Description

[[Technical Field]]

[0001] The present invention relates to a control device, and particularly to a control device capable of supporting video output. [[Background Art]]

[0002] Handheld devices have the characteristic of being easy to carry during operation. However, for some users, the performance of the control function of the handheld device itself does not meet individual needs, so control devices that can be combined with handheld devices are commercially available. Due to its mechanical design, such a control device can maintain the convenience of portability even when the control device and the handheld device are combined integrally. [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0003] Therefore, users who value control convenience (e.g., game players) can perform input control corresponding to the handheld device through the control interface provided by the control device itself when the aforementioned control device is combined with the handheld device. However, since the display screen of the handheld device is limited by the size of the main body, the visual effect of the handheld device is limited during overall operation.

[0004] The technical problem to be solved by the present invention is, in consideration of the drawbacks of the prior art, to provide a control device capable of supporting video output. [[Means for Solving the Problem]]

[0005] Embodiments of the present invention provide a control device capable of supporting video output, comprising a transmission interface and a control circuit. The transmission interface has a first transmission port and a second transmission port. When a handheld device is connected to the first transmission port, the control circuit acquires first input power supplied from the handheld device via the first transmission port. When a first external device is connected to the second transmission port, the control circuit recognizes the first external device. When the control circuit recognizes the first external device as a display device, the control circuit controls the first input power to be output to the second transmission port in order to supply power to the display device, acquires a display signal from the handheld device via the first transmission port, controls the display signal to be output to the display device via the second transmission port for display. When the control circuit recognizes the first external device as a charging device, the control circuit stops receiving first input power, acquires second input power supplied from the charging device via the second transmission port, and controls the second input power to be output to the first transmission port in order to supply power to the handheld device.

[0006] Embodiments of the present invention provide a control device capable of supporting video output, comprising a transmission interface and a control circuit. The transmission interface has a first transmission port, a second transmission port, and a third transmission port. When a handheld device is connected to the first transmission port, the control circuit acquires first input power supplied from the handheld device via the first transmission port. When a first external device is connected to the second transmission port and a second external device is connected to the third transmission port, the control circuit recognizes the first external device. If the control circuit recognizes the first external device as a charging device and the second external device connected to the third transmission port as a display device, the control circuit stops receiving first input power, acquires second input power supplied from the charging device via the second transmission port, and controls the second input power so that it is output to the first transmission port to supply power to the handheld device and to the third transmission port to supply power to the display device. The control circuit acquires a display signal from the handheld device via the first transmission port, controls the display signal, and outputs it to the display device via the third transmission port for display.

[0007] As described above, the control device that supports video output according to the embodiment of the present invention, when used in combination with a handheld device, can display the display screen of the handheld device on an external display device connected to the control device, and can also be connected to various external devices according to usage needs, thereby improving the convenience of using the control device.

[0010] Embodiments of the present invention will be described below with reference to specific examples. Those skilled in the art will be able to understand the advantages and effects of the present invention from the disclosed information. The present invention can be carried out or applied through other different specific embodiments, and the various detailed descriptions herein can be modified and changed in various ways without departing from the spirit of the invention, based on different viewpoints and uses. It should also be noted in advance that the drawings of the present invention are for illustrative purposes only and are not based on actual dimensions. The technical details of the present invention will be described in more detail using the following embodiments, but the disclosed information is not intended to limit the scope of protection of the present invention.

[0011] In this specification, terms such as “first,” “second,” and “third” may be used to describe various elements, but it should be understood that these elements should not be limited by these terms. These terms are primarily used to distinguish one element from another, or one signal from another. Furthermore, the term “or” in this specification should be understood to include any one or more of the items listed in relation to it, depending on the actual situation.

[0012] Embodiments of the present invention provide a control device capable of supporting video output. The control device described herein can be combined with a handheld device, and the user can perform various input operations on the handheld device via the control device. For example, when the control device is connected to the handheld device via a transmission interface, the control device can transmit input signals from the user's operation to the handheld device via the transmission interface. On the other hand, the control device can be connected to external devices with different functions to expand its applications to various uses. For example, the control device can output the display screen of the handheld device to an external device for display, or it can acquire input power to charge the handheld device, thus improving the operability of the control device.

