoy it once more.

As described above, the present invention has been described with reference to preferred embodiments, but the present invention is not limited thereto, and the present invention may be embodied in various forms by adding various limitations or additions without departing from the technical spirit of the present invention.
