Description of the prior art

In case of detection of abnormalities quality products in a predefined warranty period the supplier will usually repair the defective product or replace it with a new one free of charge.

To service the defective product, to verify if another warranty period of the product, on the written warranty or the outer surface of the product attach a label or tag and the seller writes on it the date of purchase of the product. However, sellers rarely write the purchase date on the written warranty, the label or tag. In addition, even if the seller has recorded the date of purchase, buyers can often lose a written warranty label or tag showing the date of purchase.

Even when the warranty has expired, some buyers intentionally throw a written guarantee and require a free service, which often really is.

Most Korean domestic suppliers of electronic device and product PR is rantio, usually practiced by the warranty within 30 months after production date. However, even if the 30-month term has expired, in order to avoid disputes with customers, insisting on unreasonable demands, they are generally free. Thus, suppliers significantly burdened additional service costs. Also, when determining the warranty period often lead to disputes with customers, which is detrimental to satisfactory customer service.

Brief description of the invention

To solve the aforementioned problems, the present invention is to provide a way to automatically save the information about the date when the product was used for the first time after purchase of the product.

Accordingly, to achieve this goal we propose a method of preserving proprietary information of the electronic device for receiving an input signal containing information about the current date, which includes transaction (a) determining whether the controller of the electronic device a predefined command, (b) if the operation is (a) determined that the predetermined command is entered, the allocation of data on the current date, codedate separately from the service information, stored in memory, and (d) only if the operation (C) it is determined that the original data is present, data about the current date in the field for data about the date.

Brief description of drawings

The above objective and advantages of the present invention will be understood from the detailed description with reference to the accompanying drawings, in which:

Fig.1 depicts a block diagram illustrating the TV, to which is applied the method of automatically store information about the date of the first use of an electronic device according to the present invention; and

Fig. 2 depicts a block diagram illustrating a method of automatically store information about the date of the first use of an electronic device according to the present invention.

Description of the preferred embodiment of the invention

The preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The broadcast station transmits the data relating to real time information and program information of the broadcast together with the video signals and sound signals to facilitate programmable recording, etc. that I different types of the digitally encoded information, which is not contained in the video or audio signals. For example, are used in practice Teletext, SVP (system programs), PSV (programmable video recording system) or ABR (Korean broadcasting system programs).

In comparison with the sound broadcasting system or the broadcasting system, the data transmission system uses a highly efficient means of compressed encoding for transmitting various types of information, providing efficient transfer of information.

In the data transmission system with the use of sound signals, the broadcast AM band transmits data by placing a signal modulated according to the principle of manipulation with minimal displacement (MMS), at lower frequencies, and the broadcast FM band transmits data by placing the modulated signal in the upper side band of frequency subchannels.

These programs ABR emit in a predetermined horizontal line in accordance with the terms of various broadcasting stations within the length of the vertical quenching pulse (Department of fegi) and alternate or odd field or an even field of the selected horizontal line.

In the framework of the present invention will be described data transmission system for transmission of time information and data about the date.

Fig.1 depicts a block diagram illustrating the TV, to which is applied the method of automatically store information about the date of the first use of an electronic device according to the present invention. The TV includes an antenna 101, a tuner 102, the processor 103 of the audio signal, the processor 104 of the video signal splitter 105 data demodulator 106, a controller 107, a memory 108 and keypad 109 input.

The broadcast signals transmitted by broadcasting station are received by the antenna 101, and only the signals of broadcasting channels tuned by the tuner 102, is displayed.

The processor 103 of the audio signal filters only audio signals, demodulates the filtered audio signals and outputs them to the speaker.

The processor 104 video filters only video signals, divides them into color signals and the luminance signal, demodulates and outputs the demodulated signals to a display means such as a cathode ray tube.

In addition, the data of the schedule containing details of the date, p is 05 data and then demodulate the demodulator 106 for subsequent input to the controller 107 in the form of digital data.

Now input method and display the service information concerning the electronic device controlled by the controller 107 in accordance with the present invention, will be described with reference to Fig.2.

At step 201 setting the initial value. That is, data about the date (Ds) relating to the date of the first use of the product, which is one type of service information, set to "0" and then remain at a particular address in the memory 108. This is done to determine that no information about the date was not saved when the purchased product was used for the first time.

At step 202 determines whether the manipulation of the user command to the controller 107 via keypad 109 input. In this case, the command corresponds to the first member of the team when using the product, i.e. the command from the button "enable", which may be another team depending on types of products. In other words, step 202 is designed to determine, entered or not the incoming command from the button to first activate the product after buying it.

At step 203, the data Ds on the date that is stored at a particular address in the memory 108 is read to determine the ACC is anicca at a particular address in memory, the procedure is terminated.

At step 204, if at step 203 it is determined that Ds is "0", only the data Dp on the current date from the data broadcast programs received from the demodulator 106, separated by a controller 107.

At step 205, the data Dp on the current date correspond to a particular address in the memory 108 that stores the data Ds of the date.

The memory 108 is a storage device to store information when power is removed or flash memory, that is, even if the power supply is interrupted, the data stored in it is not lost.

In addition, the service information stored in the memory 108, it is possible to effectively control the installation of such a program controller 107 so that service information can be modified by the introduction of a predefined password.

Through the use of the above-described operations, when the user uses the purchased product for the first time, information about the date of the first use of the product can be stored in memory.

Now will be described how to display information about the date of the first use of the product stored in the memory. Special key for repair and maintenance, also called factory key, ustanavlivaetsya panel 109 entering the product user. In this case, only if you enter the serial key, the controller 107 reads and decodes information about the date, stored at a particular address in the memory 108, and then displays it on the display means via the processor 104 of the video signal. The display means may be in the form of a cathode-ray tube display or a liquid crystal, in accordance with the type of product that has stored data about the date.

In an alternative embodiment, the service information may be displayed as follows. That is key to display the service information, called a key factory type, installed in the keypad 109 user input. Thus, only if you enter this key displays system information stored in the memory. In this case, the controller 107 may be programmed so that the information about the date of the first use of the product stored in the memory 108 may not be changed.

Due to the above operations, information about the date of the first use of the purchased product is automatically saved. Once information about the date of first use is stored in memory, the stored information cannot be changed at the discretion policewatch warranty period.

The present invention has been described on the example of the TV as an electronic device for convenience of explanation. However, to a person skilled in the art it will be obvious that the invention can also be used with a cellular phone without departing from the scope of the invention, that is, the date you install the software for cell phone is saved, and then you can confirm that your cellular phone is provided with a warranty period in case of future repairs.

As described above, according to the present invention, when an electronic device is used for the first time after purchase, the date information is required to confirm the warranty period is automatically saved, through which disputes are resolved regarding warranty terms. In addition, the cost of repair of the products, warranty period which has already expired, can be significantly reduced.
