Description

Display device, remote control and related display system

technical field

The present invention relates to a display device, a remote control and a related display system, in particular to a display device, a remote control and a related display that can realize a universal remote control by utilizing the operation resources of the display device and provide a friendly user interface. system.

Background technique

Multimedia information can record various information, ideas, knowledge, activities, events and news with dynamic images and sounds, and display devices that can display multimedia information, such as TVs, screens/monitors and projectors, have become indispensable in modern society One of the electronic devices.

In order to provide a more vivid display quality and a more comfortable and convenient display environment, the display device will work together with various peripheral devices to form a display system. Peripheral devices can include various source devices that can provide multimedia information, such as video tapes, DVD and/or Blu-ray disc players, memory cards/hard disk players, satellite/network/cable and/or wireless TV set-top boxes, video game consoles ( video game console), mobile phone with multimedia output function, computer, camera (camcorder) and video camcorder (camcorder), etc. Peripheral devices can also be auxiliary playback devices, such as stereos, equalizers/amplifiers, and speakers. Another type of peripheral device receives the output of the display device, such as an audio tape, video tape and/or optical disc recorder. Furthermore, the peripheral device may also include various devices that can adjust the peripheral environment of the display device for the user, such as air-conditioning devices, air conditioners/heaters, lights with controlled brightness adjustment, and windows with servo mechanisms that can be controlled to open and close. / Curtains, windows whose transparency can be controlled and adjusted, etc.; if the display device is a projector, the peripheral device can also include a projection curtain that can be controlled to expand or retract.

Modern display devices and various peripheral devices can be controlled by remote control respectively. However, the display device and various peripheral devices each have their own dedicated remote controllers. It is quite inconvenient for users to switch between the dedicated remote controllers. For example, when the user wants to watch the multimedia information in the optical disc in a comfortable environment, the user needs to use the remote control of the optical drive to start the optical drive to start providing multimedia information, use the remote control of the display device to switch the source to the optical drive to display the multimedia information, and / Or use the audio remote control to turn on and adjust the sound display in multimedia information, use the light remote control to adjust or turn off the lights, use the air conditioner remote control to adjust the room temperature, etc.

Although there are universal remote controllers that try to integrate various remote controllers in the display system into one, the current universal remote controllers still have disadvantages. The remote control will set various buttons to represent different remote control commands; in order to let the user know the corresponding function (remote control command) of each button, each button will be displayed with additional graphics, symbols, characters, colors and/or the shape of the button itself As an identification prompt, it is convenient for users to identify. When the universal remote control is used to integrate the dedicated remote controls, the keys of the dedicated remote control will be replaced by the keys of the universal remote control itself. However, the key position configuration and key recognition prompts of the universal remote control will not be consistent with those of the dedicated remote control. Users must adapt/memorize the key position configuration and key recognition prompts of the universal remote control by themselves, and cannot perform universal remote control in a friendly and intuitive way. . The key identification prompts of the dedicated remote control are designed according to the user's intuition; in contrast, the universal remote control can widely support unspecified key definitions, and the identification prompts of each key will be relatively vague and lack features.

Furthermore, it is difficult to change the key recognition prompt of the universal remote controller. For example, although the user can map the power-on buttons of different dedicated remote controllers to different buttons on the universal remote controller, it is difficult to customize the identification prompts of these buttons on the dedicated remote controller, causing the user to operate on the trouble.

Please refer to FIG. 1 , which illustrates a display system 10a according to an embodiment of the present invention. The display system 10 a includes a display device 12 a , a remote controller 14 a and one or more peripheral devices. In FIG. 1 , the peripheral devices PD1 to PD4 are represented. For example, the display device 12a can be a TV, a monitor or a projector, and the peripheral devices PD1 and PD2 can be source devices providing multimedia information, respectively providing multimedia media signals Sm1 and Sm2 to the display device 12a, such as It is said to be a stream carrying dynamic audio-visual multimedia information.

The peripheral device PD4 can be an auxiliary playback device, such as a sound or a loudspeaker, etc.; the peripheral device PD4 can also be a device that can adjust the peripheral environment of the display device for the user, such as a controllable air conditioner, window grille or light, etc. . According to the present invention, the user can use the remote controller 14a to remotely control the display device 12a and the peripheral devices PD1 to PD4, and use the display device 12a as the user interface of the universal remote controller to provide a rich, intuitive and friendly operating environment.

