The present invention relates to a remote control apparatus, and more particularly to a programmable remote control apparatus capable of setting its remote control contents and a method thereof.
As information technology advances and electronic industry blooms, various different high-tech products are derived from computers and electronic devices are developed rapidly, and these products bring tremendous convenience to our life. At present, electronic technologies are developed and advanced constantly, and thus people have increasingly higher demand on different types of electronic consumer products. Particularly, wireless technology becomes very popular in recent years, and all kinds of equipments or electronic appliances such as automobiles, refrigerators, and televisions are equipped with a wireless control device for reducing the operating time, so as to achieve the effects of lowering the operating cost and enhancing the operating convenience.
Referring to
For example, the conventional remote control apparatus and electronic device are a television remote controller and a television respectively. If a user wants to turn on the television, the user can press a press key corresponding to the power on of the television remote controller, and then press another press key to operate the television (such as power on/off, adjust the volume, or select a channel, etc) without walking near the television. Users simply press the press keys installed on the remote controller to operate the television, and thus the remote controller brings tremendous convenience to users. However, remote controllers usually have the following problems after it has been used for a period of time:
1. For the same electronic device, only a corresponding remote controller can be used. If the remote controller is missing or damaged, users have to buy the same type of remote controller. Sometimes, such remote controller has been phased out for a long time, and users may be unable to get the remote controller for the electronic device, and they may choose to buy a new television.
2. The press keys of the remote controller may have poor contacts or damages when they get dirty or are operated improperly.
If a remote controller has any of the aforementioned problems, the remote controller will become inconvenient and adversely affect the manufacturers of the electronic products. Therefore, some manufacturers (including Trans Electric Co., Ltd., Website: http://www.px.com.tw/) developed a universal remote controller (such as Trans Electric's RC-500 universal remote controller), and the universal remote controller builds in a remote controller encoding table for various models of different brands of different electronic products (including television, air-conditioner, DVD player, and other home electric appliances) in advance, so that users can search the appropriate remote controller encoding table according to the corresponding brand, model and product type, or users can use “auto-search setup”, “code setup” or “home appliances interchangeable operation” for the setup. Such arrangement determines the key pulse generated by a matrix circuit when each press key of the universal remote controller is pressed, and the encoding unit generates a corresponding code according to one of the product encoding tables, so that the universal remote controller can carry out the remote-controlled operation for at least one product.
However, various different brands of electronic products are introduced constantly to the market, and the encoding tables of the universal remote controller is very limited, and thus the universal remote controller cannot perform the remote-controlled operation for all electronic products, or the press keys of the universal remote controller are limited and cannot cover all required functions of different electronic products. In other words, the universal remote controller cannot output all remote-control signals of the home electric appliances and cause tremendous inconvenience and troubles, even if a universal remote controller has the encoding tables of different remote controllers, but the remote controller encoding tables are not updated. In view of the problems on the use of universal remote controllers, some manufacturers developed a smart remote controller, such as Logitech's Harmony 882 and Harmony 552, and Sony's RM-LJ304, and RM-AX4000. The smart remote controller is a learning remote controller that comes with programmable operating functions for receiving and memorizing remote-control signals issued by traditional remote controllers, and matches a received remote-control signal with a learning press key of the learning remote controller, so that the learning remote controller can learn the remote-control signal corresponding to the learning press key. Thereafter, the learned remote-control signals can be enabled by pressing the learned press keys. For example, Logitech's Harmony 882 and Sony's RM-LJ304 and RM-AX4000 remote controllers come with a touch screen with a plurality of touch learning keys to increase the insufficient number of press keys of the universal remote controllers, but these smart remote controllers still have the following shortcomings:
1. The selling price of a general universal remote controller ranges from USD3 to USD10, but Sony's RM-LJ304 learning remote controller is sold at a price over USD150. There is a huge price gap, since the manufacturing cost of a touch screen is very high. In addition, the learning remote controller requires an additional software design to define and layout all of the touch learning keys on the touch screen, and the cost for the software design and development is high as well, and thus the selling price of these remote controllers remains so high.
2. The smart learning remote controller has a touch screen comprised of many different components, such that after the smart remote controller has installed the touch screen, the height of the smart learning remote controller becomes much higher than the traditional remote controller, and the volume of the smart learning remote controller becomes large, and such increase is unfavorable to the present trend of developing products with a short, small, thin and light design.
As to the smart learning remote controllers with mechanical keys, the remote controller includes a casing having a plurality of mechanical learning keys, and a plurality of words separately printed at the bottom of the casing and proximate to the mechanical learning keys to indicate the represented remote control function, and memorizing the functions to the corresponding mechanical learning keys. Although these remote controllers do not have the aforementioned shortcomings of a smart remote controller with a touch screen, their applications still have the following problems:
1. The words are printed at the bottom of the mechanical learning keys and cannot be altered by users.
2. Most of the words printed at the bottom of the mechanical learning keys come with a number of remote control functions to meet user's requirements, but the printed words are too small and unreadable by users with poor eyesight.
3. User may find insufficient number of press keys for their application, and they usually set irrelevant functions corresponding to the words printed at the bottom of the mechanical learning keys. If another user is using the learned remote control functions which have not been set for the mechanical learning keys, the user may mistaken that the mechanical learning keys are defined with the remote control functions indicated by the words printed at the bottom of mechanical learning keys, or may even forget such remote control functions, and all of the above cause inconvenience and troubles to the use of a smart remote controller with mechanical keys.
In summation of the description above, a conventional remote controller, a smart remote controller with a touch screen, or a smart remote controller with mechanical keys generally has the aforementioned problems. Therefore, users would like to have a remote controller that can overcome the shortcomings of different types and models of remote controllers.
In view of the foregoing shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a programmable remote control apparatus and a method thereof, in hope of overcoming the shortcomings of the prior art and contributing its innovation to the general public.
It is a primary objective of the present invention to provide a remote control apparatus for setting remote control contents, and the remote control apparatus comprises a casing having a plurality of function key modules, a setup key, two display units, two switching key modules, each corresponding to one of the display units, a function key module for setting remote control contents, and a plurality of switching keys disposed around each display unit. The casing installs a circuit board therein and a control unit on the circuit board for connecting each display unit, switching key module and setup key and function key module. After the setup key of the remote control apparatus is triggered to enter into a setting mode, the control unit displays the user-defined content information at a position proximate to the switching key on the display unit and records the user-defined content information and the corresponding switching key code, and then defines the remote control content for each function key module corresponding to at least one switching key, and records the remote control content into the remote control apparatus. Therefore, users can distinguish the switching keys, their represented content information, and different operation instructions of the function key modules corresponding to different switching keys.
Another objective of the present invention is to provide a method of setting remote control content applied to a remote control apparatus having two display units, and the method comprises the steps of: letting the remote control apparatus provide user-defined content information represented by the switching key installed on the remote control apparatus and corresponding to different display units; displaying the user-defined content information on the display unit and at the position proximate to each switching key; recording the user-defined content information and their corresponding switching key codes into the remote control apparatus; providing the remote control contents represented by the function key module installed on the remote control apparatus for defining each switching key; and recording the function key module corresponding to at least one switching key into the remote control, after each operation instruction is defined.
To make it easier for our examiner to understand the objective, technical characteristics and effects of the present invention, a preferred embodiment will be described with accompanying drawings as follows:
