Description

[Technical Field]

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

[0002] Handheld devices are characterized by their portability. However, some users find that the control functions of handheld devices do not meet their needs. Therefore, control devices that can be combined with handheld devices are available on the market. These control devices have a mechanical design that allows them to be easily carried even when combined with a handheld device. Summary of the Invention [Problem to be solved by the invention]

[0003] Therefore, when a user (e.g., a game player) who values ​​the convenience of control combines the above-mentioned control device with a handheld device, the user can perform input control corresponding to the handheld device through the control interface provided by the control device itself. However, since the display screen of the handheld device is limited by the body size, the visual effect of the handheld device is limited during overall operation.

[0004] A technical problem to be solved by the present invention is to provide a control device capable of supporting video output in consideration of the shortcomings of the prior art. [Means for solving the problem]

[0005] An embodiment of the present invention provides a control device capable of supporting video output, including 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 receives first input power 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 to power the display device, receives a display signal from the handheld device via the first transmission port, and 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 the first input power, receives second input power from the charging device via the second transmission port, and controls the second input power to be output to the first transmission port to power the handheld device.

[0006] An embodiment of the present invention provides a control device capable of supporting video output, including a transmission interface and a control circuit. The transmission interface has a first transmission port, a second transmission port, and a third transmission port. The control circuit receives a first input power from the handheld device via the first transmission port when the handheld device is connected to 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. When 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 the first input power, receives a second input power from the charging device via the second transmission port, and controls the second input power to be output to the first transmission port to power the handheld device and to be output to the third transmission port to power the display device. The control circuit receives a display signal from the handheld device via the first transmission port and controls the display signal to be output to the display device via the third transmission port for display.

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

[0010] Hereinafter, embodiments of the present invention will be described 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 content. The present invention can be implemented or applied through other different specific embodiments, and various detailed descriptions herein can be modified and changed in various ways based on different perspectives and applications without departing from the spirit of the present invention. It should be noted in advance that the drawings of the present invention are merely schematic and are not drawn to actual scale. The technical content of the present invention will be described in more detail using the following embodiments, but the disclosed content is not intended to limit the protection scope of the present invention.

[0011] In the 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. Also, the term "or" in this specification should be understood to include any one or more combinations of the associated listed items, depending on the actual circumstances.

[0012] An embodiment of the present invention provides a control device capable of supporting video output. The control device described herein can be combined with a handheld device, allowing a user to perform various input operations on the handheld device through the control device. For example, when the control device is connected to the handheld device via a transmission interface, the control device can transmit an input signal from a user's operation to the handheld device via the transmission interface. Meanwhile, the control device can be connected to external devices having different functions to expand its applications. For example, the control device can output the display screen of the handheld device to the external device for display, or obtain input power to charge the handheld device, thereby improving the convenience of using the control device.

[0013] [Control example of control device] The following description will be given with reference to FIGS. 1 and 2. FIG. 1 is a structural diagram of a control device capable of supporting video output according to an embodiment of the present invention. FIG. 2 is a schematic diagram illustrating the connection between a control device capable of supporting video output according to an embodiment of the present invention and a display device. The control device C1 capable of supporting video output according to this embodiment can perform input control for the handheld device 20 via the control interfaces U1 and U2. In this way, a user can perform various controls on software running on the handheld device 20 by operating the control interfaces U1 and U2. Here, the control device C1 is connected, for example, via a bridge mechanism B1 between two handles H1 and H2 for the user to operate with their left and right hands. Furthermore, 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. Meanwhile, in other embodiments, the combination position of the handheld device 20 and the control device C1 may be any other operable position depending on actual usage requirements.

[0014] In some embodiments, the bridge mechanism B1 may have various different embodiments, such as telescopic, foldable, or detachable, so that the two handles H1 and H2 can be integrally connected 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 a user operating 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. The 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 determine the function of the second transmission port P2 relatively according to different objects connected to the second transmission port P2. Here, the first transmission port P1 is determined to be connected to the handheld device 20, while the external device connected to the second transmission port P2 can be selected from different types of external devices according to different functional operation requirements.

