The following description will be made in more detail with reference to fig. 1 and 3 by taking internal components of the first device 100 and the second device 300 as examples.
Referring to fig. 1, in this embodiment, the first device 100 can provide the required power for the second device 300. Therefore, in this embodiment, the first device 100 may include a power module 110 and a microprocessor 120. The power module 110 may include a power control device 111, a power monitoring device 112 and a power output device 113. The power control device 111 may be a power control chip for controlling the output power of the first device 100. The power monitor 112 is used to monitor the output power of the first device 100. The power output device 113 is used for outputting power to the second device 300.
The microprocessor 120 may include at least one attribute identification device 121 and a communication device 122. The microprocessor 120 can communicate with the second device 300 via the communication device 122, and can read the memory device 210 of the signal transmission device 200 via the communication device 122 to obtain the Attribute information Attribute _ Info. The Attribute identification device 121 is used to determine at least one Attribute of the signal transmission device 200 according to the obtained Attribute information Attribute _ Info.
The second device 300 may include one or more functional blocks (shown in phantom) and a microprocessor 320. The functional blocks may include, for example, but not limited to, a panel device 331, a wired communication device 332, a wireless communication device 333, a speaker device 334, etc. The panel device 331 is used for displaying video signals, such as video signals provided by the first device 100. The wired communication device 332 is used to provide wired communication functions, for example, to enable the second device 300 to perform wired communication with an external device through an ethernet network. The wireless communication device 333 is used to provide wireless communication functions, for example, enabling the second device 300 to communicate with external devices through WiFi. The microprocessor 320 may include at least one communication device 322. The microprocessor 320 can communicate with the first device 100 via the communication device 322 to obtain the required information.
It should be noted that the attribute identifying device 121 and the communication devices 122 and 322 can be implemented by software and/or firmware modules, respectively, or can be implemented by dedicated hardware. When the attribute identification device 121 and the communication device 122,322 are implemented by software and/or firmware modules, the microprocessor 120,320 can perform corresponding operations by executing corresponding program codes, and when the microprocessor 120,320 performs corresponding operations by executing corresponding program codes, the software or firmware modules can be regarded as dedicated hardware, for example, as a subunit of the microprocessor 120 or 320. In addition, those skilled in the art will appreciate that the first device 100 and the second device 300 may include other elements not shown in FIG. 1 to implement the required functions.
According to an embodiment of the present invention, when identifying the signal transmission device, the microprocessor 120 of the first device 100 can first read the memory device 210 of the signal transmission device 200 through the communication device 122 to obtain the Attribute information Attribute _ Info. The obtained Attribute information Attribute _ Info may be provided to the Attribute identifying device 121 for determining at least one Attribute of the signal transmitting device 200 according to the obtained Attribute information Attribute _ Info. Such as the applicable power range of the signal transmission apparatus 200. Then, the microprocessor 120 can set the maximum output power of the power module 110 according to the applicable power range of the signal transmission device 200, and notify the second device 300 of the acquired attribute information or the set value through the communication device 122.

When the power control device 111 determines that the output power is too large, the power control device 111 controls the power output device 113 to reduce the output power, or reduce the output voltage or current, so that the power of the signal transmitted through the signal transmission device 200 can be properly controlled within the applicable power range of the signal transmission device 200.
It should be noted that the reading of the Attribute information Attribute _ Info, the Attribute identification of the signal transmission device 200, the power supply and the control of the output power/power (or the output voltage, current) are not limited to be implemented in the first device 100. One or more of the foregoing operations may also be implemented in the second device 300.
FIG. 4 is a block diagram of a signal processing system according to another embodiment of the present invention. The signal processing system shown in FIG. 4 is similar to the signal processing system shown in FIG. 1, except that the microprocessor 320 of the second device 300 further includes an attribute identification device 321. When the signal transmission device 200 is identified, the microprocessor 320 of the second device 300 can first read the memory device 210 of the signal transmission device 200 through the communication device 322 to obtain the Attribute information Attribute _ Info. The obtained Attribute information Attribute _ Info may be provided to the Attribute identification device 321 for determining at least one Attribute of the signal transmission device 200 according to the obtained Attribute information Attribute _ Info. Such as the applicable power range of the signal transmission apparatus 200. The microprocessor 320 can then notify the first device 100 of the obtained attribute information via the communication device 322. For example, the second device 300 can send a notification message to the first device 100 through the communication device 322 to notify the first device 100 of the property of the signal transmission device 200, such as the aforementioned applicable power range.
After the attribute of the signal transmission device 200 is known, the microprocessor 120 of the first device 100 can make relevant settings according to the information, for example, set the maximum output power of the power module 110, and can further notify the second device 300 of the setting value through the communication device 122. After determining the setting value, such as the maximum output power, of the signal transmitted through the signal transmission device 200 according to the attribute of the signal transmission device 200, the following operations may be similar to the embodiment shown in fig. 1.
It should be noted that fig. 1 and 4 only show some exemplary system architectures in which the present invention can be implemented, but the application of the present invention is not limited thereto.

In this embodiment, the second device 300 may comprise a power module for providing power to the first device 100 and controlling and monitoring the output power. For example, the second device 300 may set the maximum value or the minimum value of the power (or the current, the voltage) of the output signal according to the attribute of the signal transmission device 200, and may further send a notification message to the first device 100 to notify the first device 100 of the maximum value or the minimum value of the power (or the current, the voltage) of the signal set by the first device.
In addition, it should be noted that fig. 1 and 4 only show the components relevant to the present invention. Those skilled in the art will appreciate that the signal processing system may include other components not shown in fig. 1 and 4 to perform the desired signal processing functions. Further, it is noted that fig. 1 and 4 are drawn by way of example, wherein the elements are not necessarily drawn to scale.
According to an embodiment of the present invention, the memory device 210 may further store a Code information Code specific to the signal transmission device 200. Different signal transmission devices 200 may have different dedicated codes. For example, when the signal transmission device 200 is a cable, each cable has a respective dedicated code, i.e., different cables have different dedicated codes. After the signal transmission device 200 is connected to the signal processing system and before the signal transmission starts, the first device 100 and/or the second device 300 can read the Code information Code of the signal transmission device 200 from the memory device 210, and determine whether the signal transmission device 200 is a signal transmission device allowed to be used in the signal processing system according to the Code information Code. For example, the first device 100 and/or the second device 300 may obtain the manufacturer information of the signal transmission device 200, the product authorization information of the signal transmission device 200, the product authentication information of the signal transmission device 200, and the like from the dedicated Code information Code, and determine whether the signal transmission device 200 is a signal transmission device allowed to be used in the signal processing system according to the information. If so, the first device 100 and the second device 300 can start to transmit signals through the signal transmission device 200. If not, the first device 100 and the second device 300 can choose not to transmit signals through the signal transmission device 200, so as to avoid the problem that devices in the system are damaged due to the non-compliance of the specification of the signal transmission device 200 caused by the failure to identify the attribute or specification of the signal transmission device 200. When only one of the first device 100 and the second device 300 determines that the signal transmission device 200 is a signal transmission device allowed to be used in the signal processing system by the Code information Code of the signal transmission device 200, the other device may be notified of the determination result.
In summary, the signal transmission device identification method and the signal processing system implementing the signal transmission device identification provided by the present invention can properly control the operation of the signal processing system according to the attribute information of the signal transmission device, and can also avoid the problem that the signal transmission device which cannot be identified or is unauthorized or unauthenticated is mistakenly connected to the signal processing system, which may cause the unexpected device to be overheated or damaged.