[0013] [Control device control example] The explanation will be given with reference to Figures 1 and 2. Figure 1 is a schematic diagram of the structure of a control device capable of supporting video output according to an embodiment of the present invention. Figure 2 is a schematic diagram of the connection between a control device capable of supporting video output and a display device according to an embodiment of the present invention. The control device C1 capable of supporting video output according to this embodiment can perform input control to a handheld device via control interfaces U1 and U2. In this way, the user can perform various controls on the execution software in the handheld device 20 by operating the control interfaces U1 and U2. Here, the control device C1 is connected, for example, between two handles H1 and H2 for operation by the user with the left and right hands via a bridge mechanism B1. Also, when the handheld device 20 is used in combination with the control device C1, the handheld device 20 may be positioned between the two handles H1 and H2. On the other hand, in other embodiments, the combined position of the handheld device 20 and the control device C1 may be any other position that can be operated according to the actual usage requirements.

[0014] In one embodiment, the bridge mechanism B1 may have various different embodiments, such as being retractable, foldable, or detachable. This allows for a unified connection between two handles H1 and H2 via the bridge mechanism B1. Furthermore, the bridge mechanism B1 can also provide a signal transmission channel between the two handles H1 and H2, so that input signals generated by the user's operation of the control interfaces U1 and U2 of either handle can be smoothly transmitted to the handheld device.

[0015] In one embodiment, the transmission interface provided by the control device C1 includes at least a first transmission port P1 and a second transmission port P2. A handheld device 20 may be connected to the first transmission port P1, and an external device may be connected to the second transmission port P2. Furthermore, the control device C1 can relatively determine the function of the second transmission port P2 depending on the different objects connected to the second transmission port P2. Here, the first transmission port P1 is determined to be used in connection with the handheld device 20, while the external device connected to the second transmission port P2 can be selected from different types of external devices depending on different functional operating requirements.

[0016] For the sake of explanation, the first transmission port P1 and the second transmission port P2 are commonly provided on one of the handles H1, but in other embodiments, the first transmission port P1 and the second transmission port P2 may be provided on different handles, such as handle H2. For example, the first transmission port P1 in Figure 1 may be located on the side of handle H1 adjacent to the bridge mechanism B1, and the second transmission port P2 may be flexibly located on either side of handle H1 depending on the connection requirements of external devices.

[0017] In one embodiment, the handle H1 is provided with a control circuit 1. The control circuit 1 is connected to the first transmission port P1 and the second transmission port P2 respectively, and can control the transmission direction of data and power between the first transmission port P1 and the second transmission port P2. For example, the control circuit 1 can transmit an input signal generated by the control interfaces U1 and U2 of the control device C1 to the handheld device 20 via the first transmission port P1. The control circuit 1 determines whether an external device connected to the second transmission port P2 is a power supplying device or a power receiving device by recognizing the external device. In other embodiments, only one of the control interface U1 or the control interface U2 may be provided, and may be arranged on one of the handle H1 or the handle H2.

[0018] In one embodiment, when the external device is a power receiving device, the control circuit 1 can acquire the display signal and the first input power of the handheld device 20 via the first transmission port P1, and transmit the display signal and the first input power to the external device via the second transmission port P2. In addition, when the external device is a power supplying device, the control circuit 1 can acquire the second input power provided by the external device via the second transmission port P2, and transmit the second input power to the handheld device 20 via the first transmission port P1.

[0019] In one embodiment, when the power supplying device is, for example, a charging device, the charging device can charge the handheld device 20 via the control device C1. When the power receiving device is, for example, a display device, the display device can receive and display the display signal of the handheld device 20 via the control device C1, and further, the power used for the operation of the display device may be supplied by the handheld device 20.

[0020] In one embodiment, the handheld device 20 is, for example, a mobile phone, a tablet computer, a handheld computer, a portable game console, a navigation device, or a video playback device. The first transmission port P1 and the second transmission port P2 may be connectors, and the connector may be configured as a male connector or a female connector according to usage requirements. The connector may comply with USB transmission specifications. Further, the connector is, for example, a USB Type-C transmission port interface, or a connector capable of transmitting video signals and power signals.

[0021] Description will be given with reference to FIG. 2. An external device and the handheld device 20 are respectively connected to the control device C1 shown in FIG. 2. Here, as the external device, a display device (displayer) 21 can be mentioned.

[0022] When the control device C1 is used in combination with the handheld device 20, for example, the handheld device 20 is connected to the first transmission port P1 of the control device C1, and the display device 21 is connected to the second transmission port P2 of the control device C1. At this time, the control circuit 1 in the control device C1 may determine, via the second transmission port P2, that the currently connected external device belongs to the display device 21, and control the handheld device 20 to output a display signal to the display device 21 based on this determination result. For example, the display signal of the handheld device 20 may be transmitted to the display device 21 via the first transmission port P1 and the second transmission port P2 for display. At the same time, the first input power of the handheld device 20 also supplies power to the display device 21 via the first transmission port P1 and the second transmission port P2. That is, at this time, the display device 21 can operate by acquiring the first input power provided from the handheld device 20, and can also display the display signal provided from the handheld device 20.

