Please refer to the embodiment of Fig. 1, in which the architecture of the present invention is shown in block diagram form. As shown in the figure, in this embodiment, the wireless remote control video playback system generally includes: a remote controller 10, a transceiver device 20, a light source 30, and a video player host 40; in addition, the screen 42 is also included in the usual case, but It may be a projection device, a head mounted display, or other display device. The transceiver device 20 can be built in the video player host 40 or an external device, and the light source 30 is also the same. The wireless remote video playback system can be, for example, a television, a video recorder, a hard disk player, a game console, or the like.

In the present embodiment, the internal structure of the remote controller 10 is substantially as shown in FIG. 2A, and mainly includes an optical sensor 11, a first signal processing and transceiver 12, and a first antenna 13. For the internal structure of the transceiver device 20, please refer to FIG. 2B, which mainly includes a second signal processing and transceiver 22, a second antenna 23, and a second connector 21. The first signal processing and transceiver 12 is not limited to being integrated into a single circuit, and may be divided into two circuits: a signal processor and a transceiver; the second signal processing and transceiver 22 are also applicable. For example, in some applications, it is not required to transmit signals to the remote controller 10 from the transceiver device 20, and the transceiver device 20 may only be a receiving device, wherein the second signal processing and transceiver 22 has only a receiving function. The first signal processing and transceiver 12 in the remote control 10 has only a transmitting function.

Referring to Figures 1, 2A and 2B, the operation mode of this embodiment is as follows: First, the light source 30 emits an optical signal to the outside, for example, an infrared signal IR. Next, the optical sensor 11 senses the optical signal to detect the optical sensor. The relative position with the light source, that is, the relative position of the remote controller and the light source, the position information may be two-dimensional (Fig. 1X, Y direction) or three-dimensional (Fig. 1, X, Y, Z direction) information, and according to the The optical signal generates a first electrical signal representing the location information, and is transmitted to the first signal processing and transceiver 12. The first signal processing and transceiver 12 processes the first electrical signal, converts it to the first wireless signal RF1, and transmits it to the transceiver device 20 through the first antenna 13. In the transceiver device 20, after receiving the first wireless signal RF1 from the remote controller 10, the second antenna 23 is converted into a second electrical signal by the second signal processing and transceiver 22, by the second connector 21 and The first connector 41 is transferred to the video player main unit 40. If the transceiver device 20 is built into the video player host 40, the first connector 41 and the second connector 21 may not be needed.

Fig. 3 shows another embodiment. In the present embodiment, the light source 30 is mounted on the remote controller 10, and the optical sensor 11 is mounted on the transceiver 20. The circuits of the corresponding remote controller 10 and transceiver 20 are shown in Figures 4A and 4B, respectively. Wherein (see Figure 4A), the light source 30 may not have any connection to other circuitry within the remote control 10. The advantage of this embodiment is that the determination of the location information is processed in the second signal processing and transceiver 22, so that the first signal processing and transceiver 12 in the remote controller 10 can be relatively simple, and is transmitted and received from the remote controller 10. The amount of signals transmitted by device 20 is also low.

In one of the applications of the present invention, the user can generate control information by moving the remote control 10 in a three degree space, for example to control the cursor 43 or other subject on the screen 42 (or other type of display device). Control the movement of the object to click on the image 44 and the like. As described above, the relative position information of the remote controller and the light source can be known in the present invention, so that the displacement, the speed, and even the acceleration can be calculated according to the position information at different time points and the time difference therebetween. The above calculation can This is done in the first signal processing and transceiver 12, in the second signal processing and transceiver 22, or in the host 40. The image displayed on the screen 42 according to the present invention may be a super high resolution (Full HD) picture. Moreover, the "controlled object" is not limited to a pointing symbol such as a cursor, and may be other forms of controlled objects, such as a protagonist in a game or a weapon tool used therein.

In the present invention, the user can perform various predetermined functions by using one or more buttons on the remote controller 10, for example, clicking on the image 44 to activate a certain software or function, or clicking on a controlled object and cooperating with the mobile remote controller 10 You can perform different functions by dragging the controlled object, etc., and the same button can accept different functions by clicking or double-clicking. (Of course, you can define more hits for other different functions. In this manual, three hits are called "complex strikes". Differentiate). It should be noted that, unlike the general mouse, the user moves the remote controller 10 in a three-dimensional space instead of moving on the desktop as a general mouse, so when the user presses the button, the remote control is also performed. The position information of the device 10 is changed. When the user presses the button with the remote controller 10, it may be desirable to output position information (for example, when it is necessary to drag the controlled object to move), or it may not want to output the position information to avoid deviating from the desired position (for example, when Click or double-click when starting a feature). Therefore, it is necessary to distinguish and provide solutions.

