BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a specific channel tuning apparatus for television, and more particularly, to a specific channel tuning apparatus for television so that only a specific person can tune into a specific channel of the television.

At present, in order to meet the needs of the viewers, various broadcasting programs such as sports, dramas, current news, and hobby entertainment are broadcast for each broadcasting channel in order to satisfy the needs of viewers. Thus, various programs are broadcast through one broadcasting channel. Since similar programs are broadcasted for each broadcast channel by time zone, there is a problem that viewers cannot appropriately select a broadcast suited to their taste. Therefore, an educational broadcasting channel mainly for students is established and broadcasts an educational broadcasting program, a language broadcasting program, or a hobby program for hobby activities to supplement the subjects taught at school in each time zone. However, it is desirable to establish a professional broadcasting channel that broadcasts only broadcast programs having its own characteristics, such as sports broadcasting channels specializing in sports relaying like foreign countries, and adult broadcasting channels for adults. However, when a professional broadcasting channel (for example, an adult broadcasting channel) is newly established as described above, a scheme for allowing only a specific person to watch the broadcasting channel (for example, preventing minors from watching an adult broadcasting channel) should be developed.

Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to provide a specific channel selecting apparatus of a television for allowing only a specific person to watch a specific channel through a fingerprint input of a viewer.

According to a preferred embodiment of a specific channel tuning apparatus of a television according to the present invention for achieving the above object; A key input unit for controlling input of a television, an OSD storage unit for storing OSD characters, an OSD control unit for processing the OSD characters stored in the OSD storage unit and outputting them to an RGB output unit, according to a key input signal from the key input unit A microcomputer having a microcomputer for outputting a control signal to the OSD control unit and outputting the OSD control unit and the corresponding OSD character to the RGB output unit so that the OSD character is mixed with a television video signal and outputted as a CRT; A fingerprint input unit for capturing a fingerprint input and generating image data according thereto, a fingerprint image processing unit for signal processing image data from the fingerprint input unit and generating code data according thereto, and a fingerprint inputted by the key input unit under the control of the microcomputer. When the storage mode is set, a fingerprint image storage unit for storing code data from the fingerprint image processing unit 28 and the fingerprint for the fingerprint input through the fingerprint input unit while a specific channel is tuned under the control of the microcomputer. A fingerprint control unit which checks whether code data from an image processing unit is code data stored in the fingerprint image storage unit in a pattern matching method; When a specific channel is tuned by a key input from the key input unit, the microcomputer transmits code data corresponding to a fingerprint input through the key input unit to the fingerprint image storage unit based on a fingerprint matching result from the fingerprint control unit. The tuner is controlled such that a specific channel is tuned only when it matches any stored code data.

According to the present invention configured as described above, only a specific person can watch a specific channel through the fingerprint input of the viewer, so for example, if a professional broadcasting channel such as an adult broadcasting channel targeting only a specific person is newly established, Only the equipped measurer can watch the broadcast channel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a specific channel tuning apparatus for television according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a specific channel tuning apparatus according to the present invention, in which reference numeral 12 is a tuner for converting a frequency of a channel signal tuned according to the tuning signal into an intermediate frequency signal which is easy to amplify, and 14 is the tuner. An intermediate frequency (IF) amplifying unit for amplifying the intermediate frequency signal from (12), 16 is an image signal processing unit for performing image signal processing on the amplified signal from the intermediate frequency amplifying unit 14, and 18 is the video signal processing unit. An RGB output unit which converts the video signal from (16) into an RGB signal and outputs it to the CRT 34.

Reference numeral 20 is, for example, installed on the control panel installed at the front lower part of the remote controller or the main body, and includes a volume key for adjusting the volume, a channel key for changing the channel, and a power key for turning on / off the power. The key input section.

In addition, reference numeral 24 denotes an OSD storage unit in which an OSD guide message character is stored, and 22 indicates a corresponding OSD guide message character stored in the OSD storage unit 24 according to a control signal of the microcomputer 10. An OSD control unit outputs to the RGB output unit 18. In the RGB output unit 18, when the OSD guide message text signal input from the OSD control unit 22 is input, the OSD guide message text signal is output to the image signal processor. It is mixed with the television video signal input from (16) and output to the CRT 34.

Also, reference numeral 26 denotes a fingerprint input unit for receiving a user's fingerprint by being placed in a predetermined portion of the coronary tube of the television. In the present invention, the fingerprint input unit 26 is equipped with an image pickup device and then scans the input fingerprint. Convert to and output the function.