[0023] In one embodiment, the display device 21 is, for example, VR glasses or a flat-panel display. When a user operates and uses the handheld device 20 via the control device C1, the display screen of the handheld device 20 can be transmitted to and displayed on the display device 21, thereby improving ease of operation.

[0024] The explanation will be given with reference to Figure 3. Figure 3 is a schematic diagram of the connection between a control device and a charging device that can support video output according to an embodiment of the present invention. An external device and a handheld device 20 are connected to the control device C1 shown in Figure 3. Here, the external device is a charging device 22.

[0025] When the control device C1 is used in combination with the handheld device 20, for example, the handheld device 20 is connected to the first transmission port P1 of the control device C1, and the charging device 22 is connected to the second transmission port P2 of the control device C1. At this time, the control circuit 1 in the control device C1 may determine via the second transmission port P2 that the currently connected external device belongs to the charging device 22, and based on this determination result, control the charging device 22 to charge the handheld device 20.

[0026] For example, the charging signal from the charging device 22 may charge the handheld device 20 via the second transmission port P2 and the first transmission port P1. The charging signal can become the second input power. In this case, the external device is no longer the display device 21 shown in Figure 2, so the display signal from the handheld device 20 is not transmitted to the external device for display purposes via the first transmission port P1 and the second transmission port P2, as shown in Figure 2. Also, in this case, the first input power from the handheld device 20 is not input to the control device C1.

[0027] In other words, under the structure shown in Figure 3, the control device C1 can acquire a second input power supplied from the charging device 22, which can then charge the handheld device 20, thus extending the usage time of the handheld device 20.

[0028] In one embodiment, the charging device 22 is, for example, a charger or a mobile battery.

[0029] The explanation will be given with reference to Figure 4. Figure 4 is a schematic diagram of the connection between a control device capable of supporting video output according to an embodiment of the present invention and a plurality of external devices. The control device shown in Figure 4 is connected to a plurality of external devices and a handheld device 20, respectively. Here, the plurality of external devices include a display device 21 and a charging device 22.

[0030] When the control device C2 is used in combination with the handheld device 20, for example, the handheld device 20 is connected to the first transmission port P1 of the control device C2, the display device 21 is connected to the second transmission port P2 of the control device C2, and the charging device 22 is connected to the third transmission port P3 of the control device C2. In this case, the control device C2 is configured to be used with the display device 21 connected to the second transmission port P2 and the charging device 22 connected to the third transmission port P3. Compared with the control device C1 in Figure 3, the control device C2 shown in Figure 4 is provided with an additional third transmission port P3. Here, multiple external devices can be connected to the control device C2 via the second transmission port P2 and the third transmission port P3.

[0031] For example, if the control circuit 1 of the control device C2 determines that the first external device currently connected via the second transmission port P2 belongs to the display device 21, and the second external device currently connected to the third transmission port P3 belongs to the charging device 22, the control circuit 1 of the control device C2 may then control the charging device 22 to charge the handheld device 20 and supply power to the display device 21. For example, the charging signal from the charging device 22 can charge the handheld device 20 via the third transmission port P3 and the first transmission port P1, and the charging signal from the charging device 22 can also supply power to the display device 21 via the third transmission port P3 and the second transmission port P2. Furthermore, the display signal from the handheld device 20 can be transmitted to the display device 21 via the first transmission port P1 and the second transmission port P2 and displayed.

[0032] In one embodiment, under the structure shown in Figure 4, the external objects connected to the second transmission port P2 and the third transmission port P3 are predetermined. Therefore, if the object connected to the second transmission port P2 is not the display device 21, the second transmission port P2 will not function. Similarly, if the object connected to the third transmission port P3 is not the charging device 22, the third transmission port P3 will also not function. On the other hand, if the display device 21 is connected only to the second transmission port P2 of the two transmission ports P2 and the third transmission port P3, refer to Figure 2 for the control method of the control device C2 in this case. Furthermore, if the charging device 22 is connected only to the third transmission port P3 of the two transmission ports P2 and the third transmission port P3, refer to Figure 3 for the control method of the control device C2 in this case.

[0033] Therefore, with the structure shown in Figure 4, the control device C2 can output the display screen of the handheld device 20 to the display device 21 for display, and the handheld device 20 does not need to supply power to the display device 21. On the other hand, the charging device 22 supplies power to the display device 21, but at the same time, the charging device 22 can also charge the handheld device 20. In this way, the user can view the display device 21 for a long time with this connection structure, and the effect of operating the handheld device 20 for a long time is also ensured.

[0034] The explanation will be given with reference to Figure 5. Figure 5 is a schematic diagram of the connection between a control device capable of supporting video output according to an embodiment of the present invention and a plurality of external devices. The control device shown in Figure 5 is connected to a plurality of external devices and a handheld device 20, respectively. Here, the external devices include a display device 21 and a charging device 22.

[0035] When the control device C3 is used in combination with the handheld device 20, for example, the handheld device 20 is connected to the first transmission port P1 of the control device C3. In this case, both the second transmission port P2 and the third transmission port P3 of the control device C3 can be flexibly selected to be used as either a display device 21 or a charging device 22, depending on the usage requirements. For example, as shown in Figure 5, the charging device 22 is connected to the second transmission port P2 of the control device C3, and the display device 21 is connected to the third transmission port P3 of the control device C3.

[0036] Furthermore, if the control circuit 1 of the control device C3 determines that the first external device currently connected via the second transmission port P2 is the charging device 22, and the second external device currently connected via the third transmission port P3 is the display device 21, the control circuit 1 of the control device C3 may control the charging device 22 to charge the handheld device 20 and supply power to the display device 21. For example, the charging signal (second input power) of the charging device 22 can charge the handheld device 20 via the second transmission port P2 and the first transmission port P1, and the charging signal of the charging device 22 can supply power to the display device 21 via the second transmission port P2 and the third transmission port P3. Furthermore, the display signal of the handheld device 20 can be displayed on the display device 21 via the first transmission port P1 and the third transmission port P3. Similarly, if the control circuit 1 of the control device C3 determines that the connection method of the second transmission port P2 and the third transmission port P3 is as shown in Figure 4, it can perform relative control by referring to the method in Figure 4 described above.

[0037] It is noteworthy that the control device C3 shown in Figure 5 can determine the function of the transmission port based on which of the second transmission port P2 and the third transmission port P3 is connected first, that is, based on the object that is connected to the transmission port first. For example, if the control circuit 1 determines that the first external device connected first to the second transmission port P2 is a charging device 22, it can set the second external device connected later to the third transmission port P3 to be used as a display device 21. Alternatively, if the control circuit 1 determines that the first external device connected first to the third transmission port P3 is a charging device 22, it can set the second external device connected later to the second transmission port P2 to be used as a display device 21.

[0038] It is noteworthy that, in the structure shown in Figure 5, the control device C3 can automatically recognize the connection targets for the second transmission port P2 and the third transmission port P3. In other words, the connection targets for the second transmission port P2 and the third transmission port P3 are not predetermined, allowing the user to flexibly connect and use different external devices on the control device C3, thereby improving ease of operation.

[0039] In one embodiment, the control device C3 in Figure 5 may be further provided with a corresponding instruction interface for guiding the user to know the current connected devices (e.g., the display device 21 or the charging device 22) of the second transmission port P2 and the third transmission port P3.

[0040] For example, as shown in Figure 5, the instruction interface may have a first indicator L1 and a second indicator L2 on one side adjacent to the second transmission port P2 and the third transmission port P3, respectively. If the first external device connected to the second transmission port P2 is a charging device 22, the first indicator L1 adjacent to the second transmission port P2 displays the corresponding optical signal of the charging device 22 (e.g., the first instruction signal), and the second indicator L2 adjacent to the third transmission port P3 displays the corresponding optical signal of the display device 21 (e.g., the second instruction signal). If the first external device connected to the third transmission port P3 is a charging device 22, the second indicator L2 adjacent to the third transmission port P3 displays the corresponding optical signal of the charging device 22 (e.g., the first instruction signal), and the first indicator L1 adjacent to the second transmission port P2 displays the corresponding optical signal of the display device 21 (e.g., the second instruction signal). This allows users to clearly identify the connected devices to the second transmission port P2 and the third transmission port P3 through the display of optical signals.

[0041] In one embodiment, the first indicator L1 is a first light-emitting element, the second indicator L2 is a second light-emitting element, the first instruction signal is a first optical signal, and the second instruction signal is a second optical signal. The first optical signal and the second optical signal display different optical signals. The first light-emitting element is positioned adjacent to the second transmission port P2, and the second light-emitting element is positioned adjacent to the third transmission port P3. The first and second light-emitting elements are, for example, light-emitting diodes (LEDs).

[0042] The explanation will be given with reference to Figure 6. Figure 6 is a schematic diagram of the connection between a control device and a charging device capable of supporting video output according to an embodiment of the present invention. The control device C4 shown in Figure 6 is connected to the charging device and the handheld device 20, respectively. Here, the charging device is a mobile battery PB.

[0043] As shown in Figure 6, the connection point for the mobile battery PB is the bridge mechanism B2 between the two handles H1 and H2. That is, the third transmission port P3 may be placed near the bridge mechanism B2. This allows the mobile battery PB to be mounted on the bridge mechanism B2 and further connected to the third transmission port P3. Therefore, if the handheld device 20 is connected to the first transmission port P1 of the control device C4, the display device 21 is connected to the second transmission port P2, and the charging device is connected to the third transmission port P3, and the display device 21 is VR glasses and the charging device is the mobile battery PB, then the mobile battery PB is mounted on one side of the bridge mechanism B2 and the handheld device 20 is located on the opposite side of the bridge mechanism B2. That is, the handheld device 20 and the mobile battery PB are positioned on the front and back of the bridge mechanism B2, respectively. Combined with the user directly wearing the VR glasses, this allows the user to smoothly operate and use the control device C3 while on the move.

[0044] [Example of a control device circuit] The explanation will be given with reference to Figure 7. Figure 7 is a circuit block diagram of a control device according to an embodiment of the present invention. The control circuit 1 of the control device C1 shown in Figure 7 includes, but is not limited to, a transmission controller 10, a power transmission circuit 11, a data transmission circuit 12, a peripheral controller 13, and a peripheral input device 14. Here, the transmission controller 10 is connected to a first transmission port P1, a second transmission port P2, a power transmission circuit 11, a data transmission circuit 12, and a peripheral controller 13. The power transmission circuit 11 is connected to the first transmission port P1 and the second transmission port P2. The peripheral controller 13 is connected to the first transmission port P1 and the peripheral input device 14. The data transmission circuit 12 is connected to the first transmission port P1 and the second transmission port P2.

[0045] In one embodiment, when a handheld device 20 is connected to the first transmission port P1, the transmission controller 10 and the peripheral controller 13 communicate with the handheld device 20 via the first transmission port P1, and then the transmission controller 10 and the peripheral controller 13 can obtain power supplied from the handheld device 20 via the power transmission circuit 11. In this way, the control device C1 can operate normally. For example, the peripheral controller 13 is responsible for various input operations of the peripheral input device 14 and transmits the input signals generated by the peripheral input device 14 to the handheld device 20 via the first transmission port P1 to achieve the operational effect of controlling the handheld device 20. Here, the peripheral input device 14 is used as the control interfaces U1 and U2 of the control device C1. The peripheral input device 14 may be, for example, various combinations of buttons and joysticks. Furthermore, the buttons may be digital buttons or analog buttons.

[0046] For example, the transmission controller 10 communicates with the handheld device 20 or an external device in the following manner. The transmission controller 10 has a first recognition pin and a second recognition pin, the first recognition pin is connected to a first transmission port P1, and the second recognition pin is connected to a second transmission port P2. Therefore, the transmission controller 10 grasps the connection status of the handheld device 20 via the first recognition pin, recognizes the external device via the second recognition pin, and further controls the power transmission circuit 11 to transmit either the first input power or the second input power according to the recognition results of the first and second recognition pins.

[0047] Specifically, in this case, the transmission controller 10 is responsible for transmitting data or power between the first transmission port P1 and the second transmission port P2. For example, as shown in Figure 2, if the control device C1 is connected to the handheld device 20 via the first transmission port P1 and the external device connected to the second transmission port P2 is a display device 21, the second recognition pin of the transmission controller 10 communicates with the external device via the second transmission port P2 and then determines that this external device is a display device 21. Subsequently, the first recognition pin of the transmission controller 10 can communicate with the handheld device 20 connected to the first transmission port P1 to inform the handheld device 20 that it needs to continue supplying power to the control device C1. In other words, the first input power of the handheld device 20 is continuously input to the power transmission circuit 11 via the first transmission port P1, and the transmission controller 10 controls the power transmission circuit 11 and transmits this first input power to the peripheral controller 13 and the transmission controller 10 to supply power. In addition, the power transmission circuit 11 simultaneously transmits this first input power to the second transmission port P2, so that the display device 21 currently connected to the second transmission port P2 can receive the supply of the first input power and operate normally.

[0048] Furthermore, the transmission controller 10 notifies the handheld device 20 connected to the first transmission port P1 via the first recognition pin that the display device 21 is currently connected to the second transmission port P2. Accordingly, the transmission controller 10 further acquires the display signal output by the handheld device 20 via the first transmission port P1 and controls this display signal to transmit it to the display device 21 connected to the second transmission port P2 via the data transmission circuit 12. As a result, the display device 21 can start playback upon receiving this display signal.

[0049] On the other hand, as shown in Figure 3, in the control device C1, if a handheld device 20 is connected to the first transmission port P1 and an external device connected to the second transmission port P2 is a charging device 22, the second recognition pin of the transmission controller 10 communicates with the external device via the second transmission port P2 and then determines that this external device is a charging device 22. Subsequently, the first recognition pin of the transmission controller 10 can communicate with the handheld device 20 connected to the first transmission port P1 to notify the handheld device 20 that it no longer needs to supply power to the control device C1. That is, at this time, the first input power of the handheld device 20 no longer needs to be continuously input to the power transmission circuit 11 via the first transmission port P1 and is changed to the second input power provided by the charging device 22. Furthermore, the transmission controller 10 controls the power transmission circuit 11 to supply this second input power to the peripheral controller 13 and the transmission controller 10, and simultaneously transmits this second input power to the first transmission port P1, so that the handheld device 20 currently connected to the first transmission port P1 can acquire the second input power and be charged.

[0050] Furthermore, the transmission controller 10 notifies the handheld device 20 connected to the first transmission port P1 via the first recognition pin that the charging device 22 is currently connected to the second transmission port P2. Therefore, it is no longer necessary to transmit the display signal from the handheld device 20 to the control device C1. That is, at this time, the transmission controller 10 controls the data transmission circuit 12 to stop data transmission to the charging device 22 connected to the second transmission port P2.

[0051] Specifically, the transmission controller 10 in Figure 7 communicates with externally connected devices via the first transmission port P1 and the second transmission port P2, respectively. Based on the communication results, it controls the power transmission circuit 11 to perform the corresponding power supply transmission and the data transmission circuit 12 to perform the corresponding data transmission. Here, the power transmission circuit 11 has a bidirectional power transmission function and can, for example, acquire input power from one of the transmission ports, the first transmission port P1 and the second transmission port P2, and output this input power to the other transmission port. The input power acquired by the power transmission circuit 11 is also used simultaneously as operating power for the internal related elements of the control device C1.

[0052] The explanation will be given with reference to Figure 8. Figure 8 is a circuit block diagram of a control device according to an embodiment of the present invention. Compared with Figure 7, the structure of the control device shown in Figure 8 has an additional auxiliary controller 15. Only the differences will be explained here; for explanations of elements with the same reference numerals, please refer to Figure 7. The auxiliary controller 15 in the control circuit 1a shown in Figure 8 is connected between the first transmission port P1, the power transmission circuit 11, and the peripheral controller 13.

[0053] Here, the auxiliary controller 15 may obtain power via the power transmission circuit 11. This power supply may be a first input power provided from a handheld device 20 externally connected to the first transmission port P1, or a second input power provided from a charging device 22 externally connected to the second transmission port P2.

[0054] In one embodiment, the auxiliary controller 15 may process the audio data within the display signal of the handheld device 20 individually and then output the audio signal to the data transmission circuit 12. In this case, the data transmission circuit 12 may output the video data (acquirable from the first transmission port P1) and audio data (acquirable from the auxiliary controller 15) within the display signal of the handheld device 20 to the display device 21 connected to the second transmission port P2, respectively.

[0055] It should be noted that the display device 21 connected to the second transmission port P2 in Figure 8 supports the independent reception of video data and audio data. This differs from the display device 21 connected to the second transmission port P2 in Figure 7, which supports a single video-audio transmission interface capable of simultaneously receiving video data and audio data. This single video-audio transmission interface is, for example, a DP (Display Port) transmission interface. That is, the auxiliary controller 15 of the control device C1 shown in Figure 8 may individually extract and process the audio data within the DP display signal provided by the handheld device 20 at the first transmission port P1, and output it to the display device 21 connected to the second transmission port P2 via the data transmission circuit 12. As a result, the display device 21, which can use video data and independent audio data, can still play back the video data and independent audio data within the DP display signal normally even after receiving them.

[0056] The explanation will be given with reference to Figure 9. Figure 9 is a circuit block diagram of a control device according to an embodiment of the present invention. Compared with Figure 8, the structure of the control device C2 shown in Figure 9 has a third transmission port P3 added. Only the differences will be explained here; for explanations of elements with the same reference numerals, please refer to Figures 7 and 8. The third transmission port P3 shown in Figure 9 is connected to the data transmission circuit 12 and the power transmission circuit 11.

[0057] The first external device connected to the second transmission port P2 and the second external device connected to the third transmission port P3, as shown in Figure 9, are predetermined. In one embodiment, the control circuit 1b controls the system so that the charging device 22 is determined to be used as the first external device and the display device 21 is determined to be used as the second external device.

[0058] For example, if the handheld device 20 is connected only to the first transmission port P1 in the control device C2, the transmission controller 10 communicates with the handheld device 20 via the first transmission port P1, and then controls the power transmission circuit 11 to receive the first input power provided by the handheld device 20 via the first transmission port P1. This first input power may also be further distributed to the transmission controller 10, the auxiliary controller 15, and the peripheral controller 13 for use.

[0059] Next, if the display device 21 is first connected to the third transmission port P3 of the control device C2, and the charging device 22 is later connected to the second transmission port P2, the transmission controller 10 communicates with the handheld device 20 via the first transmission port P1 and with the charging device 22 via the second transmission port P2. After this, the transmission controller 10 controls the power transmission circuit 11 and receives the second input power provided by the charging device 22 via the second transmission port P2. This second input power may also be distributed and used by the transmission controller 10, the auxiliary controller 15, and the peripheral controller 13. Furthermore, the second input power may be used to charge the handheld device 20 via the first transmission port P1 and to supply power to the display device 21 via the third transmission port P3.

[0060] Furthermore, the transmission controller 10 controls the data transmission circuit 12 to acquire the display signal from the handheld device 20. The data transmission circuit 12 also outputs the display signal from the handheld device 20 to the display device 21 via the third transmission port P3 for playback. Using the structure shown in Figure 9 as an example, if the display signal from the handheld device 20 is, for example, a DP display signal, when this DP display signal is input into the control device C2 via the first transmission port P1, the DP display signal is split into two signals, video data and audio data, and transmitted separately. Here, the video data in the DP display signal is output directly to the data transmission circuit 12, while the audio data in the DP display signal is transmitted to the auxiliary controller 15, where the auxiliary controller 15 processes this audio data to conform to the audio playback format of the display device 21. Finally, the data transmission circuit 12 transmits the video data and audio data in this DP display signal to the display device 21 for playback.

[0061] In one embodiment, if a handheld device 20 is connected to the control device C2 in Figure 9, and then a charging device 22 is connected to the second transmission port P2, followed by the display device 21 being connected to the third transmission port P3, the transmission controller 10 may, upon detecting this situation, control the system to stop the function of the display device 21.

[0062] In one embodiment, if a handheld device 20 is connected to the control device C2 in Figure 9, and the display device 21 is connected only to the third transmission port P3, the transmission controller 10 may, upon detecting this situation, control the system to stop the function of the display device 21.

[0063] The explanation will be given with reference to Figure 10. Figure 10 is a circuit block diagram of a control device according to an embodiment of the present invention. Compared with Figure 9, the structure of the control device C3 shown in Figure 10 includes the addition of a detection controller 16 and another data transmission circuit (for example, a second data transmission circuit 122). Only the differences will be explained here; for explanations of elements with the same reference numerals, please refer to the embodiments described above.

[0064] It should be noted that the first external device connected to the second transmission port P2 and the second external device connected to the third transmission port P3 shown in Figure 10 are not predetermined. In one embodiment, the control device C2 may use the charging device 22 as the first external device and the display device 21 as the second external device, based on the control of the control circuit 1c. Alternatively, the display device 21 may be used as the first external device and the charging device 22 as the second external device. Or, either the first external device or the second external device may be a combination of a charging device (or display device) and an input device (e.g., a mouse or keyboard).

[0065] The detection controller 16 in Figure 10 is connected to the transmission controller 10 and the third transmission port P3. The first data transmission circuit 121 is connected to the first transmission port P1, the auxiliary controller 15, and the second transmission port P2, and the second data transmission circuit 122 is connected to the first transmission port P1, the auxiliary controller 15, and the third transmission port P3. The third recognition pin of the transmission controller 10 may also be connected to the detection controller 16, and the transmission controller 10 communicates with an external device connected to the third transmission port P3 via the third recognition pin. The third recognition pin of the transmission controller 10 recognizes the second external device connected to the third transmission port P3 via the detection controller 16. In other embodiments, the third recognition pin of the transmission controller 10 may be directly connected to the third transmission port P3 to recognize the second external device.

[0066] In one embodiment, after a handheld device 20 is connected to the first transmission port P1 of the control device C3 in Figure 10, the first external device connected to the second transmission port P2 is a charging device 22, and the second external device connected to the third transmission port P3 is a display device 21. In this case, the transmission controller 10 can determine the current connection status of the control device C3 based on the communication results of the first, second, and third recognition pins. As a result, the transmission controller 10 controls the power transmission circuit 11 to obtain the second input power provided from the charging device 22 via the second transmission port P2. The power transmission circuit 11 may be further distributed and used by the transmission controller 10, the auxiliary controller 15, and the peripheral controller 13. The second input power may also be used to charge the handheld device 20 via the first transmission port P1 and to supply power to the display device 21 via the third transmission port P3. Simultaneously, the transmission controller 10 controls the second data transmission circuit 122 to acquire the display signal from the handheld device 20, and the second data transmission circuit 122 outputs the display signal from the handheld device 20 to the display device via the third transmission port P3 for playback.

[0067] In one embodiment, after a handheld device 20 is connected to the first transmission port P1 of the control device C3 in Figure 10, the first external device connected to the second transmission port P2 is a display device 21, and the second external device connected to the third transmission port P3 is a charging device 22. In this case, the transmission controller 10 can determine the current connection status of the control device C3 based on the communication results of the first, second, and third recognition pins. As a result, the transmission controller 10 controls the power transmission circuit 11 to obtain the second input power provided from the charging device 22 via the third transmission port P3. The power transmission circuit 11 may be further distributed and used by the transmission controller 10, the auxiliary controller 15, and the peripheral controller 13. The second input power may also be used to charge the handheld device 20 via the first transmission port P1 and to supply power to the display device 21 via the second transmission port P2. Simultaneously, the transmission controller 10 controls the first data transmission circuit 121 to acquire the display signal from the handheld device 20, and the first data transmission circuit 121 outputs the display signal from the handheld device 20 to the display device 21 via the second transmission port P2 for playback.

[0068] The explanation will be given with reference to Figure 11. Figure 11 is a circuit block diagram of a control device according to an embodiment of the present invention. Compared with Figure 9, the structure of the control device C3 shown in Figure 11 has an added instruction interface LD. Only the differences will be explained here; for explanations of elements with the same reference numerals, please refer to the embodiments described above.

[0069] In one embodiment, a peripheral controller 13 is connected to the instruction interface LD of the control circuit 1d, and a transmission controller 10 is connected to the peripheral controller 13. The peripheral controller 13 controls the instruction interface LD relative to the second and third recognition pins of the transmission controller 10.

[0070] In one embodiment, the instruction interface LD includes, for example, a first indicator L1 and a second indicator L2. When the first external device is a charging device 22 and the second external device is a display device 21, the peripheral controller 13 controls the first indicator L1 to display a first instruction signal and the second indicator L2 to display a second instruction signal. When the first external device is a display device 21 and the second external device is a charging device 22, the peripheral controller 13 controls the first indicator L1 to display a second instruction signal and the second indicator L2 to display a first instruction signal.

[0071] In one embodiment, the auxiliary controller 15 shown in Figures 8 to 11 above is suitable when the display device 21 connected to the control device C1 uses the audio data within the DP display signal independently. On the other hand, when the display device 21 connected to the control device C1 directly supports the DP display signal (i.e., when the audio data within the DP display signal is not used independently), the control device C1 does not need to use the auxiliary controller 15, and the display signal from the first transmission port P1 is transmitted directly to the data transmission circuit 12.

[0072] In one embodiment, the first transmission port P1, the second transmission port P2, and the third transmission port P3 are connectors compliant with the USB (Universal Serial Bus) Type-C standard, and the first, second, and third recognition pins of the transmission controller 10 communicate with the objects connected to the first transmission port P1, the second transmission port P2, and the third transmission port P3 via their respective channel (Configuration Channel, CC) pins, and recognize the connected objects based on the CC channel signals of these channel pins. Furthermore, the first transmission port P1, the second transmission port P2, and the third transmission port P3 may be USB Type-C transmission port interfaces that support DP (Display Port) video functionality. As a result, the display signal from the handheld device 20 is output to another display device via the control device C1, and this display device plays the video and audio within this display signal.

[0073] In one embodiment, the control circuit 1 may be, for example, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a system-on-a-chip (SoC), or any combination thereof. Furthermore, the above-described functions and processes may be realized by combining them with other relevant circuit elements and firmware.

[0074] In one embodiment, the transmission controller 10 may be a USB-PD controller, the peripheral controller 13 may be a USB controller, and the auxiliary controller 15 may be a USB hub. <Beneficial effects of the examples>

[0075] The control device according to the present invention, which supports video output, can display the display screen of a handheld device on an external display device connected to the control device when used in combination with a handheld device, thereby improving the convenience of using the control device.