Please refer to Figure 5A, where the "action output" waveform indicates that the position information (X, Y, or X, Y, Z dimension information) is output at a certain clock, and the "button output" waveform indicates that the output "button is pressed and released" Information, commonly used cases include clicks and double clicks, but the concept of the invention of course also includes buttons that are pressed more quickly and continuously. As can be seen from the figure, if the position information is output at the same time as the "button press" information is output, there is a possibility that it may be deviated from the position selected by the user.

In response to this problem, the present invention provides several solutions as follows:

(1) For the first method, please refer to Figure 5B-5D. When the button is pressed, the "button press" information (click, double click or combo) is output, but the overall circuit suspends outputting position information. For example, the optical sensor 11 is disabled, or the optical sensor 11 is still operating, but the first or second signal processing and transceiver 12 or 22 does not process the first electrical signal generated by it, or In the illustrated embodiment, the remote controller 10 does not transmit location information to the transceiver device 20, or still outputs location information, but does not process it (e.g., does not move the controlled object with changes in location information) and the like. The mode shown in FIG. 5B is: the output of the position information (or output but not processed) is stopped within a critical time T1 after the button is first pressed. The way shown in Fig. 5C is: within a critical time T1 after the last press of the button, the output of the position information is stopped, or the output is not processed. The way shown in Fig. 5D is: stop outputting position information within a critical time t after the last release of the button, or output but not process. The 5B-5D diagram differs in the manner in which the critical time is calculated, but all belong to the concept of the present invention.

In the above modes 5B and 5C, if the user desires to output position information when the button is pressed (for example, when it is necessary to drag the controlled object to move), as shown in FIG. 5E, the user can keep pressing the button. By exceeding the critical time T1, the position information can also be output when the button is pressed.

In the above 5D mode, if the user wants to output the position information when the button is pressed, as shown in FIG. 5F, a critical time T2 can be set in the system, and the calculation is performed from the button press. When the lower button exceeds the critical time T2, the position information is output.

(2) The second mode is that when the button is pressed, in the first or second signal processing and transceiver 12 or 22 (or an additional arithmetic circuit is provided), the remote controller The displacement acceleration of 10 is calculated and judged; when the displacement acceleration of the remote controller 10 is greater than a preset value, it indicates that the user intends to press the button without intention to move the controlled object, and the position information is not output at this time, or the output is not output. Location information is not processed, but only the output of the button is processed. On the other hand, if the acceleration of the remote controller 10 is less than the preset value, the position information is still output and processed. In this mode, there is no need to calculate the critical time for the button to be pressed or released; if the user wishes to drag the controlled object to move, the button can be pressed with less force and the remote controller 10 can be moved, and the system will continue to output (and process). Location information.

(4) The third mode is shown in Fig. 5G. Since the amount of movement of the remote controller 10 caused by the user when the button is clicked is generally low, and is high when double-clicking or combo, it can be on the remote controller 10. Set a dedicated double-click button that, when clicked, double-clicks (or defines it as a combo). In this manner, if the user wishes to drag the controlled object to move, other dedicated or non-dedicated buttons may be used. This third mode can be used alone or in combination with the first and second modes described above.

In some applications, it is necessary to continuously output multiple button presses of "button press". In this case, please refer to Figure 6A. If a button is pressed for a single click, the user may be very tired, even if Figure 5G shows a double click with a single press of the button, and the user may still need to press the button multiple times. According to the present invention, a continuous stroke can be indicated by pressing a button as in Fig. 6B. When the button is pressed, the remote controller 10 will continuously output a plurality of press-and-release operations until the user releases the button. For example, when a user plays a shooting game, the button can be used as a continuous launch function to increase the fun of the game. This button may be the button of the aforementioned 5B-5G diagram or a continuous output dedicated button additionally provided on the remote controller 10.

