Description

How to set initial OSD language automatically

The present invention relates to a method for automatically setting an initial language for implementing a function of an on screen display (hereinafter, referred to as "OSD") in an imaging apparatus.

More specifically, when the power of the video device is first applied, the OSD language is automatically set to the language of the station that is tuned by the auto tuning function of the video device and the name of the station that is stored in the internal memory of the microcomputer. This eliminates the inconvenience of having to manually set the OSD language for the user who purchased the initial OSD language, and also improves productivity during production because it does not require the installation of an OSD setting diode. There is an advantage to this.

In general, an image recording apparatus such as a magnetic recording and reproducing apparatus or a television receiver is provided with an OSD function, and this function supports a language of a country where the imaging apparatus is used or a language desired by a user.

Accordingly, the video apparatus stores a plurality of languages having contents necessary for realizing the OSD in a storage medium, and the user can change the language from the initial set language as necessary to implement the OSD function.

Conventionally, an option diode using the same principle as a key input is used to set a language for implementing an OSD function.

1 is a principle diagram when an option diode is used for setting the OSD language.

As shown, a, b, and c lines and input signal lines of Key IN 1 and Key IN 2 are connected to each other in a matrix form through option diodes. Here, each option diode represents a language of a specific station, and the microcomputer of the video equipment sends a predetermined pulse signal to a, b, and c one by one, and checks the input signals of Key IN 1 and Key IN 2 to determine a certain function. You can see which option is selected, which language.

For example, when the microcomputer sends a pulse on the a line, if there is an input signal in Key IN 1, the microcomputer knows that the option diode a1 is selected and sets the OSD language to the language of the country corresponding to a1.

Conventionally, the initial language is set at the time of production, and then the user manually sets the OSD language through the language selection menu.

The OSD language setting method using the conventional option diodes as described above sets the initial language after the microcomputer checks and sets the key input signal (Key IN) after the option diode is mounted, which leads to a decrease in productivity at the production stage. There was a problem.

In addition, since the OSD language specified at the time of production is displayed on the initial screen of the video device, a person who intends to use the product in another country may not recognize the language. At this time, the user may have a considerable difficulty in changing to a desired language, and at the same time, the user may have to manually operate the menu for language selection.

Accordingly, an object of the present invention is to purchase a video device having an OSD function, when the power is applied for the first time, automatically tunes the received broadcast, and then implements the OSD function in the language of the first selected country under the control of a microcomputer. The present invention provides an initial OSD language automatic setting method for automatically setting an initial language.

A feature of the initial OSD language automatic setting method according to the present invention for achieving the above-mentioned object is that when the power is first applied to an image device having an OSD function, the station name and the micro station tuned by the automatic tuning function of the video device The present invention provides a method of controlling a language of a matching country among the names of broadcasting stations stored in the internal memory of a computer to automatically set as the initial OSD language.

Hereinafter, a preferred embodiment of the initial OSD language automatic setting method according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram for implementing an auto-tuning function in a magnetic recording / playback apparatus of an image apparatus having an OSD function.

As shown in the figure, in order to implement the auto-tuning function, the microcomputer 210 controls the operation of the entire apparatus, and the pulse width modulation (PWM) signal for tuning the broadcast signal from the microcomputer 210 or the like. A tuner 220 receiving a phase locked loop (PLL) signal and tuning and then amplifying a broadcast signal, and a demodulator 230 which demodulates an intermediate frequency (IF) output signal of the tuner 220 to generate an audio and video signal. And an audio / video signal processing unit 240 for processing and outputting the video and audio output signals of the demodulator 230, and an OSD unit for receiving a video signal output from the audio / video signal processing unit 240 and carrying out texts. A station name detection unit 260 for separating the information indicating the name of the currently received broadcast station mixed with the video output signal from the demodulator 230 and outputting the information to the microcomputer 210; It is composed of volatile memory elements and set by the user such as the pulse width modulation (PWM) or phase locked loop (PLL) signal, which is information for tuning the broadcast signal, and the station name code or OSD language information tuned by the station name detection unit 260. And a storage unit 270 for storing information.

In this configuration, the auto-tuning function is implemented by the following process.

The tuner 220 searches for all the frequency bands in turn and receives the broadcast signal. If the demodulator 230 demodulates the audio and video signals for each broadcast signal, the broadcast station name detection unit 260 demodulates the video output signal. The station name code mixed in the code is separated and stored in the storage unit 270 through the microcomputer 210.

Here, the broadcast station name code is an element constituting the broadcast signal, a value unique to the country in which the broadcast signal is transmitted, and is a unique code of the broadcast station signal.

Under the control of the microcomputer 210, the storage unit 270 controls the microcomputer 210 to tune the broadcast station name code and the broadcast signal to all frequency bands in the same process as described above. The pulse width modulated (PWM) signal or the phase locked loop (PLL) signal applied to the 220 is stored together.

3 is a flowchart for implementing an initial OSD language automatic setting method to which the present invention is applied.

The control method as illustrated is based on the premise that the image device having the OSD function has the auto-tuning function of FIG. 2 and is controlled by the microcomputer as follows.

After purchasing the video device having the OSD function, when the user first applies power (S310), the microcomputer 210 checks whether the broadcasting station information is stored in the storage unit 270 (S320).

The reason for this process is that the producer ships the finished product in a state in which all the data of the memory unit 270 is erased, and, if such a microcomputer 210 is checked, the storage unit 270 is checked. If broadcasting station information is stored, the OSD language is already set, and thus performs other functions desired by the user by inputting an external key.

However, if the broadcasting station information is not stored in the storage unit 270, the automatic tuning function is performed in the same manner as in FIG. 2 to store the broadcast station name code of the tuned broadcast in the storage unit 270 for the first time (S330). ).

In this case, the memory device 270 is usually composed of a nonvolatile memory device in order to prevent loss of stored data, and usually uses non-volatile random access memory (NV-RAM).

The station name codes tuned and stored in this way are compared with the plurality of station name codes stored in the ROM (Read Only Memory) which is the internal memory of the micro computer 210 by the microcomputer 210 at the production stage (S340). It is determined whether or not the same as one of them (S350).

As a result of the determination, if the broadcasting station name code tuned by performing the automatic tuning function and stored in the memory unit 270 and the broadcasting station name code stored in the internal memory of the microcomputer 210 are not the same, The comparison is continued with another one of the station name codes stored in the internal memory (S340). If it is determined to be the same (S350), the language of the country is set as the OSD language to be applied to the device (S360).

In addition, by storing the OSD language information set in such a process in the storage unit 270 (S370), the initial OSD language automatic setting process is completed, and then used as an implementation means of the OSD function according to the use of the device.

As described above, according to the initial OSD language automatic setting method according to the present invention, when power is first applied to an image device having an OSD function, the station name and the inside of the microcomputer are tuned by the automatic tuning function of the image device. By automatically setting the language of the matching country among the names of the stations stored in the memory to the OSD language, it eliminates the inconvenience of the user having to manually set the initial OSD language to be applied, as well as the option diode for OSD language setting. Since the initial language setting is unnecessary, productivity can be improved during production.