[0016] For convenience of explanation, the first transmission port P1 and the second transmission port P2 are shown here as being commonly provided on one handle 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 FIG. 1 may be located on the side of the handle H1 adjacent to the bridge mechanism B1, and the second transmission port P2 may be flexibly located on either side of the handle H1 depending on the connection requirements of external devices.

[0017] In one embodiment, a control circuit 1 is provided in the handle H1. 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 input signals 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 recognizes the external device connected to the second transmission port P2 and determines whether the external device is a power supply device or a power receiving device. In other embodiments, only one of the control interface U1 or the control interface U2 may be provided and located on either the handle H1 or the handle H2.

[0018] In an embodiment, when the external device is a power receiving device, the control circuit 1 can receive an indication signal and a first input power of the handheld device 20 through the first transmission port P1 and transmit the indication signal and the first input power to the external device through the second transmission port P2. When the external device is a power supplying device, the control circuit 1 can receive a second input power provided by the external device through the second transmission port P2 and transmit the second input power to the handheld device 20 through the first transmission port P1.

[0019] In an embodiment, when the power supply 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 a display signal from the handheld device 20 via the control device C1, and further, the power used to operate the display device may be supplied by the handheld device 20.

[0020] In some embodiments, the handheld device 20 may be, 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, which may be configured as male or female connectors depending on usage requirements. The connectors may comply with the USB transmission specification. Furthermore, the connectors may be, for example, a USB Type-C transmission port interface or a connector capable of transmitting video signals and power signals.

[0021] The following description will be made with reference to Fig. 2. An external device and a handheld device 20 are connected to a control device C1 shown in Fig. 2. Here, the external device may be a display device 21.

[0022] When the control device C1 is used in combination with a 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 based on this determination, control the handheld device 20 to output a display signal to the display device 21. 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 obtaining 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 display. When a user operates and uses the handheld device 20 through 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 the convenience of operation.

[0024] The following description will be given with reference to Fig. 3. Fig. 3 is a schematic diagram showing the connection between a control device capable of supporting video output and a charging device 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 Fig. 3. Here, the external device may be a charging device 22.

[0025] When the control device C1 is used in combination with a 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 of 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 may be the second input power. At this time, the external device is no longer the display device 21 shown in FIG. 2, so the display signal of the handheld device 20 is not transmitted to the external device for display via the first transmission port P1 and the second transmission port P2 as shown in FIG. 2. At this time, the first input power of the handheld device 20 is also not input to the control device C1.

[0027] That is, under the structure of FIG. 3, the control device C1 can obtain the second input power provided by the charging device 22, and the second input power can charge the handheld device 20, thus extending the usage time of the handheld device 20.

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

[0029] The following description will be given with reference to Fig. 4. Fig. 4 is a schematic diagram showing connections between a control device capable of supporting video output according to an embodiment of the present invention and a plurality of external devices. A plurality of external devices and a handheld device 20 are respectively connected to the control device shown in Fig. 4. 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 a handheld device 20, for example, the handheld device 20 is connected to the first transmission port P1 of the control device C2, a display device 21 is connected to the second transmission port P2 of the control device C2, and a charging device 22 is connected to the third transmission port P3 of the control device C2. In this case, it is determined that the control device C2 is 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 of FIG. 3, the control device C2 shown in FIG. 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 control the charging device 22 to charge the handheld device 20 and supply power to the display device 21. For example, a 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, a 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 for display.

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

[0033] 4, the control device C2 can output the display screen of the handheld device 20 to the display device 21 for display, eliminating the need for the handheld device 20 to supply power to the display device 21. Meanwhile, 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, this connection structure allows the user to view the display device 21 for a long time, and also ensures the effect of operating the handheld device 20 for a long time.

[0034] The following description will be given with reference to Fig. 5. Fig. 5 is a schematic diagram showing connections between a control device capable of supporting video output according to an embodiment of the present invention and a plurality of external devices. A plurality of external devices and a handheld device 20 are respectively connected to the control device shown in Fig. 5. 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 a 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, the second transmission port P2 and the third transmission port P3 of the control device C3 can flexibly select whether the connected external device is used as a display device 21 or a charging device 22 according to usage requirements. For example, as shown in FIG. 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 that 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 FIG. 4, it can perform relative control with reference to the method of FIG. 4.

