- As generally known in the art, a remote controller refers to a device for controlling an instrument or a machine from a distance. Many currently available electronic products are provided with a remote controller. A user can control various functions of an electronic product using a remote controller from a distance, without the need to directly operate the product. In most cases, however, different remote controllers are used to control different kinds of electronic products or the same kinds of electronic products of different manufacturers. In other words, the user can control only a single product using one remote controller. Different remote controllers should be used according to the kinds of electronic products, such as an audio system and a video system, and the manufacturers of the products. Accordingly, when a remote controller for a particular electronic product of a particular manufacturer has been lost, the user typically must purchase a new remote controller for the same product. Also, users can be inconvenienced when urgently seeking a lost remote controller for operating a particular electronic product.
- Accordingly, the present invention has been made to solve the above-mentioned problems. One object of the present invention is to provide a portable terminal and a method for remote control of electronic products, regardless of the kinds or manufacturers of the products. Another object of the present invention is to provide a method for enabling communication during the remote control of electronic products using a portable terminal.
- In order to accomplish the above objects, embodiments of the present invention provide a method for remote control of electronic products using a portable terminal, said method comprising the steps of performing a remote control of functions of the electronic products in a remote control mode; when communication is tried during the remote control mode, terminating the remote control mode and displaying the communication standby state to provide a communication service upon a user's selection; and when the communication ends, returning to the remote control mode.
- In accordance with another aspect of the present invention, there is provided a method for performing a remote control in a remote control mode of a portable terminal, said method comprising the steps of displaying the kinds of electronic products controllable by a remote controller; displaying the manufacturers of the electronic products; selecting at least one kind of the displayed electronic products; selecting at least one of the displayed manufacturers; setting a remote control mode suitable for the selected electronic product of the selected manufacturer; performing a remote control function in the remote control mode; and terminating the remote control mode to terminate the remote control function.
- In accordance with still another aspect of the present invention, there is provided a portable terminal for remote control of various functions of electronic products, which comprises a display section for displaying the kinds and manufacturers of electronic products controllable by a remote controller; a generalized programming input/output port for oscillating a remote control pulse according to a selected manufacturer; an infrared (IR) modulating/sending section for modulating the oscillated remote control pulse to an infrared ray and sending the infrared ray; and a control section for determining whether communication is tried during implementation of a remote control function, terminating the remote control function to implement a communication function when the communication is initiated, and performing the remote control function again when the communication ends.
- The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawing figures, in which:
FIG. 1 is a block diagram of a portable terminal having a remote control function according to a first embodiment of the present invention.FIG. 2 is a flow chart showing a process of performing a remote control function in a portable terminal according to the first embodiment of the present invention.FIG. 3 shows the information displayed on a display section of a portable terminal according to the first embodiment of the present invention.FIG. 4 is a flow chart showing a process of performing a remote control function in a portable terminal according to a second embodiment of the present invention.FIG. 5 is a flow chart showing the operation of a control section of a portable terminal to perform a communication function during a remote control mode according to the first embodiment of the present invention.FIG. 6 shows the function of a key input section of a portable terminal according to the first embodiment of the present invention.- Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawing figures.

Referring toFIG. 1 , anRF section 110 performs a communication function of a portable terminal TheRF section 110 comprises an RF transmitter for performing upward conversion and amplification of the frequency of a signal, which is being transmitted, and an RF receiver for amplifying a signal, which is being received, with low noise and performing downward conversion of the frequency of the signal. Adata processing section 109 comprises a transmitter for coding and modulating a signal which is being transmitted and a receiver for demodulating and decoding a signal which is being received. Thedata processing section 109 may be composed of a modem and a codec.- An
audio processing section 107 reproduces an audio signal outputted from thedata processing section 109 or transmits an audio signal generated from a microphone to thedata processing section 109. Akey input section 103 is provided with keys for inputting numbers and characters and function keys for setting up various functions. - According to embodiments of the present invention, the functions keys may refer to a remote controller setting key, a product setting key, a product selection key, a manufacturer setting key, a manufacturer selection key, an OK key, a cancel key and so on. The functions keys may include a navigation key for moving a cursor on the display, a selection key, an OK key for confirmation, a cancel key for cancellation, and so on. As will be appreciated by those of ordinary skill in the art, it is possible to implement a particular function by pressing a combination of two or more function keys.
- A
memory 105 may be composed of a program memory and a data memory. The program memory includes programs for controlling general operations of the portable terminal. The data memory stores information for performing a remote control function according to embodiments of the present invention. Also, the data memory can temporarily store data generated during implementation of the above programs. - A
control section 111 controls the overall operation of the portable terminal. As will be understood by those of ordinary skill in the art, thecontrol section 111 may optionally include thedata processing section 109. Thecontrol section 111 may also include a generalized programming input/output port (“GPIO port”). The GPIO port generates a frequency, for example, in the range of 30 KHz to 60 KHz. When provided outside of thecontrol section 111, the GPIO port can be connected to an inside element of the portable terminal The GPIO port oscillates a remote control pulse suitable for the selected kind and manufacturer of electronic product in accordance with a key signal inputted from thekey input section 103.