Reference numeral 28 denotes a fingerprint image processing unit which processes the fingerprint image data input from the fingerprint input unit 26 and outputs code data corresponding thereto, and 30 denotes a fingerprint input from the fingerprint input unit 26 in the fingerprint storage mode. A fingerprint image storage unit for storing code data according to image data, for example, comprising an EEPROM for image storage, and 32, code data from the image processing unit 28 is stored in the fingerprint image storage unit in a PATTERN MATCHING method. It is a fingerprint control unit that checks whether the code data stored in (30) matches any of the code data stored in the fingerprint image storage unit (30).

The reference numeral 10 outputs a control signal to the OSD controller 22 according to the key input signal from the key input unit 20 so that the OSD controller 22 accesses the OSD storage unit 24 to guide the OSD. By outputting the message text to the RGB output unit 18, the OSD guide message text is mixed with the television video signal and output to the CRT 34, and specified by key input from the key input unit 20. When the channel selection signal for the channel is input, the fingerprint control unit 32 is controlled to compare the fingerprint input signal currently input through the fingerprint input unit 26 with the fingerprint image previously stored in the fingerprint image storage unit 30. Only when they match, the tuner 12 outputs the tuning data for the particular channel to the tuner 12 so that the measurement channel is tuned.

Next, a detailed description will be given with reference to a flowchart shown in FIG. 2 of the operation of a specific channel tuning apparatus of a television according to an embodiment of the present invention configured as described above.

First, in step S1, the microcomputer 10 determines whether the fingerprint input mode is set in the key input unit 20. If the fingerprint input mode is set (YES in step S1), the microcomputer 10 controls the OSD control unit 22 in step S2. The fingerprint input guide message stored in the OSD storage unit 24 is output to the CRT 34 via the RGB output unit 18. At this time, when the viewer touches the fingerprint input unit 26, the fingerprint input unit 26 captures the user's fingerprint, generates image data corresponding to the fingerprint, and then applies the fingerprint image processing unit 28 to the fingerprint image processing unit 28. The processing unit 28 generates the code data by signal processing the image data. Subsequently, when the code data generated in the fingerprint image processing unit 28 is stored in the fingerprint image storage unit 30 (step S3), the control returns to the above-described step S1.

As a result of the determination in step S1, if the fingerprint input mode is not set in the key input unit 20 (NO in step S1), the control proceeds to step S4 to specify a specific channel (e.g., channel 3) in the key input unit 20. If there is a preset input of a specific channel (e.g., channel 3) (YES in step S4), the OSD control unit is temporarily held and the previous channel preset state is maintained. The control unit 22 controls the fingerprint input guide message stored in the OSD storage unit 24 to the CRT 34 via the RGB output unit 18. At this time, when the viewer touches the fingerprint input unit 26, the fingerprint input unit 26 captures a fingerprint through the image pickup device and outputs image data corresponding to the fingerprint to the fingerprint image processing unit 28. ) Determines whether code data corresponding to the image data is stored in the fingerprint image storage unit 30 using a pattern matching method, and applies the matching result to the microcomputer 10. Accordingly, when the matching result of the matching fingerprint is input from the fingerprint control unit 32, the microcomputer 10 proceeds to step S9 (YES in step S6), and the matching result of no matching fingerprint is input. If so (NO in step S6), the control proceeds to step S7 (step S6).

In step S7, the previous channel selection state is maintained, and the OSD control unit 22 controls the OSD storage unit 24 to access an OSD message indicating that there is no fingerprint matching the currently input fingerprint. 18), the control proceeds to step S1 described above after outputting to the CRT 34 (steps S7, S8).

In the step S9, the microcomputer 10 outputs the tuning data to the tuner 12 based on the specific channel tuning signal that has been previously set so that the specific channel is tuned, and then the control proceeds to the step S1. Done.

On the other hand, when the tuning input of a specific channel (for example, channel 3) is not made in the key input unit 20 and the tuning input of another channel is made (NO in step S4), the control returns to step S10. Proceeding to output the tuning data to the tuner 12 based on the channel tuning signal so that the corresponding channel is tuned, then control proceeds to step S1.

As described above, according to the present invention, since only a specific person can watch a specific channel through the fingerprint input of the viewer, for example, when a professional broadcasting channel such as an adult broadcasting channel for a specific person is newly established, Only the same specific person can watch the broadcast channel.