In the display system 10a, the display device 12a includes a receiver 16, a decoder 18, a remote control processing module 20a, an input interface 34, a display processing module 36, a layout recorder 38, a display unit 40 and a output interface 50 . The remote control processing module 20 a is provided with a coordinate calculator 22 a , a graphic generating unit 24 , a command comparator 26 , an indicating module 28 and a transmission generator 30 . The coordinate calculator 22a and the command comparator 26 in the remote control processing module 20 are coupled to the receiver 16 via the decoder 18, and are also coupled to the indication module 28; the indication module 28 is coupled to the transmission generator 30, and then coupled to the transmitter device 32a. The layout recorder 38 is coupled to the coordinate calculator 22 a of the remote control processing module 20 a, and then coupled to the graphics generating unit 24 . The display unit 40 is coupled to the input interface 50 via the display processing module 36 and is also coupled to the graphics generating unit 24 of the remote control processing module 20a.

The remote controller 14a is provided with a transmitter 42a, a transmission generator 44a, a command generator 46a and a coordinate generator 48; the command generator 46a and the coordinate generator 48 are coupled to the transmission generator 44a, and then coupled to the transmitter device 42a.

In the display device 12a, the input interface 34 is coupled to the peripheral devices PD1 and PD2 of the signal source to receive the media signals Sm1 and Sm2. The display processing module 36 is coupled to the input interface 34 and the display unit 40; the display processing module 36 can perform demodulation/data recovery, decoding, decompression and/or various signal processing on the media signal received by the input interface 34, so as to The image carried in the media signal is taken out and displayed on the display unit 40 . The display unit 40 may include a display panel and related control and driving mechanisms. Furthermore, the peripheral device PD3 to receive signals from the display device 12a can be coupled to the output interface 50; the signal processing result of the display processing module 36 can be output as a media signal Sm3 by the output interface 50, and transmitted to the peripheral device PD3.

In the display system 10a of the present invention, the situation of using the display device 12a together with the remote controller 14a to realize the universal remote control and its user interface can be described as follows. In the remote controller 14a, the coordinate generator 48 can be controlled by the user to provide coordinate information; the command generator 46a provides a corresponding command information under the control of the user. For example, the coordinate generator 48 and the command generator 46a can be controlled by the user through the buttons, the touch panel and/or the dial of the remote controller 14a, so as to provide corresponding coordinate information and command information according to the user control. The transmission generator 44a provides an electronic remote control signal Sr0 to the transmitter 42a according to the coordinate information and the command information; for example, the transmission generator 44a can encode/encapsulate the coordinate information and the command information into the remote control signal Sr0. The transmitter 42a can convert/modulate the remote control signal Sr0 into a remote control signal Sr1 and transmit it; for example, the remote control signal Sr1 can be an infrared or radio frequency remote control signal.

In the display device 12a, the receiver 16 can receive the remote control signal Sr1, and demodulate/convert it into an electronic remote control signal Sr2. The decoder 18 decapsulates/decodes the coordinate information and command information carried in the remote control signal Sr2. The command comparator 26 has a plurality of preset remote control commands built in, and can compare the command information in the remote control signal Sr2 with these preset remote control commands. These remote control commands can be the remote control commands of the display device 12a itself, and can further cover the remote control commands accepted by the peripheral devices PD1 to PD4; in other words, each remote control command will correspond to the display device 12a itself or the peripheral devices. one of them.

When the command comparator 26 compares and finds that the command information of the remote control signal Sr2 matches a certain matching remote control command in the preset remote control command, if the matching remote control command is a remote control command of the display device 12a itself, the display device 12a can be based on this matching. The remote control command performs the corresponding operation. On the other hand, if the matching remote control command corresponds to a certain peripheral device, the indicating module 28 will provide the transmission signal St0 according to the matching remote control command, for example, carry the matching remote control command in the transmission signal St0. The transmission generator 30 encodes/packages the transmission signal St0 into a transmission signal St1, and the transmitter 32a converts/modulates the transmission signal St1 into a transmission signal St2, and transmits the transmission signal St2.

In the embodiment of FIG. 1 , the transmitter 32a can implement a signal transmission interface between the display device 12a and the peripheral devices PD1 to PD4 . For example, the transmitter 32a can be an infrared or radio signal transmitter, which transmits the infrared/radio transmission signal St2 to each peripheral device. In this way, the peripheral device corresponding to the remote control command in the transmission signal Sr2 can receive the remote control command and be controlled to perform corresponding operations. For another example, the transmitter 32a can transmit the transmission signal St2 to each peripheral device through a wired or wireless network, so that the corresponding peripheral device can receive the remote control command in the transmission signal St2. In this network, the display device 12a and each peripheral device can be connected to form a network using a star topology or a daisy chain topology. Through the transmitter 42a of the remote controller 14a and the receiver 16 to the transmitter 32a of the display device 12a, the display device 12a and each of the peripheral devices PD1 to PD4 can receive corresponding remote control commands, realizing universal remote control.

In order to provide a richer and more friendly user interface for the universal remote control, the remote control processing module 36 can also provide various remote control layouts to graphically simulate the dedicated remote controls of each peripheral device (and the display device 12a itself), so that the user can continue to use the dedicated remote control Universal remote control with advanced remote control operation concept and intuition. The layout recorder 38 in the display device 12a is used to store/record a remote control layout ML. According to the remote control layout ML provided by the layout recorder 38, the graphic generation unit 24 generates corresponding graphic images, and is displayed to the user by the display unit 40; what the screen 100 in FIG. The remote control layout ML has a coordinate configuration, including one or more coordinate areas, each coordinate area corresponds to one or more remote control commands, and each remote control command is associated with a certain peripheral device (or the display device 12a itself). On the screen presented by the display unit 40 , different positions can be assigned different coordinates, and each coordinate area corresponds to an area on the screen.

For example, the remote control layout ML includes N1 coordinate areas Z(1,1) to Z(1,N1), which are used as the uppermost remote control interfaces of multiple peripheral devices PD1 to PDN, and each coordinate area Z(1,1 ) to Z(1, N) respectively correspond to selection buttons of different peripheral devices, for example, pressing Z(1, 1) can turn on the peripheral device PD1. After opening PD1, then enter the second layer of remote control layout ML, which is used to simulate the key position configuration and identification prompts of its dedicated remote control for peripheral device PD1 (such as a DVD player); each coordinate area Z(1,1) to Z( 1, N1) respectively correspond to a button (or a controllable mechanism) on the dedicated remote controller. Therefore, each coordinate area Z(1, 1) to Z(1, N1) also corresponds to the remote control commands CMD(1) to CMD(X1) that the peripheral device PD1 can receive. For example, the remote control command CMD(1) may be power off, and the remote control command CMD(X1) may be fast forward. And when the remote control layout ML is displayed on the screen 100, each coordinate area can be displayed as a graphic corresponding to the button. For example, the graphic B1 of the button corresponds to the coordinate area Z(1,1), and the coordinate area Z(1,N1) corresponds to the graphic B2, and so on. Similarly, corresponding to the dedicated remote controller of the peripheral device PD2 (such as a set-top box), the remote control panel ML can also include N2 coordinate areas Z(2,1) to Z(2,N2), corresponding to the remote control commands of the peripheral device PD2 CMD(1) to CMD(X2). It can be understood that, in another embodiment, the display device may only have a single-layer remote control panel.

Through the user interface realized by the remote control panel, the situation that the user uses the remote control 14a to perform universal remote control can be described as follows. According to the screen guidance displayed by the display unit 40, the user controls the coordinate generator 48 of the remote controller 14a to generate coordinate information corresponding to a position on the screen; the coordinate information is transmitted to The coordinate calculator 22 a. The coordinate calculator 22 a will let the user know the corresponding position of the coordinate information in the screen 100 through the graphics generating unit 24 and the display unit 40 . For example, the graphic generating unit 24 can provide a graphic of a cursor at a position corresponding to the coordinate information, and the display unit 40 can display it to the user. Or, for each coordinate area of each remote control layout, the coordinate calculator 22a can calculate the coordinate area closest to the corresponding position of the coordinate information, and update the coordinate information into the coordinate area, and the graphic generation unit 24. The graphics corresponding to the coordinate area can be highlighted by methods such as highlighting and dynamic images.

The coordinate calculator 22a of the display device compares the user coordinate information with the coordinate areas of each remote control panel. When the coordinate calculator 22a finds out that the coordinate information matches a certain matching coordinate area, it means that the user intends to trigger the remote control command corresponding to the matching coordinate area. If the remote control command corresponds to a peripheral device, the indication module 28 will provide a transmission signal St1 according to the remote control command corresponding to the corresponding coordinate area, so as to carry the remote control command in the transmission signal St1. Then, the transmitter 32a of the display device can send the transmission signal St2 to each peripheral device according to the transmission signal St1, so that the corresponding peripheral device can be controlled and realize a universal remote control.

In other words, via the remote controller 14a, the user can freely switch among the coordinate areas of the remote control panel ML to remotely control different peripheral devices. Since the remote control layout ML can inherit the key position configuration and identification prompts of the dedicated remote control, the user does not need to accommodate the key position configuration and identification prompts of the remote control 14a. Since the display function and hardware and software operating resources of the display device 12a are far more abundant than those of the remote controller 14a, the present invention uses the existing functions and resources of the display device 12a to replace some functions (such as the user interface) of the universal remote control. to achieve. Since the remote controller does not need to implement a user interface, the present invention can simplify the structure of the remote controller 14a and reduce its cost. Moreover, the display device 12a can further enhance the functions of the universal remote control, making it richer and more diverse, and more in line with the customization needs of users.

For example, the user can enhance the inadequacy of the dedicated remote control on the remote control panel. For example, if the user feels that a certain key of the dedicated remote control is more commonly used, the user can customize its corresponding coordinate area and graphic screen, enlarge it and/or change the identification indication of the graphic (such as changing the color and text) / symbol) to make it more visible and easier to touch. In contrast, buttons that are not frequently used or are not needed can be removed from the remote control panel. The user can also associate each coordinate area of the remote control panel with various corresponding sound effects, further enabling the remote control panel to provide multimedia video and audio control feedback.

With the remote control panel ML, in addition to simulating the dedicated remote controls for each peripheral device, it is also possible to centralize the remote control commands of different peripheral devices (and the display device 12a). For example, the user can concentrate the remote control commands needed to watch movies in the remote control layout ML, and associate its coordinate area Z(n, 1) with a certain remote control command CMD of the peripheral device PD4 (such as an air conditioner) (Xn1) (such as power on), associate another coordinate zone Z(n, 2) with the remote control command CMD(Xn2) of another peripheral device PD1, and so on.

As shown in the screen 100 , the remote control layout ML and the image provided by the display processing module 36 can be combined and displayed on the same screen. If the user has not performed any remote control for a period of time, the remote control processing module 20a can automatically hide the graphics on the remote control panel ML, and re-display the graphics on the remote control panel ML when the user performs remote control again. The graphic transparency of the remote control panel ML can also be adjusted by the user.

In another embodiment, the screen may display a plurality of graphic images of the remote control layout ML(n) for use as remote control layouts of different devices, and the user may also use self-defined text symbols and/or graphics to briefly explain the correspondence of each coordinate area. functions (remote control commands). In other words, the custom remote control layout is similar to a macro, allowing users to centrally organize frequently used remote control commands for different peripheral devices for easy access.

In the embodiment of FIG. 1, the user performs a general remote control via the remote controller 14a, and the transmitter 42a of the remote controller 14a sends out the remote control signal Sr1; the receiver 16 of the display device 12a is matched with the transmitter 42a to receive the remote control signal Sr1. It is the electronic remote control signal Sr2. In another embodiment, the receiver 16 may include an image receiver (such as a light sensor or a video camera), which directly captures the user's action features as coordinate information and/or in the remote control signal Sr2. Command information, allowing users to perform universal remote control with gestures and/or motions. In this embodiment, the physical remote control 14a is no longer needed, and the user can realize the function of a virtual remote control by his own gestures and/or actions. And/or, the receiver may include a sound receiver (such as a microphone), which extracts features from the sound of the user (such as voice or palm clapping sound, etc.) as coordinate information and/or command information, to Universal control for voice activation.

Similarly, the coordinate generator 48 and/or the command generator 46a in the remote controller 14a can also accept the user's actions, gestures, and voice control through the image receiver and/or sound receiver to generate corresponding coordinates. information and/or command information. In some applications, the display device 12a may be far away from the user, and the physical remote control 14a may be placed near the user to capture the user's actions, gestures and/or voice nearby.

Please refer to FIG. 2 , which illustrates a display system 10 b according to another embodiment of the present invention. In the display system 10b, the user can remotely control a display device 12b and various peripheral devices (such as PD1 to PD4) via a remote controller 14b. Similar to the display device 10a in Figure 1, the display device 10b in Figure 2 is provided with a receiver 16, a decoder 18, a layout recorder 38, a display unit 40, a remote control processing module 20b, a transmitter 32b, a display The processing module 36 , an input interface 34 and an output interface 50 . The remote control processing module 20 b is provided with a coordinate calculator 22 b , a graphic generating unit 24 , an indicating module 28 and a transmission generator 30 . A command generator 46 b , a coordinate generator 48 , a receiver 52 and a controller 54 are provided in the remote controller 14 b. The controller 54 is provided with a transmission generator 44 b and a recorder 32 b ; the transmission generator 44 b is coupled to the command generator 46 b , the transmission generator 44 b and the recorder 56 , and the recorder 56 is coupled to the receiver 52 .

The operation of the display system 10b can be described as follows. The layout recorder 38 and the graphics generating unit 24 provide a universal remote control user interface, such as the screen 100 in FIG. 1 ; the user refers to the user interface and uses the remote controller 14b to perform universal remote control. For example, the user can make the coordinate generator 48 provide corresponding coordinate information through the touch panel of the remote controller, the up, down, left, and right direction control buttons and/or the turntable (not shown). The command generator 46b is then built-in various remote control commands that can remotely control the display processing module 36 and the remote control processing module 20b; for example, each remote control command can correspond to each button on the remote controller 14b. The generator 46b provides command information according to the remote control command corresponding to the key. The transmission generator 44b encodes/encapsulates/carries the coordinate information and command information in the electronic remote control signal Sr0, and the transmitter 42b performs necessary conversion/modulation on the remote control signal Sr0 to transmit the remote control signal Sr0 as a remote control signal Sr1 . The remote control signal Sr1 may be an infrared or radio frequency radio remote control signal.

The receiver 16 of the display device 12b receives the remote control signal Sr1 from the remote controller 14a, and demodulates/converts it into an electronic remote control signal Sr2; the decoder 18 decodes/decapsulates the remote control signal Sr2 to obtain the coordinate information and/or command information. Referring to the layout/coordinate area and the corresponding remote control commands and peripheral devices provided by the layout recorder 38, the coordinate calculator 22b compares the user interface that the user wants to display the display device 12b according to the coordinate information and/or command information Click on which icon or name on the screen, that is, what kind of remote control command is to be performed on which peripheral device; and the indicating module 28 will provide a corresponding transmission signal St0 according to the remote control command, and carry the remote control command in the transmission Signal St0. The transmission generator 30 encodes/encapsulates the transmission signal St0 to generate a transmission signal St1. The transmitter 32b converts/modulates the electronic transmission signal St1 into a transmission signal St2 and transmits it. The transmission signal St2 may be a signal of infrared rays or radio (such as radio frequency radio).

After receiving the transmission signal St2, the receiver 52 of the remote controller 14b provides a corresponding electronic transmission signal St3. The recorder 56 correspondingly provides an electronic remote control signal Sr3 according to the electronic transmission signal St3, and the transmitter 42b provides a remote control signal Sr4 (such as infrared or radio remote control signal) according to the remote control signal Sr3, and transmits the remote control signal Sr4 to each peripheral device . In this way, each peripheral device can be controlled by the remote control signal Sr4 to realize universal remote control.

