Based on the above mobile terminal hardware structure and the communication network system, various embodiments of the method of the present invention are provided.
The invention provides a video output method of a docking station, which is applied to the docking station, as shown in figure 3, and comprises a video module, an expansion module and a device source interface, wherein the video module comprises the video interface, the expansion module comprises a data interface, and the device source interface is used for being electrically connected with a device source end. Specifically, the video interface is an HDMI interface (High Definition Multimedia Interface, high-definition multimedia interface), and the HDMI can simultaneously send audio and video signals. The data interface comprises one or more of a USB3.0 interface, a USB2.0 interface, an SD interface, a TF interface and a Type-C interface. The applicability of the docking station is improved by providing a plurality of data interfaces. The device source interface comprises a Type-c interface, and the Type-c interface is more and more favored by consumers along with the popularization of the Type-c interface on notebooks and mobile phones. Therefore, the uplink port of the docking station is also designed to be a Type-c port so as to adapt to the development requirements of the market.
In a first embodiment of the docking station video output method, referring to fig. 4, the method comprises the steps of:
step S10: when the preset condition is met, the signal switching module receives a switching instruction;
step S20: after receiving the switching instruction, the signal switching module disconnects a first signal channel between the signal switching module and the expansion module and communicates a second signal channel between the signal switching module and the video module, so that a video signal can sequentially pass through a third signal channel between the equipment source interface, the signal switching module and the equipment source interface, the signal switching module, the second signal channel and the video module for output.
Aiming at the technical problems that in the prior art, the video output of a docking station can only support the video definition output of 8K30 frames, can not be switched to the video output with higher definition smoothness, and can not meet the better ornamental requirement of a user.
In order to solve the technical problem, in this embodiment, when the preset condition is met, the signal channel resource connected with the extension module is supplied to the video module for use, so that the video module adds a signal channel on the basis of the original signal channel, and the transmission amount of video output is increased, thereby achieving the video output with higher definition and smoothness, and meeting the better viewing requirements of users.
Specifically, a fourth signal channel is arranged between the equipment source interface and the video module, so that the video signal can be sequentially output through the equipment source interface, the fourth signal channel and the video module. The fourth signal channel is the original signal channel between the device source interface and the video module. It can be understood that before switching, the device source interface may be connected to the video module through the fourth signal channel, or sequentially connected to the expansion module through the third signal channel, the signal switching module, and the first signal channel, so that the data interface is utilized to perform data transmission, and the video interface may also be utilized to perform video output.
Specifically, in order to ensure that the video format of the equipment source end can smoothly utilize the second signal channel to output video, the instruction module can send a switching instruction to the signal switching module and simultaneously send a signal conversion instruction to the equipment source end through the equipment source interface, so that the equipment source end converts the video format into a corresponding format type capable of being transmitted through the second signal channel in advance.
Specifically, the first signal path includes RXP-RXN-TXP-TXN, the second signal path includes RX2P-RX2N-RX3P-RX3N, and the fourth signal path includes RX0P-RX0N-RX1P-RX1N. In this way, considering that the data interface and the device source interface are mainly used for data transmission, the data transmission involves data output and data input, so that the corresponding differential input terminal (RXP-RXN) and the corresponding differential output terminal (TXP-TXN) are required to be correspondingly provided, and a differential transmission group is formed by combining the differential input terminal and the differential output terminal for data transmission, so that the corresponding four transmission lines are required to be configured on the first signal channel and the third signal channel. When the signal switching module is switched to be connected to the video module, only the differential input terminals (which can be input from the viewpoint of the video module) are reserved because the video output is mainly involved, and two sets of differential input terminals RX2 (RX 2P-RX 2N) and RX3 (RX 3P-RX 3N) are designed because two transmission lines (TXP-TXN) are left idle at this time on the third signal path. And then, the other two groups of differential input ends RX0 (RX 0P-RX 0N) and RX1 (RX 1P-RX 1N) which are configured on the fourth signal channel are matched to work through the four groups of differential input ends so as to improve the video output effect.
Further, a second embodiment of the present docking station video output method is proposed based on the first embodiment, and referring to fig. 5, in step S10, the method includes the steps of:
