As an example, the NEC code is constructed as shown in Table 2, and more particularly, a detailed remote controller code of the LG TV is constructed as a HEXA code as shown in Table 3.
Accordingly, the codes divided by manufacture companies and functions are converted into infrared rays through a transmitting means in a remote controller, that is, a light emitting diode (LED) when an operator presses a corresponding button of a remote controller, and then input to an infrared ray receiving terminal of a corresponding an electronic apparatus.
Subsequently, the infrared signal received in the infrared ray receiving terminal is decoded, and a microprocessor recognizes corresponding operation commands and controls a relevant structure, thereby performing an operation commanded by an operator.
However, since code systems are different from one another according to manufacture companies and models, separate remote controllers are provided to the corresponding products. In case of a general family, not a certain product but various electronic apparatuses from different manufacture companies are used. Also, at least three remote controllers are used because models and functions may be different from one another even in case of the same manufacture company.
To use multiple remote controllers correspondingly to products troubles a user, and it is also difficult to maintain the multiple remote controllers. Recently, even though union remote controllers for controlling some electronic products by unifying them are on the market, the union remote controllers have limited controlling scopes, thereby causing a problem in that they do not actively cope with codes which will be changed later.

DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
As shown in FIG. 1, a union remote controller information providing system according to the present invention includes each manufacture company 11 for requiring remote controller information of the manufacture company 11; a data base (D/B) for storing remote controller information provided from the corresponding manufacture company 11, such as code information for each manufacture company and model and text or graphic information for displaying each function, according to manufacture companies and models; and a server 12 for operating an Internet site which provides remote controller information required through a union remote controller 14 by a user.
At this time, the union remote controller 14 is realized by using a mobile communication terminal or a general remote controller which is one of the most widely used electronic apparatuses.
The mobile communication terminal has an Internet access function and a memory which downloads predetermined information through the Internet access function and stores the downloaded information. Accordingly, the mobile communication terminal can be used as a union remote controller just by adding a means which can transmit an infrared signal according to the various codes.
FIG. 2 illustrates a construction of a union remote controller using a mobile communication terminal according to the present invention. A general mobile communication terminal includes a display unit 21 including a liquid crystal panel and a signal process structure for displaying an image in the liquid crystal panel; a communication module 22 for telephone communication and Internet communication; a user interface unit 23 including a key panel for a user's inputting telephone numbers and various operation commands; a memory 25; and a controlling unit 24 for controlling an operation of the aforementioned construction.
A union remote controller according to the preset invention is constructed by adding a program for selecting and controlling a remote controller function and a telephone function to the controlling unit 24 and by adding an infrared ray transmitting unit 26 for transmitting an infrared ray signal corresponding to a user's operation commands to the remote controller function.
FIG. 3 illustrates a construction of a union remote controller using a general remote controller according to the present invention. In FIG. 3, remote controller information is downloaded by accessing an Internet TV or a PC.
General remote controller includes a user interface unit 31 including a key panel for inputting various function commands; a memory 36; an infrared transmitting unit 34 for transmitting an infrared signal; and a controlling unit 33 for controlling the infrared ray transmitting unit 34 so as to transmit an infrared ray signal corresponding to a user's operation command which is input through the user interface unit 31. A union remote controller according to the present invention is constructed by adding a communication module 32 for receiving remote controller information; a display unit 35 including an image process circuit 37 and a display window 38 such as an LCD for displaying image information about lists of an electronic apparatus and functions of a remote controller which a user wants to control; and a program for selecting and controlling the electronic apparatus.
At this time, the communication module 32 can not perform Internet access and data downloading by a remote controller itself. Accordingly, the communication module 32 is constructed to fit the communication standard of a PC or an Internet TV 41 which is commercially used in most of family.
Meanwhile, another embodiment of a union remote controller according to the present invention using a general remote controller further includes a display means, an Internet access means, and a communication means for data downloading to a general remote controller itself. Also, it further includes a program for controlling operations of the display, Internet access, and data downloading, thereby enabling direct downloading of remote controller information unlike the embodiment of FIG. 3.
A method for operating a union remote controller information providing system will be explained with reference to FIG. 4. A case based on a mobile communication terminal among examples of a union remote controller according to the present invention will be explained.
First of all, the server (or server operator) 12 of FIG. 1 collects various remote controller information (remote controller code information and function information of electronic apparatuses according to each kind and model) and list information of electronic apparatuses corresponding to the remote controller information. Then, the server stores the information in D/B, updates the D/B periodically, and operates an Internet site for providing remote controller information to a user.
Meanwhile, to download the remote controller information, a user accesses the Internet site by using his or her mobile communication terminal, thereby requesting remote controller information (S41).
Accordingly, the server 12 determines whether a request of remote controller information by a user accessed the Internet site is accepted or not (S42).
Subsequently, if the request of remote controller information is accepted as a result of the determination (S42), the server 12 determines whether the request of remote controller information is performed by a user's direct inputting a model name or not (S43).
Then, as a result of the determination (S43), if a user directly inputs a model name, the server 12 searches remote controller information matching to the model name which the user input to a D/B and obtains (S44).
Subsequently, the server 12 transmits the obtained remote controller information to a user's request means, that is a mobile communication terminal (S45).
Meanwhile, as a result of the determination (S43), if it is determined that the use didn't directly input a model name, the server 12 obtains a list of a corresponding electronic apparatus according to a manufacture company and a model in a D/B and transmits to a user's request means, that is a mobile communication terminal (S46). Accordingly, a user selects an electronic apparatus which he or she wants among lists displayed on his or her mobile communication terminal.
Then, the server 12 obtains remote controller information corresponding to an electronic apparatus which the user selected in a D/B and transmits to the user's mobile communication terminal (S47).
Subsequently, the server 12 determines that a user has finished an access to a site (S48). At this time, if the user has not finished an access, the server waits for another request for code information.
Meanwhile, in case that a user accesses a site through a remote controller having an Internet function, an Internet TV, or a PC not a mobile communication terminal, the aforementioned method for operation a remote controller information providing system is same.
Hereinafter, an operation of a union remote controller (a mobile communication terminal, a remote controller having an Internet access function, a remote controller connected to an Internet TV or a PC) according to the present invention will be explained with reference to FIG. 5.
A user accesses an Internet site which provides the aforementioned remote controller information (code information and function information) by using a mobile communication terminal, a remote controller having an Internet access function, and a remote controller connected to an Internet TV or a PC (S51). At this time, in a remote controller connected to an Internet TV or a PC, an Internet access is impossible by a remote controller itself, thereby accessing an Internet site through an Internet TV or a PC connected to a remote controller.
Then, the remote controller information is required of the Internet site (S52), and downloads remote controller information transmitted from the Internet site (S53). Since the information request and downloading have already been described with reference to FIG. 4, their description will be omitted. Instead, in a remote controller connected to an Internet TV or a PC, it is required that a program for transmitting the remote controller information downloaded from the Internet site to an Internet TV or a PC to a remote controller should be installed. The program can be provided as a diskette type or a downloading type from a corresponding Internet site.
Accordingly, a user downloads remote controller information through an Internet TV or a PC, and transmits the controller information to a remote controller again by using the program. Otherwise, a user directly transmits the remote controller information to a remote controller through an Internet TV or a PC at the time of downloading.
Subsequently, if a user selects a remote controller mode among menus of a mobile communication terminal (S54), screens relevant to a remote controller operation, that is, screens of product lists corresponding to remote controller information which he or she has downloaded until now are displayed on a display window of a mobile communication terminal. Then, if the user selects one of the products shown on the list screen, various remote controller function keys of a corresponding product are displayed (S55).
Then, if a user selects his or her desired key among function keys displayed on the display window (S56), an infrared ray transmitting unit is operated in a controlling unit so as to generate an infrared ray signal having a code fit to the user, thereby a corresponding infrared signal is output (S57).
For example, in case that a user selects a TV remote controller mode of LG and selects a ‘channel+’ function among functions displayed on an LCD window by using up and down keys of a mobile communication terminal, the controlling unit reads a key code corresponding to a ‘channel+’ of a corresponding model TV of LG among the stored remote controller code information by using a preset application program, so that an infrared ray transmitting unit is operated and an infrared ray signal of a corresponding code is transmitted.
Accordingly, a corresponding electronic apparatus receives an infrared ray signal generated from the mobile communication terminal and decodes, thereby performing a corresponding operation.
In the meantime, if a user does not select a remote controller mode in menus of a mobile communication terminal or does not input a predetermined key on a menu, a general mobile communication terminal function is performed (S58).
The aforementioned operation of a union remote controller of a mobile communication terminal is equally applied between a remote controller having an Internet access function and a remote controller not having an Internet access function except an operation which selects a remote controller mode.
The union remote controller, the union remote controller information providing system and the method for using the same have the following advantages.
First, all kinds of electronic apparatuses can be remotely controlled regardless of manufacture companies and product models, etc. Also, products which will be on the market later can also be controlled through a simple Internet access and a downloading without any correction in hardware. Therefore, a separate remote controller for each product is riot required, and there is no temporal and economical inconvenience that may occur in maintaining a number of remote controllers.
It will be apparent to those skilled in the art than various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