In other words, in the embodiment of FIG. 2 of the present invention, the user still performs universal remote control of the peripheral devices via the remote controller 14b and the display device 12b; the difference from the embodiment of FIG. 1 is that the display device 12b is used to control each peripheral device. The transmission signal St1/St2 of the device is transferred to each peripheral device PD1 to PD4 via the remote control signal Sr3/Sr4 of the remote controller 16b. In some applications, the mutual position arrangement of the display device 12b and each peripheral device may make it difficult for the transmission signal St2 (such as the infrared transmission signal St2) of the display device 12b to be transmitted to each peripheral device; It will be arranged around the user, and there will be a relatively direct and unobstructed signal transmission path between each peripheral device and the remote controller 14b used by the user, and the present invention can use the remote controller 16b to switch the signal transmission path of each peripheral device. remote command.

The remote control signals received by different peripheral devices carry remote control commands in different formats; for example, the remote control signals received by the peripheral device PD1 are encoded/modulated in the first format, and the remote control commands received by the peripheral device PD2 The signal is coded and modulated in a second, different format. When performing universal remote control, the remote control signals to be transmitted to the peripheral devices PD1 and PD2 also conform to the first format and the second format respectively. When the remote control 14b uses the remote control signal Sr4 to transfer the remote control commands of different peripheral devices, one embodiment is to build various remote control signal formats in the transmission generator 44b of the remote control 14b, so that the remote control commands of different peripheral devices can be transmitted. It is carried in the remote control signal Sr4 according to the corresponding format.

In another embodiment of the remote controller 14b, the receiver 52 can capture the waveform characteristics of the transmission signal St2 and respond to the transmission signal St3. The recorder 56 is a waveform recorder, which provides/records a transmission information to the transmission generator 44b according to the waveform characteristic of the transmission signal St2 (such as the waveform sampling of the first transmission signal). The transmission generator 44b is a waveform generator, which enables the transmitter 42b to reconstruct a remote control signal Sr4 identical to the transmission signal St2 according to the waveform characteristics recorded in the transmission information. In this embodiment, when the display device 12b provides the corresponding transmission signal St2 according to the remote control command of a certain peripheral device, the transmission signal St2 has been made to conform to the format of the peripheral device. The remote controller 14b does not need to interpret the remote control command in the transmission signal St2, but only needs to repeat the waveform of the transmission signal St2 in the remote control signal Sr4. Therefore, this embodiment can simplify the construction of the remote controller 14b and reduce its cost.

In another embodiment of the present invention, the user can select the peripheral device to be remote controlled through the remote control interface, and then directly use the remote controller 14b to remotely control the selected peripheral device. The user operates on the remote control 14b referring to the remote control interface displayed on the display device 12b, for example, selects a coordinate area representing a certain peripheral device (one of the peripheral devices PD1 to PD4) on the remote control interface. The remote controller 14b transmits the corresponding coordinate information to the display device 12b through the remote control signal Sr0/Sr1. According to the coordinate information and the coordinate configuration of the remote control page, the remote control processing module 20b analyzes and knows the peripheral device that the user wants to control remotely, and transmits back to the remote control 14b by using the transmission signal St1/St2. In this way, the remote control 14b knows the peripheral device that the user wants to control remotely, and can directly control the peripheral device with the remote control signal Sr4.

For example, if the user wants to remotely control the peripheral device PD1, he can first specify the peripheral device PD1 through the remote control interface, and then the remote controller 14b will become the remote controller of the peripheral device PD1, and the user can directly use the remote controller 14b to remotely control the peripheral device PD1. When the user wants to remotely control the peripheral device PD2, he can specify the peripheral device PD2 through the remote control interface of the display device 12b; under the control of the remote control processing module 20b, the remote controller 14b will become the remote controller of the peripheral device PD2, and the user can The peripheral device PD2 is directly controlled by the remote controller 14b.

In such an embodiment, the remote controller 14b can have built-in various remote control commands and corresponding remote control signal formats and/or waveform characteristics of each peripheral device (such as peripheral devices PD1 to PD4 ), so as to directly control each peripheral device. Or, when the remote controller 14b is to be used as a remote controller of a certain peripheral device, the display device 12b can use the transmission signal St2 to transmit various remote control commands of the peripheral device and the corresponding remote control signal format and/or waveform characteristics to the remote controller 14b, This information is used by the remote controller 14b to remotely control the peripheral device.

Compared with the remote controller 12b, since the display device 12b itself has powerful signal storage/processing functions and hardware and software operating resources, it can easily meet the format requirements of various peripheral devices. For example, the remote control processing module 20b of the display device 12b can have built-in formats corresponding to various peripheral devices, so that the transmission generator 30/transmitter 32b can send the transmission signal St2 of the corresponding format for each peripheral device. And/or, the remote control processing module 20b (and 20a) can record the waveform characteristics of the corresponding remote control signals for various remote control commands of each peripheral device; The corresponding transmission signal St2 is reconstructed from the waveform characteristics of the remote control signal.

In the embodiment in FIG. 2, the remote control signals Sr1 and Sr4 sent by the transmitter 42b may be the same or different remote control signals; for example, the remote control signals Sr1 and Sr4 may both be infrared remote control signals. In another embodiment, the remote control signal Sr1 is an infrared remote control signal, and the remote control signal Sr4 is a radio remote control signal; the transmitter 42b has both infrared and radio remote control signal emitting functions.

In the display system 10b', the display device 12b and the remote controller 14b are used, and one or more adapters are added. In FIG. 3, the adapter 58 is taken as an example. As discussed above, when performing universal remote control, the remote control command to be transmitted from the display device 12b to each peripheral device will be carried in the transmission signal St2, and the remote controller 14b provides the remote control signal Sr4 according to the transmission signal St2. However, in some applications, there is still no better signal transmission path between the remote controller 14b and some peripheral devices, so the adapter 58 can be used to transfer the remote control signal Sr4; the adapter 58 will provide The remote control signal Sr5 enables the remote control signal Sr5 to be transmitted to peripheral devices to achieve the purpose of universal remote control.

In the embodiment of FIG. 3, the adapter 58 is provided with a receiver 52', a recorder 56', a transmission generator 44b' and a transmitter 42b', and its function is the same as that of the receiver 52, Recorder 56, transmission generator 44b is similar to transmitter 42b. In one embodiment, the receiver 52' receives the remote control signal Sr4 and extracts its waveform characteristics, the recorder 56 provides a transmission information to the transmission generator 44b' according to the waveform characteristics, and the transmission generator 44b' and the transmitter 42b' can be The remote control signal Sr5 is reconstructed according to the waveform characteristics of the remote control signal Sr4, and transmitted to each peripheral device. If the transmission range of the remote control signals Sr4 and Sr5 does not cover all peripheral devices, another or more adapters can be added to provide subsequent remote control signals according to the remote control signals Sr4 and/or Sr5, so that the remote control signal Sr4 can be switched to each peripheral device.

In the embodiment of FIG. 3, the remote controller 14b and the adapter 58 have the same signal switching structure, from the receiver 52/52', the recorder 56/56', the transmission generator 44b/44b' to the transmitter 42b/ 42b'. Therefore, the remote controller 14b itself can also be regarded as an adapter.

In the display device of the present invention, the remote control processing module can learn the remote control signals sent by the remote controllers dedicated to each peripheral device, and through the user interface provided by the remote control processing module and the display unit, the user can associate the remote control signals/remote control commands with the Corresponding remote control layout/coordinate area/peripheral device. Take FIG. 2 as an example to illustrate: for the peripheral device PD1, the user can first press a certain button of the dedicated remote controller (not shown), so that the receiver 16 of the display device 12b can receive the corresponding remote control signal sent by the dedicated remote controller. . Then, the user can use the remote controller 14b to perform settings to associate the remote control signal with the corresponding display device, remote control command, remote control layout and/or coordinate area. In one embodiment, the remote control processing module 20b can analyze the format used and the command information carried in the remote control signal sent by the dedicated remote control, and associate the command information with the user's device when the user makes settings. Then, when the user triggers the remote control signal according to the previous settings, the remote control processing module 20b will use the corresponding format to carry the corresponding command information in the remote control signal Sr2. In another embodiment, the remote control processing module 20b extracts and records representative waveform characteristics from the remote control signal sent by the dedicated remote control, and this waveform characteristic can be regarded as the command information of the remote control signal, and is associated with the Then, when the user triggers the remote control signal according to the setting, the remote control processing module 20b can provide waveform characteristics, so that the transmitter 32b can reconstruct the remote control signal in the transmission signal St2.