Please refer to Figures 1, 2A and 2B (the 3rd, 4th and 4th pictures are also the same). In one embodiment of the present invention, the remote controller 10 can receive external audio and transmit it to the video player host 40 via the first wireless signal RF1. The remote controller 10 receives external audio, for example, by setting a microphone MIC on the remote controller 10, or connecting the remote controller 10 with an external microphone MIC, and converting the audio received by the microphone MIC by an analog-to-digital conversion circuit (ADC) 15. After being a digital signal, it is transmitted to the first signal processing and transceiver 12 for processing, and then transmitted to the video player host 40 by the first wireless signal RF1. The audio received by the microphone MIC can be used as a karaoke or as a voice control, such as controlling the video player host 40 to turn on, power off, turn the stage, or adjust the volume; in the latter case, the voice recognition method can be used to judge The instructions can also distinguish the instructions according to simple methods such as volume, audio, number of sounds, etc. without complicated speech recognition.

In another embodiment of the present invention, the remote controller 10 can receive an external image and transmit it to the video player host 40 via the first wireless signal RF1. In this way, the remote controller 10 can have the function of a baby monitor, for example, allowing parents in the living room to monitor the baby's movement in the game room. In the embodiment of the first, second, and second embodiments, the optical sensor 11 is provided in the remote controller 10, so that it is not necessary to provide another external image receiving device, and the optical sensor 11 can be used to sense the infrared signal. With general images. When the monitor function is not required, the optical sensor 11 receives an external optical signal through an IR pass filter to sense the infrared signal emitted by the light source 30. The infrared pass filter can be used in various forms, for example, a high pass filter, which allows infrared rays to pass through but filters out other light, or is a band pass filter, and is only made to be the same as the light source. Light from the band passes but filters out other light. When the monitor function is required, the optical sensor 11 does not transmit infrared rays. The filter directly receives the general image, or does not pass through the infrared high-pass filter or the band-pass filter, but receives the general image through other forms of filters (such as the IR cut filter). The hardware implementation of the above may be referred to, for example, in FIGS. 7A and 7B, by providing different optical paths (such that the optical sensor 11 transmits light through or through the infrared pass filter 16), or by mechanically moving the The infrared pass filter 16 (which causes the infrared pass filter 16 to shield or not shield the optical sensor 11) is achieved.

In still another embodiment of the present invention, the video player host 40 can further transmit information from the video player host 40 to the remote controller 10 via the second radio signal RF2, thereby achieving the function of bidirectional transmission. For example, the video player host 40 can transmit the music to the remote controller 10 via the second radio signal RF2, and is converted by a digital analog conversion circuit (DAC) or a pulse width modulation circuit (PWM) 15 through the speaker SP. Play. In this way, the user can listen to the music through the earphone or directly via the speaker SP. In addition, the video player host 40 may further include a search button (not shown) for searching the remote controller 10. When the user presses the search button, the video player host 40 can use the second radio signal. The RF2 transmits a signal to the remote controller 10, causing the remote controller 10 to vibrate, flash, or play its built-in sound effects. At the same time, it is of course also possible to provide a display function on the host 40 during the search, for example, to provide an LED and to flash it, or to provide a small-sized display 45 (see Fig. 1 or Fig. 3), for example, an LED array or a small The LCD screen displays text or images on the screen or directly on the screen 42 to display information related to the search.

In still another embodiment of the present invention, the video player host 40 can be connected to an Internet, and the remote controller 10 and the video recorder host 40 can communicate with the second wireless signal RF2 through the first wireless signal RF1. VoIP The function.

Moreover, other functions can be further integrated in the remote controller 10. For example, please refer to FIG. 2A or FIG. 4A. The display device 17 can be set in the remote controller 10, for example, a small-sized liquid crystal screen or an LED array to display various information such as volume, Channel, input source (television or video input terminal), etc.; touch input device 18 can also be provided for handwriting input, control cursor movement, or input other commands, messages, etc., the input mode can be optical mode or resistance / Capacitive sensing method.

The present invention has been described with reference to the preferred embodiments thereof, and the present invention is not intended to limit the scope of the present invention. For example, the video player main unit 40 is not limited to being connected to only one remote controller 10, and may be connected to a plurality of remote controllers 10 at the same time, for example, as a platform for a plurality of users to simultaneously compete for each other. For example, in addition to optically generating three-dimensional information, it is also possible to optically generate two-dimensional information, and then use gravity or acceleration sensors to generate third-dimensional information, and the like. All such equivalent variations are intended to be included within the scope of the invention.
