The disclosed embodiments relate to methods for programming a universal remote control device.
A universal remote control (URC) device transmits operational signals to control one or more electronic consumer devices such as TVs, VCRs; set-top boxes, audio home theatre systems, and CD/DVD players. A particular brand and make of electronic consumer device responds to operational signals containing a particular set of keycodes and performs the corresponding functions. In order to provide the functionality of a URC device, various types of keycodes are stored in codesets as a codeset database format. Each codeset is identified by a three digit codeset identifier associated with a particular brand and make of electronic consumer device. A URC device generally stores hundreds of codesets in a codeset database and is programmed to use one particular codeset to control one particular electronic consumer device.
Typically, a user is provided with a manual which includes a list of codeset identifiers corresponding to various electronic consumer devices. The user uses the manual to determine the correct codeset identifier corresponding to each electronic consumer device to be controlled, and then manually enters that codeset identifier into the URC device. This process is tedious and time-consuming. Further, if the manual of for the URC device is lost, then the user will have no way to program the URC device except by obtaining another manual (for example, from the manufacturer or by calling customer service center to get programming instructions). In addition, the codeset that may be selected for use by the URC device is limited to the codesets stored in the codeset database and provided in the manual. The URC device needs a relatively large amount of memory to store the entire codeset database and providing this large amount of memory increases the cost of the URC device.
Some URC devices have the capability of being programmed without requiring the user to enter a codeset identifier manually. This type of URC device is typically able to operate in an “auto search” mode such that the user does the auto search to find the desired codeset. However, auto search requires the user to take multiple programming steps to set up the auto search. Scanning through the entire codeset database is also time-consuming. Thus, a market exists for a universal remote control device that can be easily programmed, whereby a user will not need to determine a codeset identifier from a user manual.
A universal remote control (URC) is programmed to control a particular type and make of electronic consumer device using a graphical user interface. In one embodiment, a user interface is displayed on a display screen. The user interface includes a plurality of images which are digital photographs of electronic consumer devices or remote control devices that are used to control the corresponding electronic consumer devices. The digital photographs are displayed in a prioritized order based on market popularity of the corresponding electronic consumer devices. A user views the display screen and selects the digital photograph of the particular type and make of electronic consumer device to be controlled (or its corresponding remote control device that is to be programmed). Codeset information associated with the selected device is outputted to the URC such that the URC is programmed to control the selected device.
An exemplary device comprises a memory, and a processor for executing an image-selection routine that displays a plurality of images on a display screen and outputs codeset information in response to a selection of one of the plurality of images. Each image of the plurality of images is a digital photograph of an electronic consumer device or a remote control device usable to control the electronic consumer device. In one example, the digital photographs of the plurality of images are stored in the memory as compressed digital image files. In another example, the digital photographs are received from a centralized location such as a central cable network.
The selected image corresponds to the particular type and make of electronic consumer device to be controlled by the URC. Codeset information is either a codeset identifier or a codeset associated with the selected device. In one embodiment, the codeset information is transmitted to the URC though an audio connection. By providing an audio connector in the URC, the URC can receive the codeset information across the audio connection and is automatically programmed to control the selected device. In another embodiment, the codeset information is a codeset identifier and is displayed on the display screen. The user views the codeset identifier (for example, a three-digit code) on the display screen, and then manually enters the codeset identifier into the URC to program the URC to control the selected device.
In one advantageous aspect, besides the codeset information, device information including device description information and device behavior characteristics information can also be transmitted to the URC through an audio connection.
Other embodiments and advantages are described in the detailed description below. This summary does not purport to define the invention. The invention is defined by the claims.
The accompanying drawings, where like numerals indicate like components, illustrate embodiments of the invention.
Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.
After the user selects device type DVD and brand name SAMSUNG, a second selection menu of user interface 40 is displayed on display screen 30 (step 52 of
In the example of
There are thousands of electronic consumer devices and remote control devices available on the market. Each device is represented by a digital photograph which is stored as a digital image file. In the example of
For some popular electronic device types and brands, there may be many pages of digital photographs to, be displayed. For instance, there may be dozens of different models of televisions are manufactured by Toshiba. It is therefore time consuming for the user to browse through all the pages of the second selection menu and select the right photograph. One way of improving the second selection menu is to prioritize each photograph based on market popularity of the corresponding device and to display the photograph in the order of its priority. Market popularity of a device is measured by number of unit sales, consumer rating, and other factors. The most popular models of the electronic consumer devices are then displayed first in the front page, thereby reducing the amount of time generally required by a user to select the proper digital photograph.
After the user confirms the selection of SAMSUNG DVD HD841, PC 3 sends (step 54 of
In another example, codeset information 43 is the actual codeset of SAMSUNG DVD HD841. Instead of sending the codeset identifier, PC 3 sends the actual codeset of SAMSUNG DVD HD841 to URC 2. In this example, URC 2 does not need to store the entire codeset database 23 in memory 22. Instead, URC 2 receives the codeset from PC 3 and is programmed to use the codeset to control DVD HD841. The advantage of this method is that it saves memory space and reduces the cost of URC 2. URC 2 only needs to have enough memory to store one or a small number of codesets, as opposed to an entire database of codesets.
The above illustrated method is convenient because URC 2 is programmed automatically after the user selects the photograph of the electronic consumer device or its corresponding remote control device. However, a typical hand held remote control device is only capable of one-way transmission, i.e., it only emits operational signals to control electronic consumer devices. In order to receive codeset information 43 automatically, URC 2 has to be able to do two-way communication. In the example of
This extra cost in receiving codeset information 43 is eliminated in the following example. As illustrated in
In the example of using a set-top box 103, the method of configuring URC 102 is the same as described above with two differences. First, image-selection routine 114 is stored inside set-top box 103. Processor 112 executes image-selection routine 114 and displays user interface 110 on TV 106 (sometimes TV 106 contains a built-in set-top box 103). The user then uses remote control 107 to make selections. In some situation, set-top box 103 contains a key interface 117, and the user used key interface 117 to make selections. Second, digital images 143 are not uploaded from a DVD disc. If set-top box 103 is a satellite set-top box, then digital images 143 are received from satellite 140 through satellite dish 141. If set-top box 103 is a cable set-top box, then digital images 143 are received from a central cable station 142 through a cable network. Therefore, this method eliminates the need of providing local storage of all the digital images or of an extra DVD disc for the user to configure URC 102.
URC 102 is not necessary a hand held remote control device. In one example, URC 102 is embedded inside set-top box 103. URC 102 is programmed the same way as illustrated above. The only difference is that codeset information 153 is internally transmitted to URC 102 within set-top box 103. After URC 102 has been programmed to control a particular electronic consumer device, set-top box 103 acts like an IR blaster to send out operational signals to control that particular electronic consumer device.
In one advantageous aspect, microcontroller 130 of URC 102 includes an on-chip analog-to-digital converter. The analog-to-digital converter is provided in the integrated circuit design of microcontroller 130 for use in other high-volume microcontroller applications (non-remote control device applications) of the microcontroller integrated circuit design. An analog input terminal of the microcontroller integrated circuit that is coupled to the input of the analog-to-digital converter is coupled to RCA jack 133 without substantial other interfacing circuitry between the microcontroller integrated circuit and the RCA jack. The analog-to-digital converter receives the signal on RCA jack 133, digitizes it, and the processor within microcontroller 130 analyzes the digitized information and recovers codeset information 153. Accordingly, the only significant cost that is added to the prior manufacturing cost of universal remote control 102 is the cost of providing the relatively inexpensive RCA jack 133. RCA audio OUT jacks are already customarily supplied on DVD players and set-top boxes and home theatre systems and therefore do not represent an added cost to the typical user. The RCA jack and cable mechanism of communicating codeset information therefore is a very inexpensive way of providing the user with a new ability to download codeset information automatically into a remote control device.
Furthermore, the illustrated method of programming a universal remote control device is not limited to outputting codeset information. In the example of
Although certain specific exemplary embodiments are described above in order to illustrate the invention, the invention is not limited to the specific embodiments. Accordingly, various modifications, adaptations, and combinations of various features of the described embodiments can be practiced without departing from the scope of the invention as set forth in the claims.