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

[0038] 5, the control device C3 can automatically recognize the connection targets of the second transmission port P2 and the third transmission port P3. That is, the connection targets of the second transmission port P2 and the third transmission port P3 are not predetermined, and users can flexibly connect and use different external devices on the control device C3, which improves operational convenience.

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

[0040] For example, as shown in Fig. 5, the indicating 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 first connected to the second transmission port P2 is a charging device 22, the first indicator L1 adjacent to the second transmission port P2 displays a corresponding light signal (e.g., a first indication signal) of the charging device 22, and the second indicator L2 adjacent to the third transmission port P3 displays a corresponding light signal (e.g., a second indication signal) of the display device 21. If the first external device first connected to the third transmission port P3 is a charging device 22, the second indicator L2 adjacent to the third transmission port P3 displays a corresponding light signal (e.g., a first indication signal) of the charging device 22, and the first indicator L1 adjacent to the second transmission port P2 displays a corresponding light signal (e.g., a second indication signal) of the display device 21. This allows the user to clearly understand the connection targets connected to the second transmission port P2 and the third transmission port P3 through the display of the optical signal.

[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 indication signal is a first optical signal, and the second indication signal is a second optical signal. The first optical signal and the second optical signal indicate different optical signals. The first light-emitting element is disposed adjacent to the second transmission port P2, and the second light-emitting element is disposed adjacent to the third transmission port P3. The first light-emitting element and the second light-emitting element are, for example, light-emitting diodes (LEDs).

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

[0043] As shown in FIG. 6 , the mobile battery PB is connected to the bridge mechanism B2 between the two handles H1 and H2. That is, the third transmission port P3 may be installed near the bridge mechanism B2. This allows the mobile battery PB to be mounted on the bridge mechanism B2 and connected to the third transmission port P3. Therefore, when a handheld device 20 is connected to the first transmission port P1 of the control device C4, a display device 21 is connected to the second transmission port P2, and a 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, the mobile battery PB is mounted on one side of the bridge mechanism B2 and the handheld device 20 is located on the other side of the bridge mechanism B2. That is, the handheld device 20 and the mobile battery PB are located on the front and back of the bridge mechanism B2, respectively. This allows the user to wear the VR glasses directly, allowing the user to hold the control device C3 in their hand and operate and use it smoothly even while on the move.

[0044] [Example of control device circuit] Referring to FIG. 7, FIG. 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 FIG. 7 includes, for example, but 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, the power transmission circuit 11, the data transmission circuit 12, and the 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. The transmission controller 10 and the peripheral controller 13 can then obtain power from the handheld device 20 via the power transmission circuit 11. This allows the control device C1 to function normally. For example, the peripheral controller 13 is responsible for various input operations of the peripheral input device 14 and transmits input signals generated by the peripheral input device 14 to the handheld device 20 via the first transmission port P1 to achieve control effects for the handheld device 20. Here, the peripheral input device 14 serves 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 or analog.

[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, where 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. Thus, the transmission controller 10 determines the connection status of the handheld device 20 through the first recognition pin, recognizes the external device through the second recognition pin, and relatively controls the power transmission circuit 11 to transmit the first input power or the second input power according to the recognition result of the first recognition pin and the second recognition pin.

[0047] Specifically, 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 FIG. 2, when the control device C1 connects to the handheld device 20 through 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 through the second transmission port P2 and identifies the external device as the display device 21. The first recognition pin of the transmission controller 10 then communicates 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. That is, the first input power of the handheld device 20 continues to be input to the power transmission circuit 11 through the first transmission port P1, and the transmission controller 10 controls the power transmission circuit 11 to transmit this first input power to the peripheral controller 13 and the transmission controller 10 to supply power. At the same time, the power transmission circuit 11 also 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 obtain 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 a display device 21 is currently connected to the second transmission port P2. Therefore, the transmission controller 10 further acquires a display signal output by the handheld device 20 via the first transmission port P1 and controls the display signal to be transmitted to the display device 21 connected to the second transmission port P2 via the data transmission circuit 12. This allows the display device 21 to start playback upon receiving the display signal.

[0049] 3, when a handheld device 20 is connected to the first transmission port P1 of the control device C1 and the 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 through the second transmission port P2 and determines that the external device is the charging device 22. The first recognition pin of the transmission controller 10 then communicates 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 through 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 the power transmission circuit 11 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 obtain 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, there is no need to transmit an indication 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] 7 communicates with an externally connected device via the first transmission port P1 and the second transmission port P2, respectively, and controls the power transmission circuit 11 to supply and transmit corresponding power and the data transmission circuit 12 to transmit corresponding data, depending on the communication results. The power transmission circuit 11 has a bidirectional power transmission function, and can, for example, receive input power from one of the first and second transmission ports P1 and P2 and output the input power to the other transmission port. The input power received by the power transmission circuit 11 is also used as operating power for related internal components of the control device C1.

[0052] The following description will be made with reference to FIG. 8. FIG. 8 is a circuit block diagram of a control device according to an embodiment of the present invention. Compared with FIG. 7, an auxiliary controller 15 is added to the structure of the control device shown in FIG. 8. Only the differences will be described here, and the description of elements with the same reference numerals will refer to FIG. 7. The auxiliary controller 15 in the control circuit 1a shown in FIG. 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 a power supply through 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 an embodiment, the auxiliary controller 15 may separately process the audio data in the display signal of the handheld device 20 and then output the audio signal to the data transmission circuit 12. At this time, the data transmission circuit 12 may output the video data (obtainable from the first transmission port P1) and the audio data (obtainable from the auxiliary controller 15) in 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 FIG. 8 supports independent reception of video data and audio data. This differs from the display device 21 connected to the second transmission port P2 in FIG. 7, which supports a single video and audio transmission interface capable of simultaneously receiving video data and audio data. This single video and audio transmission interface is, for example, a Display Port (DP) transmission interface. That is, the auxiliary controller 15 of the control device C1 shown in FIG. 8 may separately extract and process audio data from the DP display signal provided by the handheld device 20 via the first transmission port P1, and output the audio data 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 audio data independent of video data, can still properly play the video data and the independent audio data in the DP display signal after receiving them.

[0056] The following description will be made with reference to Fig. 9. Fig. 9 is a circuit block diagram of a control device according to an embodiment of the present invention. Compared with Fig. 8, a third transmission port P3 is added to the structure of the control device C2 shown in Fig. 9. Only the differences will be described here, and Figs. 7 and 8 will be referred to for a description of elements with the same reference numerals. The third transmission port P3 shown in Fig. 9 is connected to a data transmission circuit 12 and a power transmission circuit 11.

[0057] 9, a first external device to be connected to the second transmission port P2 and a second external device to be connected to the third transmission port P3 are determined. In one embodiment, the control circuit 1b controls the device so that it determines to use the charging device 22 as the first external device and the display device 21 as the second external device.

[0058] For example, if the handheld device 20 is connected only to the first transmission port P1 of the control device C2, the transmission controller 10 communicates with the handheld device 20 through the first transmission port P1, and then controls the power transmission circuit 11 to receive the first input power from the handheld device 20 through the first transmission port P1. The first input power may 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 then the charging device 22 is connected to the second transmission port P2, the transmission controller 10 will communicate with the handheld device 20 through the first transmission port P1 and with the charging device 22 through the second transmission port P2. After that, the transmission controller 10 controls the power transmission circuit 11 to receive the second input power from the charging device 22 through the second transmission port P2. This second input power may be distributed to the transmission controller 10, the auxiliary controller 15, and the peripheral controller 13 for use, and may also charge the handheld device 20 through the first transmission port P1 and power the display device 21 through the third transmission port P3.

[0060] Furthermore, the transmission controller 10 controls the data transmission circuit 12 to receive the display signal of the handheld device 20. The data transmission circuit 12 then outputs the display signal of the handheld device 20 to the display device 21 via the third transmission port P3 for playback. Taking the structure shown in FIG. 9 as an example, if the display signal of the handheld device 20 is a DP display signal, when the DP display signal is input into the control device C2 via the first transmission port P1, the DP display signal is divided into two signals, video data and audio data, and transmitted separately. Here, the video data in the DP display signal is directly output to the data transmission circuit 12, while the audio data in the DP display signal is transmitted to the auxiliary controller 15, where it is processed by the auxiliary controller 15 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 the DP display signal to the display device 21 for playback.

[0061] In one embodiment, after the handheld device 20 is connected to the control device C2 of FIG. 9, if the charging device 22 is first connected to the second transmission port P2 and then the display device 21 is connected to the third transmission port P3, the transmission controller 10 may detect this situation and control the display device 21 to stop functioning.

[0062] In one embodiment, after the handheld device 20 is connected to the control device C2 of FIG. 9, if the display device 21 is connected only to the third transmission port P3, the transmission controller 10 may detect this situation and control the display device 21 to stop functioning.

[0063] The following description will be made 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 additionally includes a detection controller 16 and another data transmission circuit (e.g., a second data transmission circuit 122). Only differences will be described here, and the description of elements with the same reference numerals will refer to the previous embodiments.

[0064] 10, the first external device connected to the second transmission port P2 and the second external device connected to the third transmission port P3 are not determined. 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 under 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. Alternatively, either the first external device or the second external device may be a combination of a charging device (or a display device) and an input device (e.g., a mouse or a keyboard).

[0065] The detection controller 16 in FIG. 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. A third recognition pin of the transmission controller 10 may be connected to the detection controller 16, and the transmission controller 10 communicates with an external device connected to the third transmission port P3 through the third recognition pin. The third recognition pin of the transmission controller 10 recognizes a second external device connected to the third transmission port P3 through the detection controller 16. In another embodiment, 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] 10, after the handheld device 20 is connected to the first transmission port P1 of the control device C3, if 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, 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. The transmission controller 10 then controls the power transmission circuit 11 to obtain the second input power from the charging device 22 via the second transmission port P2. The power transmission circuit 11 may further distribute the second input power to 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 power the display device 21 via the third transmission port P3. At the same time, the transmission controller 10 controls the second data transmission circuit 122 to obtain the display signal of the handheld device 20, and the second data transmission circuit 122 outputs the display signal of the handheld device 20 to the display device for playback via the third transmission port P3.

[0067] 10, after the handheld device 20 is connected to the first transmission port P1 of the control device C3, if 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, 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. The transmission controller 10 then controls the power transmission circuit 11 to obtain the second input power from the charging device 22 via the third transmission port P3. The power transmission circuit 11 may further distribute the second input power to 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 power the display device 21 via the second transmission port P2. At the same time, the transmission controller 10 controls the first data transmission circuit 121 to obtain the display signal of the handheld device 20, and the first data transmission circuit 121 outputs the display signal of the handheld device 20 to the display device 21 for playback via the second transmission port P2.

[0068] The following description will be made 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, a command interface LD is added to the structure of the control device C3 shown in Figure 11. Only the differences will be described here, and the description of the elements with the same reference numerals will refer to the previous embodiments.

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

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

[0071] 8 to 11 is suitable for a case where the display device 21 connected to the control device C1 independently uses the audio data in the DP display signal. On the other hand, if the display device 21 connected to the control device C1 directly supports the DP display signal (i.e., the audio data in the DP display signal is not independently used), the control device C1 does not need to use the auxiliary controller 15, and the display signal from the first transmission port P1 is directly transmitted 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 conforming to the USB (Universal Serial Bus) Type-C standard. The first recognition pin, the second recognition pin, and the third recognition pin of the transmission controller 10 communicate with devices 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 devices based on the CC channel signals of the 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 supporting Display Port (DP) video functionality. This allows a display signal from the handheld device 20 to be output to another display device via the control device C1, causing the display device to play the video and audio contained in the 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, and may also be combined with other associated circuit elements and firmware to implement the above-described functions and processes.

[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>

Therefore, all equivalent technical modifications made using the specification and drawings of the present invention are included in the scope of the claims of the present invention.
