The present invention relates to a wide / normal screen automatic recognition device on a set-top-box system, which enables automatic recognition of information.

In general, a screen of a television receiver was output by a program transmitted from a broadcasting station, but a screen of a satellite receiver is output by a program transmitted by a satellite transmitter.

As shown in FIG. 1, the transmitting / receiving device unit of the conventional satellite broadcasting system receives a data signal from the satellite transmitting device unit 1 and the satellite transmitting device unit 1 for transmitting a data signal. An image processor (2) for generating a corresponding video signal, an NTSC converter (3) for receiving an image signal from the image processor (2) and converting it into a corresponding National Television System Committee (NTSC) signal; A signal processor (4) for receiving an NTSC signal from the NTSC converter (3) and simultaneously separating and processing an image, a phase, and a color signal from the NTSC signal, and generating a corresponding composite video signal; and the signal processor And a monitor 5 for receiving the composite video signal from (4) and displaying the composite video signal corresponding thereto.

However, when displaying the image of the satellite broadcast on the monitor using the transmission / reception apparatus section of the conventional satellite broadcasting system as described above, when the data signal output as the wide / normal signal from the satellite transmission apparatus section is displayed on the monitor, Since the screen size of the normal is incorrect, the user directly sees the distortion on the screen and adjusts the setting of the TV, which causes users to experience inconvenience in use.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to enable automatic recognition of a wide / normal screen so that the size of the screen does not need to be set separately by the user. It is to provide a wide / normal screen automatic recognition device on a set-top-box system to provide a service that can be adjusted automatically.

In order to achieve the above object, a wide / normal screen automatic recognition device on a set-top-box system of the present invention receives a data signal carrying a video signal and a wide / normal signal from a satellite transmitter, And a receiver unit for automatically adjusting and displaying a screen size after detecting a wide / normal signal.

Hereinafter, a wide / normal screen automatic recognition device on a set-top-box system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The automatic recognition device includes a receiver 100 having an image processing unit 111, a National Television System Committee (NTSC), a conversion unit 112, and an adder 113; And a receiver 100 comprising a signal processor 121 and a TV (TV receiver) 120 having a monitor 122.

In addition, the signal processor 121 further includes a wide / normal detector 121-1.

The satellite transmitter 1 transmits a data signal carrying a video data signal and a wide (16: 9) / normal (4: 3) signal to the receiver 100. The video data signal is used in line 21 (frequency player 525) or more, and the wide / normal signal is used in line 20 (frequency player 525) or less.

At this time, the line 20 carries "1" representing a wide screen size signal or "0" representing a normal screen size signal.

On the other hand, the receiving apparatus 100 receives a data signal carrying a video signal and a wide / normal signal from the satellite transmitter 1, detects a wide / normal signal among the data signals, and then adjusts the screen size. Automatically adjusts and serves to display through the monitor 122.

At this time, the receiver 110 of the reception device unit 100 receives a data signal from the satellite transmitter 1, performs image signal processing and NTSC conversion on the data signal, and then adds the corresponding addition signal. Output to the TV 120.

In addition, the image processor 111 mounted in the receiver 110 receives a data signal (video data signal and a wide / normal signal) from the satellite transmitter 1 and generates an image signal corresponding thereto. It then serves to output to the NTSC converter 112.

The NTSC converter 112 mounted in the receiver 110 receives an image signal from the image processor 111 and converts the image signal into an NTSC signal and outputs the image signal to the adder 113. do.

At this time, in the data line of the NTSC signal output from the NTSC conversion unit 112, the line 21 (frequency player 525) or more carries a video signal used for video data transmission as in the prior art, and is used for data transmission. The line 20 (frequency 525) or less which is not used will carry a wide signal 16: 9 or a normal signal 4: 3.

In addition, the adder 113 mounted in the receiver 110 receives an NTSC signal from the NTSC converter 112 and at the same time the video signal and the line 20 on the line 21 (frequency player 525) of the NTSC signal. (Frequency Player 525) and adds a wide or normal signal listed below and serves to output the corresponding addition signal to the TV (120).

On the other hand, the TV 120 of the reception device unit 100 receives the addition signal from the adder 113 mounted in the receiver 110 and simultaneously generates a corresponding composite video signal and the monitor 122. It serves to display through.

In addition, the signal processor 121 mounted in the TV 120 receives an add signal from the adder 113 and simultaneously separates and processes an image, a phase, and a color signal from the adder signal, and then composites the corresponding signal. It generates a video signal, and then outputs the composite video signal to the monitor 122.

In this case, the signal processor 121 further includes a wide / normal detector 121-1 that detects whether the adder signal input from the adder 113 is a wide signal or a normal signal.

In addition, the monitor 122 mounted in the TV 120 receives a composite video signal from the signal processor 121 and simultaneously displays a corresponding composite video signal.

Next, an operation process of the wide / normal screen automatic recognition device on the set-top-box system having the above configuration will be described in detail.

First, the image processing unit 111 mounted in the receiver 110 receives a data signal (video data signal and wide / normal signal) from the satellite transmitter 1 and generates a video signal corresponding thereto. After that, the output to the NTSC converter 112.

Then, the NTSC conversion unit 112 mounted in the receiver 110 receives an image signal from the image processing unit 111, converts the image signal into an NTSC signal, and outputs the image signal to the adder 113.

Subsequently, the adder 113 mounted in the receiver 110 receives an NTSC signal from the NTSC conversion unit 112 and at the same time the video signal and the line 20 (shown in line 21 (frequency player 525) of the NTSC signal) After adding the wide or normal signal loaded below the frequency band 525, the corresponding addition signal is output to the TV 120.

Then, the signal processing unit 121 mounted in the TV 120 receives the addition signal from the adder 113 and simultaneously separates and processes the image, phase, and color signals from the addition signal, and then composites the corresponding signal. A video signal is generated, and then the composite video signal is output to the monitor 122.

In this case, the wide / normal detector 121-1 mounted in the signal processor 121 detects whether the adder signal input from the adder 113 is a wide signal or a normal signal.

Subsequently, the monitor 122 mounted in the TV 120 receives the composite video signal from the signal processor 121 and displays the composite video signal corresponding thereto. In detail, the signal processor When the wide signal is detected by the wide / normal detector 121-1 mounted in the 121, the monitor 122 displays an image with a screen size of 16: 9 and is mounted in the signal processor 121. When the wide / normal detector 121-1 detects a normal signal, the monitor 122 displays an image with a screen size of 4: 3.
